Inspection of Towing Vessels

AGENCY: Coast Guard, DHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Coast Guard is establishing safety regulations governing 
the inspection, standards, and safety management systems of towing 
vessels. We are taking this action because the Coast Guard and Maritime 
Transportation Act of 2004 reclassified towing vessels as vessels 
subject to inspection and authorized the Secretary of the Department of 
Homeland Security to establish requirements for a safety management 
system appropriate for the characteristics, methods of operation, and 
nature of service of towing vessels. This rule, which includes 
provisions covering specific electrical and machinery requirements for 
new and existing towing vessels, the use and approval of third-party 
organizations, and procedures for obtaining Certificates of Inspection, 
will become effective July 20, 2016. However, certain existing towing 
vessels subject to this rule will have an additional 2 years before 
having to comply with most of its requirements.

DATES: This final rule is effective July 20, 2016. The incorporation by 
reference of certain publications listed in the final rule is approved 
by the Director of the Federal Register on July 20, 2016.

ADDRESSES: Comments and material received from the public, as well as 
documents mentioned in this preamble as being available in the docket, 
are part of docket USCG-2006-24412 and are available on the Internet by

II. Executive Summary

A. Purpose and Authority

    In 2004, Congress reclassified towing vessels as vessels subject to 
inspection under part B of subtitle II of title 46, United States Code 
(U.S.C.), and authorized the Secretary of Homeland Security to 
establish requirements for the inspection of towing vessels, their 
possible use of safety management

[[Page 40005]]

systems (SMS) and hours of service requirements for them. The 
legislative history, which pointed to the need for a ``full safety 
inspection of towing vessels,'' references two towing vessel incidents 
involving a total of 19 deaths. In September 2001, a towing vessel 
struck a bridge at South Padre Island, TX. The bridge collapsed, and 5 
people died when their cars or trucks went into the water. On May 26, 
2002, a towing vessel struck the I-40 highway bridge over the Arkansas 
River at Webber Falls, OK. The bridge collapsed, and 14 people died 
when their cars or trucks went into the Arkansas River. 150 Cong. Rec. 
H6469-01, 2004 WL 1630278; and H.R. Conf. Rep. 108-617, 2004 
U.S.C.C.A.N. 936, 951.
    This final rule implements most provisions of the Notice of 
Proposed Rulemaking (NPRM)(76 FR 49976, Aug. 11, 2011) as proposed, but 
makes changes to address concerns of the public and industry expressed 
in comments, as is explained below. This rule is authorized and made 
necessary by the Coast Guard and Maritime Transportation Act of 2004 
(2004 Act), Public Law 108-293, 118 Stat. 1028 (Aug. 9, 2004), which 
made towing vessels subject to inspection. Six years later, the Coast 
Guard Authorization Act of 2010 (2010 Act), Public Law 111-281, 124 
Stat. 2905 (Oct. 15, 2010), directed the Secretary to issue a notice of 
proposed rulemaking and a final rule.

B. Overview of Rule

    This rule creates a comprehensive safety system that includes 
company compliance, vessel compliance, vessel standards, and oversight 
in a new Code of Federal Regulations (CFR) subchapter dedicated to 
towing vessels. This rule, which (with exceptions) generally applies to 
all U.S.-flag towing vessels 26 feet or more, and those less than 26 
feet moving a barge carrying oil or hazardous material in bulk, lays 
out both inspection mechanisms as well as new equipment, construction, 
and operational requirements for towing vessels.
    To provide flexibility, vessel operators will have the choice of 
two inspection regimes. Under the Towing Safety Management System 
(TSMS) option, routine inspections of towing vessels will primarily be 
performed by third-party organizations (TPOs), including certain 
classification societies, and this rule creates a framework for 
oversight and audits of such TPOs by the Coast Guard. The TSMS will 
provide those operators with the flexibility to tailor their safety 
management system to their own needs, while still ensuring an overall 
level of safety acceptable to the Coast Guard. Alternatively, under the 
Coast Guard inspection option, routine inspections would be conducted 
by the Coast Guard, providing an option for those operators who choose 
not to develop and implement their own TSMS.
    The rule also creates many new requirements for design, 
construction, equipment, and operation of towing vessels. Those 
requirements are typically based on industry consensus standards or 
existing Coast Guard requirements for similar vessels. To develop these 
requirements for towing vessels, the Coast Guard started by publishing 
a notice in 2004 (69 FR 78471) that asked questions and announced 
public meetings to seek guidance in implementing the 2004 Act 
provisions. We also worked with the Towing Safety Advisory Committee 
(TSAC), industry groups, and a contractor (ABSG Consulting--tasked with 
providing an industry analysis) to better gauge how to proceed with 
this rulemaking. We evaluated existing requirements for towing vessels 
(contained primarily in 46 CFR part 27 and subchapter I) to determine 
whether they were adequate for towing vessels and meet the intent of 
the 2004 Act. As discussed in greater detail below, the safety 
requirements in this final rule align with industry consensus 
standards, and we consider it very likely that most towing vessels 
already comply with most of them.
    We made several changes to our proposal in the NPRM. We have 
clarified the system for Coast Guard oversight and inspection of towing 
vessels that complements the TPO system the Coast Guard proposed. To 
address concerns about the cost impact of the rule, we have added 
``grandfathering'' provisions to several requirements, so the 
requirements will not apply to existing vessels or vessels whose 
construction began before the effective date of the rule. We also 
reorganized several parts for greater clarity or to better align with 
the existing text of other parts of the CFR. Finally, as we noted in 
the NPRM (76 FR 49985), we still plan to promulgate a separate 
rulemaking for an annual inspection fee for towing vessels that will 
reflect the specific program costs associated with the TSMS and Coast 
Guard inspection options. Until then we are establishing the existing 
fee of $1,030 in 46 CFR 2.10-101 for any inspected vessel not listed in 
Table 2.10-101 as the annual inspection fee for towing vessels subject 
to subchapter M. As reflected in 46 CFR 2.10-1(b), this fee would not 
be charged for a vessel being inspected for the initial issuance of a 
COI, but the fee would be charged annually starting a year later.

C. Costs and Benefits

    This rule will affect approximately 5,509 U.S. flag towing vessels 
engaged in pushing, pulling, or hauling alongside, and the 1,096 
companies that own or operate them. Towing vessels not covered by this 
rule include towing vessels inspected under subchapter I, work boats, 
and recreational vessel towing vessels.
    The estimate for total industry and net government costs is $41.5 
million annualized at a 7 percent discount rate over a 10-year period 
of analysis. The estimate for monetized benefits is $46.4 million 
annualized at a 7 percent discount rate, based on the mitigation of 
risks from towing vessel accidents in terms of lives lost, injuries, 
oil spilled, and property damage.
    Subtracting the annualized monetized costs from the annualized 
monetized benefits yields a net benefit of $4.9 million. We also 
identified, but did not monetize, other benefits from reducing the risk 
of accidents that have secondary consequences of delays and congestions 
on waterways, highways, and railroads.

III. Regulatory History

A. Statutory Background

    The Coast Guard and Maritime Transportation Act of 2004 (2004 Act), 
Public Law 108-293, 118 Stat. 1028 (Aug. 9, 2004), established new 
authorities for towing vessels as follows:
    The 2004 Act added ``towing vessels'' as a class of vessels that 
are subject to safety inspections. See section 415 of the 2004 Act, 
which amended section 3301 of title 46 of the U.S.C. (46 U.S.C. 3301). 
The term ``towing vessel'' was already defined in 46 U.S.C. 2101, and 
the scope and standards of safety inspections are laid out in 46 U.S.C. 
3305.
    The 2004 Act also authorized the Secretary of Homeland Security to 
establish, by regulation, a safety management system appropriate for 
the characteristics, methods of operation, and nature of service of 
towing vessels.
    See Section 415 of the 2004 Act, which amended 46 U.S.C. 3306(j).

B. Regulatory Background

    On December 30, 2004, the Coast Guard published a request for 
comments and notice of public meetings titled ``Inspection of Towing 
Vessels'' in the Federal Register (69 FR 78471). The notice asked seven 
questions regarding how the Coast Guard should move forward with the 
rulemaking to implement the statutory provisions from

[[Page 40006]]

the 2004 Act, listed above in section III.A. ``Statutory background.'' 
The Coast Guard then held four public meetings, one each in Washington, 
DC; Oakland, CA; New Orleans, LA; and St. Louis, MO. In addition to the 
comments the Coast Guard received at the public meetings, there were 
117 comments submitted to the docket, which can be found in docket 
USCG-2004-19977 at http://www.regulations.gov. The Coast Guard used the 
public input received to inform its development of the NPRM.
    On August 11, 2011, the Coast Guard published an NPRM titled 
``Inspection of Towing Vessels'' in the Federal Register (76 FR 49976). 
The Coast Guard then held four public meetings, one each in Newport 
News, VA; New Orleans, LA; St. Louis, MO; and Seattle, WA. The comment 
period was open until December 9, 2011. We received and considered a 
combined total of more than 3,000 comments from more than 265 written 
submissions and oral statements from 105 persons at public meetings.

IV. Discussion of Comments and Changes

A. General Feedback on the NPRM

    For clarity, the following discussion of comments is sorted by 
topic, which primarily corresponds to parts of the CFR as noted in the 
Table of Contents.
    Parts 1 and 2 are in title 46 CFR subchapter A, part 15 is in 
subchapter B, part 199 is in subchapter W, and all other parts are in 
the newly created subchapter M. Where changes in response to a comment 
led to changes outside the designated section or part, we have noted it 
in the text. Within each topic of the rule, comments have been 
addressed in order of the section they applied to. When public 
submissions addressed multiple sections of the proposed rule or it 
wasn't clear what specific sections they addressed, we responded to 
their comments in the section that seemed most appropriate. In 
addition, we have made numerous changes through the regulatory text 
that are entirely non-substantive and editorial in nature; for example, 
changing ``chapter'' to ``Chapter'' or ``onboard'' to ``on board'' in 
certain contexts to better conform to standard usage.
    We received several comments in general support of the proposed 
inspection regime, design standards, and SMS requirements for towing 
vessels. Individuals and maritime companies felt that the proposed 
regulation would serve to improve the safety, security, and 
environmental protection of towing vessel operations.
    We also received several comments from individuals and maritime 
companies that generally opposed the proposed regulation. Some 
commenters expressed concern that the elements of the proposed rule 
would impose added cost burdens on business, which might lead to 
termination of positions.
    The Coast Guard acknowledges these comments and concerns. However, 
we do not expect towing companies and businesses to eliminate positions 
or downsize as a result of this rulemaking. See the Regulatory Analysis 
for our discussion of this issue.
    One comment agreed with the American Bureau of Shipping Group's 
(ABSG's) recommendation that a traditional, inspected vessel option be 
offered as an alternative for those companies that did not maintain 
documentation of policies and procedures, and for those smaller 
companies who would not be able to implement a SMS. As we noted in the 
NPRM (76 FR 49978), we contracted with ABSG Consulting in 2006 for 
assistance with gathering data and categorizing the vessels that make 
up the towing industry; see their report, which also contains 
recommendations, in the docket, USCG-2006-24412-0017.
    We concur with the commenter and the cited ABSG recommendation. As 
an alternative to a TSMS, the proposed rule included the option of a 
Coast Guard inspection regime. We have kept both of these options in 
this final rule.
    Citing an 80-page NPRM, more than 2,000 pages of supporting 
documentation, and a short comment period, one commenter requested an 
extension of the comment period so smaller operators can review how the 
proposed requirements would impact their businesses. The Coast Guard 
did not grant this request; we provided a 120-day comment period, which 
is longer than our standard 90-day comment period, and also held four 
public meetings in that time. We believe there was sufficient 
opportunity to comment on the NPRM.

B. Background and Need for Regulation

    We received one comment noting that the 2010 Act no longer exempted 
towing vessels of less than 200 tons engaged in exploiting offshore 
minerals or oil from 46 U.S.C. 8904 and regulations promulgated under 
that authority, and therefore Sec.  15.535(b) should be revised. See 
section 606 of that Act. We agree with the commenter that the exemption 
is no longer valid and so we adopted the commenter's requested 
amendment to Sec.  15.535.
    We received comments from several commenters who supported the work 
conducted by TSAC working groups. For NPRM discussion of work by these 
groups, see 76 FR 49978. Other commenters commended the Coast Guard's 
efforts in incorporating suggestions provided by TSAC. One commenter 
explained that a quote in the preamble, regarding the devastating 
impact that a TSMS can have on smaller companies, was incorrectly 
attributed to the TSAC Economic Analysis Working Group.
    The commenter, a trade association, went on to explain that 
according to the experience of its members, TSMSs have had a positive 
impact on the safety performance and success of many small companies.
    As we have previously noted, we greatly appreciate TSAC's 
contributions to the development of the NPRM. The quote we attributed 
to the TSAC Economic Working Group regarding the devastating impact 
that a TSMS requirement can have on smaller companies was taken from an 
earlier version of the working group's report; the quote should have 
read ``To conduct internal audits on a large fleet, this may mean 
hiring a full-time staff, including salary, training and travel costs. 
While large companies will spend more to implement and maintain a SMS, 
however, the costs to a small company may be more difficult to 
absorb.'' See page 4 of the TSAC Economic Analysis Working Group 
Report, Dec. 16, 2008, document USCG-2006-24412-0007 in the docket. We 
are not surprised by the statement that TSMSs have had a positive 
impact on the safety performance and success of safety operators; we 
included TSMS as an option because we believe TSMSs will provide a 
positive impact on the safe operation of towing vessels. For data 
supporting this assessment, see the Regulatory Analysis for this final 
rule in the docket.
    One commenter recommended that rather than writing a costly new set 
of regulations, the Coast Guard should give consideration to 
consolidating the rules already in place. The commenter recalled a 
voluntary program from a 2009 ``United States Coast Guard Requirements 
for Uninspected Towing Vessels'' document that issued stickers to 
vessels that had been reviewed for compliance with current regulations.
    The Coast Guard established the voluntary Towing Vessel Bridging 
Program in 2009 to ease the transition of towing vessels going from a 
status of uninspected to inspected, and to ensure that both the Coast 
Guard and the towing vessel industry are informed and prepared to meet 
requirements coming from this Inspection of Towing Vessels

[[Page 40007]]

rulemaking. As we noted in the NPRM, the Coast Guard considered 
existing regulations but decided the standards or regulations found in 
other vessel inspection subchapters were not appropriate and did not 
fulfill the intent of the 2004 Act. (76 FR 49987, Aug. 11, 2011.) The 
unique nature of the towing industry and towing operations warrants the 
development of new standards and regulations that pertain exclusively 
to towing vessels. In addition to the TSMS, this final rule contains 
other towing vessel-specific provisions, including expansion of the use 
of TPOs as part of the Coast Guard's TSMS-based, towing vessel 
inspection for certification regime. The Towing Vessel Bridging Program 
is a transition program based on voluntary compliance; it is not a 
substitute for a comprehensive regulatory regime that addresses and 
enforces safety requirements for towing vessels that Congress 
envisioned when it added towing vessels to the list of vessels subject 
to inspection.
    We received comments from individuals and maritime companies who 
disagreed with the need for the proposed regulations, either because 
lack of vessel regulations were not the cause of the problem or the 
proposed regulations were not risk-based. Three commenters noted that 
some casualties occur because of human error, not from a lack of 
regulation. One individual felt that the Mississippi River accident in 
2008 was not a good example in support of additional regulation, 
because the accident was caused by irresponsible behavior of the pilot.
    The Coast Guard recognizes that human error is the cause of some 
casualties and that no amount of regulations will eliminate human 
error. To the extent we are able, however, we have attempted to adopt 
regulations that help ensure the safe operation of towing vessels, 
including some regulations intended to address factors related to human 
error. A fully functional safety management system, such as a TSMS, is 
continuously updated and evolving based on the non-conformities 
observed and the lessons learned as a result of reviewing incidents--
including those related to human error. The TSMS option should help 
ensure that towing vessels are operated more safely and in full 
compliance with the TSMS and regulations in subchapter M. The Coast 
Guard inspection option may provide less frequent feedback to vessel 
operators and crew, but it too is intended to ensure compliance with 
regulations in subchapter M.
    Two commenters, an individual and a towing company, felt that the 
regulations are not based on risk. A company asserted that a risk-based 
approach supported by towing vessel casualty data should be the main 
motivation behind the application and development of towing vessel 
safety regulation.
    As reflected in discussions below regarding specific requirements, 
the Coast Guard has used a risk-based approach in this rulemaking. We 
have reviewed comments on cost and other assumptions on which we based 
our proposed rule and have made changes when appropriate to ensure that 
this final rule is risk-based. For data supporting this assessment, see 
the Regulatory Analysis for the final rule.
    One commenter indicated that the Coast Guard's Marine Safety 
Directorate has not sought to help working mariners. The commenter 
praised Congress for amending 46 U.S.C. 2114 to protect a seaman 
against discrimination if he or she testifies in a proceeding brought 
to enforce a maritime safety law or regulation, or engages in certain 
other actions involving the seaman's work, or participates in a safety 
investigation by the Department of Homeland Security or National 
Transportation Safety Board (NTSB). The commenter listed four areas 
where mariners' safety, health, and welfare, in the commenter's view, 
were largely unprotected: Workplace safety on uninspected dry cargo 
barges, hearing protection and noise prevention, asbestos, and personal 
protective equipment. The same commenter urged Congress to transfer 
authority over workplace inspection, drafting safety regulations, and 
requiring proper maintenance of barges from the Occupational Safety and 
Health Administration (OSHA) to the Coast Guard. This commenter also 
recommended areas in which the NPRM should be revised to promote 
workplace safety and health regulations, including training of Coast 
Guard inspectors in OSHA-workplace-safety regulations and the use of 
personal protective equipment.
    The Coast Guard notes the commenter's concern; the commenter's 
specific suggested revisions to the regulations proposed in the NPRM 
are addressed below where we discuss 46 CFR part 140, Operations, which 
includes subparts on crew safety and safety and health, and other parts 
addressed by this commenter.

C. Organization, General Course, and Methods Governing Marine Safety 
Functions (Part 1)

    In our NPRM, we did not propose to amend part 1, but in this final 
rule we added Sec.  1.03-55 to address comments on the appeals process 
for a company whose certificate is rescinded. See section IV.H below. 
Our proposed Sec.  136.180 pointed to 46 CFR 1.03 for those seeking to 
appeal, but we saw the need to identify the Coast Guard official or 
entity that appeals should be directed to, including the appeal of 
matters relating to action of a third party, such as when a TPO 
rescinds a TSMS certificate.

D. User Fees and Inspection Table (Part 2)

    Part 2 of 46 CFR is in subchapter A. We received two comments 
regarding user fees. An association asked the Coast Guard to clarify 
whether those choosing both the TSMS and the Coast Guard inspection 
options will have to pay whatever user fee is assessed in the final 
rule to recover the costs of the entire new towing vessel inspection 
program. Another commenter asserted that charging user fees to finance 
the implementation of regulation that is not risk-based will return 
little value to the industry.
    Under 46 U.S.C. 2110 and the Coast Guard's regulations in 46 CFR 
subpart 2.10, the Coast Guard is required to charge a fee for services 
provided for vessels required to have a Certificate of Inspection 
(COI). Subpart 2.10 fees, however, do not apply to the initial issuance 
of a COI.
    This fee for services must meet the criteria of 31 U.S.C. 9701 
(Fees and charges for Government services and things of value) to be 
fair and based on the cost to the government, the value of the service 
being provided, the public policy served, and other relevant facts. The 
Office of Management and Budget (OMB) Revised Circular A-25 explains 
that full program costs should be recovered by fees charged.
    In our NPRM, the Coast Guard stated its intent to establish a user 
fee, as required by law, for those vessels required to comply with 
subchapter M, and indicated that this user fee would be established 
through a separate rulemaking process that would commence on or around 
publication of this final rule. The Coast Guard also committed to not 
inspecting towing vessels or issuing COIs to towing vessels until user 
fees were established. (76 FR 49985, August 11, 2011.)
    We still plan to promulgate a separate rulemaking for an annual 
inspection fee specifically for towing vessels, under the authority in 
46 U.S.C. 2110 and 31 U.S.C. 9701, that will consider the specific 
program costs associated with the TSMS and Coast Guard inspection 
options. However, until that time the

[[Page 40008]]

Coast Guard is establishing the existing fee of $1,030 stated in 46 CFR 
2.10-101 as the annual inspection fee for towing vessels subject to 
subchapter M, for any inspected vessel not listed in Table 2.10-101. As 
reflected in 46 CFR 2.10-1(b), this annual inspection fee will not be 
charged for an initial COI inspection, but the fee will be charged 
annually starting a year later. Once this final rule becomes effective, 
the Coast Guard will apply the existing annual fee listed in 46 CFR 
2.10-101, Table 2.10-101 as ``Any inspected vessel not listed in this 
table'' to subchapter M vessels other than those already separately 
listed in the Table. Since all vessels subject to subchapter M will be 
considered inspected vessels and required to obtain COIs, regardless of 
whether the TSMS option is chosen, all subchapter M vessels receiving 
COIs will be charged an annual inspection fee as outlined above.
    User fees charged by the Coast Guard under 46 U.S.C. 2110 do not 
directly finance Coast Guard operations and thus user fees do not 
finance the implementation of the regulations. OMB's Revised Circular 
A-25 explains that user fees are intended to offset the cost of 
providing services to specific beneficiaries.
    Regarding the comment about the lack of value of a user fee to 
finance the implementation of a non-risk-based regulation, we have used 
a risk-based approach in developing this rulemaking and have made 
changes from the proposed rule taking into account commenters concerns 
to ensure that this final rule continues to rely on risk-based 
analysis.
Other Certification Changes
    In the NPRM we stated we would amend the table in subchapter I--and 
in other subchapters--that identified inspection and certification 
regulations applicable to vessels. Our intended amendments to those 
tables were to reflect changes for towing vessels introduced by 
subchapter M (see discussion in 76 FR 49979, August 11, 2011). Since 
the NPRM was published, however, in a separate rulemaking (79 FR 58270, 
58272, September 29, 2014) the Coast Guard removed tables in 46 CFR 
24.05-1, 70.05-1, 90.05-1, and 188.05-1. Those tables replicated a 
table in 46 CFR part 2 dedicated to inspection regulations and thus 
were not necessary.
    Rather than add to the 7-column, 7-page table in 46 CFR 2.01-7(a), 
we have amended the text before and after the table instead. These 
amendments direct towing vessels to a new paragraph (b), which directs 
those subject to this rule to subchapter M for inspection and 
certification regulations, and other towing vessels to Table 2.01-7(a).

E. Manning (Part 15)

    We received approximately 40 comments that addressed the issue of 
manning. Part 15 of 46 CFR is in subchapter B.
    We received several comments stating that the Coast Guard should 
require minimum crew manning levels. One commenter said wheelhouse 
manning is a concern due to the shortage of qualified individuals 
holding the appropriate merchant mariner credential, especially with 
the retirement age approaching for many currently qualified 
individuals. A maritime company said the minimum manning level should 
be included in the COI. Another commenter noted in response to COI 
requirements proposed in part 136 that this regulation should clarify 
the number of required crewmembers and allow the towing vessel to be 
operated by a single crewmember in certain circumstances.
    In accordance with 46 CFR 15.501, the Coast Guard will specify the 
minimum manning for each towing vessel in all of the vessel's areas of 
operation on the vessel's COI, including international and domestic 
operations. We note that Officers in Charge, Marine Inspection (OCMIs) 
will review operational details of the vessel and work with companies 
to make decisions on vessel manning which could indicate various levels 
of manning based on specific routes and service of the towing vessel 
when determining the number of required crewmembers for a towing 
vessel. We do not envision an appreciable increase in the number of 
qualified individuals needed to man inspected towing vessels. The 
influence of market forces on the number of individuals seeking to 
become credentialed operators is beyond the scope of this rulemaking.
    Several commenters opposed any change to the current manning levels 
required for towing vessels, and some commenters recommended specific 
changes to several sections currently in the CFR, such as 33 CFR 
155.710(e) and 46 CFR 15.810(b) and 15.820(a)(3), to avoid inadvertent 
changes to the manning or credentialing requirements given the Coast 
Guard's statement in the NPRM that ``we are not proposing to change any 
of the current manning levels required for towing vessels'' (76 FR 
49990, Aug. 11, 2011).
    As previously stated, the Coast Guard will make a vessel-specific 
assessment of the manning required for a given vessel's operations. The 
minimum manning required for safe operations may differ from one 
operation to another. As with other inspected vessels, this is a 
vessel-specific determination made by the cognizant OCMI.
    The Coast Guard believes the requested change to Sec.  15.820(a)(3) 
is already addressed through existing regulations. For inspected 
vessels 300 gross tons and above that operate on inland waters, 46 CFR 
15.820(a)(3) requires the vessel to have an individual with a license 
or the appropriate merchant mariner credential (MMC) officer 
endorsement if the OCMI determines that such credentials are necessary 
for the person responsible for the vessel's mechanical propulsion. For 
purposes of towing vessels, however, the applicable subchapter B 
definition of ``inland waters'' excludes the Western Rivers. See 46 CFR 
10.107. Therefore, Sec.  15.820(a)(3) does not apply to a towing vessel 
when it is operating on Western Rivers, a term also defined in Sec.  
10.107. Based on a recent survey of the Coast Guard's Marine 
Information for Safety and Law Enforcement (MISLE) database, we have 
concluded that most inland towing vessels 300 gross tons or above 
operate on the Western Rivers. Those towing vessels operating on inland 
waters beyond the Western Rivers may be required to have a credentialed 
individual responsible for the vessel's mechanical propulsion based on 
a vessel-specific assessment conducted by the cognizant OCMI.
    The Coast Guard believes changes to 33 CFR 155.710(e) that would 
allow the use of a letter-of-designation for an inspected towing vessel 
are not warranted. The requirements of 33 CFR 155.710(e)(1) apply to 
all inspected vessels required by 46 CFR chapter I to have an officer 
aboard, including towing vessels that become inspected vessels under 
this rule. Congress made towing vessels a class of vessels subject to 
inspection, and we have no evidence that towing vessels are less likely 
to spill oil than the other inspected vessels already subject to Sec.  
155.710(e)(1). We also see value in uniform requirments for inspected 
vessels conducting the same activities. We note, however, that existing 
Sec.  155.130 provides for exemptions from compliance with the 
requirement if authorized by the COTP or OCMI for reasons such as 
economic or physical impracticality. We therefore believe that adequate 
flexibility already exists in Part 155 to accommodate any unexpected 
consequences of towing vessels becoming subject Sec.  155.710(e)(1).
    The Coast Guard believes changes to 46 CFR 15.810(b), in order to 
exempt towing vessels subject to subchapter M

[[Page 40009]]

from the requirements for a minimum number of mariners holding a 
license or MMC officer endorsement as mate required to be carried on 
certain inspected vessels, are not warranted. Towing vessels are one of 
the several classes of vessels that are authorized to use a two-watch 
system and, as a result, additional mates are unnecessary to comply 
with this level of manning.
    Some commenters urged the Coast Guard to adopt TSAC's 2006 
recommendations to amend proposed 46 CFR 15.535 to incorporate a 
baseline requirement for a safe watch complement. This was intended to 
avoid confusion about the minimum manning that will be required on 
towing vessel COIs and the role of the TSMS in crewing decisions.
    Consistent with our NPRM preamble statement that we were not 
proposing to change any of the current manning levels required for 
towing vessels, we modeled our proposed Sec.  15.535 after Sec.  
15.610, which addresses towing vessel master and mate (pilot) 
requirements on uninspected vessels. But as noted above in section 
IV.B, we made a change in Sec.  15.535 from what we proposed in the 
NPRM. To reflect the 2010 Act's amendment to 46 U.S.C. 8905, we made a 
conforming amendment to Sec.  15.535(b) to remove an non-applicability 
reference to certain towing vessels of less than 200 gross register 
tons engaged in exploiting offshore minerals or oil. While reviewing 
proposed Sec.  15.535 in response to a comment discussed above, we 
noted the need to remove a reference to vessels engaged in assistance 
towing because the applicability of Sec.  15.535 does not include 
vessels engaged in assistance towing. Further, we revised paragraph (a) 
to more clearly state which vessels are subject to Sec.  15.535, to 
specify the vessels not subject to subchapter M that must meet 
requirements Sec.  15.535(b), and to note that all towing vessels 
subject to Sec.  15.535 must also meet requirements in Sec.  15.535(c). 
Finally, we inserted clarifying edits and paragraph headings in Sec.  
15.535 to make it easier to read and understand, and in both Sec. Sec.  
15.535 and 15.610 we clarified that the officer in charge of the vessel 
must provide the evidence to the Coast Guard.
    Also, we made changes to Sec.  15.535 to ensure consistency in the 
nomenclature introduced by the Consolidation of Merchant Mariner 
Qualification Credentials final rule (74 FR 11196, Mar. 16, 2009), and 
to Sec.  15.610 to ensure that this section refers to the remaining 
uninspected towing vessels. Our changes also reflect the recent 
amendments made by the final rule entitled Implementation of the 
Amendments to the International Convention on Standards of Training, 
Certification and Watchkeeping for Seafarers, 1978, and Changes to 
Domestic Endorsements (STCW) (78 FR 77796, Dec. 24, 2013).
    As the authority issuing the vessel's COI, the cognizant OCMI is 
required by law to stipulate the manning for an inspected vessel. See 
46 U.S.C. 3309 and 8101, 33 CFR 1.01-20, and 46 CFR 2.01-5 and 15.501. 
She or he can take a variety of factors into consideration when 
determining the safe manning for a vessel, including recommendations 
from the owner or managing operator. In some cases, existing law or 
regulations specify the minimum manning for a particular voyage, area 
of operation, or vessel service. See e.g., 46 U.S.C. 8301 and 46 CFR 
15.610. In this final rule, 46 CFR 15.535 would set one such minimum. 
An OCMI may specify a level of manning above those minimums specified 
by law if such a level is warranted to safely operate the vessel. See 
46 U.S.C. 8301(d)(2) and 46 CFR 15.501. A vessel's safety management 
system can identify situations where additional manning may be 
warranted (such as high water conditions) but it cannot specify a level 
of manning below the minimum established by the OCMI at any time.
    We received some comments stating that the language used in Sec.  
15.535(c) concerning towing vessels in pilotage waters on the Lower 
Mississippi River is not clear. One commenter said it would be useful 
to define the geographical limits of the ``pilotage waters of the Lower 
Mississippi River'' in Sec.  15.535(c). Another commenter said the 
language should be the same as that used in Sec.  15.610(b).
    The Coast Guard agrees with these comments and has changed the text 
in Sec.  15.535(c) to match the current text of Sec.  15.610(b), except 
for necessary organizational changes and to specify that the evidence 
should be provided to the Coast Guard. The pilotage waters of the Lower 
Mississippi River are described in a notice of designated areas 
published December 26, 1996 (61 FR 68090).
    Some commenters said crew size should be dictated by the size and 
needs of the vessel. One commenter said the vessel master must have the 
final say on the crew requirements. A towing company said it is 
important that the minimum manning requirements account for different 
vessel operations (e.g., crew of three for ship assist work in-harbor 
versus crew of six for offshore trips).
    While the master has a role in ensuring the proper manning of a 
vessel, the master must observe applicable law and regulations, and the 
manning specified by the Coast Guard on the vessel's COI when 
performing that role. We note that under Sec.  140.210, the master must 
ensure that adequate corrective action is taken when he or she 
encounters unsafe conditions. The COI issued by the Coast Guard will 
specify the minimum manning for the vessel under normal operating 
conditions and the master must adhere to the provisions of the COI. See 
Sec.  140.210(a)(1). The towing vessel master and the TSMS should 
identify when, and if, additional personnel are needed on board the 
towing vessel. During flood or low water conditions, for example, the 
master may specify that additional crew members are needed.
    We received some comments requesting that the Coast Guard clarify 
and resolve differences in language between Sec.  15.535 and language 
in the STCW Supplemental NPRM that proposed to amend Sec.  15.610.
    As noted above, the STCW final rule has been published, and we have 
amended the text in Sec.  15.535(c) to match the current Sec.  
15.610(b). There was a slight variation in wording between Sec.  
15.535(c) as originally proposed and Sec.  15.610(b).
    Further, our proposed Sec.  15.535(c) specified that the towing 
vessel ``be under the control of an officer who holds a first class 
pilot's license or endorsement for that route, or who meets'' 
requirements related to the type of barge being towed. The current 
Sec.  15.610(b) specifies that the towing vessel be under the control 
of an officer meeting that section's requirements for a towing vessel 
of 26 feet or more in length and that that officer hold ``a first-class 
pilot's endorsement for that route or MMC officer endorsement for the 
Western Rivers, or'' that the officer meets the requirements for a 
towing vessel of 26 feet or more in length and the requirements based 
on the type of barge being towed. Consistent with the commenters' 
recommendations, we have amended Sec.  15.535 to conform to the current 
version of Sec.  15.610.
    Also, because we added Sec.  15.535 to address vessels subject to 
subchapter M, we inserted a paragraph at the beginning of Sec.  15.610 
to limit that section to towing vessels not subject to subchapter M. 
Applicability exceptions in subchapter M explain that some towing 
vessels at least 8 meters in length will still be subject to Sec.  
15.610. We made necessary organizational changes to Sec.  15.610 to 
reflect our insertion of this new paragraph.
    An individual recommended that in addition to the towing vessel 
being

[[Page 40010]]

operated by a properly licensed master, our rule should require at 
least one crew member to be documented with preferably an ``Able 
Bodied'' seaman's rating. The commenter noted his marine work 
experience and seeing members of a construction crew assigned to handle 
the lines when a towing evolution was needed. He stated that the skills 
and knowledge of construction workers do not always overlap with those 
required of seamen.
    We did not propose the change suggested by this commenter and would 
want to receive comments before making the suggested change. But we are 
confident that the manning requirements in Sec.  15.535 and 
requirements in Sec.  140.210 for reporting and addressing unsafe 
conditions provide assurances that lines will be properly handled 
during towing evolutions. We have not made a change from the proposed 
rule based on this comment.
    We received one comment saying that our rulemaking seeks to address 
issues such as a ``man overboard'' situation, but such situations are 
innately linked to minimum safe manning of a vessel. The commenter 
asked how a licensed towing officer at the helm is expected to safely 
and successfully recover a single deckhand from the water should the 
deckhand go overboard during routine operations.
    We have addressed requirements for lifesaving equipment, 
arrangements, systems, and procedures on towing vessels in Section IV.K 
of this preamble, ``Lifesaving,'' and lifesaving regulations are 
located in part 141 of subchapter M. When specifying the minimum 
complement of officers and crew necessary for the safe operation of the 
vessel, the OCMI is called on to consider emergency situations such as 
a person overboard. See 46 CFR 15.501.
    One commenter pointed out that language used in Sec.  15.535 in the 
NPRM regarding an exception for certain towing vessels was eliminated 
by section 606 of the 2010 Act.
    As noted above in response to a comment addressed in section IV.B, 
section 606 of Public Law 111-281 did strike the paragraph in 46 U.S.C. 
8905 that exempted vessels of less than 200 gross tons ``engaged in the 
offshore mineral and oil industry if the vessel has offshore mineral 
and oil industry sites or equipment as its ultimate destination or 
place of departure'' from 46 U.S.C. 8904 requirements and regulations 
promulgated under 46 U.S.C. 8904. This statutory change was not 
reflected in our proposed rule. Accordingly, we made a conforming 
amendment to Sec.  15.535(b), which excludes certain vessels from the 
licensed-master-or-mate requirement, by deleting the reference to 
vessels engaged in the offshore mineral and oil industry. This 
amendment to Sec.  15.535(b), which now only exempts vessels engaged in 
assistance towing from the licensed-master-or-mate requirement, 
conforms this final rule to Public Law 111-281's amendment to 46 U.S.C. 
8905.
    One commenter expressed concern about the words ``not to include 
over time'' in the definition of ``day'' in existing 46 CFR 10.107 and 
that section's computation of service hours on vessels less than 100 
gross register tons (GRT). The commenter stated that work-hour abuses 
occur, especially on vessels of less than 100 GRT, because a day of 
work is considered 8 hours. Also, overtime is not counted toward sea 
service. The commenter recommends that this loophole be removed.
    In the proposed regulatory text of the NPRM, we did touch on 46 CFR 
chapter I, subchapter B, Merchant Marine Officers and Seamen, but we 
did not propose any changes to 46 CFR part 10, Merchant Mariner 
Credential, where 46 CFR 10.107 is located. Related to this comment, we 
note that Section 607 of the 2010 Act, which amended 46 U.S.C. by 
introducing additional logbook and entry requirements in 46 U.S.C. 
11304, included entries for the ``number of hours in service to the 
vessels of each seaman and each officer.'' We would need a separate 
rulemaking to fully implement section 607 of the 2010 Act, which 
involves hours of service; that rulemaking could apply to more than 
just towing vessels.
    We amended a regulation, 46 CFR 15.815(c), that requires a radar 
observer endorsement for masters or mates onboard an uninspected towing 
vessel 26 feet or longer by removing the word ``uninspected.'' When 
that regulation was issued, most towing vessels were uninspected, and 
Sec.  15.815(a) covered towing vessels 300 GRT or more that were 
inspected. Because most towing vessels 26 feet or longer will become 
inspected once this rule becomes effective, we are making this 
conforming amendment to 46 CFR 15.815(c). This change is consistent 
with our Sec.  15.815 towing-vessel specific enabling statute, 46 
U.S.C. 8904(a), which distinguishes towing vessels purely on length, 
not whether they are inspected or uninspected. Because Sec.  15.815(c) 
already requires this radar observers' endorsement on uninspected 
towing vessels, there is no anticipated cost associated with this 
change.

F. Certification/Definitions/Applicability (Part 136)

Applicability
    We received some comments supporting the Coast Guard's decision to 
defer consideration to a subsequent rulemaking of requirements for 
towing vessels less than 26 feet in length, towing vessels used solely 
for assistance towing, and work boats operating exclusively within a 
work site and performing intermittent towing within a work site. 
Several commenters expressed support for the concept of excepted 
vessels but felt that clarification is needed with regard to the range 
of fleet and harbor service operations that fall under this term. 
Others suggested that some aspects of the equipment requirements, like 
distress flares and additional lifebuoys, could be removed from the 
rule.
    In our definition of ``excepted vessel'' in Sec.  136.110, we make 
reference to harbor-assist, but we define that term in addition to 
``limited geographic area'' and we believe those definitions are 
sufficiently clear to identify the range of harbor service operations 
that fall under these terms. We had included a reference to a fleeting 
area as an example of a limited geographic area in our proposed 
definition of ``excepted vessel,'' but, as discussed below in this 
section (IV.F), we removed that and other examples for the separately 
defined term ``limited geographic area.'' Also, we amended the 
reference to vessels that may be included by the cognizant OCMI in this 
definition by identifying the requirements and reasons the OCMI must 
consider before treating a vessel as an excepted vessel for purposes of 
some or all of the requirements listed.
    The Coast Guard has not subjected excepted vessels to certain 
requirements in part 142 for fire protection equipment, and certain 
requirements for new vessels in part 143 for alarms and monitoring, 
general alarms, communication, fuel shutoff, additional fuel system 
requirements for existing vessels, and electrical power sources, 
generators, and motors, and electrical overcurrent protection. We have 
considered a commenter's request to also not require excepted vessels 
to comply with distress flare and additional lifebuoy requirements but 
decline to do so because the factors used to except these vessels do 
not reduce the need for flare and lifebuoy requirements.
    In Sec.  141.375, we have a more precise exception regarding 
distress flares and do not require that they be carried on vessels 
operating in a limited

[[Page 40011]]

geographic area on a short run limited to approximately 30 minutes away 
from the dock. Also, we have reviewed our lifebuoy requirements in 
Sec.  141.360 based on the request to not require additional lifebuoys 
of excepted vessels, but have not adopted this suggested change because 
some excepted vessels, for example, towing vessels used for response to 
an emergency, need to have on board the lifebuoys required under Sec.  
141.360. Also, we noted our use of the term ``excepted towing vessel,'' 
instead of ``excepted vessel,'' in part 143. We have clarified part 143 
by making all proposed references to ``excepted towing vessel,'' 
consistent with the term we defined, ``excepted vessel.''
    Some commenters did not agree with our exception of towing vessels 
less than 26 feet for several reasons, including smaller vessels being 
given an unfair competitive advantage, the fact that such vessels may 
be engaging in commercial work, and a concern about regulatory 
avoidance.
    Our exemption for towing vessels less than 26 feet in length is 
intended to provide for an incremental application of inspection status 
to the towing vessel fleet and is consistent with the recommendations 
of TSAC. We note here that we made edits in Sec.  136.105 to ensure 
that the exemptions in that section are clearly stated. Specifically 
regarding our meter approximation of 26 feet, we changed ``(8 meters)'' 
to the more precise approximation of ``(7.92 meters).'' Also we 
corrected the threshold for vessels subject to subchapter I.
    An individual noted that towing vessels should be measured end-to-
end at actual length, and another commenter suggested that the size of 
tow should be used to determine exempt vessels. Another individual 
recommended that the exemption should be based on a combination of 
length, displacement, and shaft horsepower in order to remove the 
incentive to use short, high-power tugs to circumvent Coast Guard 
inspections. A commenter suggested a clarification that towing vessels 
less than 26 feet in length are not exempt if they move barges carrying 
oil.
    For methods of measuring towing vessels, the Coast Guard sees no 
reason to deviate from the statutory standard in 46 U.S.C. 8904(a) 
which is reflected in 46 CFR 15.535 and 136.105: Length measured from 
end to end over the deck (excluding the sheer). We considered the 
suggestion of using size of tow or a combination of length, 
displacement, and shaft horsepower as a way to determine applicability, 
but we believe using the length of the towing vessels is a more 
manageable approach which--while not as direct--provides a measure of 
risk control.
    We agree that a change from the proposed rule is necessary to 
clarify that vessels less than 26 feet are not exempt from the 
requirements of this rulemaking when towing a barge carrying oil. In 
proposed Sec.  136.105, when identifying exceptions to applicability, 
we made clear that towing vessels less than 26 feet that push, pull, or 
haul a ``barge that is carrying dangerous or hazardous material'' would 
not be excluded from subchapter M applicability. In the NPRM, we did 
not define the term ``dangerous or hazardous material'' but in the 
preamble we did describe our limitation on the less-than-26-feet 
exemption by stating this rule does not apply to towing vessels less 
than 26 feet in length ``unless towing a barge carrying oil or other 
dangerous or combustible cargo in bulk.'' To make this intent clear in 
the regulatory text of the final rule, we have adopted the defined term 
``oil or hazardous material in bulk,'' to replace the term ``dangerous 
or hazardous material'' in Sec.  136.105(a).
    Also, to clarify that only one form of hazardous material needs be 
carried to trigger applicability, we changed ``materials'' to the 
singular, ``material,'' throughout the final rule. Also, we amended the 
definition of ``oil or hazardous material in bulk'' by inserting ``to 
carry cargoes'' in its reference to being certified under subchapters D 
or O to better reflect the nature of the certifications.
    Other companies supported the less-than-26-foot exception. One 
commenter acknowledged that the Coast Guard could address smaller 
towing vessels in a future rulemaking. An individual thought the 
exception should apply to even longer vessels (up to 32 or 40 feet in 
length) because such vessels are too small to do any serious towing, 
and a company agreed and stated that all its shipyard and harbor 
service vessels were 34 feet or longer.
    As noted above, the Coast Guard approach in transitioning the 
uninspected towing vessel fleet into an inspected status is to do so 
incrementally over time. Based on our analysis of risk and a specific 
recommendation provided by TSAC,\1\ we proposed that subchapter M apply 
to vessels 26 feet and above. This length standard has been used in 
various statutes to establish requirements for radiotelephones, 
automatic identification systems, electronic charts, and manning for 
towing vessels. See 33 U.S.C. 1203 and 1223a, and 46 U.S.C. 8904 and 
70114. We find no perfect length for measuring risk, but we believe 26 
feet is the best breakpoint to use at this time in our transitioning of 
the uninspected towing vessel fleet into an inspected fleet.
---------------------------------------------------------------------------

    \1\ ``Report of the Working Group on Towing Vessel Inspection,'' 
p. 6, submitted to TSAC on September 29, 2005.
---------------------------------------------------------------------------

    We received one comment supporting the exception for workboats that 
do not engage in commercial towing for hire but perform intermittent 
towing within a worksite. A contracting company agreed that increased 
equipment requirements are not needed for job site boats. Two 
individuals suggested that the exception should be simplified, such as 
by including a mileage limitation. A company recommended a slight 
expansion of the exception to cover workboats going to or from the 
worksite.
    The Coast Guard disagrees with the recommendation to include a 
mileage limitation or expand the exception, and believes the terms 
``worksite'' and ``workboat'' are adequately defined in Sec.  136.110. 
The OCMI will make determinations of the boundaries and limitations of 
worksites within the OCMI's zone. The OCMI will evaluate the unique 
operating conditions and hazards of the area and determine the risks 
and mitigating factors necessary to support such operations.
    A commenter requested that we treat workboats engaged in oil spill 
response activities as exempt, just as we exempt workboats operating in 
a worksite.
    The Coast Guard has already included an exception for towing 
vessels engaged in emergency or pollution response in our definition of 
``excepted vessels'' in Sec.  136.110. We do not intend to provide a 
general exemption to oil spill response vessels from these rules. 
Instead, the OCMI may designate a pollution response area as a worksite 
which would afford a towing vessel the opportunity to be exempt from 
subchapter M while it is operating exclusively in the worksite if it 
qualifies as a workboat under Sec.  136.105(a)(3).
    This is consistent with the Coast Guard's intent to provide 
inspection standards to certain vessels based on risk and consistent 
with the recommendations of TSAC. This rule exempts certain types of 
vessels from subchapter M, and relieves other types of vessels, 
excepted vessels, from certain equipment requirements due to the nature 
of their service. We have made no changes from the proposed rule based 
on this comment.
    Two commenters suggested adding language to our worksite exception 
in Sec.  136.105(a)(3) to include ``maneuvering a tank barge on and off 
of a drydock or

[[Page 40012]]

cleaning dock'' to the ``intermittent towing'' covered in the worksite; 
and others recommended that we amend our ``excepted vessel'' definition 
in Sec.  136.110 to include moving vessels on and off drydocks and to 
and from cleaning docks, or shifting vessels within a limited 
geographic area, or including a full range of activities commonly 
performed by towing vessels in a limited geographic area.
    The Coast Guard sees no need for these recommended changes. Our 
workboat exception in Sec.  136.105(a)(3) covers the activity the 
commenter requests we add. Also, our definition of ``excepted vessel'' 
in Sec.  136.110 includes towing vessels operating ``within a limited 
geographic area.'' Excepted vessels could include towing vessels moving 
vessels on and off drydocks and to and from cleaning docks. But we have 
left this determination to the discretion of the cognizant OCMI, to be 
made on a case-by-case basis.
    We received a very large number of comments, particularly from 
commenters in the American Waterways Operators (AWO) Responsible 
Carrier Program (RCP), that expressed the belief that the TSMS should 
be required for all towing companies and should not be optional. 
Proponents argued that the TSMS is flexible and scalable, would create 
consistency, and addresses human error, the leading cause of towing 
vessel accidents. Some of the commenters favored having a third-party 
audit option and conservation of Coast Guard resources. A maritime 
company stated that the savings accruing from a robust TSMS will far 
outweigh any associated cost of development and implementation. One 
company observed that a TSMS gives a company the ability to adjust its 
system through lessons learned and continuous improvement, rather than 
complying with a set of standards once a year. Commenters stated that 
the Coast Guard should not make the TSMS optional because of concern 
about costs; instead the Coast Guard should eliminate requirements that 
are not justified by risk analysis. One commenter warned, however, that 
a TSMS is not a substitute for an inspection.
    We received many other comments that supported retaining the option 
of inspection by the Coast Guard. Proponents favored the flexibility 
provided by having the option, the reduced administrative burden of the 
Coast Guard inspection, cost efficiency for small businesses, and the 
fact that the Coast Guard already has a successful inspection program. 
An association has favored a traditional Coast Guard inspection program 
for the towing industry. An individual noted that small companies 
cannot afford to create and implement a TSMS and would depend on the 
Coast Guard to provide yearly inspections and guidance. Other 
individuals and a State government recommended that the Coast Guard 
should develop a model TSMS that would be easy for small companies to 
adopt. Another individual opposed having optional provisions in a 
regulation. A commenter pointed out that current form CG-3752, 
Application for Inspection of U.S. Vessel, should be revised to add a 
block for indicating which option is being used for the towing vessel.
    As we noted in the NPRM (76 FR 49979), the NTSB and TSAC have 
strongly supported a TSMS, and the approach is supported by the 
International Safety Management (ISM) Code. The NTSB disagreed with our 
applicability exception for seagoing towing vessels of 300 gross tons 
or more subject to the provisions of subchapter I because currently 
under 33 CFR part 96 only vessels measuring more than 500 gross tons 
and operating on international voyages are required to have SMS and the 
subchapter M regulation does not apply to the 22 seagoing towing 
vessels of 300 gross tons or more already inspected in accordance with 
regulations for cargo and miscellaneous vessels in 46 CFR subchapter I. 
The NTSB encouraged the Coast Guard to extend the SMS requirement to 
these seagoing vessels by requiring SMS on all seagoing towing vessels 
of 300 gross tons or more.
    The Coast Guard believes the traditional annual inspection regime 
we offer as an option to all towing vessels subject to subchapter M 
will provide necessary measures to ensure compliance with subchapter M 
requirements and enable us to detect non-compliance.
    The Coast Guard notes the NTSB concerns and acknowledges that not 
all seagoing towing vessels subject to subchapter I are required to 
comply with SMS requirements in 33 CFR part 96, subpart B, for vessels 
on international voyages. That applicability threshold of the 500 gross 
tons reflects an international standard from the International 
Convention for the Safety of Life at Sea, 1974, as amended (SOLAS) for 
vessels subject to Chapter IX of SOLAS, Management of the Safe 
Operation of Ships. In general, the Coast Guard supports all towing 
vessels being subject to a robust and well-functioning safety 
management system. Should the Coast Guard decide to extend SMS 
requirements to all vessels subject to subchapter M, or to seagoing 
towing vessels of 300 gross tons or more that are subject to subchapter 
I, we would proceed with a separate rulemaking. We would look at 
accident data after this rule becomes effective before proposing such a 
rule.
    We are considering the suggestion that we amend form CG-3752, 
Application for Inspection of U.S. Vessel, to add a block to indicate 
which option the towing vessel owner or managing operator is using. For 
now, we recommend using the ``Other (Indicate)'' box--e.g., ``Towing 
Vessel (TSMS option)'' or ``Towing Vessel (CG Inspection option).''
    We received some comments from towing or dredging companies 
suggesting exemption from the entire rule for certain vessels, such as 
all existing vessels, vessels under 79 feet, vessels under 200 gross 
tons, or vessels operating on inland and harbor routes. One company 
argued that construction/dredge tugs on the Great Lakes should be 
considered for exceptions. Another company requested an exception for 
vessels that work as towing vessels less than 10 percent of the year. A 
small company with an 18-foot tow vessel and a 33-foot barge that 
carries less than 10,000 gallons of diesel requested an exception. Some 
commenters suggested that vessels used to move passenger barges should 
be specifically excluded. One company recommended that a committee 
should be formed to examine which regulatory provisions are appropriate 
for particular vessels.
    The Coast Guard does not believe that broad exemptions from the 
requirement of these rules would serve the intended goal of improving 
safety in the towing vessel industry. The Coast Guard seeks a balance 
between a tiered implementation of towing vessel safety rules to 
vessels with the greatest risk and a prudent exemption of applicability 
to towing vessels with less potential risk to life, property and the 
environment.
    One commenter suggested exemptions for towing vessels operating on 
inland and harbor routes not engaged in transporting petroleum 
products. In particular, they argued that the TSMS and towing vessel 
record (TVR) requirements should only apply to vessels that tow oil and 
hazardous material, or are over 79 feet and 2,000 HP.
    The Coast Guard disagrees. As we note in our earlier discussion of 
part 136 comments, the Coast Guard does not intend to create exemptions 
for all types of inland towing operations, or to provide exemptions for 
particular areas without cause. We note, however, that under Sec.  
136.230 the OCMI may consider

[[Page 40013]]

route-specific requirements of subchapter M when designating a 
permitted route.
    Regarding the TSMS requirement, it is optional. In this final rule, 
the only vessels required to maintain a TSMS are those that choose the 
TSMS option. A TSMS, however, may benefit every type of towing vessel 
regardless of its service routes, vessel length, or vessel horsepower. 
For more details on this, see the discussion in section IV.B and the RA 
for the final rule (in the docket). As for the TVR requirement, the 
vessel owner or managing operator has the option of maintaining it 
electronically or on paper, and for towing vessels with a TSMS, the 
required records may be maintained in another record specified by the 
TSMS. It is essential for maritime safety that data we require in Sec.  
140.915 be recorded. We discuss the TVR requirement, and the various 
forms it may take, in more detail in our discussion of part 140 
comments.
    We received one comment that favored applying the rule to vessels 
towing oil and providing harbor assist to large ships, applying a less 
costly system to other vessels, and clarifying exemptions. Many 
commenters agreed that rules designed for offshore or ocean routes or 
large rivers were not appropriate for vessels in canals, harbors, or 
shallow rivers. The commenters opposed a one size fits all approach, 
and noted that Congress intended different standards for various types 
of towing vessels. One of the commenters favored grandfathering 
existing vessels into compliance for as many of the requirements as 
practicable. Another commenter, however, noted that risks are similar 
for inland and harbor towing as for coastwise or ocean towing, and 
solutions, such as planning and testing, should be similar. A towing 
company opposed having more stringent rules for tank barge operators 
than for companies that haul dry cargo barges.
    The Coast Guard agrees that there are different characteristics, 
methods of operation, and nature of service of towing vessels that 
require unique application of requirements. The Coast Guard believes 
that the utilization of a TSMS allows the operator to tailor safety 
processes to the unique conditions in which the vessel and company 
operate. A TSMS is scalable, dynamic, and customized by the operator 
for the unique risks, challenges, and operating environments 
anticipated. Some hazards are universal to all vessels regardless of 
where they operate. Therefore, the Coast Guard believes that certain 
minimum standards are necessary to mitigate these risks and seeks to 
apply them to all towing vessels subject to this rule. The additional 
variations necessitated by the type and area of operation can be 
accommodated by a TSMS.
    An association questioned whether ``Lugger Tugs,'' towing vessels 
that carry cargo, would be inspected as towing vessels or as offshore 
supply vessels. One individual urged the Coast Guard to ensure 
consistency in regulatory enforcement and fairness for all vessels.
    The Coast Guard notes that towing vessels that carry cargo for 
hire, or conduct other regulated activities--such as carrying 
passengers for hire, would likely be subject to regulations contained 
in other subchapters. Vessels engaged in two (or more) separate 
regulated activities are referred to as being in ``dual (or multiple) 
service.'' Towing vessels that want to conduct activities other than 
just towing need to seek approval from the OCMI issuing the COI. The 
Coast Guard provides guidance to all OCMIs to help ensure consistency 
in regulatory enforcement and fairness for all vessels. In the example 
of a towing vessel carrying cargo, that vessel meets the definition for 
two vessel types and would have to meet additional requirements to 
carry cargo on the towing vessel. Numerous parameters, including vessel 
characteristics and the operations conducted by the vessel, would 
determine under which vessel type the vessel would be inspected.
    For clarification, we amended our description of ``public vessel'' 
in Sec.  136.105 to match the term defined in 46 U.S.C. 2101. We also 
point to the 46 U.S.C. 2101 definition for the meaning of the term in 
Sec. Sec.  2.01-7, 15.535, and 15.610 of this chapter.
Definitions
    We received several hundred comments suggesting edits, deletions, 
or additions to our proposed definitions in Sec.  136.110. The 
discussion of changes made to the individual terms is as follows:
``Accepted Safety Management System''
    We deleted our proposed definition of ``Accepted Safety Management 
System'' because we did not propose to use the term within the 
regulatory text of the NPRM and do not use it in this final rule.
''Audit''
    We received a suggested amendment of the first sentence in our 
definition of ``audit'' that would replace ``planned arrangements'' and 
``arrangements'' with ``TSMS.'' One commenter suggested deleting the 
phrase ``observing persons performing required tasks'' in paragraph 
(1)(iii) of the proposed definition of ``audit,'' because there is no 
definition for ``required task.''
    The Coast Guard partially agrees with the first comment. Not all 
towing vessels will operate in accordance with a TSMS. Under Sec.  
138.225, some vessels may meet TSMS requirements by complying with ISM 
Code requirements of 33 CFR part 96 or some other SMS that the Coast 
Guard has accepted and deemed to meet subchapter M TSMS requirements. 
Rather than adopting the suggested edit, we deleted ``planned 
arrangements'' in favor of ``requirements'' and have made clear what 
requirements we intend to be covered by our Sec.  136.110 definition of 
``audit'' by specifying ``TSMS or other applicable SMS planned 
arrangements.''
    In response to the ``required task'' comment, the Coast Guard has 
edited the definition of ``audit'' in Sec.  136.110 by replacing the 
term ``required tasks'' with ``specific tasks within their assigned 
duties,'' in paragraph (1)(iii) and ``specific tasks'' with ``their 
assigned duties'' in paragraph (1)(ii). We used the term ``duties'' 
which is used in Sec.  138.220(b)(2) to describe training for 
operational duties and duties associated with the execution of the 
TSMS.
''Authorized Classification Society''
    We received a comment from a classification society requesting that 
the Coast Guard delegate the inspection of towing vessels to authorized 
classification societies. In response, as we discuss in more detail in 
our TPO preamble section (IV.I), we have amended Sec.  139.110 to 
clarify the distinction between audits and surveys. For the purpose of 
audits, a recognized classification society meets the requirements of a 
TPO and may work as a third-party auditor. For the purpose of surveys, 
an authorized classification society meets the requirements of a TPO 
and may work as a third-party surveyor. Further, we have amended Sec.  
144.140 to include certain authorized classification societies as being 
qualified to conduct a verification of compliance with design 
standards. Therefore, we have incorporated the part 8 definition of 
``authorized classification society'' into this final rule.
``Buoyant Apparatus'' or ``Inflatable Buoyant Apparatus''
    We received five comments, primarily from maritime companies and 
professional associations, suggesting the addition of a definition for 
the terms ``buoyant apparatus'' and ``inflatable buoyant apparatus'' 
because the terms are not defined in the proposed part

[[Page 40014]]

141. One maritime company suggested the following text for the 
definition of ``buoyant apparatus'': ``Buoyant apparatus is flotation 
equipment (other than lifeboats, life rafts, and personal flotation 
devices) designed to support a specified number of persons in the 
water, and of such construction that it retains its shape and 
properties and requires no adjustment or preparation for use.'' The 
same commenter offered the following text for the definition of 
``inflatable buoyant apparatus'': ``Inflatable buoyant apparatus is 
flotation equipment that depends on inflated compartments for buoyancy 
and is designed to support a specified number of persons completely out 
of the water.''
    The Coast Guard does not agree that it is necessary to include 
definitions for commonly understood lifesaving apparatus in subchapter 
M. These terms are already defined in 46 CFR, part 160--Lifesaving 
Equipment, in Sec.  160.010-2. We did not make any changes from the 
proposed rule based on these comments.
``Class II Piping Systems''
    We deleted this definition as this term is no longer used within 
this subchapter.
``Cold Water''
    A maritime trade association had no objection to the proposed 
definition of ``cold water,'' and understood its application in Table 
141.305 regarding survival craft; however, the commenter was unaware of 
any deficiency in the survival craft currently in use and requested 
that only a single standard apply to the Great Lakes.
    The Coast Guard notes that the definition of cold water is 
consistent with other regulations and existing Coast Guard policy (NVIC 
7-91) lists the areas designated as cold water. While the Great Lakes 
are generally considered cold water, several lakes are not designated 
as cold water during certain months of the year. The Coast Guard 
believes that specifying all of the Great Lakes as all cold water, year 
round, would impose an unnecessary burden on those towing vessels which 
operate seasonally when certain lakes are not designated as cold water. 
However, this does not prevent a vessel owner or managing operator from 
voluntarily carrying the equipment required on cold water at all times.
``Consideration''
    We deleted this term as the proposed definition was identical to 46 
U.S.C. 2101 and the term was only used once in that context, so instead 
we added a reference to 46 U.S.C. 2101 directly to our definition of 
``assistance towing'' in Sec.  136.110.
``Crewmember''
    Two commenters felt that the term ``crewmember'' should be defined 
as an individual who is listed on Form CG 735(T): Master's Report of 
Seamen Shipped or Discharged, so as to avoid any misunderstanding 
related to vendors who are onboard for maintenance or repair.
    The Coast Guard has revised the definition in Sec.  136.110 to 
match an existing definition of ``crewmember'' in 46 CFR 16.105, 
paragraph (2)(iv) of which would exclude vendors who are onboard to 
conduct maintenance or repair work. Also, please note that the COI will 
list crewmembers required to be onboard and persons in addition to the 
crew that may be carried onboard the vessel.
``Disabled Vessel''
    One commenter noted that some dead ships can range up to 900 feet 
in length and suggested that we clarify our definition of ``disabled 
vessel'' and set some limit on a dead ship's size for purposes of 
assistance towing. We note that a dead ship is a ship without the 
benefit of mechanical or sail propulsion. The commenter's concern 
appears based on Sec.  136.105 excluding vessels used for assistance 
towing from subchapter M applicability. We defined ``assistance 
towing'' to mean ``towing a disabled vessel for consideration.''
    The Coast Guard disagrees about the need to amend our proposed 
definition of ``disabled vessel.'' We note that a dead ship would fit 
our definition if the vessel regularly operated under its own power but 
was temporarily disabled. The Coast Guard does not see a need to 
include a specific length criterion for dead ships in its definition of 
``disabled vessel'' because not all assistance towing vessels are the 
same length or horsepower and the local COTP would assess the size and 
number of towing vessels needed to assist a dead ship.
``Downstreaming''
    A maritime company suggested we insert ``attempting to land'' in 
place of ``landing'' in our proposed definition of ``downstreaming.'' 
The Coast Guard acknowledges that downstreaming includes unsuccessful 
as well as successful attempts to align with a barge or other object, 
but has replaced the word ``landing'' with the words ``in order to 
approach and land squarely on'' instead of the commenter's suggested 
words. Also, we amended the definition by replacing the limited 
reference to the ``end of the barge'' with ``a fleet, a dock, or 
another tow.'' Finally, we inserted the words ``with the current'' to 
describe downstreaming and to reflect the nature of our concern in 
Sec.  140.610(e) where we require all exterior openings at the main 
deck level to be closed when a towing vessel is downstreaming.
''Engine Room''
    In reviewing the definition of ``engine room'' in the NPRM, the 
Coast Guard decided the word ``area'' was too broad; accordingly, we 
have replaced ``area'' with ``space,'' which is commonly used and 
understood in the maritime industry to refer to a specific room (also 
see the definition for ``Accommodation space'' in Sec.  136.110).
``Element''
    After reviewing this definition, which as proposed, only applied to 
safety management systems, we decided to delete it as the term 
``element'' is also used within the subchapter with regard to surveys 
and audits. Additionally, whenever the term is used, its meaning is 
clear.
``Essential System''
    A company requested that we replace references to ``vessel'' with 
``towing vessel'' in our definition of ``essential system.'' Another 
commenter noted that the definition of ``essential systems'' is similar 
to the term ``critical systems'' in the ISM code, suggesting that the 
terms be aligned or at least cross-referenced for clarification. An 
association whose members trade on all five of the Great Lakes noted 
that the definition of ``essential system'' is very broad and needs to 
be scaled back to systems that are truly essential so as to help ensure 
consistent application, and that as written, it is difficult to 
identify a shipboard system other than galley equipment that is not 
essential.
    Regarding the first comment, the Coast Guard disagrees with the 
suggestion because this entire subchapter pertains to towing vessels, 
and we believe references to ``vessel'' in our definition of 
``essential system'' clearly refer to towing vessel. We agree it is 
important to distinguish ``vessel'' from ``towing vessel'' in the few 
contexts in subchapter M where it is necessary, but we do not view our 
definition of ``essential system'' as one of them. We made no change 
from the proposed rule based on this first comment. In response to the 
second comment, to better align our definition with critical systems in 
ISM code, we added language to include critical systems identified in a 
part 96-compliant SMS. As for scaling back

[[Page 40015]]

systems included, the Coast Guard disagrees. We believe that the 
definition of ``essential system'' accurately covers those systems that 
are required in subchapter M to ensure a vessel's survivability, 
maintain safe operation, control the vessel, or ensure safety of 
onboard personnel.
``Excepted Vessel''
    Many commenters, including an association and various towing 
companies, supported the concept of ``excepted vessel,'' under which 
towing vessels operating solely in fleeting and harbor services would 
not be required to meet certain equipment requirements in part 143. 
Several of the commenters suggested that the definition of ``excepted 
vessel'' should be clarified or expanded to specify activities such as 
moving vessels on and off drydocks or to and from cleaning docks. Also, 
commenters stated the definitions should encompass the full range of 
activities commonly performed by towing vessels in limited geographic 
areas or harbor assist service and that failure to do so will 
potentially endanger the economic viability of small to medium size 
harbor/fleeting companies and consequently, the small to medium size 
ports and industries they service. One towing company requested 
clarification of the meaning of ``solely,'' because towing vessels 
often engage in different types of towing operations throughout their 
life-spans. An individual recommended that the term ``harbor assist'' 
in the definition of ``excepted vessel'' should be replaced by 
``assistance towing'' to be consistent with the applicability exclusion 
paragraph in Sec.  136.105(a)(2)(i) or with ``recreational assist.'' 
Also a company pointed to the need to improve our definition of 
``excepted vessel'' in Sec.  136.110 specifically as it applies to 
harbor assist vessels, a common term that it noted was used for vessels 
that conduct ship assist activities helping larger vessels in and out 
of port. One towing company opposed the concept of excepted vessels and 
expressed the view that all towing vessels should meet the same 
requirements. Another company also opposed exempting fleeting or 
limited route vessels from the proposed provisions, because such 
vessels may operate in close proximity to chemical plants and barge 
fleets. The commenter warned that such vessels may have minimal safety 
standards and operators may modify their vessels to benefit from the 
proposed provisions. An individual provided examples of vessels that 
work in fleeting areas but also travel many miles away from their base 
of operations without proper equipment. One commenter pointed out that 
the example of a limited geographic area (``a fleeting area for barges 
or a commercial facility'') in the definition of ``excepted vessel'' 
conflicts with the proposed definition of ``limited geographic area.''
    The Coast Guard views the excepted vessel category as a valuable 
tool to more precisely tailor regulations. We have amended the 
definition of ``excepted vessel'' by removing the examples of limited 
geographic area activities. The term ``limited geographic area'' is 
defined in Sec.  136.110 and allows local COTP discretion to determine 
limited geographic areas for her or his zone. Further, we note that, in 
addition to certain system and equipment requirements in part 143, 
excepted vessels are also not subject to fire protection requirements 
in Sec. Sec.  142.315 through 142.330. In terms of clarifying the 
definition, we did change it to make it clear that excepted vessels are 
subject to subchapter M, but not to certain requirements in the 
subchapter. Accordingly, we changed ``exempted'' to ``excepted'' when 
describing action by the OCMI that would make a towing vessel excepted.
    As for the recommendation that we clarify or expand on the list of 
specific activities within limited geographic area and harbor assist 
service, the Coast Guard disagrees. Instead, we have removed the 
examples of activities within a limited geographic area in favor of 
leaving the discretion with the local COTP, as stated in the definition 
of limited geographic area, and not have what some may read as an 
exclusive list of examples in our definition of ``excepted vessel'' 
that references limited geographic area. However, additional guidance 
beyond this rule may be developed to help the industry and public 
understand how operating in a limited geographic area may impact the 
equipment requirements if they are an ``excepted vessel''. The 
definition of ``harbor-assist'' remains identical to the existing 
definition in 46 CFR 10.107. Further, the definition of ``excepted 
vessel'' also contains the provision for the cognizant OCMI to except 
vessels based on reasons submitted by the vessel owner or managing 
operator as to why the vessel does not need to meet certain system and 
equipment requirements in parts 142 and 143 for the safe operation of 
the vessel. We believe that the ability to except certain vessels from 
specific equipment carriage requirements provides relief from the 
potential economic burden on these vessel owners.
    As for clarifying the meaning of ``solely'' in our definition of 
``excepted vessel,'' in Sec.  136.110, the Coast Guard sees no need to 
do so. The definition says ``[u]sed solely,'' for any one or a 
combination of the services listed. Therefore, subchapter M provisions 
not required of excepted vessels would be required of a towing vessel 
subject to subchapter M whenever it is conducting towing operations not 
listed in the definition of ``excepted vessels,'' unless it has been 
excepted by the cognizant OCMI. When a vessel is exclusively used in 
one or more of the excepted activities it is not subject to certain 
provisions of Subchapter M. However, if the vessel engages in 
activities that are not excepted, then it may be subject to those 
provisions even if this activity only occurs intermittently.
    In the NPRM, we proposed a definition for harbor-assist that is 
identical to the existing definition in 46 CFR 10.107. To be excepted, 
a vessel would need to be subject to subchapter M, and in the 
applicability section, Sec.  136.105, we state that subchapter M is not 
applicable to towing vessels ``used for assistance towing,'' so we 
would not include ``assistance towing'' in activities for excepted 
vessels. We also exclude towing vessels engaged in towing recreational 
vessels for salvage, or transporting or assisting the navigation of 
recreational vessels within and between marinas and marina facilities, 
within a limited geographic area. Harbor assist and assistance towing 
are two separate and distinct operations, both of which we have defined 
in Sec.  136.110. We have made no changes from the proposed rule based 
on these comments.
    We have amended the definition of ``excepted vessel'' to remove the 
reference to ``restricted service'' and, as noted above, to remove 
examples from the limited geographic area sentence that may have been 
too narrowly focused and conflicting with the definition of limited 
geographic area.
``Excursion Party''
    One commenter suggested that the term ``excursion party'' be 
defined as ``a group visiting the vessel for no specific business 
purpose.''
    The Coast Guard added a definition for ``excursion party'' in this 
final rule; however we do not agree with the commenter's proposed 
definition. As addressed in Sec.  136.245, any personnel (business, 
personal, etc.) not authorized to be carried by the COI would be 
considered by the OCMI when issuing an excursion permit.
``Flammable Liquid''
    One commenter suggested that we define ``flammable liquid'' and 
``combustible liquid'' as they are

[[Page 40016]]

defined in 46 CFR 30.10-15 and 30.10-22.
    The Coast Guard partially agrees. The definitions in 46 CFR part 30 
apply specifically to equipment required on tankers. The Coast Guard 
believes that adding these definitions would not provide any additional 
clarification for these rather common terms used in our fire protection 
and machinery and electrical systems and equipment regulations in 46 
CFR parts 142 and 143. However, we did modify part 143 to reference 
part 30.
``Fleeting Area''
    We received comments from two maritime companies regarding our 
proposed definition of ``fleeting area'' in Sec.  136.110. One 
commenter suggested inserting the words ``or wait to load or unload 
cargo'' after ``where individual barges are moored or assembled to make 
a tow,'' and to insert ``towing'' before ``vessel'' when referencing 
another vessel that will transport the barges in the tow to various 
destinations.
    The Coast Guard agrees with the second recommendation, but not the 
first. The inclusion of the term ``towing'' to the description of 
``vessels'' makes the definition clearer. We disagree with the first 
recommendation to insert the words ``or wait to load or unload cargo'' 
because here we are defining ``fleeting area'' which is focused on 
making a tow, as opposed to ``limited geographic area'' which may cover 
more activities. Reflecting the definition of ``limited geographic 
area,'' we also inserted, ``as determined by the local Captain of the 
Port (COTP),'' after a reference to a limited geographic area in our 
``fleeting area'' definition.
``Fully Attended''
    We deleted the definition of ``fully attended'' because we did not 
use the term in this final rule, nor did we use the term within the 
regulatory text of the NPRM.
``Harbor-Assist''
    A maritime company suggested that for our definition of ``harbor-
assist,'' we add ``shift'' to ``dock, undock, moor, or unmoor,'' and 
tie the escort of a vessel with limited maneuverability to these 
actions by removing the disjunctive ``or'' we have placed between those 
activities, and to add two more activities at the end of the definition 
``to shift or tow barges within a limited geographic area; or to 
respond to an emergency situation or pollution event involving towing 
vessels, vessels with limited maneuverability, or barges.'' Another 
commenter agreed and also felt that the definition should include 
inland harbor and fleet vessels.
    The Coast Guard disagrees. Regarding the recommendation to delete 
``or'' and restrict both ``dock, undock, moor, shift, or unmoor,'' and 
``escorting'' to towing vessel actions involving a vessel with limited 
maneuverability, we do not see a need for this change to this 
definition, which we adopted word-for-word from 46 CFR 10.107. For a 
vessel to be escorted, the vessel needs some independent maneuvering 
capability, which is not be true of all vessels a towing vessel may 
dock, undock, moor, or unmoor. We do not need to add ``shift'' to the 
definition because we believe any shifting is already captured by the 
words ``maneuvers to dock, undock, moor, or unmoor a vessel.'' Also, 
there is no need to add shifting barges in a limited geographic area 
nor do we wish to add towing barges in a limited geographic area to 
this definition. While not self-propelled, a barge would be included in 
the definition's reference of a vessel, and we do not view harbor-
assist as encompassing the full range of activities covered by 
``towing.'' Finally, we do not see a need to add responding to an 
emergency situation or pollution event involving towing vessels, 
vessels with limited maneuverability, or barges to our definition of 
``harbor-assist.'' Both of these activities are already included within 
our ``excepted vessel'' definition. We have made no changes from the 
proposed rule based on these comments; our subchapter M ``harbor-
assist'' definition remains consistent with the 46 CFR 10.107 
definition.
``Horsepower''
    A professional association and private citizen expressed support 
for our proposed definition of ``horsepower'' which is that stated on 
the COI which reflects ``the sum of the manufacturer's listed brake 
horsepower for all installed propulsion engines.'' We made no changes 
from the proposed rule based on these comments.
``Independent''
    One commenter suggested revising or deleting the definition of 
``independent'' because it appears only in Sec. Sec.  143.300 and 
143.435.
    Our proposed definition of ``independent'' in Sec.  136.110 is and 
was intended to be focused on equipment. We agree that it is not the 
appropriate definition for the use of ``independent'' outside of part 
143, Machinery and Electrical Systems and Equipment. In response to 
this comment, we have removed the definition from Sec.  136.110 where 
it would have been applicable to all of subchapter M and have placed it 
in part 143's definition section, Sec.  143.115, where it is only 
applicable to that part. We believe the definition is useful as limited 
to that part and therefore, we have only restricted, and not deleted, 
the definition.
    We use the word ``independent'' in a different context when we 
describe TSMSs and TPOs, as in our definition of ``audit'' and ``TPO'' 
in Sec.  136.110, and Sec. Sec.  138.205(b)(4), 138.310(d)(4), 
139.115(b)(1) and 139.120(p). In that context we will use the common 
definition of the term--to be free from the influence, control, or 
determination of another or others.
''Inland Waters''
    One commenter suggested deleting the proposed definition for 
``inland waters'' because it is not defined in other 46 CFR and would 
be confusing when considering classes of vessels. The commenter felt 
that the terms ``Inland waters, excluding Western Rivers'' can be used 
instead.
    The Coast Guard disagrees. ``Inland waters'' is defined in 46 CFR 
10.107 and our subchapter M proposed definition aligns with that 
existing definition. To address the reach of this and other Sec.  
136.110 definitions, we have inserted the introductory text of ``As 
used in this subchapter'' in Sec.  136.110, which reflects our initial 
intent that definitions in that section have limited applicability. 
Also, in subchapter M we only use the term ``inland waters'' once, in 
the definition of ``Western Rivers,'' and do not view it as generating 
confusion regarding classes of vessels. We have made no changes from 
our proposed definition of ``inland waters'' based on this comment.
``International Voyage''
    We received comments from two commenters requesting that the 
proposed definition of ``international voyage'' not include Canadian 
waters that are transit waters between Alaska and other States. The 
commenters noted that towing vessels do not always make port calls in 
Canada during passage and are not considered international voyages and 
subject to SOLAS.
    The Coast Guard does not see a need to amend our definition of 
``international voyage.'' Under our definition, towing vessels 
transiting directly from a U.S. port in the contiguous 48 states to the 
state of Alaska or the state of Hawaii would not be considered on an 
international voyage for purposes of subchapter M because they would 
not be going to a port outside the United States.

