Bulk Solid Hazardous Materials: Harmonization With the 
International Maritime Solid Bulk Cargoes (IMSBC) Code

AGENCY: Coast Guard, DHS.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: The Coast Guard proposes to harmonize its regulations with 
International Maritime Organization (IMO) amendments to Chapter VI and 
Chapter VII to the International Convention for the Safety of Life at 
Sea, 1974, as amended, (SOLAS) that make the International Maritime 
Solid Bulk Cargoes (IMSBC) Code mandatory. The amendments require that 
all vessels subject to SOLAS and carrying bulk solid cargoes other than 
grain must comply with the IMSBC Code. The Coast Guard proposes to 
amend its regulations governing the carriage of solid hazardous 
materials in bulk to allow use of the IMSBC Code as an equivalent form 
of compliance for all domestic and foreign vessels operating in U.S. 
navigable waters. Proposed changes to the Coast Guard regulations will 
also expand the list of solid hazardous materials authorized for bulk 
transportation by vessel and include special handling procedures based 
on the IMSBC Code and existing special permits. These proposed changes 
would reduce the need for the current special permits for the carriage 
of certain solid hazardous materials in bulk.

III. Background

A. Summary of Existing Regulations

    The Coast Guard regulations governing the carriage of solid 
hazardous materials in bulk are found in 46 CFR parts 97 and 148. Part 
148 prescribes regulations for the transport of solid hazardous 
materials in bulk by vessel on U.S. navigable waters. Subpart 148.01 
includes information on applicability, special permits, and 
certification. This subpart also includes a list of permitted solid 
cargoes that may be transported without special permit from the Coast 
Guard; the list was last revised in 1984 (49 FR 16794). The list does 
not cover 30 additional solid cargoes that are now shipped in bulk by 
vessel and that require special handling procedures to ensure safety in 
transportation. The Coast Guard issues special permits specifying 
conditions under which it allows transport of these bulk solid cargoes 
by vessel.
    Subpart 148.02 includes vessel requirements for shipping papers, 
dangerous cargo manifests (DCMs), and reporting of incidents. Subparts 
148.03 and 148.04 include minimum transportation requirements for all 
bulk solid cargoes subject to Part 148, and special additional 
requirements for certain material. The special additional requirements 
are applied to solid cargoes permitted to be carried in bulk by vessel 
in accordance with Subpart 148.01.

B. Regulatory History

    This rulemaking is based on a previous rulemaking (CGD 87-069), 
which the Coast Guard closed in 1995. On April 28, 1989, the Coast 
Guard published an advance notice of proposed rulemaking (ANPRM) titled 
``Marine Transport of Bulk Solid Hazardous Materials'' in the Federal 
Register (54 FR 18308). During the 60-day comment period, the Coast 
Guard received 16 comment letters on the ANPRM, which we considered in 
developing a notice of proposed rulemaking (NPRM). The comments did not 
request a public meeting, and we did not hold one.
    On April 12, 1994, the Coast Guard published an NPRM titled 
``Carriage of Bulk Solid Materials Requiring Special Handling'' in the 
Federal Register (59 FR 17418) with a 90-day comment period. On August 
5, 1994, we extended the comment period for 30 days (59 FR 40004). The 
1994 NPRM addressed comments received on the ANPRM. The NPRM also 
included a provision regarding the carriage of coal (proposed in the 
1994 NPRM as Sec.  148.240), which was based on a report by the 
Chemical Transportation Advisory Committee (CTAC) Subcommittee on Coal 
Transportation. That CTAC report is discussed in the 1994 NPRM at 59 FR 
17420. In response to the 1994 NPRM, the Coast Guard received 65 
letters and communications containing more than 200 comments. No public 
meeting was requested, and we did not hold one.
    On April 13, 1995, the Coast Guard published a notice of 
termination in the Federal Register (60 FR 18793). At that time, we 
closed the rulemaking to focus resources on other matters. We resolved 
those matters and we are now proceeding with the rulemaking. A copy of 
the 1994 NPRM and the 1995 Termination Notice have been placed in the 
public docket for reference.

[[Page 34576]]

    In 2008 and 2009, the CTAC Subcommittee on Solid Bulk Cargoes held 
several meetings regarding the IMSBC Code and specific requirements for 
the carriage of all bulk solid cargoes by vessel. Industry provided 
extensive recommendations during these public meetings, which the Coast 
Guard considered and incorporated when developing this proposed rule. 
The meetings occurred on April 23, 2008 (73 FR 17369), September 9 and 
10, 2008 (73 FR 47202), April 21 and 22, 2009, and August 12, 2009 (74 
FR 39090). The rulemaking docket (USCG-2009-0091) contains minutes of 
these public meetings as well as the subcommittee's final report. The 
Coast Guard used CTAC's report in preparing this NPRM.
    At the time the Coast Guard published the 1994 NPRM, the 
international standard for the marine transport of solid materials in 
bulk was the Code of Safe Practice for Solid Bulk Cargoes (BC Code). 
Since the 1994 NPRM, the IMO has updated the BC Code periodically and 
renamed it the IMSBC Code. Therefore, this proposed rule is similar, 
but not identical, to that proposed in the 1994 NPRM. The Coast Guard 
encourages members of the public to comment on this NPRM, even if they 
may have submitted a similar comment in the 1994 rulemaking.
    The period for comment on this NPRM is 30 days. We believe that a 
30-day comment period is adequate in light of the long history of this 
rulemaking and the multiple opportunities for comment. As described in 
detail above, the public has commented on an ANPRM as well as an NPRM 
very similar to the rule proposed in this document, and at four public 
meetings in the last 2 years. In addition, the Coast Guard participated 
in the development of the IMSBC Code, and held public meetings prior to 
each meeting with the IMO to give shipping and cargo interests the 
opportunity to comment on IMO activities (see, e.g., 74 FR 40632, 73 FR 
51876, and 72 FR 44213). For these reasons, we believe that a comment 
period of 30 days is appropriate.

C. Changes to International Regulations That Led to This Rulemaking

    The carriage of hazardous materials in international maritime 
commerce is now governed by Chapter VII of the International Convention 
for the Safety of Life at Sea, 1974, as amended (SOLAS). In 1990 and 
1991, the IMO amended Chapter VI of SOLAS, which formerly applied only 
to grain cargoes, to include all bulk solid cargoes. The amended 
Chapter VI of SOLAS requires that the master receive written cargo 
information, that the vessel carry oxygen analysis and gas detection 
equipment on board when the cargoes to be carried are likely to emit 
toxic or flammable gases, and that the master possess information 
regarding the ship's stability and the distribution of cargo after 
loading.
    On January 1, 1994, these amendments became binding for all nations 
signatory to SOLAS, including the United States. In December, 2008, IMO 
further amended SOLAS Chapter VI and Chapter VII, to require compliance 
with the relevant provisions of the IMSBC Code for the carriage of bulk 
solid cargoes other than grain. This amendment will become binding for 
all nations signatory to the SOLAS Convention on January 1, 2011.
    The IMSBC Code, formerly known as the BC Code, is the international 
standard for the marine transport of solid materials in bulk. The IMO 
first issued it in 1965 and has amended it several times since, most 
recently in 2008. The IMSBC Code provides standards for shippers, 
vessel operators, and masters to ensure the safe handling and carriage 
of bulk solid cargoes. Implementation of the IMSBC Code will not become 
mandatory until January 1, 2011, but several countries have already 
adopted the Code, in whole or in part, as national regulation. 
Countries that are party to SOLAS will require compliance with the 
IMSBC Code for all bulk solid shipments occurring in their 
jurisdiction. Several bulk solid cargoes covered by the IMSBC Code are 
also regulated by the Coast Guard under 46 CFR part 148, under either 
the list of permitted cargoes or the terms of a special permit.
    The Secretary of Homeland Security delegated to the Coast Guard the 
authority necessary to conduct this rulemaking, including the authority 
to carry out the functions and exercise the authorities in 46 U.S.C. 
3306 and 5111, and to carry out the functions of 46 U.S.C. 3306(a)(5) 
and 49 U.S.C. 5101 et seq. relating to the regulation of bulk 
transportation of hazardous materials loaded or carried on board a 
vessel without benefit of containers or labels. Under these and other 
authorities, the Coast Guard proposes in this NPRM regulations that 
would allow the use of the IMSBC Code as an equivalent form of 
compliance with 46 CFR part 148 for international shipments originating 
or concluding in the United States, subject to conditions and 
limitations.