[[Page 40017]]

''Lakes, Bays, and Sounds''
    We received two comments suggesting the proposed definition of the 
term ``lakes, bays, and sounds'' be clarified to state that the 
operations on Kentucky Lake are not to be included in the current 
definition of ``lakes, bays, and sounds.'' Another commenter suggested 
that the definition is too broad to include lakes, bays, and sounds in 
inland river systems, and should be revised to exempt lakes, bays, and 
sounds that are part of the inland or Western River systems.
    The Coast Guard uses the term ``lakes, bays, and sounds'' in Sec.  
136.230 as one of a number of major headings under which each area of 
operation--referred to as a route--is described on a towing vessel's 
COI. With the exception of ``rivers,'' ``Lakes, bays, and sounds,'' is 
the least severe of the routes. Our definition matches that used for 
small passenger vessels in subchapter K (46 CFR 114.400) and small 
passenger vessels in subchapter T (46 CFR 175.400). The Coast Guard 
does not intend to create exemptions for all types of inland towing 
operations, or to provide exemptions for particular areas without 
cause. We note, however, that under Sec.  136.230 the OCMI may consider 
route-specific requirements of subchapter M when designating a 
permitted route. We have not made a change from the proposed rule based 
on these comments.
``Limited Geographic Area''
    One commenter asked for further definition of the term ``limited 
geographic area.''
    Our definition of ``limited geographic area''--``a local area of 
operation, usually within a single harbor or port''--is intended to be 
flexible enough to reflect the wide range of local operations. The 
local COTP has the discretion to determine limited geographic areas for 
his or her COTP zone. We do use the term ``limited geographic area'' as 
a factor in our definition of ``excepted vessel,'' but we believe it is 
appropriate to not impose certain requirements, such as for additional 
fire-extinguishing equipment, on vessels we identify as excepted 
vessels, or impose less rigid lifesaving equipment requirements on 
vessels that operate in a limited geographic area. We assess excepted 
vessels and certain vessels operating in a limited geographic area as 
presenting a reduced risk with respect to certain subchapter M 
requirements.
``Major Conversion''
    One commenter requested that we change our definition of ``major 
conversion.'' First, the commenter would establish a threshold up front 
that all the factors discussed must meet--that changes result in 
``essentially a new towing vessel''--while also leaving that same 
standard in the last (``otherwise'') factor. Second, the commenter 
would move our reference to a determination by the Coast Guard to the 
end of the definition. And third, the commenter would limit the 
``substantially prolonging the life of the towing vessel'' factor by 
expressly excluding ``the replacement of propulsion engines'' from that 
factor.
    The Coast Guard agrees with the recommendation that we move our 
reference to a determination to the end of our definition of ``major 
conversion.'' This change makes our definition more consistent with the 
statutory definition in 46 U.S.C. 2101 (14a) and our existing 46 CFR 
28.50 definition in subchapter C for uninspected vessels. We also 
clarified that reference from vaguely stating ``as determined by the 
Coast Guard'' to ``as determined by the Commandant.'' This change 
better aligns the definition with the phrasing used in existing text.
    We received comments from professional associations, maritime 
companies, and other companies who expressed concern over the phrase 
``substantially prolongs the life of the vessel'' in the proposed 
definition of major conversion. Commenters felt that the definition 
should be clarified to explain that routine activities like maintenance 
or part replacement are not considered major conversions, but only 
those activities that would result in the converted vessel becoming a 
new vessel. Two commenters, a private citizen and maritime company, 
requested examples of what is considered a major conversion. Another 
maritime company suggested that the term, as it is currently proposed, 
would apply ``new vessel'' requirements to existing vessels, and 
discourages the maintenance of or investment in existing towing 
vessels.
    We see no reason to adopt the commenter's two other suggested 
changes that deviate from the statutory definition. The first change 
would introduce an unexplained redundancy and the second would 
expressly exclude the replacement of propulsion engines from 
consideration of actions that substantially prolongs the life of the 
vessel. As reflected above, based on these comments, we have revised 
our definition to make it consistent with existing definitions in 46 
U.S.C. 2101(14a) and 46 CFR 28.50 of subchapter C, and we did not adopt 
the commenters' two other suggested changes. The Coast Guard believes a 
replacement of propulsion engines is normally undertaken to prolong the 
service life of a vessel, and therefore fits the definition of ``major 
conversion.'' To match the wording in 46 CFR 28.50, we changed ``Coast 
Guard'' to ``Commandant'' and added part 28's definition of 
``Commandant'' to Sec.  136.110. Major Conversion determinations are 
made by the Coast Guard Marine Safety Center on a case-by-case basis.
``Major Non-Conformity''
    One commenter suggested the following text for the definition of 
``major non-conformity'' which specifically identifies deviations as 
being from the safety management system and replaces our reference to 
the lack of effective and systematic implementation of the TSMS as 
being included as a major non-conformity, to references to items that 
would be considered a more significant breakdown or failure of the SMS: 
``Major Non-Conformity means an identifiable deviation to the safety 
management system which poses a serious threat to personnel, vessel 
safety, or a serious risk to the environment; where a large number of 
non-conformities exist in an area or where similar non-conformities 
exist throughout the company or vessel then this demonstrates a more 
significant breakdown or failure of the safety management system.''
    The Coast Guard has simplified its definition of ``major non-
conformity'' to include the term ``non-conformity''; by referring to 
``non-conformity'', we are including a failure to conform to the SMS. 
Even though the definition in 33 CFR part 96, our regulations 
implementing SOLAS and ISM Code provisions for safety management 
systems, includes an example of a lack of effective and systematic 
implementation, we have deleted that language from the definition in 
Sec.  136.110. We did not agree with the suggested definition, which 
could be read as creating an additional standard for a ``more 
significant breakdown.''
``New Towing Vessel''
    One commenter suggested that we remove the following factor in our 
proposed definition of ``new towing vessel'': Towing vessels that 
underwent a major conversion initiated on or after the effective date 
of our final rule.
    The Coast Guard disagrees with this recommended change to our 
definition of ``new towing vessel.'' Standards for new vessels are 
sometimes set higher than for existing vessels as a means of ensuring 
improved safety standards over

[[Page 40018]]

time without imposing undue costs on existing vessels. If we left major 
conversions out of the definition of new vessels, then we would provide 
incentive for existing vessels to undergo major conversions to avoid 
having to meet new vessel standards. Granting existing vessels the 
status of being ``grandfathered'' is a valuable regulatory approach, 
but factoring major conversions into our definition of ``new vessels'' 
provides a means of controlling a potential abuse of ``grandfathered'' 
status and is consistent with other 46 CFR subchapters. We have not 
made any changes from the proposed rule based on this comment.
    However, upon further review of the definition, we determined that 
it should be amended for other reasons. As proposed, the definition was 
based on the date the vessel was contracted for or the date the keel 
was laid. More often than not, these will be two separate dates which 
could lead to confusion as to whether or not a vessel is a ``new towing 
vessel.'' We amended the definition to base the determination on the 
date the keel was laid or the vessel is at a similar stage of 
construction in order to account for those instances where a vessel 
might be built in a modular mode of construction. We also removed 
paragraph (3) of the definition regarding vessels built without a 
contract because we viewed it as unnecessary given our removal of a 
reference to a contract in paragraph (a).
    The second reason for amending the definition is to ensure that 
owners, designers, and builders have sufficient time to adapt and 
incorporate the requirements applicable to new vessels into the design 
and construction of a vessel. As proposed, the date for a new vessel 
was 30 days after the regulation publication date. In reviewing a 
commenter's request for more time to comply with the final rule, we 
concluded that 30 days is too short a time period. It would be very 
difficult and costly to make changes in line with the ``new vessel'' 
requirements in those instances where the design of a vessel is almost 
complete. We have determined that for smooth transition and 
implementation, an additional year is needed, and we amended the 
definition accordingly.
``Objective Evidence''
    One commenter recommended we add records of an approved third-party 
organization as another example in our definition of ``objective 
evidence'' in Sec.  136.110.
    The Coast Guard agrees with this suggested change and has amended 
the definition accordingly. We already list classification society 
reports as an example, and would consider reports or records from a TPO 
as a similarly appropriate example reflecting an independent 
assessment.
``Pressure Vessel''
    One commenter suggested we amend our definition of ``pressure 
vessel'' to simply refer to closed containers designed to hold gases, 
liquids or a combination at a pressure substantially different from 
ambient pressure--instead of just ``under pressure.'' Another commenter 
suggested adding the following text as a definition for ``heating 
boiler'': ``An enclosed steel or cast iron container that uses an 
energy source to heat water (or make steam) that is sent through heat 
radiating devices in the machinery space to heat a towing vessel.''
    The Coast Guard agrees with the comment regarding pressure being 
substantially different from ambient pressure and in response inserted 
the words ``greater than atmospheric pressure'' at the end of the 
definition. We also agreed with the need to incorporate language to 
include boilers so we broadened the definition of ``pressure vessel'' 
to include ``unfired'' and ``fired'' pressure vessels which incorporate 
boilers.
``Random Selection of a Representative Sampling''
    One commenter suggested the need for defining ``random selection of 
a representative sampling'' for better consistency in the auditing 
process.
    We do not agree that a specific definition is needed for ``random 
selection of a representative sampling.'' We feel that ``random 
selection of a representative sampling'' is a common safety management 
system and auditing term that should be recognized and understood by 
any ISO-9001-trained internal or external auditor. In a related 
external audit provision in Sec.  138.410(f), we removed a vague 
reference to samples having to be statistically valid.
``Recognized Classification Society''
    We shortened the definition of ``recognized classification 
society'' by focusing on the core of the definition: A classification 
society recognized by the Coast Guard in accordance with 46 CFR part 8.
``Recognized Hazardous Conditions''
    We deleted the definition of ``recognized hazardous conditions'' 
because we do not use the term in this final rule, nor did we propose 
to use it in the regulatory text of the NPRM.
``Rescue Boat''
    One commenter noted that ``skiff'' is referenced in Sec.  
140.420(d)(4), which contains a training requirement if the skiff is 
``listed as an item of emergency equipment to abandon ship or man 
overboard recovery'' and that ``rescue boat'' also appears in Sec.  
140.420. The commenter recommends that if a rescue boat is a separate 
craft from a skiff, as our use of the two terms in Sec.  140.420 
suggests, then we should define ``rescue boat'' in Sec.  136.110 in 
addition to having defined ``skiff'' there.
    The Coast Guard agrees with the recommendation that we add a 
definition of ``rescue boat'' to Sec.  136.110. We do consider a rescue 
boat as a separate craft from a skiff. We have added the same 
definition of ``rescue boat'' in Sec.  136.110 that appears in three 
existing Coast Guard regulations. This definition distinguishes the 
dedicated purpose of a rescue boat--to rescue persons in distress and 
to marshal survival craft--from the general nature of a skiff, a small 
auxiliary boat carried onboard a towing vessel that might be used in 
emergency situations.
``Replacement in Kind''
    We have added a new definition to Sec.  136.110 for the term 
``Replacement in kind'' which was undefined in the NPRM but appeared 
several times in part 143. ``Replacement in kind'' generally means 
replacing a failed component with the same component, or a part with 
the same technical specifications as the original design. Replacements 
in kind may normally be accomplished by the crew, or a shipyard, as 
part of routine maintenance or repairs, and may not require 
notification to the OCMI.
``Safety Management System''
    Two commenters recommended inserting the following 11 italicized 
words in our proposed definition of ``Safety Management System'':

    Safety Management System means a systematically structured and 
documented system enabling the owner or managing operator and towing 
vessel personnel to identify and manage interrelated process and 
effectively implement the owner or managing operator's safety and 
environmental protection policies and that is routinely exercised 
and audited in a way that ensures the policies and procedures are 
incorporated into the daily operation of the vessel and company.

    In addition, one commenter recommended replacing the word 
``audited'' with ``evaluated'' in the above definition.
    The Coast Guard partially agrees with the proposals to change this 
definition.

[[Page 40019]]

We have amended the definition by adopting a modified version of our 33 
CFR part 96 definition that identifies those enabled by the SMS and the 
purpose of the SMS with respect to subchapter M. We disagree with 
changing the term from ``audited'' to ``evaluated'' as an audit is a 
clearly defined and recognized activity with respect to safety 
management systems.
``Survey''
    One commenter suggested that the difference between ``audit'' and 
``survey'' needs to be clarified in Sec.  136.110, as well as with 
respect to the Coast Guard option under proposed Sec.  136.150 and the 
TSMS option under proposed Sec.  136.205. Another commenter noted that 
these two terms, in addition to ``inspection'' are used interchangeably 
in the NPRM, as are the words ``auditor, inspector, and surveyor.'' 
There were also comments about the need to clarify the frequency of 
audits, inspections, and surveys, and which ones may be conducted by 
third parties.
    The Coast Guard believes that our definitions of these two terms 
are clearly distinguishable. Our definition of ``survey'' in Sec.  
136.110 focuses on compliance with subchapter M and other authorities--
``an examination of the vessel, its systems and equipment to verify 
compliance with applicable regulations, statutes, conventions, and 
treaties.'' Our definition of ``audit'' in Sec.  136.110 is more 
focused on systems set up to ensure that compliance. Neither proposed 
Sec.  136.150, Annual and periodic inspections, nor proposed Sec.  
136.205, which describes the COI, refer to audits or surveys.
    Regarding the word ``inspection,'' we did not define that term 
which applies to all vessels subject to subchapter M because they are 
all ``subject to inspection'' under 46 U.S.C. 3301. In this rule, we 
primarily use the word ``inspection'' to distinguish a towing vessel 
that has selected the option of an annual inspection by the Coast Guard 
instead of a TSMS option under which surveys and audits are conducted. 
But regardless of the option selected, under proposed Sec. Sec.  
136.140 and 136.145 the Coast Guard would conduct inspections for 
certification on all vessels seeking to obtain or renew a COI. An 
inspection is similar to a survey in that both involve an examination 
of a vessel to determine whether it is in compliance with applicable 
regulations or other legal authorities. In reviewing proposed 
Sec. Sec.  136.140 and 136.145, however, we reorganized these 
requirements and moved then into subpart B, Certificate of Inspection, 
as Sec. Sec.  136.210 and 136.212.
    We believe this response should clarify what we mean by the use of 
these terms but knowing the frequency of these activities may also 
help. Section 137.200 identifies the frequency of inspections 
associated with the Coast Guard inspection option. For vessels under 
the TSMS option, external and internal surveys and audits are required. 
Sections 137.205 and 137.210, respectively, identify the frequency of 
surveys under the external and internal survey programs. Finally, 
Sec. Sec.  138.310 and 138.315, respectively, identify the frequency of 
external and internal audits.
``Third-Party Organization''
    We received comments suggesting the need to clarify or remove our 
proposed definition of ``third-party organization.'' The commenter 
suggested that the term is inconsistent with our repeated use of the 
proposed term ``approved third-party organization'' in part 139 and 
would be redundant if we adopted his recommendation to amend our 
proposed definition of ``approved third party'' to make it clear it 
only refers to TPOs. One commenter suggested converting our proposed 
definition of ``approved third party'' in Sec.  136.110 to a definition 
of ``approved third party organization'' and to add ``organization'' to 
the definition so the term ``means a third party organization approved 
by the Coast Guard in accordance with part 139 of this subchapter.''
    The Coast Guard agrees that our proposed definitions of the terms 
``approved third party'' (ATP) and ``third-party organization'' (TPO) 
may cause confusion, so we deleted the term ATP and modified any 
references to approved third-party surveyors or auditors to make clear 
that such surveyors or auditors would be from a third-party 
organization or TPO. Also, we deleted the word ``approved'' used in 
front of TPO because by definition, TPOs are approved. Our definition 
of third-party organization in this final rule makes it clear that the 
organization is approved by the Coast Guard to conduct independent 
verifications to assess whether TSMSs or towing vessels comply with 
applicable requirements contained in this subchapter. Also, we have 
amended Sec.  139.115(b) to make that approval process clearer and 
replaced a reference to an organization having to meet subchapter M 
requirements with one to expressly include the standard of meeting part 
139 requirements for TPOs.
    This comment also caused us to notice that our TPO definition needs 
to be amended to better reflect the work being done by the TPO. We 
added the words ``assess whether'' to the definition of ``TPO.''
``Tow''
    One company recommended that we define ``tow'' as a vessel or 
vessels being moved by a towing vessel in contrast to our proposed 
definition that identifies the towing vessel as being part of the tow 
which would also include one or more barges or a vessel not under its 
own power.
    The Coast Guard concurs with the need to clarify that tow refers to 
what the towing vessel is moving--be it another vessel, barge, or some 
other object. We have revised our definition to read ``Tow means the 
barge(s), vessel(s), or object(s) being pulled, pushed or hauled 
alongside a towing vessel.'' This is consistent with our use of the 
term as a noun in our rule (e.g., in Sec.  140.625, ``the movement of a 
towing vessel and its tow''). Reflecting this definition, in Sec.  
140.805 we added ``or objects'' to barges and vessels when describing 
what may make up a tow.
''Towing Safety Management System (TSMS)''
    On reviewing the comments, the Coast Guard decided to add a 
definition of TSMS in Sec.  136.110 rather than just rely on the 
information contained in part 138 on TSMS compliance.
''Towing Safety Management System (TSMS) Certificate''
    We received several comments suggesting two separate definitions of 
the TSMS certificates be added: One for the owner or managing operator 
and one for each of the towing vessels found to be in compliance with 
the TSMS.
    The Coast Guard has not defined ``TSMS certificate'' and does not 
agree that two separate definitions should be added or that a separate 
certificate for the company and the towing vessel needs to be issued. 
TSMS certificates are issued to the owners or managing operators and a 
list of vessels covered by the TSMS must be maintained, as described in 
Sec.  138.305.
``Travel Time''
    Four commenters, including maritime companies and a professional 
association, suggested deleting the proposed term ``travel time'' 
because it does not appear anywhere else in the regulation. One 
commenter suggested that the proposed term needs to be amended to 
clarify the application to daytime operators who commute back and forth 
to work, not travel to a large commercial tug/barge unit that operates 
like a self-propelled vessel. Conversely, other commenters suggested 
that the

[[Page 40020]]

definition should not include travel back and forth. One company 
asserted that if the travel time is not included, crewmembers that do 
not live in close proximity to work will use the majority of their 
hours traveling.
    The Coast Guard agrees that our definition of ``travel time'' 
should be deleted from the final rule because we do not use that term 
in subchapter M.
''Unsafe Condition''
    One commenter, citing Sec.  137.325(d), asked the Coast Guard to 
create a good definition of an ``unsafe condition'' that can be 
consistently applied by companies, auditors, and surveyors, as well as 
the Coast Guard.
    The Coast Guard agrees with the commenter's request and has added a 
definition of ``unsafe condition'' to Sec.  136.110, which includes 
observation of a major non-conformity on board a vessel.
``Unsafe Practice''
    One commenter suggested that in the definition of ``unsafe 
practice'' the list of items that may be subject to significant risk of 
harm be supplemented by adding ``and the vessel'' after ``property.''
    The Coast Guard disagrees. A vessel belongs to an organization or 
person and, therefore, is included by the word ``property.'' We made no 
changes from the proposed rule based on this comment, but recognizing 
it can be bad practice to do something even once, we inserted reference 
to a single action, in addition to a habitual or customary action.
``Western Rivers''
    We received several comments, mostly from maritime companies, 
regarding the proposed definition of ``Western Rivers.'' Several 
maritime companies suggested that the definition should be consistent 
with the one in 33 CFR 164.70, which is identical except for it adds 
waters specified by 33 CFR 89.27 ``and such other, similar waters as 
are designated by the COTP.'' Commenters also asked that waterways 
mentioned in 33 CFR 89.27 be included. It was suggested that the 
consistency in definitions will help avoid new regulations for those 
vessels operating on the Gulf Intracoastal Waterway. One commenter 
noted that the proposed definition of ``Western Rivers'' is 
inconsistent with the definition in the TSAC report and current 
regulations. A trade association believed the change in the definition 
for ``Western Rivers'' would increase the burden on mariners. A 
maritime company noted that the NPRM lacks a definition, or a route 
description in Sec.  136.230, that covers vessels operating in the 
Inland areas of the waterway system within the Sea Buoy system, which 
includes the Gulf Intracoastal Waterway. The commenter suggested that 
Western Rivers be defined to include those vessels operating within the 
Sea Buoy system.
    Based on these comments, the Coast Guard has decided to adopt the 
existing 33 CFR 164.70 definition of ``Western Rivers'' which applies 
to navigation safety regulations for towing vessels.
    This is similar to the definition TSAC used in its September 7, 
2006 report (USCG-2006-24412-0004). Their definition ended with ``and 
waters connecting or tributary thereto'' instead of referencing waters 
designated by the COTP. Waters specified by 33 CFR 89.25 and 89.27, for 
inland navigation rule purposes, include all of the connecting and 
tributary waters specified in TSAC's definition, and our addition of 
the 33 CFR 89.27 reference includes the Gulf Intracoastal Waterway in 
the definition. Also, making our definition consistent with the one in 
33 CFR 164.70 allows COTPs to designate similar waters.
    Multiple factors in 33 CFR 62.27 are considered in the positioning 
of safe water marks, which are also called ``sea buoys.'' These factors 
may cause them to be placed seaward or shoreward of demarcation lines. 
And, while each safe water mark has a plotted position in the Light 
List available via 33 CFR 72.05-10, unlike demarcation lines in 46 CFR 
part 7, there are no lines associated with safe water marks. Therefore, 
we have decided to use the term ``navigational demarcation lines'' 
currently used in 33 CFR 164.70.
``Workboat''
    One commenter suggested we amend our definition of ``workboat'' to 
include ``vessels undergoing cleaning or repair,'' besides equipment, 
as things that the workboat pushes, pulls, or hauls alongside within a 
worksite.
    The Coast Guard disagrees with the proposed change. However, we 
have amended the definition of ``workboat'' to remove the specific 
listing of things being towed. We believe that the revised definition 
of workboat and our definition of worksite--which already included a 
list of certain activities which we amended to reflect the movement of 
equipment but specifically excluded the movement of barges carrying oil 
or hazardous material--provide sufficient flexibility to the OCMI to 
cover operations not specifically listed.
``Worksite''
    One commenter suggested that we amend the definition ``worksite'' 
so all areas within which workboats are operated over short distances 
for dredging, construction, maintenance, or repair work, including 
shipyards, owner's yards, and lay-down areas used by marine 
construction projects, would not require OCMI designation as worksites. 
Other worksites may be specified by the OCMI. Further, a maritime 
company suggested adding the terms ``cleaning facilities, fleeting 
areas'' to the definition of ``worksite.''
    The Coast Guard disagrees with these recommendations. We believe it 
is appropriate for the cognizant OCMI to designate worksites based on 
the factors and activities listed and their possible impacts on other 
waterway users. Therefore, we have decided not to adopt the expanded 
definitions being suggested here. We have made no changes from the 
proposed rule based on these comments.
Options for Obtaining a Certificate of Inspection
    A commenter opposed the option of obtaining certification by annual 
Coast Guard inspections and recommended deletions of provisions in 
proposed Sec. Sec.  136.130, 136.140, 136.145, 136.150, 136.165, and 
136.170.
    The Coast Guard recognizes that some in the industry view the 
option for Coast Guard traditional inspections as not having a role in 
the future of the regulation of towing vessels. We believe that the 
development of and adherence to a TSMS that is tailored to a company's 
unique operations and that provides for an authoritative reference for 
all members of the organization improves safety for the company's 
vessels. As the TSAC Economic Analysis Working Group Report (USCG-2006-
24412-0007) stated, the costs to a small company to implement and 
maintain an SMS may be more difficult to absorb than it is for a large 
company. These regulations do not preclude any towing vessel company 
from adopting a safety management system. However, the structure of 
subchapter M provides towing vessel companies with flexibility in how 
to comply with this subchapter.
    With respect to the various sections mentioned by this commenter, 
we have made changes in this final rule. Proposed Sec.  136.130 has 
been revised and retitled to better depict the purpose of the options 
it presents for documenting compliance with the requirements of this 
subchapter and to specifically note that a Certificate of Inspection is 
obtained following a Coast Guard inspection. We have moved proposed 
Sec. Sec.  136.140 and 136.145 into subpart B of part 136--Certificate 
of Inspection--as amended Sec.  136.210 and

[[Page 40021]]

new Sec.  136.212. Also, we merged proposed Sec. Sec.  136.150 and 
136.165 into a new Sec.  137.200 to delineate the processes under the 
Coast Guard inspection option from the TSMS option processes in part 
137. The proposed part 137 had laid out the TSMS procedures but was 
silent on the Coast Guard option. Further, we redesignated and amended 
proposed Sec.  136.170 as new Sec.  136.202.
    A commenter requested an appeal process to permit the immediate 
review of an inspector's determinations.
    The Coast Guard notes that, as we proposed, the appeals process is 
described in Sec.  136.180. Further, this final rule contains 
amendments to 46 CFR part 1 that institutes a process for appealing the 
decisions of TPOs acting on behalf of the Coast Guard.
Requirements for Existing Vessels During Delayed Implementation
    In response to comments regarding the cost of requirements in parts 
140 through 144, and concern about being able to meet those 
requirements soon after the rule is make effective, we delayed 
implementation of nearly all requirements in parts 140 through 144 
until July 20, 2018. We made the rule effective July 20, 2016 so that 
the Coast Guard can begin to apply other subchapter M regulations to 
review applications from those seeking to become TPOs and to impose 
deadlines for towing vessels to decide which option to choose--TSMS or 
Coast Guard annual inspections. We added Sec.  136.172 to ensure that 
we do not leave a gap after the rule becomes effective but before most 
requirements in parts 140 through 144 are implemented.
    Section 136.172 requires existing towing vessels that will be 
subject to subchapter M to remain subject to Coast Guard regulations 
applicable to the vessel on July 19, 2016 until the earlier of two 
dates: July 20, 2018 or the date the vessel obtains a COI.
Subpart B Certificate of Inspection
    We received a comment on proposed Sec.  136.200(d) urging that 
provisions from Marine Safety Manual Volume II, Section B, Chapter I, 
referencing 46 U.S.C. 3314 and completing a foreign voyage, should be 
added to the rule.
    As reflected in Sec.  136.200(d), towing vessels issued a COI under 
subchapter M are fully afforded the foreign-voyage-completion 
provisions of 46 U.S.C. 3314, Expiration of Certificate of Inspection. 
We made no changes from the proposed rule based on this comment, but on 
reviewing Sec.  136.200, we decided to insert a reference to the COI 
phase-in period in proposed Sec.  136.170 (now Sec.  136.202) in 
paragraph (a). This insertion is intended to incorporate the date by 
which the vessel must obtain a COI and thereby limit the statement that 
the vessel may not operate without having a valid COI onboard to the 
period after that date. Based on this review, we deleted proposed Sec.  
136.225, because it was redundant with Sec.  136.200(c).
    A commenter observed that companies choosing the Coast Guard 
inspection option should not be given a longer period of time to obtain 
a COI than companies choosing the TSMS option.
    The Coast Guard agrees. We have amended, redesignated, and retitled 
the proposed Sec.  136.170, Compliance for the Coast Guard option, as 
Sec.  136.202, Certificate of Inspection phase-in period. This section 
now specifies when COIs are required for towing vessels subject to 
subchapter M regardless of the option selected. Also, we removed Sec.  
136.203 because it is no longer needed given our amendment to what is 
now Sec.  136.202.
    We received several comments on the phase-in process in proposed 
Sec.  136.203, Compliance for the TSMS option. Several commenters 
suggested that the requirements for a TSMS and inspection requirement 
be phased in to allow for the industry to understand the new 
requirements and identify any specific waivers that may be needed. One 
commenter favored making sure there is about the same amount of work to 
be done in each of the 5 years that make up an inspection cycle. 
Another commenter recommended a provision to extend the schedules in 
the event of a shortage of approved auditors or inspectors. A 
professional maritime association suggested that a phase-in approach 
will assist in the transition for vessel operators and auditors and 
reduce the strain on shipyards as they manage extensive drydocking that 
will occur while vessels await their inspections.
    The Coast Guard generally agrees with these concerns. As discussed 
in response to an earlier comment, the Coast Guard has amended the 
requirements in proposed Sec.  136.170 to set the same timetable for 
obtaining a COI regardless of which option the vessel owner or managing 
operator selects, and we have removed Sec.  136.203, which had a 
separate timetable for those selecting the TSMS option. The phased 
approach in Sec.  136.202 distributes the work load over a 6-year 
period from the effective date of this final rule. The Coast Guard has 
crafted this rule to phase in towing vessels over time for numerous 
reasons including spreading costs and workload over time. Section 
136.202 provides a broad phase-in period for companies that choose 
either the Coast Guard or TSMS compliance option. As we stated in the 
NPRM, it will be up to six years before some vessels subject to 
subchapter M will need to obtain a COI. However, we do not agree that 
we need to add a provision to extend the schedules more than we have 
done already in this final rule. We believe that there will be 
sufficient TPOs available within the new prescribed timeframes to 
conduct subchapter M audits and surveys. Similarly, the Coast Guard is 
preparing to have enough inspectors available to meet the demand for 
Coast Guard inspections within the new prescribed time frames.
    A maritime company offered a phase-in timeline that depends on 
separate certificates for a company and their vessels. The commenter 
suggested that within 2 years of the rule's effective date a third-
party would conduct an external management audit of a company and issue 
a Towing Company Safety Management System Certificate. Then during the 
following year, a third party would conduct external vessel audits of 
25 percent of company's fleet and issue each vessel a Towing Vessel 
Safety Management System Certificate. Similar steps would be taken in 
subsequent years until in the sixth year, when all vessels would have 
to obtain COIs.
    As we noted in response to another comment, we disagree with the 
suggestion that two certificates should be issued instead of one TSMS 
certificate. We therefore decline to adopt a schedule based on the 
issuance of separate certificates for a company and the company's 
vessels.
    In a submission to the docket, the National Transportation Safety 
Board requested the prompt publication of the final rule to avoid any 
further delay in regulating the safety of this largely unregulated 
sector of the commercial maritime industry. The same commenter felt 
that the proposed 6-year implementation period should be shortened.
    We received a comment from a towing company suggesting that a 
shorter compliance period be applied to those operators who have not 
previously participated in the Uninspected Towing Vessel Bridging 
Program. The same commenter expressed the importance of consistent 
application of the final rule to all vessel operators. The commenter 
explained that by allowing some operators to bypass the requirements 
market rates will be affected, which will have a serious effect on 
small operators.
    The Coast Guard concurs with the desire to publish this rule 
promptly and,

[[Page 40022]]

in general, to apply it consistently to all vessel operators subject to 
subchapter M. We have explained why certain requirements are only 
applicable to new towing vessels and why excepted vessels do not need 
to comply with certain requirements. We disagree with shortening the 
implementation period across the board or, specifically, for those 
companies that did not participate in the Uninspected Towing Vessel 
Bridging Program, because it was a voluntary program. We believe our 
implementation period is appropriate for this rule, which establishes 
both a safety management system option involving TPOs and new 
requirements for more than 5,000 towing vessels.
    We received a few comments on proposed Sec.  136.205, which 
identifies what the COI will describe. One commenter noted that minimum 
manning requirements in the COI, as required under this provision, 
should be allowed to be different for different types of towing 
vessels. Another commenter asked how ``minimum manning'' is to be 
determined. Another commenter requested allowing for multiple minimum 
manning standards depending on the route. A commenter suggested that 
this rulemaking should clarify the number of required crewmembers and 
allow the towing vessel to be operated by a single crewmember in 
certain circumstances.
    Existing laws and regulations specify minimum levels of manning for 
towing vessels. As stated in Sec.  140.205, manning regulations are 
contained in part 15 of this chapter and vessels must be manned in 
accordance with the case specific requirements included in the COI. As 
stated in 46 CFR 15.705, the minimum safe manning levels specified in a 
vessel's COI take into consideration routine maintenance requirements 
and the ability of the crew to perform all operational evolutions, 
including emergencies, as well as those functions which may be assigned 
to persons in watches. The OCMI is empowered to establish a level of 
manning for a vessel above the minimum levels prescribed by law and 
regulation, based on the vessel's nature of operations and other 
parameters, including route.
    One individual was unclear about whether proposed Sec.  136.140 
applied to those who have an approved TSMS, as well as those who choose 
the Coast Guard inspection option. One company asked for clarification 
of the sequence of events for COI issuance.
    As noted above, our proposed Sec.  136.140, Application for a 
Certificate of Inspection (COI), is incorporated into amended Sec.  
136.210 and applies to all vessels subject to subchapter M. Regardless 
of the inspection option chosen, the owner or managing operator must 
submit an application for inspection to the cognizant OCMI where the 
inspection will take place. As specified in Sec.  136.130(d), the 
application should indicate which option the owner or managing operator 
is selecting.
    We amended Sec.  136.210 to make it clear how and when to apply for 
the initial COI. In our proposed Sec.  136.140, we specified deadlines 
for renewing a COI, but not those for obtaining the initial COI. Our 
amended Sec.  136.210 identifies the application and scheduling 
deadlines for the initial COI and reflects the same application and 
scheduling lead times for renewing a COI: Submit the application at 
least 30 days before the vessel will undergo the initial inspection for 
certification, and schedule an inspection for the initial certification 
with the cognizant OCMI at least 3 months before the vessel is to 
undergo the inspection for certification. Amended Sec.  136.212 sets 
forth the process of receiving a Coast Guard inspection at least once 
every 5 years and for receiving a new COI after being inspected by the 
Coast Guard.
    We received one comment recommending that the last line of proposed 
Sec.  136.145(b), now redesignated as Sec.  136.212(b), which describes 
the nature of inspections, should specify that inspection of the 
vessel's pollution prevention systems and procedures should be in 
accordance with any Memorandum of Understanding (MOU) between the Coast 
Guard and the Environmental Protection Agency.
    The Coast Guard disagrees with this recommendation because we do 
not view the proposed amendment as either necessary or desirable. We 
believe that the current language that the ``inspector will also 
examine the vessel's pollution prevention systems and procedures'' is 
appropriate. An inspection involves an examination of a vessel to 
determine whether it is in compliance with applicable regulations or 
other legal authorities. There are existing pollution prevention 
regulations that would pertain to inspected towing vessels that are not 
covered by any Coast Guard MOU with the EPA. We have not made any 
changes in this final rule based on this comment.
    An individual and a company requested clarification of the 
inspection frequency in proposed Sec.  136.145. Two companies suggested 
that frequency and level of inspection should be accomplished on a risk 
basis.
    In this final rule, Sec.  136.145 was renamed Sec.  136.212 and 
states that towing vessels subject to subchapter M will be inspected at 
least once every 5 years. Towing vessels choosing the TSMS option would 
be subject to annual surveys between those inspections, while towing 
vessels choosing the Coast Guard Inspection option would be inspected 
annually. See Sec. Sec.  137.200, 137.205, and 137.210.
    A company expressed concern about whether the Coast Guard would 
have resources to hire a sufficient number of competent vessel 
inspectors for convenient scheduling for the company, including drydock 
scheduling.
    The Coast Guard is prepared for the estimated demand for annual 
inspection from owners and managing operators selecting the Coast Guard 
annual-inspection option. The Coast Guard will closely monitor the 
demand for inspections and make resource adjustments as necessary. 
However, based on our reassessment of Coast Guard resources, we have 
removed the option in proposed Sec.  136.105(b) for vessels not covered 
by subchapter M to request application of this part.
    Another company requested that the Coast Guard do everything 
possible to ensure that Coast Guard inspections and third-party audits 
or load line surveys are coordinated to prevent an undue burden on 
industry.
    The Coast Guard agrees there are benefits to coordinating audits, 
surveys, and inspections, and will attempt to do so. However, there may 
be times when coordination is not possible due to scheduling and 
operational constraints.
    An association asked that the Streamlined Inspection Program be 
added as an alternative inspection process.
    The Streamlined Inspection Program, available under 46 CFR part 8, 
is an available option to obtain a renewal of a COI. If using that 
option, the owner or managing operator must comply with the procedures 
identified in part 8. We do not need to add text to subchapter M for 
this part 8 option to be available to vessels subject to subchapter M.
    An individual suggested we eliminate the term ``uninspected towing 
vessel,'' because towing vessels might not be inspected currently for 
structural construction, but are regulated and are subject to Coast 
Guard rules for daily operation.
    The Coast Guard agrees that all towing vessels are regulated by the 
Coast Guard to some extent but are not necessarily inspected. We have 
chosen to continue to identify those towing vessels not subject to 
subchapter M, and that are subject to subchapter C, as uninspected 
towing vessels.

[[Page 40023]]

    We received several comments on proposed Sec.  136.210(b)(3)(i), 
which would require that an application for initial certification 
include objective evidence that the towing vessel's structure and 
stability comply with applicable requirements. Commenters recommended 
that for existing towing vessels without a stability letter, an audit 
report noting that the towing vessel is being maintained and operated 
in a manner that does not compromise its watertight integrity or 
stability should be sufficient to satisfy this requirement. Others 
contended that stability is not an issue on inland waterways, and that 
there should be no stability requirements for Western Rivers towing 
vessels.
    The Coast Guard has amended Sec.  136.210 to more clearly identify 
what the owner or managing operator needs to provide the Coast Guard 
for both the Coast Guard and TSMS options with the application for 
inspection. Note that for the TSMS option the application must now 
include objective evidence of having a TSMS compliant with part 138 and 
that the vessel meets the requirements of this subchapter.
    Structural requirements for existing vessels are addressed in Sec.  
144.200. To satisfy that regulation, if a vessel is not built, 
equipped, and maintained to conform to the rules of a recognized 
classification society appropriate for the intended service and routes, 
the applicant must provide evidence that the vessel has been both in 
satisfactory service insofar as structural adequacy is concerned and 
that the vessel does not cause its structure to be questioned by either 
the OCMI or TPO. Stability requirements for existing vessels are 
addressed in Sec.  144.300 and under this provision, for those vessels 
without a stability document, documentation of operating history--for 
example through audit reports--is one option to meet Sec.  144.300 
requirements.
    The Coast Guard believes that stability is a concern on any vessel, 
regardless of service or operating area. Towing vessels must be 
maintained and operated so the stability of the vessel is not 
compromised.
    Proposed Sec.  136.210(b)(5) (redesignated as Sec.  
136.210(a)(2)(ii)) would require a description of any modification to 
the vessel. Some commenters suggested that the provision should be 
limited to major or substantial modifications to the design and 
construction of the towing vessel.
    The Coast Guard disagrees with these suggestions. The Coast Guard 
needs to be aware of changes and modifications made to inspected 
vessels. We will use this information to determine if a single change 
or incremental changes made to a vessel over time will affect a 
vessel's suitability for its route or service. However, replacements in 
kind, as defined in this subchapter, are not considered modifications. 
We have made no changes from the proposed rule based on these comments, 
but we did clarify that a description of any modification is only 
necessary when renewing the COI.
    With respect to proposed Sec.  136.215, which describes the period 
of validity of a COI, we received two comments urging the Coast Guard 
to add language to the rule so that noncompliance with a TSMS would not 
immediately result in the invalidation of the COI.
    The Coast Guard acknowledges that Sec.  136.215 states that if the 
TSMS certificate expires or is revoked, then the towing vessel's COI 
becomes invalid. Non-conformities or major non-conformities found 
during surveys or audits do not automatically invalidate the TSMS or 
the COI. However, deficiencies or non-conformities that are egregious 
could result in the OCMI removing the COI from the vessel. Ultimately, 
the status of the COI is determined by the OCMI. Based on the extent of 
the deficiencies or non-conformities found during an inspection, 
survey, or audit, the OCMI has various opportunities to work with the 
company to bring the vessel into compliance without suspending or 
revoking the TSMS certificate as specified in Sec.  138.305.
    Commenters noted that proposed Sec.  136.220 would require the 
original COI to be framed under glass and posted onboard the towing 
vessel. We received many comments noting that this requirement is 
outdated in this electronic age. These commenters suggested that the 
provision should simply state that a current copy of the COI must be on 
the towing vessel and available for inspection. Some of them added that 
the original COIs should be kept in a central location.
    In paragraph (b) of Sec.  136.220 we provide the alternative of 
keeping the COI readily available onboard in a weathertight container. 
Our Sec.  136.220 implements 46 U.S.C. 3312, which requires that the 
COI be displayed on the vessel but allows for alternatives as we have 
provided in Sec.  136.220(b). We do consider an open boat as an example 
of when it is impracticable to post a COI, but we removed this example 
from the text of Sec.  136.220(b) to place more focus on the statutory 
language. We require the original COI to be on board, rather than a 
copy, because there is only one original and removal of the COI from 
the vessel is one means the OCMI uses to prevent the vessel from 
getting underway if it is unsafe for it to do so.
    We received one comment on proposed Sec.  136.230(a) noting that 
the route endorsements on COIs issued to towing vessels should be 
consistent with the route designations on the COIs of the tank barges 
being moved.
    The Coast Guard notes that routes on barges and towing vessels are 
not interdependent. The towing vessel and its tow is limited to the 
most restrictive route of the towing vessel or any vessel in the tow. 
The Coast Guard encourages the company to match route-appropriate 
barges and towing vessels. However, we made no changes from the 
proposed rule based on this comment.
    In reviewing Sec.  136.235, which covers Certificate of Inspection 
amendments, we saw the need to distinguish procedures for a vessel 
seeking a COI amendment based on which option the vessel selected. We 
amended Sec.  136.235 accordingly. We also added a provision stating 
that the OCMI may need to conduct an inspection before issuing an 
amended COI.
    We received a comment on proposed Sec.  136.235, suggesting that 
the term ``towing vessel'' should replace ``vessel'' in paragraphs (b) 
and (c)(2) of that section. This commenter also noted the same edit and 
other editorial changes for various sections throughout the proposed 
rule language.
    The Coast Guard disagrees that there is a need to change every use 
of the word ``vessel'' to ``towing vessel'' when we mean towing vessel. 
As with Sec.  136.235, where we initially use the term ``towing 
vessel,'' and it is clear from the context that our use of the word 
``vessel'' refers to towing vessel, we do not see a need to repeat 
``towing vessel.'' We have been careful to always use ``towing vessel'' 
when referring to a towing vessel in sections where we also use the 
term ``vessel'' to mean something other than the towing vessel--e.g., 
in our definition of ``bollard pull'' in Sec.  136.110.
    Proposed Sec.  136.240 addresses permission to proceed to another 
port for repairs. We received two comments expressing support for the 
provision. Another commenter suggested that the vessel should be able 
to proceed for repairs even if there is noncompliance with the COI.
    The Coast Guard notes that under Sec.  136.240, an owner or 
managing operator must notify the cognizant OCMI in whose zone the non-
compliance occurs or is discovered before the vessel proceeds and also 
must notify any other OCMI zones through which the vessel will transit, 
and that the cognizant OCMI may require

[[Page 40024]]

inspection of the vessel by a Coast Guard Marine Inspector or 
examination by a surveyor from a TPO prior to the vessel proceeding. We 
clarified Sec.  136.240(a), which we intended to apply only to vessels 
with a TSMS, as the TSMS may address the necessary conditions under 
which the vessel may safely proceed to another port for repair. 
Accordingly, we amended paragraph (a), made corresponding amendments to 
paragraph (b), and inserted headings for all three paragraphs in Sec.  
136.240.
    We received one comment that recommended changing ``another port'' 
to ``next port of call,'' in Sec.  136.240 and confining the conditions 
requiring a Permit to Proceed to situations that affect safety or 
seaworthiness. Other commenters noted that the master, not the owner or 
managing operator, should be the person deciding if the trip for 
repairs can be completed safely.
    The Coast Guard disagrees with these recommendations. The term 
``next port of call'' may be too restrictive and may undermine the 
authority of the OCMI or the vessel's master in determining where the 
vessel may safely proceed to be repaired. Regarding the last comment, 
we do list ``owner, managing operator, or master'' when specifying who 
must make a judgment that the trip can be completed safely. We believe 
Sec.  140.210(b) addresses the commenter's concerns by specifying that 
if the master believes it is unsafe for the vessel to proceed, he or 
she must not proceed until it is safe to do so. We have made no changes 
from the proposed rule based on these comments.
    One commenter stated that in Sec.  136.240 it appears that a 
company must notify the OCMI any time a vessel must be moved to 
accomplish a repair not specifically addressed in the TSMS. The 
commenter stated that to completely comply it seems that all 
possibilities must be addressed in the TSMS or the OCMI will be 
inundated with requests for a problem not involving seaworthiness. We 
do not believe the commenter's characterization is accurate.
    Companies using the TSMS have the opportunity to tailor their 
system to address conditions the company anticipates may occur that 
would cause the vessel not to be in compliance and the necessary 
conditions under which the vessel may safely proceed to another port 
for repair. Under Sec.  136.240(b), if the condition is not addressed 
in the TSMS, the owner, managing operator, or master can request 
permission to proceed from the cognizant OCMI in whose zone the non-
compliance occurs or is discovered. A Permit to Proceed would only be 
needed when a repair is needed and the vessel is no longer in 
compliance with its COI. Minor repairs that do not affect the safety of 
the vessel (including seaworthiness) or its machinery would most likely 
not be considered issues that would invalidate the COI, and therefore 
would not necessitate a Permit to Proceed. We have made no changes from 
the proposed rule based on this comment.
    Proposed Sec.  136.245 addresses permits to engage in an excursion. 
We received a comment pointing out that a permit to carry an excursion 
party is required when the towing vessel carries more persons than 
allowed by the COI, but under proposed Sec.  136.205, a COI indicates 
that minimum number of persons, not the maximum.
    The Coast Guard notes that Sec.  136.205 does not reflect all the 
information contained on the COI. The COI is a document issued under 46 
U.S.C. 3309 that is in a form prescribed by the Commandant. Currently, 
it lists the minimum number of crew, those in addition to crew, and the 
total persons allowed on board. We have amended our description of the 
COI in Sec.  136.205 to include ``total persons allowed onboard.'' 
Separately, and upon reviewing proposed Sec.  136.205 and a similar 
description in 46 CFR 2.01-5, we amended Sec.  136.205 to improve its 
description of a COI's listing of safety equipment and appliances 
required to be onboard. Also, in further reviewing Sec.  136.245 we saw 
the need to amend it to include the case where a vessel chooses the 
Coast Guard option or the TSMS does not address excursion parties.
    Several commenters expressed the opinion that having guests such as 
vessel owners, service technicians, auditors, trainers, or crew changes 
for other vessels should not require a special permit. Other commenters 
opposed the proposed requirement to give 48 hours' notice to the OCMI 
because the need for an excursion party, such as customers or vendors 
on a towing vessel to see a particular operation, will often arise 
spontaneously. One commenter was unclear where to obtain a permit. We 
received a comment requesting the addition of a provision to require 
the COI to identify the number of crewmembers and persons in addition 
to crewmembers allowed onboard, taking into account overnight 
accommodations, lifesaving equipment, etc.
    The Coast Guard has added definitions for ``excursion party'' and 
``persons in addition to the crew'' in Sec.  136.110. Vendors/customers 
carried onboard would not constitute an ``excursion party''; these 
individuals would be carried as ``persons in addition to crew'' as 
permitted by the COI. We also amended Sec.  136.210 so that it prompts 
owners and managing operators applying for an initial COI to include 
documentation on the number of persons in addition to the crew they 
would like the OCMI to include in the COI.
    We received one comment on the proposed requirement in Sec.  
136.250 for load lines for vessels operating outside the boundary line. 
The commenter questioned how the requirement applied to the Great 
Lakes, in which there are no boundary lines.
    The Coast Guard notes that boundary lines are identified in 46 CFR 
part 7 and that load line requirements for the Great Lakes are provided 
in 46 CFR part 45. We edited Sec.  136.250 to make it clearer that it 
applies to all towing vessels on the Great Lakes, and also reorganized 
Sec.  136.250 into a table for greater clarity.

G. Vessel Compliance (Part 137)

    We received numerous comments on part 137, and we made several 
changes to the overall structure and content of this part. In subpart A 
we removed the definitions section, as we have removed similar 
definition sections in other parts, because it simply noted that 
subchapter M definitions in Sec.  136.110 apply to the part. We also 
deleted proposed Sec.  137.115 because the substance of this provision 
is contained in Sec.  136.210.
    We received two comments on proposed Sec.  137.120, which describes 
responsibilities for compliance. One commenter supported the provision 
that the owner and managing operator are responsible for ensuring 
compliance and suggested that when deficiencies and non-conformities 
are identified during vessel inspections and TSMS audits and fines 
imposed against a company, those action letters should be addressed to 
the person described in Sec.  137.120, thereby ensuring the person at 
the top is fully aware of the vessel's conditional status.
    The Coast Guard concurs that Sec.  137.120 holds the owner and 
managing operator responsible for compliance with subchapter M and 
other applicable laws and regulations. It also specifies that non-
conformities and deficiencies must be corrected in a timely manner; we 
have deleted the stated purpose for this corrective action requirement 
because it was unnecessary regulatory text. We will consider the 
commenter's suggestion for where to send notification of non-compliance 
but see no need to change the regulations.

[[Page 40025]]

    Under Sec.  137.130(c), we leave discretion with the owner and 
operator to specify in the TSMS procedures for reporting and correcting 
non-conformities and deficiencies. We have reorganized Sec.  137.130 to 
make it easier to read and understand the requirements of the two 
programs for compliance under the TSMS option.
    Another commenter requested that standard forms be provided to 
assist small companies with compliance, and that the Coast Guard should 
provide guidelines to OCMIs for simple inspections of towing vessels 
operated by companies too small to have staff dedicated to regulatory 
compliance, and that the Coast Guard should provide standard forms 
similar to U.S. Army Corps of Engineers usage reports which can be 
submitted to the local sector OCMI.
    Regarding the second commenter, the Coast Guard does not plan to 
prepare a specific form, but we have prepared a Small Entities Guide 
(available in the docket) for this final rule and we do plan to provide 
guidance to OCMIs on implementing this rule. We will develop where 
necessary and appropriate inspection and compliance checklists, job 
aids, and guides for our OCMIs and make them available to the public. 
We made no changes from the proposed rule based on these comments.
    We removed Sec.  137.125 because it simply states that if a TSMS is 
applicable to the vessel it must have provisions for compliance with 
part 137. Section 137.125 is unnecessary because part 138 addresses 
what the TSMS must cover regarding all subchapter M requirements.
    The new structure of this part, specifically in subparts B and C, 
presents together the discussion of inspections and surveys conducted 
under the both Coast Guard and TSMS options. As mentioned in the 
previous section of the preamble, we moved the discussion of 
inspections under the Coast Guard option from proposed Sec. Sec.  
136.150 and 136.165 into subpart B of this part. We also added a Coast 
Guard option section in subpart C of this part. In subpart C, we 
rearranged the order to place the discussion of drydock intervals first 
and then describe the Coast Guard and TSMS options. In response to 
comments we changed the term ``periodic survey'' to ``external survey 
program'' and the term ``audit program'' to ``internal survey program'' 
throughout the rule, including in the headings for Sec. Sec.  137.205 
and 137.210. We also defined these terms in Sec.  136.110 and added a 
reference to them in Sec.  137.130.
    An individual disagreed with the Coast Guard's proposed 5-year 
inspection for vessels under TSMS. The commenter suggested that like 
vessels under SOLAS, an annual verification examination should be 
conducted.
    In the NPRM, we did state that at the vessel level, towing vessels 
operating under the TSMS option would receive audits and surveys by a 
TPO, in addition to the Coast Guard conducting compliance examinations 
at least once every 5 years, along with additional random compliance 
checks based on risk (76 FR 49978, Aug. 11, 2011). While some vessels 
operating under a TSMS may be inspected by the Coast Guard once a year, 
we do not feel that annual Coast Guard inspections are necessary given 
the audit and survey requirements for vessels with a TSMS, along with 
our oversight of that system.
    We received three comments objecting to the term ``seaworthiness'' 
proposed in Sec.  136.150(a)(4), which we have reorganized into Sec.  
137.200. They noted that the appropriate term, especially for Western 
River towing vessels that don't go to sea, is ``fit for the service for 
which it was intended'' or ``suitable for its intended route.'' A 
commenter noted that proposed Sec.  136.150(a)(2) (now Sec.  
137.200(b)) would require a more detailed inspection if an inspector 
finds deficiencies or determines a major change has occurred, and 
recommended we set up boundaries on the open-ended term 
``deficiencies,'' such as ``deficiencies of sufficient number or 
severity,'' and that we delete the ``major change'' provision.
    The Coast Guard partially agrees with these recommendations. We 
consider ``seaworthiness'' to be an appropriate term for considering 
the condition of the vessel and note that the term is used in the 
Riverman's Lexicon (Lehman), a noted publication specific to the 
Western Rivers. However, we have added a reference to fitness for route 
and/or service to further clarify the intent in the paragraphs where we 
use the term ``seaworthiness'': Sec. Sec.  137.200(d), 137.300(b), and 
137.335(a)(1).
    We define the term ``deficiency'' in Sec.  136.110 to mean ``a 
failure to meet minimum requirements of the vessel inspection laws or 
regulations,'' and we do consider it appropriate to call for a more 
detailed inspection if deficiencies or a major change to the vessel are 
found. A major change would include a major conversion but would also 
capture other changes such as changes that may affect the operational 
safety of the vessel or fitness for route or service.
    A commenter asked us what constitutes a ``visit'' as opposed to an 
``inspection'' or an ``audit.''
    The Coast Guard may engage in visits to TPOs, as discussed in Sec.  
139.160, to ensure compliance with this rule. The Coast Guard notes 
that in the preamble of the NPRM we stated that, as part of our 
oversight of those organizations, we would conduct random oversight 
visits to the offices of TPOs that conduct TSMS audits and surveys. The 
Coast Guard also clarifies the procedures for such visits. The Coast 
Guard will provide notice to the employer 48 hours in advance of any 
site visit, unless the visit is in response to a complaint or other 
evidence of regulatory non-compliance (see Sec.  139.160). In response 
to an earlier comment above, we have discussed the distinction between 
inspections and audits. We have made no changes from the proposed rule 
based on this comment.
    One commenter expressed the opinion that annual and periodic Coast 
Guard inspections under proposed Sec.  136.150 would overly tax the 
system and not effectively utilize Coast Guard inspection talent.
    On page 32 of our Preliminary Regulatory Analysis and Initial 
Regulatory Flexibility Analysis (USCG-2006-24412-0002) we assumed that 
1,340 towing vessels from small companies with fleets of five or fewer 
vessels would select the Coast Guard annual-inspection option. Based on 
the many comments submitted about the benefits of a TSMS, we still 
anticipate that many owners and operators of towing vessels, 
particularly those from companies with large fleets, will select the 
TSMS option. The Coast Guard will closely monitor the demand for 
inspections and will make resource adjustments as necessary.
    With respect to the periodic survey provision in proposed Sec.  
137.205, we received one comment favoring an audit by a third party 
every 3 years rather than every year.
    The Coast Guard disagrees with this recommendation. We believe that 
3-year intervals would allow unsafe conditions and other problems to go 
undetected for too long. The annual compliance activities are 
consistent with other classes of inspected vessels including those that 
implement other safety management systems. To clarify when the annual 
survey under Sec.  137.205 must be conducted, we amended Sec.  136.110 
by adding a definition of ``anniversary date'' tied to the expiration 
date of the COI or TSMS certificate and we amended Sec.  137.205(a)(3) 
by referring to the COI's anniversary date. We also amended other 
sections that referenced

[[Page 40026]]

anniversary issuance date to read ``anniversary date.''
    We received one comment asking whether participation in an ISM 
program and issuance of a vessel's Safety Management certificate would 
meet the requirements in proposed Sec.  137.210, which is now titled 
Internal survey program. Section 138.225 clearly states that ISM Code 
compliance meets the safety management requirements in this subchapter. 
To clarify our reference in Sec.  138.225 to such vessels being deemed 
in compliance with ``these'' requirements, we amended Sec.  138.225(a) 
in this final rule to replace ``these requirements'' with ``TSMS-
related requirements in this subchapter.'' This clarifying edit is 
consistent with our statement in the NPRM preamble that the Coast Guard 
is proposing to accept compliance with the ISM Code, an internationally 
mandated safety management system for vessels subject to the SOLAS, as 
satisfying TSMS-related requirements. We implemented the ISM Code 
through regulations in 33 CFR part 96 and view the processes and 
procedures in place for compliance with the ISM Code as sufficient to 
ensure that towing vessels comply with TSMS-related requirements in 
subchapter M.
    This commenter also stated that proposed paragraph (e) of Sec.  
137.210 appeared to indicate the audit can be conducted by the 
operating company since the OCMI may require the attendance of an 
approved third party. He asks if our intent is to allow the operator to 
conduct these audits in lieu of periodic (annual) audits by a third 
party.
    Yes, it was our intent, which is reflected in this final rule, to 
allow operators to conduct some surveys and audits. We believe the 
commenter meant to reference paragraph (e) of Sec.  137.215. Section 
137.215 deals with conducting surveys and its paragraph (e) states that 
the OCMI may require the attendance of an approved third party ``to 
assist with verifying compliance with this part.'' We deleted Sec.  
137.210(c) to remove the requirement that a towing vessel must 
successfully complete an initial audit by a TPO before it may be placed 
into an internal survey program. Section 137.210 contains the 
provisions that allow for owners and managing operators to conduct 
annual surveys under the internal survey program. For the purposes of 
auditing under the TSMS option, there is also an internal audit program 
described in part 138 that allows the owner or managing operator to 
conduct annual internal management audits. We note that we have amended 
Sec.  137.210 by adding paragraph (a)(8) requiring that the TSMS 
contain procedures for assigning personnel to conduct surveys.
    We received several additional comments on the provisions in 
proposed Sec.  137.210. A few commenters suggested that ``audit 
program'' should be changed to ``program of continuous assessment'' and 
that the requirement in proposed paragraph (b) for timing of the 
surveys should provide that surveys may be conducted within 3 months of 
the anniversary date of the previous survey.
    Section 137.210(b) specifies that the interval between successive 
surveys of any item must not exceed 1 year. The words ``unless 
otherwise prescribed'' at the end of that paragraph modify the 
reference to not being required to survey items as one event. The 
internal survey program allows the owner or managing operator to assess 
the required items through a series of surveys, resulting in maximum 
flexibility in conducting vessel operations while fulfilling regulatory 
requirements. We want to preserve the flexibility afforded to the owner 
or managing operator that was intended by the continuous survey aspect 
of the internal survey program, and view the 1-year-from-successive-
survey requirement as the best means of assuring that required surveys 
under this flexible system are conducted. Therefore, we did not adopt 
the commenter's suggestion to amend Sec.  137.210 to require that 
surveys be conducted within 3 months of the anniversary date of the 
previous survey.
    One commenter recommended that proposed Sec.  137.210(a)(3) on 
identification of items that need repairs should allow for the issuance 
of Form CG-835 deficiency tickets.
    The Coast Guard agrees that the list of items for inspection and 
repair should include any existing deficiencies listed by the Coast 
Guard on Form CG-835, Notice of Merchant Marine Inspection 
Requirements. We have amended Sec.  137.210(a)(3) accordingly, and also 
added these related items: noted survey deficiencies, non-conformities, 
and other corrective action reports.
    Noting actions listed in proposed Sec.  137.210(d) (now Sec.  
137.212), which explains the OCMI's authority to require audits, 
surveys, and removal from the TSMS option, one commenter called for the 
Coast Guard to establish and use an industry advisory committee for 
each OCMI to advise him or her based on impartial industry knowledge. 
Another commenter recommended peer review to verify the quality of work 
performed by auditors.
    The Coast Guard disagrees with the suggestion that we establish and 
use an advisory committee for each OCMI. The Coast Guard has 
established requirements for auditors to ensure the competency of 
auditors in TPOs at 46 CFR 139.125 and 139.130. The Coast Guard retains 
oversight and administrative control of TPOs and through them, their 
auditors. See 46 CFR 139.135, 139.145, 139.150, and 139.160. We do not 
see the need for an additional level of review of their work. We 
developed these rules in coordination and consultation with TSAC, a 
Federal Advisory Committee whose members are appointed by the Secretary 
of Homeland Security to advise, consult with, and make recommendations 
to the Secretary on matters relating to shallow-draft inland and 
coastal waterway navigation and towing safety. Further, OCMIs work with 
Harbor Operations Committees and conduct regular meetings with port 
stakeholders and other industry representatives at the Sector level to 
discuss maritime issues, including those related to towing vessels. We 
made no changes from the proposed rule based on this comment, but we 
did clarify the reference to a ``change in ownership'' in proposed 
Sec.  139.125(c)(4) (now Sec.  139.125(d)(4)) that would cause an 
approval for a TPO to expire by inserting the words ``as defined in 
Sec.  136.110'' after the term.
    One commenter expressed concern about a lack of qualification 
requirements for the individual doing the surveys under the Sec.  
137.210 internal survey program, beyond those written into the TSMS. He 
recommended that the rule require the individual conducting surveys 
under Sec.  137.210 to have comparable qualifications to the third-
party surveyor.
    The Coast Guard has amended Sec.  137.210 by adding paragraph 
(a)(8) requiring that the TSMS contain procedures for assigning 
personnel to conduct surveys. As suggested by the commenter, under 
Sec.  138.220(c)(1) survey requirements must be specified in the TSMS. 
We have amended Sec.  138.220(c)(1) to make it clear that the TSMS must 
list the minimum qualifications of a surveyor if the surveyor is not 
from a TPO. We also removed Sec.  138.220(c)(3) and (e) because their 
proposed requirements are covered in elsewhere in Sec.  138.220.
    We received two comments on proposed Sec.  137.215, which describes 
the general conduct of a survey. One commenter noted that proposed 
paragraph (b)(3) would require observation of drills and training, but 
periodic surveys are typically performed while the towing vessel is in 
drydock or on a railway, and crews are generally not on board.