IV. Discussion of Comments on the 1994 Notice of Proposed Rulemaking

    In response to the April 1994 NPRM, the Coast Guard received 65 
letters and communications containing more than 200 comments. Those 
commenting included shippers, carriers, terminal operators, marine 
surveyors, trade associations, private individuals, and the Canadian 
Coast Guard. No public meeting was requested, and we did not hold one.
    In this section, we discuss the comments received on the 1994 NPRM, 
including, where appropriate, instances in which comments led to 
changes between the 1994 NPRM and this NPRM. In many cases, we no 
longer have the original comment letters submitted in 1994; instead, we 
based our discussion of those comments on summaries created in 1994, 
which we have made available in the docket. Following the discussion of 
the public comments, we summarize additional changes made to this 
proposed rule as the result of actions by the Coast Guard, the IMO, and 
the Pipeline and Hazardous Materials Safety Administration (PHMSA) 
since publication of the 1994 NPRM.

A. General Comments

    Two comments objected to the rulemaking in general, stating that 
the regulations are burdensome and unnecessary.
    We have regulated shipment of bulk solid hazardous materials for 
more than 30 years. All of the materials previously regulated and those 
to be regulated under this rulemaking have been determined through 
experience and/or scientific investigation to have characteristics that 
could endanger human life or harm the marine environment. Before 
participating in any action by IMO to develop the IMSBC Code, the Coast 
Guard sought advice from the affected segments of American industry. 
The coal industry is a particularly good example. A special working 
group from American coal and marine transportation interests 
participated in the development of the international requirements. The 
adoption of amendments to Chapter VI and Chapter VII of SOLAS require 
that all vessels subject to SOLAS and carrying bulk solid cargoes other 
than grain must comply with the IMSBC Code. It is necessary for the 
United States to update its regulations to harmonize with SOLAS 
requirements. Allowing for the use of the IMSBC Code as an equivalent 
form of compliance with 46 CFR part 148, and reducing the number of 
special permits requested and issued, will reduce some burden on both 
the Coast Guard and the shipper. The United States has been, and 
expects to continue being, a leader in international maritime safety.

[[Page 34577]]

    One comment noted that the Coast Guard was regulating in an area 
where each circumstance is different and calls for different measures. 
This comment recommended that the Coast Guard require companies 
conducting potentially risky operations to conduct a systems analysis 
similar to the process hazards analysis now required by both the 
Occupational Safety and Health Administration (OSHA) and the 
Environmental Protection Agency (EPA).
    We determined that the comment's recommendation transcends the 
scope of the present rulemaking. None of the materials regulated under 
the former rules or proposed for regulating by this NPRM have a history 
of catastrophic events that would put an entire community at risk. Only 
a few are environmentally hazardous substances of significance. The 
issue of systems analysis as proposed by the comment would be better 
addressed under a comprehensive review of the Coast Guard's port safety 
regulations.
    Ten comments proposed that the rules in Part 148 should not apply 
to unmanned barges in domestic rivers or coastwise service. We agree in 
part. We revised proposed Sec.  148.1 to exclude unmanned barges 
transporting potentially dangerous materials (PDM), such as coal and 
wood chips, from this part except when such a barge is on an 
international voyage. PDM materials have characteristics of self-
heating, flammable/toxic gas emission, or oxygen depletion. These 
materials pose little danger when transported in open hopper barges. 
This part would continue to apply to all unmanned barges transporting 
bulk materials meeting the hazardous class definitions in 49 CFR 
Chapter I, Subchapter C; for example, ammonium nitrate fertilizer and 
ferrosilicon. The term PDM is functionally equivalent to term 
``material hazardous only in bulk'' (MHB), which is used in the IMSBC 
Code.

B. Comments Relating to Specific Provisions

    1. Section 97.12-1. Four comments found the applicability statement 
confusing and the applicability of Subpart 97.12 to foreign flag 
vessels and barges unclear.
    This section has been deleted from the proposed rule. The vessel 
applicability rules from Part 90 apply.
    2. Section 97.12-3. One comment remarked that not all vessels 
subject to the rules would have masters.
    We determined that no change is necessary. Unmanned barges are 
exempt from Subpart 97.12 and all other vessels have masters.
    3. Section 148.3.
    a. Adjacent space. Two comments questioned the definition of 
``adjacent space.'' One asked whether an adjacent space included 
penetrations, such as cable runs and pipes, in a bulkhead separating a 
space from a cargo hold, if those penetrations were gas-tight. The 
other stated that spaces having a high rate of air exchange that 
negates the potential for the accumulation of toxic or flammable gases 
should not be considered adjacent spaces.
    To the first comment, the Coast Guard explains that if a cable or 
pipe passes through the common bulkhead or deck in a stuffing tube or 
packing gland, the space is considered an adjacent space. If a pipe is 
welded where it passes through the common bulkhead or deck, it is not a 
penetration for the purposes of this definition.
    To the second comment, we point out that the definition of adjacent 
space relates only to the location of a space in relation to a cargo 
hold containing bulk solid materials requiring special handling. The 
atmospheric conditions in the space are not addressed in the 
definition. Ventilation of adjacent spaces is addressed for specified 
cargoes.
    b. Hot-molded briquettes. One comment pointed out that the 
definition of ``hot-molded briquettes'' is not consistent with the BC 
Code (now replaced by the IMSBC Code).
    The IMSBC Code defines hot molded direct reduced iron (DRI) as 
briquettes molded at a temperature of 650 [deg]C or higher that have a 
density of 5.0 g/cm[sup3] or greater. The 1994 NPRM had stated that DRI 
briquettes were either molded at a temperature of 650 [deg]C or higher 
or had a density of 5.0 g/cm[sup3] or greater. In this proposed rule, 
we have revised the proposed definition to match the IMSBC Code.
    c. Surface ventilation. One comment asked if the definition of 
``surface ventilation'' included both active (fan-induced) and passive 
(hatch cover vents) ventilation.
    The answer is yes. In this proposed rule, we have expanded the 
definition accordingly.
    4. Section 148.5. One comment supported acceptance of alternative 
procedures set out in Sec.  148.5.
    5. Section 148.8. One comment proposed that Section 4 of the BC 
Code (now IMSBC Code) be incorporated by reference. The section deals 
with assessing the acceptability of consignments for safe shipment.
    Section 4 of the IMSBC Code contains provisions for information to 
be given to the master prior to loading, and retained on board during 
carriage. This section of the IMSBC Code is incorporated by reference 
for international shipments under Sec.  148.55 of the proposed rule. 
For domestic shipments, equivalent measures are contained in Sec. Sec.  
148.60 and 148.70.
    6. Section 148.10.
    a. One comment found the proposed rules ``grossly inadequate'' in 
how they protect merchant mariners from exposure to hazardous 
substances. Commenting on footnotes 7, 8, 10, 12, and 15 of proposed 
Table 148.10, this comment recommended that the Coast Guard either 
adopt OSHA standards for personal protective equipment or develop its 
own equivalent standards.
    We recognize that this regulation does not contain all the 
requirements necessary for a comprehensive health and safety program. 
In our Navigation and Vessel Inspection Circular (NVIC) 3-92 of 
February 24, 1992, however, we provide the marine industry with 
guidance for such a program.
    In this proposed rule, we have retained requirements for the most 
important health and safety issues related to the transportation of 
materials regulated in Part 148. These include general requirements to 
treat all cargo holds as confined spaces, and specific requirements 
that are deemed necessary due to unique hazards of certain bulk solid 
materials. In this proposed rule, a new section, Sec.  148.86, 
containing requirements for confined space entry has replaced the 
``special requirements'' proposed in Sec. Sec.  148.425 and 148.430 in 
the 1994 NPRM Sec.  1. Also, we have added a definition of ``confined 
space'' to Sec.  148.3.
    b. One comment suggested that an entry for ``ammonium nitrate, UN 
1942'' be added to Table 148.10.
    We agree and we have adjusted this proposed rule accordingly. The 
footnotes and special requirements in the new entry would be the same 
as for ammonium nitrate fertilizer, UN 2067.
    c. Four comments opposed the classification of coal as PDM and/or 
requested that the transport of coal be removed from the rulemaking.
    We did not adopt this request. The IMSBC Code provisions for 
transport of coal are the result of a U.S. initiative developed with 
the knowledge, assistance, and concurrence of the U.S. coal industry. 
Where the 1994 rulemaking was not in harmony with the IMSBC Code, we 
have revised this proposed rule accordingly. The burden on the coal 
industry would be lessened by exempting domestic barge shipments of 
PDM, as is provided by this rulemaking.