[[Page 40027]]

    The Coast Guard disagrees with the commenter's premise that 
periodic surveys under this subchapter will take place in a dry dock. 
At least portions of surveys under Sec.  137.215 will require that the 
vessel is dockside or underway to complete adequate operational 
assessment of equipment contained in the scope of Sec.  137.220.
    However, the Coast Guard agrees with the commenter that a surveyor 
would not traditionally be expected to observe the performance of a 
drill by the crew. We have amended Sec.  137.215 to reflect that the 
surveyor would focus on the vessel's structural, electrical, and 
mechanical systems, and equipment, including those used in drills--for 
example, davits, cranes, pumps, and lifesaving equipment. These 
functions could be performed while in drydock or without the crew 
present. It is the auditor who will focus on the operational 
performance of the crew to assess the competency in the performance of 
the assigned roles. For such an audit, the crew must be present and the 
vessel must be ready to demonstrate the performance upon request. The 
Coast Guard has amended Sec. Sec.  138.405(d) and 138.410(c), conduct 
of internal and external audits, assigning auditors the responsibility 
to witness drills.
    Another commenter requested a change to proposed paragraph Sec.  
137.215(c) which he felt created an unnecessary loophole. He 
recommended deleting it or revising it to read: ``While all the items 
listed in Sec.  137.200 must be surveyed for all vessels regardless of 
their condition, vessels and equipment found to be in poor condition 
may be required to undergo more stringent examinations in order to 
satisfy the attending surveyor.''
    The Coast Guard agrees that Sec.  137.215(c) should be amended to 
address this concern. We added language to Sec.  137.215(c) to ensure 
that survey standards in Sec.  137.215 are met and to require an 
expanded examination by the surveyor when he or she finds multiple 
deficiencies indicative of systematic failures. Regarding the items to 
be surveyed, Sec.  137.215(b) clearly states that the survey must 
address all items in Sec.  137.220.
    We received several comments on the scope of surveys in proposed 
Sec.  137.220. Some of the commenters focused on three requested 
changes: Clarification that gas-freeing prior to entry into confined 
spaces, such as fuel tanks, is not required; allowing verification of 
drills to be done using a review of documentation; and limiting the 
inspection of watertight doors to those that were required to be 
installed.
    As discussed in Sec.  137.330(b), fuel tanks need not be cleaned 
out and internally examined if the general condition of the tanks is 
determined to be satisfactory by external examinations. While the Coast 
Guard does not agree that crew competency can be verified by just 
reviewing records of required training and drills, we have removed the 
requirement for witnessing drills from the survey portion of the rule 
and have moved it to the audit requirements in Sec. Sec.  138.405 and 
138.410. Any watertight fittings that crews rely on for watertight 
integrity and vessel safety should be operational and subject to 
survey.
    One commenter noted that Sec.  137.220 should be amended to clarify 
that a topside exam can be conducted in segments and need not be done 
as a discrete event.
    Section 137.220 describes the scope of the survey which would apply 
under either the Sec.  137.205 or Sec.  137.210 program. For those 
choosing the Sec.  137.210 internal survey program to demonstrate 
vessel compliance, the Coast Guard makes it clear in Sec.  137.210(b) 
that the owner or managing operator is not required to survey the items 
as described in Sec.  137.220 as one event, but may survey items on a 
schedule over time, provided that the interval between successive 
surveys of any item does not exceed 1 year, unless otherwise 
prescribed. The Coast Guard believes that Sec.  137.210(b) provides 
clear guidance that an owner or managing operator of a towing vessel 
may select to have surveys done during multiple events. In contrast, 
the Sec.  137.205 external survey program calls for one event, an 
annual survey, and not successive surveys to survey the items described 
in Sec.  137.220. The Coast Guard has not made any changes from the 
proposed rule in response to this comment.
    Another commenter recommended that we eliminate the term ``rescue 
boat'' from the rule, which we used in proposed Sec.  137.220(g)(6) 
when identifying the scope of items to be examined and also in crew 
safety regulations in part 140 of the NPRM. He notes this change would 
avoid confusion between the terms ``skiff,'' ``survival craft,'' and 
``rescue boat.''
    The Coast Guard agrees that the use of the term ``rescue boat'' in 
this rule could cause confusion. We did not propose that subchapter M 
require towing vessels to carry rescue boats, so to avoid confusion, we 
have removed the references to rescue boats in Sec. Sec.  137.220 and 
140.405. We did, however, leave instruction and drill requirements in 
Sec.  140.420(d)(4) for launching and using a rescue boat if a towing 
vessel has one installed, and have defined rescue boat as described 
earlier in this preamble.
    One commenter objected to a Sec.  137.220(g) requirement for towing 
vessels to conduct a man-overboard drill, simulated under emergency 
conditions. The commenter noted that towing vessels on the Great Lakes 
should not have to comply with standards not applied to ``self-
propelled lakers'', that is, other self-propelled vessels, on the Great 
Lakes.
    The Coast Guard disagrees and did not make a change from the 
proposed rule based on this comment. We seek to promote safe vessel 
operations for all towing vessels and we have casualty data that 
indicates that falls overboard is one of the main contributing factors 
to crew member fatalities in this industry. As detailed in Sec.  
136.105, the Coast Guard has provided a number of exceptions for towing 
vessels based on the known risks involved in their specific operation. 
The Coast Guard has declined to provide blanket exemptions for entire 
operating areas such as lakes, bays and sounds, rivers, or as the 
commenter suggests, the Great Lakes. The Coast Guard has evaluated the 
hazards of towing vessel operations in each of these particular areas 
and determined that the application of these regulations to certain 
towing vessel operations in each of these areas would improve safety to 
life, property and the environment.
    In addition, noting the language currently in 33 CFR 164.01(b) and 
the ``33 CFR part 164, if applicable'' language in proposed Sec.  
137.220(j)(5), a commenter raised concerns about determining when and 
whether a given towing vessel is subject to 33 CFR part 164 navigation 
safety regulations.
    We did not propose to amend 33 CFR part 164, and neither Sec.  
164.01 nor other sections in that part use ``inspected'' or 
``uninspected'' as criteria for applicability, so this rule does not 
alter the applicability of 33 CFR part 164 for towing vessels. To see 
what requirements in 33 CFR part 164 may apply to a given towing 
vessel, one needs to review all of Sec.  164.01, not just paragraph (b) 
which is focused on towing vessels. For example, Sec.  164.01(d) points 
to automatic identification system requirements without reference to 
type of vessel. We made no changes from the proposed rule based on this 
comment.
    We received two comments on proposed Sec.  137.300, a section on 
documenting compliance with drydock and internal structural surveys 
requirements. One of these commenters referenced Sec.  136.130(d) in 
combination

[[Page 40028]]

with Sec.  137.300 when requesting clarification about the scope and 
frequency of such surveys. Both Sec.  136.130(d) and redesignated Sec.  
137.300(a) make it clear that the frequency does not change based on 
which option is chosen to obtain a COI. Further, we amended Sec.  
137.300(a) to clearly indicate that the drydock and internal structural 
intervals start after the issuance of the initial COI. Paragraphs 
(a)(1) and (2) of Sec.  137.300 clearly state the intervals for drydock 
and internal structural surveys. Finally, we established separate 
sections for vessels using the TSMS option (Sec.  137.305) and those 
using the Coast Guard inspection option (Sec.  137.302) to document 
compliance with drydock and internal structural survey requirements.
    Regarding the scope of drydock and internal structural surveys, 
whether a vessel provides objective evidence using the external survey 
option under Sec.  137.310 or the internal survey option under Sec.  
137.315 requirements (see these options referenced in redesignated 
Sec.  137.305(a) and (b)), the scope of the survey is clearly laid out 
in Sec.  137.330. Also, Sec.  137.325 contains a comprehensive 
inventory of items to be reviewed during the examination. The Coast 
Guard believes that the numerous items identified in Sec.  137.325, in 
addition to the supporting Sec.  137.330, provide sufficient 
information to address the commenter's concerns. As noted above, 
redesignated Sec.  137.300 makes clear that regardless of the option 
chosen to obtain a Certificate of Inspection, each towing vessel must 
undergo a drydock and internal structural examination at the prescribed 
intervals after the issuance of the initial COI. Accordingly, we have 
amended the Sec.  137.325 heading so that it no longer references just 
surveys for the TSMS option. Throughout amended subpart C of part 137 
we have changed the term ``survey'' to ``examination'' when referring 
to the drydock and internal structural examinations.
    A person commenting on proposed Sec.  137.300(c), which called for 
objective evidence of compliance with certain load line requirements in 
subchapter E, noted that load lines are not applicable to inland towing 
vessels. We agree that load lines are not applicable for situations 
where the inland towing vessel never operates on the Great Lakes or 
outside the Boundary Lines. But under Sec.  136.250, the load line 
requirement in subchapter E would apply to certain towing vessels 79 
feet or more in length that normally operate on inland waters but that 
sometimes operate on the Great Lakes or outside the Boundary Lines. In 
this final rule, we moved requirements for documenting compliance with 
load line and other requirements in this subpart to Sec.  137.305 for 
vessels choosing the TSMS option and to Sec.  137.302 for vessels 
choosing the Coast Guard inspection option. We recognize that 46 CFR 
42.03-5(b)(1)(v) in subchapter E excepts vessels that operate 
exclusively on inland waters and that do not engage in coastwise or 
Great Lakes voyages from load line requirements. However, Sec.  
137.305(c) and amended Sec.  137.320 make clear that the load line 
provision is only relevant for towing vessels subject to subchapter E 
load line requirements. Similarly, the provisions in new Sec.  137.322 
for vessels currently classed by a recognized classification society 
whose applicable rules have been accepted by the Coast Guard, are only 
relevant to vessels so classed.
    Redesignated Sec.  137.305 clarifies that objective evidence is 
needed to demonstrate that a vessel utilizing the TSMS option complies 
with the drydock and internal structural examination requirements of 
this subpart. Paragraph (c) points to Sec. Sec.  137.320 and 137.322. 
We amended Sec.  137.320 to make clear that an examination performed to 
maintain a valid load line certificate issued in accordance with 
subchapter E would count as an examination required under Sec.  
137.300. Also, new Sec.  137.322 allows for the same consideration in 
the case of a drydock and internal structural examination performed to 
maintain class by a recognized classification society whose applicable 
rules the Coast Guard has accepted. In the case of those vessels 
required to conduct two drydock and internal structural examinations in 
accordance with Sec.  137.300(a)(1), the allowance under either Sec.  
137.320 or Sec.  137.322 only counts for one of the required 
examinations.
    We received several diverse comments on proposed Sec.  137.305, 
which specifies intervals for drydock and internal structural surveys. 
One commenter observed that towing vessels operate in an environment 
that requires them to be in contact with barges and vessels, and that 
this contact puts unusual stresses to the hull. Based on this 
observation the commenter suggested that the survey intervals called 
for in proposed Sec.  137.305(a)(2), redesignated Sec.  137.300(a)(2), 
for vessels not exposed to salt water often should be the same as those 
with more saltwater exposure--at least twice every 5 years and not more 
than 36 months between drydockings--instead of just once every 5 years.
    The Coast Guard disagrees. The drydock and internal structural 
examination requirements in this final rule are consistent with the 
requirements for other vessels subject to inspection, and we see no 
reason to believe this frequency of drydocking would need to be 
increased for towing vessels. The Coast Guard will monitor the 
inspected fleet to see if increased frequency is called for in the 
future. As discussed earlier, proposed Sec.  137.305 has been 
redesignated as Sec.  137.300 in this final rule.
    Some commenters thought the provision of proposed Sec.  137.305 
should be amended to ensure vessels operating on the Great Lakes may 
receive a 1-year extension on the required interval for drydocking and 
interval structural examinations as provided under load line provisions 
in 46 CFR subpart 42.09 and current Coast Guard policy.
    The Coast Guard disagrees that modification to our applicable text, 
now found in Sec.  137.300, is needed. The extension of a Great Lakes 
Load Line certificate by the Ninth District Commander is addressed in 
46 CFR 42.07-45(d)(2). Existing Coast Guard policy, found in the Marine 
Safety Manual, Volume II, provides additional guidance to the Coast 
Guard and industry regarding extensions of drydock and internal 
structural examinations for Great Lakes vessels. The Ninth District 
Commander is also the approving authority for drydock extensions for 
these vessels, including towing vessels operating on the Great Lakes. 
While the same entity can issue both of these extensions, the load line 
certificate and the vessel's Certificate of Inspection must both be 
annotated with the new due date for the vessel's drydock and internal 
structural examination. We made no changes from the proposed rule based 
on this comment.
    Some commenters noted that a definition for ``saltwater'' is needed 
if the times of operation in ``saltwater'' is a factor in determining 
intervals for inspections.
    The Coast Guard did not add a definition for the term ``saltwater'' 
in the rule. The Marine Safety Manual, Volume II, places the 
responsibility of determining salt water and fresh water dry-docking 
and internal structural inspection intervals on the OCMI. If fresh 
water intervals are determined appropriate for a specific vessel, the 
OCMI will annotate the fresh water service intervals on the vessel's 
COI and evaluate that determination periodically. OCMIs maintain lists 
of boundary lines where fresh water ends, and salt water begins, within 
their particular zones.

[[Page 40029]]

    A commenter expressed concern about the cost of the requirements. 
He wrote that proposed Sec.  137.305 would impose enormous cost on 
small businesses, and that his company's vessels that operate in the 
Southeast in a saltwater environment would have to be drydocked twice 
every 5 years at an estimated cost of about $40,000 for each drydocking 
evolution for one vessel, or $80,000 per vessel every 5 years. Another 
commenter suggested that Sec.  137.305, requiring drydocking of 
saltwater vessels twice every 5 years, would cost his company at least 
$100,000 to $150,000 per vessel.
    The drydock and internal structural examination requirements in 
this final rule are consistent with the requirements for other vessels 
subject to inspection and necessary to meet the statutory requirements 
for vessel inspections. We have made no changes from the proposed rule 
based on this comment.
    With regard to the cost of drydocking, after publication of the 
NPRM, the Coast Guard sponsored a study of standard marine engineering 
services for use in regulatory analyses, titled ``Study of Marine 
Engineering and Naval Architecture Costs for Use in Regulatory 
Analyses'' by ABS Consulting, available on the docket. According to the 
Engineering Cost Study, cost of drydocking can vary based on a variety 
of factors, including vessel size, vessel weight, equipment, type of 
work, operating environment and location of the drydock.\2\ The 
Engineering Cost Study summarizes the minimum, average and maximum 
costs of drydocking for various vessel types in Table 6-9, page 32. The 
Engineering Cost Study does not report a separate cost category for 
towing vessels. The Coast Guard uses the costs for smaller Freight 
Ships and Industry Vessels as a proxy for towing vessels based on 
similar size and operating characteristics. Based on the Engineering 
Cost Study, the minimum cost for a drydocking of a towing or similar 
vessel is $2,000, the maximum is $20,000 and the average is $9,250. We 
consider the $9,250 as the best available estimate for the average cost 
of drydocking. We acknowledge that the $40,000 estimate provided by the 
commenter is feasible given the variability of factors, such as size 
and location. To account for the variability, we assume that the 
$40,000 cost is at the 90th percentile of the distribution of costs, 
that is, 10 percent of vessels will incur this cost for drydocking. As 
a result, we modify the average cost to reflect the upper 10th 
percentile cost of $40,000, for a weighted average cost of $13,250. As 
per the regulatory requirements, vessels that are not currently covered 
by a safety management system are assumed to incur this cost once every 
5 years for freshwater vessels and twice every 5 years for saltwater 
vessels.\3\ For a more detailed discussion of the costs, see section 
3.3 of the Regulatory Analysis which is available in the docket.

---------------------------------------------------------------------------

    We received a few comments on proposed Sec.  137.315. Some 
commenters were unclear whether the requirement of notification prior 
to commencing work at the drydock refers to any drydock work or only 
those drydock visits that are required by the TSMS.
    In response, we amended Sec.  137.315(d) to clarify when to notify 
the Coast Guard under paragraph (d) and TPOs under paragraph (b) of 
activities related to credit drydocking or internal structural 
examinations.
    A few commenters asked that Sec.  137.315 be modified to clarify 
that the items described in Sec.  137.330 need not be examined as one 
event, but may be examined on a schedule over time.
    Section 137.315(c) states that ``The interval between examinations 
of each item may not exceed the applicable interval described in Sec.  
137.300.'' The Coast Guard believes the words ``examinations of each 
item'' provides clear guidance that an owner or managing operator of a 
towing vessel may select to survey different items described in Sec.  
137.330 during multiple events, and the remainder of Sec.  137.315(c) 
makes clear that the interval for surveys of a given item must not 
exceed the applicable interval described in Sec.  137.300.
    Several commenters argued that proposed paragraph (a) of Sec.  
137.325, requiring a surveyor to determine that the hull and related 
structure and components are free of defects or deterioration, would be 
too difficult to meet. One commenter suggested language we used in 
proposed Sec.  137.335(c)(3) regarding underwater inspections--``free 
from appreciable defects and deterioration''--stating that it does not 
make sense to require a higher standard for a vessel on drydock than 
one being inspected in the water.
    The Coast Guard agrees with the commenters with respect to the term 
``free of defects [and] deterioration.'' We have amended Sec.  
137.325(a), to remove the term ``free of'' and have further rearranged 
the paragraph so that the standard for evaluating the listed items 
detected in the hull and related structure and components is whether 
they ``adversely affect the vessel's seaworthiness or fitness or 
suitability for its route or service'' instead of ``reducing 
effectiveness.'' Also, in Sec.  137.325(a), we changed ``determine 
that'' to ``determine whether'' to better reflect the purpose of the 
survey: To determine if standards are met. In response to the second 
comment, the Coast Guard amended Sec.  137.335 by removing the word 
``appreciable'' to provide a more consistent standard with that of 
Sec.  137.325(a), and by reorganizing the section to better clarify its 
intent.
    Two commenters expressed general opposition to the proposed 
requirements and scope for regular mandatory drydock examinations. One 
commenter stated that harbor service boats are already being retired on 
a regular basis when their structural usefulness is at an end, and 
therefore mandatory structural inspections are not warranted. The 
commenter also noted the cost of additional boats to fill the service 
void when these boats are in transit to a certified inspection drydock 
and when undergoing a drydock inspection. Another commenter was 
specifically concerned that proposed Sec.  137.330 was vague regarding 
pulling the tail shafts for inspection.
    Because of the nature of towing, the hulls of towing vessels are 
exposed to the unique hazards that result in degradation and damage to 
the towing vessel in the normal course of operation. For this reason, 
regular drydocking of a towing vessel to inspect its underwater areas 
is a necessary component of assessing and verifying fitness for 
service. We note, however, that as proposed in the NPRM, Sec.  137.335 
in this final rule identifies situations where it may be acceptable to 
conduct an underwater survey in lieu of a drydocking.
    The Coast Guard notes that scope of drydock examination required by 
Sec.  137.330 is the same for both seagoing and inland service. The 
Coast Guard believes Sec.  137.330 clearly lays out the scope of the 
required drydock examination for all towing vessels subject to 
subchapter M. Our proposed definition of ``drydock'' in Sec.  136.110 
actually defines a drydock examination (as opposed to the physical 
dock) and matches the definitions of that term in subchapters K and T, 
so we amended the term being defined to ``drydock examination.''
    Regarding examination of tail shafts, the Coast Guard proposed

[[Page 40030]]

Sec.  137.330(a)(2) to permit the surveyor or inspector to conduct the 
required examinations using different means than pulling the tail 
shaft, so long as the method used allows the surveyor or inspector to 
properly evaluate the tail shaft for bends, cracks, and damage. These 
methods may include technologies such as non-destructive testing and x-
ray. The Coast Guard has not made any changes from the proposed rule 
based on these drydocking and tail shaft comments.
    Regarding the cost of additional boats to fill the service void 
when these boats are in transit to a certified inspection drydock and 
when undergoing a drydock inspection, the Coast Guard has added an 
estimate of lost revenues (rather than the cost of replacement) to 
account for the potential impacts of vessels being out of service due 
to drydock inspections. Further information is available in Section 2.5 
of the Regulatory Analysis.
    We received a few comments on Sec.  137.335, which sets out 
provisions for an underwater survey in lieu of drydocking. One 
commenter expressed support for the provision. One commenter suggested 
that for purposes of determining whether an underwater survey is 
appropriate, the age of the hull should be used rather than the age of 
the towing vessel.
    The Coast Guard does not agree that we should use the age of a 
given vessel's hull as opposed to the vessel's age when considering 
eligibility for enrollment in an underwater inspection in lieu of 
drydocking (UWILD) program. For an existing vessel with no prior credit 
drydock overseen by the Coast Guard, we have no criteria to make an 
``age of hull'' determination. Once inspected, a completely new hull 
will likely be considered as a major modification and reset the 
vessel's age for purposes of UWILD enrollment.
    While we did not make a change from the proposed Sec.  137.335 
based on these comments, we did amend Sec.  137.335 to clarify the 
process for the UWILD program by stating that it is the Coast Guard 
that determines if the stated criteria for eligibility has been met.
    One commenter opposed several vessel compliance provisions in part 
137. He argued that requirements for training and recordkeeping will be 
an excessive burden on small companies, a distraction to pilots, and 
cause undue hardship for vessel owners; that vessel managing operators 
should not have to get permission to put visitors, company 
representatives, or additional personnel on the vessel; and that 
restrictions in routes permitted on the COI would be a deterrent to his 
ability to make a living and provide employment for his personnel. 
Other commenters noted that the paperwork requirements would distract 
pilots while they are steering their towing vessels.
    The Coast Guard views the TSMS, and its requirements for records to 
document compliance with regard to training, as the foundational 
document itemizing the standards, processes and management systems 
necessary to improve maritime safety aboard towing vessels. Towing 
companies that lack the resources to develop and implement a TSMS may 
choose the Coast Guard inspection option and will not have to maintain 
the TSMS-required records and documents. We note, however, that 
personnel record requirements in Sec.  140.400(a) and (b) apply to all 
vessels subject to subchapter M; in response to this comment we have 
made clarifying amendments to those paragraphs. With respect to 
associated paperwork, many of the entries are short in duration and the 
Coast Guard does not mandate when the paperwork is filled out.
    Regarding crews and visitors, the Coast Guard will issue 
certificates of inspection that establish the level of manning and 
persons in addition to the crew that will be allowed to be on board the 
vessels. Companies should work with OCMIs prior to issuance of the COI 
to request any additional personnel above what the required manning 
level would normally be. The Coast Guard does not agree with the 
commenter's assertion that the OCMI does not need to be contacted to 
carry additional personnel (visitors, company reps, etc.) beyond what 
is stated on the COI. We note that Sec.  136.245 provides for the 
issuance of an excursion permit by the OCMI as needed.
    The application for inspection allows owners and managing operators 
to request the routes necessary to accomplish their business. OCMIs 
will evaluate that request to determine if the vessel meets the 
standard for the routes being requested. Those standards are found in 
parts 140 through 144. We made no changes from the proposed rule based 
on these comments.
    One maritime company expressed concerns regarding added operating 
costs incurred that will stem from drydock inspection fees paid to 
surveyors or the Coast Guard, and from audit exams and what the 
maritime company considers unnecessary repairs brought upon the 
industry by non-risk-based regulations.
    The requirement to have a surveyor from a TPO conduct a drydock and 
internal examination is predicated on the option chosen to obtain a 
COI. The Coast Guard encourages the owner or managing operator of a 
vessel using the TSMS option to discuss such costs with the company's 
TPO, as appropriate.
    One commenter predicted the cost of surveys would likely increase 
for both small and large companies, citing the demand for Coast Guard-
approved surveyors from TPOs and the increased scope of surveys. He 
noted many common repairs that can now be performed without requiring 
independent surveys will require independent surveys under this rule.
    The Coast Guard does not accept the premise that this rule imposes 
a requirement that independent surveyors must be involved before common 
repairs are performed. Regarding repairs, under Sec.  137.305, the OCMI 
may require additional examination of a vessel whenever he or she 
discovers or suspects damage or deterioration to hull plating or 
structural members that may affect the seaworthiness of a vessel. We 
believe the OCMI should be able to require additional examinations when 
he or she discovers such conditions, and we note that such examinations 
are typically reserved for those dry-docking and topside surveys 
required by part 137. We note also that under Sec. Sec.  137.135(a)(12) 
or 137.210(a)(3) there is a requirement to identify items that need to 
be repaired or replaced before the vessel continues in service, but 
this would not require a TPO survey before common repairs could be 
made.
    Regarding the need for surveyors from TPOs, under the Coast Guard 
option, annual inspections are performed by Coast Guard personnel and 
do not require participation of a surveyor from a TPO. Similarly, if a 
company has a TSMS and chooses an internal survey program, the surveys 
can be conducted by a qualified member of the company and would not 
require a TPO. If a company with a TSMS uses the external survey 
program, they would incur additional costs of using a surveyor from a 
TPO.

H. Towing Safety Management System (TSMS) (Part 138)

    We received many comments on our proposed part 138 TSMS 
requirements. We received several comments with regard to the schedule 
for the TSMS option. An individual suggested that the implementation of 
a TSMS should occur immediately with the allowance of a 6-month interim 
certificate. This commenter stated using an interim basis approach, as 
is done with the ISM Code, will prevent reinventing the wheel and align 
the system approach to existing requirements.
    We have made a number of changes, as explained in this section to 
provide

[[Page 40031]]

for a smooth implementation of the TSMS option while keeping in mind 
the burden to owners and managing operators. In the NPRM, we proposed 
that owners and managing operators who select the TSMS option would 
have 2 years from the effective date of a final rule to create their 
TSMS, have a TPO approve it and then issue a TSMS certificate. The 
owners and managing operators would then have 4 years from the date of 
that TSMS certificate to bring all vessels under their ownership or 
management into the TSMS and obtain COIs for them.
    In this final rule, we changed Sec.  138.115 so that owners or 
managing operators of towing vessels need only to obtain a TSMS 
certificate issued under Sec.  138.305 at least six months before being 
able to have any of their vessels obtain a Certificate of Inspection 
under the TSMS option. We made this change to better account for the 
time needed for third parties to obtain approval from the Coast Guard 
and for owners and managing operators to obtain approval of their TSMS 
from these third parties before being required to have their vessels 
obtain a COI. We also believe that six months of implementing a TSMS is 
sufficient for obtaining a COI, and as required, the vessel would need 
to have on board a copy of the owner or managing operator's TSMS 
certificate. We amended Sec.  138.115 to more closely align the 
deadline with the deadlines for vessels to obtain a COI, but this 
change does not prevent a company from implementing a TSMS sooner and 
we encourage owners and managing operators to obtain the TSMS 
certificate and implement their TSMS as soon as possible. In making 
this change, we do not believe there is a need for a 6-month temporary 
certificate.
    Two commenters expressed their view that utilizing internal and 
follow-up audits would mean that there would be no need for a TSMS.
    The Coast Guard does not agree that merely conducting audits and 
surveys would negate the need for TSMS. The TSMS is the foundational 
document itemizing the standards, processes, and management systems 
that the auditor would review, assess, and validate. Without a TSMS, or 
some other form of Safety Management System, there would be no 
documentation to identify the processes and management system(s) put in 
place for a vessel choosing the TSMS option. We made no changes from 
the proposed rule based on these comments.
    We received comments from maritime companies and a professional 
association suggesting that proposed Sec. Sec.  138.205, 138.210, 
138.215, and 138.220 pertaining to the purpose, functional 
requirements, and elements of the TSMS be revised to be more simplistic 
and to more clearly state the primary goals of a TSMS.
    We believe the purpose, objectives, functional requirements, and 
elements presented in these four sections in part 138, subpart B, 
succinctly establish reasons for, and the requirements and goals of, a 
safety management system. The Coast Guard incorporates these core 
elements to provide consistency with the ISM Code and to identify the 
elements that must be addressed when developing a TSMS. In response to 
a previous comment, we did revise our definition of ``safety management 
system,'' which identifies the nature of an SMS and who it enables to 
effectively implement the safety and environmental protection 
requirements of subchapter M. Additional guidance will be developed to 
help the industry and public understand the goals of a TSMS and how to 
develop and implement one.
    Some commenters requested clarification regarding the proposed 
functional requirements in Sec.  138.215(f) and TSMS elements in Sec.  
138.220(e) related to the phrase ``procedures to manage contracted 
(vendor safety) services.'' The commenters suggested that the 
management of all hired (contracted) towing vessels to ensure they 
comply with subchapter M would be a burden, and they suggested that 
proof of the hired company's TSMS and vessel's COI should be sufficient 
evidence to meet the intent of the rule. One of the commenters stated 
that it is unclear what contracted services are covered by Sec.  
138.220(e).
    The Coast Guard agrees. When contracting their vessels to others 
for towing services, the owner and operator remain responsible for for 
verifying that their vessels are in compliance with the regulations. We 
have removed the requirements proposed in Sec. Sec.  138.215(f) and 
138.220(e).
    We received several comments from maritime companies that conveyed 
concern regarding the proposed requirement in Sec.  138.220(b)(1) for 
employers to, ``ensure personnel are . . . mentally capable to perform 
required tasks.'' The commenter's stated that although employers 
conduct drug testing, safety training, and physical examinations, the 
employers cannot be responsible for determining their mental health 
status.
    The Coast Guard agrees that it may be unreasonable for the company 
to determine the mental health of a crewmember. It is reasonable, 
however, for companies to identify if potential crew members are able 
to perform required tasks. For this reason, we have edited the quoted 
language in Sec.  138.220(b)(1) to require the TSMS to contain 
employment procedures which ensure ``that personnel are able to perform 
required tasks.''
    We received a comment requesting more details regarding crew member 
(master, mate, able seaman, pilot, etc.) responsibilities in the 
operation, managing, and implementation of the TSMS and the vessel.
    The Coast Guard does not agree that the regulations should contain 
more details on crew responsibilities and believes that this should be 
left to the discretion of the owner or managing operator to set in the 
TSMS. Under Sec.  138.220(b), policies must be in place in the TSMS 
that cover the owner or managing operator's approach to managing its 
personnel, including the duties and responsibilities of the 
crewmembers.
    We received comments from individuals and a maritime company 
recommending that the rule ensures that major non-conformities, non-
conformities, accidents, and hazardous situations are reported to the 
owners, company, or managing operators; are investigated and analyzed 
with the objective of improving safety and pollution prevention; and 
that auditors notify the Coast Guard and the company immediately of any 
serious, unsafe situation that threatens the vessel, its personnel, or 
the environment. One commenter noted that TSMS requires a designated 
person to whom crewmembers can report safety violations, but that 
towing vessels opting for the Coast Guard inspection option would not 
have this reporting system that would likely prevent accidents. Another 
commenter recommended supplementing the text in Sec.  138.220(a)(1)(ii) 
to ensure that the designated person monitors the safety and pollution 
prevention aspects of the operation of each vessel and ensures that 
adequate resources and shore-based support are applied.
    With respect to reporting accidents and non-conformities, we note 
that Sec.  138.215(c) requires TSMSs to include procedures for 
reporting both. Section 138.220(a)(2)(ii) requires that the TSMS 
include procedures to identify and correct non-conformities. The TSMS 
must include how an initial report should be made and the actions taken 
to follow up and ensure appropriate resolution.
    For vessels choosing the Coast Guard option the corresponding 
``designated person'' is the vessel's Master. In part 140 on 
operations, Sec.  140.210(d)(6)

[[Page 40032]]

requires the crew to report unsafe conditions to the Master and take 
the most effective action to prevent accidents.
    The Coast Guard disagrees with adding specific regulatory text to 
Sec.  138.220(a)(1)(ii) regarding the designated person. Section 
138.220(c) requires the TSMS to have an element that addresses 
verification of vessel compliance that covers the safety and pollution 
prevention aspects that the commenter alluded to. Ultimately the 
designated person is responsible for ensuring the TSMS is implemented 
and continuously functions to address concerns identified by the 
commenter.
    On the issue of protecting the responsibilities and authority of 
masters, we received comments suggesting that the TSMS specifically 
states that the master has overriding authority to make decisions 
regarding the company's safety and pollution prevention.
    The Coast Guard agrees that the master of a towing vessel has 
overriding responsibility and authority to ensure the safety of his or 
her vessel. As stated in Sec.  138.220(a)(1)(iii), the Master's 
authority, as defined by the owner or managing operator in the TSMS, 
must provide for his or her ability to make final determinations on 
safe operations of the towing vessel including the ability to cease 
operations if an unsafe condition exists. This reflects provisions in 
operational regulation Sec.  140.210 which specify that safety of the 
towing vessel is the responsibility of the master and that if the 
master believes it is unsafe for the vessel to proceed, he or she must 
not proceed until it is safe to do so.
    We received many comments from maritime companies that recommend 
that the Coast Guard accept the AWO RCP as an approved TSMS. Commenters 
wrote about the wide use of the RCP and attested to the success that 
their company has experienced implementing that program. Several 
commenters also suggested that because AWO RCP has been developed from 
the ISM code, which we already noted as being accepted in the NPRM, the 
AWO RCP should qualify as an approved TSMS.
    The provisions of Sec.  138.225 state that an SMS that is fully 
compliant with the ISM Code requirements of 33 CFR part 96 will be 
deemed in compliance with TSMS requirements in part 138. It also states 
that the Coast Guard may consider other existing safety management 
systems as meeting part 138 requirements. The Coast Guard will examine 
AWO's RCP to determine whether or not it meets the requirements of 46 
CFR part 138 in order to determine if it qualifies under the provisions 
of this section. We have not made a change from the proposed rule based 
on these comments.
    We received comments from several maritime companies that 
recommended the sequence of events for the issuance of a COI for towing 
vessels be provided.
    The Coast Guard notes the following short sequence of events 
associated with the various ways to obtain a COI:
    Step 1: As specified in Sec.  136.210, Obtaining or renewing a 
Certificate of Inspection (COI), the owner or operator must submit a 
completed CG-3752, Application for Inspection of U.S. Vessel, to the 
cognizant OCMI. As noted in Sec.  136.130(d), the applicant must 
specify the option--TSMS or Coast Guard Inspections--when submitting 
the Application for Inspection for a vessel.
    Step 2: Under Sec.  136.212, the Coast Guard will inspect the 
vessel at least once every 5 years for certification.
    Step 3: As specified in Sec.  136.212(c) of this final rule, the 
OCMI will issue a vessel a new Certificate of Inspection after the 
vessel successfully completes the inspection for certification.
    With respect to this process, and as noted previously, we amended 
Sec.  138.115 so that owners or managing operators of towing vessels 
selecting the TSMS option need to obtain a TSMS certificate at least 
six months before being able to have any of their vessels certificated. 
We believe this is more consistent with the required schedule of when 
vessels must obtain a COI as shown in Sec.  136.202 when considering 
the time needed for third parties to obtain Coast Guard approval and 
for owners and managing operators to obtain approval of their TSMS from 
the third parties.
    Five maritime companies suggested that additional language be 
provided in Sec.  138.305 to clarify how a third-party is to respond 
when a non-conformity is discovered and what the appeals process will 
be for a company whose certificate is rescinded.
    The Coast Guard agrees and has added language to Sec.  138.505(a) 
to specify that the results of any external audit of the owner or 
managing operator's compliance with Sec.  138.315 of this part must be 
submitted to the Towing Vessel National Center of Expertise within 30 
days of audit completion by the TPO conducting the external audit. 
Further, we amended our definition of ``non-conformity'' in Sec.  
136.110 to clarify that it is referring the non-fulfillment of a safety 
management system specified requirement. On reviewing proposed Sec.  
138.215(j) procedures for evaluating recommendations, which has been 
redesignated as Sec.  138.215(i), to be more consistent with other 
quality control and safety management systems, we amended its reference 
to the source of the recommendations to include more company personnel, 
and made a similar edit in Sec.  138.220(a)(2)(ii) regarding reporting 
non-conformities.
    Regarding the appeal process, in proposed Sec.  136.180 we stated 
that any person directly affected by a decision or action taken under 
this subchapter by or on behalf of the Coast Guard, may appeal in 
accordance with subpart 1.03 in subchapter A of this chapter. In 
response to comments, the Coast Guard has added Sec.  1.03-55 to 
identify the Coast Guard official or entity appeals should be directed 
to, including the appeal of matters relating to action of a third 
party, such as when a TPO rescinds a TSMS certificate.
    A professional association noted that, as written, proposed Sec.  
138.305 would require that all towing vessels in a fleet that are in 
compliance with the TSMS be included on the company's TSMS certificate. 
The commenter stated that this provision would render an entire fleet 
invalid if a TSMS is revoked under proposed Sec.  138.305(d), and 
therefore, a paragraph needs to be added to this section detailing the 
appeals process for the rescinding of a TSMS, which mirrors the current 
Coast Guard appeals process for rescinded COI's. One commenter 
suggested that the proposed requirement in paragraph (c) to list 
vessels on a TSMS certificate is cumbersome and unnecessary.
    The Coast Guard understands the commenter's concern and has amended 
Sec.  138.305, so that owners or managing operators need only maintain, 
and produce on request, a list of vessels currently covered by each 
TSMS certificate. This is a less burdensome means of requiring this 
information.
    Exceptional circumstances such as failure to complete a required 
audit, major non-conformities discovered during an audit or survey, and 
failure to fully implement their TSMS could render the TSMS certificate 
invalid for a company's entire fleet. Based on the Coast Guard's 
experience with other safety management systems, including ISM, these 
circumstances have been rarely observed. It is more likely that an 
infraction of the regulations would result in a less drastic response--
for example, in the form of non-conformities being reported for the one 
or few vessels involved, or those vessels being removed from the list 
of vessels found to be in compliance with the TSMS.

[[Page 40033]]

    If the situation warrants, the TPO that issued the TSMS certificate 
is able to rescind the certificate, which could impact the entire 
fleet, or remove one or more vessels from the list of vessels on the 
TSMS for non-compliance with the requirements of part 138. Such an 
action that would render the certificate no longer valid would indeed 
impact the entire fleet of vessels listed in that TSMS certificate. 
Also, we note that the Coast Guard may suspend or revoke the TSMS 
certificate at any time for non-compliance with the requirements of 
part 138. As discussed above, we have added 46 CFR 1.03-55 to clearly 
identify the Coast Guard official or entity appeals should be directed 
to for those seeking to appeal a decision by a TPO under Sec.  
138.305(e) to rescind, or a Coast Guard official under Sec.  138.305(d) 
to suspend or revoke, a TSMS certificate.
    In commenting on Sec.  138.305(f) requirements, an individual 
suggested it is unnecessary for a copy of the TSMS certificate to 
remain onboard the vessel because the certificate will be on file at 
the Captain of the Port (COTP) and at the company's office.
    The Coast Guard does not agree. Some towing vessels will frequent a 
number of COTP zones. The TSMS certificate provides evidence that a 
vessel covered by the TSMS was found to meet 46 CFR part 138 
requirements, and a copy on board the vessel will be readily available 
to Coast Guard officials wherever the vessel is operating.
    A transportation company suggested that two certificates should be 
issued instead of one: A Towing Company Safety Management System 
Certificate to the office and a Towing Vessel Safety Management System 
Certificate to each towing vessel. One commenter recommended and 
provided text for a new section that would provide information on how 
to obtain such certificates.
    The Coast Guard does not agree. A TSMS is intended to be the 
central document that directly links the towing vessel and the shore-
based management operation. The TSMS is not only for the vessel or only 
for management. Rather, it is the documentation of processes, 
responsibilities and required action defining the mutually supporting 
actions between the vessel mariners and management. A TSMS certificate 
should be the only document issued attesting to the acceptability of 
the system. This should reduce the paperwork burden on industry and 
TPOs.
    We received comments suggesting the removal of the proposed 
requirement for an internal auditor to be a person outside of the 
organization. Commenters felt that this requirement could make it 
difficult for small companies to comply. Others suggested that a person 
who is involved in the development of the TSMS would be useful in 
identifying areas where the system is not meeting standards. Several 
comments from maritime companies felt that the requirements for 
internal auditors should mirror ISM Code 12.4, which states that 
``Personnel carrying out audits should be independent of the areas 
being audited, unless this is impracticable due to the size and the 
nature of the Company.''
    The Coast Guard believes that some of these comments are based on a 
misreading of Sec.  138.310. The section does not require an internal 
auditor to be a person outside of the organization. However, to come 
closer to the desired objectivity of a third-party organization, the 
internal auditor may not be a person involved in the implementation of 
the TSMS. In response to these comments on Sec.  138.310, the Coast 
Guard has amended Sec.  138.310(d)(4) to include qualifying language 
from ISM code 12.4: The auditor must be independent of the procedures 
being audited, unless this is impracticable due to the size and the 
nature of the organization. Thus, very small organizations may 
potentially use someone from within their organization to perform the 
audit.
    Some commenters also recommended that the proposed requirement, in 
Sec.  138.310(d)(2), for internal auditors to have completed ISO 9001-
2000 courses be deleted.
    The Coast Guard does not agree. We believe that a robust auditing 
system that includes both internal and external auditing processes 
serves to enhance the effectiveness of a safety management system and 
provides a venue for identification of deficiencies and a process for 
corrective action. Requiring internal auditors to have completed an ISO 
9001-2000 internal auditor/assessor training course, or a Coast Guard-
recognized equivalent course, is intended to ensure that the internal 
auditor is familiar with basic auditing standards and procedures. 
However, we want to accept those who have been trained under newer ISO 
9001-2008, so we amended Sec. Sec.  138.310(d) and 139.130(b)(3) to 
include that standard. In this final rule, both the ISO 9001-2000-based 
training we referenced in the NPRM and the ISO 9001-2008-based training 
meet our qualification requirement. The intended result of this 
training is to ensure that the internal audit meets minimum standards.
    One commenter requested more information regarding the accepted 
course work for internal auditors. An individual offered suggestions 
for the minimum education for internal auditors.
    The Coast Guard disagrees. The Coast Guard has incorporated ISO 
9001 standards for internal auditor competencies in Sec.  138.310 to 
reflect the best practices found in industry. The Coast Guard does not 
agree that standards either less than or in excess of these minimum 
competencies enhance the credibility of the internal auditing process. 
We made no changes from the proposed rule based on these comments.
    We received comments that requested clarification of our 
requirements for external audits in Sec.  138.315. One commenter 
opposed the provision in Sec.  138.315(b)(2) that vessels must be 
selected randomly for an external audit during the 5-year period of 
validity of the TSMS certificate, which the commenter viewed as 
subjecting a vessel to multiple external audits. He suggested that 
satisfying Sec.  136.203 requirements for vessels with TSMS 
certificates should be sufficient. Another was confused by Sec.  
138.315(b)(2)'s requirement for an external audit prior to the issuance 
of the TSMS certificate because he felt it was the initial audit that 
leads to the TSMS certificate. One commenter questioned why we called 
for random audits.
    In response to these comments we have changed Sec.  138.315(b) to 
clarify the requirements for external vessel audits. We removed the 
requirement in proposed paragraph (b)(1) regarding the need for an 
external audit on all vessels prior to an owner or managing operator 
receiving the initial TSMS certificate. Upon reconsidering this 
provision we determined it is not necessary and instead we considered 
the need for vessel to undergo an external audit in relation to the 
initial COI for the vessel. And in doing so we considered the two 
different categories of vessels for which an owner or managing operator 
would need to obtain an initial COI. First, there are the vessels that 
have been owned or operated for more than six months which generally 
will include all existing vessels that are now coming under this 
subchapter. Secondly, there are newly constructed vessels as well as 
existing vessels that an owner or managing operator may obtain, all of 
which will need a COI to operate but which have been owned or operated 
for less than 6 months. For the first category, Sec.  138.315(b)(1) 
requires the vessel to undergo an external audit prior to obtaining the 
initial COI. For the second category, Sec.  138.315(b)(2) requires that 
the vessel undergo an external audit no

[[Page 40034]]

later than 6 months after receiving the initial COI. We note, that as 
required by Sec.  138.505(b), the results of all external vessel audits 
are required to be provided to the cognizant OCMI. We believe that 6 
months of operation is sufficient for owners or managing operators to 
fully implement their TSMS on their towing vessels and is also 
consistent with other SMS provisions including the duration of interim 
ISM vessel certificates.
    Proposed Sec.  138.315(b)(2) has remained the same but is now Sec.  
138.315(b)(3). The other change we made was to add Sec.  138.315(b)(4) 
to clarify that not all information for an external audit necessarily 
needs to come from the vessel examination as some may be obtained from 
the owner or managing operator's office but that however, some of the 
information must be obtained by visiting the vessel.
    As noted, we made these changes to clarify when vessels need to 
undergo an external audit as well as the relationship between the 
external audit and a vessel's initial COI.
    As for the comment regarding confusion caused by Sec.  
138.315(b)(2), (now Sec.  138.315(b)(3)), we note that, as proposed, 
paragraph (b)(1)'s requirement for an external audit of the vessel 
before issuance of the initial TSMS certificate is separate from 
paragraph (b)(2)'s requirement that an external audit of each vessel 
must be conducted during the 5-year period of validity of the TSMS 
certificate. We didn't view these requirements as confusing or 
conflicting but as noted above, we have removed the requirement 
proposed in Sec.  138.315(b)(1). Nor do we consider Sec.  138.315's 
sequencing of external management audits and vessel audits as 
confusing. As noted above, we removed proposed Sec.  138.315(b)(1) and 
replaced it with provisions in (b)(1) and (b)(2) to specify when an 
external vessel audit is required relative to a vessel receiving the 
initial COI. Note that Sec.  138.315(a)(2) and new Sec.  138.315(b)(3) 
continue to specify the external management and vessel audits required 
during the validity period of the TSMS certificate. It is important 
that all vessels undergo one external audit every five years along with 
external management audits to verify that an owner or managing 
operator's TSMS have been fully implemented and the TSMS certificate 
can be renewed. In proposed Sec.  137.210(c), we did state that before 
it could be placed in an audited program, a towing vessel must 
successfully complete an initial audit by a third-party organization, 
and then be audited as required by part 138. In this final rule we 
removed any reference to an initial audit in part 137.
    One commenter recommended replacing the random selection with a 
requirement for at least one intermediate verification between the 
second and third anniversary dates of the TSMS certificate. Another 
commenter stated that Sec.  138.315's sequencing of external management 
audits and vessel audits seems confusing.
    The commenter's concern about proposed Sec.  138.315(b)(2)'s, now 
Sec.  138.315(b)(3)'s, random-selection provision is unwarranted 
because that paragraph specifically calls for only one (``an'') 
external audit of vessels during the 5-year period. In addition, as 
noted previously, we added Sec.  138.315(b)(4) to allow for the use of 
objective evidence to verify compliance with some portions of the 
audit; however, some portions require visiting each vessel during the 
5-year period. We call for the vessels to be selected randomly to 
provide a risk-based approach and maximum flexibility for ensuring 
continual compliance with this subchapter. Therefore, we decline to 
amend Sec.  138.315 to remove the random-selection provision.
    We received comments from several companies noting that the 
proposed requirement in Sec.  138.315(c), that audit documents to be 
maintained for 5 years and submitted to Coast Guard upon request, 
appears to conflict with the proposed Sec.  138.505 requirement that 
the owner or managing operator submit each audit to the Coast Guard.
    The Coast Guard agrees that these two sections contain different 
record requirements, but we do not view them as conflicting 
requirements. Paragraph (c) of Sec.  138.315 calls for the maintenance 
of external audit results so that they are available when requested by 
the Coast Guard inspectors or an external auditor. Coast Guard 
inspectors may not have access to those audit reports submitted to the 
TVNCOE and external auditors may not otherwise have access to results 
from previous TPOs' management or vessel audits. The Coast Guard has 
amended Sec.  138.505 to clarify who the submission is required to go 
to and the submission timeframe for the external audit results.
    Three commenters suggested that a provision be added to Sec.  
138.315 that states the OCMI or COTP may be able to extend the external 
audit time period due to the unavailability of an TPO.
    The Coast Guard declines. Paragraphs (a) and (b) of Sec.  138.315 
establish a range of time for companies and TPOs to schedule external 
audits. A TPO that has been contracted to oversee the towing company's 
TSMS program is responsible for maintaining the audit cycles required 
by the regulations. The TPO has the ability to enter into contractual 
agreements to conduct required audits. However, in response to these 
comments, we added a paragraph (l) to Sec.  139.120 to clarify the 
responsibilities of the TPO in regards to conducting required external 
audits and surveys within the intervals established in this subchapter.
    Some commenters recommended that text be added to Sec.  138.410 to 
address the process an auditor must follow when he or she identifies a 
non-conformity. These commenters recommended adding a requirement that 
the TPO notify the owner or managing operator and the Coast Guard 
immediately of any recognized hazardous condition that poses an 
imminent hazard to personnel, the towing vessel, or the environment. 
For less serious non-conformities, these commenters recommended that 
the auditor only require the owner or managing operator to develop and 
implement a corrective action plan.
    The Coast Guard agrees with the commenters' suggested edits. First 
of all, we amended Sec.  138.505 to make clear where external audit 
result reports are to be submitted. Under Sec.  138.505, all detected 
non-conformities would be reported to the Coast Guard because they 
would be part of the results of any external audit. Section 138.505 
contains requirements on what is to be submitted to the Coast Guard by 
the external auditor and when it is to be submitted. In addition, we 
also amended Sec.  138.410 to require the auditor to notify the Coast 
Guard within 24 hours of discovering a major non-conformity which, as 
defined in Sec.  136.110, would cover hazardous conditions that pose 
imminent hazards. We also amended Sec.  138.410 in response to this 
comment to ensure the auditor reports major non-conformities to the 
owner or managing operator.
    We received several comments, particularly from maritime companies, 
requesting that we add language to proposed Sec.  138.500 to specify 
which Coast Guard office or official the owner or managing operator 
should notify prior to conducting a third-party audit and to clarify 
that the Coast Guard's attendance at such audits--attendance that Sec.  
138.500(b) allows the Coast Guard to require--would not or should not 
cause delays in the audit.
    The Coast Guard has amended Sec.  138.500(a) in response to these 
comments to include a notification to the cognizant OCMI at least 72 
hours prior to an external audit to mitigate potential delays in the 
conduct of the audit from Coast Guard scheduling, if

[[Page 40035]]

attendance is required. In a related amendment, we deleted Sec.  
139.170 in its entirety because those requirements are already stated 
in parts 137 and 138.
    A company suggested that Sec.  138.505 clarify that audit records 
only be provided to the Coast Guard upon request. Also, a maritime 
company requested to be able to submit documents required by Sec.  
138.505 electronically.
    The Coast Guard disagrees with the suggested change to Sec.  
138.505 to only provide records upon request. Final reports from the 
external management and vessel audits must be provided to the Coast 
Guard within 30 days of an audit. For the Coast Guard to properly 
oversee vessels using subchapter M's TSMS option, it is important that 
it receives final reports soon after they are completed. As noted 
above, we set the 30-day submission deadline in response to a previous 
comment. We note that in addition to this submission requirement, Sec.  
138.315(c) requires records of external audits to be maintained for 5 
years and made available on request. These reports are valuable 
historical records that must be available when needed by internal and 
external auditors as well as by the Coast Guard.
    As for submitting external audits records or results required by 
Sec.  138.505 electronically, we noted earlier that we amended Sec.  
140.915(b) to provide safeguards against false or late electronic 
entries in towing vessel and TSMS records. If the submitter uses 
equivalent safeguards for transmitting records, the Coast Guard will 
accept electronically transmitted external audits records that Sec.  
138.505 directs be submitted to the Towing Vessel National Center of 
Expertise (managing operator's compliance audits) and the cognizant 
OCMI (towing vessels external audits) so long as the means used allows 
the Coast Guard to reliably verify the person making the submission and 
the authenticity of the external audit records. For those seeking to 
submit external audits records or results to the Coast Guard 
electronically, the TSMS must address the means to be used to make 
electronic submissions. We have amended Sec.  138.505 to reflect this 
option.
    We received comments from a maritime company and an individual 
requesting more information regarding the address to which the results 
of an external audit are to be submitted to the Coast Guard.
    The Coast Guard agrees with these requests and has amended Sec.  
138.505 so that it is clear to the TPO which Coast Guard office or 
official external audit records must be submitted to. Also, we have 
inserted the address for the Coast Guard Towing Vessel National Center 
of Expertise.
    We received six comments from maritime companies requesting more 
information be provided regarding potential actions the Coast Guard may 
take if an owner is found to be noncompliant with the TSMS or 
requirements in subchapter M. Also, two commenters suggested that the 
TSMS is ``unenforceable'' and that we do not have a sufficient penalty 
process in place for violations.
    The company and its vessels are subject to a broad range of actions 
by the Coast Guard and the TPO depending on the conditions found on the 
vessel. Companies and vessels operating under a TSMS that fail to meet 
minimum requirements may be subject to enforcement, including Captain 
of the Port orders restricting operations, suspension and withdrawal or 
revocation of the COI, and suspension or revocation of the TSMS 
certificate. Also, as we state in Sec.  140.1000, violations of the 
provisions of this subchapter will subject the violator to the 
applicable penalty provisions of Subtitle II of Title 46, and the 
penalty provisions of Title 46, and Title 18, U.S.C.
    A company expressed concern about whether the Coast Guard would 
have resources to hire a sufficient number of competent vessel 
inspectors for convenient scheduling for the company, including drydock 
scheduling.
    Regarding having a sufficient number of competent vessel 
inspectors, as we indicated in response to comments above, the Coast 
Guard is prepared for what it has estimated will be the demand for 
annual inspection from owners and managing operators selecting the 
Coast Guard inspection option. The Coast Guard will closely monitor the 
demand for inspections and will make resource adjustments as necessary.
    Two maritime companies felt that use of any Coast Guard inspection 
resources should be based on risk and that those companies that have 
had satisfactory safety records, and successful TSMS audits, should not 
have the same level of Coast Guard oversight as companies with a 
history of poor performance.
    The Coast Guard agrees with the comment about its allocation of 
resources and intends to use a risk-based approach based on safety, 
survey, inspection and audit histories.
    One commenter requested information regarding how the Coast Guard 
will manage conflict of interest potentially created by future 
employment opportunities in the towing vessel industry offered to those 
conducting inspections. All Coast Guard personnel are bound by ethics 
laws and regulations which govern their ability to seek and accept non-
federal positions following their government service.
    One commenter urged the Coast Guard to obtain full jurisdiction 
over regulated towing vessels, including areas that OSHA is currently 
regulating.
    This request is beyond the scope of this rulemaking. OSHA will 
continue to enforce its requirements on shipyard employers that perform 
shipyard employment subject to 29 CFR 1915 on inspected and uninspected 
vessels. OSHA will also continue its current enforcement on uninspected 
vessels.
    A towing company suggested that a more ``streamlined'' TSMS be 
offered to smaller companies so as to avoid burdensome administrative 
requirements.
    A safety management system in general, and the TSMS in particular, 
is a flexible tool for management in that it is user-defined to address 
the unique operations, equipment and hazards present in the vessel 
operator's market. For the small business operator with a fleet of one 
or two vessels the TSMS may not need to be an expansive document. The 
requirements to identify the range of operations for a small towing 
vessel serving a limited area and market is likely to be much less than 
that of a larger towing vessel company consisting of dozens of vessels 
and serving a large, diverse market over a large area.
    The TSMS for small operators is scalable to their operation. Thus, 
it can be ``streamlined'' to address a limited set of assets, process, 
and personnel. As a towing vessel operation grows, so too would the 
TSMS need to scale up to identify the growing inventory of operations 
and accompanying safety concerns. We have not made any changes from the 
proposed rule based on these comments.
    One commenter suggested that the safety culture in the towing 
vessel industry could be further developed by addressing the 
communication barrier between managers and operation personnel.
    We believe the safety culture the commenter refers to will be 
greatly enhanced in companies with a TSMS in place. A TSMS is the 
central document that directly links the towing vessel and the shore-
based management operation. For a TSMS to be effective, management and 
operational personnel must continuously communicate. The TSMS documents 
processes, responsibilities and required action that define the

[[Page 40036]]

mutually supporting actions between managers and operation personnel. 
The Coast Guard believes that the integration of the TSMS will result 
in enhanced safety as it promotes greater communication and also 
defines corrective actions required when communications fail to produce 
the intended result of improving safety.
    One commenter suggested that for small companies that choose to 
elect the Coast Guard inspection option, language should be added to 
indicate that ``alternative compliance methodologies'' are acceptable.
    As we noted above, the Streamlined Inspection Program in part 8, 
subpart E, of this chapter, is an option that vessels subject to 
subchapter M may seek to use to renew a COI. Also, in Sec.  136.115, we 
proposed accepting certain alternative approaches to satisfying 
subchapter M requirements. We did not propose, however, to allow 
vessels subject to subchapter M to take advantage of part 8, subpart 
D's, Alternative Compliance Program to obtain a COI. We have made no 
changes from the proposed rule based on this comment.
    Another commenter suggested updating the Streamlined Inspection 
Program to include electronic, downloadable forms, and user-friendly 
templates.
    This suggestion is outside of the scope of this rulemaking. We made 
no changes from the proposed rule based on this comment.
    In the NPRM we discussed comments submitted in response to seven 
questions we posed in a December 30, 2004, Inspection of Towing Vessels 
notice. In response to that portion of the NPRM, one of these 
commenters recommended that all vessels should comply with the proposed 
SMS rules within 1 year. The same commenter suggested that using the 
ISM Code from 2002 as a guideline in developing the SMS requirements 
will allow for a number of operators using the AWO RCP to be compliant.
    Neither our proposed rule nor this final rule would require towing 
companies selecting the Coast Guard compliance option to establish a 
safety management system. This rule provides an option for towing 
companies to use the ISM systems currently published in 33 CFR part 96 
or other safety management systems acceptable to the Coast Guard under 
Sec.  138.225. The Coast Guard believes that we are providing 
sufficient flexibility for towing companies that want to adopt the 
safety management system option under subchapter M.
    We also received two comments on the proposed rule that opposed the 
TSMS. One stated that TSMS should not be the basis of any inspection 
regime and that any governmental inspection program should be staffed 
appropriately to provide for Coast Guard inspections, and asserted that 
having third party or other industry inspectors opens the door to 
profiteering or altered inspection requirements not originally intended 
by the regulations.
    The Coast Guard views subchapter M external and internal survey 
programs, combined with Coast Guard oversight of vessels and 
organizations choosing the TSMS option, as an effective means of 
helping to ensure compliance with subchapter M requirements. In 
addition, all vessels subject to subchapter M will be inspected by the 
Coast Guard before obtaining a COI and at least once every 5 years. See 
Sec. Sec.  136.210 and 136.212.
    Another commenter stated that TSMS is not necessary as an option 
because the Coast Guard can do the inspections as outlined in 
subchapter T (Small Passenger Vessels) which incorporates everything 
that is required in subchapter M. We disagree that subchapter T is 
appropriate for the unique nature of towing vessel operations, which is 
reflected in our authorization in 46 U.S.C. 3306(j) to establish an SMS 
``appropriate for the characteristics, methods of operation, and nature 
of service of towing vessels.'' We believe that a towing-vessel-
specific subchapter is appropriate, rather than imposing existing 
inspected vessel regulations on towing vessels. Towing companies that 
may lack the resources to develop and implement a TSMS, or choose not 
to, must follow the Coast Guard inspection option.

I. Third-Party Organizations (TPOs) (Part 139)

    We received several comments, mostly from maritime companies, 
requesting that the list of approved TPOs be made available online.
    The Coast Guard concurs with this recommendation and plans to 
publish a list of TPOs for the towing vessel industry to refer to when 
considering the selection of a TPO. The Towing Vessel National Center 
of Expertise (TVNCOE) will update and maintain the list and make it 
available at: www.uscg.mil/tvncoe.
    Other commenters requested that Sec.  139.120 be changed to include 
the name of the Coast Guard program office to which an organization 
seeking to become a TPO should submit its request.
    The Coast Guard agrees. We have amended Sec.  139.120 to identify 
the office and address of the TVNCOE, where such requests should be 
sent.
    One commenter expressed concern regarding the option offered by the 
wording of Sec. Sec.  139.115 and 139.120 for TPOs to create customized 
audit guidelines and tools. The commenter pointed out that the variety 
of audit reports could present inconsistencies during compliance 
checks.
    As proposed, part 138, subpart D, of this final rule requires that 
audits must be of sufficient depth and breadth to ensure the owner or 
managing operator meets the requirements outlined in Sec.  138.220. In 
our NPRM, we noted that an elaborate TSMS designed for large operations 
may be impractical for owners or managing operators with small 
operations, and that a small company may seek to use a significantly 
scaled down TSMS tailored to its operation. We acknowledge there will 
be variations in TSMSs. Similarly, we acknowledge that Sec. Sec.  
139.115 and 139.120 allows TPOs to develop customized audit guidelines 
and tools. The Coast Guard intends to issue guidance that may include 
sample checklists, job aids, and guides, but we have not changed 
Sec. Sec.  139.115 and 139.120 based on this comment because the 
requirements in part 138, subpart D, must still be met and we do not 
favor more prescriptive, one-size-fits-all standards in part 139.
    One commenter expressed confidence in the Coast Guard's ability to 
oversee the inspection of towing vessels conducted by classification 
societies. We received other comments expressing support for the use of 
qualified or trained third-party auditors and surveyors. Also, several 
maritime companies and a professional association supported Coast 
Guard's proposal to allow smaller entities, other than recognized 
classification societies, to apply for Coast Guard approval.
    Under proposed Sec.  139.110 a recognized classification society 
automatically would have met the requirements of a TPO for the purposes 
of part 139. However, as noted above, we have amended Sec.  139.110 to 
clarify the distinction between audits and surveys. A recognized 
classification society meets the requirements of a TPO for the purpose 
of performing audits. An authorized classification society meets the 
requirements of a TPO for the purpose of performing surveys. We did 
this to ensure the Coast Guard has evaluated the classification 
society's ability to carry out vessel surveys. We added a definition in 
Sec.  136.110 of ``authorized classification society'' for clarity. 
Paragraph (c) of Sec.  139.110 has been amended to specify that 
organizations qualifying as TPOs under paragraphs (a) or (b) of that 
section must

[[Page 40037]]

ensure that employees providing services under part 139 hold proper 
qualifications for the particular type of service being performed. We 
also note that the criteria stated in our TPO application section, 
Sec.  139.120, allow small entities to become TPOs. As we defined it, 
the term ``third-party organization'' is used to describe an 
organization approved by the Coast Guard to conduct independent 
verifications to assess whether TSMSs and towing vessels comply with 
applicable requirements contained in this subchapter.
    All auditors and surveyors approved to conduct subchapter M 
external surveys and audits would be part of a TPO. We set standards 
for auditors and surveyors in Sec.  139.130, but these are used in 
conjunction with Sec.  139.120 where we require TPO applicants to list 
the organization's auditors and surveyors who meet the requirements of 
Sec.  139.130. On further review of Sec.  139.130(a), the Coast Guard 
realized it makes sense to include ``surveyor'' in this lead paragraph. 
The specific qualifications for an auditor and a surveyor remain in 
paragraphs (b) and (c), respectively. We have edited this section 
accordingly.
    One commenter expressed concern that the requirements for TPOs 
would result in only classification societies qualifying to become 
auditors. The commenter was concerned that class society personnel are 
experienced in blue water shipping but not towing vessel operations.
    The Coast Guard developed this rule to ensure that organizations, 
including small entities, with the requisite knowledge, experience, and 
qualifications would be eligible to become a TPO. The standards in part 
139 allow organizations other than recognized classification societies 
to become TPOs, and meeting these standards should be within the 
capabilities of small entities seeking to provide such services to the 
towing industry.
    As qualified in our discussion above, Sec.  139.110 does not 
subject recognized or authorized classification societies to additional 
requirements for application as a TPO; however, as stated in Sec.  
139.110(c), their employees providing services under this part must 
have the proper qualifications in accordance with Sec.  139.130. The 
Coast Guard established this requirement to ensure that employees of 
recognized classification societies have the proper experience in 
towing vessel operations in order for them to carry out TPO audits 
under subchapter M.
    To help readers better understand that relationship, in the 
regulatory text of this final rule we have converted references to 
``approved third-party auditor'' or ``approved third-party surveyor'' 
to show this relationship--e.g., ``surveyor or auditor from a third-
party organization.'' Also, although we have left some difficult-to-
change instances in place, we avoid using the word ``approved'' with 
TPO because, as noted above, by definition a TPO is approved.
    We received several comments, particularly from maritime companies, 
supporting Coast Guard's oversight of third-party auditors and urging 
the Coast Guard to implement the approval process for third parties 
prior to the finalization of the rule. Commenters felt that the Coast 
Guard would need to ensure that a sufficient pool of third-party 
approvers is available prior to the increased demand created by 
subchapter M compliance.
    The Coast Guard is aware of the concern regarding the availability 
of third-party organizations. Subchapter M regulations governing third-
party organizations need to become effective before the Coast Guard 
will be able to evaluate requests from organizations seeking to become 
a TPO under part 139. That effective date is July 20, 2016. Also, on 
that date, in accordance with Sec.  139.110, recognized classification 
societies and authorized classification societies may begin acting as 
TPOs for the purpose of conducting subchapter M audits and surveys. As 
we noted above, we used a phased approach in our Sec.  136.202 
deadlines for obtaining a COI so as to distribute the work load over a 
6-year period from the effective date of this final rule.
    A commenter suggested that the Coast Guard publish a Navigation and 
Vessel Inspection Circular (NVIC) that provides the qualification 
process for TPOs.
    The Coast Guard plans to issue a guide to assist small entities, 
including those interested in becoming a third-party organization under 
subchapter M. However, we believe that part 139 is sufficiently 
specific. Section 139.120 identifies the information an organization 
would need to submit to become a TPO for purposes of subchapter M. We 
have amended Sec.  139.120 so it more precisely identifies where such 
requests should be sent. Section 139.130 includes a list of the 
qualifications of auditors and surveyors that those applying to become 
a TPO need to use to identify that organization's auditors and 
surveyors who meet these requirements. The Coast Guard will consider 
issuing guidance if it identifies wide-spread confusion after this rule 
is published.
    Some commenters, including maritime companies and trade 
associations, viewed the qualifications required for surveyors in Sec.  
139.130 as inadequate and recommended that the qualifications include 
sufficient background, training, and experience to qualify as a TPO. 
One of these commenters suggested that training for both auditors and 
surveyors should be provided by an independent accreditation 
organization. A commenter provided text edits to the language in 
proposed Sec.  139.130(b)(2) and recommended several minimum education 
requirements for auditors and surveyors.
    Section 139.130(c) already specifies a minimum level of education, 
skills, and experience needed for surveyors from TPOs. The ISO standard 
training requirement for auditors and the marine surveyor's 
accreditation requirement, as stated in Sec.  139.130, incorporate a 
role of independent accreditation organizations in the required 
training for both surveyors and auditors from TPOs. The Coast Guard 
feels that the criteria in Sec.  139.130, which lists qualifications of 
auditors and surveyors, provides a sufficient minimum level of 
education, skills and experience needed for third-party surveyors and 
auditors, and that we cannot point to evidence that higher-level-
education requirements would be justified. Owners, managing operators, 
and TPOs can establish additional requirements at their discretion.
    Some commenters suggested that the Coast Guard require surveyors to 
receive ISO 9000 series training.
    In Sec.  139.130 we include successful completion of an ISO 9001-
2000 or 9001-2008 lead auditor/assessor course or Coast Guard 
recognized equivalent qualification for auditors, but not surveyors. 
The Coast Guard does not believe that we should add training in ISO 
9001 standards as a required qualification for surveyors because 
surveyors conduct direct inspections of vessel equipment and systems as 
opposed to auditing SMS processes. In addition, the ISO does not have a 
9001 equivalent for surveying at this time.
    We received a comment requesting that existing qualified and 
certified inspectors that participate in an auditing program be 
``grandfathered'' as approved third-party inspectors.
    The Coast Guard does not intend to allow grandfathering of existing 
inspectors who may be participating in some form of an existing 
program. The Coast Guard has no oversight of these personnel and has no 
specified minimum qualifications for them to

[[Page 40038]]

conduct such work. If a person with qualifications required in Sec.  
139.130 wishes to conduct subchapter M TSMS audits or survey, he or she 
would need to start or become part of a TPO.
    We received requests for more information regarding the monitoring 
and removal process of auditors or third-party companies.
    In Sec.  139.145, we describe the process for a suspension of 
approval when the Coast Guard has determined that a TPO is not 
complying with the provisions of part 139. Under that process the Coast 
Guard will provide details to the TPO of the organization's failure to 
comply and provide a time period for the organization to correct its 
failure(s). In this final rule, we shorten Sec.  139.145 by replacing a 
repeated list of procedures the Coast Guard must follow for a partial 
suspension with a reference pointing back to the same procedures listed 
in paragraph (a) for a suspension.
    In Sec.  139.150, we make clear that the Coast Guard may revoke the 
approval of a TPO if the organization has demonstrated a pattern or 
history of failing to comply with part 139, substantially deviates from 
the terms of the approval granted under part 139, or has failures that 
indicate to the Coast Guard that the organization is no longer capable 
of carrying out its duties as a TPO. We amended Sec.  139.150, to 
provide provisions for Coast Guard notification to TPOs of actions 
taken under Sec.  139.150. In terms of monitoring, we note that Sec.  
139.160 lays out means for the Coast Guard to oversee TPOs.
    Two commenters requested more information regarding the reference 
to ``Required training courses for the auditing of a Towing Safety 
Management System'' in Sec.  139.130(b)(4).
    Paragraph (b)(4) of Sec.  139.130 in the proposed rule listed 
``[s]uccessful completion of a required training course for the 
auditing of a Towing Safety Management System'' as one of the 
qualifications in paragraph (b) an auditor must meet. Because auditors 
must meet all the qualifications listed in paragraph (b), we have 
deleted the redundant word ``required'' from paragraph (b)(4). Also, 
for added clarity and consistency we removed ``required'' from 
paragraph (b)(5)(ii) for the previously stated reason.
    Given the nature of the towing industry, the Coast Guard believes 
that auditors should complete a TSMS-specific auditing course. At the 
time of this writing, the Coast Guard is aware of at least one TSMS 
Auditor course and the Coast Guard believes that additional courses 
will be developed once this rule becomes effective, similar to the way 
courses developed for auditors of ISM-based safety management systems. 
We anticipate that market forces will meet the demand for TSMS-specific 
auditing courses.
    One commenter requested that the regulation be modified to only 
accept auditors that are U.S. citizens.
    The Coast Guard disagrees with this recommendation. This commenter 
did not provide reasons why we should make the requested change and we 
find no reason to base the eligibility for becoming an auditor in a TPO 
on citizenship. There are towing vessels operating overseas or in U.S. 
jurisdictions outside of the continental U.S. Requiring that an auditor 
be a U.S. citizen might unnecessarily limit the availability of 
auditors to these vessels. Also, a recognized classification society 
may operate around the world and is not required to employ only U.S. 
citizens.
    A commenter suggested that both auditors and surveyors must be 
accredited by an independent accreditation organization that is 
accepted by the Coast Guard and is organized especially for the purpose 
of accrediting auditors and surveyors to perform work in documenting 
compliance with subchapter M requirements for towing vessels. The 
commenter did not believe that the National Association of Marine 
Surveyors (NAMS), the Society of Accredited Marine Surveyors (SAMS), or 
another other organization should be allowed to accredit individual 
surveyors for purposes of subchapter M until the Coast Guard has 
approved the organization's accreditation processes. This commenter 
suggested the possibility that this accreditation process could also be 
done by an independent third-party auditor/surveyor accreditation 
organization that is accepted by the Coast Guard.
    We note that, that as with other organizations, NAMS and SAMS are 
not required to apply for approval to the Coast Guard to accredit 
individual surveyors. In Sec.  139.130, where we list qualifications 
for auditors and surveyors, we have removed paragraph (c)(4), which 
references accredited marine surveyors and NAMS and SAMS. Instead, we 
added ``accredited marine surveyor'' to a list of other relevant marine 
experience in paragraph (c)(2)(ii).
    These edits eliminate names of specific accrediting organizations, 
but still include work experience as an accredited marine surveyor as a 
factor to be considered and identified in applications. The Coast Guard 
believes that accreditation is a valuable factor to consider, but not 
an essential one--as reflected in the proposed rule which only required 
that qualifications from paragraph (c)(1) (education) and one of the 
two remaining paragraphs, (c)(2)(i) or (ii), be met. At this time, the 
Coast Guard does not see the need for it to accept an independent 
accreditation organization for the purpose of accrediting subchapter M 
auditors and surveyors.
    Some commenters recommended that the Coast Guard require that all 
TPOs provide and maintain a list of current and former auditors and 
surveyors.
    As we proposed in the NPRM, Sec.  139.135(a) of the final rule 
specifically requires TPOs to ``maintain a list of current and former 
auditors and surveyors.'' In Sec.  139.135(b), we remove the word ``for 
approval,'' but retained the requirement that to add an auditor or 
surveyor, the TPO must submit that person's experience, background and 
qualifications to the Coast Guard. We note that it is the 
responsibility of the TPO to ensure that auditors and surveyors 
conducting work for their organization satisfy the qualifications 
requirements in Sec.  139.130. The submissions required by Sec.  
139.135(b) will assist the Coast Guard in its continual oversight of 
TPOs.
    A State government and a task force suggested that the Coast Guard 
consider developing a TPO-rating criterion that is based on the 
percentage of towing vessel companies (for which the TPO has issued a 
TSMS certificate) that the Coast Guard independently finds to have 
major non-conformities. If the number of companies in a given period 
having major non-conformities exceeds that percentage, the TPO should 
be automatically placed on the a ``grey list,'' and be required to 
demonstrate to the Coast Guard that it is taking actions to improve its 
oversight/auditing program. The commenters felt that this criterion 
would help vessel owners and operators assess the qualification of its 
oversight program.
    The Coast Guard will consider this recommendation after it gains 
experience with the implementation of these rules when developing 
metrics for evaluating and overseeing TPOs.
    Two commenters expressed concern that a company may switch TPOs to 
find one that enforces compliance with subchapter M less rigorously. 
These commenters suggested that the Coast Guard develop a criterion to 
prevent towing vessel companies from ``third-party organization 
hopping,'' such as a provision that if a towing vessel company changes 
TPOs more than once in a 5-year period, an external Coast Guard 
inspection of the company's

[[Page 40039]]

TSMS documents and vessels is automatically triggered.
    The Coast Guard acknowledges that a company may seek to switch its 
TPO for the reason suggested, but a company may also change its TPO for 
reasons beyond its control or for reasons other than seeking to avoid 
full compliance with subchapter M. Because switching TPOs is not 
necessarily a reason to focus more attention on a given company, the 
Coast Guard would be reluctant to adopt the more-than-once-in-5-years 
metric suggested by the commenters, but it does acknowledge that 
changing TPOs could be a signal that more scrutiny should be focused on 
a company. We note that the monetary costs and the loss of time 
associated with such changes will be factors a company would consider 
before switching to a different TPO, and therefore we do not expect TPO 
switching to be a common occurrence.
    Referencing Sec. Sec.  139.120 and 139.155, a commenter noted that 
the NPRM does not specify a process for a company to follow if it needs 
to appeal a decision of its TPO to deny or revoke issuance of a TSMS 
certificate. The commenter also noted that the Coast Guard must create 
a specific appeals process because towing vessel companies with a TSMS 
are dependent on third-party documentation to obtain a COI. The 
commenter wrote that the proposed rule required third parties to 
develop procedures for appeals, and allows a company to follow 
existing, general appeals procedures, but that more detail is needed.
    The Coast Guard has provided a specific appeal process in this 
final rule. As reflected in above, in Sec.  136.180 we stated that any 
person directly affected by a decision or action taken under this 
subchapter by or on behalf of the Coast Guard, may appeal in accordance 
with subpart 1.03 in subchapter A of this chapter. We have added Sec.  
1.03-55 to identify the Coast Guard official or office appeals should 
be directed to, including the appeal of matters relating to action of a 
third party, such as when a third party rescinds a TSMS certificate.
    A commenter expressed concern regarding a potential conflict of 
interest for companies that develop TSMSs or provide TSMS-related 
training sessions. The commenter said that such a company would not be 
able to objectively inspect systems that they developed because finding 
fault with the towing company would be a reflection on their own work. 
Moreover, this commenter saw a related potential conflict of interest 
resulting if the only companies that could be hired to conduct surveys 
and audits were those that didn't develop the TSMS. In that situation, 
the commenter noted, it may be the developer's direct competitor who is 
hired as the TPO and that competitor would have a natural tendency to 
be biased against programs that look different from the ones it 
produces.
    Section 139.120(o) requires TPO applicants to disclose any 
potential conflicts of interest. Section 139.120(p) requires applicants 
to submit a statement to the Coast Guard stating that their employees 
who are engaged in audits and surveys will not engage in any activities 
that could result in a conflict of interest, which we define in Sec.  
136.110, or that could otherwise limit the independent judgment of the 
auditor, surveyor, or organization. And under Sec.  139.150(a)(3), 
conflicts of interest are a factor the Coast Guard may consider when 
deciding whether to revoke the approval of a TPO. An organization does 
not have to be a TPO to develop or help implement a TSMS, but a TPO is 
the only entity that can verify compliance with a TSMS or issue a TSMS 
certificate.
    One company stated that an organization should be assigned to 
oversee the third-party process in order to ensure consistency in the 
use of resource materials and tools. Another commenter asked what 
process would be in place to oversee TPO training and approvals.
    As reflected in the NPRM and this final rule, the Coast Guard will 
provide direct oversight of TPOs. A list of Coast Guard oversight 
activities appears in Sec.  139.160. This oversight is intended to 
ensure that TPOs that conduct audits and surveys for towing vessels 
subject to this subchapter comply with part 139 requirements. To the 
extent consistency in the use of resource materials and tools by TPOs 
is required by part 139, the Coast Guard will provide the oversight 
requested. To the extent it is not, we view the requested oversight as 
an area best left to market forces. In reviewing proposed Sec.  
139.160(g), which discussed the Coast Guard being able to require a 
replacement for noncompliance or poor performance, we deleted that 
paragraph because it is covered by suspension provisions in Sec.  
139.145(b).
    We received a comment from a towing company that felt that because 
of limited Coast Guard resources, relying on third-party auditors would 
be a solution to the increase in demand for inspections after 
implementation of subchapter M.
    We concur that the use of TPOs under the TSMS option may reduce the 
number of Coast Guard inspections required to implement subchapter M.
    We received comments from towing companies and professional 
associations that suggested that TPO requirements in proposed Sec.  
139.160(f) and (g) be moved to Sec.  138.510 because of the discussion 
of owner and managing operator compliance oversight of TSMS. One 
commenter suggested that Sec.  139.160(f) be moved under Sec.  138.400.
    The Coast Guard disagrees with these recommendations. Section 
139.160 lists discretionary oversight activities the Coast Guard 
employs in its oversight of TPOs. These oversight activities should not 
be moved under Sec.  138.510, which describes the Coast Guard's 
authority to direct owners, managing operators, and third parties to 
explain or demonstrate portions of the TSMS when there is evidence that 
the TSMS is not in compliance with part 138 requirements, nor under 
Sec.  138.400, which addresses audits of safety management systems. We 
did remove Sec.  139.160(g), however, because it is covered by 
suspension provisions in Sec.  139.145(b), and we also removed proposed 
paragraph (c) because there was no need for us to refer to assigning 
personnel to observe or participate in audits or surveys.
    A commenter suggested that the Coast Guard open communications with 
stakeholders to become better informed of options to ensure consistency 
in the auditing process.
    The Coast Guard established the TVNCOE in 2010 to help promote 
consistency in the regulation of towing vessels and to promote 
communications between the Coast Guard and industry as we moved towards 
certification of towing vessels. The TVNCOE communicates routinely 
through their national customer service representatives, list server, 
and Web site (http://www.uscg.mil/tvncoe) with those who will be 
subject to subchapter M requirements. As the Coast Guard approving 
authority for TPOs, TVNCOE will have oversight responsibilities to 
assure consistency with the auditing process.
    One commenter said that the Coast Guard needs to ``assure the 
integrity'' of the third-party approval system.
    The Coast Guard expects that by using a single entity, the TVNCOE, 
to review and approve TPOs, the Coast Guard will ensure consistency and 
integrity in the subchapter M TPO system.
    A commenter felt that in the context of part 139, it is not clear 
if a third-party auditor needs to be associated with a TPO or if an 
auditor can be approved as an independent operation.
    The Coast Guard notes that to perform external audits under 
subchapter M, the

[[Page 40040]]

auditor must be listed by a TPO as one of its auditors who meets the 
requirements of Sec.  139.130. This individual need not be exclusively 
employed by a single TPO. It would be possible for a single auditor--
who worked in a remote location, for example--to work for more than one 
TPO. As previously mentioned, the Coast Guard has revised language in 
this final rule to make it clear that under subchapter M, external 
surveys and audits must be conducted by auditors and surveyors who are 
part of--and subject to oversight by--a TPO.
    An individual noted that part 139 does not contain procedures on 
how to conduct a damage survey of a vessel.
    Part 139 deals with TPOs and would not contain requirements 
relating to a damage survey. Surveys are generally discussed in part 
137. Section 137.300(b) discusses an OCMI's ability to require further 
examination of the vessel in the event of damage. In addition, if the 
vessel is damaged, Sec.  136.240 addresses how to obtain permission to 
proceed for repairs. The extent of a given vessel's damage and other 
circumstances may warrant specific survey requirements.
    One towing company suggested the need for a peer auditing program 
to assess consistency and competency among TPO auditors and surveyors.
    TPOs will be required to adhere to ISO 9001 standards for operating 
in accordance with a Quality Management System, and their auditors must 
have completed training in ISO 9001 Quality Management Systems 
Auditing. We list ``accredited marine surveyor'' in Sec.  139.130, 
along with other-relevant-marine-experience, as a non-mandatory 
qualification for surveyors.
    We do not agree with the commenter that supplemental peer-review of 
TPO auditors and surveyors is warranted or necessary. We note that the 
work of surveyors will be subject to audits, and as noted above in our 
discussion of Sec.  139.160, the Coast Guard will be overseeing the 
work of TPOs.
    An individual argued that the intent of the term ``third party'' is 
to explain that the Coast Guard is a third party to towing vessels and 
the term should not apply to the organizations to which the Coast Guard 
is delegating authority.
    The Coast Guard does not use the term ``third party'' in the way 
suggested by this commenter. We use the term to refer to a TPO, which 
we define as ``an organization approved by the Coast Guard to conduct 
independent verifications to assess whether towing vessels or their 
TSMSs comply with applicable requirements contained in this 
subchapter.'' As previously noted, we have made changes to clarify our 
third-party references in this rule, but we have made no changes from 
the proposed rule based on this comment.
    As noted above in our discussion of comments related to part 138, 
we removed Sec.  139.170 because those attendance provisions are 
already stated in parts 137 and 138.

J. Operations (Part 140)

    We received many general comments from individuals, companies, and 
associations concerning our operational requirements in part 140.
    Two commenters noted that the purpose section of part 140 does not 
explain how the Coast Guard will ensure that non-TSMS operating 
companies comply with the regulations because these companies do not 
have documented written procedures and are not subject to audits. One 
commenter expressed concern that non-TSMS companies would have lower 
operation costs and their services would be less safe.
    In the NPRM, the Coast Guard offered the TSMS or Coast Guard annual 
inspection option. For vessels that do not choose the TSMS option, we 
will use Coast Guard inspections to verify compliance with the 
requirements of this subchapter. We are confident that the Coast Guard 
annual inspection option will help to ensure that towing vessels are 
operated at an appropriate level of safety. The casualty reviews 
presented in the benefits chapter of the Regulatory Analysis found many 
instances in which the Coast Guard inspection and TSMS options were 
rated the same in risk reduction benefits and other cases where the 
TSMS options scored higher. If a company believes the Coast Guard 
inspection option is more cost-effective than a TSMS, this rule 
provides the flexibility for that choice. We have made no changes from 
the proposed rule based on this comment.
    In reviewing Sec.  140.200, and similar sections in parts 141 
through 144 which state that if a TSMS is applicable to the vessel it 
must have provisions for compliance with that part, we decided to 
delete those sections. They are unnecessary because part 138 addresses 
what the TSMS must cover regarding all subchapter M requirements.
    A company noted that the list of mariners required to have a 
Transportation Worker Identification Credential (TWIC) by Sec.  
140.205(e)'s reference to 33 CFR 101.105 is too broad and should 
instead be the same requirement as under 33 CFR 101.515. Further, an 
individual noted that the rule did not have language explaining the 
requirement for TWIC cards for individual employees on vessels moving 
certain dangerous cargo.
    In part 140, subpart B, which includes Sec.  140.205, we do require 
that the vessel be operated in accordance with applicable laws and 
regulations, but there is no explicitly stated requirement for 
personnel to hold a TWIC. The Coast Guard understands the problem with 
Sec.  140.205(e)'s reference to 33 CFR 101.105, and in the final rule 
we removed that reference and replaced it with the personal 
identification requirements of 33 CFR 101.515--which do not require 
personnel to have a TWIC.
    One commenter suggested that complete background checks for 
employees should not be required for those crewmembers who are required 
to obtain a TWIC.
    The Coast Guard notes that in general a background check is 
included as part of receiving a TWIC, and we also note that we are not 
requiring background checks in these regulations.
    Regarding a Master's authority on board, an individual suggested 
that proposed Sec.  140.210 ensure that the TSMS contains a clear 
statement emphasizing the master's authority.
    The Coast Guard proposed in Sec.  140.210(b) that the master must 
take adequate corrective action or cease operations when he or she 
believes that an unsafe condition exists. Moreover, Sec.  140.210(c) 
further states that the master has the authority to take steps deemed 
necessary and prudent to assist vessels in distress or for other 
emergency conditions. The Coast Guard believes that these requirements 
are sufficient to provide the master of the vessel the appropriate 
latitude and discretion to exercise his or her duties to ensure the 
safety of the vessel. In reviewing Sec.  140.210, we have added the 
officer in charge of a navigational watch as also having the 
responsibility to cease operation or take adequate corrective action if 
he or she believes it is unsafe for the vessel to proceed. Also, we 
amended Sec.  140.210(d) to indicate that the crew must ensure that 
either the master or the officer in charge of a navigational watch is 
made aware of the vessel's condition. And in Sec.  140.605 we moved a 
requirement into paragraph (a) that was covered by proposed paragraph 
(c) and added ``or officer in charge of a navigational watch'' in the 
discussion of determining if the vessel meets all stability 
requirements before getting underway. We made similar revisions to the 
requirements for master or officer in charge of a navigational watch in 
Sec. Sec.  140.610(c) (hatches and openings) and 140.615(b) (tests and 
examinations).

[[Page 40041]]

    One commenter felt that if the language in Sec.  140.210(d) is 
intended for crew members who are responsible for maintaining a 
vessel's COI, then the Coast Guard should require that the vessel's 
TSMS contain a provision requiring that crew members receive training 
on how to complete the tasks assigned to them by the TSMS and how to 
comply with the COI.
    The Coast Guard proposed in Sec.  138.220(b)(2)(ii) that the TSMS 
contain a policy relating to training personnel in ``duties associated 
with the execution of the TSMS.'' The Coast Guard believes that this 
requirement is sufficient to ensure that crew members are aware of 
their duties under the TSMS. We have made no changes from the proposed 
rule based on this comment.
    A company suggested that the term ``pilot'' would be more 
appropriate instead of ``mate'' in Sec.  140.210(c). Another commenter 
suggested that ``mate (pilot)'' be deleted from Sec.  140.210(c) 
because its current use suggested that the mate and master were equal, 
rather than the master having the ultimate authority on the ship. 
Alternatively, the commenter suggested that language be added to Sec.  
140.210(c) stating that the mate must inform the master before 
deviating from the COI if time and circumstances permit.
    The Coast Guard recognizes that throughout the diverse towing 
industry there are differences in terminology, including in the use of 
``pilot'' or ``mate.'' For purposes of consistency with other sections, 
the Coast Guard has chosen to use the terms ``master or mate (pilot)'' 
in this rule, or ``officer in charge of a (or the) navigational watch'' 
as appropriate, as they are the most common currently applied terms in 
related regulations and policy, including manning regulations in 46 CFR 
part 15. The Coast Guard does not agree with the comment about ``mate 
(pilot)'' because we are simply referring to the responsibility of the 
person in charge of the navigational watch. The Master retains overall 
responsibility for the safety of the towing vessel as prescribed in 
Sec.  140.210(a). We have made no changes from the proposed rule based 
on this comment.
    We received two comments suggesting the development of a policy to 
restrict the use of cell phones and other non-essential electronic 
devices by pilothouse watchstanders.
    The Coast Guard has added language in Sec.  140.210(d) requiring 
the crew to minimize distractions when performing duties. This 
amendment is intended to prevent the non-essential use of cell phones 
and other distractions that take away from a crewmember's situational 
awareness. Given the commenters' focus on pilothouse watchstanders, we 
have amended Sec.  140.640 to expressly require the officer in charge 
of a navigational watch to maintain situational awareness and minimize 
distractions.
    We received two comments suggesting that either the word 
``lookout'' be deleted from Sec.  140.400(c), or that the word be 
changed to the phrase ``supplemental lookout.'' They argued that the 
term ``lookout'' was superfluous because the master or mate serves as 
his or her own lookout.
    The Coast Guard is requiring in Sec.  140.400 that a record be 
maintained for all watchstanders going on and off watch. Lookouts are 
added by the master or mate (pilot) under the provisions of Sec.  
140.630. This does not preclude the Master or Mate (Pilot) from acting 
as a lookout, when appropriate. Section 140.400 requires that lookouts 
and all other members of the navigation watchstanding team must have 
times of service entered and recorded. Our addition of ``officer in 
charge of a navigational watch'' to the list of watchstanders does not 
change our need to include lookouts.
    We received comments from an individual and an association who 
recommended that the Coast Guard should require that any mariner, 
engineer, or watchstander that works in the engine room, or near 
machinery, be provided with initial safety training and additional 
training on the operation and maintenance of installed machinery prior 
to beginning work in these areas.
    In Sec. Sec.  140.410(b)(10) and 140.515, the Coast Guard 
specifically requires safety orientation training on the awareness of 
and expected response to any hazards inherent to the operation of the 
towing vessel which may pose a threat to life, property, or the 
environment. Section 15.405 of 46 CFR requires that crewmembers be 
familiar with the relevant characteristics of the vessel prior to 
assuming their duties and responsibilities, including the main 
propulsion and auxiliary machinery, such as steering gear systems and 
controls. We have amended Sec. Sec.  140.405 and 140.410 to note that 
personnel must meet the requirements in Sec. Sec.  15.405 and 15.1105 
as appropriate. In Sec.  140.405, we also added threats to the 
environment during an emergency as situations when the duties and duty 
stations of each person onboard must be identified; this amendment is 
consistent with general vessel operation objectives stated in Sec.  
140.205(a).
    Under Sec. Sec.  140.510 and 140.515, it is the responsibility of 
the owner or managing operator to identify the unique training required 
to mitigate the risk to the specific machinery and operating equipment 
aboard each particular towing vessel.
    Several commenters suggested that proposed Sec.  140.415 include 
the following text in the ``reserved'' paragraph: ``A safety 
orientation need not be provided to an individual that is not a 
crewmember if that individual is accompanied while on board the towing 
vessel by a crewmember who is familiar with the items specified in 
Sec.  140.415(a).''
    The Coast Guard does not agree. The Coast Guard believes it is 
unreasonable to assume that during an emergency the escorting crewman 
would have no other responsibilities or duties other than escorting the 
individual at all times while aboard the vessel. The Coast Guard 
believes that a safety orientation for individuals visiting the vessel 
would not place an undue burden in terms of time or distraction. The 
Coast Guard has made no changes from the proposed rule based on these 
comments. However, note that for simplicity we have removed the 
``reserved'' paragraph, made the previous paragraph (a) into 
introductory text, and made the previous subparagraphs of (a) into 
paragraphs (a) through (d), as appropriate.
    One commenter asked for clarity regarding specific drills and 
training that would be required in Sec.  140.420(a), and thought that 
the requirement of drills to respond to ``other threats to life, 
property, or the environment'' was too ambiguous. Another noted that 
additional requirements for first-aid trainings should be included in 
the regulation.
    The Coast Guard in Sec.  140.420(a) provided specific emergency 
drills that must be performed. This includes abandoning the vessel, 
recovering persons from the water, responding to onboard fires and 
flooding, or responding to other threats to life, property, or the 
environment. The owner or managing operator is responsible for 
identifying any other additional training and drills required in 
addition to the above identified requirements based on the specific 
intended service of their vessels. This may be covered by the required 
risk assessment for TSMS vessels.
    The Coast Guard has made no changes from the proposed rule based on 
these comments.
    We received a recommendation for text additions to proposed Sec.  
140.420 that included the option for ``e-learning'' for emergency 
drills and trainings. The commenters suggested that the Coast Guard not 
require follow-

[[Page 40042]]

on discussions with a subject matter expert if the ``e-learning'' 
provides scoring at the completion of training and the individual 
receives a score higher than the minimum required by the TSMS.
    The Coast Guard in Sec.  140.420(e) specifically provides for 
alternative forms of instruction for the training aspect of Sec.  
140.420; however, the participation in emergency drills must take place 
on board the vessel so far as practicable. This section permits 
training required by this rule to be conducted by viewing 
electronically or digitally formatted training materials followed by a 
live discussion led by someone familiar with the subject matter. The 
Coast Guard believes that follow-on discussions with members of the 
crew and interactive discussions provide insights into the specific 
functions of emergency procedures aboard a particular ship and allow 
crew members to individually and collectively discuss specific actions 
and expectations of each other during drills or actual emergencies. 
Further, to ensure that the alternative form of instruction is 
sufficient, we amended Sec.  140.420(e) by adding requirements that a 
competent individual provide a demonstration using equipment that is 
the subject of the training.
    We received several comments on Sec.  140.420(d). An individual 
noted that ``rescue boat'' was not defined in Sec.  136.110. The 
commenter questioned whether the Coast Guard was using the terms 
``skiff'' and ``rescue boat'' synonymously in Sec.  140.420(d) and 
requested that the Coast Guard define ``rescue boat'' if ``rescue 
boat'' and ``skiff'' were intended to be different vessels. Another 
commenter felt that requiring a safety orientation for crewmembers to 
be conducted annually as proposed in Sec.  140.420(d)(1) was 
unnecessary and burdensome.
    The Coast Guard recognizes ``skiffs'' and ``rescue boats'' as 
different types of vessels and did not use them interchangeably in 
Sec.  140.420(d). The Coast Guard agrees that ``rescue boat'' should be 
defined and has amended Sec.  136.110 to provide a definition.
    As for the second comment, the Coast Guard agrees and has removed 
proposed Sec.  140.420(d)(1), which contains the requirement for an 
annual safety orientation. The requirements for when a safety 
orientation should be conducted can be found in Sec.  140.410(b). The 
Coast Guard has amended that paragraph to clarify that a safety 
orientation is required for a crewmember prior to that crewmember 
getting underway for the first time on a particular towing vessel. 
Also, in Sec.  140.410(c) we corrected a reference to ``new vessel,'' 
by switching it to ``other vessel'' regarding requirements for safety 
orientation provided to crewmembers who received a safety orientation 
on another vessel. Furthermore in Sec.  140.410(d) we amended paragraph 
(d)(3) to require the signature in addition to name of those providing 
training.
    In reviewing Sec.  140.420(d), we added paragraph (d)(5) which 
states that credentialed mariners holding an officer endorsement do not 
require the instruction listed in paragraph (d) with the exception of 
launching a skiff, if one is listed as an item of emergency equipment 
to abandon ship or recover persons overboard. We added a similar 
provision in Sec.  140.645(c) for credentialed mariners holding Able 
Seaman or officer endorsements regarding navigation safety training 
requirements in Sec.  140.645. These changes allow credentialed 
mariners to use their previous training to meet specified subchapter M 
training requirements.
    One commenter suggested that the term ``work vests and anti-
exposure work suits'' be used instead of ``work vest'' in Sec.  140.430 
because anti-exposure work suits are also approved under 46 CFR 
160.053.
    The Coast Guard does not agree with this suggestion. Vessel 
personnel are afforded three choices of approved equipment that they 
may use. In Sec.  140.430 the Coast Guard addresses the wearing of work 
vests and states that life jackets, immersion suits, and work vests 
must all meet applicable regulations. The term ``anti-exposure work 
suit'' does not appear within 46 CFR subpart 160.053. The Coast Guard 
has made no changes from the proposed rule based on these comments.
    We received several comments requesting that Sec.  140.430 permit 
type III Personal Flotation Devices (PFD) as an alternate to work 
vests. One commenter requested that work vests worn at night not 
require a light.
    Section 140.430 provides the standard requirements for the wearing 
of work vests; however, companies can require the use of approved 
flotation devices that are of a higher type rating. The Coast Guard 
does not agree with the comment requesting the removal of the lighting 
requirement for work vests worn at night as this is an important safety 
feature for night time operations. We note that we did amend a 
reference in Sec.  140.430 to a paragraph in Sec.  141.340 based on 
amendments we made in Sec.  141.340; we changed the paragraph reference 
from ``(c)'' to ``(g)(1).''
    We received several comments opposing the requirement in Sec.  
140.435(b) and (c) for small crews and low-risk environments to 
maintain automatic external defibrillators (AEDs) on board towing 
vessels. Commenters, including maritime companies, felt the proposed 
requirement should be removed because subchapter T, which applies to 
vessels in higher risk environments, does not require AEDs. Others felt 
that the cost of the equipment and training would be a burden on small 
companies. A maritime company requested that harbor boats be exempted 
from the requirement because of the emergency response personnel and 
land-based assistance available. Also, we received several comments 
that supported the requirement and need for AEDs on towing vessels. An 
individual suggested clarifying that the intent of the requirement is 
for vessels that are ``double crewed'' and not those containing 
``overnight accommodations.'' Two commenters suggested that the 
training for AED use should be left to the manufacturer's 
recommendations.
    Due to the comparatively high cost of the carriage (estimated by 
the Coast Guard at $2,500 per unit for each vessel), maintenance, and 
training of AEDs on board towing vessels, the Coast Guard has decided 
to remove the AED requirements proposed in Sec.  140.435(b) and (c). 
However, companies can elect to carry, maintain, and train crews on 
equipment above and beyond the scope of subchapter M requirements. 
Owners and managing operators can address AED carriage using a risk-
based approach through the requirement to implement procedures to 
identify and mitigate health and safety hazards in Sec.  140.510.
    We received some comments on safety concerns that were not included 
in the NPRM. Two commenters noted that the NPRM does not include the 
safe remediation of asbestos and suggested either referencing OSHA 
regulations or other related code in the rulemaking or drafting our own 
regulations and adding them to the rulemaking. A commenter also 
expressed concerns regarding carbon monoxide exposure from exhaust 
leaks in the towing vessels and suggested that the Coast Guard include 
guidance on protection against carbon monoxide exposure.
    Another commenter suggested that the Coast Guard implement a ``No 
Smoking'' policy for mariners. The same commenter and an individual 
requested that Coast Guard institute hearing protection programs as 
well. Similarly, a commenter suggested that the Coast Guard implement 
additional occupational safety and health

[[Page 40043]]

regulations to protect mariners from accidental injury or death.
    Another commenter said that the regulations should incorporate 
effective means of ``severing or releasing'' a chain or wire rope tow 
connection in the case of emergencies, noting that a fire axe cannot 
effectively cut such towline. Lastly, two commenters provided several 
suggestions for additional workplace safety regulations such as 
preventive maintenance programs, the incorporation of the OSHA personal 
injury reporting system instead of CG-form 2632 for personal injury 
reporting, and a hearing protection program for mariners comparable to 
OSHA standards for shoreside workers.
    With regard to mariner safety, the Coast Guard is committed to the 
safe operation of vessels and the protection of mariners. Section 
140.510 establishes the requirements for owners or managing operators 
to implement procedures to identify and mitigate health and safety 
hazards aboard towing vessels subject to inspection, which can include 
exposure to asbestos, smoking, noise, carbon monoxide, and the ability 
to sever or release wire or chain towlines. Regarding the comment on 
the use of the CG-2692, this rule implements a casualty reporting 
regime consistent with the requirements for other classes of inspected 
vessels. Further, this final rule requires that the owners and 
operators of these vessels develop and implement their own health and 
safety processes and procedures--see subpart E of part 140. The OSHA 
standards for shoreside workers could be used as a template for this 
purpose. The Coast Guard has made no change from the proposed rule 
based on these comments.
    Finally, the Coast Guard disagrees with the comments regarding the 
incorporation of OSHA standards. As we noted in the NPRM, OSHA's 
jurisdiction on the workspace safety aspects for seamen on towing 
vessels subject to subchapter M will cease. However, we have endeavored 
to incorporate some of the OSHA requirements into the Health and Safety 
Plan requirements in the final rule. A commenter's recommendation that 
Congress transfer certain authority from OSHA to the Coast Guard is 
beyond the scope of this rulemaking.
    We received numerous comments that objected to proposed Sec.  
140.520, which would require the owner or managing operator to maintain 
and provide access to medical records. Several commenters suggested 
that this section be deleted because medical recordkeeping is not 
required in subchapter T. Other commenters also felt that Sec.  140.520 
conflicted with the Health Insurance Portability and Accountability Act 
of 1996 (HIPAA), Public Law 104-191, and should be deleted in its 
entirety, because under HIPAA employers do not retain medical records 
on employees containing diagnoses that those employees have not already 
seen. One commenter suggested that Sec.  140.520(b) be deleted because 
it conflicted with the patient's right to know and violated HIPAA. 
Another commenter suggested that the section be revised to emphasize 
medical records confidentiality requirements that currently exist in 
Federal law. One commenter felt that the section should clarify what 
information an employer can give out under HIPAA. One commenter 
questioned which medical records need to be retained under Sec.  
140.520(a). Finally, another commenter suggested we amend Sec.  
140.520(a)(1) so as to require that only medical records related to 
pre-employment physicals, injuries occurring in the course or scope of 
employment, or medical procedures required by the employer be 
maintained.
    The Coast Guard agrees in principle with the comments and deleted 
proposed Sec.  140.520 from the final rule. The intent of the 
requirement was to ensure that owners or managing operators retain 
records of injuries occurring in the course or scope of employment as a 
result of a health and safety incident on board the vessel. However, we 
believe the health and safety plan required under Sec.  140.500 already 
includes recordkeeping procedures addressing this issue. Also, we have 
amended Sec.  140.505(a) to make clear that the owner or managing 
operator must maintain records of health and safety incidents that 
occur on board the vessel, including any medical records associated 
with the incidents, and that upon request, he or she must provide 
crewmembers with incident reports and the crewmember's own associated 
medical records.
    One commenter suggested that the Coast Guard establish food 
sanitation regulations in the final rule and felt that sanitation 
regulations, including food sanitation, should be enforced with 
recognized standards using an inspection checklist. The Canada Shipping 
Act was cited as an example.
    The Coast Guard does not agree that additional regulations are 
required in the final rule to address the issues of food sanitation 
aboard towing vessels. As we proposed, this rule requires that the 
owner or managing operator of the towing vessel to establish policies 
regarding sanitation and safe food handling. These requirements may be 
found in Sec.  140.510(a)(13). Additionally, the Coast Guard has the 
authority during normal inspection activities to issue corrective 
action orders to a towing vessel to improve any unsafe condition, 
including unsanitary food conditions, and under Sec.  137.220, the 
owner or managing operator of a towing vessel that has selected the 
TSMS option must examine or have examined systems, equipment, and 
procedures to ensure that the vessel and its equipment are suitable for 
the service for which the vessel is certificated, including being in 
compliance with part 140 of this subchapter. The Coast Guard has made 
no change from the proposed rule based on this comment.
    A professional association noted that the potable water supply for 
vessels should be maintained at the same quality as for the Coast 
Guard's military and civilian employees. The commenter suggested that 
the Coast Guard issue regulations in this rulemaking that are 
reasonable and attainable by towing vessels. Two commenters suggested 
that if the water supply aboard a vessel does not satisfy tests for 
quality and purity the vessel owners must provide bottled water for the 
crew members.
    The Coast Guard agrees that the condition of water supply aboard 
towing vessels should be of a sufficient quality that the members of 
the crew are not endangered. Under 46 U.S.C. 3305(a)(1)(D), the 
inspection process ensures that vessels subject to inspection have an 
adequate supply of potable water for drinking and washing. In the NPRM, 
the Coast Guard proposed a requirement in Sec.  140.510(a)(13) for the 
owner or managing operator to implement procedures to identify and 
mitigate health and safety hazards regarding sanitation and safe food 
handling. Having an inadequate supply of safe water for sanitation 
purposes and for food handling is to be addressed by the owner or 
managing operator. To ensure that potable water is expressly addressed 
in Sec.  140.510, and that there is an adequate supply of potable water 
for drinking, we have added a potable water supply requirement as Sec.  
140.510(a)(14).
    One commenter felt that the proposed requirements in Sec.  
140.515(b) for training for individuals, other than crew members, 
should include more specifics on the information or training required, 
such as fire training and abandon-ship training. Another commenter 
suggested that the refresher training in Sec.  140.515(d) be repeated 
every 5 years, rather than annually, because annually was excessive.
    The Coast Guard does not agree that additional information on the 
information and training required for

[[Page 40044]]

persons aboard towing vessels other than crew members is required in 
this rule to address the commenter's concerns. In Sec.  140.415, the 
Coast Guard requires that individuals who are not crewmembers on board 
towing vessels must receive additional safety orientation prior to 
getting underway or as soon as practical thereafter to include issues 
of use of life-saving equipment, emergency procedures, emergency 
communications with crewmembers in case of an emergency, and prevention 
of falls overboard. Under Sec.  140.515(b), the Coast Guard requires 
owners or managing operators to identify, specific to their towing 
vessel's operations, what other information or training is needed to 
limit the exposure of individuals to hazards onboard the vessel.
    The Coast Guard believes that annual refresher training is 
necessary but, as reflected in Sec.  140.515(d), the refresher training 
does not need to be as in-depth as the initial training. These annual 
training requirements parallel or mirror comparable OSHA requirements 
which currently apply to uninspected towing vessels. Companies have the 
ability to tailor this training to be less comprehensive based on the 
risk. We made no changes from the proposed rule based on these 
comments.
    We received comments from individuals and companies who felt that 
the proposed requirement in Sec.  140.610 to close all exterior 
openings on the main deck is not feasible when vessels require 
ventilation during hot weather, and not necessary in low water where 
there is no current.
    Others contended that stability is not an issue on inland 
waterways, and that there should be no stability requirements for 
Western Rivers towing vessels.
    The Coast Guard believes that watertight integrity and stability is 
a concern on any vessel, regardless of service or operating area. 
Towing vessels must be maintained and operated so the watertight 
integrity and stability of the vessel is not compromised. There is a 
sufficient body of historical evidence regarding towing vessel 
casualties in which the cause of the casualty was the lack of 
watertight integrity of the towing vessel. Specifically, open hatches 
have permitted the uncontrolled ingress of water into the towing 
vessel, resulting in the vessel sinking.
    Within their final report on ``Recommendations for the Enhancement 
of Towing Vessel Stability'' dated September 9, 2013, TSAC provided a 
safety recommendation to the Coast Guard, that towing vessel operators 
should ``close and dog watertight hatches during towing operations'' to 
minimize the risk of down-flooding and progressive flooding of the 
towing vessel.
    We have provided appropriate exceptions to the requirements in 
Sec.  140.610(c)(1)-(3) to give sufficient flexibility to the vessel's 
master for crew comfort and convenience. The Coast Guard has made no 
changes from the proposed rule based on these comments. However, in 
reviewing Sec.  140.610 on hatches and other openings, we added an 
express requirement, previously implied in that section, that decks and 
bulkheads designed to be watertight or weathertight must be maintained 
in that condition.
    Some commenters suggested that proposed Sec.  140.610(b) be revised 
as follows, ``The master must ensure that all hatches, doors, and other 
openings that were installed to be watertight and weathertight are 
functioning properly.''
    With one amendment, the Coast Guard agrees with the suggested 
revision. The intent of proposed Sec.  140.610(b) was that any fittings 
that crews rely on for watertight integrity and vessel safety should be 
operational and subject to survey. Our revision of Sec.  140.610(b) is 
intended to make two things clearer. First, this paragraph covers 
hatches, doors, and other openings designed to be watertight or 
weathertight, whether or not they are currently watertight or 
weathertight. Second, the reference to ``other openings'' in this 
section is also intended to be limited to those designed to be 
watertight or weathertight.
    One commenter recommended that proposed Sec.  140.615(a) apply to 
all towing vessels. Another company suggested that this section only 
apply to vessels that are not subject to 33 CFR 164.80 regulations.
    Because it would be redundant to apply Sec.  140.615 to towing 
vessels subject to 33 CFR 164.480, the Coast Guard agrees with the 
second commenter and has not made any changes to the applicability of 
Sec.  140.615 except that we replaced the term ``inspection'' with 
``examination'' to avoid using different terms to describe the same 
action.
    An individual suggested that repairs, such as repairs to navigation 
lights or whistles, need not be recorded as required in proposed Sec.  
140.620(d).
    The Coast Guard disagrees with the commenter's suggestion that the 
repairs to navigational safety equipment need not be recorded. The 
Coast Guard believes that a record of repairs made to navigational 
safety equipment is a vital component of good management and 
recordkeeping. Documentation of repairs made to such equipment is vital 
to identifying systemic issues affecting the navigational safety 
equipment.
    Additionally, if the vessel is operating in accordance with the 
safety management system, documentation of repairs made would serve to 
provide an account of materials needed and requested as well as 
corrective actions taken in order to address the observed deficiencies. 
The Coast Guard has made no changes from the proposed rule based on 
this comment.
    We received comments from a State government and a task force 
asserting that the Coast Guard should add language to Sec.  140.620 
requiring that vessels carrying oil or hazardous material in bulk 
immediately notify the COTP or OCMI when navigational safety equipment 
fails and cannot be immediately repaired.
    The Coast Guard does not agree with the commenters' suggestion that 
additional requirements for reporting are necessary in this rulemaking. 
In accordance with 33 CFR 164.53(a), a towing vessel may continue to 
the next port of call should navigation safety equipment fail, subject 
to the direction of the District Commander or the Captain of the Port 
as provided by 33 CFR part 160. A towing vessel is required by 33 CFR 
164.53(b) to report to the Coast Guard the loss of critical navigation 
safety equipment to include radar, radio navigation receivers, Gyro 
compass, echo-depth sounding devices, or primary steering gear. The 
Coast Guard believes that these existing requirements are sufficient to 
ensure safety for towing vessel operations, and we have made no changes 
from the proposed rule based on these comments. We inserted examples of 
navigation safety equipment in Sec.  140.620(c), but left the repair-
promptly requirements in that section clearly applicable to all 
navigation safety equipment.
    Similarly, after further review of Sec.  140.625, the Coast Guard 
decided not to repeat the list (of topics for special attention) 
already contained in 33 CFR 164.78; instead we refer to that CFR 
section in a note, and point to the TSMS, where such a list is more 
appropriately maintained.
    We received several comments, from maritime companies and 
individuals who felt that proposed Sec.  140.630 should be deleted from 
the NPRM. Several companies felt that because lookouts are included in 
Rule 5 of the Inland and International Navigation Rules (33 CFR 83.05), 
the section is redundant for subchapter M. Two commenters suggested 
that because lookouts for inspected crew boats are not required in

[[Page 40045]]

subchapter T, they should not be required in subchapter M. An 
individual asserted that the words ``dedicated'' or ``designated'' 
should be included before the word ``lookout'' to make it clear that a 
lookout position would be in addition to a watch-standing officer. A 
State government and task force member supported a second person for 
bridge watch for all towing vessel tank barges carrying oil or 
hazardous material in bulk.
    The Coast Guard does not agree that the requirements of proposed 
Sec.  140.630 should be altered or removed from the rule. The Coast 
Guard agrees that Rule 5 of the Navigation Rules clearly identifies the 
need to maintain a lookout at all times while underway. The Coast Guard 
believes that the additional language provided in Sec.  140.630 ensures 
that owners and managing operators of towing vessels have greater 
clarity on expectations and thresholds of performance for the placement 
of additional lookouts to maintain a state of vigilance whenever 
significant change in the operational environment occurs. This section 
makes clear that responsibility for navigational safety rests with the 
master and mate (pilot) of the towing vessel. Subchapter M establishes 
requirements for a class of vessels that have different operational 
risks than those covered by subchapter T. As for the requirement for a 
second person for bridge watch for all towing vessel tank barges 
carrying oil or hazardous material in bulk, the Coast Guard believes 
that Sec.  140.630 gives the Master the proper authority to establish 
an appropriate number of lookouts based on the conditions and other 
factors. To clarify the interaction of Rule 5 and 46 CFR 140.630, the 
Coast Guard has made changes from the proposed rule based on these 
comments.
    We received a comment suggesting that because navigation assessment 
is covered in other regulations, it should be eliminated from Sec.  
140.635. The commenter felt that because navigation watches are 
included in Navigation Rules 6, 7(a) and 8(a), it would be redundant to 
include them in subchapter M. Companies also stated that a navigation 
assessment should not be required in subchapter M because it is not 
required in subchapter T.
    The Coast Guard does not agree with the commenter's suggestion to 
remove Sec.  140.635. The requirements of Sec.  140.635 provide 
additional guidance and requirements for the vessel's master or mate 
(pilot) to ensure that the proper planning is conducted and that 
sufficient resources, personnel and equipment are available to mitigate 
the identified risks. In addition, subchapter M establishes 
requirements for a class of vessels that have different operational 
risks than those covered by subchapter T. The size of a towing vessel's 
tow may be large and continually changing, and more challenging to 
navigate than a small passenger vessel which has a consistent size. 
Also, varying heights of the tow--the tow's air draft--must be 
considered to determine if a tow is low enough to clear bridges along 
the towing vessels intended route. In contrast, the height of small 
passenger vessels normally remains constant. The Coast Guard has made 
no changes from the proposed rule based on this comment.
    Two commenters felt that a navigation assessment should be included 
in a company's TSMS and not included in the final rule. We received 
some comments that were in support of this provision. Three commenters 
suggested that navigation watch assessment language should be revised 
in accordance with the 2006 \4\ or 2008 \5\ TSAC recommendations on 
navigation watch assessments. An individual suggested that only vessels 
that transit in large areas should be required to have a navigation 
watch assessment. Two commenters felt that it was too burdensome to 
conduct and document a navigation assessment for each voyage the vessel 
makes in a watch.

Vessels, Sept. 7, 2006, docket ID no. USCG-2006-24412-0004.

Economic Analysis Working Group, Dec. 16, 2008, docket ID. No. USCG-

---------------------------------------------------------------------------

    The Coast Guard disagrees with the commenters' suggestion that the 
requirement for a navigation assessment should not be included as part 
of this rule but rather, be required in the company's TSMS. Not all 
companies or vessels are required to have a TSMS. Therefore, we have 
included these requirements here in part 140.
    The Coast Guard disagrees that the navigation assessment 
requirements will be overly burdensome. As noted by another commenter, 
the activities in the navigation assessment are required by Navigation 
Rules 6, 7(a) and 8(a), and the best practice of prudent seamanship. In 
the cases where the navigation assessment is not being fully 
implemented as current practice, we estimate that an additional 0.2 
hours per operating day of effort would be needed to meet the 
requirements in the final rule. We believe that subchapter M 
requirements for conducting navigation assessments prior to getting 
underway or while underway will ensure that officers in charge of the 
navigation watch have the most up-to-date information in order to 
assess operational risks as well as to anticipate and manage workload 
demands during the voyage.
    The Coast Guard believes that the requirements for the navigation 
assessment have taken into account the safety recommendations and other 
guidance received from TSAC. The TSAC recommendations were based on the 
premise that the details of the navigational assessment requirements 
would be contained in the TSMS. However, not all vessels will be under 
the TSMS scheme. Therefore we are separately including the navigation 
assesmment requirements here. The core elements of the recommendations, 
to identify risk and to take into account the unique characteristics of 
the tow, are included in this rule.
    Finally, the Coast Guard does not agree with the commenter's 
suggestion that only vessels that transit in ``large areas'' should be 
required to meet this requirement for navigational assessment. The term 
``large areas'' does not provide sufficient information to determine 
the boundaries envisioned by the commenter. Furthermore, navigation 
assessments have value not only for transits of large areas or of 
prolonged duration but also for transits in smaller areas or of short 
duration; shorter transits may also contain risks such as bridges, high 
winds, or swift currents. This requirement reflects good seamanship and 
best practices, and does not pose an undue burden to the mariner. The 
Coast Guard has made no changes from the proposed rule based on this 
comment.
    A State government and task force suggested that the Coast Guard 
require vessels towing tank barges that carry oil or hazardous material 
in bulk to develop a coastal and inland checklist to determine if 
weather conditions make it safe to proceed, and require personnel to 
complete the checklist before departure and retain it for Coast Guard 
inspection. These commenters also suggested we add language to proposed 
Sec.  140.625 to require a qualified licensed officer to be in charge 
of the navigation of the vessel, as stated in 33 CFR 164.11.
    The Coast Guard does not agree that additional language is required 
to address the commenters' concerns. Required tests, examinations, and 
assessments for personnel operating towing vessels are provided in 
Sec. Sec.  140.615 and 140.635. Section 140.635(a)(3) specifically 
requires that the person in charge of the navigation watch assess the 
``weather conditions and changes anticipated along the

[[Page 40046]]

intended route'' prior to getting underway. The Coast Guard believes 
that Sec.  140.635(a)(3) and other required considerations of the 
navigation assessment are sufficient to reduce operational risks and 
enhance the safety of the towing vessel and its tows.
    The Coast Guard notes that Sec.  140.625 clearly states that at all 
times, the movement of a towing vessel must be under the command of a 
credentialed mariner. The commenter correctly notes that existing 
regulations require a credentialed master or mate (pilot) to be in 
control of the vessel at all times while underway. The inclusion of 
additional language would not enhance the safety of towing vessel 
operations. The Coast Guard has made no changes from the proposed rule 
based on these comments.
    We received several comments from maritime companies that suggested 
that because other rules address the pilothouse requirements in 
proposed Sec.  140.640, it should be eliminated. Maritime companies and 
a trade association felt that the section should be deleted because 
sufficient coverage of this issue exists in Sec. Sec.  140.635 and 
140.645. Three commenters stated that because Sec.  140.640 is not 
required in subchapter T, it should not be required in subchapter M. 
However, three commenters supported this provision. Two commenters felt 
that Sec.  140.640 should incorporate the requirements in 33 CFR 164.80 
instead of the listed requirements.
    The Coast Guard does not agree with the commenters' suggestion that 
the requirements of Sec.  140.640 should be removed from this rule, or 
that navigation assessment requirements in Sec.  140.635, and Sec.  
140.645 navigation safety training requirements, satisfy the objective 
of requirements in Sec.  140.640 which are specific to pilothouse 
resource management. Towing vessels have significantly different 
performance capabilities from vessels regulated under subchapter T. As 
such, these vessels require greater levels of coordinated action and 
information transmission between members of the navigational watch 
team. The TSAC reports and AWO Bridge Allision study as well as 
casualty data all identify human factors as a causal factor in a large 
percentage of casualties. The Coast Guard believes that pilothouse 
resource management requirements will help reduce navigational risks. 
While we amended Sec.  140.640 for clarity, and as noted above in this 
discussion of part 140 comments to address distractions in Sec.  
140.210(d), the Coast Guard has made no changes from the proposed rule 
based on these comments.
    We intend this rule to provide--as much as practicable--the 
requirements for towing vessels in a single subchapter. Not all towing 
vessels are subject to 33 CFR part 164. For those that are, Sec. Sec.  
140.625 and 140.635 note the need for some vessels to comply with 
requirements in 33 CFR 164.78 or 164.80.
    We do view it as appropriate to tailor requirements in Sec.  
140.640 for those vessels subject to subchapter M rather than rely on 
existing requirements in 33 CFR 164.80. Also, we noted a tension 
between our statement in Sec.  140.600 that subpart F, Vessel 
Operational Safety, applies to all towing vessels unless otherwise 
specified, and our selective repeating of this statement in certain 
sections. To eliminate that tension, we deleted those unnecessary and 
somewhat confusing references to applicability in Sec. Sec.  140.625, 
140.635, and 140.640. Also, Sec.  140.600 noted that some vessels 
subject to subpart F remain subject to the navigation safety 
regulations in 33 CFR part 164. Sections 140.625, 140.635, and 140.640, 
as well as Sec.  140.725, contained statements about 33 CFR part 164 
applicability that we removed or moved to a note for the section 
because this was more informational than regulatory in nature. As 
discussed later in this preamble, however, we did delete Sec. Sec.  
140.810 and 140.815 and amended Sec.  140.800 to retain and clarify the 
statement about applicability.
    We received several comments from maritime companies who stated 
that because subchapter T does not require navigation training for 
deckhands, this training should not be required in Sec.  140.645. A 
professional association felt that obtaining a license is enough to 
qualify for navigation.
    The Coast Guard agrees in part with these comments. The Coast Guard 
recognizes that the training requirements in 46 CFR parts 11 and 12, 
for certain rating endorsements and all deck officer endorsements 
include the knowledge requirements listed in Sec.  140.645. We included 
a new paragraph (c) of this section to facilitate a link with the 
training requirements in 46 CFR parts 11 and 12.
    The Coast Guard, however, is also cognizant that not all mariners 
performing lookout functions are credentialed mariners therefore, we 
did not change the rest of Sec.  140.645. Lookout duties may be 
assigned to crew members aboard towing vessels who do not have a 
credential as master or mate. Additionally, a crew member may be 
assigned temporary duties to assist the navigational watch team in the 
pilothouse during underway operations. It is important that those crew 
members serving in such capacity have a basic understanding and 
elementary education in the skills necessary to perform any safety 
duties assigned to them aboard towing vessel.
    One commenter suggested that ``fuel'' also be included in the list 
of materials in Sec.  140.655(c) that should not be intentionally 
drained into bilges.
    The Coast Guard agrees that the drainage of fuel into the bilge 
poses a danger to the safety of towing vessel operations and the 
environment. Section 140.655(c) prohibits a person from intentionally 
draining oil or other hazardous material into the bilge of a towing 
vessel from any source. The Coast Guard intended the reference to ``oil 
or hazardous material'' in Sec.  140.655(c) to encompass ``fuel,'' but 
to make this clear we have added a sentence adopting 33 U.S.C. 1321's 
definition of ``oil'' which includes ``oil of any kind or in any form, 
including, but not limited to, petroleum, fuel oil, sludge, oil refuse, 
and oil mixed with wastes other than dredged spoil.'' With the adoption 
of this definition for purposes of Sec.  140.655, we deleted ``and 
fuel'' from Sec.  140.655(b) when referencing spills during transfers. 
To avoid any conflicting requirements, we amended Sec.  140.655(b)(2) 
regarding oil spill containment capacity to limit it to situations when 
the requirements in 33 CFR 155.320 do not apply.
    We received several comments about Sec.  140.655(c) from companies 
suggesting that because the prevention of oil and garbage pollution is 
already a requirement under other rules, such as 33 CFR 155.770, the 
Oil Pollution Act of 1990, and the International Convention for the 
Prevention of Pollution from Ships, this section should be deleted.
    The Coast Guard disagrees. By expressly stating the requirement in 
Sec.  140.655(c), we make clear that all vessels subject to subchapter 
M must comply with this requirement and the requirements stated in 33 
CFR 155.770. As previously mentioned, to the extent practicable, the 
Coast Guard is seeking to present in one subchapter nearly all the 
regulations with which a towing vessel subject to this rule must 
comply. This regulation prohibiting the intentional draining of oil or 
hazardous material into the bilge is one in particular that we want to 
ensure those subject to subchapter M are aware of. The Coast Guard has 
made no changes from the proposed rule based on these comments.
    A commenter stated that tests and inspections under provisions of 
National Fire Protection Association

[[Page 40047]]

(NFPA) 306, Control of Gas Hazards on Vessels, during repairs including 
welding, burning, or other hot work were easy to avoid on towing 
vessels because these vessels were not subject to Coast Guard 
inspection. Noting that the absence of prescriptive regulations 
restricts legitimate Coast Guard safety investigations to uncover the 
cause of accidents, the commenter recommended that the latest edition 
of NFPA 306, Control of Gas Hazards on Vessels, be incorporated by 
reference in this rule. Consistent with this recommendation, other 
commenters urged the Coast Guard to include a requirement for hot work 
operations and safety that is consistent with requirements for cargo 
vessels (46 CFR 91.50-1). This commenter also requested that the Coast 
Guard draft regulations for this rulemaking that govern the proper use 
of any autopilot installed on a towing vessel similar to those that 
apply to other classes of inspected vessels.
    The Coast Guard agrees that towing vessels should have requirements 
for hot work operations and safety, similar to cargo vessels, and that 
the standard recommended is appropriate and known within the maritime 
industry. In response to these comments, we added Sec.  140.665 which 
incorporates by reference portions of NFPA 306 in order to address 
Marine Chemist inspections required prior to making alterations, 
repairs, or other such operations involving riveting, welding, burning 
or like fire-producing actions.
    We also added Sec.  140.670 to address the use of auto pilot on 
towing vessels adopting regulations, as suggested. This regulation is 
similar to auto pilot regulations that apply to other classes of 
inspected vessels. We view these additions as needed to ensure the safe 
operation of towing vessels and as consistent with our proposal for a 
comprehensive subchapter M.
    We received several comments regarding proposed Sec.  140.725. 
Three maritime companies and a professional association felt that the 
requirement for a fathometer on vessels along the Gulf Intracoastal 
Waterway is not needed because the channel is ``static and marked,'' 
and because the depth of the water only changes by a couple feet. An 
individual stated that magnetic compasses should be allowed on the Gulf 
Intracoastal Waterway. Another commenter thought that ``electronic 
position fixing device'' was a vague term, and suggested either that it 
should be defined in Sec.  136.110 or that the definition in 33 CFR 
164.41 should be incorporated in Sec.  140.725(b)(3). This commenter 
also recommended that any devices installed 1 year after the effective 
date of the rule be required to be approved under series 165.130.
    The Coast Guard does not agree with the commenters' suggestion that 
a fathometer is an unnecessary piece of equipment aboard towing vessels 
operating in the Gulf Intracoastal Waterway. The Coast Guard agrees 
that towing vessels operating almost solely in marked channels 
regularly maintained and commonly traversed have a high degree of 
reliability with regard to water depth. However, these towing vessels 
sometimes deviate from marked channels. A fathometer is a very useful 
tool in order to ensure that a towing vessel does not run aground and 
is not damaged.
    The Coast Guard notes the commenter's suggestion that a magnetic 
compass should be allowed on the Gulf Intracoastal Waterway. There is 
nothing in this rule that prohibits the use of the magnetic compass on 
board a towing vessel when operating on the Gulf Intracoastal Waterway. 
In reviewing this comment, we amended Sec.  140.725 by inserting 
``illuminated'' before ``magnetic compass'' to match the illuminated 
requirement in that section for that alternative swing-meter, and to 
ensure the existing requirement that both must be readable is met.
    While there is no specific definition of ``electronic position 
fixing device'' found in 33 CFR 164.41, the term is generally now 
understood to mean a satellite navigation receiver, since that was 
allowed as a stand-alone means of satisfying the requirement in 1983 
(47 FR 58243, December 30, 1982) and the requirement was subsequently 
amended in 2011 once LORAN-based options were eliminated (76 FR 31831, 
June 2, 2011).
    The Coast Guard does not agree that 33 CFR 164.41 needs to be 
incorporated in the requirements of proposed Sec.  140.725(b)(3), but 
we have added a definition of ``electronic position fixing device'' in 
Sec.  136.110 that defines the term to mean a navigation receiver that 
meets the requirements of 33 CFR 164.41. Also, we view the 
recommendation for approval under series 165.130 as being overly 
prescriptive to include in this final rule without first seeking 
comments on that specific proposal.
    Note that we reorganized Sec.  140.725 for greater clarity. We 
decided that paragraph (a) was unnecessary so we removed it, and we 
made proposed paragraph (b) into introductory text, and paragraphs 
(b)(1) through (4) became paragraphs (a) through (d).
    One commenter suggested that the guidance in CG-543 Policy Letter 
10-05 regarding carrying electronic navigation publications on U.S. 
vessels should be adopted in subchapter M.
    The Coast Guard declines to specifically add this language into the 
final rule; however, on February 3, 2016, CG-NAV published NVIC 01-16, 
which esblishes guidance on the use of electronic charting systems and 
the carriage of electronic navigation pubs. NVIC 01-16 applies to 
towing vessels and their requirement for the carriage of navigation 
publications listed in Sec.  140.705. In examining our reference to 
``information and equipment'' in Sec.  140.705(b), we replaced these 
words with ``charts, maps, and nautical publications,'' to better 
reflect the section heading and the existing references in the section.
    Another commenter suggested that a note should be included in Sec.  
140.705(b)(1) that in the event that only electronic charts are used, 
the system must be approved by the Coast Guard.
    The Coast Guard does not agree. Section 140.705 already requires 
that if electronic charts are used, that they must be acceptable to the 
Coast Guard. This allows the Coast Guard to consider the system on 
which the charts will be displayed when determining if the charts will 
make safe navigation possible. The broader issue of electronic chart 
systems would be addressed in a separate rulemaking. The Coast Guard 
has made no changes from the proposed rule based on this comment.
    One commenter suggested that the final rule should require that 
officers on watch listen to the Coast Guard Broadcast Notices to 
Mariners (BNM) and National Weather Service regularly to avoid hazards. 
The commenter also suggested that ``talk-back'' capabilities be 
available for crew members that are out of sight of the watch officer.
    The Coast Guard does not agree with the commenter's suggestion to 
require navigational officers on watch to maintain the suggested radio 
watch aboard the towing vessel. Existing 33 CFR part 26 regulations 
address radio watch standing requirements. Moreover, whenever a vessel 
is operating in a Vessel Traffic Service Area, 33 CFR part 161 provides 
additional requirements for a towing vessel to maintain a radio watch.
    Also, the Coast Guard does not agree with the commenter's 
suggestion that a ``talk-back'' requirement be made applicable for crew 
members that are out of sight of the watch officer. The requirements 
contained in Sec.  140.640 on pilothouse resource management address 
information sharing procedures. Further, if the condition of the vessel 
or the construction of the vessel prohibits

[[Page 40048]]

direct communication between the members of the navigation watch team, 
then it is the responsibility of the vessel owner or managing operator 
to provide the necessary equipment to ensure that communication is 
conducted in a manner that provides for safer operation of the vessel. 
The Coast Guard has made no change from the proposed rule based on 
these comments.
    With respect to Sec.  140.715, one commenter suggested that at 
least two Very High Frequency (VHF) radios capable of Digital Selective 
Calling be maintained on board and also that towing vessels operating 
outside of the VHF range have long-band medium frequency or high 
frequency radio equipment or a satellite system. Further, the commenter 
recommended that all towing vessels should be capable of receiving 
Maritime Safety Information Broadcasts. The commenter warned against 
provisions allowing cellular radios as an alternative means of required 
communication function. The commenter also suggested that changes to 
equipment be required immediately following a first inspection or no 
later than 5 years from the effective date of the regulations.
    The Coast Guard does not agree with the commenter's suggestion. 
Section 140.715 reflects a performance standard from current 
regulations. As required by 33 CFR 164.72, as long as a continuous 
listening watch is maintained, the vessel is in compliance. It is the 
responsibility of the master to meet this performance standard. These 
requirements are identical to those contained 33 CFR 164.72 and 33 CFR 
part 26. The Coast Guard has made no change from the proposed rule 
based on this comment.
    We received several comments from companies and individuals 
regarding towing safety in subpart H of part 140. One commenter 
suggested deleting the responsibilities listed in paragraphs (a) 
through (c) in proposed Sec.  140.801 and replacing them with language 
from 33 CFR 164.74.
    The Coast Guard does not agree with the commenter's suggestion 
because 33 CFR 164.74 only addresses towing astern. The Coast Guard has 
made no changes from the proposed rule based on this comment. However, 
we have added ``or officer in charge of a navigational watch'' to the 
list of parties who may be responsible for meeting the requirements of 
this section, for greater consistency with similar requirements 
elsewhere. See discussion of Sec.  140.210 above for more.
    With regard to towing vessel horsepower two commenters expressed 
concern that the determination of horsepower or bollard pull of the 
vessel in Sec. Sec.  140.801 and 140.805 needed to safely maneuver the 
tow would be subjectively determined by the owner or managing operator 
of the vessel. One commenter felt that companies were not determining 
horsepower or bollard pull accurately, and suggested that the Coast 
Guard require that companies provide a document from the engine 
manufacturer and certified naval architect that rates the vessel's 
horsepower using data provided by the maker, the vessel's gear 
reductions ratio, and the diameter and pitch of the vessel's propeller.
    The Coast Guard does not concur. We included a definition of 
``horsepower'' in the definitions section of part 136, and we see no 
compelling reason to require additional testing that would not be 
appropriate for all towing vessels. The definition of horsepower 
requires that the determination of a vessel's horsepower is made by the 
Coast Guard or a third-party organization during the issuance of the 
COI, and is made using objective information issued by the 
manufacturer. The Coast Guard feels that the concerns regarding the 
determination of adequate horsepower are addressed in other sections of 
part 140 and are appropriately left to the master's assessment to the 
specific aspects of the tow, towing vessel's capability, and the 
prevailing conditions.
    The Coast Guard has made no changes from the proposed rule based on 
these comments.
    One commenter suggested that a reference to guidelines from the AWO 
RCP be included in Sec.  140.801 because the current language of the 
section left too much discretion to the owners and managing operators 
of towing vessels. One company suggested edits to Sec.  140.801 that 
would have rendered it inapplicable to excepted vessels, harbor assist 
vessels, vessels operating in a limited geographic area, or vessels 
operating on short hauls.
    The Coast Guard does not agree with the commenter's suggestion 
concerning the inclusion of a reference to the AWO RCP. Section 140.801 
requires that the owner, managing operator, or master of a towing 
vessel ensures compliance with the performance standards in Sec.  
140.801. Those with this responsibility may rely on a TSMS, guidance 
documents, or other sources in deciding how best to meet these 
requirements.
    Also, the Coast Guard does not agree with the commenter's 
suggestion of altering the applicability of Sec.  140.801. The towing 
gear in Sec.  140.801 is just as important for those vessels the 
commenter listed as for other vessels subject to subchapter M. The 
Coast Guard has made no changes from the proposed rule based on these 
comments.
    We received several comments from companies and a trade association 
that suggested the deletion of proposed Sec. Sec.  140.815 and 140.820 
concerning the inspection of towing gear and related recordkeeping. The 
comments suggested replacing these sections with requirements from 33 
CFR 164.74 and towline and terminal gear requirements from 33 CFR 
164.76. Commenters felt that this change will help reduce confusion 
between the towing safety regulations and these subparts. Another 
commenter suggested that we add text to proposed Sec.  140.820 to 
augment the recordkeeping requirements.
    The Coast Guard agrees with the first commenter's recommendations. 
We have deleted Sec.  140.810 because Sec.  140.615 will require that 
towing gear be examined before getting underway for all towing vessels 
not subject to 33 CFR 164.80 already, and we deleted Sec.  140.815 
because it was merely informational. We also amended Sec.  140.820 to 
apply the recordkeeping to the inspections in 33 CFR 164.76 instead of 
Sec.  140.815 as previously proposed.
    The Coast Guard also agrees with the second comment, and we have 
adopted an amended version of the commenter's proposed change to Sec.  
140.820(b). We edited Sec.  140.820 to remove ``bridle'' from the 
recordkeeping requirements for examination, because bridles are 
normally either attached to or are part of the barge and it would be 
too onerous for industry to complete this recordkeeping requirement on 
towing gear not under the continuous control of the towing vessel.
    One commenter suggested that the description of TSMS recordkeeping 
should include the acceptance of electronic recordkeeping as an 
alternative. Also, a commenter discussing the official log book 
mentioned the possibility of making false or late entries. A third 
commenter supported the TSMS and requested that a towing vessel record 
as defined in Sec.  136.110 be the exclusive form of recordkeeping for 
all records cited in Sec. Sec.  137.135, 137.210, and 138.215.
    As stated in 46 CFR 140.910(c), TVRs may be maintained 
electronically or on paper. For towing vessels with a TSMS, however, 
Sec.  140.910(b) states that another record--other than the TVR, as 
provided by the TSMS, must be maintained. We agree that this TSMS 
record may also be in electronic or paper form. But to discourage false 
electronic entries, we have amended Sec.  140.915(b) to add specific 
entry requirements for electronic records to

[[Page 40049]]

include the date and time of entry and name of the person making the 
entry. If an error is discovered in an entry, any entries to correct 
the error must include the date and time of entry and name of the 
person making the correction and must preserve a record of the original 
entry being corrected.
    With regard to making false or late entries, we note that under 18 
U.S.C. 1001, whoever knowingly and willfully makes a materially false, 
fictitious, or fraudulent statement or representation with respect to 
reports, records, or verifications required by subchapter M 
regulations, may be subject to criminal penalties.
    Regarding the third comment, the Coast Guard recognizes that a 
towing vessel owner or managing operator is required to compile records 
and reports in multiple formats and in separate logs and ledgers. Each 
of these records have relevance to the TSMS aboard a vessel and are a 
resource for the auditor and the surveyor to review in order to 
determine proof of adherence to the requirements of the Safety 
Management System. The Coast Guard does not wish to impose a regulatory 
requirement that would result in unnecessary recordkeeping requirements 
upon industry. Requiring all of these records to be kept in one central 
record system for the purposes of this rulemaking would be impractical. 
The owner or managing operator of the towing vessel has the latitude to 
tailor their Safety Management System to define the method and location 
of those records central to the safe operation, repair and maintenance 
of the towing vessel. We have not made changes from the proposed rule 
based on these comments.
    Two commenters felt that the proposed recordkeeping requirements in 
Sec. Sec.  140.905 and 140.910 are not consistent with the 46 U.S.C. 
11304.
    The Coast Guard acknowledges that while the 2010 Act was enacted in 
October 2010, its requirement for an official logbook in 46 U.S.C. 
11304 was not addressed in our proposed rule. We are not, however, 
amending Sec.  140.905 or Sec.  140.910 in this final rule. We will 
consider addressing 46 U.S.C. 11304 requirements in a separate 
rulemaking that would apply to all vessels subject to inspection, and 
not just those subject to subchapter M. Further, because 46 U.S.C. 
11304 makes reference to hours of service, we would again need to 
consider a separate rulemaking as we would want to seek comments on a 
specific proposal before implementing those requirements for towing 
vessels. We have made no changes from proposed Sec.  140.905 or Sec.  
140.910 based on these comments.
    One commenter expressed concern regarding potential inconsistencies 
between the unofficial and official Coast Guard logbook forms. The 
commenter suggested that vessels operating on the Great Lakes should be 
exempt from the requirement to maintain an official logbook under Sec.  
140.905.
    The Coast Guard disagrees with changing Sec.  140.905 to exempt 
vessels operating on the Great Lakes. The requirement to maintain an 
official log comes from 46 U.S.C. 11301, and Sec.  140.905(a) reflects 
the language of the statute, including the exception for vessels on a 
voyage from a port in the United States to a port in Canada. We did 
make minor changes to this subpart: In Sec.  140.910(d), we corrected a 
logbook reference that should have pointed to Sec.  140.905, and in 
Sec.  140.915 we added a note observing that for towing vessels subject 
to 46 U.S.C. 11301, there are additional logbook requirements in 
statute, and that Sec.  140.915 does not alter requirements outside 
subchapter M to make entries in specific log books.
    One commenter suggested that language from SOLAS V, regulation 28, 
Records of navigational activities, be considered in place of the first 
sentence of TVR requirements in proposed Sec.  140.910(c). The revision 
would have replaced proposed language about a chronological record of 
events with language about activities and incidents of importance to 
safety of navigation of the vessel, sufficient to restore a complete 
record of the voyage.
    The Coast Guard disagrees. The requirements of SOLAS V are designed 
to meet the needs of an international seagoing community and provide 
for much greater depth and comprehensive guidance than that of Sec.  
140.910(c). Additionally, the requirements of Sec.  140.910(c) have 
been tailored for use by the domestic towing fleet and provide a 
reduced burden upon vessel owners and operators. In proposed Sec.  
140.915, however, we have added a reference to tests and examinations 
that are required by Sec.  140.615. We believe the commenter's concern 
is addressed by reading Sec.  140.910(c) in combination with the 
specific reporting requirements of Sec.  140.915, as amended.
    We received two comments from towing companies who felt that 
compliance with subpart I of part 140 would be time consuming and a 
burden on companies and the Coast Guard.
    The Coast Guard acknowledges the documentation requirements of this 
portion of the rule do require some time and familiarity on the part of 
the crew. However, we believe the documentation will result in a higher 
level of operational safety and effectiveness, which improves 
operational performance. The time invested in complying with the 
recordkeeping requirements of this portion of the rule is intended to 
provide sufficient benefits to offset the time invested. The Coast 
Guard has made no changes from the proposed rule based on these 
comments.
    Two companies requested that the definition of ``towing vessel 
record or TVR'' as stated in Sec.  136.110 be a substitute for the 
official logbook, CG-706B or CG-706C, required in Sec.  140.905.
    The Coast Guard disagrees. Our definition of ``towing vessel record 
or TVR'' allows that record to take a variety of forms, ``a book, 
notebook, or electronic record.'' In Sec.  140.905 of this rule we 
identify vessels that are required under 46 U.S.C. 11301 to use the 
official logbook, and in Sec.  140.905(b) we specify the form of the 
official logbook. We did not propose to alter the form of the official 
logbook in the NPRM, nor do we wish to do so in this final rule. The 
official logbook is standardized for all vessels required by statute to 
have it. The Coast Guard has made no changes from the proposed rule 
based on these comments.
    We received several comments from maritime companies, an 
individual, and a professional association suggesting that the language 
in Sec.  140.915 be clarified to state that the items must be recorded 
in accordance with the TSMS associated with the vessel and not recorded 
in the TSMS itself. The Coast Guard agrees, and amended Sec.  140.915 
to reflect this suggested change.
    One commenter asserted that the language in proposed Sec.  
140.1005, Suspension and revocation, is too broad and potentially could 
lead to ``outright abuse,'' in the commenter's words, of mariners for 
mistakes made without criminal intent. A towing company suggested the 
deletion of Sec.  140.1005 because it is addressed in 46 U.S.C. 7703.
    The Coast Guard disagrees. We believe it is appropriate and helpful 
to identify penalties that those holding a license, certificate of 
register, or merchant mariner credential may be subject to. Our 
language in Sec.  140.1005 is similar, for example, to language in 46 
CFR 185.910 in subchapter T. In reviewing Sec.  140.1005(b) in response 
to this comment, we added a source reference of 46 U.S.C. 7704 in the 
introductory text of Sec.  140.1005, and paragraph (d) to include a 
security risk element listed in 46 U.S.C. 7703.
    One commenter argued that the marine industry must understand that 
the Coast Guard will take equal action against both mariners and 
companies for

[[Page 40050]]

violations of regulations in subchapter M.
    The Coast Guard has a broad range of options to enforce regulations 
against mariners, companies, or both. The OCMI will conduct an 
investigation and make determinations as to appropriate course of 
action, which may include civil penalties or criminal actions. The 
Coast Guard has made no changes from the proposed rule based on this 
comment.
    Lastly, a towing company pointed out that the regulations are 
currently written to assume a male captain and suggested that revisions 
should be made throughout the regulations to replace gender-specific 
text with him or her, or his or her.
    The Coast Guard agrees. We have amended the text in the final rule 
to ensure we consistently use gender-neutral language throughout the 
rule.