[[Page 34578]]

    d. Concerning the list of sections containing special requirements 
for coal, one comment observed that Sec. Sec.  148.15, 148.80, 148.90, 
148.100, 148.110, 148.115, and 148.120 also apply to coal.
    Although this is generally true, Sec.  148.15 does not apply to 
coal; therefore, no change to Table 148.10 is necessary to make 
reference to this section. The other sections cited by the comment 
contain general requirements that apply to all commodities listed in 
the table, and are not specific to coal.
    e. One comment questioned the applicability to coal of footnote 24 
of proposed Table 148.10, cargoes subject to liquefaction, stating that 
liquefaction cannot occur with coal.
    Based on the IMSBC Code and other information available to the 
Coast Guard, we believe liquefaction can indeed occur with coal if the 
coal is in a finely divided form. In order to clarify this, proposed 
Sec.  148.450, ``Cargoes subject to liquefaction,'' states that it does 
not apply to cargoes of coal that have an average particle size of 10 
mm (.394 in.) or greater. The average particle size is based on the 
definition of ``fine-grained materials'' in Appendix 2 of the IMSBC 
Code.
    f. One comment requested that footnote 11, which indicates that 
petroleum coke is susceptible to spontaneous heating and ignition, be 
removed from the entry for petroleum coke in Table 148.10. The comment 
states that this footnote is not appropriate.
    We found that the IMSBC Code identifies spontaneous heating and 
ignition as a characteristic of petroleum coke, and we have left this 
as a hazardous or potentially dangerous description for petroleum coke.
    g. One comment opposed classification of sawdust and wood chips as 
PDM.
    We disagree. The Coast Guard's Bulk Solid Cargoes regulations have 
listed sawdust as a regulated material since before 1976. Under this 
proposed rule, we would regulate sawdust as PDM when carried by cargo 
vessel; it is currently regulated as an Other Regulated Material--Class 
C (ORM-C). However, the proposed rule does not apply to domestic barge 
shipments. The principal hazard associated with these materials, 
sawdust and wood chips, is oxygen depletion in confined spaces. Since 
these materials are usually transported domestically in open hopper 
barges, oxygen depletion is not a significant hazard.
    h. One comment recommended that an entry for Sulfur, NA 1350, 
Hazard Class 9, be added to 49 CFR Table 172.101 to be used for 
domestic transportation of sulfur.
    We agree that this addition would be consistent with the entries 
for sulfur in 49 CFR Table 172.101. The entry for sulfur that is 
assigned to NA 1350 may be used only for domestic transportation. The 
proposed entry for Sulfur UN 1350, Hazard Class 4.1, has been retained 
for international transportation. The footnotes and special 
requirements of both entries are the same.
    7. Section 148.12.
    a. This was one of the most controversial provisions of the 1994 
NPRM. Seventeen comments objected to this provision on the grounds that 
it would create a monopoly by naming the National Cargo Bureau, Inc. 
(NCB), as the exclusive agency for assisting the Coast Guard in 
administering Part 148. The comments requested that we authorize other 
competent entities to assist in the administration of these 
regulations.
    Since 1952, the Coast Guard's hazardous materials regulations 
(HMRs) have contained a provision recognizing NCB. As proposed in 1994, 
Sec.  148.12 (to replace existing Sec.  148.01-13) granted no monopoly 
to the NCB, did not require that its services be used, and did not 
prohibit carriers from employing other surveyors. In this proposed 
rule, we have retained this section with only minor revisions.
    b. One comment noted that Sec.  148.12 implies mandatory Coast 
Guard inspection of each barge, creating a delay that would have an 
adverse economic impact.
    This is not the case. Proposed Sec.  148.12 in no way mandates 
inspection of every barge. We have the authority to inspect barges or 
other vessels to ensure compliance with the regulations, but in 
practice we do not carry out inspections of 100 percent of the affected 
vessels. The employment of NCB or any recognized marine surveying 
organization is voluntary on the part of a vessel operator.
    8. Section 148.55. One comment noted that proposed paragraph (b) of 
this section, by authorizing compliance with international requirements 
in lieu of compliance with Part 148, may preclude some other 
regulations in Part 148.
    As the rule was proposed in the 1994 NPRM, this would have been 
true. However, it was not the Coast Guard's intent that this provision 
should obviate the requirements concerning environmentally hazardous 
substances or zinc ashes. In this proposed rule, we have revised 
paragraph (b) of this section to require that these commodities must 
comply with Part 148 in addition to the IMSBC Code. We are not aware of 
any other provisions in this rulemaking that are significantly more 
stringent than the IMSBC Code.
    9. Section 148.60.
    a. One comment recommended that shipping papers include the 
shipper's and transporter's Hazardous Materials Registration Number.
    Under PHMSA regulations at 49 CFR part 107, subpart G, registration 
is required only for shippers and transporters of certain packaged 
hazardous materials. Registration is not required for shippers or 
transporters of bulk materials, including solid materials, liquid 
chemicals, and compressed gases. Therefore, not all shippers and 
transporters of bulk solid materials will have Hazardous Materials 
Registration Numbers.
    b. One comment stated that the proposed regulation provided 
inadequate protection regarding shipment by barge. Because barges do 
not have masters, there is no one to hold responsible for accepting the 
commodity.
    We point to Sec.  148.2, proposed in this rulemaking, which places 
the duty to comply with these regulations on ``each master of a vessel, 
person in charge of a barge, owner, operator, charterer, or agent.'' We 
propose to revise the definition of ``master'' in Sec.  148.3 to 
indicate that the person in charge of a barge may perform the functions 
of a master for the purposes of this proposed rule. We also propose to 
add the definition of ``person in charge of a barge'' to Sec.  148.3.
    c. One comment requested that the Coast Guard define the format or 
document to be used for notification of the master.
    We do not intend to impose a format for communications between 
shipper and carrier. A single format cannot take into account all forms 
of communication between all types of shippers and carriers. 
Documentation should be in a form acceptable to both parties.
    d. One comment suggested that it may be good practice to have a 
material safety data sheet (MSDS) address some portions of proposed 
Sec.  148.60.
    We agree with the comment, but point out that proposed Sec.  148.61 
already allows hazardous materials information to be provided in the 
form of an MSDS.
    e. One comment observed that, as proposed in the 1994 NPRM, Sec.  
148.60(d) negated the requirement for shipping papers for shipments of 
PDM, including coal.
    In this proposed rule, we have resolved this issue by removing