K. Lifesaving (Part 141)

    We received several comments from maritime companies, individuals, 
and an association regarding lifesaving requirements in part 141. 
Several comments revealed misinterpretations of the proposed rule, so 
we have made editorial revisions throughout this part, including some 
rearranging, restructuring, and renumbering of the text, to improve 
clarity and readability.
    Three maritime companies recommended deleting or revising part 141 
because of lack of demonstrable risk justifying additional costs to 
regulated entities.
    The Coast Guard analyzed the casualty data balanced against the 
costs associated with implementing this rule. The details of this 
analysis can be found below in the Regulatory Analysis section of this 
final rule. As is discussed in more detail there, we found that the 
benefit of risk reduction was commensurate to the cost or, in some 
cases, we revised the rule to avoid costs that exceeded the benefit. 
For the lifesaving requirements in part 141, the Coast Guard estimates 
the annualized cost to be $3.2 million, with annualized benefits of 
$4.4 million, resulting in a net benefit of $1.2 million per year. The 
positive net benefits estimate indicates that the potential risk 
reduction justifies the additional cost of the part.
    The carriage, operation, and maintenance of certain approved 
lifesaving equipment is a fundamental aspect of being an inspected 
vessel. The Coast Guard analyzed the costs associated with implementing 
lifesaving provisions of this rule and concluded that the largest costs 
associated with the proposed rule arise from the carriage of survival 
craft, particularly for inland towing vessels. Noting that the 
operating conditions may mitigate the need for survival craft, the 
Coast Guard has modified the proposed requirements for survival craft 
as described below to reduce the impact on the towing vessel industry. 
The Coast Guard believes that provisions of this final rule represent 
the minimum requirement for safe operation of an inspected towing 
vessel and notes that nothing in this rule would preclude a towing 
vessel operator from optionally carrying survival craft as excess 
equipment.
    In a comment on part 141, a commenter suggested that all our 
references to limited geographical areas should be expanded to include 
vessels operating in harbor services.
    In part 141 we proposed that, unless required by the OCMI under 
Sec.  141.305(c)(5), a towing vessel in a limited geographic area need 
not carry a survival craft. In this final rule, that provision is 
reflected in the first area-of-operation column in Table 141.305 of 
Sec.  141.305 and in footnote 1 of that table. Our definition of 
``limited geographic areas'' in Sec.  136.110 gives the COTP the 
discretion to determine limited geographic areas in her or his COTP 
zone. We don't see a need to change that definition based on this 
comment, which seems more focused on ensuring that vessels engaged in 
harbor services share the same exceptions as those operating in a 
limited geographic area. A vessel that engages in harbor services may 
do so in multiple locations and may not always be operating in a 
limited geographic area, and is not necessarily exempted from carrying 
survival craft. A vessel that engages in harbor services within a 
limited geographic area as determined by the COTP, however, need not 
carry survival craft unless required to do so by the OCMI.
    In response to general comments about having time to comply with 
equipment-related requirements in subchapter M, we amended Sec.  
141.105 to give existing towing vessels until the earlier of either 2 
years from the effective date of this rule or the date the vessel 
obtains a subchapter M COI to comply with part 141 requirements. We 
added Sec.  141.105(a)(2) to clarify that the delayed implementation 
provisions for existing vessels do not apply to new towing vessels. We 
also revised Sec.  141.105(c) to include a reference to SOLAS Chapter 
III as this is where specific lifesaving requirements are contained in 
SOLAS.
    Because the reference to functional requirements in proposed Sec.  
141.110 only applies to survival craft, we relocated that text to Sec.  
141.305. An individual suggested we edit proposed Sec.  141.110 (now 
Sec.  141.305) by adding ``company'' to those we identified (``owner or 
managing operator'') who may choose to meet the functional requirements 
in this part instead of the part's prescriptive standards.
    We do not agree. We do not see a need to do so because our Sec.  
136.110 definition of ``managing operator'' includes organizations and 
if a company owns the vessel, it would be covered by our definition of 
``owner.''
    The same commenter also suggested that the designated approved 
third party provide written recommendations to the cognizant OCMI 
regarding the OCMI's acceptance of functional requirements, instead of 
the third party directly accepting them.
    We do not agree. A TPO may consult with the OCMI, but under 
proposed Sec.  141.110(c) (now Sec.  141.305(c)(2)) the TPO is free to 
accept a managing operator or owner's chosen means to meet the survival 
craft requirements of Sec.  141.305, so long as the means are 
documented in the TSMS applicable to the vessel. We believe these 
documentation procedures are sufficient and do not see a need for the 
TPO to provide written recommendations to the cognizant OCMI regarding 
acceptance of arrangements that satisfy the functional requirements.
    We did not receive comments on Sec.  141.115, Definitions, but 
noted that no new definitions were proposed for this part, and removed 
this section. Additionally, as discussed elsewhere in this preamble, in 
response to requests for clarification on the appropriate approvals for 
lifesaving equipment, we imported the definition of ``approval series'' 
from 46 CFR 199.30 to the definition section for subchapter M and used 
that term in part 141 to identify the applicable approval series for 
each piece of equipment
    We did not receive comments on the incorporation by reference 
section, Sec.  141.120, but we did move the contents of that section 
into Sec.  136.112 and made Sec.  136.112 the centralized incorporation 
by reference section for all of subchapter M. In addition, to better 
organize the various technical standards used throughout subchapter M, 
we also consolidate central incorporation by reference sections for 
other parts into Sec.  136.112.
    An individual recommended that in Sec.  141.205(a) we add 
``guidelines, instructions, and define level of authority'' to what the 
TSMS must include in addition to policies and procedures. The same 
commenter also recommended that in paragraph (b) of that section we 
require the TSMS to

[[Page 40051]]

``include procedures ensuring that non-conformities, accidents and 
hazardous situations are reported to the company, owner, or managing 
operator, investigated and analyzed with the objective of improving 
safety and pollution prevention,'' instead of simply ensuring objective 
evidence of compliance with the TSMS.
    The Coast Guard disagrees. We have deleted Sec.  141.205 entirely 
because we felt that it was redundant with part 138 in general. As for 
the commenter's concern, Sec.  138.220, Towing Safety Management System 
(TSMS) Elements, requires that the TSMS include documentation of the 
management organization in detail, personnel management policies, and 
compliance with other requirements of this subchapter.
    We did not receive comments on the general provisions section for 
part 141, proposed Sec.  141.220 (now Sec.  141.200), but the Coast 
Guard standardized our approval phraseology both here and throughout 
this subchapter and also clarified the specific approval required for 
each equipment type. These edits are consistent with requests discussed 
below regarding Sec.  141.305 to clarify the appropriate approvals for 
lifesaving equipment. At the time of their inspection, every towing 
vessel must be properly outfitted in accordance with the route for 
which they are certificated. However, we further clarified in new Sec.  
141.200(c) that requirements in part 141 are based solely on the areas 
where a vessel operates.
    We did not receive comments on Sec.  141.225, but we found that the 
provisions of Sec.  136.115 were more applicable to this part and cited 
this section in new Sec.  141.225(a) to reflect Sec.  136.115's 
provision that all towing vessels, not just those with a TSMS, may seek 
equivalencies. Similarly, we redesignated Sec.  136.115(c) as Sec.  
141.225(c) to better align the provisions concerning equivalencies of 
novel lifesaving appliances or arrangements within part 141. In 
addition, we restructured 141.225 by replacing proposed paragraph (a) 
with new paragraphs (a) and (b) to clarify the intent allowing towing 
vessels to use alternate arrangements or equipment to meet this part. 
We also amended the heading of Sec.  141.225 to better reflect this 
section's paragraph (d), which specifies that the cognizant OCMI may 
require a towing vessel to carry specialized or additional lifesaving 
equipment.
    An individual recommended text edits to Sec.  141.230 that would 
require the master to ensure that lifesaving equipment is correctly 
installed in addition to being properly maintained and ready for use at 
all times.
    The Coast Guard does not agree. To the extent improperly installed 
lifesaving equipment would not be ready for use, the wording of Sec.  
141.230 addresses the commenter's concern. We made no changes in 
response to this comment.
    Regarding Sec.  141.235 and the inspection, testing, and 
maintenance of lifesaving equipment, we received a comment from an 
association suggesting that the content of 46 CFR 199.190, which we 
reference in Sec.  141.235, be added as a stand-alone section in 
subchapter M with modifications to apply to towing vessel lifesaving 
equipment and to clearly specify when any necessary factory maintenance 
is required.
    The Coast Guard does not agree. The full text of Sec.  199.190 
contains maintenance requirements for various types of lifesaving 
equipment, including weekly, monthly, and annual inspections and tests 
for lifeboats, rescue boats, and launching appliances. The majority of 
towing vessels will not carry this equipment. Therefore, the inclusion 
of the complete text of Sec.  199.190 in subchapter M would add little 
value. However, Sec.  141.235 points the operator to Sec.  199.190 
where he or she can search for the relevant testing and maintenance 
requirements for vessels that carry this equipment. In Sec.  141.235, 
we replaced the word ``examination'' with ``inspection'' to be 
consistent with other related Coast Guard regulations. Also, seeking 
consistency with a similar provision in Sec.  142.240, we set the 
records retention period to at least 1 year after the expiration of the 
Certificate of Inspection.
    We received several comments regarding Table 141.305--Survival 
Craft. One commenter requested that all towing vessels be equipped with 
an out-of-water survival craft, like an inflatable buoyant apparatus. 
An individual felt that life floats and buoyant apparatus references 
should be deleted from the table, with the exception of references in 
footnotes. A trade association and individual noted two terms that 
should be changed; ``life floats'' because it was ordered removed by 
Congress by January 1, 2015, and the term ``buoyant apparatus,'' which 
was suggested to be replaced with ``approved buoyant apparatus'' in 
order to comply with proposed Sec.  141.305(c)(6). Another commenter 
suggested that we edit proposed Sec.  141.305(b)(6) and (c)(6) by 
replacing ``By 2015,'' with ``After December 31, 2014,'' when 
specifying when survival craft may no longer be carried on board unless 
the craft ensures that no part of the individual is immersed in water.
    On February 8, 2016, section 301 of the Coast Guard Authorization 
Act of 2015 (2015 Act), Public Law 114-120, 130 Stat. 27, revised 46 
U.S.C. 3104. The deadline in our proposed Sec.  141.305(b)(6) and 
(c)(6), and Sec.  141.330(g), for a new standard for survival craft to 
meet to be eligible for approval--``must ensure that no part of an 
individual is immersed in water''--was based on provisions previously 
specified in 46 U.S.C. 3104. The 2015 Act limited those standards for 
survival craft to passenger vessels. We have therefore removed 
references to the deadline and those standards in Sec.  141.305(b) and 
(c), and Sec.  141.330, and made edits to align the language with the 
remaining functional requirements for survival craft.
    We developed the cost estimates for part 141 under the requirements 
of 46 U.S.C. 3104 before it was amended by the 2015 Act. Specifically, 
we posited that owners and operators of the affected vessel population 
would only use inflatable buoyant apparatuses to comply with the out-
of-water mandate. To the extent that affected owners and operators take 
advantage of the relaxation of equipment requirements provided by the 
2015 Act, this will result in an over-estimate of the cost of survival 
craft in this rule's regulatory analysis.
    As recommended, we deleted the terms ``buoyant apparatus'' and 
``life float'' from the Cold Water Operation portion of Table 141.305 
because neither of these items satisfied the minimum requirements for a 
vessel operating in cold water. In the Warm Water Operation portion of 
the table we removed the rows for life float and inflatable buoyant 
apparatus because they are not specifically called out to meet the 
minimum carriage requirements although they can be used as a substitute 
for a lower safety precedence survival craft as described in Sec.  
141.305(d). To avoid possible confusion with ``inflatable buoyant 
apparatus,'' we changed ``buoyant apparatus'' to ``rigid buoyant 
apparatus'' throughout the final rule. Also, to accurately reflect the 
safety precedence hierarchy of survival craft, we moved Inflatable 
Liferaft with SOLAS A pack to the bottom of each list.
    Also, we have revised the requirements for carriage of survival 
craft to exclude vessels operating in protected waters, which we have 
defined in Sec.  136.110, unless survival craft are deemed necessary by 
the OCMI, and we have revised Sec.  141.305(d) to allow for non-
approved survival craft

[[Page 40052]]

to be carried as excess equipment where no survival craft are required 
by this part, provided that the equipment is in good condition and 
maintained according to manufacturer's instructions.
    In order to further clarify the options for complying with the 
functional requirements for survival craft, we have added a new 
paragraph to Sec.  141.305, which includes text relocated from proposed 
Sec.  141.110. Under the new Sec.  141.305(c), the two options for 
complying with the functional requirements for survival craft are 
meeting the prescriptive requirements in Sec.  141.305(d) or employing 
alternative means, acceptable to the OCMI or TPO, and documented in the 
TSMS, if applicable.
    A towing company suggested that the table include ``Rivers and 
Canals'' as an area of operation.
    The Coast Guard does not see a need for this suggested change. 
Table 141.305 currently lists ``Rivers'' as an area of operation and 
the definition of ``rivers'' in Sec.  136.110 includes canals.
    Another commenter suggested removing all rows from the table where 
equipment is not required. The same commenter suggested that operations 
that are exempt from specific equipment requirements be indicated by 
the word ``none'' in the appropriate field in the table. The Coast 
Guard agrees, and has revised Table 141.305 accordingly.
    We received several comments regarding the footnotes in Table 
141.305. Several commenters, including towing companies and 
associations, suggested deleting proposed footnote 1 that referenced 
survival craft determinations by the cognizant OCMI or as a requirement 
deemed necessary in the applicable TSMS. Alternatively, an individual 
suggested that a towing vessel operating in ``limited geographic 
areas'' be permitted to operate without survival craft.
    According to footnote 1 of Table 141.305 in the final rule, 
survival craft are not required on towing vessels operating in limited 
geographical areas, ``unless survival craft requirements are determined 
to be necessary by the cognizant OCMI or TSMS applicable to the towing 
vessel.'' Though the Coast Guard does not support requiring survival 
craft on towing vessels operating in limited geographic areas, unless 
the OCMI or TSMS deems them necessary under Sec.  141.225, operators of 
these vessels are welcome to carry properly maintained survival craft 
as excess equipment. A towing company recommended that towing vessels 
operating within 1 mile of the shore should not be required to have 
survival craft, unless determined necessary or if it is required in the 
TSMS for that particular towing vessel. A maritime company suggested 
deleting the text, ``unless determined to be necessary by the cognizant 
OCMI or a TSMS applicable to the towing vessel,'' from proposed 
footnote 6, but didn't provide any reasoning for this suggestion.
    The Coast Guard does not agree with the proposed amendment to 
footnote 6. We believe this provision in proposed footnote 6 is 
appropriate because the OCMI (or author of the TSMS) should be able to 
evaluate any extenuating circumstances associated with the towing 
vessel's operation that would require a survival craft when in general 
they are not needed when the towing vessel is operating within 1 mile 
of shore. As noted below, however, based on another comment we did move 
the text of this footnote to Sec.  141.305(d)(3)(iii).
    Several commenters suggested that footnotes 5 and 6 in the table be 
moved into the regulatory text, and one commenter recommended deleting 
the reference to OCMI approval when moving the text of footnote 6.
    We agree that the content of proposed footnotes 5 and 6, as well as 
footnote 4, should be moved into paragraph form in the regulatory text 
to aid the reader. Therefore, we have inserted the provisions of these 
footnotes into paragraphs (d)(3)(i)-(iii) of Sec.  141.305. We 
disagree, however, with deleting the reference to an OCMI 
determination. When moving the content of proposed footnote 6, we did 
insert the source of the OCMI's authority to make such a determination.
    One company suggested that because of fast currents in some 
waterways, life floats should be permitted to be retained as 
supplemental approved survival craft for limited applications as 
approved by the Coast Guard. Because of downriver flow, the time that 
the crew is in the water, and the time for life raft deployment, the 
commenter states it would be difficult for crew to swim against the 
Lower Mississippi River's current to catch the life raft that released 
and inflated a period of time after the crew member went into the water 
as would happen with an automatic deployment. This commenter notes that 
crew members in the water would have a much better chance of reaching a 
life float as they and it are swept downriver with the current at the 
same relative speed.
    The Coast Guard acknowledges the commenter's concerns, and in Sec.  
141.305(d)(2)(iv) we have permitted a life float approved under 
approval series 160.027 to be substituted for a rigid buoyant 
apparatus. Also, proposed Sec.  141.220 would have required lifesaving 
equipment to be of an approved type, unless otherwise specified. We 
amended that section, now Sec.  141.200, to specify that lifesaving 
equipment for personal use need not be approved by the Commandant if it 
is not required by part 141. We also amended Sec.  141.305(d) to allow 
the carriage of non-approved survival craft as excess equipment, 
provided that the equipment is maintained in good working condition 
according to the manufacturer's instructions.
    We edited Sec. Sec.  141.310 and 141.315 to make it clear that they 
are applicable to vessels that do not have an applicable TSMS.
    As noted in our discussion of comments on Sec.  141.305, the Coast 
Guard does not agree with the assumption that the vessel and its tow 
operating more than 1 mile from shore could make it to shore in the 
event of an accident. Section 141.330 does not impose a separate 
requirement that ``other survival craft'' be carried: Instead it simply 
sets out the requirements for a skiff if the skiff is intended to be 
used as a substitute for approved survival craft required by Table 
141.305. Table 141.305 prescribes the operating areas where an approved 
inflatable liferaft is required. As noted above, the Coast Guard has 
included additional text in Sec.  141.305 prescribing the hierarchy of 
approved survival craft, and giving owners and operators the right to 
substitute a survival craft of higher precedence. For example, Sec.  
141.305(d)(3)(ii) allows an inflatable liferaft approved under approval 
series 160.051 or 160.151 to be substituted for an inflatable buoyant 
apparatus or rigid buoyant apparatus. Similarly, an inflatable buoyant 
apparatus approved under approval series 160.010 or life float under 
approval series 160.027 may be substituted for a rigid buoyant 
apparatus (Sec.  141.305(d)(3)(iii) and (iv), respectively). If the 
operator would prefer to use a non-approved raft as a survival craft, 
the functional requirements listed in Sec.  141.305(b) would apply to 
the raft.
    We received several comments concerning the use of skiffs. One 
individual noted that the proposed rule contained no requirement that a 
skiff comply with any requirements for safe loading or buoyancy. The 
commenter recommended that we amend Sec.  141.330(a) to require 
compliance with 33 CFR part 183.
    The Coast Guard acknowledges that, for practical purposes, 
recreational boats complying with 33 CFR part 183 will commonly be used 
as skiffs, but we

[[Page 40053]]

share the commenters' concern regarding the potential for confusion 
regarding the requirements for skiffs that are used as survival craft. 
The Coast Guard has revised Sec.  141.330 to--
     Clarify that skiffs may only be used as survival craft by 
towing vessels that do not operate more than 3 miles from shore,
     Include the source of the requirements for safe loading 
and capacity information (33 CFR 183.23), and
     Correct a source reference for marking requirements in 
paragraph (f) to match the same source we listed in Sec.  141.315 for 
survival craft.
    The same commenter noted that equipment referred to in proposed 
Sec.  141.330(g) would be approved under 46 CFR part 159, not part 141, 
suggested that we edit proposed Sec.  141.330(g) to prohibit the 
carriage of skiffs after December 31, 2014, unless the craft ensures 
that no part of the individual is immersed in water.
    The Coast Guard agrees that reference to the approval of survival 
craft is inappropriate in part 141, and has removed proposed paragraph 
(g). Additionally, we have revised the title of Sec.  141.330 from 
``Other survival craft'' to ``Skiffs as survival craft.''
    A commenter also suggested that we not impose size requirements on 
a skiff because the entire tow or the towing vessel could usually make 
it to shore for evacuation purposes in any type of catastrophic event, 
or alternatively we should include an inflatable raft as an ``other 
survival craft.''
    As already discussed in the context of Sec.  141.305, towing 
vessels operating in limited geographical areas or on rivers within 1 
mile of shore are only required to carry survival craft if the 
cognizant OCMI determines that they are necessary. However, in other 
operating areas where we cannot assume that the vessel can make it to 
shore, a skiff used as a substitute for a survival craft must be 
capable of carrying all personnel onboard. As reflected in both Sec.  
141.330 and footnote 2 of table 141.305, vessels that operate more than 
3 miles from shore may not use a skiff as a substitute for a survival 
craft except for those operating in warm water on the Great Lakes or 
Lakes, Bays and Sounds.
    One commenter listed several factors that should be considered when 
approving existing and new ``skiffs.''
    However, the Coast Guard does not intend to ``approve'' skiffs. 
Provided that the skiff meets the requirements of Sec.  141.330, it may 
be used as a substitute for approved survival craft, as reflected in 
Table 141.305.
    The same commenter cautioned against using the terms ``skiff'' and 
``rescue boat'' interchangeably for fear of confusion between the 
functions of these boats.
    As discussed earlier in this preamble, the Coast Guard acknowledges 
the commenter's concerns and has added a definition for rescue boat in 
Sec.  136.110. To further reduce confusion, we have removed the 
proposed references to rescue boat in Sec. Sec.  137.220 and 140.405, 
but retained them in Sec.  140.420 to leave training or drill 
requirements in place for towing vessels that use a rescue boat.
    Regarding the sections for lifejackets, immersion suits, and 
lifebuoys (Sec. Sec.  141.340, 141.350, and 141.360, respectively), an 
individual noted that these sections do not contain provisions for 
vessels electing the Coast Guard inspection option.
    We disagree. Sections 141.340, 141.350, and 141.360 do contain the 
requirements for all towing vessels, whether they elect the Coast Guard 
inspection option or the TSMS option.
    We received several comments concerning lifejackets. Four 
commenters requested clarification of the requirements for lifejackets 
at watch stations. Three maritime companies and an association 
suggested that one lifejacket per watchstander be required and made 
accessible. Commenters felt that the requirement to store lifejackets 
at ``watch stations'' is difficult to define for deckhands because they 
are mobile; one commenter stated that the term ``watch station'' needs 
to be defined.
    The Coast Guard does not believe that we need to define ``watch 
station,'' but we make clear that lifejackets must be immediately 
available to those standing watch as well as to other crew. The bridge 
and the engine control room are examples of watch stations. As 
specified in Sec.  141.340(b), for towing vessels with berthing aboard, 
lifejackets would need to be immediately available for watchstanders 
there as well as at other manned watch stations.
    Two commenters asserted that the COI should list the total number 
of persons allowed on a vessel and state the same number of lifejackets 
and space in a survival craft be available.
    An inspected vessel's COI will state the total number of persons 
allowed on the vessel as well as applicable lifesaving equipment that 
is required onboard the vessel. These numbers are based on 
determinations made by the OCMI issuing the COI.
    One commenter suggested that crew on manned barges in the Great 
Lakes, over 3,000 GRT, should not be required to have work vests 
because the personnel mostly remain on the barge, which is more stable 
than a tug. One commenter suggested that the requirement to provide 
both life jackets and work vests is redundant.
    The Coast Guard agrees that the proposed Table 141.335 may have 
been misinterpreted to mean that work vests were required to be carried 
as personal lifesaving equipment. Under Sec.  140.430, work vests are 
not required, but are one of three options for use by personnel 
dispatched from the vessel or working in an area without rails or 
guards. We clarified Sec.  140.430 and removed Table 141.335, as 
discussed above, and we have clarified Sec.  140.430 to indicate the 
appropriate use of work vests.
    Another towing company recommended that proposed Sec.  141.335 
should clarify that immersion suits are not required on towing vessels 
that travel along inland or Western Rivers. The commenter noted that 
proposed Table 141.335 indicated that immersion suits are not required 
on vessels travelling on limited geographic areas or rivers, but it 
does require immersion suits on vessels travelling on lakes, bays, and 
sounds and that there are many lakes that fit subchapter M's definition 
of lakes, bays, and sounds along the inland and Western Rivers that are 
simply part of a vessel's route, or an area to drop off barges.
    The Coast Guard disagrees with this recommendation. In our 
immersion suit requirements in Sec.  141.350, the allowance for towing 
vessels operating on rivers or in limited geographical areas to not 
carry immersion suits assumes that rescue or emergency assistance would 
be close at hand, thus limiting the duration that a person would be 
immersed in cold water. We cannot make this same assumption on lakes, 
bays, and sounds. We have not made changes from the proposed rule based 
on this comment.
    The Coast Guard removed proposed Sec.  141.335 and Table 141.335 
because they contained the same information as Sec.  141.340 and Sec.  
141.350.
    We revised proposed Sec.  141.340(d), now Sec.  141.340(c), to 
clarify that the option to use alternative means to comply with the 
lifejacket requirements also applies to non-TSMS vessels, and to cross 
reference back to Sec.  141.225.
    Several commenters, including maritime companies, suggested that a 
paragraph be added to note that lifejackets that are stored on open 
racks, where the jackets are clearly seen, do not need labels.
    The Coast Guard agrees that clarification was necessary, so we have 
revised and consolidated proposed Sec.  141.340(e) and (f) into new 
Sec.  141.340(h) to make clear that the

[[Page 40054]]

stowage location marking requirements only apply to lifejackets stowed 
in a berthing space, stateroom, or lifejacket container, including 
those stored in racks in these types of interior spaces. The Coast 
Guard has made additional editorial revisions to this section to remove 
redundancies and to locate all lifejacket requirements in this section, 
rather than cross-referencing 46 CFR subchapter W, and we have made 
amendments to Sec. Sec.  199.01 and 199.10 of subchapter W, to clarify 
that subchapter W does not apply to towing vessels. We also numbered 
the rows of Table 199.10(a), to aid any possible future edits.
    A towing company suggested amending proposed Sec.  141.340(d) to be 
consistent with TSAC recommendations for stowing lifejackets. This 
particular TSAC recommendation refers to the TSMS option which allows 
alternative means to meet the requirements of this section, and also 
outlines language requiring the approved TSMS to specify the number and 
location of lifejackets to facilitate immediate accessibility at 
normally occupied spaces.
    The Coast Guard has reviewed the TSAC recommendations and its 
proposed edits to draft regulatory text related to lifesaving 
requirements in their entirety and confirm that our revisions to 
proposed Sec.  141.340(d) (now Sec.  141.340(c)) are consistent with 
those recommendations.
    We received comments from maritime companies and an association 
that recommended that the requirement for posting of placards with 
information regarding use of lifejackets be deleted, and that 
information in another format be provided on the vessel instead.
    While the Coast Guard believes that proper donning and use of the 
PFD plays a large part in survival, we note that this information is 
covered by the safety orientation required by Sec.  140.410(b). 
Accordingly, Sec.  141.345 has been removed from this rulemaking.
    One commenter recommended that, at a minimum, each towing vessel 
should be required to furnish a throwable flotation lifesaving device 
on the end of each barge or tow available and ready for use at all 
times to rapidly retrieve a person who falls overboard. The commenter 
noted that without a ``lifebuoy'' or equivalent, if a person falls 
overboard from a single barge tow, the nearest throwable lifesaving 
device may be on the towboat itself and may be 100 to more than 1,000 
feet and minutes away.
    The Coast Guard recognizes the commenter's concern, but the comment 
is outside the scope of this rulemaking. We note that on September 10, 
2014, the Coast Guard published a final rule entitled, ``Lifesaving 
Devices--Uninspected Commercial Barges and Sailing Vessels'' (79 FR 
53621). In the course of that rulemaking, we discussed and evaluated 
the feasibility of requiring lifebuoys on barges, and found the costs 
to outweigh the benefits. However, vessel owners or managing operators 
may opt to carry additional approved lifebuoys for this purpose.
    A mariner's association and an individual believed that efforts 
towards the protection of personnel from cold weather should include 
the requirement of anti-exposure work suits for water temperatures 
below 59 degrees Fahrenheit, as cited in the NVIC 7-91. One commenter 
suggested that NVIC 7-91 be rewritten to include ``cold water'' areas 
found on navigable rivers in addition to its present coastwise 
coverage.
    Consistent with recommendations in NVIC 7-91, we proposed in Sec.  
141.350 to require immersion suits for towing vessels that operate 
north of latitude 32[deg] N. or south of latitude 32[deg] S. if the 
vessel does not operate exclusively on rivers or in a limited 
geographic area. At these latitudes water temperatures drop below 59 
degrees Fahrenheit during a typical year. While the Coast Guard agrees 
that anti-exposure work suits of the type approved by the Coast Guard 
under approval series 160.053 or 160.153 provide valuable thermal 
protection to workers on deck, they are not intended to get wet. 
Immersion suits are specially tested and approved for thermal 
protection during prolonged immersion in cold water. As in Sec.  
141.340(c) above, we revised the text in paragraph (a)(3) to clarify 
that the option to use alternative means to comply with the immersion 
suit requirements also applies to non-TSMS vessels and to cross 
reference back to Sec.  141.225.
    We received several comments, from maritime companies and others, 
requesting proposed Sec.  141.360(a)(1) be deleted because subchapter M 
does not apply to vessels less than 26-feet long.
    The Coast Guard does not agree. Section 136.105 makes subchapter M 
applicable to towing vessels of less than 26 feet if the towing vessel 
is pushing, pulling, or hauling a barge that is carrying oil or 
hazardous material in bulk, and the requirement in Sec.  
141.360(a)(1)--to carry a minimum of one lifebuoy of not less than 510 
millimeters (20 inches) in diameter--applies to those towing vessels.
    We received several comments from maritime companies and 
associations suggesting that the required number of lifebuoys on towing 
vessels be consistent with industry practice. On towing vessels of less 
than 79 feet, they suggested reducing the required number of lifebuoys 
to two from the proposed number of three. On towing vessels of more 
than 79 feet, they suggested requiring four, in lieu of what we had 
proposed, which was four, plus one on each side of the primary 
operating station and one at each alternative operating station if the 
vessel is so equipped.
    The Coast Guard agrees that two lifebuoys are appropriate for a 
towing vessel between 26 and 79 feet in length, and has reduced the 
required number accordingly in amended Sec.  141.360(a)(2), consistent 
with lifesaving regulations for inspected vessels of similar size. 
Similarly, the Coast Guard agrees that the proposed text appears to 
require more lifebuoys than is practical on a towing vessel of more 
than 79 feet in length, and has amended Sec.  141.360(a)(3) to clarify 
the requirement by stating the minimum number of lifebuoys and their 
placement independently. Also, we removed reference to primary and 
alternative operating stations. Vessels with more than one operating 
station will now be required to carry lifebuoys on each side of any 
operating station, as practicable. We are aware that some of the 
operating stations may have limited space available or may not have a 
way to access the sides. In these cases, owners and operators need to 
work with the local OCMI to determine an acceptable equivalent for the 
operating station concerned.
    As above in Sec. Sec.  141.340(c) and 141.350(a)(3), we revised the 
text in Sec.  141.360(a)(4) to clarify that the option to use 
alternative means to comply with the lifebuoy requirements also applies 
to non-TSMS vessels and to cross reference back to Sec.  141.225.
    Other commenters, including an association and an individual, 
recommended that Sec.  141.360 require a specific commercially 
available throwable PFD, instead of the traditional ``lifebuoy'' 
because lifebuoys can only be thrown a relatively short distance.
    The Coast Guard has revised Sec.  141.360 to allow for throwable 
devices approved under approval series 160.050 or 160.150 to satisfy 
the prescriptive requirements of this section, provided that the vessel 
is not subject to SOLAS. An approved lifebuoy, or another throwable PFD 
approved under approval series 160.050 or 160.150 as equivalent to a 
lifebuoy, would satisfy this requirement. Consistent with specifying 
performance objectives when possible, rather than specifying the 
behavior or manner of compliance that

[[Page 40055]]

regulated entities must adopt, we did not adopt the commenter's 
suggestion that we require a specific commercially available throwable 
PFD.
    Regarding proposed Sec.  141.360(b), a company suggested that the 
reference to release of lifebuoys in Sec.  199.70(a)(1)(v) would not be 
necessary for most towing vessels, particularly those operating on 
inland waters. Some commenters also felt that the wording for Sec.  
141.360(b)(2) should be rewritten but did not provide suggestions.
    The Coast Guard agrees that the requirements of Sec.  
199.70(a)(1)(v) is not the most appropriate for towing vessels, and 
further notes that the cross reference to Sec.  199.70 in Sec.  
141.360(b) creates unnecessary confusion as to which requirements 
apply. The Coast Guard has revised Sec.  141.360 to remove the 
reference to Sec.  199.70(a) and to include only those requirements 
that are intended to apply to lifebuoys on towing vessels.
    Three commenters felt that Sec.  141.360(b)(2) should be amended to 
clarify that floating electric water lights are not required for towing 
vessels operating solely on Western Rivers.
    The Coast Guard does not agree. The fitting of lights to lifebuoys 
increases the likelihood that the person in the water will be located 
and retrieved, irrespective of the operating area. However, under 
revised Sec.  141.360(c)(2) and (3), the floating electric water light 
is not required for towing vessels limited to daytime operations.
    An individual indicated that the proposed rule did not clearly 
state the floating electronic water light should not be attached to the 
lifeline.
    As noted in Sec.  141.360(c)(4), the floating electric water light 
is to be secured around the body of the lifebuoy, which is consistent 
with language applicable to other inspected vessels. The Coast Guard 
feels that this language in Sec.  141.360(c)(4) is clear.
    One commenter felt that using millimeters in proposed Sec.  
141.360(b)(3) was unnecessary and could result in an inspector 
rejecting a lifeline if he or she determined it is only 908 mm in 
length instead of the required 910 mm. The commenter suggested that we 
use meters instead of millimeters.
    The Coast Guard does not agree. The millimeter equivalents to the 3 
and 6 foot standards in the corresponding paragraph of this final rule, 
Sec.  141.360(c)(3), are consistent with similar regulations for other 
inspected vessels. See, for example, 46 CFR 117.70 and 180.70. The more 
precise metric equivalent leaves less of a gap between it and the 
English units. The Coast Guard does not see a compelling reason to use 
a different standard for similar requirements on other types of 
inspected vessels.
    One commenter suggested that the number of alternative lifebuoys be 
left to the OCMI to decide.
    As noted above, we have reduced the number of lifebuoys below what 
we proposed in the NPRM. We do not believe an appropriate level of 
safety is met by further reducing that number. Under Sec.  141.225, 
however, the OCMI may require additional lifebuoys as deemed necessary 
based on the operating area.
    Lastly, an individual asserted that in order to quickly identify 
lifebuoys as safety equipment, all lifebuoys should be colored orange.
    The Coast Guard believes that lifebuoys are readily recognized as 
lifesaving equipment, regardless of color. However, in Sec.  
141.360(b)(5) we require that lifebuoys must be orange on vessels on an 
oceans or coastwise route, where visibility could be obscured by white 
caps.
    One commenter pointed out that proposed Sec.  141.365 includes 
procedures in the TSMS for the prompt recovery of a person from the 
water, and for the training of crewmembers responsible for recovery in 
effectively implementing such procedures, applies only to towing 
vessels under a TSMS and not to vessels that elect Coast Guard 
inspection. This commenter recommends that the rule also address this 
issue for towing vessel choosing the Coast Guard inspection option.
    The Coast Guard does not agree with requiring these written 
procedures for those vessels choosing the Coast Guard option. Vessels 
choosing the Coast Guard option will be required to get underway to 
conduct drills for a Coast Guard inspector and the retrieval of a man-
overboard may be required as part of these drills. Therefore, the 
procedures and training will be examined through practice rather than 
through audit of the SMS. However, we did find that proposed Sec.  
141.365 was redundant with Sec.  138.215 and removed it from the final 
rule.
    We received two submissions from commenters requesting we add a 
requirement for specific commercially available person-overboard 
recovering equipment. One commenter said that recovery equipment to 
receive unconscious personnel from water should be required.
    The Coast Guard is not in the position to require carriage of a 
specific commercial product. Based on these comments, however, we have 
added text to Sec.  141.200 to allow a towing vessel to carry 
additional lifesaving equipment in addition to that required under 
subchapter M and that this excess equipment need not be Coast Guard 
approved. We do not see a need to require the person-overboard 
recovering equipment, in addition to the lifesaving equipment required 
in this rule.
    One commenter recommended a public hearing to discuss the 
lifesaving equipment approval process within the Marine Safety 
Directorate, and to agree on what changes can encourage innovative 
lifesaving devices for commercial vessels.
    This recommendation is outside of the scope of this rulemaking, as 
this rule applies only to the carriage of approved lifesaving 
appliances on towing vessels, and does not address the process by which 
that equipment is approved. We have made no changes from the proposed 
rule based on this comment.
    We received several comments suggesting edits to the Miscellaneous 
Lifesaving Requirements table, Table 141.370. We received two comments 
from maritime companies, suggesting amendments to the table clarifying 
which vessels require six flares and which require 12. One association 
suggested that in order to be consistent with other table styles, 
instead of the three columns for Emergency Position Indicating Radio 
Beacon (EPIRB) stating ``Yes'', the columns should just indicate ``1''.
    The Coast Guard agrees that our proposed Table 141.370 is 
confusing. We have made appropriate revisions to the table and the 
regulatory text of the first section it references, Sec.  141.375.
    One commenter recommended that the table in this section include 
``Rivers and Canals'' as an area of operation.
    As we said in response to the same comment regarding Table 141.305, 
the definition of ``rivers'' in Sec.  136.110, which applies to the 
term used throughout subchapter M, includes canals. We have made no 
changes from the proposed rule based on this comment.
    Several commenters suggested that ``excepted towing vessels'' 
operating solely on Rivers or Western Rivers be exempt from carrying 
distress signals. We received several comments, mainly from individuals 
and maritime companies, who felt that the visual distress signals 
should not apply to Western Rivers or inland river systems. Another 
commenter felt that flares and smoke signals required in proposed Sec.  
141.375(b) were not needed for vessels operating on rivers one mile 
wide. A maritime company disagreed with the requirement for single 
flares on harbor and fleeting tugs.

[[Page 40056]]

    The Coast Guard does not agree. The carriage, proper stowage, 
training, and use of visual distress signals influence survivability of 
the crew in the event of an emergency that would require evacuation. As 
we noted above, time to rescue is influenced by the ability to detect 
persons in distress. If there is insufficient evidence that crewmembers 
are in trouble, it is less likely they will receive the assistance they 
need.
    One commenter felt that phrases such as, ``approved under 46 CFR 
subpart 160.021 or other standard specified by the Coast Guard'' is 
vague and should instead reference approval series found in 46 CFR 
199.30.
    The Coast Guard agrees and has revised the regulatory text in part 
141 to specify the approval series applicable to all lifesaving 
equipment required to be approved. The Coast Guard believes that 
specifying the appropriate approval series assists the vessel owners 
and managing operators in determining whether specific equipment is 
approved for a particular application.
    We received several comments, particularly from maritime companies, 
suggesting the deletion of Sec.  141.380(c), which requires 
identification markings on each EPIRB.
    The Coast Guard does not agree. When we find an unattended EPIRB, 
it is important that we know what vessel it came from, so that we can 
mount a more focused and effective rescue response.
    One company requested an exception from the EPIRB requirement for 
vessels operating within coastal bays or sounds that may occasionally 
operate at greater than 3 miles from shore.
    In Sec.  141.380, we did propose to require EPIRBs on vessels 
operating upon the Great Lakes beyond 3 nautical miles from shore but 
not on vessels operating on lakes, bays, and sounds. The Coast Guard 
acknowledges the conflict between Sec.  141.380 and Table 141.370, and 
has made the appropriate revisions to the table to exclude vessels on 
lakes, bays, and sounds from the EPIRB requirement.
    One commenter stated that the requirement for EPIRBs does not 
mention requirements for hydrostatic release.
    We note that Sec.  141.380(b) requires that the EPIRB be mounted 
such that it will float free if the vessel sinks. Hydrostatic release 
is one of several methods for meeting this requirement. We made no 
changes from the proposed rule based on this comment.
    One commenter suggested that Sec.  141.380(a) be consistent with 
NTSB Recommendations M-10-1 and suggested that each EPIRB installed 
after the effective date of these rules should be a type which includes 
a satellite position in its distress alert.
    The Coast Guard recognizes the merit of enhanced locating devices, 
but the benefit of adding enhanced GPS locating functionality to an 
EPIRB does not outweigh the costs associated with making it mandatory 
for all towing vessels, particularly before it is mandatory for other 
types of inspected vessels. Though the Coast Guard may consider this 
matter holistically in the future, we have not made changes to the 
proposed rule based on this comment. However, this does not preclude a 
vessel operator from optionally carrying such equipment.
    We received comments from three maritime companies that felt that 
because a tug is able to retrieve a barge without boarding, and because 
boarding a drifting barge is dangerous, the line throwing requirement 
in Sec.  141.385 is not needed.
    The Coast Guard notes that the line-throwing appliance was only 
proposed to be carried on towing vessels operating on ocean routes, and 
is not necessarily intended for boarding a drifting barge. The line-
throwing appliance can be used to pass a line to another vessel if the 
towing vessel is incapacitated and needs to be towed.
    One association suggested broadening the line throwing apparatus 
requirement to include towing vessels in coastwise service that operate 
beyond the boundary line.
    The Coast Guard agrees that vessels in coastwise service will be 
subject to similar conditions, and have expanded this requirement to 
include them, consistent with other inspected vessels (see 46 CFR 
199.170 and 199.610). We have amended Sec.  141.385 accordingly.

L. Fire Protection (Part 142)

    The fire protection standards proposed in Part 142 retained most of 
the fire protection regulations that currently apply to towing vessels 
and are contained in 46 CFR parts 25 and 27. The public comments 
received in response to proposed part 142 provided a number of 
suggestions aimed at improving the clarity of the requirements based on 
several years of operating experience with the current regulations. We 
have incorporated many of these suggestions in an effort to make part 
142 more user-friendly, and made additional editorial revisions to 
improve clarity and readability. We also received some comments 
critical of specific provisions in the NPRM. Most notable are 
objections to the requirements for flammable liquid storage cabinets on 
inland towing vessels, the use of portable fire pumps, the requirements 
for a professional engineer (P.E.) to certify fire detection systems, 
and any requirements relating to onboard fire-fighting. Each of these 
comments is discussed in greater detail in the following item-by-item 
responses.
    In general, the nature of the public comments made it clear to us 
that the organization of part 142 was confusing and could be greatly 
improved by placing in subpart B all of the general requirements that 
are applicable to all towing vessels--such as equipment approvals, fire 
hazards to be minimized, storage of flammable liquids, portable fire 
extinguishers, firefighter's outfits, fire axes, and maintenance and 
training--and placing in subpart C the specific requirements for fire-
extinguishing and fire detection systems applicable only to certain 
vessels. Accordingly, we reorganized part 142 by deleting redundant 
requirements for fixed fire-extinguishing systems in proposed Sec.  
142.235, and moving the requirements for portable fire extinguishers 
from proposed Sec.  142.305 to Sec.  142.230(d), the requirements for 
firefighter's outfits from proposed Sec.  142.350 to a new Sec.  
142.226, and the requirements for fire axes from proposed Sec.  142.350 
to a new Sec.  142.227, but we did not change any requirements, except 
in response to public comments as discussed in the following 
paragraphs. Section 142.235 in this final rule now contains 
requirements for vessels contracted for prior to November 19, 1952.
    With respect to proposed Sec.  142.105 on applicability, one 
commenter requested that we add text to indicate that vessels exempted 
from 46 CFR part 27--which currently applies to most towing vessels 
that will become subject to subchapter M requirements--need not comply 
with part 142. We partially agree with this commenter. In Sec.  
142.300, we have established that excepted vessels need not comply with 
the provisions of subpart C regarding fixed fire-extinguishing 
equipment; our definition of ``excepted vessels'' in Sec.  136.110 
includes many of the vessels excluded from part 27 applicability by 
Sec.  27.100(b).
    But, we do not agree that these vessels should be exempt from the 
general fire safety provisions in subparts A and B. These requirements 
implement minimum standards for portable fire extinguishers and control 
of combustible materials, which we believe are essential on board all 
vessels. Accordingly, we did not adopt the broad exemption recommended 
by the commenter.

[[Page 40057]]

    We revised Sec.  141.205(a) to include a reference to SOLAS Chapter 
II-2 as this is where specific fire protection requirements are 
contained.
    With respect to Sec.  142.215, one commenter suggested that the 
installation of excess fire-fighting and fire detection equipment on a 
vessel must be designed, constructed, installed and maintained in 
accordance with recognized industry standards acceptable to the Coast 
Guard. We agree with this comment and have added a paragraph (c) to 
this section to address equipment that is installed but not required by 
this subpart. Because there may be existing vessels affected by this, 
we have included provisions that allow the local OCMI to accept 
existing equipment of any design as long as it is determined to be in 
serviceable condition. Additionally, we have clarified the wording 
regarding approved equipment in order to standardize this language 
throughout the subchapter.
    Several commenters expressed concern that the proposed requirements 
in Sec.  142.220 appeared to prohibit the presence of any combustible 
and flammable liquids in the bilges at any time. They noted that the 
accumulation of some amounts of combustible and flammable liquids in 
the bilges is unavoidable during normal operations, and requested 
changes to this section. We agree that small amounts of such liquids 
are likely to be present; however, we also want to clearly express our 
concerns over the accumulation of considerable quantities of liquids 
that could be a fire hazard. We therefore modified the text of Sec.  
142.220(a) to indicate that the bilges should be kept as clear as 
practical.
    Another commenter felt that the proposed requirements in proposed 
Sec.  142.220(c) (now Sec.  144.415) for the insulation of exhaust 
pipes and galley cooking equipment exhaust ducts should apply only to 
new vessels because it would be difficult to retrofit existing vessels, 
and the risk does not warrant added protection. We do not agree with 
this commenter, and have not changed the requirement. There have been 
recent exhaust system fires (discussed in our Safety Alert 05-08, dated 
September 17, 2008) in which the cause was attributed to the 
installation of new diesel engines that run at hotter temperatures than 
previous models. We believe that the potential fire risk is the same on 
both new and existing vessels. However, to alleviate concerns about 
installing insulation on the exhaust systems of existing vessels, we 
have added to Sec.  144.415 two alternate methods of demonstrating 
compliance. The revised requirement would accept exhaust systems 
designed to either Standard P-1 of the American Boat and Yacht Council 
(ABYC) or Standard 302 of the National Fire Protection Association 
(NFPA) as equivalent forms of protection. These additional means of 
protection will provide operators of existing vessels a wider range of 
choices to comply with the rule. As noted above, proposed Sec.  
142.220(c) was moved to Sec.  144.415 as this requirement is more 
closely related to part 144.
    We received several comments objecting to requirements in Sec.  
142.225 for approved flammable liquids storage cabinets on boats 
operating on the Western rivers. These commenters appear to have 
misinterpreted the proposed rule. We proposed that combustible and 
flammable liquids be stored in a controlled area, either a specific 
room or a dedicated storage cabinet. An approved storage cabinet is an 
option and not a required piece of equipment. Related to this, one 
commenter recommended that we also accept flammable liquid storage 
cabinets that are Factory Mutual approved. We agree with the commenter 
that Factory Mutual cabinets provide an equivalent level of safety as 
those approved to UL 1275, a voluntary consensus standard used in the 
NPRM and this final rule, and have added a new Sec.  142.225(c)(2) to 
accept their use. Another commenter felt that securing the cabinets to 
the vessel should not be required on the Western Rivers, but offered no 
justification for the comment. We acknowledge that vessels operating on 
the river system are subject to less significant wind and wave motions 
than are experienced by ocean-going vessels, but do not agree with the 
commenter that flammable liquid storage cabinets should be unsecured. 
Any sudden acceleration or movement of the vessel could dislodge the 
cabinet, causing a flammable liquid spill potentially leading to a 
fire. We have not made any changes as a result of this comment.
    Finally, we received one comment suggesting that Sec.  142.225 
should contain information on the storage of hazardous material in 
ships' stores. We believe these materials are adequately covered by 
regulations in 46 CFR part 147, which apply to towing and other vessels 
subject to inspection under 46 U.S.C. 3301, and need not be repeated 
here.
    In Sec.  142.226 (proposed Sec.  142.345), and throughout this 
part, we changed all references from fireman to firefighter. We also 
removed the reference to the Mine Safety and Health Administration 
because this agency no longer approves self-contained breathing 
apparatus for normal use. A variety of comments were submitted 
regarding the proposed requirements for the carriage of firefighter's 
outfits covered by proposed Sec.  142.345 (now Sec.  142.226 as noted 
above). One commenter recommended that the proposed standards should be 
enhanced by listing the specific equipment required for each 
firefighter's outfit. Others recommended that the requirements for the 
carriage of firefighter's outfits should be deleted in their entirety, 
since in their opinion it is too dangerous for crewmembers to enter a 
burning engine room, and would be better advised to abandon ship in the 
event of a serious fire.
    We have not removed the requirements for firefighter's outfits. We 
proposed firefighter's outfits for a limited class of vessels. Only 
vessels of 79 feet or more, operating on ocean or coastwise routes, 
that do not have a fixed fire suppression system in the engine room are 
required to carry firefighter's outfits. These vessels are primarily 
existing vessels that were contracted for prior to August 27, 2003. The 
Coast Guard believes that these vessels, which operate on the open 
ocean should have enhanced fire-fighting equipment because timely 
outside assistance is unlikely, and in the event of an engine room fire 
the crew must be able to provide onboard response. Vessel operators 
that believe that fire-fighting poses an unacceptable risk to the crew 
have the option of installing a fixed fire-extinguishing system in the 
engine room.
    One commenter requested changes to Sec.  142.230 that would allow 
two size B-III semi-portable fire extinguishers on smaller vessels to 
substitute for the required B-V extinguisher, which in their opinion, 
is difficult to handle due to its size. We do not agree with this 
comment. As noted in the 2004 Fire-Suppression Systems and Voyage 
Planning for Towing Vessels final rule (69 FR 34064, June 18, 2004), 
the severity of an engine-room fire is not related to the length of the 
vessel, but to the fire hazard present in the engine room. The use of 
marine diesel fuel oil poses a sufficient hazard to warrant the higher 
fire-suppression capability of a size B-V extinguisher. However, we are 
concerned that some operators may be installing semi-portable 
extinguishers that are fitted with wheels. These types of extinguishers 
are intended for use in shore-side applications and, if used on board 
vessels, they need to be secured to prevent possible injury to the 
crew. We have consequently added a supplemental provision to Sec.  
142.230(e) that requires that any extinguishers fitted with wheels must 
be welded or otherwise secured to the vessel.

[[Page 40058]]

    Another commenter noted that because the NPRM splits discussion of 
the fire extinguisher requirements between Sec.  142.230 and proposed 
Sec.  142.305, it was difficult to determine what is actually required; 
the commenter requested a single chart with all of the fire 
extinguisher requirements in one location. We agree with this commenter 
and have relocated all of the portable hand-held fire extinguisher 
requirements to Sec.  142.230(d) and deleted proposed Sec.  142.305. 
The proposed text in Sec.  142.230(d) relating to extinguisher labeling 
and nameplates has also been deleted, since this is an approval 
requirement covered by 46 CFR 162.028-3(f) and 162.028-4, and is not 
appropriate for inclusion here. Requirements for semi-portable B-V fire 
extinguishers remain in Sec.  142.315.
    As previously noted in the general discussion of Part 142, we have 
deleted the content of proposed Sec.  142.235 because it contained a 
superfluous requirement that fixed fire-extinguishing systems must be 
approved by the Commandant, which is already required by Sec.  
142.215(a). We also deleted the requirement that carbon dioxide systems 
must be designed in accordance with 46 CFR part 76, subpart 76.15, 
because this is covered in the definition of ``fixed fire-extinguishing 
system'' in Sec.  136.110.
    One commenter suggested that all new installations of fixed fire-
extinguishing systems should be required to undergo plan approval by 
the Coast Guard prior to installation. We do not agree with this 
comment and have not changed the proposed rule to require plan approval 
by the Coast Guard. We believe requirements in Sec.  144.135 are 
sufficient. That section requires verification of compliance with 
construction and design standards before a new installation that is not 
a replacement in kind may be installed. We changed the inspection and 
testing criteria in Table 142.240 to harmonize this regulation with the 
Carbon Dioxide Fire Suppression Systems on Commercial Vessels final 
rule (77 FR 33860, June 7, 2012), a separate rule related to fire 
suppression systems on commercial vessels that was published after we 
published our NPRM. We made reference to that ongoing rulemaking and 
its potential impact on this rule in our NPRM. See 76 FR 49985, Aug. 
11, 2011. The Carbon Dioxide Fire Suppression rule revised the vessel 
regulations to require lock-out valves and odorizing units on all new 
carbon dioxide extinguishing systems installed or materially altered 
after July 9, 2013. That rulemaking also changed each of the vessel 
subchapters to allow the use of clean agent fire-extinguishing systems 
as an alternative to carbon dioxide systems. Because of this, it was 
necessary to change the inspection and testing requirements for fire-
extinguishing systems in Table 142.240 to include criteria for the 
inspection and testing of the new clean agents. We have also slightly 
modified the definition of ``fixed fire-extinguishing system'' in Sec.  
136.110 to comport with the revised definition in new 46 CFR 27.101.
    Additionally, we changed ``maintain'' to ``test and inspect'' in 
the water mist ``test'' field in Table 142.240, to more accurately 
reflect the intent of this requirement.
    Several comments related to the proposed regulatory text in Sec.  
142.240 revealed that this section was confusing and did not clearly 
convey our intended requirements. During our further review of proposed 
Sec.  142.240 we noted that the NPRM used inconsistent wording and 
tended to use the terms ``examination,'' ``test,'' and ``maintenance'' 
interchangeably, which contributed to the confusion. We have, 
therefore, revised the text and format of this section to improve its 
clarity and consistency. All testing and inspection requirements are 
stated in paragraph (a), all maintenance requirements are in paragraph 
(b), and requirements for recordkeeping are in paragraph (c). We have 
also replaced the word ``examination'' with ``inspection'' to be 
consistent with other Coast Guard regulations.
    We received numerous comments requesting that the proposed text of 
this section be modified to require fire suppression and fire detection 
systems be inspected or tested annually or in accordance with the TSMS 
applicable to the vessel. We agree with this view and have changed 
Sec.  142.240(a) to require inspection or testing at least every 12 
months--as we proposed in Sec.  142.240(c)--or more frequently, if 
required by the vessel's TSMS.
    Several comments also proposed that the TSMS should be the 
exclusive form of recordkeeping for test and inspection results. We do 
not agree with this comment. For flexibility, we have proposed that the 
records may be kept in accordance with an applicable TSMS, the TVR, or 
the vessel's logbook, whichever applies. We have also added new 
provisions in Sec.  142.240(c)(2) to accept service tags attached to 
portable and semi-portable extinguishers by a qualified servicing 
organization as an acceptable record that demonstrates the required 
tests and inspections have been completed.
    One commenter requested that we replace the phrase ``dampers'' in 
proposed Sec.  142.240(c), now Sec.  142.240(a), with ``fire dampers.'' 
It was not our intent to require the testing of fusible-link fire 
dampers. The proposed requirement was directed at pressure-operated 
dampers installed in engine room ventilation ducts. These dampers are 
automatically operated by the engine room fire-extinguishing system, 
and must close prior to system discharge to prevent the leakage and 
dilution of the fire-extinguishing agent. To clarify what dampers we 
intended to be tested, we have changed ``dampers'' to ``fixed fire-
extinguishing system pressure-operated dampers.'' We have also added 
this phrase to Sec.  142.240(a)(5) to clarify that these dampers must 
be tested as part of the fire-extinguishing system inspection 
procedures.
    One commenter requested a modification to the carbon dioxide 
cylinder tests required by Table 142.240 that would remove the 
requirement to weigh the cylinders, and in its place permit the use of 
liquid level indicators. We do not agree with this requested 
modification. The Coast Guard has historically required that carbon 
dioxide cylinders must be weighed to determine the amount of 
extinguishing agent (see, e.g., 46 CFR 91.25-20(a)(2) and related 
table), because weighing is the only reliable method to check the 
quantity of carbon dioxide in the cylinders that the Coast Guard 
recognizes. Liquid level measuring systems use various types of sensing 
elements that show the location of the liquid/gas interface within the 
cylinder. With that knowledge, a technician is able to calculate the 
quantity of agent. We have no objection to the use of liquid level 
indicators for checking the quantity of halocarbon clean agents, 
because a liquid/gas interface can be easily determined. This is not 
the case with carbon dioxide, however, which has a critical temperature 
of 87.8 degrees Fahrenheit. Below the critical temperature, carbon 
dioxide in a closed container may be part liquid and part gas. Above 
the critical temperature it is entirely gas, making the use of such 
measuring devices impractical.
    One commenter requested that we change Sec.  142.245 to require all 
records of training and drills to be kept in the TVR. We do not agree 
and have made no changes from the proposed rule based on this comment. 
For flexibility, we have permitted several acceptable recordkeeping 
methods, in accordance with part 140 of this subchapter.
    One commenter questioned the intended extent of the fire detection 
and alarm system testing during drills required by proposed Sec.  
142.245(c)(3). As proposed, the commenter noted, each

[[Page 40059]]

drill could be understood to require a complete test of the system. 
This is not our intent. We anticipate that during drills, only the test 
switch or a single detector needs to be activated to familiarize the 
crew with the system's operation, and have changed the text of Sec.  
142.245(c)(3) to require that only one device needs to be tested.
    One commenter requested that the proposed requirements in this 
section for training crews to respond to fires should be removed from 
the rule, as the limited scope of the training would not afford crew 
members with the necessary skills and knowledge to safely engage in 
fire-fighting activities. The commenter anticipated that this may 
result in a false sense of security, leading to injuries for 
crewmembers attempting to fight engine room fires. Further supporting 
this argument, it was suggested that the typical practice on inland 
towing vessels in response to a fire is to attempt ``first-aid'' 
firefighting using portable extinguishers or fire hoses. If this fails 
to contain the fire, the crew would abandon ship to the tow or the 
riverbank.
    Another commenter requested that we strengthen the training 
requirements by mandating that all licensed officers, apprentice mates, 
steersmen, and engineers complete formal fire-fighting training 
courses.
    We considered comments on these same issues in a previous 
rulemaking, the Fire-Suppression Systems and Voyage Planning for Towing 
Vessels interim rule (68 FR 22607, April 29, 2003), and believed at 
that time that the level of training proposed in our Inspection of 
Towing Vessels NPRM would provide crew members with adequate knowledge 
of the procedures and equipment on board their vessels needed to 
respond to fires; we have not changed our opinion on this issue based 
on these comments on Sec.  142.245. In support of our previous 
rulemaking, TSAC had performed an independent analysis of our casualty 
data, which showed that over 80 percent of the reported fires on inland 
vessels had been extinguished by the crewmembers with only seven 
reported injuries. (See USCG-2000-6931-0046, available on 
www.regulations.gov). Further review of the Coast Guard casualty 
reports on the vessels where injuries were reported revealed that most 
of the seven injuries were the result of conditions in the engine room 
(e.g., burns from the fire outbreak) and were not attributable to fire-
fighting efforts.
    As previously discussed, in order to make this regulation more 
user-friendly, we have made various editorial changes here such as 
moving the portable fire extinguisher requirements previously proposed 
in Sec.  142.305 to Sec.  142.230(d). We also revised the section 
heading of Sec.  142.315 to ``Additional fire-extinguishing equipment 
requirements,'' and amended that entire section to make clear which 
provisions did not apply to certain towing vessels. In order to account 
for those vessels operating within 3 nautical miles from shore on the 
Great Lakes, we revised paragraph (a)(1) of Sec.  142.315. These 
revisions did not change any substantive requirements proposed in the 
NPRM.
    We received numerous comments requesting that we modify proposed 
Sec.  142.325(c) to clarify that sufficient hydrants and hoses must be 
provided to allow ``a stream of water from'' a single length of hose to 
reach any part of the machinery space. We concur with these comments 
and have changed the text accordingly. Associated with this were 
several comments that the requirement for a single length of hose 
should be deleted. We do not concur with this, because the single, 15-
meter-length-of-hose requirement ensures that a sufficient number of 
fire hydrants with attached hoses are installed in or close to the 
engine room. If the fire-fighting water could be provided by multiple 
sections of hose linked together, (i.e., a segmented hose of unlimited 
length) a single remote hydrant might satisfy the rule, but the length 
of hose required would either be too cumbersome to handle in an 
emergency, not provide the necessary amount of firefighting water due 
to friction loss, or both.
    One commenter urged us to add a new Sec.  142.325(g) requiring a 
minimum fuel supply stowed onboard to enable 4 hours of operation of 
the portable fire pump. We do not agree with this suggestion. Paragraph 
(b) of 46 CFR 27.211 prohibits the carriage of portable fuel tanks and 
related hardware except when used for outboard engines or when 
permanently attached to portable equipment such as fire pumps. Most 
commercially available portable fire pumps have a fuel tank capable of 
operating the pump for at least 1 hour. The carriage of supplemental 
fuel supplies to allow 4 hours of operation would conflict with the 
provisions of 46 CFR 27.211(b).
    Another commenter requested that we remove the requirement for a 
``self-priming'' portable fire pump and require, as an alternative, 
that a minimum time period be specified during which the crew must be 
able to demonstrate that their portable pump can be deployed. We do not 
agree with this comment and have not removed the requirement for self-
priming pumps, as non-self-priming pumps are extremely difficult to 
successfully operate under emergency conditions.
    A third commenter noted that in his experience, many crews have 
difficulties getting the self-priming feature of portable fire pumps to 
function. We believe this commenter raises a valid point, and have 
added a new paragraph (c)(5) to Sec.  142.245 to require regular 
training on the self-priming feature during fire drills to ensure crew 
familiarity its operation, on vessels equipped with portable pumps.
    Another commenter requested that we not accept the use of portable 
pumps at all, as they are not comparable to fixed fire main systems, 
and the amount of time it takes to assemble and deploy the pump in 
darkness or rough weather could compromise mariner safety. We do not 
concur with this comment because portable pumps were previously allowed 
for uninspected towing vessels and we do not have data supporting the 
removal of the option of using cost-effective portable fire pumps. 
Operators with vessels on routes or in services where the ability to 
deploy and operate portable pumps could be difficult may choose to 
install a fixed fire main system as an option.
    One commenter recommended that we specify the type of fire hoses 
required by this section, and urged that we adopt UL 19 as the required 
standard. We believe that the existing requirement for lined commercial 
fire hose provides suitable fire-fighting equipment for this purpose. 
Firehose meeting UL 19 is constructed to a higher standard that would 
impose unnecessary costs on the industry.
    One commenter suggested that Sec.  142.325 require a dedicated sea-
chest for the installed fire main. We do not agree with this comment, 
because a dedicated sea-chest would likely be used only during drills 
and in emergencies. If the fire main system is connected to a sea-chest 
that is regularly used for shipboard services, there is a greater 
chance that it will be clear of debris or fouling when needed.
    During our review of the public comments on Sec.  142.330, we noted 
that the proposed introductory paragraph of this section was confusing 
in regard to the fire detection system requirements for towing vessels 
constructed on or after January 18, 2000. We have clarified and 
improved the structure of this section by addressing vessels whose 
construction was contracted for prior to January 18, 2000, separately 
in paragraph Sec.  142.330(a)(8).
    One commenter requested clarification as to whether the audible and 
visual alarms at the operating station required by proposed

[[Page 40060]]

Sec.  142.330(c) must be integral to the fire alarm control panel. The 
Coast Guard's response is that the operating station must have a fire 
detection control panel installed within the space. However, in the 
years since the Fire-Suppression Systems and Voyage Planning for Towing 
Vessels final rule was published (69 FR 34064, June 18, 2004) and 
incorporated into existing 46 CFR subchapter C regulations, we have 
become aware that there may be cases where this is a problem on towing 
vessels with more than one operating station because the fire detection 
system control panel is not installed at each operating station. We did 
not intend to impose an undue economic burden on vessels of this design 
type by requiring fire detection control panels at each operating 
station. Rather, one operating station must be outfitted with the fire 
detection control panel while any others could be outfitted with either 
fire detection control panels or a remote indicator with audible and 
visual alarms. We amended the regulatory text of this section to 
reflect this intent (see new Sec.  142.330(a)(3)).
    Another commenter requested that we remove reference to a circuit-
fault detector test-switch in Sec.  142.330(a)(4)(v) because currently 
available fire alarm control panels use internal supervision instead of 
a test switch to verify circuit integrity. We agree with this comment 
and have changed this paragraph to accept control panels with internal 
circuit supervision as equivalent to those having a test switch. We 
have elected to retain a reference to panels with a test switch to 
allow flexibility in meeting this provision.
    Various commenters suggested that proposed Sec.  142.330(g), which 
we redesignated as Sec.  142.330(a)(7) in the final rule, should be 
amended to allow certification of fire detection systems by the 
National Institute for Certification in Engineering Technologies 
(NICET) Level IV technicians in addition to registered P.E.s. We concur 
with this view and have changed the text of Sec.  142.330(a)(7) 
accordingly. Level IV technicians are required to have at least 10 
years' experience in fire alarm installation and testing and must pass 
a comprehensive written exam to demonstrate their knowledge. Other 
commenters requested that we add a qualifying statement to the 
requirement for a P.E., to ensure that the engineer is qualified to 
review and certify fire detection systems. We agree and have changed 
Sec.  142.330(a)(7) to require that any P.E.s or authorized 
classification society reviewing the system have experience in fire 
detection system design. It is important to note that all required fire 
detection systems must be certified and inspected by a P.E., a NICET 
Level IV Technician, or an authorized classification society including 
those on vessels that elect or are subject to the Coast Guard 
traditional inspection scheme under Sec.  137.200. When the Coast Guard 
inspects the vessel, it will look for evidence that the vessel owner or 
managing operator has had all required fire detection systems on the 
vessel certified and inspected by a P.E., a NICET Level IV Technician, 
or an authorized classification society. We also edited Sec.  
142.330(a)(7) to clearly require the system and its installation to be 
both certified and inspected.
    One commenter requested clarification of proposed Sec.  142.330(g), 
specifically, whether the certifying engineer or technician must review 
only the detection system equipment and layout drawings, or whether it 
is necessary to inspect the installation of the fire detection system 
on board the vessel. We clarified the language in Sec.  142.330, and 
specify that the fire detection system must be both: Certified by a 
P.E., NICET technician, or an authorized classification society 
surveyor to comply with paragraphs (a)(1) through (7) of Sec.  142.330; 
and inspected by a Coast Guard marine inspector or a TPO surveyor, 
depending upon which inspection regime applies to the vessel, to comply 
with Sec.  142.330(a)(2). This last reference requires the system to be 
installed, tested and maintained in accordance with the manufacturer's 
design manual.
    We have substituted the term independent testing laboratory in 
Sec.  142.330(a)(1) and (8) with Nationally Recognized Testing 
Laboratory (NRTL) as defined in 29 CFR 1910.7. The proposed term 
independent testing laboratory is ambiguous and will be replaced with 
NRTL throughout title 46 CFR upon the finalization of a concurrent 
regulatory project (see the Harmonization of Standards for Fire 
Protection, Detection, and Extinguishing Equipment notice of proposed 
rulemaking (79 FR 2254, January 13, 2014)).
    Please note that we have redesignated Sec.  142.335, Smoke alarms 
in berthing spaces, and Sec.  142.340, Heat detector in galley as Sec.  
142.330(b) and (c), respectively, in the final rule. Multiple 
commenters urged us to remove from proposed Sec.  142.335 (now Sec.  
142.330(b)) any requirements for battery operated smoke detectors in 
berthing spaces, and instead require smoke detectors that are part of 
an installed fixed fire-detection system. We do not concur with this 
suggestion. Battery-operated smoke detectors are not required, but 
detectors that meet UL 217 may be used as an alternative to satisfy the 
requirements in new Sec.  142.330(b). We have retained this option in 
the final rule because it offers a low cost alternative to installing a 
fixed detection system in these areas.
    A commenter requested changing proposed Sec.  142.340 regarding a 
heat detector in the galley to require only heat detectors that comply 
with UL 521. We have not specified a specific performance standard for 
the required heat detectors; however, we agree with the commenter that 
only restorable heat sensing type detectors may be used (i.e., 
detectors that automatically reset to operating condition when the heat 
source is removed), and have changed the requirements in redesignated 
Sec.  142.330(c) accordingly.
    In the NPRM we discussed comments submitted in response to seven 
questions we posed in a December 30, 2004, Inspection of Towing Vessels 
notice. In response to that portion of the NPRM, one of these 
commenters recommended applying grandfathering to structural fire-
protection requirements. The commenter also felt that existing vessels 
should be treated differently from newly constructed vessels because of 
the likelihood that fire standards will make it difficult to retrofit 
existing vessels. We have made no changes to the final rule in response 
to this comment. The fire protection standards proposed in this part 
retain most of the fire protection regulations that currently apply to 
existing towing vessels and are contained in Title 46 CFR parts 25 and 
27. Only three new requirements have been added. Section 142.227 
requires all vessels to have a fire axe, Sec.  142.330(b) (proposed 
Sec.  142.335) requires smoke detectors in berthing areas, and Sec.  
142.226 (proposed Sec.  142.345) requires firefighter's outfits on 
certain ocean-going vessels. Battery-operated smoke detectors will be 
permitted, and the addition of fire axes and firefighter's outfits does 
not require any modifications to the vessel; therefore, we do not agree 
that either requirement would be difficult to implement onboard 
existing vessels.