[[Page 34579]]

paragraph (d) of Sec.  148.60. Because of the proposed applicability 
provisions at Sec.  148.1, shipping papers would be required for all 
shipments of hazardous materials and PDM by cargo vessel, and by 
unmanned barge if the barge is on an international voyage. Shipping 
papers are not required for PDM when transported by barge in domestic 
transportation.
    f. One comment stated that the shipping paper requirements for PDM 
in the 1994 proposal were not clear; this comment proposed that the 
requirement for shipper advice be dropped.
    Shippers' advice to the master is essential for many materials. The 
shipper has the most knowledge of the characteristics and hazards of 
the material and therefore can provide the best advice for shipping. 
This information most commonly is conveyed through shipping papers and 
DCMs. Under SOLAS, shipping papers and a DCM are required for all 
hazardous cargoes. Therefore, in this proposed rule, we removed the 
exception for PDM in international commerce. Because of the proposed 
revision to the applicability provisions at Sec.  148.1, neither 
shipping papers nor a DCM are needed for shipments of PDM by unmanned 
barge in domestic transportation.
    10. Section 148.62. Two comments did not believe safety would be 
meaningfully enhanced by a requirement to transfer and maintain aboard 
an unmanned barge written information on the hazards of these cargoes.
    The proposed regulations require that the shipping paper and 
emergency response information be kept on the tug or towing vessel, or, 
in the case of a moored barge, in a readily retrievable location. The 
purpose of this requirement includes the safety of first responders. If 
an incident should occur on board the barge, it is essential that 
personnel responding can obtain emergency response information. If the 
shipper or the master of a vessel or person in charge is not available, 
this may be the only source of information on the cargo.
    11. Section 148.70.
    a. One comment requested that barges be exempt from the requirement 
for a DCM.
    Under the revised applicability provisions of this proposed rule, 
barges are exempt from DCM requirements unless they are on an 
international voyage. On international voyages, barges carrying Class 4 
through 9 hazardous materials in bulk must comply with SOLAS and 
therefore must have a DCM.
    b. Another comment questioned whether a DCM is required for 
materials classed as PDM.
    The answer is no. A DCM is required only when a cargo vessel (or a 
barge on an international voyage) transports bulk materials of Hazard 
Classes 4 through 9.
    c. One comment recommended that a DCM be required for unmanned 
barges.
    We partially agree. Under SOLAS, an unmanned barge carrying bulk 
hazardous materials other than PDM on an international voyage must have 
a DCM on board. For barges in domestic transportation, however, the 
information required to be on the DCM is either not applicable or is 
redundant to information presented on the shipping paper. The shipping 
paper required on board the towing vessel or on the barge under 
proposed Sec.  148.60 provides sufficient information.
    12. Section 148.80.
    a. One comment asked whether the definition of ``responsible 
person'' included members of a ship's crew designated by the master or 
his deputy and noted that, if so, no changes in current practices are 
implied.
    This definition as referenced by the comment is the intended 
definition of ``responsible person.'' The responsible person must be a 
person empowered by the master of a vessel or the owner or operator of 
a barge to make all decisions relating to his or her specific task and 
must have the necessary knowledge and experience for that purpose. We 
have added this definition of ``responsible person'' to proposed Sec.  
148.3.
    b. Another comment asked whether these regulations would require 
either the vessel or the shipper to provide a ``responsible person'' to 
supervise the loading.
    The answer is yes. The proposed rule requires that a responsible 
person be assigned by either the master of the vessel or the owner or 
operator of a barge.
    13. Section 148.90.
    a. Eighteen comments questioned the need for holds to be thoroughly 
cleaned of the previous cargo when the same cargo is to be loaded 
again.
    We believe that the 1994 NPRM was ambiguously worded with regard to 
the cleaning of cargo holds. The current proposed rule clarifies that 
thorough cleaning is required only when the previous cargo is 
incompatible with the cargo being loaded. Compatibility is determined 
by reference to the stowage and segregation requirements in Subpart D 
of Part 148.
    b. Four comments stated that the requirement that each cargo hold 
be as dry as practicable was in itself not practical.
    The proposed rule clarifies that this requirement applies only to 
bulk solids that are dangerous when wet or that are subject to 
liquefaction.
    c. Two comments expressed the need for shippers to advise masters 
of Great Lakes vessels regarding stowage factors and trimming, because 
of the unique design and operating mode of these vessels. According to 
the comments, the best course of action is to test every coal cargo for 
methane regardless of information provided by the shipper.
    We agree. The IMSBC Code requires that the atmosphere above the 
cargo in each hold containing coal be regularly monitored for the 
concentration of methane, oxygen, and carbon monoxide with procedures 
outlined in Appendix 1.
    d. Another comment recommended that the requirement to provide 
information on the chemical properties and related hazards of coal and 
petroleum coke should be omitted.
    We disagree. In the interest of safety, the master of the vessel 
must be fully informed of the nature of the material to be loaded. The 
regulations, it should be noted, do not stipulate that the chemical 
properties and related hazards information must be provided for each 
shipment. For repetitious shipments by a single shipper of a material 
whose characteristics remain unchanged, this information need only be 
provided once and retained on file.
    14. Section 148.100. One comment recommended that recording the 
details of cargo monitoring and gas testing in a separate dedicated 
book should be allowed to continue. The ship's log need only make 
reference to such testing or monitoring.
    We agree with the comment and revised proposed Sec.  148.100 
requiring that the date and time be recorded in the ship's log. The 
proposed rule requires only that the detailed information be recorded, 
and does not specifically require that it be recorded in the ship's 
log.
    15. Section 148.110. One comment stated that a cautionary statement 
referring to 33 CFR part 151 might be appropriate for inclusion in 
Sec.  148.110.
    We agree. Under 33 CFR part 151, operational and maintenance wastes 
such as cargo residues and deck sweepings are considered ``garbage.'' 
When on U.S. territorial seas or inland waters, cargo residues and deck 
sweepings must be retained on the vessel and disposed of as specified 
in that part; therefore, we included this information in the proposed 
Sec.  148.110.
    16. Section 148.150. One comment requested that a provision be 
added under Sec.  148.150 to read ``sulfur must be

[[Page 34580]]

segregated as required in Sec.  148.120 for Class 4.1 materials.''
    We agree with the comment and made this revision.
    17. Section 148.155. One comment interpreted this section as 
requiring separation by one complete cargo compartment between two PDM 
commodities. They doubted that a vessel would be capable of sailing 
with an empty intermediate cargo compartment without stressing the 
vessel.
    This comment likely refers to proposed Sec.  148.155(d)(2). The 
separation provision applies only when the temperature of petroleum 
coke is 55 [deg]C (131 [deg]F) or higher when loaded. The purpose of 
this requirement is to prevent contact between a bulkhead of a cargo 
hold containing hot hazardous material and a cargo in an adjacent cargo 
hold that is sensitive to heat. If it is necessary to transport 
petroleum coke in a hold adjacent to other hazardous materials, the 
solution is to not load hot petroleum coke until its temperature 
decreases to below 55[deg]C. Alternatively, if possible, nonhazardous 
cargo could be stowed in the intervening hold.
    18. Section 148.205.
    a. One comment stated that the temperature limitations for ammonium 
nitrate fertilizer should be ensured by monitoring and controlling 
temperature at the output from the manufacturing process rather than by 
temperature probes once the material is loaded.
    We agree that the temperature of ammonium nitrate fertilizer or any 
other bulk commodity is best controlled through the manufacturing 
process. However, only monitoring immediately before loading would 
ensure that the temperature of the cargo on the vessel is within safe 
limits.
    b. One comment asked if the detonation test prescribed by The 
Fertilizer Institute was acceptable as an equivalent test under Sec.  
148.205(b).
    In this proposed rule this test has not been added to the list of 
allowable tests because it is no longer being maintained by The 
Fertilizer Institute. Therefore, the detonation test prescribed by The 
Fertilizer Institute is not acceptable as an equivalent.
    c. One comment stated that Sec.  148.205(c)(1) is a reasonable 
requirement provided it does not mean that each load offered for 
shipment has to be tested. According to the comment, test data on file 
supporting the classification by the manufacturer should be sufficient.
    This proposed provision does not imply that testing is required for 
each shipment as long as the chemical composition of the material being 
shipped has not changed.
    d. One comment noted that this section is deficient because it 
refers only to the ``master'' when the vessel may be a barge.
    To clarify the applicability of this and similar provisions, we 
proposed to revise the definition of ``master'' in Sec.  148.3 to 
include the ``person in charge of a barge,'' and add a definition of 
``person in charge of a barge'' to that section.
    e. One comment questioned the prohibition on fuel oil transfer 
during loading of ammonium nitrate fertilizers. This comment saw no 
reason why internal fuel transfers should not be permitted.
    The purpose of prohibiting bunkering and fuel transfers during the 
handling of ammonium nitrate and ammonium nitrate fertilizers is to 
preclude any possibility of forming an explosive mixture through the 
contamination of the ammonium nitrate. This prohibition does not extend 
to transfers of fuel on board the vessel through the vessel's fixed 
piping system. We have reworded the section to clarify this.
    19. Section 148.225. One comment recommended that Sec. Sec.  
148.225 and 148.315 address the proper disposal of residue that has 
been ``hosed down'' or ``washed down with fresh water.'' Another 
similar comment recommended that Sec.  148.315 should address proper 
disposal of sulfur residue that has been ``hosed down'' or ``washed 
down with fresh water.''
    Although the provision for washing down with fresh water is a 
direct quotation from the IMSBC Code, we recognize that it conflicts 
with Annex V of The International Convention for the Prevention of 
Pollution from Ships (MARPOL 73/78) and 33 CFR part 151. Instead, in 
these sections, we propose to refer to 33 CFR parts 151.55 through 
151.77.
    20. Section 148.240.
    a. One comment believed there should be some discrimination between 
supply and exhaust fans in determining which must be ``safe for use in 
an explosive gas atmosphere.'' The comment recommended that all 
existing fans should be ``grandfathered.''
    We disagree. Both intake and exhaust fans must be explosion-proof 
for two reasons. First, ventilation fans on board a vessel are often 
dual purpose, serving as both intake and exhaust. Second, pockets of 
gas may accumulate within the housings of both intake and exhaust fans 
during periods of non-use, creating the possibility of explosion.
    b. Two comments expressed an objection to any broad-brush statement 
classifying all coals as hazardous material.
    We support the determination by the IMO that, while some coals are 
more hazardous than others, all have the potential to be hazardous. We 
note that the U.S. coal industry was represented on the working group 
that recommended provisions eventually included in the IMSBC Code.
    c. One comment remarked that the requirements for coal were 
different and less demanding than the current recommendations contained 
in the BC Code (now the IMSBC Code).
    Although phrased differently from the IMSBC Code, the proposed 
provisions of this chapter concerning coal (not limited to Sec.  
148.240) are neither different nor less demanding than those of the 
IMSBC Code.
    d. Another comment proposed that some recognition be shown for the 
unique construction of the Great Lakes self-unloading vessel.
    We accept the fact that Great Lakes vessels may have certain unique 
features. However, they are exceptions to the general case addressed in 
these regulations. If owners/operators of Great Lakes vessels cannot 
comply with this proposed rule, but can provide equivalent safety 
through alternative means, they may take advantage of the alternative 
procedures provisions of Sec.  148.5.
    e. One comment found Sec.  148.240(a) not specific enough to 
establish the types of electrical fittings that are required.
    We determined that 46 CFR part 111, subpart 111.105, is sufficient 
in clarity. An item of electrical equipment must be tested or approved 
in order to comply with IEC 79 series publications. The specific 
requirements are stated in 111.105-7(a) and (b) and a reference is made 
to this section in 148.240.
    f. Another comment noted that Sec.  148.240(a) did not apply to 
adjacent spaces because Sec.  148.18(b) recognized that such spaces may 
have electrical equipment that is not certified safe for use in an 
explosive gas atmosphere.
    This comment is correct. Paragraph Sec.  148.240(a) has been 
revised so that it refers only to electrical equipment in cargo holds.
    g. Fifteen comments expressed very serious objections to the 
provision that the temperature of coal at the time of loading not 
exceed 41 [deg]C (105 [deg]F), or 15 [deg]C (27 [deg]F) above the 
ambient temperature.
    We agree with the comments. The temperature requirements in the 
1994 NPRM were not consistent with the IMSBC Code and have been removed 
from this proposed rule.

[[Page 34581]]