M. Machinery and Electrical (Part 143)

    In this final rule, we made substantive changes in response to 
specific comments on the NPRM, and we also made significant 
organizational changes. Because of the organizational changes, subpart 
headings and section numbers in this part no longer correspond to those 
used in the NPRM. Much of the content of proposed part 143 has been 
removed or reordered, and several provisions have been changed to apply 
to new vessels only. The requirements

[[Page 40061]]

of proposed subpart C, deferred requirements for existing vessels, and 
proposed subpart D, for oil and hazardous material in bulk, have been 
divided among the other subparts. This derivation table lists part 143 
section numbers in this final rule and the corresponding part 143 
section from the NPRM:

------------------------------------------------------------------------

    In several provisions in the NPRM, we offered two different options 
for complying with design or operational standards in certain areas. 
These sections were divided up into ``functional requirements'' and 
``prescriptive options'' for complying with the functional 
requirements. The prescriptive options represented one way to comply 
with the functional requirements, but an owner or managing operator 
could choose another way to comply so long as the alternative method 
was approved by the OCMI or an approved third party. On further 
consideration, we have consolidated the functional requirements with 
other language about when and how exceptions from the baseline standard 
may be granted (see Sec.  143.210).
Changes to Subpart A, ``General''
    The applicability of the subparts within this part has changed. The 
specific changes are discussed elsewhere in this preamble, but we have 
revised the discussion of applicability in subpart A to provide an 
overview of the entire part for readers. Most notably, subpart A now 
specifies that existing vessels (which includes those vessels already 
under construction that do not meet our definition of ``new towing 
vessel''), have 2 years to comply with the rule; for certain listed 
provisions, the delay is longer. Additionally, because the structure of 
part 143 has changed, new vessels must comply with subparts B and C of 
part 143 except as noted in specific sections in subpart C instead of 
the proposed subpart E. Under our ``new towing vessel'' definition, no 
vessel would be subject to new vessel requirements until at least July 
20, 2017.
    Because of the additional discussion of the applicability of each 
subpart and the changes to the discussion of functional requirements 
with prescriptive options for compliance, we removed proposed Sec.  
143.110. The content specific to OCMI or third-party acceptance of 
alternative methods is relocated to Sec.  143.210 and consolidated. 
However, we will address here the comments received on proposed Sec.  
143.110. One commenter suggested adding the word ``company'' to the 
entities named in Sec.  143.110(c) on alternatives to the prescriptive 
option. The Coast Guard declines to make this change, because an 
``owner or managing operator'' may be a company. Another commenter 
suggested replacing OCMI or third-party acceptance with a TSMS accepted 
by the third party. This change would remove the option of OCMI 
acceptance and would not be appropriate for vessels not covered by a 
TSMS, so the Coast Guard declines to make the change.
    As previously discussed in this preamble, we relocated the 
definition of ``independent'' to part 143 in response to a comment 
pointing out that the definition was specific to vessel arrangements 
described in this part.
    Several commenters noted that that the phrase ``replacement in 
kind'' should not be construed too narrowly, so as to avoid subjecting 
existing towing vessels to unnecessary additional requirements. One 
commenter suggested that where a piece of equipment such as a generator 
is replaced with another that has the same function and similar 
characteristics but is not the exact same model, such replacement 
should be considered ``replacement in kind.'' Another commenter 
suggested that proposed Sec.  143.220 (now incorporated into Sec.  
143.205) would prevent vessels from upgrading to more efficient 
equipment.
    We added a definition of ``replacement in kind'' to Sec.  136.110 
in response to numerous comments requesting clarification of this term, 
which is used in parts 143 and 144. When equipment needs to be 
replaced, it may be replaced by the same or similar equipment, or it 
may be upgraded. It is certainly acceptable to upgrade, but an upgrade 
is not considered a replacement in kind because the maintenance and 
operation of the new equipment may require operator training, new 
maintenance schedules, OCMI approval of equipment arrangement, and an 
update to the vessel's TSMS.
    Finally, the Coast Guard removed the list of material incorporated 
by reference specifically for part 143 (proposed Sec.  143.120) and 
moved that content to a consolidated list for the entire subchapter at 
Sec.  136.112. The Coast Guard received one comment on the 
incorporation of standards by reference in part 143; the comment 
appeared to indicate that new incorporations are not necessary because 
there are existing, currently applicable standards elsewhere in title 
46. The standards incorporated in part 143 are necessary because towing 
vessels represent a unique class of vessel design, and other standards 
incorporated in various CFR sections are not currently applicable to 
towing vessels. The engineering standards incorporated in subchapters 
F, J, and Q, for instance, are generally applicable to much larger 
ships with different risk profiles, such as passenger ships or large 
tank vessels.
Changes to Subpart B, ``Requirements for All Towing Vessels''
    The organization of subpart B remains largely the same as in the 
NPRM, although the section numbers have changed. We removed proposed 
Sec.  143.230, ``Guards for exposed hazards,'' as it was duplicative of 
proposed Sec.  144.345. For more on this, see discussion of changes to 
part 144 below. We also added two sections from proposed subpart C--
pilothouse alerter

[[Page 40062]]

systems and towing machinery--which have delayed application dates for 
existing vessels. An existing vessel must comply not later than 5 years 
after the issuance of the first COI for the vessel. This delayed 
compliance date is reflected in Sec.  143.200(c) and is the same length 
of time as was proposed in the NPRM at proposed Sec.  143.320. The 
details of these requirements, and other changes to proposed subpart C, 
are discussed later in this preamble.
General
    We redesignated proposed Sec.  143.220 as Sec.  143.205. The Coast 
Guard received a suggestion that we insert the phrase ``in accordance 
with their responsibilities'' in proposed Sec.  143.220(b). The Coast 
Guard agrees with the general approach and has revised the paragraph to 
clarify that crewmembers must demonstrate ability to operate the 
machinery and electrical systems for which they are responsible.
    Another commenter suggested changing the requirements in proposed 
Sec.  143.220(c)(3) to apply to all control stations (operating 
stations) instead of just the primary one. The Coast Guard agrees and 
has removed the word ``primary'' from this requirement. The Coast Guard 
understands that certain vessels have more than one operating station; 
in such cases, each operating station would need to comply with revised 
and redesignated Sec.  143.205(c)(3).
    One commenter suggested that the Coast Guard insert the phrase 
``with respect to the installation in question'' in the sentence in 
proposed Sec.  143.220(d) that requires installations to comply with 
subpart C for new vessels if the installation is made after this rule 
becomes effective and is not a replacement in kind on an existing 
towing vessel. The Coast Guard declines to make that change because the 
original language was unambiguous and the addition unnecessary.
    Another commenter asked the Coast Guard to change proposed Sec.  
143.220 to ``clarify that replacements mandated by regulation will not 
trigger the referenced follow-on regulations . . . .'' The Coast Guard 
disagrees. If equipment requires replacement and the owner or managing 
operator chooses not to make a replacement in kind, it is considered an 
upgrade and subpart C may apply. Depending on the significance of the 
replacement (whole system versus one particular piece), newer standards 
may be applicable. Applying subpart C to replacement equipment will not 
result in the same cost as applying subpart C to existing equipment, 
and is appropriate because the maintenance and operation of the new 
equipment may differ.
Alternate Design
    We combined proposed Sec.  143.215 on alternate design 
considerations with the functional requirements provisions of proposed 
Sec.  143.110 that called for OCMI or third-party acceptance; these are 
now located in Sec.  143.210, and have been further condensed to refer 
to similar provisions in Sec.  136.115. As noted earlier in this 
preamble, these changes do not alter the availability of approval for 
alternate designs.
    The Coast Guard received several comments requesting that we add 
``company'' after ``owner'' in proposed Sec.  143.215. The Coast Guard 
partially agrees. In Sec.  143.210(a), we inserted ``or managing 
operator'' after ``owner'' to be consistent with other sections where 
we list both. The definition of ``managing operator'' in Sec.  136.110 
includes organizations, and if a company owns the vessel, it would be 
covered by the definition of ``owner.''
TSMS
    We removed proposed Sec.  143.205, as it was duplicative of part 
138. With respect to the content of that proposed section, one 
commenter had suggested the Coast Guard include ``guidelines'' in 
paragraph (a), along with policies and procedures to ensure compliance. 
The Coast Guard declines to make such a change in the provisions 
discussing TSMSs, because the purpose of the TSMS is to help ensure 
compliance with all parts of this subchapter, and the inclusion of 
guidelines is not necessary to that minimum standard. Nothing prohibits 
the inclusion of guidelines in individual TSMSs, however.
Existing Vessels Built to Class
    We redesignated proposed Sec.  143.210 as Sec.  143.215. Proposed 
Sec.  143.210 had provided that vessels classed by the American Bureau 
of Shipping (ABS), or built to ABS rules, would be considered in 
compliance with part 143 if they met certain additional requirements. 
However, we determined that the requirements for existing and new 
vessels need to be further distinguished.
    This final rule creates flexibility for existing vessels: Existing 
towing vessels currently classed by any recognized classification 
society, or determined compliant with any recognized classification 
society's appropriate rules, are equivalent to nearly all of the 
requirements of subpart B. We have reduced the list of additional 
requirements originally proposed in Sec.  143.210(b), so that existing 
vessels that are classed or built to class rules only need to meet the 
pilothouse alerter requirement (by the delayed effective date, 5 years 
after the issuance of the first COI for the vessel) and readiness and 
testing requirements. These fundamental safety provisions replace the 
longer list that we had proposed. In particular, proposed paragraph 
(b)(2) on potable water was removed because, as a number of commenters 
noted, proposed Sec.  143.225 was ``reserved'' and listed no 
requirements. The Coast Guard agrees with the suggestion to remove this 
reference to potable water requirements; we note that Food and Drug 
Administration requirements in 21 CFR 1250.82 already apply to potable 
water systems for most towing vessels engaged in interstate commerce. 
In addition, in Sec.  140.510(a)(14) an owner or managing operator must 
identify and mitigate health and safety hazards related to the towing 
vessel's potable water supply.
    Also, with regard to proposed Sec.  143.210(a), the Coast Guard 
received several comments suggesting we change the phrase ``mechanical 
standards'' to ``machinery standards.'' The Coast Guard agrees that 
``machinery standards'' is the industry accepted term, and amended the 
section accordingly. In what is now paragraph (b), the Coast Guard 
clarified that the OCMI or a third party would deem the vessel to be in 
compliance.
    As is discussed later in this preamble, new towing vessels meeting 
ABS rules in accordance with Sec.  143.515, or classed by ABS, are 
considered to be in compliance with part 143 except for the pilothouse 
alerter and readiness and testing sections that are described below. 
New towing vessels classed by other recognized classification societies 
may also be compliant with part 143 if approved by the Coast Guard. 
This final rule offers more flexibility than the proposed rule, in that 
it provides for Coast Guard approval of other class standards, but does 
not automatically accept all classed vessels as compliant with part 
143. In light of the wide range of possible class standards in the 
future, we believe this is the correct balance between safety and 
feasibility.
Machinery Space Fire Prevention
    We redesignated proposed Sec.  143.235 as Sec.  143.220. One 
commenter suggested the Coast Guard change ``flammable liquid'' to 
``flammable or combustible liquid'' in proposed paragraphs (a) and (c), 
to cover diesel fuel. The Coast Guard agrees that most grades of diesel 
fuel are considered ``combustible liquids'' as opposed to more volatile 
``flammable liquids'' such as gasoline, and amended the section 
accordingly to indicate the

[[Page 40063]]

intent of preventing fires. We also refer to 46 CFR subpart 30.10 for 
definitions of those terms. Similarly, one commenter suggested we add 
``and other flammable liquids'' to the restriction on oil in proposed 
paragraph (b). The Coast Guard agrees with the underlying concern, but 
has removed proposed paragraph (b) because it was duplicative of the 
fire hazards provision in part 142.
    With respect to proposed Sec.  143.235(c), several commenters said 
that the temperature threshold required, 65.5 [deg]C 
(150[emsp14][deg]F), is too low to be practical. The Coast Guard agrees 
that the temperature specified in the NPRM was impractical, and amended 
what is now Sec.  143.220(b) to adopt the SOLAS requirements for 
insulation of hot surfaces: 220 [deg]C (428[emsp14][deg]F) as was 
suggested by several commenters. SOLAS is an established, 
internationally recognized set of rules developed and ratified by 
maritime nations worldwide, and the Coast Guard determined that this 
was the most appropriate reference.
    With respect to proposed Sec.  143.235(d), one commenter suggested 
the Coast Guard change ``materials'' to ``products.'' The Coast Guard 
agrees that the suggested change is necessary to achieve uniformity 
between parts 142 and 143, and amended Sec.  143.220(c) accordingly. In 
the same section, one commenter suggested that the Coast Guard include 
the amounts of flammable and combustible materials that can be safely 
stored in machinery spaces under this section. The Coast Guard declines 
to do so because, under the original proposed language, the limits 
would be determined by the size of the designated areas defined in 
Sec.  142.225 or the size of the flammable storage cabinet that 
satisfies UL 1275. In addition, because available storage areas will be 
limited by prohibitions on ignition sources in those areas, we believe 
that operators will carry only the amounts of products necessary for 
the vessel mission.
    The Coast Guard received several comments recommending adding the 
language from proposed Sec.  144.360(c) to proposed Sec.  143.235, 
because it pertains to machinery space fire prevention. The Coast Guard 
declines to add the language to part 143 because the provisions of 
Sec.  144.605 address this topic for all towing vessels.
Control and Monitoring Requirements
    We redesignated proposed Sec.  143.240 as Sec.  143.225. The Coast 
Guard received several comments requesting that we change ``thrust'' to 
``RPMs'' in proposed paragraph (a).
    The Coast Guard does not agree with these comments because the use 
of the word ``thrust'' is intended to cover other propulsion systems in 
use today, including varying propulsion and steering control designs, 
as well as indicators. An example would be a shaft tachometer as an 
acceptable means of monitoring the vessel's propulsion thrust.
    The Coast Guard received several comments asking if the position of 
the rudder joystick is sufficient to meet the requirements of proposed 
paragraph (b). The position of the rudder joystick does not provide a 
positive position of the rudder and is not acceptable. The rudder 
joystick simply provides an indication of the commanded position of the 
rudder.
Alarms and Monitoring
    We redesignated proposed Sec.  143.245 as Sec.  143.230. The Coast 
Guard received several comments suggesting that the panel in the 
wheelhouse needs only to alarm and should not be required to identify 
the piece of equipment that has tripped the alarm. The Coast Guard 
agrees that specifying the exact piece of equipment that is in an alarm 
condition is not necessary in the wheelhouse. Rather, a summary alarm 
in the wheelhouse is considered sufficient. We amended Sec.  143.230 
accordingly. The Coast Guard also received comments concerning the 
intent of requiring alarms to function when primary power is lost. We 
agree that it is impractical that alarms on existing vessels have a 
backup source of power in addition to the primary power supply, because 
the primary concern on a loss of main electrical power is restoring the 
main power source.
    The Coast Guard received several comments requesting whether 
certain alarms should signal high or low levels; the Coast Guard agrees 
that clarification is needed, and amended the section to specify which 
alarm settings are based on high or low conditions. Several commenters 
suggested that the requirement for a ``main engine fuel oil pressure'' 
alarm should be removed. One commenter indicated that requiring fuel 
oil pressure alarms was unnecessarily rigorous and would have a 
disproportionate effect on small businesses. We agree that a wide range 
of diesel engine fuel pressures may be acceptable depending on the 
manufacturer, and that fuel oil pressure is not normally considered a 
mandatory parameter to be monitored; these levels may be checked each 
watch. We therefore removed proposed Sec.  143.245(a)(3) and (6) when 
drafting the final version of Sec.  143.230.
    One commenter requested a high level alarm requirement on day 
tanks, stating that a number of spills have occurred as the result of 
day tanks being overfilled. The Coast Guard agrees that a high level 
alarm could be beneficial. However, we do not have spill data to 
justify such a requirement and there are other acceptable means to 
ensure the day tank is not overfilled (for example, routing the 
overfill line to a storage tank, physically observing the level of the 
tank during filling operations, monitoring quantity of fuel transferred 
so it does not exceed available capacity). In the future, we may 
propose requiring this alarm if spill data suggests overfilling of the 
day tank could have been avoided by such an alarm.
    The Coast Guard also received several comments stating that 
proposed Sec.  143.245(a)(9) (now designated Sec.  143.230(a)(6)) 
addressing low fuel level alarms repeats proposed Sec.  143.275(d) and 
that one of the two sections should be removed. The Coast Guard agrees, 
and removed proposed Sec.  143.275(d).
    One commenter suggested removing the requirement for hydraulic 
level alarms.
    The Coast Guard disagrees. There is a need to monitor the hydraulic 
fluid in the steering hydraulic tank in the event of leaks or pipe/hose 
rupture, because it is essential for maneuvering.
    With respect to proposed Sec.  143.245(b)(3), the Coast Guard 
received several comments in favor of a self-monitoring alarm system.
    The Coast Guard agrees that a self-monitoring alarm system is a 
practical alternative to manual testing of the alarm system, and 
amended Sec.  143.230(b)(2) accordingly.
    The Coast Guard received several comments suggesting deletion of 
the requirement at proposed Sec.  143.245(c) that gauges be visible at 
the operating station. The Coast Guard agrees that gauges are not 
required at the operating station, provided that there are alarms or a 
summary of alarms at each operating station. We amended this section 
for clarification.
    One commenter suggested that several provisions of the NPRM, 
including gauges for engines at proposed Sec.  143.245(c), should not 
be required because they are not required of passenger vessels in 
subchapter T.
    The Coast Guard disagrees with the suggestion that that no gauges 
should be provided, although we agree that subchapter T vessels and 
subchapter M vessels could have similar systems. The gauges required by 
proposed Sec.  143.245(c) are considered minimum requirements for 
monitoring engine

[[Page 40064]]

performance. However, in the final rule, the number of gauges required 
has been reduced to only those considered essential to engine 
monitoring, and which normally are provided by the manufacturer with 
all engine installations regardless of the vessel type.
    With respect to paragraphs (c)(1) and (3) one commenter suggested 
that the Coast Guard add the engine RPMs to these sections. The Coast 
Guard agrees that the main engine(s) and auxiliary generator engines 
should be equipped with RPM indicators, and amended the sections 
accordingly.
    We deleted proposed paragraph (d) because summary alarms are 
already allowed under revised Sec.  143.230(b)(1), so there is no need 
for a separate section allowing this on excepted vessels. With respect 
to proposed paragraph (d) one commenter suggested that the Coast Guard 
add ``crewmembers responding to the alarm(s).'' The Coast Guard agrees 
with the comment in that the proposed text could have been more 
specific regarding communications between crewmembers. However, 
proposed paragraph (d) was applicable only to excepted vessels, and 
given the traditional size and service of excepted vessels, we 
ultimately determined that a separate paragraph was not necessary.
General Alarms
    We redesignated proposed Sec.  143.250 as Sec.  143.235. One 
commenter suggested that the Coast Guard clarify the applicability of 
this section. That commenter also recommended requiring the public 
address system on towing vessels be equipped with ``talk-back'' 
capability.
    The Coast Guard has modified the applicability section to be 
clearer, and has made similar clarifying changes to Sec.  143.240(a). 
As for adding a requirement for ``talk-back'' capability, we disagree. 
This capability is not required on any commercial vessel and would be 
unnecessary for the usual purposes of a public address system.
Readiness and Testing
    We redesignated proposed Sec.  143.260 as Sec.  143.245 and, as 
described earlier in this preamble, removed the functional and 
prescriptive designators in favor of a unified section on alternatives 
at the beginning of the part. One commenter suggested that the Coast 
Guard remove ``(if available)'' from proposed Sec.  143.260(a).
    The Coast Guard agrees that manufacturer's instructions are 
normally available, and removed the phrase ``if available.''
    With respect to proposed Sec.  143.260(b), the Coast Guard received 
several comments to amend parts of the table to clarify that the intent 
is for a crew change and not a watch or shift change. The Coast Guard 
agrees that testing the propulsion and steering controls is not 
necessary with every shift change, and amended the section to clarify 
that the test is only necessary prior to getting underway, but not more 
often than once every 24 hours. In the same section, one commenter 
suggested changing the required testing frequency of alarm setpoints 
and pressure safety valves from annually to every 2 years or longer.
    The Coast Guard agrees and has amended Table 143.245(b) to make 
these requirements more consistent with similar requirements in 
subchapter F. Finally, one commenter suggested the Coast Guard change 
``pressure vessel safety valves'' to ``pressure vessel relief valves.'' 
The Coast Guard agrees that relief valve is the more common terminology 
and amended the section accordingly.
System Isolation and Markings
    We have redesignated proposed Sec.  143.270 as Sec.  143.250. The 
Coast Guard received a number of comments suggesting that ``graywater 
lines need not be fitted with isolation valves or marked if all piping 
is contained inside a fuel tank or void.'' The Coast Guard disagrees. 
It is not possible for ``all piping'' to be contained in a tank, and it 
is important for the piping system to be identified. However, the 
intent of the requirement is for crew members to be able to identify 
piping systems used in normal, everyday operations, and therefore it is 
not essential that systems in normally inaccessible spaces be 
identified.
    One commenter suggested that the Coast Guard add a new paragraph 
(e) to proposed Sec.  143.270 to cover sanitary discharges, and add 
``Except as provided in paragraph (e) of this section'' to the 
beginning of this section. The Coast Guard declines to do so because 
the requirements in this section would apply to any system piping 
penetrating the hull beneath the waterline. However, variations could 
be accommodated through the provision for alternate design approvals 
that has already been discussed in this preamble.
    With regard to proposed Sec.  143.270(e), one commenter stated that 
the use of ``either'' ISO Standard 14276 or marking in accordance with 
the TSMS applicable to the vessel would lead to a lack of uniformity 
between towing vessels and is counterproductive. The Coast Guard agrees 
that one standard for industry color-coding of piping is preferred, but 
lacks the casualty data to support a mandate for one particular 
standard. Another commenter suggested that the Coast Guard identify the 
basic colors used to mark piping.
    The Coast Guard declines to do so because the international 
standard referenced in this section already identifies basic piping 
colors.
Fuel System Requirements
    We redesignated proposed Sec.  143.275 as Sec.  143.255. The Coast 
Guard received several comments suggesting that the requirement at 
proposed Sec.  143.275(c) to replace fuel filters be based more on 
``performance requirements'' as opposed to manufacturer 
recommendations. The Coast Guard partially agrees and amended the 
section, but considers manufacturer recommendations to be based already 
in part on performance requirements, such as differential pressure and 
time in service. We also amended proposed Sec.  143.275(a) to clarify 
that the term ``be maintained'' used in the proposed rule means a 
documented maintenance plan. We also made nonsubstantive changes to 
proposed Sec.  143.275(b) for brevity and clarity.
    As previously discussed, we removed proposed Sec.  143.275(d) in 
response to comments stating it was duplicative of proposed Sec.  
143.240(a)(9). We then added a new paragraph (d) that requires the use 
of diesel fuel unless approval for another fuel is obtained pursuant to 
Sec.  143.210 or Sec.  143.520. We did this because diesel fuel is 
considered the standard for marine fuels, and the use of more volatile 
fuels such as liquefied natural gas or propane requires approval by the 
MSC.
Fuel Shutoff Requirements
    We redesignated proposed Sec.  143.280 as Sec.  143.260. The Coast 
Guard received a comment suggesting that we define ``near the source of 
supply'' as used in proposed Sec.  143.280(c). The Coast Guard agrees 
with this commenter. To clarify the section, we drafted Sec.  
143.260(c) to require that the valve be installed in the fuel piping 
directly outside of the fuel oil supply tank. We also received a 
comment suggesting that the use of extra heavy piping should be 
explicitly allowed as an alternative to situating the valve near the 
source.
    The Coast Guard disagrees. While such arrangements may be 
acceptable with proper piping materials or other design choices, 
locating the valve directly after the fuel supply source is the most 
effective way to stop a leak.
    The Coast Guard received one comment suggesting that we remove the 
words ``outside the space where the

[[Page 40065]]

valve is installed'' from proposed Sec.  143.280(d) and instead 
specifically require that the valve be located on the weather deck.
    The Coast Guard disagrees because a safe place outside the 
machinery may not always be located on the weather deck.
    The Coast Guard also received one comment stating, in part, that 
the ``requirement for remote shutdown of each engine outside the 
machinery space is unworkable'' and suggesting the requirement should 
be removed.
    The Coast Guard does not agree: The remote shutdown outside the 
machinery space is necessary in the event that the engine space is not 
accessible due to fire.
Additional Fuel System Requirements for Towing Vessels Built After 
January 18, 2000
    We redesignated proposed Sec.  143.285 as Sec.  143.265. With 
respect to proposed Sec.  143.285(b), the Coast Guard received several 
comments requesting clarification on the proposed regulations regarding 
``portable bilge pumps.'' A ``portable bilge pump'' as specified in 
paragraph (b) is a dewatering pump. We received a comment suggesting 
that the proposed rule would limit an operator's ability to dewater a 
damaged tow. We disagree. The regulation allows for proper stowage and 
use of portable tanks or cans for portable bilge pumps. The rules for 
the barge itself are beyond the scope of this rulemaking, but 
``portability'' of fuel is allowed in the circumstances specified by 
this section. If an operator is safely able to reach a towed unit, 
there is no prohibition on using portable equipment to dewater or fight 
a fire on that unit.
    The Coast Guard received a comment suggesting that the proposed 
regulations did not consider a ``closed loop'' ventilation system 
option for venting. The Coast Guard does not agree with this 
characterization of the proposed rule, because proposed Sec.  
142.285(c)(1), now designated Sec.  143.265(c), allows tank vents to be 
combined, as long as there is ultimately a vent to the outside. We 
received a comment suggesting revisions to the required size of the 
vent piping. We partially agree, and the paragraph (c) has been amended 
for clarity on this issue.
    One commenter expressed concern with the use of flexible fuel 
lines, noting that the use of flexible hose in the industry was 
``rampant,'' and also suggested requiring containment systems beneath 
oil purification equipment. This rule allows for flexible hose that 
meets certain incorporated standards, meaning the hose has passed 
pressure and fire testing. The rule also addresses the containment 
concern by requiring that gaskets and seals be maintained, and bilges 
kept free of accumulated oil.
Bilge Pumps or Other Dewatering Capability
    We redesignated proposed Sec.  143.295 as Sec.  143.275. The Coast 
Guard received several comments suggesting ``prescriptive'' 
regulations, such as those for larger ships in 46 CFR 56.50, be applied 
to proposed Sec.  143.295. The Coast Guard decided not to impose a 
prescriptive requirement for bilge pumping systems in this regulation 
because of the extremely large number of different configurations 
possible for towing vessels. A commenter said that proposed Sec.  
143.295 was not specific enough with regard to dewatering capability, 
noting that potentially ineffective dewatering methods such as 
``buckets'' could be acceptable under the proposed text. We agree and 
have amended the section to emphasize that an installed or portable 
bilge pump must be available.
    One commenter suggested that only ``installed'' (not portable) 
bilge piping should be required to have a check/foot valve to prevent 
unintended flooding. The Coast Guard agrees because a permanently 
installed, power-operated bilge pump is not the equivalent of a 
portable pump. We amended the text accordingly, as the use of a 
portable pump implies constant operator monitoring, which would 
normally prevent improper flow (backflooding).
Pressure Vessels on Existing Vessels
    With respect to proposed Sec.  143.300, the Coast Guard received 
several comments suggesting the application of existing pressure vessel 
requirements in 46 CFR subchapter F and the ASME Code. Although these 
are certainly acceptable for pressure vessel installations on all 
vessels, the Coast Guard does not have casualty data to support the 
mandatory use of the rigorous requirements of subchapter F by existing 
towing vessels. Similarly, one commenter suggested the incorporation of 
the ASME Code Section IV for heating boilers. The Coast Guard agrees 
that the ASME Code is a preferable design standard for heating boilers, 
and considers it acceptable for power or heating boilers on any vessel. 
However, the Coast Guard has no significant reportable casualty data 
with a root cause of boiler or pressure vessel design that justifies 
the increased cost of requiring all towing vessels to use the ASME Code 
for towing vessel boilers.
    The Coast Guard received several comments suggesting that proposed 
Sec.  143.300(b) be clarified with regard to examination requirements. 
The Coast Guard agrees and amended paragraph (b) so that pressure 
vessels are externally examined annually, along with relief valve 
testing twice every 5 years. These changes make inspection requirements 
for pressure vessels and relief valves more consistent with the 
inspection requirements in subchapter F for pressure vessels on larger 
ships. Because of these changes we added a new paragraph (c) to require 
the maximum allowable working pressure be indicated on all pressure 
vessels.
    The Coast Guard received a question concerning the pressure vessel 
requirements of proposed Sec. Sec.  143.300 and 143.540: ``Could a 
towing vessel also meet the requirements of 46 CFR 61.10 in lieu of the 
ABS Rules as prescribed in 143.540?'' The Coast Guard agrees that 
compliance with 46 CFR 61.10 is acceptable and equivalent to (or 
exceeds) the requirements in this rule. However, Sec.  61.10 generally 
is applicable to large ships and the Coast Guard does not require 
towing vessels to meet subchapter F engineering requirements.
Electrical Systems
    We redesignated proposed Sec.  143.305 as Sec.  143.400. The Coast 
Guard received several comments suggesting the Coast Guard remove the 
requirement at proposed Sec.  143.305(d) that switchboards and 
distribution panels be labeled with a description of the loads they 
serve. The Coast Guard partially disagrees. For proper circuit 
identification during operations and maintenance, labels must be 
provided for the equipment served. However, the Coast Guard has removed 
the requirement that equipment be marked with the location of the 
isolating switch of circuit breaker, because the panel should indicate 
that information.
    The Coast Guard received several comments on proposed Sec.  
143.305(i) expressing confusion on the use of male receptacle outlets 
when transmitting power between two receptacles. The requested changes 
were in line with the Coast Guard's original intent, but we decided the 
clearest revision would be to remove the provision about male outlets. 
As long as the plugs, cables, and receptacles are compatible and 
designed for the power to be transmitted, specifying a particular 
configuration is not necessary.
Shipboard Lighting
    We redesignated proposed Sec.  143.310 as Sec.  143.410. One 
commenter argued

[[Page 40066]]

that the requirement for emergency lighting in proposed Sec.  143.310 
would be prohibitively expensive for small businesses and is neither 
necessary nor of any value on smaller towing vessels where the crew 
typically knows the vessel intimately.
    The Coast Guard disagrees. With respect to the cost, there are 
three different options for compliance, some as inexpensive as 
phosphorescent lighting strips. With respect to the utility this 
requirement in Sec.  143.410 for internal crew working and living 
areas, we consider this lighting essential--even on smaller vessels--to 
facilitate egress in emergency situations when normal lighting is not 
working and dense smoke may be present.
    The Coast Guard received several comments asking whether berthing 
spaces were required to have emergency lighting under proposed Sec.  
143.310(a). Specific berthing spaces are not required to have emergency 
lights. However, in the event of power loss there must be sufficient 
illumination in living areas to enable personnel egress from the living 
space. One commenter suggested adding a requirement for one flashlight 
per bunk. The suggestion is a good practice for mariners but the Coast 
Guard declines to make it mandatory.
    With respect to proposed Sec.  143.310(b)(2), the Coast Guard 
received several comments suggesting we lower the required automatic 
battery-operated emergency lighting capability from 3 hours to 30 
minutes. The Coast Guard partially agrees with these comments, and has 
modified the requirement in Sec.  143.410(b)(1) to 2 hours, consistent 
with subchapter T. The requirement of 2 hours will ensure the 
availability of battery-powered lights when needed, along with ample 
battery capacity. Emergencies that require egress from a space, such as 
a living space, do not necessarily mean abandoning the vessel: The crew 
may need to assemble on deck to fight a fire or flooding, or restart 
the main electrical plant. We confirmed that, for the second option, 
phosphorescent strips are available that provide illumination for more 
than 2 hours.
    In addition, the Coast Guard removed proposed Sec.  143.310(b)(1) 
because it was redundant with a related subparagraph in proposed Sec.  
143.340(b)(9).
Pilothouse Alerter System
    The pilothouse alerter requirements are now located in Sec.  
143.450. In the NPRM, we proposed a pilothouse alerter system 
requirement for all vessels (see proposed Sec.  143.210, as well as 
Sec. Sec.  143.325, 143.515, and 143.520), with a deferred compliance 
date for existing vessels. We proposed this requirement in response to 
the NTSB report on the Robert Y Love allision with the I-40 Bridge, as 
well as eight incidents where the operator died while navigating the 
vessel and other cases that indicated probable incapacitation of the 
operator. The Coast Guard received comments supporting and opposing the 
inclusion of the deferred requirements proposed in Sec.  143.325.
    After considering public comments, as well as the traditional 
service and limited manning of towing vessels 65 feet or less in 
length, we determined that a pilothouse alerter system is not necessary 
for towing vessels 65 feet or less and have eliminated the alerter 
requirement for this category of vessels. This is accomplished in Sec.  
143.450(e).
    We received a comment suggesting the alerter could become a 
distraction for harbor assist vessels. We disagree, because a compliant 
system could be set up to reset, for instance, each time the throttle 
or steering was changed. We also received comments that the alerter 
should not be required when a vessel had overnight accommodations but 
those accommodations were not in use. We decline to make a regulatory 
exception for this scenario, but this subchapter allows the OCMI the 
discretion to waive certain requirements on a case-by-case basis when 
appropriate.
    We received a comment suggesting that requirements for systems such 
as pilothouse alerters should be performance-based, and flexible with 
regard to rapid developments in technology. The Coast Guard agrees. We 
have not specified a particular design for an alerter system, only that 
such system must meet certain performance requirements with regard to 
time limits and adjustability of the alarm time to suit the vessel 
mission.
    With respect to proposed Sec.  143.325(a)(3), imposing a 10-minute 
maximum acknowledgment time for the alerter, the Coast Guard received 
several comments suggesting that the acknowledgment time for the 
pilothouse alerted should be less than 10 minutes. The Coast Guard 
partially agrees. New paragraph (b) of Sec.  143.450 provides that the 
time may be reduced by the owner or managing operator in the TSMS but 
must not be in excess of 10 minutes. We received a comment suggesting 
that the Robert Y Love incident would not have been prevented by an 
alerter set at 10 minutes. We acknowledge that it is possible that an 
alerter set at 10 minutes may not have prevented the incident. It is 
also possible that an operator could become incapacitated at any time 
within a 10-minute alerter reset period. In the Robert Y Love incident, 
had the pilot become incapacitated 1 minute before the alarm was 
scheduled to sound, it is possible another crew member could have made 
it to the pilothouse and averted the allision. As a reference point, we 
note that SOLAS requirements for larger vessels (MSC.128(75)) require a 
bridge watchstander alarm with an elapsed time between resets of 3-12 
minutes.
    We received a comment stating that ``fans with paper streamers 
effectively fool motion detector systems.'' The Coast Guard notes that 
a motion detector-type system is but one of many options to comply with 
the alerter requirement. An attempt to interfere with any system 
installed to meet the requirements of Sec.  143.450 would be 
investigated. And as stated in Sec.  140.1000, there are statutory 
penalties for violating the provisions of this subchapter.
    The Coast Guard received several comments suggesting that a second, 
adequately rested crewmember should be required in the pilothouse at 
all times, as well as comments suggesting a second crewmember is an 
unnecessary expense. The Coast Guard partially agrees with both 
comments. A second adequately rested crewmember in the pilothouse of a 
towing vessel, while not required by this section, is an acceptable 
alternative to the pilothouse alerter system as stated in Sec.  
143.450(d). We chose not to require that a second crewmember be in the 
pilothouse because, in light of the thousands of vessels of all sizes 
that safely operate with a single crew member on the bridge or 
operating station, depending on maneuvering circumstances, we could not 
justify the significant cost of requiring an additional watchstander on 
all towing vessels. However, under 46 U.S.C. 8104 and 46 CFR 15.705, it 
remains the master's responsibility to provide an adequate watch.
    The Coast Guard received a comment requesting clarification of the 
pilothouse alerter requirements for vessels with more than one 
operating station. Because the alerter is required to detect 
incapacitation of the vessel pilot, the system must be arranged to 
alarm at each operating station. There may be various system 
configurations that meet the intent of this requirement.
Towing Machinery
    The towing machinery requirements are now located at Sec.  143.460 
and apply to all vessels, with a deferred compliance date for existing 
vessels. In connection with proposed Sec.  143.330(b) the Coast Guard 
received several comments requesting an example of an

[[Page 40067]]

acceptable safeguard against the towing machinery becoming disabled if 
the tow gets out of line. The Coast Guard agrees, and added an example 
of a common safeguard to this section. We also received a comment 
suggesting that the ``winch slippage alarm'' sound in the pilothouse. 
The Coast Guard agrees such an alarm would be beneficial to operations, 
but we do not have the casualty data to support the mandate of such a 
system.
Deferred Requirements for Existing Vessels (Proposed Subpart C)
    As discussed earlier in this preamble, we removed proposed subpart 
C. We relocated to subpart B the requirements for pilothouse alerter 
systems and towing machinery, and retained the deferred compliance date 
for existing vessels: These requirements are discussed earlier in this 
preamble. We removed proposed Sec.  143.335 on remote shutdowns because 
a similar effect is accomplished through proposed Sec.  143.280 (now 
Sec.  143.260) on fuel oil shutoff, and because remote fuel shutoff is 
already required by 46 CFR subchapter C.
    The remaining deferred provisions of proposed subpart C--Sec. Sec.  
143.340 through 143.360 on specific electrical arrangements for 
existing towing vessels--have been moved to subpart C for new vessels. 
They do not apply to existing vessels. We made this change in response 
to comments indicating these provisions were not appropriate for 
existing vessels. Specifically, the Coast Guard received many comments 
recommending the deletion of the prescriptive requirements in proposed 
Sec. Sec.  143.340 through 143.360. Commenters characterized the 
proposed requirements as burdensome, costly, requiring extensive 
modifications, and not justified by risk.
    The Coast Guard does not agree that the proposed requirements were 
unjustified. Part 143 was developed in response to the recommendations 
in Sections 6.1 and 6.2 of the ABSG Consulting report, which were based 
on the risk analysis results in Section 4.3 of the report. See 
Uninspected Towing Vessel Industry Analysis Project Final Report, 
issued August 2006 and prepared by ABSG Consulting Inc., and Section 
III.C of the NPRM (76 FR 49978). An industry analysis project team 
performed a detailed analysis of the towing industry data from a number 
of data sources, such as MISLE and site visits. The team also used 
industry data provided by AWO as part of the Coast Guard-AWO Safety 
Partnership. Two previous examinations of towing vessel accident 
studies were also considered: The TSAC Towing Vessel Inspection Working 
Group report (TSAC 2005) and a report by the Coast Guard Allision 
Working Group (BAWG 2003). These risk analyses support characterizing 
the proposed requirements as risk-based.
    However, several comments asserted that the functional requirements 
in proposed subpart B, ``Requirements for All Towing Vessels,'' are 
sufficient for all existing towing vessels. These commenters 
recommended the removal of proposed subpart C, ``Deferred Requirements 
for Existing Towing Vessels.'' Further, the Coast Guard believes that 
many existing towing vessels were originally built to acceptable 
national or marine standards. Those would already be in substantial 
compliance with many of the requirements of subpart B of part 143 of 
the final rule.
    The machinery and electrical requirements in subpart B will provide 
the owners or managing operators of existing towing vessels with the 
standards that existing equipment and installations must meet or should 
have met during the construction of towing vessels. Third-party 
inspections and eventual certification of electrical and machinery 
systems of existing towing vessels that are in marginal condition or 
poorly maintained may require some upgrades but may not necessarily 
need extensive modifications of the vessel's systems. Commenters 
provided estimates of the cost of extensive retrofits to existing 
vessels in the range of $75,000 to $300,000 per vessel, considerably 
higher than the cost estimated in the NPRM Regulatory Analysis ($5,000 
to $20,000 per individual requirement). Further, comments indicated 
that the need for retrofits to comply with the regulatory requirements 
in proposed Sec. Sec.  143.340-143.360 would impact more than the 
generally less than 5 percent of vessels per requirement estimated in 
the NPRM Regulatory Analysis. The net result in total costs could 
exceed $300 million (10-year, undiscounted). For these reasons, the 
requirements in proposed Sec. Sec.  143.340-143.360 that were proposed 
to apply to all towing vessels will now apply only to newly built 
towing vessels, which includes vessels undergoing a major conversion. 
Comments pertaining to the substance of those standards are discussed 
later in this preamble.
Requirements for Oil or Hazardous Material in Bulk (Proposed Subpart D)
    The proposed rule included deferred requirements for vessels that 
tow oil or hazardous material in bulk. In response to comments 
indicating these provisions were not appropriate for existing vessels, 
we removed these requirements from existing vessels and relocated the 
provisions to subpart C on new towing vessels. Comments pertaining to 
the substance of those standards are discussed later in this preamble.
Subpart C, ``Requirements for New Towing Vessels''
    Because of the organizational changes discussed earlier in this 
preamble, proposed subpart E for new towing vessels is now designated 
subpart C. We revised the applicability section in line with the 
organizational changes described in our discussion of subpart A, and 
made nonsubstantive editorial changes. We also removed proposed Sec.  
143.505, as its content is now covered by the applicability section at 
Sec.  143.500. In Sec.  143.510, we replaced the phrase ``plan 
approval'' with the more accurate language ``verification of compliance 
with design standards.'' We removed Sec.  143.530 as unnecessary in 
light of other revisions to the part.
    The ``classification option'' has changed little between the NPRM 
and the final rule. For a new towing vessel, the same three options 
apply in the final rule as in the proposed rule: New vessels may be 
built to recognized classification society standards (Sec.  143.515); 
to ABYC standards (Sec.  143.520) for smaller towing vessels; or to 
neither standard, but instead be subject to the requirements set out in 
subparts B and C of part 143. As an alternative to complying with the 
electrical system requirements that are now listed in subpart C, the 
vessel may instead comply with certain ABS rules as set out in Sec.  
143.580; this alternative is substantively the same as was proposed in 
the NPRM.
    As was the case in proposed Sec.  143.515, even vessels built to 
ABS rules or classed by ABS must comply with specific provisions of 
part 143. In this final rule, those provisions are the requirements for 
vessels that move tank barges carrying oil or hazardous material in 
bulk (Sec. Sec.  143.585 through 143.595), the readiness and testing 
requirements of Sec.  143.245, and the pilothouse alerter requirements 
of Sec.  143.450. The readiness and testing requirements of Sec.  
143.245 help verify proper in-service operation and safety of main and 
emergency systems, above and beyond the initial design requirements of 
part 143. As discussed above, the proposed potable water requirements 
have been removed, but they remain a health and safety requirement 
under Sec.  140.510(a)(14). Also, in this final rule we created 
flexibility by providing for approval of towing vessels built to

[[Page 40068]]

recognized classification society rules other than ABS's.
    Section 143.520(a) remains substantially as proposed, but paragraph 
(b) has been revised to remove several requirements. New towing vessels 
of 65 feet or less in length that are built to the ABYC standards 
listed in paragraph (a) need only comply with the readiness and testing 
requirements of Sec.  143.245, and with the requirements for vessels 
that move tank barges carrying oil or hazardous material in bulk 
(Sec. Sec.  143.585 through 143.595) if applicable. Other requirements 
have been removed for these vessels, including the pilothouse alerter 
requirements.
Pressure Vessels on New Vessels
    We redesignated Sec.  143.540 as Sec.  143.545. With respect to 
proposed Sec.  143.540(b), the Coast Guard received several comments 
requesting alternate standards to the ABS rule referenced for pressure 
vessels. While the ABS rules referenced are an industry standard for 
pressure vessels, the Coast Guard may determine other design standards, 
such as the ASME Boiler and Pressure Vessel Code, to be equivalent as 
described in Sec.  143.210. Therefore, we made no changes to this 
paragraph in response to this comment.
Electrical Engineering Systems
    Several comments also recommended the proposed prescriptive 
requirements in proposed Sec. Sec.  143.340-143.360 should not apply to 
new towing vessels. The Coast Guard does not agree. The proposed 
requirements of these sections are based on the present acceptable 
national or marine electrical engineering standards. As explained in 
Section IV of the preamble to the proposed rule, the Coast Guard 
developed part 143 after considering the reports provided by ABSG 
Consulting and TSAC, which were generated from marine casualty cases 
and risks. Also, as stated in the preamble to the proposed rule, the 
Coast Guard conducted its own in-depth analysis of the cases reviewed 
for the ABSG report, along with deficiency reports from examinations of 
towing vessels during compliance exams conducted pursuant to 33 CFR 
part 104 as part of the implementation of the Maritime Transportation 
Security Act of 2002 (MTSA) (46 U.S.C. Chapter 701). These reports 
provided evidence that substandard machinery installation and 
maintenance is a concern on towing vessels. For example, from January 
2006 through August 2008, the Coast Guard conducted 768 of these MTSA 
compliance examinations of towing vessels and issued 2,949 
deficiencies. Electrical deficiencies involving installation and 
maintenance accounted for 8 percent (226) of the deficiencies. This 8 
percent deficiency rate highlights the need to establish more specific 
standards for electrical installations on towing vessels. The current 
regulations in subchapter C for electrical installations on uninspected 
vessels are minimal and not adequate for towing vessels. In addition, 
the incremental cost to incorporate the new standards into the design 
and construction of a new vessel are low in comparison of the total 
construction costs of the vessel and the potential reduction in risk of 
fire.
    Several commenters provided cost estimates to retrofit an existing 
vessel to comply with the proposed requirements in Sec. Sec.  143.340-
143.360 that range from $75,000 to $300,000. These estimates are higher 
than the cost estimated by Coast Guard in the NPRM Regulatory Analysis 
(which ranged from $5,000 to $20,000 per requirement ($60,000 per 
vessel if all of the requirements are incurred). The comments also 
indicated that far more vessels would require the retrofits than was 
estimated in the NPRM Regulatory Analysis. The NPRM estimated 
annualized costs of part 143 at $3.2 million and the benefits at $5.7 
million. If the high end of the costs per vessel of $300,000 were used, 
the annualized costs could as much as triple. Increasing the affected 
population for the retrofits as per the comment would increase the 
costs even more. Given the new information on the potential range of 
costs and affected population, the Coast Guard has determined that the 
benefits of the NPRM's proposed deferred requirements for existing 
vessels will not outweigh the costs. Given the potential cost burden of 
retrofitting existing vessels, the baseline electrical requirements for 
existing towing vessels in the final rule, coupled with a robust 
inspection regime, will establish an adequate safety environment for 
towing vessels.
    The electrical requirements in this final rule will provide the 
owners or managing operators the design and engineering standards for 
equipment and installations for new construction. The prescribed 
electrical power and distribution system designs are based on proven 
electrical recommendations, practices, and consensus-based standards.
Electrical Power Sources, Generators, and Motors
    We redesignated proposed Sec.  143.340 as Sec.  143.555, and made 
nonsubstantive changes to simplify and shorten the section. The Coast 
Guard received several comments suggesting that proposed Sec.  143.340 
be clarified so that a backup generator could be used as a secondary 
power source. The Coast Guard agrees, and amended the text in paragraph 
(a)(3) to better explain the requirements for backup power source.
    We also received a comment suggesting the proposed Sec.  143.340 
may be interpreted as requiring duplicate essential systems such as 
radar or emergency lighting. We did not intend the original language to 
be read that way, and have amended the corresponding section of the 
final rule to clarify that emergency communications and navigation 
equipment must be provided with a backup power source.
    We received a comment stating that the electrical load analysis 
requirements of proposed Sec.  143.340 were ``excessive and 
unnecessary''. Although the Coast Guard believes that a load analysis 
is required for nearly all vessels with generators, we presume that 
load analysis has already been done for existing vessels and is 
therefore applicable only to new towing vessels. This change is 
reflected in this final rule. We also simplified the analysis 
requirement by removing proposed paragraph (b)(2).
    The Coast Guard received several comments suggesting we include the 
specific NEC reference in article 430 in this section. The Coast Guard 
agrees and amended the section by specifying that Parts I through VII 
of article 430 are required. These Parts of Article 430 further define 
the scope of motor overcurrent protections required. We also received 
comments suggesting that the proposed requirements in Sec.  143.340 
will require ``complete rewiring'' of inland towing vessels. This 
comment is addressed by our decision to apply these requirements only 
to new vessels.
    The Coast Guard received several comments suggesting we lower the 
ambient temperature rating at paragraph (b)(7) of this section from 50 
[deg]C to 40 [deg]C, similar to ABS rules. The Coast Guard partially 
agrees. The Coast Guard amended the section so that the generator does 
not need to be certified to operate in an ambient temperature of 50 
[deg]C if it can be shown that the space the generator is in does not 
exceed 40 [deg]C. This reduction in minimum ambient temperature rating 
reflects an established normal ambient temperature allowance, even for 
large vessels currently regulated by the Coast Guard.
    With respect to proposed Sec.  143.340(b)(9) (now designated Sec.  
143.555(b)(8)) the Coast Guard received several comments suggesting 
clarification on what the Coast Guard meant by ``two independent 
sources of

[[Page 40069]]

electricity'' in this section. To clarify, the prescriptive requirement 
in what is now paragraph (b)(8) requires a minimum of two sources of 
power. For example, if a generator provides the normal source of power 
for navigation lights, there must be another generator or a battery 
bank arranged as a secondary power source. One commenter suggested 
adding the word ``essential'' to paragraph (b)(8) this section. The 
Coast Guard agrees, and has modified the text accordingly. We have also 
amended the section to specify the radios and navigation equipment 
required in Sec. Sec.  140.715 and 140.725. This change is in line with 
other comments suggesting that we include the distress alerting 
communications equipment listed in Sec. Sec.  140.715 and 140.725. 
These comments also suggested that the backup power source for the 
distress alerting communication equipment have a means of monitoring 
the voltage available, and the source of supply selected either by an 
automatic switchover or a simple switch in the vicinity of the 
emergency distress alerting communications equipment. The Coast Guard 
agrees that distress alerting equipment should be added to this 
section, and also that a means must be provided to monitor the battery 
condition, and amended the section accordingly.
    We received a comment suggesting that, if a battery were to serve 
as the required secondary power source, it would need to be 
unnecessarily oversized for the loads specified. We mostly disagree; 
there is no requirement that the secondary power source be a battery 
(e.g., the secondary source could be a generator). The electrical loads 
specified in this section are not necessarily large consumers, and any 
battery sized for these loads needs to be sized proportionally, not 
oversized. Also, this requirement in proposed Sec.  143.340 has been 
amended to apply only to new towing vessels.
    However, we agree with the commenter that some alarms may not 
require a secondary power source, and have amended this section to be 
specific as to which alarms require secondary power.
    We received comments suggesting removal of the requirement in 
proposed Sec.  143.350 to separate overcurrent protection for essential 
and non-essential systems. We disagree, because the intention is to 
prevent opening the circuit on essential loads because of a fault in a 
non-essential system. This requirement has been amended to apply only 
to new towing vessels.
    We received a comment suggesting that ``essential systems'' be 
defined to avoid confusion in the inspection process. The Coast Guard 
agrees, and notes that a proposed definition of essential system was 
included in proposed Sec.  136.110. However, we have amended the 
requirements of Sec.  143.555 of the final rule to provide clarity on 
this issue.
Electrical Grounding and Ground Detection
    We redesignated Sec.  143.355 as Sec.  143.570. With regard to 
proposed Sec.  143.355 the Coast Guard received several comments 
stating that most towing vessels are ungrounded, and that the section 
should specifically adopt the ground detection requirements of 46 CFR 
183.378. Proposed Sec.  143.355 did not prohibit the use of ungrounded 
systems. The Coast Guard recognizes that towing vessels can have either 
grounded or ungrounded electrical distribution systems. We agree with 
the comment, however, and therefore added detection requirements 
similar to 46 CFR 183.378. This requirement applies only to new towing 
vessels, and the requirements are based on vessels regulated under 
subchapter T, which have similar electrical systems. While revising 
this section, we modified paragraph (e) to consolidate paragraphs 
(e)(1) and (3).
    The Coast Guard also received several comments stating that this 
section does not allow the use of common two-prong appliances less than 
50 volts or two-prong double-insulated tools. The Coast Guard considers 
the use of two-prong double-insulated tools to be an acceptable 
industry practice, and amended the section to allow the use of double-
insulated tools, or two-prong appliances of less than 50 volts.
Electrical Conductors, Connections, and Equipment
    We redesignated proposed Sec.  143.360 as Sec.  143.575. As 
discussed elsewhere in this preamble, we received comments stating that 
existing vessel compliance with this section and other electrical 
sections in the NPRM would involve substantial costs and retrofitting. 
The bulk of these comments are addressed by making these electrical 
requirements applicable only to new vessels.
    With respect to proposed Sec.  143.360, the Coast Guard received 
several comments suggesting we clarify paragraph (a)(2) with respect to 
overhead wiring. The Coast Guard agrees, and amended the section to 
specify that this requirement is applicable to overhead and vertical 
cable runs supported by cable hangers.
    We received a comment suggesting the use of a performance standard 
rather than a specific cable hanging method. The Coast Guard partially 
agrees with the concern, but could not find an acceptable performance 
standard, so we have amended the section to allow a 48-inch spacing, 
rather than the proposed 24 inches, to be consistent with recognized 
electrical-contracting standards.
    In paragraph (a)(3) of that section, one commenter suggested that 
wiring be allowed within 24 inches of moving machinery if the wiring is 
protected. The Coast Guard agrees, and amended this section to be 
applicable to cable and wire runs. We also clarified that cable and 
wire runs within 24 inches of moving machinery must be adequately 
protected to prevent damage, and added text to clarify what ``moveable 
machinery'' means.
    In paragraph (b), one commenter suggested replacing the phrase 
``may not'' with ``must not''; the Coast Guard agrees that this 
language is clearer. This requirement is consistent with the permitted 
use of flexible cords or extension cords in Section 400.7 of the 
National Electrical Code (NEC), and Section 24.6.1 of IEEE 45-2002.
    In paragraph (c), the Coast Guard received several comments stating 
that this section prohibits the use of power strips. The intent of this 
section is not to prohibit the use of multi-outlet adapters (power 
strips), but to prevent ``daisy-chaining'' of power strips, which may 
overload the circuit. We have amended this section to clarify the 
requirement to prevent circuit overload when using power strips.
Towing Vessels That Tow Oil or Hazardous Material in Bulk
    Because of the reorganization discussed earlier, a separate subpart 
for towing vessels that tow oil or hazardous material is no longer 
required. Proposed Sec. Sec.  143.405 through 143.435 have been 
incorporated into the final rule's subpart C for new vessels. The 
requirements of proposed subpart D will not apply to existing towing 
vessels. This change responds to many comments arguing that proposed 
subpart D should not apply to existing vessels.
    Commenters who opposed the application of proposed subpart D to 
existing vessels argued that the proposed requirements were not based 
on risk; would require unjustified or wholesale retrofitting; would 
cause severe economic penalty, disproportionate financial hardship for 
small towing companies, and might eliminate certain classes of towing 
vessels. Also, several comments asserted

[[Page 40070]]

that the Coast Guard ignored the decline in the frequency and amount of 
oil spills from tank barges over the last twenty years. Other comments 
mentioned that the proposed requirements in subpart D will have little 
impact on the prevention of oil spills in the tank barge sector 
because, as noted by TSAC, ``Current industry best practices have 
produced a dramatic reduction in oil spills from tank barges over the 
last decade and a half, with a record low 919 gallons spilled (out of 
nearly 65 billion gallons transported) in 2010, the last year for which 
complete Coast Guard statistics are available.'' Also, industry 
comments mentioned that the preamble cites S. 1892, a bill introduced 
into the 110th Congress, as a reason for including the proposed subpart 
D in part 143, and note that this bill never became law.
    We proposed subpart D based on the statistics from the ABSG report, 
which included high and low consequence incidents. Given the casualty 
history presented in the ABSG report, the Coast Guard determined that 
the proposed requirements could reduce the ongoing risk of oil spills 
and the resulting consequences. Data on oil spills through 2014 shows a 
continual pattern of a few major spills contributing to the majority of 
the volume spilled each year. Even though a recent TSAC report notes a 
dramatic reduction in oil spills from tank barges over the last decade 
and a half, the casualty data through 2014 indicates that minimum 
safety standards for engineering system design, coupled with a robust 
inspection regime, would maintain or even further reduce the risk of 
spills.
    Several commenters provided information on the cost to retrofit 
existing vessels to comply with the Subpart D requirements. The 
estimates range for all of the deferred requirements from $75,000 to 
$300,000 per vessel, higher than the Coast Guard estimates in the NPRM 
Regulatory Analysis. Existing vessels are already designed and 
constructed, so requiring a complete replacement of some vital 
engineering systems is neither practical nor justified by the safety 
benefit achieved.
    In light of the new information on the costs for retrofitting 
existing vessels, the requirements of the proposed Sec. Sec.  143.340 
through 143.435 have been removed for existing vessels. The 
requirements are retained in the final rule for new towing vessels, as 
there is a smaller incremental cost to incorporate the design features 
in a new vessel.
    Several commenters misinterpreted the proposed requirements in 
proposed Sec. Sec.  143.405, 143.410, and 143.420 (now Sec. Sec.  
143.585, 143.590, and 143.595) regarding the installation of a second 
main engine. The intention of the proposed rule was to require 
redundancy of necessary auxiliaries, allowing a sustained or restored 
propulsion capability of the towing vessel--not to require redundant 
engines. The proposed requirements did not prohibit a towing vessel 
with single propulsor, but only placed requirements for support 
equipment (auxiliaries) on vessels with one propulsor. The requirements 
differentiate between independent and/or redundant control systems and 
the propulsion systems under remote control. For example, on a vessel 
with two propulsion engines, the proposed rule requires the remote 
control of one engine to be independent of the remote control of the 
other engine. For risk reduction, the proposed requirements would 
ensure that when one engine remote control fails, remote control of the 
other engine would remain operable. We have also modified what is now 
Sec.  143.595 for vessels with one propulsor, to clarify which 
equipment is considered a vital auxiliary, and eliminated the 
requirement that this equipment ``automatically'' assume the function 
of the failed unit. Although it is acceptable for vessels to have 
equipment that automatically starts when other equipment fails, it is 
not absolutely necessary, and in fact it may be preferred for crew 
members to visually assess a failure or impending failure of the 
primary equipment before deciding to manually start the redundant 
equipment.
    In proposed Sec.  143.405 (now Sec.  143.585), one commenter 
suggested preventative maintenance schedules and additional required 
training in lieu of some of the requirements in this section. The Coast 
Guard disagrees. While an attentive operator may notice problems before 
the associated alarms and redundancy requirements are triggered, the 
alarms (with appropriate delays) are required as a means to alert the 
operator. We received a comment suggesting separation of the propulsion 
and steering requirements in this section. The Coast Guard acknowledges 
that propulsion and steering are two separate and vital systems, but 
the requirements for alternate arrangements and independence for these 
systems as specified apply to both propulsion and steering. Additional 
propulsion requirements are also specified in Sec. Sec.  143.590 and 
143.595.
    We also received a comment suggesting the use of a ``bow steering 
module,'' which is essentially an assist vessel attached to a barge 
propelled by a traditional towboat. Although the Coast Guard agrees 
that a bow steering module may be considered equivalent to the 
requirements of an alternate means of propulsion and/or steering, this 
type of arrangement would need to be determined in particular cases by 
the OCMI or the Commandant for equivalency.
    With respect to proposed Sec.  143.405 (now Sec.  143.585), one 
commenter asked whether paragraph (k) requires automatic starting of a 
standby generator or if the loads referenced should be on battery 
backup. The Coast Guard agrees that the proposed section was unclear 
and amended the section by specifying a second source of supply that is 
capable of automatically starting, and of helping to restore or 
maintain power to propulsion, steering and related controls when the 
main power source fails. This requirement will provide continued or 
restored operation of a towing vessel that moves tank barges carrying 
oil and hazardous material in bulk, even if the primary systems fail. 
One commenter was confused about what the Coast Guard meant by ``stored 
energy'' in paragraph (l). The Coast Guard clarified this section by 
providing examples of ``stored energy systems'' that are generally used 
onboard towing vessels. We also simplified this section by removing 
paragraph (l)(2) as not necessary for towing vessels.
    With respect to proposed Sec.  143.420 (now Sec.  143.595), we 
added a clarifying description of ``vital auxiliaries'' in paragraph 
(a).
    One commenter asked if proposed paragraph (d)(2) required two 
hydraulic tanks for steering. In response to the commenter, an 
acceptable arrangement would consist of two independent hydraulic 
tanks, or one hydraulic tank separated by a solid baffle, which is 
considered equivalent to two tanks. However, the Coast Guard has 
determined that the steering system requirements of Sec.  143.550 are 
sufficient, that the requirements of Sec.  143.595 are intended only 
for vital auxiliaries for propulsion, and so we have eliminated the 
steering system paragraphs from this section. Also, the fuel system 
requirements of proposed Sec.  143.420(c) were redundant to current 
Sec.  143.265, so we removed that paragraph.
    We received a comment suggesting elimination of proposed 
redundancies in systems for vessels towing oil or hazardous material, 
and leaving those types of decisions for a case by case determination 
in the vessel's TSMS. We disagree, because it is important for vessels 
with one propulsor to have redundancies in the vital auxiliaries--such 
as fuel, lube oil, and cooling

[[Page 40071]]

water--supporting the engine. However, this section has been amended to 
apply only to new towing vessels.
    We received a comment suggesting ``grandfathering'' proposed 
deferred requirements because of prohibitive costs, and have addressed 
this comment by applying these requirements to new vessels only. 
Another commenter requested clarification of ``independent'' as opposed 
to ``redundant.'' Those terms have distinct meanings, but we agree that 
the proposed text could be clearer, and have amended Sec. Sec.  
143.115, 143.590, and 143.595 to define and use the term 
``independent.'' In this subpart, ``independent'' means the ability to 
perform a function regardless of the status of another system, and 
``redundant'' is not used in subchapter M.

N. Construction and Arrangement (Part 144)

    We received general comments suggesting the requirements proposed 
in part 144 were not justified by risk-based decisions and should 
therefore be removed. A commenter felt that some proposed regulations 
in this part are too stringent: For example, the commenter felt that 
the stability requirements in subparts A, B, and C of part 144 are not 
reflective of the loss history for inland vessels.
    We disagree with the characterization of proposed part 144 as not 
risk-based and, further, we believe they represent the minimum safety 
standard of construction and arrangement that is common to all 
inspected vessels. While there are some requirements applicable only to 
new towing vessels, these requirements do not exceed the requirements 
imposed on other types of small inspected vessels and, for this reason, 
we do not agree that they can be considered to be too stringent. As for 
existing towing vessels, we find no requirements in this rule that 
would require costly modifications to a properly maintained and 
satisfactorily functioning existing towing vessel.
    Three commenters suggested that organizing vessels into two 
subparts, existing vessels and new vessels, instead of three subparts, 
would be easier for issues related to grandfathering. We generally 
agree that the proposed regulations would benefit from reorganization, 
and we have modified this part to delete requirements repeated in other 
parts of the subchapter or that were too vague. Further, we agree with 
the commenters with respect to organizing requirements into a format 
that is more aligned with other inspection subchapters.
    A majority of the requirements are either the same or very similar 
to requirements contained in the Construction and Arrangement part in 
subchapter T, Small Passenger Vessels (46 CFR part 177). We aligned 
part 144 with the organization, and subpart and section titles, of part 
177. This organizational choice also better reflects the relatively 
large number of part 144 requirements that apply to both existing and 
new vessels, and the relatively small number that apply to new vessels 
only. As a result of these changes, we use the term ``vessel'' when 
discussing requirements that apply to both new and existing vessels, 
and use the specific terms ``new'' or ``existing'' vessel to describe 
those that apply only to one or the other. At the end of this 
discussion of comments on part 144 and structures and stability, we 
have provided a derivation table that lists part 144 section numbers in 
this final rule and the proposed sections from which they derived. 
Also, where appropriate, we have noted the corresponding part 177 
section number or an explanation of an edit.
    We received several comments, mainly from maritime companies 
suggesting revisions to Sec.  144.215. Commenters suggested that 
special consideration be given to structural requirements for towing 
vessels ``operating exclusively within [limited geographic areas], and 
towing vessels under 65 feet in length, in addition to towing vessels 
of an unusual design.''
    We agree with these commenters that the types of vessels for which 
special consideration may be given in proposed Sec.  144.215 should be 
clarified, and we have adopted the suggested under-65-feet-in-length 
measure to define what we had described as ``small vessels'' in the 
proposed rule. This rule also provides that special consideration may 
be given to vessels operating exclusively within a limited geographic 
area, because the OCMI is familiar with the specific hazards of the 
limited geographic areas within his or zone.
    Commenters felt that proposed Sec.  144.220(a) should be edited to 
ensure that routine upgrades to equipment, such as engine repowering, 
would not require compliance verification. Further, towing companies 
felt that proposed Sec.  144.220(a) and (b) should be revised to 
clarify the intention of the terms ``major conversion or alteration'' 
and ``replacements in kind.''
    The Coast Guard believes that compliance verification with design 
standards for upgrades to equipment, such as engine repowering, as in 
proposed Sec.  144.220(a), should be retained because of possible 
changes to stability and other vessel characteristics related directly 
to safety. We have done so in this final rule in our redesignated 
verification of compliance section, Sec.  144.135.
    With respect to the request to clarify the terms ``major conversion 
or alteration'' and ``replacement in kind'' in proposed Sec.  
144.220(a) and (b), in Sec.  136.110 we have clarified our proposed 
definition of ``major conversion'' and added a definition of 
``replacement in kind.'' We note that Sec.  144.135 uses the phrase 
``major conversion or alteration'': Although ``alteration'' is not 
defined in this rule, we use the term as it currently used in 46 CFR 
91.55-10 to mean an alteration that involves the safety of the vessel. 
Separately, we have reformatted the text of Sec.  144.135 in tabular 
form to make this section easier to read.
    The term ``verification of compliance'' in part 144 addresses 
verifying that the design of a vessel meets the standards used. To 
distinguish this activity from the compliance verification required in 
part 137 under the TSMS option, we have added the words ``with design 
standards'' to this term. We also removed from this section the 
provision that a verification of compliance be performed upon request 
of the Coast Guard because this is covered by part 136.
    To provide more options for the qualifications in proposed Sec.  
144.225, now re-designated Sec.  144.140, we have extended the group of 
entities able to verify compliance with design standards to include the 
Coast Guard and certain authorized classification societies, not just 
ABS. For the purposes of this verification, the authorized 
classification society must have been delegated the authority to issue 
a SOLAS Cargo Ship Safety Construction Certificate and the employee who 
performs the verification must have the proper qualifications. Similar 
references to ABS with respect to a verification of compliance with 
design standards have been revised accordingly. Regardless of the 
inspection option chosen, the verification of compliance with design 
standards can be performed by any one of the persons or entities 
identified in Sec.  144.140.
    Some commenters discussed the costs of developing plans for review. 
Two maritime companies suggested that proposed Sec.  144.230, 
Procedures for verification of compliance with construction and 
arrangement standards, would be costly for companies with older vessels 
that were constructed without plans produced by a naval architect. A 
maritime company suggested alternatives for hull structure

[[Page 40072]]

and piping, electrical, machinery systems and stability reviews that it 
viewed as more cost-effective.
    Proposed Sec.  144.230, now re-designated Sec.  144.145, was 
intended for vessels undergoing a major conversion or alteration to the 
hull, machinery, or equipment--as described in proposed Sec.  144.135. 
A major conversion often results in an extension of the vessel's 
service life. Therefore, the procedures in Sec.  144.145, would not be 
invoked unless required by Sec.  144.135. Because Sec.  144.135 does 
not require a verification of compliance with design standards for an 
existing vessel, we do not envision that an owner or operator would 
need to provide plans to ensure the existing vessel complies with the 
standards used. A new towing vessel will need to undergo a verification 
of compliance with design standards.
    We have clarified procedures for verification of compliance with 
design standards to require copies of verified plans be provided to the 
third-party organization that conducts a survey, if applicable, in 
addition to the OCMI.
    Two commenters suggested that because naval architects are well 
qualified, a P.E.'s signature is not needed for vessel construction. 
While many naval architects are also licensed P.E.s in the jurisdiction 
in which they reside or conduct their business, not all are. The 
benefits of P.E. licensure are well documented and accepted in the 
United States. The requirement for a P.E.'s seal on vessel construction 
plans may be considered commensurate with that required for buildings 
within a municipality. Accordingly, we clarified in Sec.  144.145 that 
the documents must be stamped with the seal authorized for use by the 
individual performing the verification, whether that is the P.E. or a 
representative of the recognized classification society or the Coast 
Guard. We acknowledge that there may be gaps in documentation of 
smaller vessels, so we have clarified that the term ``plan'' means 
drawings, calculations, schematics, diagrams or other documents and 
provide a list of what those plans may include, based mostly on 46 CFR 
177.202.
    We have clarified and revised the provisions for sister vessels in 
proposed Sec.  144.235, now re-designated Sec.  144.155, to be 
consistent with Sec. Sec.  144.135, 144.140, and 144.145.
    Two commenters said that the marking requirements in proposed Sec.  
144.240 should include the same basic colors used to mark piping for 
flammable liquid, seawater cooling, and firefighting systems proposed 
in Sec.  143.270(c). We do not agree that piping marking requirements 
in part 143 need to be repeated in part 144. We made no changes from 
the proposed rule based on these comments.
    Both proposed Sec.  144.310(a) for existing vessels and proposed 
Sec.  144.405 for new vessels specified that a vessel classed by ABS 
would meet the structural standards of part 144, because ABS rules 
include stability standards that generally meet those contained in 
Coast Guard regulations. We have consolidated those sections into Sec.  
144.120, stating that a vessel that is classed by a recognized 
classification society is in compliance with subparts B and C of part 
144. In accordance with proposed Sec.  136.210(c), as well as similar 
changes in this rule, we have acknowledged that structural and 
stability standards contained in the rules of other recognized 
classification societies are commensurate with ABS rules, and have 
extended this provision to class by a recognized classification

    In a similar way, we recognized that proposed Sec.  136.210(d) 
deemed a vessel with a valid load line certificate to be in compliance 
with structural and stability standards, among others, and since 
proposed Sec.  144.310(b) repeated this, Sec.  144.125 contains this 
text.
    In proposed Sec. Sec.  144.305 and 144.310, we proposed structural 
standards for an existing vessel. These are now contained in Sec.  
144.200, which has been aligned with Sec. Sec.  144.120 and 144.125 to 
avoid repetition. As provided in proposed Sec.  144.305(a), an existing 
vessel to which no construction standard was applicable would need only 
show that it has been in satisfactory service and its service history 
does not cause the structure of the vessel to be questioned. Similarly, 
structural standards for new vessels that we proposed in Sec.  144.410 
are now contained in Sec.  144.205. The use of alternate design 
standards is covered by Sec.  136.115 as discussed elsewhere in this 
preamble.
    Because the requirements of proposed Sec. Sec.  142.220(c) and 
144.350(a) were so similar, we have merged them into Sec.  144.415.
    A commenter said that proposed Sec.  144.315 and Sec.  144.415 
regarding stability standards would not apply to all vessels and was 
concerned about grandfathering a number of vessels that may be unstable 
and remain uninspected. As discussed in more detail elsewhere in this 
preamble, this final rule focuses on the towing vessels presenting the 
greatest risk. Further, several commenters stated that stability is not 
a problem on inland towing vessels. The Coast Guard notes that casualty 
records generally support this view. For an existing vessel that will 
be inspected, the stability standards for an existing vessel in Sec.  
144.300 will require the vessel to show it has a history of 
satisfactory service that does not cause its stability to be 
questioned, or meet a similar standard that ensures adequate stability. 
Stability standards for a new vessel in Sec.  144.305 will require the 
vessel to show it complies with minimum standards that are applied to 
other inspected vessels. One commenter suggested that a minimum 
freeboard of ``like 24 inches'' for all vessels would improve stability 
standards. While the Coast Guard agrees that a requirement for such a 
freeboard may improve stability, both the degree of the stability 
improvement and its benefit are unknown and, for this reason, a 
freeboard requirement of this amount was not included in this final 
rule.
    An association commented that that the proposed regulation (Sec.  
144.355) does not contain size requirements and specifications for 
accommodation spaces for the crew. The commenter recommended several 
specifications to be included in the regulations.
    The Coast Guard declines to adopt the suggested specifications. Our 
proposed requirements for accommodation spaces for the crew on towing 
vessels subject to inspection under this subchapter were contained in 
proposed Sec.  144.355 and were generally taken from subchapter T--
small passenger vessels. In response to comments, we have amended 
proposed part 144 to include a subpart dedicated to crew spaces. Crew 
space requirements in this final rule, as we proposed in the NPRM, are 
based on performance standards rather than prescriptive size 
requirements.
    With respect to proposed storm rail requirements in proposed Sec.  
144.340, now re-designated Sec.  144.810, we added the option of hand 
grabs but removed the requirement for storm rails on both sides of a 
passageway more than 6 feet wide because there are no towing vessels to 
which this subchapter would apply that would have such a wide 
passageway.
    An individual suggested the removal of proposed Sec.  144.345, 
Guards in dangerous places, because of its similarity to proposed Sec.  
143.230. We decided to keep this requirement, now designated Sec.  
144.820, in part 144 and delete the similar requirement in part 143.
    With respect to insulation of hot piping, we retain the requirement 
for existing vessels in proposed Sec.  144.350(b), now redesignated 
Sec.  144.830, and for new vessels we provide a similar but more 
specific requirement that aligns with an existing requirement in 46 CFR 
177.970.

    In reference to a collision event involving the tug Caribbean Sea 
and a ``Duck'' tour boat in Philadelphia in 2010, a commenter 
recommended that the NPRM include ``height of eye'' guidelines for 
towing vessels. The commenter also suggested that the Coast Guard 
consider including the ``transmissivity of light'' through glazing 
materials on towing vessels in proposed Sec.  144.325 or Sec.  144.425.
    The Coast Guard notes that while ``height of eye'' requirements are 
not specifically addressed in this rule, the regulations in subpart I 
require windows and other openings at the operating station to be 
properly located to provide a clear field of vision. As proposed in 
both Sec. Sec.  144.325 and 144.425, the visibility of the windows 
immediately forward of the operating station in the pilothouse must 
allow for adequate visibility regardless of weather conditions. In 
response to the idea to include a ``transmissivity of light'' 
requirement, the Coast Guard notes that 46 CFR 177.1030(b) includes 
such a standard for operating station visibility for small passenger 
vessels and we decided to include this same requirement at what is now 
Sec.  144.905(e).

                                            for a new vessel is based on

                                            In practice, this change is
                                            a nonsubstantive

O. Miscellaneous Comments

    In the NPRM we discussed comments submitted in response to seven 
questions we posed in a December 30, 2004, Inspection of Towing Vessels 
notice. Some commenters commented on those questions and that 
discussion. One person stated that uninspected towing vessels have been 
running efficiently for more than a century and that they have no 
problems that need to be addressed by a TSMS. In response to a 
discussion of grandfathering, another commenter stated that many 
existing towing vessels have operated in excess of 40 to 60 years 
without a major accident.
    While towing vessels may be running efficiently, and many may not 
be involved in a major casualty, as we noted in the NPRM, towing vessel 
casualties continue to occur. Each year,\6\ there is an average of 18 
fatalities, 35 injuries, $66 million in property damages, and 446,000 
gallons of oil spilled. Additional damages occur after towing vessel 
casualties in the form of delays from lock and waterway closures. A 
primary objective of this rulemaking is to reduce fatalities, injuries, 
property damaged, and oil spilled, by reducing the risk of towing 
vessel casualties.
---------------------------------------------------------------------------

    \6\ Casualty consequences are from MISLE for accidents from 
2002-2007.
---------------------------------------------------------------------------

    Others who commented on our discussion of these questions from 2004 
focused on specific subject areas intended to be addressed by our 
proposed regulatory text and the reasoning we provided in the preamble 
of the NPRM for that proposed text:
     Machinery and Electrical: A commenter noted that space 
constraints and crew abilities should be considered before requiring 
new equipment on small vessels.
     Applicability: Three commenters suggested that existing 
vessels should be ``grandfathered'' to minimize the expense and 
potential closing of businesses that will not be able to comply with 
new regulations. One commenter felt that few vessels other than those 
under 26 feet, or those used for commercial recreational vessel towing 
assistance, should be exempted from the regulation, and that fleeters 
should be exempted on a case-by-case basis.
     Construction & Arrangement, Fire Protection, and TSMS: One 
of those commenters would only apply grandfathering to equipment, hull 
construction and structural fire-protection requirements, but 
recommended that all vessels should comply with the proposed SMS rules 
within one year.
     TSMS: The same commenter suggested that using the ISM Code 
from 2002 as a guideline in developing the SMS requirements will allow 
for a number of operators using the AWO RCP to be compliant.
     Fire Protection: The commenter also felt that existing 
vessels should be treated differently from newly constructed vessels 
because of the likelihood that fire standards will make it difficult to 
retrofit existing vessels.
    While these comments are not in direct response to the regulatory 
text we proposed, we have addressed these comments in the same section 
of the preamble where we discuss comments on the corresponding proposed 
regulatory text. For example, for a response to the comment regarding 
whether existing and new vessels should be treated differently 
(``grandfathered'') with respect to fire protection standards, see the 
Fire Protection discussion of comments section.
    A towing company requested that the Coast Guard consider issuing a 
supplemental NPRM so the public and industry will be able to review the 
revisions to the rule before it is final. A maritime company suggested 
that the Coast Guard urge towing companies to become familiar with 
tried and tested engineering guides and standards. The commenter also 
suggested that the Bridging Program remain functioning until all towing 
vessels are found to be compliant with the rule.
    We disagree with this commenter about issuing a supplemental NPRM. 
This final rule reflects consideration of the thousands of comments we 
received on the NPRM we published in 2011.
    Regarding urging towing companies to become familiar with tried and 
tested engineering guides and standards, we encourage towing companies 
to obtain knowledge from such guides and standards, but the purpose of 
this final rule is to establish specific requirements. This rule 
provides some flexibility (e.g., the option to choose a

[[Page 40075]]

TSMS or Coast Guard inspection regime) but it is not a guidance 
document: it imposes requirements for which penalties may be applied if 
the requirements are not met. We have not made changes from the 
proposed rule based on this comment.
    As for the Bridging Program, we are currently in Phase 2 of that 
program. During Phase 1, we conducted Industry Initiated Examinations 
for companies taking advantage of the opportunity to participate in 
this Coast Guard program. Phase 2 is focused on Risk-Based Targeted 
Examinations and is scheduled to continue until this final rule becomes 
effective. Phase 3 will commence with the implementation of the new 
subchapter M towing vessel inspection regulations and issuance of 
Certificates of Inspection (COIs).
    A commenter suggested that towing vessel officers and officer 
candidates be tested on the new towing vessel inspections that appear 
in the final rule. The commenter said the Coast Guard provides only one 
opportunity to test the ``professional knowledge'' of candidates for 
Apprentice Mate/Steersman, Mate/Pilot, and Master of Towing Vessels, 
and that for years, it tolerated insufficient knowledge of existing 
regulations throughout the towing industry by licensed officers, 
management, and even Coast Guard personnel assigned to boarding 
parties. He noted that the Coast Guard's Towing Vessel ``Bridging'' 
program has done a commendable job trying to reverse this trend.
    Before imposing training requirements on those credentialed under 
46 CFR subchapter B, we would want to receive comments in a separate 
rulemaking on such proposed requirements. As for Coast Guard personnel 
conducting inspections under subchapter M, it is our normal process to 
draft a specific Performance Qualification Standard to ensure that 
inspectors are properly trained and fully capable of performing such 
inspections. Also in our oversight of TPOs, we will be sure to assess 
the TPO personnel's comprehension of subchapter M requirements.
    One commenter felt that there is a lack of adequately trained 
lookouts and that providing the Master and Pilot with a trained, well-
rested lookout can avoid many significant and costly towing accidents.
    We agree that a trained, well-rested lookout would be more likely 
to help avoid towing accidents than a tired lookout who is not 
adequately trained. The rule does not contain specific training or 
hours of work requirements for lookouts, although such training and 
fatigue management may be part of a TSMS. We are considering developing 
a separate rulemaking for hours of service and crew endurance 
management based on our authority under 46 U.S.C. 8904(c). If we do so, 
we will publish a separate document in the Federal Register. We have 
made no changes from the proposed rule based on these comments.
    Two commenters urged the Coast Guard to include a regulation that 
requires companies to provide mariners with a ``letter of sea service'' 
when the mariner is renewing their credentials.
    We believe this suggestion is outside the scope of this rulemaking. 
We would want to receive comments on this suggestion in a separate 
rulemaking before imposing such a requirement.
    An individual and an association felt that the ``Bridging'' book, 
updated with regulations from this final rule and other related 
regulations, should be provided in electronic format to provide a clear 
regulatory and policy statement to the towing industry and thereafter 
the Coast Guard should require the book or an updated electronic copy 
be carried aboard each towing vessel. One of these commenters noted 
that when the Coast Guard promulgated new oil pollution regulations in 
1973, they provided an explanatory pamphlet and a required completion 
of an ''open-book'' test on the new regulations.
    The Coast Guard notes that the Coast Guard's Bridging Program will 
cease to be applicable to towing vessels once this final rule becomes 
effective. We have prepared a Small Entities Guide which is available 
in the docket. With respect to an electronic form of subchapter M and 
other related regulations, we note that this final rule and subchapter 
M regulations that will become part of the CFR will be available 
through www.gpo.gov/fdsys.
    An association commented on the need for vessel route restrictions 
on a COI to be done on a vessel-by-vessel basis based upon reasonable 
safety considerations, and the need for adequate sea anchors and ground 
tackle for towing vessels that service oceans and coastwise routes.
    A Coast Guard OCMI will make vessel-specific determinations 
regarding a vessel's route and other operating conditions which will be 
identified in the vessel's COI. Towing vessels come in a variety of 
shapes, sizes, and services, some of which could utilize anchors and 
other ground tackle as appropriate. An anchor that is appropriate for 
the towing vessel would not necessarily be adequate to accommodate the 
tow. It is incumbent upon the towing vessel owner or managing operator 
to examine their operating conditions and decide if having an anchor 
and other ground tackle is appropriate.
    Two commenters suggested that doubler plating is not acceptable as 
a longstanding repair policy and recommended that the use of doubler 
plating be prohibited in regulation for vessels that have been 
inspected, unless it is approved by a Commandant.
    The Coast Guard has not adopted this recommendation. Second, since 
this comment was submitted, ASTM has issued a national consensus 
standard for the use of doubler plates as a permanent repair for 
vessels in all services. We have made no changes from the proposed rule 
based on these comments.
    A commenter suggested that the NFPA standards referenced in the 
NPRM be updated to the current editions. This commenter also requested 
that we correct our references to NFPA 70, the National Electrical Code 
(NEC), which are listed incorrectly as ``National Electric Code'' in 
proposed Sec. Sec.  136.110, 136.112, 143.120; 143.340(b)(6); 
143.350(b); and Section II, Abbreviations.
    The Coast Guard believes it is not necessary to update to the 
current editions of the NFPA standards at this time; in this final rule 
we have maintained the NFPA editions that we proposed in our NPRM. We 
have, however, corrected the error in our citations to NFPA 70, 
National Electrical Code (NEC).
    A maritime company felt that the terminology used in the proposed 
rule is broad and could be interpreted differently depending on the 
reader. The commenter gave ``major defects'' and ``substantial'' as 
examples of items totally left up to the opinion of the individual 
auditor, and suggested that more precise terms be included to ensure 
consistency in the application of the regulations.
    The Coast Guard notes that we did not use the term ``major 
defects'' in the NPRM. We did, however, use the term ``major non-
conformity,'' which we also defined. We also note that we have added or 
amended definitions based on many comments on our proposed rule.
    In this final rule we do use the word ``substantial,'' or a version 
of it, in our definition of ``major conversion'' in Sec.  136.110 and 
in our revocation of TPO approval section, Sec.  139.150. We agree that 
using more precise terms is appropriate when one is available, but 
sometimes a more flexible term is the only appropriate term to use. We 
believe this is true of our uses of the term ``substantial'' in this 
final rule and that the common understanding and

[[Page 40076]]

definition of that term, combined with Coast Guard interpretation of 
that term in other regulations, does place restrictions on how 
individual auditors may interpret it. We have made no changes from the 
proposed rule based on this comment.
    Lastly, a commenter suggested that the Coast Guard implement a 
notification system to remind vessel owners of deadlines that are 
approaching for their fleets.
    The Coast Guard notes that it has a system that is currently used 
for other inspected vessels to provide owner and managing operators 
with notification of impending compliance deadlines and plans to use 
this same system for towing vessels inspected under this subchapter. 
However, owners and managing operators are still ultimately responsible 
for meeting these deadlines and the associated inspection requirements 
including notification of the cognizant OCMI as required in part 136.

P. Crew Endurance Management Systems (CEMS)

    We thank those who commented in response to our Hours of Service 
(HOS) and CEMS preamble discussion in the NPRM (76 FR 49991-49997, Aug. 
11, 2011). These comments have helped to inform our consideration of 
HOS and CEMS issues confronting the maritime community.
    As we stated in the NPRM, the Coast Guard would later request 
public comment on specific hours-of-service or crew-endurance-
management regulatory text if it seeks to implement such requirements. 
We are considering developing a separate rulemaking for HOS and CEM 
based on our authority under 46 U.S.C. 8904(c). If we do so, we will 
publish a separate document in the Federal Register.
    We have summarized HOS and CEM comments below as a means of sharing 
the valuable input we received on this topic we discussed in the NPRM, 
but we have limited our responses because we are not proposing HOS or 
CEM requirements in this document. In general, we have only responded 
to these comments when we want to refer to what we said in the NPRM or 
point to currently available guidance or resources to address an issue 
raised. We have attempted to sort these comment summaries based on the 
questions we asked in the NPRM.
    Some commenters wondered why, despite assembling sufficient data, 
the Coast Guard seeks additional information on potential requirements 
to increase uninterrupted sleep duration, while others described the 
Coast Guard's efforts to address hours of service as minimal and in 
need of revision. Another commenter said mariners resent the Coast 
Guard's failure to take a stand on maximum work hours and safe minimum 
manning requirements.
    In the NPRM, the Coast Guard shared its views on potential HOS and 
CEMS program standards and requirements, and sought additional data and 
other information that we solicited through specific questions because, 
as we stated, we are ``considering establishing hours of service 
standards and requirements for managing crew endurance, the ability for 
a crewmember to maintain performance within safety limits while 
enduring job-related physiological and psychological challenges.'' (76 
FR 49991, Aug. 11, 2011.)
    We received several comments suggesting that the traditional 2-
watch system be replaced by a 3-watch system that provides more 
opportunity for increased uninterrupted sleep. One commenter said work 
durations should be reduced to a maximum of 21 days, with a phase-in of 
the 3-watch system within 10 years. Another commenter recommended that 
the Coast Guard develop a NVIC to provide one or more specific 2-watch 
rotation models that would meet the work hour limitations and minimum 
rest hour standards.
    Several commenters noted that a ``6-on, 6-off'' schedule is unsafe 
or insufficient for allowing adequate rest. One commenter said an ``8-
hour on, 4-hour off; then 4-hour on, 8-hour off'' schedule would 
achieve the maximum hours of rest while maintaining the current amount 
of crew. However, another commenter said an ``8:8:4:4'' schedule may 
allow for less total sleep over 24 hours than a ``6:6:6:6'' schedule.
    We received several comments referencing crew manning with respect 
to potential work hour requirements. Some commenters said any towing 
vessel operating over 12 hours in any 24-hour period should be manned 
with two full crews, not just with two licensed officers. One commenter 
recommended a safe manning level that would support a 3-watch system 
for vessels towing laden tank barges containing oil or hazardous 
material in bulk. Another commenter stated that the Coast Guard should 
require a relief pilot or three pilots onboard vessels (captain, after 
watch pilot, and swing pilot). Several commenters noted that crews are 
increasingly undertaking administrative duties, which can impact 
appropriate manning and mariners' opportunity for rest.
    An element of a CEMS that might improve the awareness of the lack 
of opportunity for crew members to obtain adequate sleep would be to 
keep a record of each crew members' work and rest schedule. We note 
that NVIC 02-08, Enclosure (4), provides a CEM program evaluator 
checklist to capture areas that need improvement and ways to go about 
addressing those areas. Page 4 of Enclosure (4) provides an example of 
how a crew member might analyze their current work/rest schedule to 
identify any associated risks involving fatigue.
    Several commenters suggested regulations that limit the workday to 
12 hours in a 24-hour period for all mariners. One commenter said the 
NPRM should mandate maximum work-hour limitation for unlicensed 
personnel and maximum allowable work days and rotations.
    We received numerous other comments. One commenter said that 
without clear and enforced work-hour regulations and independent third-
party inspections, towing boat companies will continue to exploit crews 
who are eager to remain employed.
    One commenter urged the Coast Guard to promulgate HOS regulations 
consistent with NTSB Safety Recommendation M-99-1. A maritime company 
recommended minimum hours of rest similar to those set forth in the 
latest STCW (Manila) amendments (STCW 2010, Chapter VIII, Section A-
VIII/1).
    One association noted that the Coast Guard should have decided this 
issue ever since that association first presented it in May 2000 in 
National Mariners Association Report #R-201 titled ``Mariners Speak Out 
on Violations of the 12-Hour Work Day.''
    We received several comments supporting the implementation of an 
HOS rule that would allow for sufficient time off to obtain at least 8 
uninterrupted hours of sleep, or at least 7 hours of uninterrupted 
sleep and an additional sleep period in every 24 hour period. However, 
some commenters said the current statutory requirements in 46 U.S.C. 
8104(g) are sufficient.
    Several commenters opposed a requirement for a minimum of 7 to 8 
hours of uninterrupted sleep for personnel on towing vessels. A 
maritime company responded that requirements should consist of a 
minimum of one 6-hour period of uninterrupted rest within a 24-hour 
period and a minimum of 10 hours per day of total rest. Two commenters 
stated that the NPRM's focus on a minimum of 8 hours of uninterrupted 
sleep fails to acknowledge that a long sleep period in conjunction with 
a nap of shorter duration during a 24-hour period do not result in a 
compromised mental and physical state. Similarly, a commenter

[[Page 40077]]

said it is not the number of uninterrupted hours of sleep per day that 
is important for performance and maintenance of alertness, but rather 
the total hours of sleep per 24 hours. Also, the commenter said data 
indicates that shift workers who work 8 hours and have 16 hours off to 
sleep only obtain 5 to 6 hours of sleep when sleep occurs at the 
``wrong'' circadian time.
    We received one comment saying the best method is to allow for 
anchor sleep to occur during one sleep opportunity and a nap sleep to 
occur during the second sleep opportunity. A maritime company responded 
that a Safe Manning Document, with prescribed watch requirements taking 
into account the vessels route and service requirements, would be the 
best way to ensure that sufficient qualified personnel are available 
for 12 hours of work per day.
    A maritime company responded that the direct financial impact on 
its company would be minimal, as most of its vessels are already manned 
to allow for 7 or 8 hours of uninterrupted sleep (three in each 
department). However, the commenter noted that the company would lose 
some level of oversight and daily productivity in performing, for 
example, inspections and maintenance.
    One commenter stated that sufficient uninterrupted sleep for vessel 
crew is the best insurance a vessel owner or managing operator can have 
against casualties. A maritime company stated that there would be a 
benefit to managing work periods in relation to safety, but setting a 
minimum number of consecutive hours without changing the 12-hour work 
period may make it difficult to manage vessel operations in a 24-hour 
period.
    One commenter responded that allowing crews a 7- to 8-hour sleep 
opportunity does not mean crewmembers will routinely obtain 7 to 8 
hours of uninterrupted sleep because it is impossible to mandate sleep.
    We agree that a mandate to provide an opportunity for a sufficient 
number of hours of uninterrupted sleep will not guarantee that 
crewmembers sleep for the desired number of hours. But as we suggested 
in the NPRM, providing the opportunity ``to increase uninterrupted 
sleep duration to a threshold of at least 7 consecutive hours in one of 
the two available off periods in the two-watch system [would] increase 
the probability that crewmembers will have the opportunity to restore 
the cognitive abilities necessary to maintain situational awareness, 
even if the sleep environment is not optimal.'' 76 FR 49996, Aug. 11, 
2011. As noted above, log-keeping could be an effective way to gauge 
work and rest schedules throughout daily onboard operations.
    A maritime company responded that while 7 hours of sleep is ideal, 
this does not work well in a 12-hour work schedule, and is still 
controversial even within the pioneering companies that initially 
implemented and tested the CEMS practices. The commenter concluded that 
the CEM training teaches that this--getting 7 hours of sleep--is the 
last and one of the least important facets of the program.
    Another maritime company responded that, when given a 7- to 8-hour 
sleep opportunity, mariners cannot obtain 7-8 hours of uninterrupted 
sleep. Thus, it is common in the towing vessel industry to allow for 
two sleep opportunities where each opportunity allows for significant 
sleep such as on a ``6:6:6:6'' square watch schedule.
    We received many comments, mostly from maritime companies, opposing 
a potential requirement for a minimum of 7 to 8 hours of uninterrupted 
sleep for personnel on towing vessels because no current watchstanding 
system meets this standard. Several commenters, including maritime 
companies, said the ``6 on/6 off'' watch schedule has worked for many 
years and should not be altered. A maritime company responded that the 
traditional ``6 on/6 off'' watch schedules would have to be changed to 
a ``5/7/7/5,'' or'' 4/8/8/4,'' and a ``12/12'' schedule may even need 
to be worked depending on vessel operations. Another commenter 
expressed concern about the difficulty that operators would have in 
finding experienced personnel to meet the proposed watch standing 
standards.
    One commenter responded that it is impossible to mandate that 
mariners ``obtain a required number of hours of uninterrupted sleep, 
such as 7-8 hours.'' Instead, what is needed is to change mariner 
culture such that sufficient sleep is understood to be important for 
optimal performance, safety, and health.
    A maritime company said a mandate would undoubtedly change the 
entire operation onboard, including meal hours, voyage planning, etc.
    Another maritime company responded that a mandate that required 
mariners to obtain 7 to 8 hours of uninterrupted sleep would require 
the use of pharmacological agents or behavioral therapies (e.g., 
exercise, sleep hygiene, cognitive behavioral therapy for insomnia) 
that would enable mariners to achieve the mandated hours of 
uninterrupted sleep.
    One commenter noted that many factors, including electronic 
gadgets, noise in the berthing spaces, and dietary considerations can 
have an adverse impact on a mariner's ability to obtain adequate sleep.
    We received one comment that said requiring 7 to 8 hours of 
uninterrupted sleep would require one-third more crewmembers than the 
company presently can accommodate on board.
    One commenter stated that recent data on sleep make it unlikely 
that crews on a ``7:7:5:5'' or an ``8:8:4:4'' watch schedule could 
obtain close to 7 or 8 hours of sleep, even when the endogenous drive 
to sleep coincided with a 7- or 8-hour rest period.
    Two commenters said focus on nutrition and hydration has helped 
employees, but the companies have not changed watch schedules. Two 
other commenters responded that they have implemented CEMS, but one 
noted that it does not require that mariners receive 7 to 8 hours of 
uninterrupted sleep.
    An association and another commenter said a CEMS program alone 
cannot account for the fatigue caused by the existing 2-watch system on 
vessels in 24-hour service. The commenters stated that many mariners 
are unwilling to adjust their lives to fulfill the requirements of the 
system, and employers who force the program upon their mariners will 
encounter resentment and retention problems.
    A maritime company responded that if a CEMS program enabled crews 
to obtain 7 to 8 hours of total sleep over a 24-hour period, such a 
program could be effective in combating fatigue. Another maritime 
company responded that any operation can benefit from CEM practices 
absent of work/rest changes. Diet, exercise, and environmental factors 
are all critical to improving operations and reducing fatigue.
    Another maritime company responded that there is no evidence HOS 
restrictions reduce casualties and injuries, although this may be 
possible if crews can achieve 7 to 8 hours of total sleep on a day-to-
day basis.
    A maritime company commented that no existing programs could be 
considered equivalent to the Coast Guard CEMS program. The alternative 
would be a traditional ship ``4/8'' watch schedule, which would require 
manning increases for most companies.
    One commenter responded that, yes, a mandate would cause burden to 
smaller companies with limited resources. Another commenter said 
requiring a crew management program would increase the already large 
financial burden of implementing these proposed regulations on mid-
sized and smaller companies, as well as an increased cost to the end 
consumer due to the necessity of larger crews.

[[Page 40078]]

    A maritime company responded that for a full CEMS program, a 4- to 
5-year period would be appropriate to allow for training, 
implementation, and auditing. Another maritime company responded that 
there is no appropriate phase-in period or method until evidence is 
provided that implementation of a new HOS requirement is effective.
    In their comment to the docket (USCG-2006-24412-0187), the National 
Transportation Safety Board indicated they were pleased with the 
comprehensiveness, relevance, and timeliness of the literature that the 
Coast Guard cited in the NPRM, and believes that this literature aptly 
summarizes the state-of-the-art of human factors and physiological 
research on the effects of fatigue on human performance. The commenter 
went on to cite several maritime and transportation accidents in which 
operator fatigue was identified as a contributing factor.
    A maritime company noted that Coast Guard cites the Fatigue 
Avoidance Scheduling Tool (FAST) algorithm and produces nine figures 
(Figs 2-10) for assessing the effects of work and rest schedules on 
human health and performance, but there is no evidence in the FAST 
model that mariners will be able to obtain 7 to 8 hours of 
uninterrupted sleep on a ``7:7:5:5'' or ``8:8:4:4'' rectangular watch. 
Another maritime company disagreed with scientific studies that have 
indicated that uninterrupted sleep of less than 8 hours gives a worker 
a response time equivalent to someone with blood alcohol content of 
0.05-0.08. Other commenters recommended a study on sleep requirements 
strictly related to inland waterways vessels.
    We received a few comments supporting the structure of a CEMS 
program, and stating that before work hours or watchstanding practices 
are changed, a program including crew physical wellness and fatigue 
education and training must be put into place. One commenter supported 
additional training for crew members in the area of crew member fatigue 
and work and rest periods.
    There are currently several opportunities to learn more about CEMS 
and mariner fatigue. We recommend talking with your company safety 
officer for training options, or visit http://www.uscg.mil/hq/cg5/cg5211/cems.asp for more information on CEM.
    One commenter said the concept of crew endurance is in effect a 
``Band-Aid'' for a system that is broken, and that the Coast Guard has 
objective scientific evidence to take clear and definitive actions for 
establishing maximum work-hour limitations.
    We received several comments stating that the Coast Guard's 
emphasis on uninterrupted sleep differs from the description of CEMS in 
NVIC 02-08, Criteria for Evaluating the Effectiveness of Crew Endurance 
Management System Implementation. Further, the commenters said NPRM's 
emphasis on 7 to 8 hours of uninterrupted sleep is troubling not only 
because of its inconsistency with prior Coast Guard publications 
describing the purpose of CEMS, but more importantly because it 
reflects an incomplete and selective treatment of the science behind 
sleep and watchstanding.
    As discussed in NVIC 02-08, components of a CEMS that improve the 
safety culture and sleep quality include education, environmental 
changes, light management, trained coaches, and schedule changes. As 
indicated in Enclosure (4) of NVIC 02-08, a crew's watch schedule 
should be evaluated based on the opportunity for each member to achieve 
a sufficient amount of uninterrupted sleep.
    A maritime company stated that the CEMS demonstration project did 
not provide any data to support any changes in HOS or any endurance 
management standards.
    We received several comments complaining about the Coast Guard's 
inaction regarding HOS and crew endurance. However, many commenters, 
mostly maritime companies, said the towing vessel inspection rule is 
not the proper place for requirements regarding fatigue management, 
which has implications for the entire maritime industry and that it 
would be more appropriate to address the issues raised in the NPRM 
relating to periods of rest and watchstanding in a separate rulemaking 
project particularly as it pertains to the marine industry as a whole. 
One commenter said any additional CEMS requirements should be 
identified in a company's TSMS and not in regulation.
    Several commenters said emphasis on minimum required hours of sleep 
is not justified by science or data. One commenter said the NPRM is 
confusing and lead a reader and, more importantly, an inspector to draw 
the wrong conclusions about how a vessel watch should be set up. A 
maritime company said there is a need for literature that explores 
anchor sleep/nap sleep strategies; compares sleep times on different 
watch schedules where the total amount of sleep and work opportunities 
are equivalent; evaluates the effectiveness of educational programs to 
change the culture of crews on board towing vessels; documents why 
mariners do not obtain 7 to 8 hours of sleep per 24 hours; and 
evaluates effective strategies for the treatment of sleep disorders.
    One commenter said any requirement for hours of service standards 
and crew endurance management requirements should apply to double-
crewed overnight boats and should not apply to ``dinner bucket'' or 
harbor boats.
    We received two comments stating that the Coast Guard should 
withdraw its proposal until the following issues are addressed: current 
abuses of existing hours-of-service regulations for towing vessel 
officers; the lack of any hours-of service regulations for deckhands, 
engineers and unlicensed crewmembers; fatigue resulting from these 
abuses; and the undermanning of towing vessels as previously 
documented.
    Another commenter said the NPRM included no mention of previous 
recommendations made by the Towing Safety Advisory Committee (TSAC) on 
CEMS and seeks comment on a different approach that was not previously 
brought to TSAC's attention.
    We received several comments stating that the CEMS research being 
conducted by Northwestern University on inland towing vessels should 
influence the Coast Guard's direction on watchstanding and CEMS.

Q. Economic Analysis Comments

    The Coast Guard received numerous comments from organizations and 
individuals regarding the costs and benefits associated with our 
proposed subchapter M regulations.
    When we published the NPRM in 2011, we were particularly interested 
in the economic impact of implementing a TSMS, and whether there were 
alternatives to the TSMS and Coast Guard inspection options that could 
provide similar benefits at a lower cost.
    Many commenters provided details and opinions regarding the costs 
and benefits of implementing the new subchapter M requirements. The 
comments involved the overall and specific costs and benefits of the 
requirements, the economic impact on small entities, and the requests 
for flexibilities that could provide relief to towing vessel owners and 
operators. We appreciate these comments and have attempted to integrate 
them into our Regulatory Analysis (RA). We address the specific topics 
in the sections of this preamble below.
1. Costs
    We received numerous comments from towing vessel industry 
stakeholders regarding the specific costs

[[Page 40079]]

of subchapter M parts as well as general remarks on overall costs of 
the new requirements. Many commenters expressed concern over subchapter 
M requirements imposing undue costs on vessel owners and operators 
without providing any information or further discussion.
    One commenter stated the cost of hiring a naval architect for 
stability calculations would be in the tens of thousands of dollars per 
vessel to comply with construction and arrangement standards, and 
verification of compliance with those requirements.
    As noted above in section IVI.N, the Coast Guard has added 
additional options for verification of compliance with part 144. 
Section 144.300(b) now offers three options for an existing vessel 
without a stability document to meet part 144 requirements: findings 
based on the vessel's operation or a history of satisfactory service, 
successful performance on operational tests, or a satisfactory 
stability assessment. None of these options would cost this operator 
tens of thousands of dollars. For example, the findings based on the 
vessel's operation or history of satisfactory service is a 
documentation activity that the Coast Guard estimates will require 4 
hours of time to compile at a cost of approximately $200. Operational 
tests are undertaken as part of a standard inspection if needed at no 
additional cost to the operator.
    The commenter also believed that additional equipment and 
redundancy systems--specifically propulsion, steering and related 
controls, electrical installations, pilothouse alerter system and 
towing machinery--required by part 143 are unnecessary.
    As discussed earlier, part 143 no longer requires redundancy 
propulsion or steering for existing vessels, and has eliminated 
deferred electrical requirements in proposed Sec. Sec.  143.340 through 
143.360 for existing vessels. This final rule does retain a pilothouse 
alerter system requirement for towing vessels with overnight 
accommodations and alternating watches (shift work), but we have 
limited this requirement to towing vessels more than 65 feet in length. 
We also retained a requirement for towing machinery (e.g., capstans and 
winches) to be designed and installed to maximize control of the tow. 
Both the pilothouse alerter system and towing machinery requirements 
have a delayed implementation period for existing vessels: 5 years 
after the issuance of the first COI for the vessel. For a more detailed 
discussion of these two requirements, please see section IV.M above.
    One commenter stated that the Coast Guard estimated that bringing a 
single towing vessel into compliance with general requirements for 
propulsion, steering, and related controls, which appeared in Sec.  
143.405 in the NPRM, would cost $20,000 and said that his company spent 
$200,000 to replace steering and propulsion systems of a single vessel. 
The commenter estimated that to bring his company's 130 vessels into 
compliance under subchapter M, they would need to spend millions of 
dollars. The commenter also said that several thousand towing vessels 
would be affected, as opposed to the Coast Guard estimate of 26 towing 
vessels being affected by the Sec.  143.405 requirements.
    As discussed earlier, the Coast Guard acknowledges the potential 
for higher costs to retrofit existing vessels. In this final rule, the 
relevant requirements have been moved to Sec.  143.585 and the 
applicability of these requirements has been reduced to only apply to 
new vessels (estimated at 88 per year) or those undergoing a major 
conversion (estimated at 13 per year) that move tank barges carrying 
oil or hazardous materials in bulk. We estimate the incremental cost to 
comply with Sec.  143.585 during the design and construction stage for 
new vessels or those undergoing major conversion to be $10,000 per 
vessel.
    Another commenter, referencing the previous commenter's remarks, 
estimated that company would incur a cost of $40 million to comply with 
subchapter M. This commenter also suggested that subchapter M costs 
will be passed along to all the consumers in the U.S. economy thereby 
putting the U.S. economy at a disadvantage compared to other world 
economies.
    The Coast Guard has considered the potential cost impact on 
individual companies and the economy in formulating the final rule. We 
balanced costs against the beneficial impacts of the rule in reducing 
the risk of towing vessel accidents and the resulting consequences, 
including fatalities, injuries, and oil spills. Based on information 
provided in the comments from the public on the costs of some 
requirements, we have revised the applicability of some those 
requirements to only newly constructed or refurbished vessels to 
mitigate the need for costly retrofits of existing vessels. We have 
also added alternative compliance options, such as allowing service 
history in lieu of stability tests for some vessels. We believe the 
resulting final rule fulfills Congress' mandate to bring towing vessels 
under an inspection system to ensure and improve safety, while 
minimizing costs and potential impacts on the U.S. economy.
    Another commenter expressed concern about the cost of the rule to 
vessel owners and operators and stated that the annual user fee could 
be ``in the $1,000 to $2,000 range'' for each vessel. The annual fee 
for towing vessels inspected under subchapter M will be $1,030. As we 
note in section IV.D above, this is the existing annual inspection fee 
in 46 CFR 2.10-101 for any inspected vessel not listed in Table 2.10-
101. This will be charged starting a year after the initial COI is 
issued and will remain the annual inspection fee until a specific 
annual inspection fee for towing vessels is promulgated through a 
separate rulemaking.
    The same commenter also estimated that the negative impact on the 
economy, of (river-canal) lock delays due to towing vessel accidents, 
is only $13.89 million of annual economic impact and 0.13 percent of 
total downtime, compared to an estimated total negative economic impact 
of $10.8 trillion for all downtime on the lock.
    The Coast Guard acknowledges that lock delays from towing accidents 
may only make up a small fraction of total lock delays. However, that 
does not negate the benefit that could be realized through the rule by 
improving towing vessel safety, and reducing accidents and the 
resulting delays. Analyzing all causes of lock delays and methods for 
mitigating those delays not related to towing vessel accidents is 
outside the scope of this rulemaking.
    One commenter submitted a number of comments on the additional 
operational costs due to subchapter M requirements that included the 
impact of periodic drydocking which may leave the work force idle, 
additional recordkeeping-staff requirements, the limited supply of 
shipyards which may increase the amount of time needed for repairs and 
drydocking, and increases in lending rates for marine loans from 
financial institutions due to actual or perceived risks.
    With respect the impact of drydocking, according to a 2013 report, 
``For smaller vessels, routine drydocking can be done in the course of 
a single day.'' \7\ The Coast Guard assumes 2 days of for each drydock 
inspection and has added an estimate of potential lost revenues during 
that period. Drydocking can be scheduled in advance with shipyards to 
coincide with rest requirements of crew, minimizing the

[[Page 40080]]

potential for workforce idleness or longer waits times.
---------------------------------------------------------------------------

    \7\ ``Study of Engineering and Naval Architecture Costs for Use 
in Regulatory Analysis'', 17 April 2013 by ABS Consulting, page 30.
---------------------------------------------------------------------------

    The provisions of the rule are intended to improve safety of towing 
vessel operations, which over time should reduce actual risks.
    One commenter asked for more detail on how the Coast Guard 
estimated the annual government costs at $1.4 million. He interpreted 
this figure as a need to hire 14 new full time employees.
    Coast Guard man-hours are calculated based on assuming only a few 
hours per vessel, although it might amount to a large number of hours 
considering that the affected population is more than 5,500 towing 
vessels. The Coast Guard is flexible with respect to meeting resource 
needs and may not hire new full time employees to implement the new 
subchapter M program.
    Several commenters stated that the preliminary RA underestimated 
the various costs of subchapter M. In particular, one commenter 
believed that for existing vessels cost in man-hours needed to develop 
vessel plans is much higher than the estimate presented in the RA. The 
commenter estimated that cost of plan development alone will be as high 
as $80,000, as opposed to the Coast Guard estimate of $20,000. In 
addition to these costs, the commenter included an estimate of up to 
$30,000 for stability review, and $100,000 to verify vessel compliance 
with requirements in parts 140 through 144.
    The Coast Guard acknowledges the potential for higher costs for 
plan development and stability review. As a result, this final rule 
does not require an existing vessel to undergo a verification of 
compliance with design standards, so there is no plan development cost 
for an existing vessel unless that vessel either undergoes a major 
conversion or involves a new installation that is not a replacement-in-
kind. In the case of a major conversion, the plans and documentation 
needed would be directly related to the scope of the conversion. In the 
case of an installation that is not a replacement-in-kind, the plans 
needed would be limited to the scope of the installation and to prove 
that the vessel meets stability standards. Moreover, the documentation 
required is not restricted to traditional drawings; sketches, 
schematics, diagrams, specifications, and photographs can be used to 
the degree needed to ensure the vessel complies with the standards 
used.
    The same commenter suggested an alternative approach to these plans 
that they estimated would cost no more than $30,000 per vessel: Having 
a P.E. conduct a ship check to approve hull structure, piping, 
electrical machinery systems and stability test by using in-house 
sketches and reviewing vessel structure and systems. The total costs of 
the program suggested by this commenter ranged from $150,000 to 
$180,000 when added to the other vessel plan costs. The Coast Guard 
views the suggested alternative approach to be similar to the surveys 
required under the TSMS option and, therefore, to be redundant. 
Further, the alternative approach suggested is not really an 
alternative since sketches, photographs, and similar documents are 
included in the group of sufficient documents needed for review in the 
case of either a major conversion or a new installation that is not a 
replacement-in-kind on an existing vessel.
    Another commenter estimated that the cost of retrofitting an 
existing towing vessel to comply with subchapter M ranges from $180,000 
to $300,000. This commenter also pointed out the additional cost of a 
TSMS, which he noted we estimated to be from $61,000 to $150,000 per 
company. The commenter added that none of these estimates accounts for 
the economic impact of time spent out of service while a vessel is 
being retrofitted.
    The Coast Guard acknowledges that the costs to retrofit vessels to 
meet certain proposed requirement may have been higher than estimated 
in the NPRM. As a result of these higher costs, the Coast Guard has 
removed those requirements for existing vessels, although the 
requirements are retained for new vessels as the incremental costs for 
a new vessel are lower. Removing certain requirements for existing 
vessels in Part 143 has the potential to reduce most, or perhaps all, 
of the $180,000 to $300,000 costs noted in the comment. With regards to 
the TSMS costs, the rule provides the Coast Guard inspection option as 
an alternative if developing and implementing a TSMS is deemed too 
costly by a vessel owner. In response to this and other comments, the 
Coast Guard has included an estimate of lost revenue in the Regulatory 
Analysis for the final rule for drydock inspections and activities to 
correct deficiencies that exceed 1 day in duration. We have made 
certain requirements no longer apply to existing vessels and has made 
many other changes to address that concern, as discussed in previous 
sections.
    One commenter stated that subchapter M would require his company to 
change electrical systems on existing vessels at a cost of more than 
$75,000 per vessel, and would potentially cost the company $2,700,000 
to comply.
    While the Coast Guard finds it unlikely that it would cost over 
$75,000 to bring a vessel in active service under normal engineering 
practice into compliance with subchapter M, the Coast Guard 
acknowledges that some of the requirements proposed for electrical 
systems that required retrofitting of existing towing vessels could 
result in higher costs. In this final rule, we have made many of those 
requirements only applicable to new vessels. For more details, see 
discussion of electrical systems in section IV.M above.
    One commenter estimated his company's average compliance cost to be 
$225,000 per vessel or $3.375 million for his entire fleet. A second 
commenter, relying on an AWO figure, estimates the cost of the proposed 
requirements to be as much as $100,000 per towing vessel. A third 
commenter, representing a group of offshore towing vessel owners and 
operators, quoted previous comments on compliance costs and provided an 
average cost of $180,000 to $300,000 per vessel.
    The Coast Guard appreciates the information from commenters on the 
potential costs of the proposed requirements in the NPRM. Given the 
potential for higher cost impacts, we have re-evaluated the 
requirements in the proposal to identify opportunities to minimize 
costs while still achieving risk reduction. As described previously, we 
have provided opportunities for lower-cost compliance options for some 
requirements and changed the applicability of some requirements so that 
existing vessels would not have to undergo costly retrofits. The Coast 
Guard estimates that the average cost of compliance per vessel during 
the phase-in period is $16,267 with an additional $5,045 cost per 
company. The deficiency data from the Bridging Program and towing 
vessel boardings, which represents over 99 percent of the towing vessel 
fleet, indicates that many deficiencies are relatively rare (5 percent 
or less of vessels), making it unlikely that a vessel would incur the 
cost of every regulatory requirement.
    Finally, other commenters stated that there are many hidden or 
unaccounted-for costs that the Coast Guard did not incorporate into its 
preliminary RA. These hidden costs are the same costs mentioned by a 
previous commenter: Lost revenues and wages due to periodic inspections 
and repairs (including travel to inspection locations), crew costs to 
prepare for the inspection and undergo the questioning during the audit 
or survey, and management costs to oversee the TSMS and inspection 
scheduling.

[[Page 40081]]

    Based on these and other comments, the Coast Guard acknowledges 
that potential for lost revenue and has added an estimate of lost 
revenues for drydocking and certain repairs (please see Section 2.5 of 
the Regulatory Analysis for details).
    With respect to costs to prepare for and undergo inspections, the 
Coast Guard estimates 40 hours of time to prepare for and undergo an 
inspection, which could be accomplished by the owner, operator, crew, 
or a combination. We have used the owner or operator wage rate to value 
the opportunity cost, which would be a slight over-estimate if crew 
instead performed the activities, which includes scheduling the 
inspections.
    With regard to management costs to oversee a TSMS, the NPRM 
regulatory analysis provided an overall cost estimate for a TSMS that 
included management costs. For the final rule, the Coast Guard does not 
expect management costs for a TSMS to be incrementally different than 
management costs for an existing Safety Management System.
    Additionally, one commenter believed that the preliminary RA did 
not account for increased shipping rates and transportation costs for 
industries dependent on river transportation.
    The Coast Guard has added an evaluation of the potential for 
increased shipping rates and transportation costs in Appendix J of the 
Regulatory Analysis. The average cost per vessel of the final rule on a 
daily basis represents an increase of 0.7 percent to 2.75% of barge 
daily operating costs, exclusive of fuel costs. The ability of towing 
vessel owners to pass along these cost increases to shippers will 
depend on many factors that make up the elasticity of demand, which 
will vary depending on the cargo, route, and transportation 
alternatives available. Towing vessels and barges typically carry 
commodities in bulk, including coal, petroleum, crude materials (such 
as forest products, sand, gravel, ores, scrap, and salt), and food and 
farm products (Figure J-1). The analysis of the impact of the increase 
in towing vessel daily operating costs on the shippers will be 
different for each commodity and route. An analysis of shipping rates 
for grain indicates that barge shipping rates are volatile, sometimes 
doubling from one year to the next, reacting quickly to sudden changes 
in export demand, weather constraints on the rivers, or larger-than-
expected crops. The final rule requirements are expected to represent 
average increases in operating costs of 0.7 to 2.75 percent, only a 
small fraction of normal variability in rate. The market and shippers 
have adapted to fluctuations in shipping rates, so that increases of 
the size that may result from the final rule are within normal 
variations.
    Further, the amount of increase in costs will vary from company to 
company. For example, many companies already have a TSMS, so this 
regulation would have a lesser impact on those companies cost structure 
than those companies that don't have one. The final rule brings all 
towing companies up to a minimum standard of safety and erodes the 
competitive advantages of those companies underinvesting in safety 
measures. By reducing accidents, incidents and casualties and resulting 
impacts including delays, the final rule may also increase the 
dependability and timeliness of shipping by barge and perhaps mitigate 
some limited aspects of the volatility of rates.
2. Benefits
    We received many comments in support of the proposed rule. Many 
commenters said that SMSs are cost-beneficial and might lead to 
quantifiable benefits. Commenters suggested that SMSs might lead to 
benefits such as fewer vessel accidents and personal injuries, which 
would mean cost savings from reduced insurance premiums and avoidance 
of expenses such as vessel repairs and time out of service. However, no 
commenter provided any data or analysis that would directly quantify or 
monetize such benefits.
    Numerous commenters, while agreeing with the proposed requirements 
in principle, expressed a concern that the costs of complying with 
subchapter M would exceed the benefits and should be either avoided 
altogether or mitigated by following a risk-based approach. The 
majority of these commenters felt that benefits should be justified by 
each towing vessel's individual casualty history and risk. For example, 
a vessel that has not been involved in any accident but is not 
compliant with some or all of the requirements of subchapter M should 
not be considered a risk to the maritime industry and should be granted 
exemption or grandfathered from some or all of subchapter M 
requirements.
    The Coast Guard agrees in part. The regulatory impact analysis we 
provide in the docket discusses at length why and how owners and 
operators of regulated entities will benefit from the requirements of 
the final rule. The fact that no incident has occurred yet on a 
particular vessel, especially one that does not comply with the 
requirements of the final rule, does not mean that the vessel does not 
present any risk to the maritime industry. In the next comment section, 
we addressed requests to obtain relief from certain costs commenters 
deemed unnecessary and will point to accomodations and flexibilities 
this final rule provides.
3. Flexibilities To Provide Relief to Towing Vessel Owners and 
Operators
    We received numerous comments from the towing vessel owners and 
operators requesting greater flexibility in the rule to reduce its 
costs to them. They varied from full exemption from all subchapter M 
regulations to grandfathering on specific requirements. These comments 
are addressed in this section.
    One commenter requested that the Coast Guard grant his company 
either an exemption from all requirements of subchapter M or an 
extension of 20 years of grandfathering on existing equipment on board 
his towing vessels. Another commenter requested some form of 
grandfather clause for existing fleets from proposed Sec. Sec.  143.340 
through 143.360 electrical system requirements citing complete rewiring 
costs at $150,000 to $210,000 for each vessel. Similarly, one 
commenter, without being specific, suggested that many requirements 
relating to mechanical and electrical equipment and structural 
standards for small operators should be relaxed or eliminated. Also, 
the AWO recommended that the Coast Guard delete sections on electrical 
system requirements in the final rule. Another commenter argued that 
subchapter M regulations are unnecessary and asked for an exemption or 
extension for longtime existing companies that have always operated in 
full compliance with existing regulations because these new regulations 
may force them out of business.
    The Coast Guard believes it inappropriate to grant an exemption 
from all new requirements under subchapter M or grandfathering of 20 
years for existing equipment. However, the Coast Guard agrees that some 
of the requirements for machinery and electrical systems in part 143 
may have been too burdensome and were unnecessary for existing vessels, 
so they have been removed from this final rule.
    One commenter suggested that coal and grain barge handlers, which 
are generally small businesses, should not have the same TSMS 
requirements as larger companies. Another commenter asked Coast Guard 
to provide a template for a scaled-down version of a TSMS that might be 
less overwhelming for small towing vessel operations. A third

[[Page 40082]]

commenter suggested that small operators should not be required to 
implement and maintain certain parts of the TSMS, such as the 
Behavioral-Based Safety program.
    In the final rule, TSMS requirements are neither modified for 
different classes of towing vessels nor scaled down or exempted for 
small towing vessel operators. However, as previously noted, the TSMS 
is scalable. It can be tailored to the operation of a small company and 
simplified to address a limited set of assets, process, and personnel. 
For a small business operator with a fleet of one or two vessels the 
TSMS may be a short document. Further, owners and operators can choose 
the Coast Guard inspection option.
    Behavior-based safety has been described as an approach that 
focuses on what people do, analyzes why people take these actions, and 
then applies a research-supported intervention strategy to obtain a 
more desired outcome. (Geller, E. Scott, 2004). Subchapter M does not 
specifically prescribe the use of behavior-based safety to address 
specific elements of the TSMS, however some companies have chosen to 
use this approach to help modify employees behaviors to enhance safety 
within their organization.
    We do not believe a template is needed to comply with TSMS 
requirements. As discussed in previous sections, we have clarified TSMS 
requirements in this rule and we intend to issue guidance documents 
related to TSMSs and TPOs as necessary, and these guides may contain 
examples of such documents.
    One commenter stated that the TSMS should be the only approved 
method (to obtain a Certificate of Inspection) under the final rule and 
recommended that the Coast Guard option be removed because a TSMS is 
scalable and can be developed in a cost-effective manner that many 
small companies can adapt to.
    The Coast Guard disagrees that the TSMS should be mandatory. 
Although we recognize that the TSMS is scalable and can be developed in 
a cost-conducive manner, some towing companies may lack the resources 
or expertise to develop and implement a TSMS. The Coast Guard 
inspection option is intended to provide greater regulatory flexibility 
to such companies, or any that may not want to use a TSMS for other 
reasons. As noted above in section IV.B, offering this option is 
consistent with one of ABSG Consulting's recommendations in its 2006 
final report to the Coast Guard. See docket submission USCG-2006-24412-
0017.
4. Small Business Impacts
    We received several comments from small business owners and 
operators on the economic impact of subchapter M requirements. Some 
were opposed to the new requirements, but did not provide specific 
information or data about how they would be impacted. Others requested 
either an exemption or grandfathering from some or all of the 
requirements, so that they could avoid or mitigate the economic impacts 
and continue to serve the towing vessel industry. A discussion of 
comments received on small business impacts follows.
    Many commenters felt that subchapter M requirements would hurt 
small business owners and their employees and could put many small 
entities out of business. However, they did not provide specific data 
as to how much of an economic burden they expected the new requirements 
to place on their operational costs. The most specific comment was that 
new recordkeeping requirements alone would mean that the owner or 
operator would have to hire one or more new full time workers. Other 
commenters estimated the overall costs of subchapter M requirements in 
a range of $100,000 to $250,000 per vessel and several million dollars 
per company.
    Other commenters expressed concern that their companies would not 
be able to pay for these unspecified subchapter M requirements, and 
therefore, either be forced out of business or be acquired by larger 
entities in the towing vessel industry. One commenter argued that 
lenders will delay lending and review existing ship mortgages to 
reassess their collateral positions, because many owners and operators 
of small towing vessel fleets will not be able to afford the costs to 
comply with subchapter M requirements. Another commenter stated that 
his company would lose the ability to borrow against their boats if 
they cannot comply with the new regulations. One commenter estimated 
that no less than 20 percent of the aggregate U.S. towing fleet would 
be put out of business if the NPRM, as written, is published as a final 
rule. However, these commenters did not provide specific data or 
information to support their concerns.
    The Coast Guard appreciates these comments on the potential 
economic impact of the proposed rule on small businesses. Based on 
these comments and other comments on the range of compliance costs, we 
have re-evaluated the requirements in the proposal to identify 
opportunities to minimize impacts on small businesses while still 
achieving risk reduction. As described previously, we have provided 
opportunities for lower-cost compliance options for some requirements 
and changed the applicability of some requirements so that existing 
vessels would not have to undergo costly retrofits. The Coast Guard 
estimates that the average cost of compliance per vessel during the 
phase-in period is $16,267, with an additional $5,045 cost per company. 
The deficiency data from the Bridging Program and towing vessel 
boardings (which represents over 99 percent of the towing vessel fleet) 
indicates that many deficiencies are relatively rare (5 percent or less 
of vessels), making it unlikely that a vessel would incur the cost of 
every regulatory requirement.

V. Regulatory Analyses

    We developed this final rule after considering numerous statutes 
and executive orders related to rulemaking. Below, we summarize our 
analyses based on these statutes or executive orders.

A. Regulatory Planning and Review

    E.O.s 12866 (``Regulatory Planning and Review'') and 13563 
(``Improving Regulation and Regulatory Review'') direct agencies to 
assess the costs and benefits of available regulatory alternatives and, 
if regulation is necessary, to select regulatory approaches that 
maximize net benefits (including potential economic, environmental, 
public health and safety effects, distributive impacts, and equity). 
E.O. 13563 emphasizes the importance of quantifying both costs and 
benefits, of reducing costs, of harmonizing rules, and of promoting 
flexibility.
    This final rule is a significant regulatory action under section 
3(f) of E.O. 12866. The Office of Management and Budget (OMB) has 
reviewed it under that Order. It requires an assessment of potential 
costs and benefits under section 6(a)(3) of E.O. 12866. A final 
assessment is available in the docket, and a summary follows.
    A Final Regulatory Analysis (RA) is available in the docket where 
indicated under the ``Public Participation and Request for Comments'' 
section of this preamble. A summary of the RA follows:
    This rulemaking implements section 415 of the Coast Guard and 
Maritime Transportation Act of 2004. The intent of the final rule is to 
promote safer work practices and reduce casualties on towing vessels by 
ensuring that

[[Page 40083]]

inspected towing vessels adhere to prescribed safety standards and 
adopted safety management systems. The Coast Guard recognizes that 
establishing minimum standards for the towing vessel industry is 
necessary. Vessel operation, maintenance, and design must ensure the 
safe conduct of towing vessels. The final rule improves the safety and 
efficiency of the towing vessel industry.
    In this final rule, the Coast Guard requires towing vessels subject 
to this rulemaking to undergo annual Coast Guard inspections or, in the 
alternative, be part of a safety management system. If the safety 
management system option is chosen, the rule requires companies that 
operate inspected towing vessels to create a TSMS, continue with 
existing systems that comply with the provisions of the International 
Safety Management (ISM) Code, or continue under another system the 
Coast Guard determines to be equivalent to the TSMS.
    This final rule would allow each towing vessel organization to 
customize its approach to meeting the requirements of the regulations, 
while it provides continuous oversight using audits, surveys, 
inspections, and reviews of safety data. This would improve the safety 
of towing vessels and provide greater flexibility and efficiency for 
towing vessel operators. As a result of this rulemaking, operators 
would be able to call upon third parties or the Coast Guard to conduct 
compliance activities when and where they are needed.
    Although the 2004 Act added towing vessels to the list of vessels 
subject to Coast Guard inspection and the 2010 Act directed the 
Secretary to issue a final rule on the inspection of towing vessels 
containing towing safety management system provisions, they did not 
prescribe how this inspection program must be designed, developed and 
implemented. Therefore, we consider all the new parts under the new 
subchapter M as discretionary, but integral to the safe operations of 
towing vessels and necessary to fulfill Congress' intent in the 2004 
and 2010 Acts.
    Additionally, when towing vessels receive their Certificates of 
Inspection this will trigger the following requirements outside of 
subchapter M for inspected vessels:
     Part 136, Certification will require the assessment of 
user fees, per 46 U.S.C. 2110 and 46 CFR 2.10-101, Table 2.10-101; 
(requiring user fee for vessel inspection services and certifications).
     46 CFR 15.820(a) requires a Chief Engineer on certain 
inland towing vessels.
     33 CFR 155.710(e)(1) requires a Person-in-Charge (PIC) for 
certain fuel transfers on towing vessels to be credentialed officer or 
to hold an MMC with a Tankerman-PIC endorsement.
    See the ``Discussion of Final Rule'' section for a detailed 
discussion of this final rule and see the RA for a detailed discussion 
of costs, benefits and alternatives considered. Table 3 summarizes the 
impacts of this rulemaking.

the NPRM to this final rule, and Table 5 below summarizes the changes 
in the RA. These changes to the RA came from either policy changes, 
public comments received after the publication of the NPRM, or simply

Affected Population
    We estimate that 1,086 owners and managing operators (companies) 
would incur additional costs from this rulemaking. The rulemaking would 
affect a total of 5,509 vessels owned and operated by these companies. 
Our cost assessment includes existing and new vessels.
Costs
    We estimated costs resulting from the addition of subchapter M and 
costs in other subchapters that result from the inclusion of towing 
vessels as inspected vessels, to industry and government. During the 
initial phase-in period (years 1 and 2), we estimate the annual cost to 
industry from subchapter M requirements of the rulemaking to range from 
$15.8 million to $26.5 million (non-discounted). After the initial 
phase-in, the annual costs to industry from subchapter M requirements 
range from $19.2 million to $56.4 million (non-discounted). We estimate 
the total present value cost to industry from subchapter M requirements 
over the 10-year period of analysis is $227.7 million, discounted at 7 
percent, and $286.8 million, discounted at 3 percent. Over the period 
of analysis, we estimate the annualized costs to be $32.4 million at 7 
percent and $33.6 million at 3 percent. Table 6 summarizes the costs of 
this final rule to industry for subchapter M requirements.