    h. Three comments stated that the wording of the requirement for 
trimming, i.e., ``reasonably level,'' was subject to various 
interpretations. They recommended that the subjective nature of this 
section be eliminated by incorporating some quantitative factor, such 
as a maximum height of the peak of the pile expressed as a percentage 
of the vessel's beam.
    We recognize the subjective nature of this provision but find it to 
be impractical to impose an arbitrary quantitative standard for 
``level.'' We have therefore removed this language from the proposed 
rule. The shipper will be responsible for providing trimming 
information in accordance with the new proposed shipping paper 
requirements.
    i. Two comments observed that Sec.  148.240(c)(1) provided no 
definition of ``sealed'', but advised that self-unloading vessels 
cannot meet this sort of ``sealing'' requirement in all cases. The 
comments noted that a number of obvious exemptions would be necessary.
    We find that the concept of ``sealed'' requires no regulatory 
definition. The purpose of sealing the accesses and hatches is to 
prevent the escape of methane from the hold into other spaces on the 
vessel. This paragraph has been revised to clarify that, because of 
their design, the unloading gates on self-unloading vessels are not 
required to be sealed.
    j. One comment found the 1994 NPRM unclear as to the meaning of the 
word ``casing,'' and assumed that this refers to access trunks.
    We agree. ``Casing'' is the term employed by the IMSBC Code. By 
common definition, a ``casing'' is the metal enclosure around a space 
such as an ``access trunk.'' To eliminate confusion, the word 
``casing'' has been removed in this proposed rule.
    k. One comment noted that there was no reference to the tunnel 
spaces on self-unloading vessels in the section on coal, and suggested 
they be included in Sec.  148.240(c)(2).
    We have adopted this suggestion in the proposed rule.
    l. Three comments inquired as to what specifically are ``hot 
areas'' and what is considered adequate ventilation.
    We agree that the use of the term ``hot areas'' in the 1994 NPRM 
was vague, and we have deleted it from this rulemaking.
    In the context of Sec.  148.240(c)(2), adequate ventilation means 
an air exchange that prevents an accumulation of gas that may be 
harmful to personnel in working spaces. The ventilation may be natural 
or mechanical and should be commensurate with the risk of exposure of 
the space to harmful gases.
    In the context of Sec.  148.240(c)(3), adequate ventilation means 
surface ventilation as defined in Sec.  148.240(f). Ventilation has 
been defined in the definition section, Sec.  148.3.
    m. One comment stated that paragraph (d) of this section was 
redundant by virtue of paragraphs (e), (f), and (i).
    We do not agree. Paragraph (d) states a general prohibition on 
ventilation applicable to all shipments of coal. Paragraph (e) requires 
the temperature of coal, known to be, or suspected of being, 
susceptible to self-heating, to be monitored. Paragraph (f) provides an 
exception to paragraph (d) for coals that generate methane. Paragraph 
(i) prescribes that the atmosphere in a hold containing a coal 
described in paragraph (e) must be monitored for carbon monoxide. There 
is no redundancy between paragraph (d) and any other paragraph or 
combination of paragraphs.
    n. One comment asserted that the requirement to provide 
characteristics of the cargo is the responsibility of the shipper or 
his appointed agent, and objected to the reference in the 1994 NPRM to 
information about the cargo possessed by the terminal operator and/or 
vessel operator. Another comment noted that the requirement to monitor 
coal temperatures before loading should be the responsibility of the 
shipper. Three other comments stated the view that shippers at times 
may find it difficult or impossible to obtain the required information. 
These comments stated that shippers should not be liable for 
information they do not have.
    In response to all of these comments, the Coast Guard replies that 
someone in the transportation chain must accept responsibility for the 
condition of a material to be loaded aboard a vessel. Logically, the 
primary responsibility resides with the person who offers the material 
for shipment. This person is responsible for knowing the specific types 
of cargoes being shipped and their hazardous characteristics. This 
responsibility does not absolve the terminal operator, who may have 
information about cargoes obtained through experience or observation, 
from an obligation to pass such information on to the master, nor does 
it absolve the master, who has the final responsibility for the safety 
of his vessel. This proposed rule clarifies that the master is 
responsible for monitoring the temperature of the coal.
    o. Several comments requested clarification as to what triggers the 
requirement for ventilation of the cargo space. Three comments stated 
that the term ``freshly mined'' was a subjective judgment and needed to 
be clarified. One comment requested clarification of what ``history'' 
would trigger the ventilation requirements for coal.
    This section has been revised in the proposed rule to emphasize the 
coal's potential for emitting methane as the trigger for requiring 
ventilation of the cargo space.
    p. One comment requested that temperature monitoring be waived with 
respect to coal stored in rail cars before loading.
    As amended, the proposed rule does not specifically require 
monitoring the temperature of coal that is stored in rail cars before 
it is loaded.
    q. One commenter asked if there is a specific standard for 
electrical equipment and cables in a hold containing coal, to ensure 
that they are suitable for use in a potentially explosive atmosphere.
    Proposed Sec.  148.240(g) specifies that the electrical equipment, 
and by implication its associated fittings, must comply with 46 CFR 
111.105, which applies to installation of electrical equipment in 
hazardous locations.
    r. One comment noted that the meaning of the expression ``may not 
be de-energized'' was not clear, and asked whether this statement was 
prohibitive or permissive.
    According to Federal Register drafting conventions, the term ``may 
not'' or ``No person may'' always implies a prohibition. However, we 
have rephrased this paragraph for clarity.
    s. Two comments recommended that electrical equipment in adjacent 
spaces be allowed to meet then-current Coast Guard requirements as long 
as these spaces are periodically monitored for the presence of 
explosive gas.
    Under 46 CFR 111.105-35, existing electrical equipment in cargo 
holds containing coal must now be suitable for use in an explosive gas 
atmosphere. In adjacent spaces, electrical equipment may be suitable 
for use in nonhazardous atmospheres provided such equipment is de-
energized if the concentration of flammable gas in the space reaches a 
dangerous level. Because this proposed rule introduces no new 
requirements, there is no need to ``grandfather'' existing 
installations.
    t. One comment questioned the exception from gas emission 
monitoring for voyages of 72 hours or less, noting that all research 
data indicates that methane has the potential to leak from coal 
immediately and that occurrences of this sort have resulted in several 
accidents.
    This exception was included in the 1994 NPRM to account for vessels

[[Page 34582]]

operating on the Great Lakes. The Coast Guard recognized the merit of 
the comment and removed the exception from this proposed rule.
    u. One comment assumed that opening a ``booby hatch'' or vent pipe 
would not be construed as ``opening the cargo hatches or entering the 
cargo hold.''
    The comment's assumption is correct.
    v. Three comments noted that it had been the Chemical 
Transportation Advisory Committee (CTAC) Subcommittee's intent to 
exempt unmanned barges from all requirements to test the atmosphere 
above the coal.
    The Coast Guard has proposed to exempt unmanned barges that are 
carrying any PDM, including coal, from the applicability of this part 
unless the barges are on an international voyage.
    w. Two comments noted that, for coal, the procedure in this section 
for taking pre-loading temperature readings would not always be 
effective in determining the true status of the stockpile or cargo. 
Additionally, they questioned the absence of a provision for continuous 
electronic (infrared) temperature monitoring, a procedure that is 
available at some export terminals and that has been proven effective 
and reliable.
    We removed the pre-loading temperature limitations for coal. As a 
means of monitoring the temperature increase for self-heating coal in 
the cargo hold of a vessel, we believe the procedure outlined in Sec.  
148.240(e) is satisfactory. The Coast Guard does not discount 
continuous electronic (infrared) temperature monitoring but has not had 
an opportunity to assess its equivalence to the method specified. 
Anyone wishing to use continuous electronic monitoring may request 
authorization under Sec.  148.5.
    21. Section 148.245.
    a. Two comments noted that the procedures for loading DRI and metal 
sulfide concentrates in rain or snow were not addressed. They proposed 
that the rule include detailed procedures for monitoring rainfall and 
calculating the resulting moisture content, and provisions for 
communicating this information with the vessel master and terminal.
    The Code of Federal Regulations (CFR) cannot serve as a detailed 
instruction manual for safe handling and loading of cargoes. It is the 
shipper's responsibility to provide DRI to the master of the vessel in 
an acceptable condition. Section 148.245.3(c) prohibits acceptance for 
transport of DRI or cold-molded briquettes that are wet or are known to 
have been wetted. How this condition is achieved and maintained is left 
to the shipper's good judgment.
    b. One commenter felt that Sec.  148.250(d), which prohibits the 
loading of DRI hot-molded briquettes during periods of rain or snow, 
was overstated.
    We do not agree with this comment. This prohibition is a 
precautionary measure for keeping cargoes as dry as practicable. When 
DRI hot-molded briquettes are exposed to water, they react, releasing 
hydrogen that initiates self-heating of the cargo. As seen in several 
incidents over the past years, this self-heating can ultimately lead to 
auto ignition of the cargo, causing a fire or an explosion within the 
hold and endangering the life of the crew.
    c. One comment requested a definition of ``short international 
voyage.''
    After further review, we have removed this terminology from the 
proposed rule.
    d. Another comment stated that while this section offers protection 
to radar and RDF scanners on board the vessel transporting DRI, it 
fails to offer any protection to the crew, adjacent property owners, 
etc., from the same dust which would damage the radar.
    The Coast Guard's statutory mandate is to protect life and property 
at sea and to assure preservation of the marine environment. A ship's 
navigation systems are vital to such protection. Under this rulemaking 
and OSHA regulations, crewmembers and other persons engaged in cargo 
handling operations must wear protective clothing and respiratory 
devices when handling dusty cargoes. The protection of adjacent 
property and persons not employed by the terminal or the carrier is 
under the purview of EPA air pollution regulations or local statutes 
and is beyond the scope of this project. If cargo is appropriately 
loaded and shipped, the amount of dust released into the environment 
should be minimal.
    22. Section 148.265(g). One comment felt that the requirement to 
take and record the temperature of fish meal or fish scrap three times 
a day during a voyage was particularly onerous for unmanned barges.
    We agree that taking the temperature three times a day is 
impractical on an unmanned barge, especially when that barge is part of 
a multi-barge tow. The proposed rule excludes unmanned barges from the 
temperature-measurement requirement.
    23. Section 148.270. One comment found Sec.  148.270(d) misleading 
and thought that it might exceed Coast Guard authority.
    What specifically was ``misleading'' was not stated. However, this 
provision does not exceed Coast Guard authority. It merely directs 
those persons responsible for loading or unloading a vessel to take all 
reasonable precautions to prevent dispersal of a hazardous substance 
into the environment, and to report any spill to the National Response 
Center in accordance with EPA regulations. In the proposed rule, the 
final sentence has been revised to refer to the ``garbage'' disposal 
requirements of 33 CFR part 151.
    24. Section 148.285.
    a. One comment asked the Coast Guard to advise on the format or 
type of document to be used for notifications to the master of the 
vessel.
    We do not intend to impose a format for communications between 
shipper and carrier. Documentation should be in a form acceptable to 
both parties. The language of notification to the master has been 
removed from this section because that information is already contained 
in the proposed Sec.  148.60.
    b. One comment stated that if the sampling of metal sulfide 
concentrates is not conducted correctly, and, in fact, is not 
representative of the entire consignment at the time of shipment, then 
the test procedures may show the cargo safe to transport when this is 
not the case.
    The statement is correct. We expect the information a shipper 
provides to the master to be both accurate and detailed.
    25. Section 148.295. One comment noted that the 1994 NPRM Sec.  
148.295 made no mention of the self-heating or spontaneous ignition 
characteristic of petroleum coke, despite a reference to it in the 
hazardous or potentially dangerous characteristic column of Table 
148.10, footnote 10, found in Sec.  148.11.
    This comment is correct. Text has been added to 148.295(g) 
regarding spontaneous heating of this cargo and the necessity of 
temperature monitoring during transport.
    26. Section 148.310.
    a. One comment suggested removing seed cake identification numbers 
UN 1386 and UN 2217 from the rule.
    We have not accepted this suggestion. The United Nations Committee 
of Experts and the IMO recognize seed cake as a material that may self-
heat and, if containing an excessive amount of oil, may be 
spontaneously combustible. Further, when transported in packages, this 
commodity is regulated as a hazardous material of Class 4.2 in all 
modes under PHMSA regulations at 49 CFR Chapter I, Subchapter C.

[[Page 34583]]

    b. One comment recommended that the Coast Guard amend the rule to 
be consistent with long-established industry standards for seed cake. 
Two comments proposed that the exemption from Special Permit 
requirements not be limited to solvent-extracted rapeseed meal, 
pellets, and soya bean meal, but should be extended to other types of 
seed cake if they meet the prescribed oil and moisture content levels. 
A fourth comment requested that the total oil and moisture requirement 
for cottonseed meal be raised to a maximum of 6 percent.
    The criteria for seed cake, UN 1386, are based on the established 
criteria for classification of hazardous materials as contained in 
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) and the 
United Nations Recommendations on the Transport of Dangerous Goods. 
Exemptions that were granted to rapeseed meal, pellets, and soya bean 
meal were based on testing conducted on a world-wide basis that showed 
these specific products, with varying moisture content, did not qualify 
as hazardous materials. The oil and moisture requirement for cottonseed 
meal could possibly be amended if tests are conducted using approved 
methods and the results show that it is not dangerous. If the seed cake 
industry wishes to have certain materials deregulated when transported 
in bulk, they may petition the Coast Guard following the process in 33 
CFR 1.05-20.
    27. Section 148.325.
    a. Two comments requested that sawdust and wood chips not be 
included in these regulations.
    Sawdust and wood chips, which are classed as PDM, would not be 
regulated when transported domestically in unmanned barges. However, 
the regulations would continue to apply to sawdust and wood chips 
transported by cargo vessel in international commerce.
    b. One comment requested that the Coast Guard clarify that having 
hatch covers completely open when loading wood chips would negate the 
need for self-contained breathing apparatus (SCBA).
    No change to the rule is necessary. Under this rule, SCBA is 
required for entry into confined spaces containing sawdust or wood 
chips unless the atmosphere in the space has been tested and determined 
to contain sufficient oxygen to support life. In an emergency when 
testing is not possible, entry into an unventilated space is permitted 
only when wearing SCBA. Loading operations are not an emergency. If the 
cargo hold to be loaded with wood chips has been opened and ventilated, 
and has been determined to be safe for human occupancy, there is no 
reason for a worker engaged in loading operations to have to wear SCBA.
    28. Section 148.15. Another comment proposed that the Coast Guard 
establish a fee schedule to issue special permits.
    The Coast Guard does not charge a fee for special permits and does 
not plan to do so.
    29. Section 148.405. One comment recommended that the Coast Guard 
recognize hot work practices for individual companies; specifically, 
approval of hot work by the Chief Engineer.
    No change to the rule is needed. Hot work may be authorized by the 
vessel's master, which by definition includes ``an authorized 
representative of the master.'' A ship's officer, such as the Chief 
Engineer, would fall under this definition of master as proposed in 
Sec.  148.3.
    30. Section 148.407. Three comments stated that it would be 
impractical and unnecessary to prohibit smoking anywhere on a vessel at 
any time.
    We agree with the comments. In this proposed rule, smoking is 
prohibited on the weather deck of the vessel during loading and 
unloading. At all times while cargo is on board, smoking is prohibited 
in adjacent spaces and in the vicinity of hatch covers, ventilator 
outlets, and other accesses to the hold containing the cargo.
    31. Section 148.410. Two comments questioned the need for a shore-
supplied fire main and also the need for fresh water. The ship's 
supply, they stated, is more reliable, particularly in cold weather.
    We agree that the requirement proposed in 1994 exceeds both the 
IMSBC Code and recommended industry practice. We have removed from this 
proposed rule the requirement for fresh water from a shore source.
    32. Section 148.415.
    a. One comment noted that there are no requirements for the gas and 
oxygen analyzers to be calibrated at specified intervals.
    In this proposed rule, we have added a provision to Sec. Sec.  
148.415 and 148.85 specifying that the gas analyzing equipment must be 
calibrated in accordance with the manufacturer's instructions.
    b. One comment stated that there was no sustainable justification 
for exempting unmanned barges from these requirements.
    We disagree and believe there is ample reason to exclude unmanned 
barges from the requirement to have flammable gas analyzers on board. 
First, the proposed rule does not apply to barges carrying PDM, except 
when the barges are on an international voyage. In domestic 
transportation, these materials are normally carried in open hopper 
barges, in which gases emitted by the material would be unlikely to 
reach flammable concentrations. Second, for barges carrying cargoes 
other than PDM, it would be impractical and expensive to require a gas 
analyzer and tubes on each barge. An unmanned barge is not likely to 
have a safe and secure place to stow such delicate and sensitive 
devices. Finally, there is no reason for the crew of a towing vessel to 
enter the cargo space of a barge while underway. Apart from the 
potential danger to personnel working on the deck of a barge in a 
typical multi-barge tow, it would be difficult, if not impossible, to 
remove the hatch covers to gain access for entry.
    33. Section 148.430. One comment agreed with Sec.  148.430 as 
proposed in the 1994 NPRM, but noted that, in some cases, it may mean 
providing some additional SCBA units.
    In this proposed rule, we have removed Sec.  148.430 and 
incorporated its provisions into Sec.  148.85. The substance of the 
observation is correct: At least two SCBA units are required under 
proposed Sec.  148.85 and vessels may carry more if they deem it is 
necessary.
    34. Section 148.450. One comment objected to the inclusion of coal 
as a cargo subject to liquefaction, because liquefaction as a practical 
occurrence cannot occur with coal.
    This issue was addressed earlier under a comment on the entry for 
coal in Table 148.10. Liquefaction can occur in a cargo of coal 
consisting of fine-grained particles. In this proposed rule, this 
section has been revised to specify the maximum particle size of coal 
to which the section applies.

C. Changes Between the 1994 NPRM and This NPRM, Not Prompted by 
Specific Comments

    1. Section 148.3. We added the definition of ``threshold limit 
value'' (TLV), and based the definition on that used by the American 
Conference of Governmental Industrial Hygienists (ACGIH).
    2. Section 148.10. To conform to recent amendments to the IMSBC 
Code, we changed the material description ``aluminum processing 
byproducts'' to ``aluminum smelting byproducts or aluminum remelting 
byproducts.'' For the same reason, we added to Table 148.10 the 
following language under ``Characteristics'' at the entry for 
silicomanganese: ``With known hazard profile or known to evolve gases. 
With silicon content of 25 percent or more.''

[[Page 34584]]

Additionally, we added entries for peat moss and ferrous sulfate to 
Table 148.10 to conform to recent addition to the IMSBC Code.
    3. Section 148.15. We propose to set the maximum term of validity 
for Coast Guard special permits to 4 years. This would reduce the 
paperwork burden for applicants for Coast Guard special permits, and 
would reduce the Coast Guard's administrative burden.
    4. Section 148.145. Paragraphs (b) and (c) of this section, as they 
appeared in the 1994 NPRM, were not stowage or segregation 
requirements, which this section addresses. We have transferred these 
provisions to Sec.  148.300.
    5. Section 148.240. To reflect a recent decision by the IMO, we 
revised paragraphs (e), (h), (i), and (j) to permit the monitoring of 
carbon monoxide emissions as an alternative means of determining rising 
temperature in a cargo of self-heating coal. Also, we lowered the gas 
emission threshold at which corrective action must be initiated from 30 
percent to 20 percent.
    6. Section 148.242. This new section contains special carriage and 
handling requirements for copra, based on the provisions of the IMSBC 
Code.
    7. Section 148.265. Coast Guard Special Permit 14-95 authorizes 
treating fishmeal with a tocopherol (vitamin E) based liquid 
antioxidant in lieu of the antioxidants specified in the former 
regulations. Paragraphs (c) and (e) of this section have been revised 
to include this practice.
    8. Section 148.290. This new section contains special carriage and 
handling provisions for peat moss, based on the provisions of the IMSBC 
Code.
    9. Section 148.300. On September 28, 1995, the U.S. Department of 
Transportation Research and Special Programs Administration (now PHMSA) 
published a rulemaking in Docket HM-169A that made their regulations at 
Title 49 of the CFR governing the transport of radioactive materials 
compatible with the regulations of the International Atomic Energy 
Agency (IAEA). Because 49 CFR 173.403 now contains a definition of 
``Surface Contaminated Object'' (SCO-I), this definition need not 
appear in Coast Guard regulations. Consequently, the term ``Surface 
Contaminated Object'' is defined in Sec.  148.300 by reference to 49 
CFR 173.403.

V. Discussion of Proposed Rule

    The proposed rule would expand the list of materials that may be 
transported in bulk without applying for a special permit and would 
detail the special handling requirements. The new list aligns the CFR 
with mandatory international code, including requirements in Chapter VI 
and Chapter VII of SOLAS. The proposed rule includes materials already 
listed in the IMSBC Code and adds materials that have a safe transport 
history under existing Coast Guard special permits. The proposed rule 
also eliminates applications and renewals for most special permits now 
required when carrying materials regulated under this part.
    This rulemaking would add 21 new materials to 46 CFR part 148. Some 
of these materials are covered by the IMSBC Code, some are covered by 
the HMR (49 CFR chapter I, subchapter C), and some are currently 
subject to Coast Guard special permits.

A. Proposed Changes to Part 97

    This proposed rule would add a definition of ``bulk solid cargo'' 
and revise Subpart 97.12 to clarify that the subpart applies to bulk 
solid cargoes in general, rather than only to ores and ore 
concentrates. The new proposed rule also clarifies that this section 
does not apply to grain, as was the original intent of this part, 
although this was not specified. Further, existing Sec.  97.12-5, which 
has not been revised since 1965, references a manual that was the 
predecessor of the IMSBC Code and is no longer in print. The proposed 
rule eliminates that reference and refers the reader to Part 148 as a 
source of information for complying with the requirement to provide 
guidance on safe loading and stowage to the master.
    We have also added new proposed Sec.  97.12-5 on liquefaction in 
order to bring forward the requirements contained in Sec.  148.450 and 
apply them to all cargoes that are prone to liquefaction. We also 
propose to modify Sec.  97.55-1 to apply to any bulk solid cargo to 
which Sec.  148.435 applies.
    In the proposed rule we have updated the authority citation for 
Part 97 to include 46 U.S.C. 5111 regarding the provision of loading 
information to the master or individual in charge of the vessel.

B. Proposed Changes to Part 148

    We propose to revise the title of 46 CFR part 148 to read 
``Carriage of Bulk Solid Materials that Require Special Handling.'' We 
propose to update the authority citation for Part 148 to include 33 
U.S.C. 1602 and Executive Order 12234 regarding international 
regulations, as well as 46 U.S.C. 3306 and 5111 regarding regulation of 
inspected vessels and provision of loading information to the master or 
individual in charge of the vessel.
    We propose to divide Part 148 into six subparts. Within those 
subparts, the proposed rule reorganizes and renumbers existing sections 
and adds new sections. We discuss these changes in detail below.
1. Proposed Subpart A--General
    The first 12 sections of the revised Part 148 would include general 
information applicable to the entire Part. We propose to revise the 
applicability section (formerly Sec.  148.01-1, now proposed Sec.  
148.1) to align with the IMSBC Code. Specifically, this change would 
apply Part