    Additional costs to industry for requirements outside of subchapter 
M will result from the triggering of certification for persons in 
charge during oil transfer requirements by designating towing vessels 
as ``inspected''. We estimate the total present value cost of the 
industry non-subchapter M requirements over the 10-year period of 
analysis to be $1.9 million, discounted at 7 percent, and $2.4 million, 
discounted at 3 percent. Over the period of analysis, we estimate the 
annualized industry costs for requirements outside of subchapter M to 
be $0.3 million at 7 percent and 3 percent. Table 7 summarizes the 
costs of this final rule to industry.

    We anticipate that the government will incur costs. For towing 
vessels that choose to comply with annual Coast Guard inspections, the 
government will incur costs to conduct those inspections. For other 
vessels choosing the TSMS option to comply, the government will incur 
costs to review applications for a TSMS, conduct random boardings and 
compliance examinations, and oversee third parties.
    Table 9A displays the full cost to the government. We estimate the 
total present value full cost to government over the 10-year period of 
analysis to be $85.6 million discounted at 7 percent and $110.6 million 
discounted at 3 percent. Annualized full costs to government are about 
$12.2 million at 7 percent and $13.0 million at 3 percent discount 
rates.

    The user fee paid by towing vessel owners and operators for 
obtaining the COI is a transfer from industry to the government. To 
avoid double-counting of costs, we account for this transfer by 
subtracting the amount of the user fee to be collected from the 
government costs to calculate government costs net of the transfer. 
Table 9B shows the amount of the user fees to be collected over the 10-
year analysis period.

* The total annual user fees are calculated by multiplying the total
  number of user fees collected by the user fee, $1,030.

    We estimate the total present value cost to government net of the 
transfer via user fee over the 10-year period of analysis to be $61.6 
million discounted at 7 percent and $79.5 million discounted at 3 
percent. Annualized net government costs are about $8.8 million at 7 
percent and $9.3 million at 3 percent discount rates. Table 9C

    The total, 10-year undiscounted costs of statutory mandate 
requirements are as follows:
     $38.1 million for the annual vessel inspection fees under 
46 CFR 2.10-101, Table 2.10-101 for vessels requiring a certification 
of inspection.
     $2.8 million for credentialing requirements outside of 
subchapter M that are triggered when a vessel becomes ``inspected''.
Economic Impacts of Towing Vessel Casualties
    Towing vessel casualties are incidents (i.e., accidents) that 
involve the towing vessel and possibly other vessels such as barges, 
other commercial vessels, and recreational vessels. Towing vessel 
accidents can cause a variety of negative economic impacts, including 
loss of life, injuries, property damage, delays on transportation 
infrastructure, and damage to the environment.
    Based on Coast Guard Marine Information for Safety and Law 
Enforcement (MISLE) data for the recent period of 2002-2013, towing 
vessel accidents are associated with 18 fatalities per year. Towing 
vessel accidents also result in an average of 37 reportable injuries 
per year (for the period of 2002-2013). Table 12 summarizes some of the 
negative impacts resulting from towing vessel accidents.

Benefits of the Towing Vessel Final Rule
    The Coast Guard developed the requirements in the rule by 
researching both the human factors and equipment failures that 
contribute to the risk of towing vessel accidents. We believe that the 
rule would comprehensively address a wide range of risks of towing 
vessel accidents and supports the main goal of improving safety in the 
towing industry. The primary benefit of the final rule is an increase 
in vessel safety and a resulting decrease in the risk of towing vessel 
accidents and their consequences.
    Based on Coast Guard investigation findings for towing vessel 
accident cases from 2002-2013, we estimate that the final rule would 
lead to significant reductions in fatalities, injuries, property 
damaged, and oil spilled. These improvements in safety are expected to 
occur over a 10-year period as the various provisions of the final rule 
are phased-in. Accounting for this phase-in of requirements and 
resulting benefits, we estimate total 10-year discounted benefits at 
$325.6 million discounted at 7 percent and $403.8 million discounted at 
3 percent. Over the same period of analysis, we estimate annualized 
benefits of the final rule to be $46.4 million at a 7 percent discount 
rate and about $47.3 million at a 3 percent discount rate, 
respectively. Table 13 displays the monetized benefits of this final 
rule associated with reducing fatalities, injuries, property damage, 
and oil spilled, resulting from towing vessel accidents.

Unquantified Benefits
    These estimates do not include the value of benefits that we have 
not quantified, including preventing delays and congestion due to 
towing vessel accidents. We are unable to monetize the value of 
preventing other consequences of towing vessel accidents, including 
delays and congestion, due to a lack of data and information. However, 
as discussed in the Regulatory Analysis available in the docket, the 
potential value of other benefits could be substantial if towing vessel 
accidents cause long waterway, bridge, or road closures. For large 
accidents that result in long delays, the economic consequences may 
include the following:
     Productivity losses and operating costs for stalled barge 
and other traffic;
     Delays in the acquisition of production inputs that can 
impact timely operation of manufacturing or other processes;
     Blockages of U.S. exports that can result in decreased 
revenue from importing foreign companies;
     Loss of quality for industries dealing with time sensitive 
products or products with a limited shelf life, such as commercial 
fishing seafood processors, seafood dealers, or other food processors 
and manufacturers; and
     Reduced recreational opportunities, resulting in social 
welfare losses.
    To estimate the amount of delay caused by towing vessel incidents, 
we examined the 20 most severe recorded towing vessel incidents from 
MISLE and sample cases for these other consequences and quantified 
their effects. Of the 20 incidents we were able to use archived journal 
sources and Coast Guard incident reports to estimate number of vessels 
subject to a delay and total hours of delay for 13 incidents. Based on 
our analysis detailed in the Regulatory Analysis, these 13 incidents 
resulted in 28,883 vessel hours of delay. If we apply a low end 
estimate of the costs to operate a towing vessel per hour, the delay 
costs for these 13 incidents at least exceeded $10 million. However, we 
do not have sufficient information to scale up these examples to a 
nationwide estimate.
    In addition, the evaluation of potential benefits from reducing the 
risk of accidents is dependent upon the amount of information and 
findings in the report of the incident found in MISLE. The benefit 
estimates do not include accidents for which there was a lack of 
detailed information in the case report to make a risk reduction 
determination, resulting in an underestimation of benefits. Lack of 
data in the cases of the low and medium severity incidents, implies 
that our benefits are underestimated.
Comparison of Costs to Benefits
    The estimate for the total costs of the rule is $41.5 million 
(annualized at a 7 percent discount rate). The estimate for monetized 
benefits is $46.4 million (annualized at a 7 percent discount rate), 
based on the mitigation of risks from towing vessel accidents in terms 
of lives lost, injuries, oil spilled, and property damage. Subtracting 
the monetized costs from the monetized benefits yields a net benefit of 
$4.9 million. We also identified, but did not monetize, other benefits 
from reducing the risk of accidents that have secondary consequences of 
delays and congestions on waterways, highways, and railroads.
    As shown in Table 15 below, by part, the operational requirements 
in part 140 have the highest net benefits at $9.8 million. Parts 139 
and 141 through 144 also have positive net benefits. Parts 136 through 
138 have negative net benefits of -$13.2 million. Parts 136 through 138 
contain the requirements for inspection, obtaining COIs, and TSMSs. 
These activities facilitate the enforcement of the requirements in the 
other parts, so it is difficult to separate benefits solely for the 
activities in Parts 136 through 138.

    Overall, the regulatory analysis indicates that the preferred 
alternative provides owners and managing operators of towing vessels 
the ability to customize compliance to their individual business 
models, move the industry into inspected status, and improve safety.

[[Page 40091]]

Alternatives
    At all stages of this rulemaking, including the development of the 
NPRM, review of public comments, and the preparation of this final 
rule, we considered numerous alternatives to the rule requirements. 
During this process, we weighed the burden posed by a requirement or 
group of requirements against baseline risk and potential risk 
reduction with the goal of improving safety of crew and public, and 
enhancing environmental protection, while minimizing the cost burden on 
industry and government. We have quantified the costs and benefits for 
three alternatives that are illustrative of the types and range of the 
many alternatives that considered throughout the rulemaking process. 
The alternatives explored include the following:
     Alternative 1: Limits the regulatory requirements to only 
the minimum required to meet the statutory requirements of inspecting 
towing vessels. Parts 136 to 139 are retained, related to conducting 
inspections, issuing COIs, using TSMS's and overseeing third parties. 
All operational, fire and safety, equipment and design requirements are 
removed.
     Alternative 2: Delays the operational requirements (Part 
140) from becoming effective in Year 3 of the rule (after the 2-year 
implementation period) to after the first round of initial inspections 
and issuance of COIs is complete (Year 6).
     Alternative 3: Does not ``grandfather'' existing vessels 
for certain requirements in part 143 (i.e., these requirements would 
apply to both new and existing vessels).
    Alternatives 1-3 have net costs, compared to net benefits under the 
preferred alternative. A summary of the costs and benefits of the 
alternatives are presented in Table 16.

B. Small Entities

Overview of the Final Regulatory Flexibility Act Analysis
    The Regulatory Flexibility Act (Pub. L. 96-354)(RFA) establishes 
``as a principle of regulatory issuance that agencies shall endeavor, 
consistent with the objectives of the rule and of applicable statutes, 
to fit regulatory and informational requirements to the scale of the 
businesses, organizations, and governmental jurisdictions subject to 
regulation. To achieve this principle, agencies are required to solicit 
and consider flexible regulatory proposals and to explain the rationale 
for their actions to assure that such proposals are given serious 
consideration.''
    The RFA and Executive Order 13272 require a review of proposed and 
final rules to assess their impacts on small entities. An agency must 
prepare an initial regulatory flexibility analysis (IRFA) unless it 
determines and certifies that a rule, if promulgated, would not have a 
significant economic impact on a substantial number of small entities. 
During the NPRM stage, the Coast Guard published an IRFA to aid the 
public in commenting on the potential small entity impacts of the 
provisions in the NPRM. All interested parties were invited to submit 
data and information regarding the potential economic impact that would 
result from adoption of the proposals in the NPRM.
    When an agency promulgates a final rule under 5 U.S.C. 553, after 
being required by that section or any other law to publish a general 
NPRM, or promulgates a final interpretative rule involving the internal 
revenue laws of the United States as described in 5 U.S.C. 603(a), the 
agency must prepare a final regulatory flexibility assessment (FRFA) or 
have the head of the agency certify pursuant to 5 U.S.C. 605(b) that 
the rule will not, if promulgated, have a significant economic impact 
on a substantial number of small entities. The RFA also requires an 
agency to conduct a FRFA unless it determines and certifies that a rule 
is not expected to have a significant economic impact on a substantial 
number of small entities.
    The Coast Guard did not certify that the final rule will not have a 
significant economic impact on a substantial number of small entities. 
We received comments and data from several commenters on the IRFA, and 
that information was considered for the FRFA. The RFA prescribes the 
content of the FRFA in section 604(a), which we discuss below.
    In accordance with the RFA (5 U.S.C. 601-612), the Coast Guard 
prepared the FRFA in the Regulatory Analysis document that examines the 
impacts of the final rule on small entities (5 U.S.C. 601, et seq.). A 
small entity may be:
     A small independent business, defined as any independently 
owned and operated business not dominant in its field that qualifies as 
a small business per the Small Business Act (5 U.S.C. 632);
     A small not-for-profit organization; and;
     A small governmental jurisdiction (locality with fewer 
than 50,000 people).
    This FRFA addresses the following:
    (1) A statement of the need for, and objectives of, the rule;
    (2) A statement of the significant issues raised by the public 
comments in response to the IRFA, a statement of the assessment of the 
agency of such issues, and a statement of any changes made in

[[Page 40092]]

the proposed rule as a result of such comments;
    (3) The response of the agency to any comments filed by the Chief 
Counsel for Advocacy of the Small Business Administration (SBA) in 
response to the proposed rule, and a detailed statement of any change 
made to the proposed rule in the final rule as a result of the 
comments;
    (4) A description of and an estimate of the number of small 
entities to which the rule will apply or an explanation of why no such 
estimate is available;
    (5) A description of the projected reporting, recordkeeping and 
other compliance requirements of the rule, including an estimate of the 
classes of small entities which will be subject to the requirement and 
the type of professional skills necessary for preparation of the report 
or record;
    (6) A description of the steps the agency has taken to minimize the 
significant economic impact on small entities consistent with the 
stated objectives of applicable statutes, including a statement of the 
factual, policy, and legal reasons for selecting the alternative 
adopted in the final rule and why each one of the other significant 
alternatives to the rule considered by the agency which affect the 
impact on small entities was rejected.
    Below is a discussion of the FRFA for each of these six elements:
    (1) A statement of the need for, and objectives of, the rule
    The need for Federal regulatory action is due to the risk of 
potential accidents caused by towing vessels on the nation's maritime 
system. The consequences of towing vessel accidents can be severe, 
including fatalities; injuries; damage to property, infrastructure and 
the environment; and closure of transportation assets and subsequent 
delays. There is also a public demand for improvements in the 
management of the nation's waterways.
    The casualties resulting from towing vessel accidents are examples 
of negative externalities that are relevant to this final rule. The 
cost of a higher safety standard is borne by the towing vessel owner or 
operator, while the cost of an accident could be distributed across 
various entities, including the vessel owner or operator, crew, other 
vessel owners or operators, federal, state, and local public service 
providers, businesses, and private citizens. The material failure of 
the private market in reaching the socially optimal outcome increases 
the risk to the public. An uncompensated increase in risk currently 
exists due to inconsistent safety practices in the marine towing 
industry. Regulatory action is required to take steps to reduce risk 
industry-wide and thereby obtain the socially optimal outcome.
    This final rule is authorized and made necessary by the 2004 Act, 
which made towing vessels subject to inspection. Further, the 2010 Act 
authorized the Secretary to issue a rule containing towing safety 
management system provisions promulgated under 46 U.S.C. 3306(j).
    The objective of this regulatory action is to enhance the safe 
operations of towing vessels on our nation's waterways. The final rule 
seeks to fulfill this objective by including towing vessels on the list 
of vessels that Coast Guard must inspect, improving the working 
environment of towing vessel crews, and placing responsibility for the 
safe operation of towing vessels on the owners or operators of the 
vessels. The requirements of the final rule are designed to encourage 
companies to engage at every level to improve safe operations, 
maintenance and design and adhere to prescribed safety standards.
    (2) A statement of the significant issues raised by the public 
comments in response to the initial regulatory flexibility analysis, a 
statement of the assessment of the agency of such issues, and a 
statement of any changes made in the proposed rule as a result of such 
comments
    On August 11, 2011, the Coast Guard published an NPRM titled 
``Inspection of Towing Vessels'' in the Federal Register (76 FR 49976). 
The Coast Guard then held four public meetings, one each in Newport 
News, VA; New Orleans, LA; St. Louis, MO; and Seattle, WA. We received 
and considered a combined total of more than 3,000 comments, from more 
than 265 written submissions and oral statements from 105 persons at 
public meetings, in developing this final rule. We summarized these 
comments in the ``Discussion of Comments and Changes'' section of the 
preamble for the final rule.
    We received several comments from small business owners and 
operators on the economic impact of subchapter M regulations. Some 
commenters were opposed to new regulations and did not provide specific 
information or data on how they will be impacted by its requirements. 
Many other commenters requested either exemption or grandfathering from 
all or some of these regulations. These commenters wanted to completely 
avoid or mitigate the impact of the regulations so they could continue 
to serve the towing vessel industry. Below is a discussion of comments 
received on small business impacts.
    Some commenters felt that subchapter M requirements would hurt 
small business owners and their employees, and could put many small 
entities out of business. However, they did not provide specific data 
on how much of a burden the requirements might be on their operational 
costs. The most specific comment received noted that recordkeeping 
proposals alone would require him to hire one or more new full time 
workers. Some other commenters pointed to the overall costs of 
subchapter M regulations that were previously put in a range of 
$100,000 to $250,000, per vessel, and potentially several million 
dollars per company for business entities that owned multiple towing 
vessels.
    Several other commenters, similar to the previous group of 
commenters also expressed concern that their company would not be able 
to pay for these requirements, and therefore, either be forced out of 
business or be acquired by larger entities in the towing vessel 
industry. Due to these costly subchapter M regulations one commenter 
argued that lenders would delay lending and review existing ship 
mortgages to reassess their collateral positions. This commenter noted 
that this is because many small towing vessel owners and operators 
could not afford to comply with the requirements of the regulations. 
Another commenter stated that his company would lose the ability to 
borrow against their boats if they can't comply with the proposed 
regulations. One commenter estimated that no less than 20 percent of 
the aggregate U.S. towing fleet would be put out of service, if the 
final rule goes into effect as written in the NPRM.
    The Coast Guard appreciates these comments on the economic impact 
of the final rule on small entities. Cognizant of regulatory impacts on 
small entities, the Coast Guard sought to minimize these impacts and 
has structured the final rule with this end in mind. The Coast Guard's 
efforts to minimize the cost impacts on small entities in the final 
rule include the following.
     Inspection compliance options: The Coast Guard has 
retained from the proposed rule flexibility in the method for complying 
with inspections, either through Coast Guard inspections or a TSMS. 
Some commenters suggested that a TSMS be mandatory for all towing 
owners and operators and their vessels. However, the Coast Guard has 
instead continued to allow either option, so that small entities can 
chose the approach

[[Page 40093]]

that minimizes impacts on their particular business operations.
     Automatic External Defibrillator (AED): The Coast Guard 
has removed the requirement for towing vessels to have AEDs to reduce 
the cost impact of the final rule. The savings resulting from this 
change would be estimated at $2,500 per unit for each vessel.
     Pilothouse alerters: The Coast Guard has retained the 
requirement for pilothouse alerters, but has limited applicability to 
larger towing vessels (in excess of 65 ft) with potentially higher risk 
profiles. To reduce the burden of this requirement, the Coast Guard has 
also allowed for a longer implementation period. For vessels less than 
65 feet, the savings are the $5,410 cost of the alerter per vessel.
     Equivalence of existing SMSs: For owners and operators 
that choose the TSMS option, the Coast Guard has sought to minimize 
additional effort to develop and implement a TSMS by establishing a 
process for granting equivalency between an existing SMS and a TSMS. 
Also, under the final rule, compliance with ISM is equivalent to a 
TSMS. This change has the potential to minimize efforts for the 51 
percent of the affected population covered by an existing SMS, but the 
amount of the savings has not been quantified.
     Removing certain requirements for existing vessels: In 
response to comments received on the NPRM, the Coast Guard has removed 
certain requirements in parts 143 and 144 for existing vessels to 
decrease the cost. In the NPRM, the Coast Guard estimated that certain 
requirements could cost in the range of $5,000 to $20,000 per 
requirement per vessel, at a total of approximately $60,000 per vessel. 
Commenters provided estimates at or exceeding $100,000 to $150,000 to 
retrofit vessels to meet these requirements.
     Stability documents: The Coast Guard has changed certain 
requirements in part 144 to offer additional methods for compliance. 
One commenter estimated that it could cost tens of thousands of dollars 
to have a naval architect generate stability calculations under the 
NPRM proposal. Section 144.300(b) now offers three options for an 
existing vessel without a stability document to meet part 144 
requirements: Findings based on the vessel's operation or a history of 
satisfactory service, successful performance on operational tests, or a 
satisfactory stability assessment. In particular, allowing for a 
vessel's history of satisfactory service in the final rule provides a 
lower cost method for compliance, which should serve to reduce the cost 
on small entities.
    (3) The response of the agency to any comments filed by the Chief 
Counsel for Advocacy of the Small Business Administration in response 
to the proposed rule, and a detailed statement of any change made to 
the proposed rule in the final rule as a result of the comments
    The Coast Guard did not receive any comments from the SBA's Office 
of Advocacy regarding the impact that the proposed rule would have on 
small entities.
    (4) A description of and an estimate of the number of small 
entities to which the rule will apply or an explanation of why no such 
estimate is available
    The final rule will affect the owners and operators of certain 
towing vessels. We constructed a towing vessel fleet database based on 
data from the Waterborne Transportation Lines of the U.S., U.S. Army 
Corps of Engineers; the Inland River Record, Waterways Journal; the 
Coast Guard's MISLE system; Web sites and other public sources. From 
this database we identified 5,509 vessels affected by this rule. There 
are 1,096 companies that own or operate these vessels.
    We used available operator name and address information to research 
public and proprietary databases for entity type (subsidiary or parent 
company), primary line of business, employee size, revenue, and other 
information. We found 20 vessels owned by 17 governments and 6 owned by 
non-profits. The remainder are business entities. For governmental 
jurisdictions, we determined whether the jurisdiction had populations 
of less than 50,000 as per the criteria in the RFA. For nonprofits, we 
qualitatively evaluated whether the nonprofit was independently owned 
and operated and is not dominant in its field. For the businesses, we 
matched the owner information to the SBA's ``Table of Small Business 
Size Standards'' to determine if an entity is small in its primary line 
of business as classified in the North American Industry Classification 
System (NAICS). Of the 20 vessels owned by 13 governments, 5 are owned 
by small government jurisdictions (with fewer than 50,000 people). Of 
the 6 vessels owned by 3 non-profits, all are owned by non-profits that 
are independently operated and not dominant in their field.
    There are a total of 26 NAICS-coded industries in the final rule's 
affected population and we show below the 11 industries that appeared 
most frequently in the affected population of owners or operators of 
towing vessels.

    We randomly selected a sample size of the 5,509 towing vessels to 
reach the 95 percent confidence level. This sample produced a set of 
223 businesses that own and operate the towing vessels. No governments 
or non-profits were in our sample. Of the 223 businesses, there were 43 
companies that exceeded SBA small business size standards, 113 
companies considered small by the SBA, and 67 companies for which no 
information was available. For the purposes of this analysis, we 
consider all entities for which information was not available to be 
small. Thus, there are 180 businesses in our sample we consider to be 
small entities.
Cost Methodology--Analysis Periods, Variable Costs, and Fixed Costs
    The cost incurred by a particular small entity over the 10-year 
period of analysis varies based on the period of years in question. For 
the purposes of this FRFA, we analyzed the cost impacts on small 
entities for a representative year within two periods, as the phase-in 
period of the initial two years and the full implementation period from 
Years 3 through 10 have unique costs. During the phase-in period, 
companies will face initial implementation costs, such as the TSMS and 
conducting initial vessel surveys. Over the following full 
implementation period, companies will face ongoing costs associated 
with periodic surveys, vessels will operate under their COIs and 
companies will face ongoing costs associated with obtaining and 
renewing COIs, periodic surveys and audits, drydock inspections, and 
Coast Guard inspections. The scheduling of all these activities are 
dependent on a number of factors, such as the following:
     A vessel operating under the TSMS option will be subject 
to management and vessel audits and the operating company will need to 
obtain a TSMS Certificate.
     Many of the requirements are based on when a vessel 
obtains its first COI, which lasts for five years. The rule states that 
vessel owners/operators must spread out the initial COI over two-to-
four years, depending on the size of the fleet.
     A vessel operating in salt water must have two drydock 
inspections in every 5-year period, while one operating in fresh water 
only needs one.
    We anticipate that the entities will manage the compliance 
activities so that costs are efficiently managed. For example, an owner 
with vessels operating under the TSMS options having a fleet of vessels 
in the upper Mississippi River may want to have the Coast Guard inspect 
all vessels at one time during the winter when that stretch of the 
River is closed and the vessels are idle. As a counter example, and 
entity with a fleet in constant operation may want to spread the Coast 
Guard inspections over the five-year period to minimize disruptions to 
service. Thus, there is no one year in the full implementation period 
that contains all the cost elements for all vessels. To provide a 
single reference year we constructed a hypothetical ``heavy load'' year 
that contains all the requirements for a vessel and an entity. This 
year includes a COI renewal for a TSMS vessel, the Coast Guard 
inspection, and a drydock inspection and other costs that apply 
throughout this period. As described below, the construct of the 
``heavy load year'' enabled the comparison of the costs for one year to 
revenue for one year.
    To conduct the small entity revenue impact analysis we divided the 
total annual costs of an entity for the two periods into these three 
components: vessel annual variable costs, vessel annual fixed costs, 
and unit annual entity costs. Vessel annual variable costs are those 
that are dependent upon the characteristics or condition of the vessel. 
Vessel annual fixed costs are those that apply to all vessels, such as 
the requirement to post the COI. Unit annual entity costs are those 
that accrue at the management level of the entity. The annual costs for 
an entity are calculated for the phase-in and full implementation 
periods using the following equations:
    Equation 1: Vessel Annual Unit Cost = Vessel Annual Variable Cost + 
Vessel Annual Fixed Cost
    Equation 2: Total Annual Vessel Costs = Vessel Annual Unit Cost 
(eq. 1) * number of vessels
    Equation 3: Total Entity Costs = Total Annual Vessel Costs (eq. 2) 
+ Unit Annual Entity Costs
    Vessel annual fixed costs and unit annual entity costs are derived 
for the phase-in and full-implementation periods from data in the cost 
model from the regulatory analysis. The fixed costs for the phase-in 
period are the same in both years. For the full-implementation period 
we used the costs associated with the hypothetical ``heavy load'' year, 
described above. Table 18 shows these costs for the two periods.

                     and Full-Implementation Periods

    In the regulatory analysis, we used MISLE deficiency data to 
estimate the number of vessels that would need to make changes to 
comply with various system or equipment standards. This generated 
population based estimates, but did not identify the specific vessels 
that would incur these compliance costs.
    To estimate vessel variable costs, we adopted the Monte Carlo 
methodology used in the IRFA. We used the Monte Carlo as a tool to 
resolve the uncertainties related to which vessels will need to comply 
with which requirements, each with their own unit costs and affected 
populations. The Monte Carlo model we developed accounts for the ranges 
of unit costs and affected populations across the requirements by 
taking as inputs the specific unit costs and affected populations for 
each requirement. The output of the model is a distribution of total 
variable costs.
    The Monte Carlo model simulated a one-year variable costs for the 
phase-in and full-implementation periods separately. The inputs are 
from the cost estimates of each requirement: The affected population 
recast as a percentage of the total vessel population, and the unit 
costs. Each simulation was run 10,000 times to produce a distribution 
of costs. For a point estimate of the vessel annual variable costs we 
took the average value of each distribution, which yielded $4,787 for 
the phase-in period and $9,866 for the full implementation period.
    To summarize from the presentations above, the parameters for the 
phase-in period are the following:

Vessel Annual Variable Cost = $4,787
Vessel Annual Fixed Cost = $11,480
Entity Annual UnitCost = $5,045.

    Applying Equation 1 from above, Vessel Annual Unit Cost = $16,267 
(Vessel Annual Variable Cost, $4,787, + Vessel Annual Fixed Cost, 
$11,480).
    The variable inputs are the number of vessels operated by each 
entity, which is found in the Affected Population Database, and the 
entity's revenue.

[[Page 40095]]

    We developed an annual revenue impact analysis for the average 
company in our sample. The average number of vessels per company in our 
sample is 1.7, so the two-vessel example is representative of an 
average company. We estimate this average two-vessel owning small 
entity will incur an annual cost of $37,579 during the two-year phase-
in period of this rule. Consequently, the total two-year implementation 
cost for the average small entity is estimated at $75,158. The average 
annual revenue across the sample is $10,058,187. With these inputs we 
derived an estimate of the annual revenue impact for the average entity 
in the sample. The results of this analysis are shown as Example 1 in 
Table 19. Examples 2 through 4 show the calculations for examples of 
applying Equations 2 and 3 for three hypothetical companies, with one-, 
three-, and four-vessel fleets, respectively.

    For the 92 businesses with revenue data, we calculated the total 
costs for each small entity and a revenue impact as a percentage of 
revenue. Table 21 presents the annual revenue impact on small entities 
for the phase-in and full implementation periods.

----------------------------------------------------------------------------------------------------------------

    During the phase-in period, for the average cost per year, our 
analysis indicates that nearly 65 percent of the small entities will 
have an annual revenue impact of 1% or less. Approximately 28.3 percent 
of the small entities will have an annual revenue impact of between 3 
percent and 10 percent. The remaining 6.5 percent of the small entities 
will have an annual revenue impact of over 10 percent.
    After full implementation of inspections and COIs, we estimate that 
47.8 percent of the small entities will have an annual revenue impact 
of 1% or less. Approximately 40.2 percent of the small entities will 
have an annual revenue impact of between 3 percent and 10 percent. The 
remaining 12.0 percent of the small entities will have an annual 
revenue impact of over 10 percent.
    (5) A description of the projected reporting, recordkeeping and 
other compliance requirements of the rule, including an estimate of the 
classes of small entities which will be subject to the requirement and 
the type of professional skills necessary for preparation of the report 
or record
    Under the provisions of the final rule, 5,509 towing vessels owned 
by 1,096 towing vessel companies will be required to conduct a variety 
of reporting and recordkeeping activities, related to obtaining and 
renewing a COI, which will involve compiling information, submission, 
and third part review. Additionally, information will be collected at 
the vessel and company level regarding safety, operations, drills, 
record keeping, and general compliance. These requirements will be 
added as a new collection of information with the OMB control number 
1625-0117 with the title ``Towing Vessels--Title 46 CFR Subchapter M. 
Please refer to Chapter 11, ``Paperwork Reduction Act'', the Regulatory 
Analysis for further detail.
    (6) A description of the steps the agency has taken to minimize the 
significant economic impact on small entities consistent with the 
stated objectives of applicable statutes,

[[Page 40096]]

including a statement of the factual, policy, and legal reasons for 
selecting the alternative adopted in the final rule and why each one of 
the other significant alternatives to the rule considered by the agency 
which affect the impact on small entities was rejected
    Prior to this rulemaking, the Coast Guard participated in the TSAC 
meetings that helped formulate our proposals in the NPRM. Small 
entities had the opportunity to participate in this Committee and the 
Economic Analysis Working Group.
    The Coast Guard has made a number of changes from the proposals in 
the NPRM after consideration of public comments. A full discussion of 
comments and Coast Guard responses is found in the ``Discussion of 
Comments and Changes'' section above. In developing both the original 
proposal and the final rule, the following are examples of the Coast 
Guard's efforts to minimize the economic impact on small entities.
    Inspection compliance options: The Coast Guard has retained from 
the proposal the choice of method for complying with inspections, 
either through Coast Guard inspections or a TSMS. Some commenters 
suggested that a TSMS be mandatory for all towing owners and operators 
and their vessels. However, the Coast Guard has instead continued to 
allow either option, so that small entities can choose the approach 
that minimizes impacts on their particular business operations.
    AED: The Coast Guard has removed the requirement for towing vessels 
to have AEDs to reduce the cost impact of the final rule.
    Pilothouse alerters: The Coast Guard has retained the requirement 
for pilothouse alerters, but has limited applicability to larger towing 
vessels (in excess of 65 ft) with potentially higher risk profiles. To 
reduce burden of this requirement the Coast Guard has also allowed for 
a longer implementation period.
    Equivalence of existing SMSs: For owners and operators that chose 
the TSMS option, Coast Guard has sought to minimize effort to develop 
and implement a TSMS by establishing a process for granting equivalency 
between an existing SMS and a TSMS. Also, under the final rule, 
compliance with ISM is equivalent to a TSMS.
    Removing certain requirements for existing vessels: In response to 
comments received on the NPRM, the Coast Guard has removed certain 
requirements in parts 143 and 144 for existing vessels to decrease the 
cost.
    Stability documents: The Coast Guard has changed certain 
requirements in part 144 to offer additional methods for compliance. 
Section 144.300(b) now offers three options for an existing vessel 
without a stability document to meet part 144 requirements: Findings 
based on the vessel's operation or a history of satisfactory service, 
successful performance on operational tests, or a satisfactory 
stability assessment. In particular, allowing for a vessel's history of 
satisfactory service in the final rule provides a lower cost method for 
compliance, which should serve of compliance to reduce the cost on 
small entities.
    The Coast Guard discusses the full range of alternatives considered 
in Section 6 of the RA. We monetized the impacts of three alternatives. 
Table 13 above summarizes the costs, benefits and net benefits of the 
alternatives considered and the preferred alternative adopted in the 
final rule.
    Alternative 1 estimates impacts of only implementing the inspection 
requirements of the final rule, without the operational, lifesaving, 
fire protection, machinery and electrical, and construction and 
arrangement requirements. Although this approach reduces the cost 
impacts of the final rule, the benefits fall by almost 85 percent. The 
annualized net impact of the rule (benefits minus costs) falls from 
$4.5 million in net benefits for the preferred alternative to a net 
cost of $21.2 million. Requiring only the inspection requirements 
without also increasing the standards in the other CFR parts fails to 
meet the objective of improving towing vessel safety and decreasing the 
risk of towing vessel accidents to a substantive degree. The Coast 
Guard developed and chose the comprehensive approach that combines an 
inspection regime with improved standards as it results in the greater 
societal outcomes, as demonstrated by the net benefits.
    Similarly, Alternative 2, which estimates the impact of delaying 
implementation of the operational standards found in Part 140, also 
results in lower annualized net impacts: $4.5 million net benefits for 
the preferred alternative and $17.1 million net costs for Alternative 
2. The Coast Guard chose not to delay implementation of the operational 
standards in part 140 as it results in the greater societal outcomes, 
as demonstrated by the net benefits.
    Alternative 3 analyzes the impacts of not removing certain 
requirements in parts 143 and 144 (as discussed above). Alternative 3 
has a greater cost burden, including greater impact on small entities, 
than the preferred alternative and results in net costs of $26.4 
million. For these reasons, the Coast Guard has applied the certain 
requirements in parts 143 and 144 to only new vessels and reduced the 
burden on small entities.
    We are interested in the potential impacts from this final rule on 
small businesses and we request public comment on these potential 
impacts.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we want to assist small 
entities in understanding this final rule so that they can better 
evaluate its effects on them and participate in the rulemaking. As 
noted, we have prepared a Small Entities Guide for this rule and have 
placed in it the docket for this rulemaking. If the final rule would 
affect your small business, organization, or governmental jurisdiction 
and you have questions concerning its provisions or options for 
compliance, please consult LCDR Will Nabach, Project Manager, CG-OES-2, 
Coast Guard, telephone 202-372-1386. The Coast Guard will not retaliate 
against small entities that question or complain about this rule or any 
policy or action of the Coast Guard.
    Small businesses may send comments on the actions of Federal 
employees who enforce, or otherwise determine compliance with, Federal 
regulations to the Small Business and Agriculture Regulatory 
Enforcement Ombudsman and the Regional Small Business Regulatory 
Fairness Boards. The Ombudsman evaluates these actions annually and 
rates each agency's responsiveness to small business. If you wish to 
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR 
(1-888-734-3247).

D. Collection of Information

    This final rule would call for a collection of information under 
the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). As defined 
in 5 CFR 1320.3(c), ``Collection of Information'' comprises reporting, 
recordkeeping, monitoring, posting, labeling, and other, similar 
actions. The title and description of the information collections, a 
description of those who must collect the information, and an estimate 
of the total annual burden follow. The estimate covers the time for 
reviewing instructions, searching existing sources of data, gathering 
and maintaining the data needed, and completing and reviewing the 
collection.
    Title: Towing Vessels--Title 46 CFR Subchapter M.

[[Page 40097]]

    Summary of the Collection of Information: Owners and managing 
operators of inspected towing vessels would be required to either 
develop and maintain documentation for their safety management system 
and arrange periodic audits and surveys through third-party 
organizations, or to demonstrate compliance with the subchapter M to 
Coast Guard inspectors. Additional documentation would be required to 
obtain a Certificate of Inspection for each vessel, comply with crew 
and vessel operational safety standards, vessel equipment and system 
standards, procedures and schedules for routine tests and inspections 
of towing vessels and their onboard equipment and systems. The new 
requirements for third-party auditors and surveyors include obtaining 
Coast Guard approval and renewing it periodically. The Coast Guard 
would be burdened by reviewing required reports, conducting compliance 
examinations of towing vessels and overseeing third-party auditors and 
surveyors through approval and observation.
    Need for Information: The information is necessary for the proper 
administration and enforcement of the towing vessel inspection program.
    Proposed use of Information: The Coast Guard would use this 
information to document that towing vessels meet inspection 
requirements of subchapter M.
    Description of the Respondents: The respondents are the owners and 
managing operators of towing vessels and third-party auditors and 
surveyors that would be required to complete various forms, reports and 
keep reports.
    Number of Respondents: The 5,694 respondents are the owners and 
operators of 5,509 affected towing vessels and 185 entities that employ 
the third-party auditors and surveyors.
    Frequency of Response: The average responses per year are 
7,660,257.
    Estimate of Total Annual Burden: The total annual burden is 181,669 
hours.
    As required by the Paperwork Reduction Act of 1995 (44 U.S.C. 
3507(d)), we have submitted a copy of this rule to the Office of 
Management and Budget (OMB) for its review of the collection of 
information.
    You need not respond to a collection of information unless it 
displays a currently valid control number from OMB. Before the Coast 
Guard could enforce the collection of information requirements in this 
rule, OMB would need to approve the Coast Guard's request to collect 
this information.

E. Federalism

    A rule has implications for federalism under Executive Order 13132, 
Federalism, if it has a substantial direct effect on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. We have analyzed this rule under that order and have 
determined that it is consistent with the fundamental federalism 
principles and preemption requirements described in E.O. 13132. Our 
analysis is explained below.
    It is well settled that States may not regulate in categories 
reserved for regulation by the Coast Guard. It is also well settled 
that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 
8101 (design, construction, alteration, repair, maintenance, operation, 
equipping, personnel qualification, and manning of vessels), as well as 
the reporting of casualties and any other category in which Congress 
intended the Coast Guard to be the sole source of a vessel's 
obligations, are within the field foreclosed from regulation by the 
States. (See the decision of the Supreme Court in the consolidated 
cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 
120 S.Ct. 1135 (March 6, 2000)). This rule covers all of the foreclosed 
categories, as it establishes regulations covering a new category of 
inspected vessels, as mandated by Congress. Because the States are now 
foreclosed from regulating towing vessels in these categories, the rule 
is consistent with the principles of federalism and preemption 
requirements in Executive Order 13132.

F. Unfunded Mandates Reform Act

    The Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1531-1538, 
requires Federal agencies to assess the effects of their discretionary 
regulatory actions. In particular, the Act addresses actions that may 
result in the expenditure by a State, local, or tribal government, in 
the aggregate, or by the private sector of $100,000,000 (adjusted for 
inflation) or more in any one year. Though this rule will not result in 
such an expenditure, we do discuss the effects of this rule elsewhere 
in this preamble.

G. Taking of Private Property

    This rule will not cause a taking of private property or otherwise 
have taking implications under E.O. 12630, Governmental Actions and 
Interference with Constitutionally Protected Property Rights.

H. Civil Justice Reform

    This rule meets applicable standards in sections 3(a) and 3(b)(2) 
of E.O. 12988 (``Civil Justice Reform''), to minimize litigation, 
eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this rule under E.O. 13045 (``Protection of 
Children from Environmental Health Risks and Safety Risks''). This rule 
is not an economically significant rule and would not create an 
environmental risk to health or risk to safety that might 
disproportionately affect children.

J. Indian Tribal Governments

    This rule does not have tribal implications under E.O. 13175 
(``Consultation and Coordination with Indian Tribal Governments''), 
because it would not have a substantial direct effect on one or more 
Indian tribes, on the relationship between the Federal Government and 
Indian tribes, or on the distribution of power and responsibilities 
between the Federal Government and Indian tribes.

K. Energy Effects

    We have analyzed this rule under E.O. 13211 (``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use''). We have determined that it is not a ``significant energy 
action'' under E.O. 13211, because although it is a ``significant 
regulatory action'' under E.O. 12866, it is not likely to have a 
significant adverse effect on the supply, distribution, or use of 
energy, and the Administrator of OMB's Office of Information and 
Regulatory Affairs has not designated it as a significant energy 
action.

L. Technical Standards and 1 CFR Part 51

    The National Technology Transfer and Advancement Act, codified as a 
note to 15 U.S.C. 272, directs agencies to use voluntary consensus 
standards in their regulatory activities unless the agency provides 
Congress, through OMB, with an explanation of why using these standards 
would be inconsistent with applicable law or otherwise impractical. 
Voluntary consensus standards are technical standards (e.g., 
specifications of materials, performance, design, or operation; test 
methods; sampling procedures; and related management systems practices) 
that are developed or adopted by voluntary consensus standards bodies.
    This final rule uses the following voluntary consensus standards 
from:


[[Page 40098]]


The American Boat and Yacht Council (ABYC)--
     ABYC E-11 (2003), AC and DC Electrical Systems on Boats. 
This standard covers the design, construction, and installation of 
direct current (DC) electrical systems on boats and of alternating 
current (AC) electrical systems on boats. ABYC H-2 (2000), Ventilation 
of Boats Using Gasoline. This standard covers the design, construction,

regulations concerning the training of maritime personnel; regulations 
concerning manning, documentation, inspection and equipping of vessels; 
regulations concerning equipment approval and carriage requirements; 
regulations concerning vessel operation safety standards; and 
Congressionally mandated regulations designed to improve or protect the 
environment. This action falls under section 2.B.2, figure 2-1, 
paragraphs (34)(a), (c), (d), and (e) of the Commandant Instruction 
M16475.lD, and under section 6(a) and (b) of the ``Appendix to National

Sec.  136.115  Equivalents.

    (a) The Coast Guard may approve any arrangement, fitting, 
appliance, apparatus, equipment, calculation, information, or test that 
provides a level of safety equivalent to that established by any 
specific provision of this subchapter. Submit requests for approval to 
the Coast Guard via the cognizant OCMI. The Marine Safety Center may 
require engineering evaluations and tests to verify the equivalence.
    (b) The Coast Guard may accept compliance with the provisions of 
SOLAS applicable to the vessel's size and route (incorporated by 
reference, see Sec.  136.112), as an equivalent to specific 
requirements of this subchapter. Submit requests for a determination of 
equivalency for a particular vessel to the Coast Guard via the 
cognizant OCMI.
    (c) Alternative compliance arrangement provisions related to SMSs 
are contained in Sec.  138.225 of this subchapter.
    (d) Alternate compliance arrangements must be documented within the 
TSMS applicable to the vessel.


Sec.  136.120  Special consideration.

    Based on a review of relevant information and on the TSMS 
applicable to the vessel, the cognizant OCMI who issues the COI may 
give special consideration to authorizing departures from specific 
requirements, when unusual circumstances or arrangements warrant such 
departures and when an equivalent level of safety is provided.


Sec.  136.130  Options for documenting compliance to obtain a 
Certificate of Inspection.

    (a) There are two options for documenting compliance with the 
requirements in this subchapter to obtain a COI:
    (1) The Coast Guard option, in which all inspections of the towing 
vessel are conducted by the Coast Guard, as discussed in Sec.  136.210 
and parts 137 and 140 through 144 of this subchapter; or
    (2) The TSMS option, as discussed in Sec.  136.210, and in parts 
137 through 144 of this subchapter.
    (b) Regardless of the option chosen, the Coast Guard is responsible 
for issuing a towing vessel COI, and may board a vessel at any time to 
verify compliance and take appropriate action.
    (c) An owner or managing operator choosing the Coast Guard option 
may use a management system, vessel operations manual, towing vessel 
record (TVR), or logbook to meet this subchapter's recordkeeping 
requirements.
    (d) When submitting an application for inspection, the owner or 
managing operator must specify on the application which option he or 
she chooses for each particular towing vessel. Owners or managing 
operators may choose different options for the individual vessels 
within their fleets.
    (e) Requests to change options during the period of validity of an 
existing COI must be accompanied by an application to the OCMI for a 
new COI. If the requirements for the new option are met, the OCMI will 
issue the vessel a new COI.


Sec.  136.172  Temporary compliance for existing towing vessels.

    An existing towing vessel subject to this subchapter will remain 
subject to Coast Guard regulations applicable to the vessel on July 19, 
2016 until either July 20, 2018 or the date the vessel obtains a COI, 
whichever date is earlier.


Sec.  136.175  Approved equipment.

    Where equipment in this subchapter is required to be of an approved 
type, such equipment requires the specific approval of the Coast Guard. 
A list of approved equipment and materials may be found online at 
http://cgmix.uscg.mil/Equipment/EquipmentSearch.aspx. Any OCMI may be 
contacted for information concerning approved equipment and materials.


Sec.  136.180  Appeals.

    Any person directly affected by a decision or action taken under 
this subchapter, by or on behalf of the Coast Guard, may appeal in 
accordance with 46 CFR 1.03.

Subpart B--Certificate of Inspection


Sec.  136.200  Certificate required.

    (a) A towing vessel may not be operated without having onboard a 
valid COI issued by the Coast Guard as required by Sec.  136.202.
    (b) Each towing vessel certificated under the provisions of this 
subchapter must be in full compliance with the terms of the COI.
    (c) If necessary to prevent the delay of the vessel, the Coast 
Guard may issue a temporary COI to a towing vessel, pending the 
issuance and delivery of the permanent COI. The temporary COI

[[Page 40107]]

must be carried in the same manner as the regular COI and is equivalent 
to the permanent COI that it represents.
    (d) A towing vessel on a foreign voyage between a port in the 
United States and a port in a foreign country whose COI expires during 
the voyage may lawfully complete the voyage without a valid COI, 
provided the voyage is completed within 30 days of expiration, and 
provided that the COI did not expire within 15 days of sailing on the 
foreign voyage from a U.S. port.


Sec.  136.202  Certificate of Inspection phase-in period.

    (a) All owners or managing operators of more than one existing 
towing vessel required to have a COI by this subchapter must ensure 
that each existing towing vessel under their ownership or control is

    (c) A new towing vessel must obtain a COI before it enters into 
service.


Sec.  136.205  Description.

    A towing vessel's COI describes the vessel, routes that it may 
travel, minimum manning requirements and total persons allowed onboard, 
safety equipment and appliances required to be onboard, horsepower, and 
other information pertinent to the vessel's operations as determined by 
the OCMI.


Sec.  136.210  Obtaining or renewing a COI.

    Owners and managing operators must submit Form CG-3752, 
``Application for Inspection of U.S. Vessel,'' to the cognizant OCMI 
where the inspection will take place. The owner or managing operator 
must submit the application at least 30 days before the vessel will 
undergo the initial inspection for certification. The owner or managing 
operator must schedule an inspection for this initial certification 
with the cognizant OCMI at least 3 months before the vessel is to 
undergo the inspection for certification.
    (a) In addition to Form CG-3752, the owner or managing operator 
must submit:
    (1) For initial certification:
    (i) Vessel particular information; and
    (ii) Number of persons in addition to the crew, if requested; or
    (2) For a renewal of certification:
    (i) Any changes to the information in paragraph (a)(1) of this 
section; and
    (ii) A description of any modifications to the vessel.
    (b) In addition to Form CG-3752 and the requirements of paragraph 
(a) of this section, the owner or managing operator of vessels 
utilizing the TSMS option must submit:
    (1) Objective evidence that the owner or managing operator and the 
vessel are in compliance with the TSMS requirements in part 138 of this 
subchapter; and
    (2) Objective evidence that the vessel's structure, stability, and 
essential systems comply with the applicable requirements of this 
subchapter for the intended route and service. This objective evidence 
may be in the form of a survey report issued by a TPO or another form 
acceptable to the Coast Guard.


Sec.  136.212  Inspection for certification.

    (a) Frequency of inspections. After a towing vessel receives its 
initial COI, the OCMI will inspect a towing vessel subject to this 
subchapter located in his or her jurisdiction at least once every 5 
years. The OCMI must ensure that every towing vessel is of a structure 
suitable for its intended route. If the OCMI deems it necessary, he or 
she may direct the vessel to get underway, and may adopt any other 
suitable means to test the towing vessel and its equipment.
    (b) Nature of inspection. The inspection will ensure that the 
vessel is in satisfactory condition and fit for the service for which 
it is intended, and that it complies with the applicable statutes and 
regulations for such vessels. The inspection will include inspections 
of the structure, pressure vessels and their appurtenances, piping, 
main and auxiliary machinery, electrical installations, lifesaving 
appliances, fire detecting and extinguishing equipment, pilot boarding 
equipment, and other equipment. The inspection will also determine that 
the vessel is in possession of any valid certificates or licenses 
issued by the Federal Communications Commission, if required. The 
inspection will also include an examination of the vessel's lights, 
means of making sound signals and distress signals, and pollution 
prevention systems and procedures.
    (c) Time of issuance of COI. The OCMI will issue a vessel a new COI 
after the vessel successfully completes the inspection for 
certification.


Sec.  136.215  Period of validity.

    (a) A COI for a towing vessel is valid for 5 years from the date of 
issue.
    (b) For a towing vessel utilizing the TSMS option, the COI is 
invalid upon the expiration or revocation of the owner or managing 
operator TSMS certificate or the ISM Code Certificate.
    (c) A COI may be suspended and withdrawn or revoked by the 
cognizant Officer in Charge, Marine Inspection at any time for 
noncompliance with the requirements of this subchapter.


Sec.  136.220  Posting.

    (a) The original COI must be framed under glass or other 
transparent material and posted in a conspicuous place onboard the 
towing vessel.
    (b) If posting is impracticable, the COI must be kept on board in a 
weathertight container and must be readily available.


Sec.  136.230  Routes permitted.

    (a) The area of operation for each towing vessel and any necessary 
operational limits are determined by the cognizant OCMI and recorded on 
the vessel's COI. Each area of operation, referred to as a route, is 
described on the COI under the major headings ``Oceans,'' 
``Coastwise,'' ``Limited Coastwise,'' ``Great Lakes,'' ``Lakes, Bays, 
and Sounds,'' or ``Rivers,'' as applicable. Additional limitations 
imposed or extensions granted are described by reference to bodies of 
waters, geographical points, distances from geographical points, 
distances from land, depths of channel, seasonal limitations, and 
similar factors.
    (b) Operation of a towing vessel on a route of lesser severity than 
those specifically described or designated on the COI is permitted, 
unless the route is expressly prohibited on the COI. The general order 
of decreasing severity of routes is: Oceans; coastwise; limited 
coastwise; Great Lakes; lakes, bays, and sounds; and rivers. The 
cognizant OCMI may prohibit a vessel from operating on a route of 
lesser severity than the primary route on which a vessel is authorized 
to operate, if local conditions necessitate such a restriction.
    (c) When designating a permitted route or imposing any operational 
limits on a towing vessel, the cognizant OCMI may consider:
    (1) The route-specific requirements of this subchapter;
    (2) The performance capabilities of the vessel based on design, 
scantlings, stability, subdivision, propulsion,

[[Page 40108]]

speed, operating modes, maneuverability, and other characteristics;
    (3) The suitability of the vessel for nighttime operations and use 
in all weather conditions;
    (4) Vessel operations in globally remote areas or severe 
environments not covered by this subchapter. Such areas may include, 
but are not limited to, polar regions, remote islands, areas of extreme 
weather, or other remote areas where timely emergency assistance cannot 
be anticipated; and
    (5) The TSMS applicable to the vessel, if the vessel has one.


Sec.  136.235  Certificate of Inspection amendment.

    (a) An amended COI may be issued at any time by the cognizant OCMI. 
The amended COI replaces the original, but the expiration date remains 
the same as that of the original. An amended COI may be issued to 
authorize and record a change in the dimensions, gross tonnage, owner, 
managing operator, manning, persons permitted, route permitted, 
conditions of operations, or equipment of a towing vessel, from that 
specified in the current COI.
    (b) The owner or managing operator of the towing vessel must make a 
request for an amended COI to the cognizant OCMI any time there is a 
change in the character of the vessel or in its route, equipment, 
ownership, operation, or similar factors specified in its current COI. 
The OCMI may need to conduct an inspection before issuing an amended 
COI.
    (c) For those vessels selecting the TSMS option, the owner or 
managing operator of the towing vessel must provide to the OCMI 
objective evidence of compliance with the requirements in this 
subchapter prior to the issuance of an amended COI. The evidence must:
    (1) Be from a TPO and prepared in accordance with parts 138 and 139 
of this subchapter; and
    (2) Consider the change in the character of a vessel or in its 
route, equipment, ownership, operation, or similar factors specified in 
the vessel's current COI.


Sec.  136.240  Permit to proceed.

    Permission to proceed to another port for repairs (Form CG-948) may 
be required for a towing vessel that is no longer in compliance with 
its COI. This permission may be necessary in certain situations, 
including damage to the vessel, failure of an essential system, or 
failure to comply with a regulation, including failure to comply with 
the TSMS requirements, if appropriate.
    (a) What a vessel with a TSMS must do before proceeding to another 
port for repairs. A vessel with a TSMS may proceed to another port for 
repair, if:
    (1) In the judgment of the owner, managing operator, or master, the 
trip can be completed safely;
    (2) The TSMS addresses the condition of the vessel that has 
resulted in non-compliance and the necessary conditions under which the 
vessel may safely proceed to another port for repair;
    (3) The vessel proceeds as provided in the TSMS and does not tow 
while proceeding, unless the owner or managing operator determines that 
it is safe to do so; and
    (4) The owner or managing operator notifies the cognizant OCMI in 
whose zone the non-compliance occurred or is discovered, before the 
vessel proceeds. The owner or operator must also notify the cognizant 
OCMI in any other OCMI zones through which the vessel will transit.
    (b) What another vessel must do before proceeding to another port 
for repairs. If a vessel does not have a TSMS, or a vessel has one but 
it does not address the condition of the vessel that has resulted in 
non-compliance or the necessary conditions under which the vessel may 
safely proceed to another port for repair, the owner, managing 
operator, or master must request permission to proceed from the 
cognizant OCMI in whose zone the non-compliance occurs or is 
discovered. This permission operates as follows:
    (1) The request for permission to proceed may be made 
electronically, in writing, or orally. The cognizant OCMI may require a 
written description, a damage survey, or other documentation to assist 
in determining the nature and seriousness of the non-compliance.
    (2) The vessel will not engage in towing, unless the cognizant OCMI 
determines it is safe to do so.
    (3) The Coast Guard may issue the permit either on Form CG-948, 
``Permit to Proceed to Another Port for Repairs,'' or in letter form, 
and will state the conditions under which the vessel may proceed to 
another port for repair.
    (c) Inspection or examination. The cognizant OCMI may require an 
inspection of the vessel by a Coast Guard Marine Inspector or an 
examination by a surveyor from a TPO prior to the vessel proceeding.


Sec.  136.245  Permit to carry excursion party or temporary extension 
or alteration of route.

    (a) A towing vessel must obtain approval to engage in an excursion 
prior to carrying a greater number of persons than permitted by the 
COI, or to temporarily extend or alter its area of operation.
    (b) For a vessel utilizing the TSMS option, the vessel may engage 
in an excursion, if:
    (1) In the opinion of the owner, managing operator, or master the 
operation can be undertaken safely;
    (2) The TSMS addresses the temporary excursion operation 
contemplated; the necessary conditions under which the vessel may 
safely conduct the operation, including the number of persons the 
vessel may carry; the crew required; and any additional lifesaving or 
safety equipment required;
    (3) The vessel proceeds as provided in the TSMS; and
    (4) The owner, managing operator, or master notifies the cognizant 
OCMI at least 48 hours prior to the temporary excursion operation. The 
cognizant OCMI may require submission of pertinent provisions of the 
TSMS applicable to the vessel for review and onboard verification of 
compliance. If the cognizant OCMI has reasonable cause to believe that 
the TSMS applicable to the vessel is insufficient for the intended 
excursion, additional information may be requested and/or additional 
requirements may be imposed.
    (c) If the towing vessel is not under a TSMS, or the TSMS 
applicable to the vessel does not address the temporary excursion 
operation:
    (1) The owner or managing operator must submit an application to 
the cognizant OCMI. The application must state the intended route, 
number of passengers or guests, and any other conditions applicable to 
the excursion that exceed those specified in its COI.
    (2) The cognizant OCMI may issue the permit either on Form CG-949, 
``Permit To Carry Excursion Party,'' or in letter form. The cognizant 
OCMI will indicate on the permit the conditions under which it is 
issued, the number of persons the vessel may carry, the crew required, 
any additional lifesaving or safety equipment required, the route for 
which the permit is granted, and the dates on which the permit is 
valid. The application may be made electronically, in writing, or 
orally.
    (3) The vessel may not engage in towing during the excursion, 
unless the cognizant OCMI determines it is safe to do so.
    (d) The cognizant OCMI may require an inspection of the vessel by a 
Coast Guard Marine Inspector or an examination by a surveyor from a TPO 
prior to the vessel proceeding.


Sec.  136.250  Load lines.

    Vessels described in Table 136.250 of this section that operate on

Subpart A--General


Sec.  137.100  Purpose.

    This part describes the procedures owners or managing operators of 
towing vessels must use to demonstrate compliance with the requirements 
of this subchapter.


Sec.  137.120  Responsibility for compliance.

    (a) The owner and managing operator must ensure that the towing 
vessel is in compliance with this subchapter and other applicable laws 
and regulations at all times.
    (b) Non-conformities and deficiencies must be corrected in a timely 
manner.


Sec.  137.130  Program for vessel compliance for the Towing Safety 
Management System (TSMS) option.

    The owner or managing operator of a towing vessel choosing to use 
the TSMS option must implement an external or internal survey program 
for vessel compliance. The program for vessel compliance can be either:
    (a) An external survey program, in which the owner or managing 
operator would have a third-party organization (TPO) conduct either the 
surveys required by Sec.  137.205, the examinations required by Sec.  
137.310, or both; or
    (b) An internal survey program, in which the owner or managing 
operator would conduct either the surveys required by Sec.  137.210, 
the examinations required by Sec.  137.315, or both, using internal 
resources or contracted surveyors. The internal survey program would be 
conducted with the oversight of a TPO.
    (c) Each program of either type must include:
    (1) Owner or managing operator policy regarding the surveying and 
examination of towing vessels;
    (2) Procedures for conducting towing vessel surveys and 
examinations, as described in this part;
    (3) Procedures for reporting and correcting non-conformities and 
deficiencies;
    (4) Identification of the individual or individuals responsible for 
the management of the program, and their qualifications; and
    (5) Documentation of compliance activities.


Sec.  137.135  Reports and documentation required for the TSMS option.

compliance with the requirements of this subchapter;
    (3) Procedures for an owner or managing operator to evaluate that 
they are following their own policies and procedures and complying with 
the requirements of this subchapter;
    (4) Arrangements for a periodic evaluation by an independent third-
party organization (TPO) to determine how well an owner or managing 
operator and their towing vessels are complying with their stated 
policies and procedures, and to verify that those policies and 
procedures comply with the requirements of this subchapter; and
    (5) Procedures for correcting problems identified by management 
personnel and TPOs and facilitating continuous improvement.

Subpart C--Lifesaving Requirements for Towing Vessels


Sec.  141.305  Survival craft requirements for towing vessels.

    (a) General purpose. Survival craft provide a means for survival 
when evacuation from the towing vessel is necessary. The craft and 
related equipment should be selected so as to provide for the basic 
needs of the crew, such as shelter from life threatening elements, 
until rescue resources are expected to arrive, taking into account the 
scope and nature of the towing vessel's operations.
    (b) Functional requirements. A towing vessel's survival craft must 
meet the functional requirements of paragraphs (b)(1) through (5) of 
this section. Functional requirements describe the objectives of the 
regulation. Survival craft must:
    (1) Be readily accessible;
    (2) Have an aggregate capacity sufficient to accommodate the total 
number of individuals onboard, as specified in paragraph (c) of this 
section;
    (3) Provide a means for sheltering its complement appropriate to 
the route;
    (4) Provide minimum equipment for survival if recovery time is 
expected to be greater than 24 hours; and
    (5) Be marked so that an individual not familiar with the operation 
of the specific survival craft has sufficient guidance to utilize the 
craft for its intended use.
    (c) Compliance options. A towing vessel must meet the applicable 
functional requirements. Compliance with the functional requirements of 
paragraph (b) of this section may be met by one of these two options:
    (1) A towing vessel that meets the prescriptive requirements of 
paragraph (d) of this section will have complied with the functional 
requirements; or
    (2) If an owner or managing operator chooses to meet the functional 
requirement through means other than as specified in paragraph (c)(1) 
of this section, the means must be accepted by the cognizant OCMI or, 
if the vessel has a TSMS, then by a TPO and, in the latter case, 
documented in the TSMS applicable to the vessel. The design, testing, 
and examination scheme for meeting these functional requirements must 
be included as part of the TSMS applicable to the vessel.
    (d) Prescriptive requirements. (1) Except as provided in paragraphs 
(d)(2) through (4) of this section, each towing vessel must carry the 
survival craft specified in Table 141.305 of this section, as 
appropriate for the towing vessel, in an aggregate capacity to 
accommodate the total number of individuals onboard.

related controls on vessels that move tank barges carrying oil or 
hazardous material in bulk.

    (a) There must be an alternate means to control the propulsion and 
steering system which must:
    (1) Be independent of the primary control required by Sec.  
143.225;
    (2) Be located at or near the propulsion and steering equipment; 
and
    (3) Be readily accessible and suitable for prolonged operation.
    (b) There must be a means to communicate between each operating 
station and the alternate propulsion and steering controls.
    (c) There must be a means to stop each propulsion engine and 
steering motor from each operating station.
    (d) The means to monitor the amount of thrust, rudder angle, and if 
applicable, direction (ahead or astern) of thrust must be independent 
of the controls required by Sec.  143.225.
    (e) The propulsion control system required by Sec.  143.225 must be 
designed so that, in the event of a single failure of any component of 
the system, propeller speed and direction of thrust are maintained or 
reduced to zero.
    (f) On a towing vessel with an integrated steering and propulsion 
system, such as a Z-drive, the control system required by Sec.  143.225 
must be designed so that, in the event of a single failure of any 
component of the system, propeller speed and direction of thrust are 
maintained or the propeller speed is reduced to zero.
    (g) An audible and visual alarm must actuate at each operating 
station when:
    (1) The propulsion control system fails;
    (2) A non-follow up steering control system fails, if installed; 
and
    (3) The ordered rudder angle does not match the actual rudder 
position on a follow-up steering control system, if installed. This 
alarm must have an appropriate delay and error tolerance to eliminate 
nuisance alarms.
    (h) Alarms must be separate and independent of the control system 
required by Sec.  143.225.
    (i) A means of communication must be provided between each 
operating station and any crewmember(s) required to respond to alarms.
    (j) The two sources of electricity required by Sec.  143.555(a)(3) 
and (b)(8) must be capable of powering electrical loads needed to 
maintain propulsion, steering, and related controls for not less than 3 
hours.
    (k) The second source of supply required by Sec.  143.555(a)(3) 
must automatically start to help restore or maintain power to 
propulsion, steering, and related controls when the main power source 
fails.
    (l) Propulsion, steering, or related controls that are directly 
reliant on stored energy, such as compressed air, battery power, or 
hydraulic pressure, must have two independent stored energy systems, 
such as compressed air cylinders, battery banks, or hydraulic 
cylinders, that are capable of maintaining the vessel's propulsion, 
steering, and related controls.
    (m) After a power failure, electrical motors used to maintain 
propulsion and steering must automatically restart when power is 
restored, unless remote

[[Page 40141]]

control starting is provided at the operating station.


Sec.  143.590  Propulsor redundancy on vessels that move tank barges 
carrying oil or hazardous material in bulk.

    (a) A towing vessel must be provided with at least two independent 
propulsors unless the requirements of Sec.  143.595 are met.
    (b) There must be independent controls for each propulsor at each 
operating station.
    (c) In the event of a failure of a single propulsor, the remaining 
propulsor(s) must have sufficient power to maneuver the vessel to a 
safe location.


Sec.  143.595  Vessels with one propulsor that move tank barges 
carrying oil or hazardous material in bulk.

    (a) A towing vessel must have independent, duplicate vital 
auxiliaries. For the purpose of this section, vital auxiliaries are the 
equipment necessary to operate the propulsion engine, and include fuel 
pumps, lubricating oil pumps, and cooling water pumps. In the event of 
a failure or malfunction of any single vital auxiliary, the propulsion 
engine must continue to provide propulsion adequate to maintain control 
of the tow.
    (b) In the event of a failure, the corresponding independent 
duplicate vital auxiliary, described in paragraph (a) of this section, 
must be fully capable of assuming the operation of the failed unit.


Sec.  143.600  Alternative standards for vessels that move tank barges 
carrying oil or hazardous material in bulk.

    In lieu of meeting Sec. Sec.  143.585 through 143.595, a towing 
vessel may comply with Sections 7-5 (class ABCU) and 3-5 (class R2) of 
Part 4 of the ABS Rules for Building and Classing Steel Vessels Under 
90 Meters (295 Feet) in Length (incorporated by reference, see Sec.  
136.112 of this subchapter), except that a vessel that operates 
exclusively on rivers or intracoastal waterways does not need to comply 
with 4-7-4/3.9 and the automatic day tank fill pump requirement of 4-7-
4/25.3.


Sec.  143.605  Demonstration of compliance on vessels that move tank 
barges carrying oil or hazardous material in bulk.

    (a) The owner or managing operator of each towing vessel must 
devise test procedures that demonstrate compliance with the design and 
engineering requirements prescribed in this subpart.
    (b) The tests required in paragraph (a) of this section must be 
satisfactorily conducted and witnessed by the cognizant OCMI or a TPO. 
A record of the tests must be retained by the owner or managing 
operator and be available upon request of the cognizant OCMI or TPO.

approved lightweight characteristics.

    (a) A weight and moment history of changes to the vessel since 
approval of its lightweight characteristics (displacement, Longitudinal 
Center of Gravity (LCG) and Vertical Center of Gravity (VCG)) must be 
maintained. All weight modifications to the vessel (additions, 
removals, and relocations) including a calculation of the aggregate 
weight change (absolute total of all additions, removals, and 
relocations) must be recorded in the history, along with a description 
of the change(s), when and where accomplished, moment arms, etc. After 
each modification, the lightweight characteristics must be 
recalculated.
    (b) When the aggregate weight change is more than 2 percent of the 
vessel's approved lightweight displacement, or the recalculated change 
in the vessel's lightweight LCG is more than 1 percent of the LBP, a 
deadweight survey must be performed to determine the vessel's current 
lightweight displacement and LCG. Use the following table to determine 
when the deadweight survey results or the vessel's aggregate weight 
change requires the vessel to undergo a specified stability test:
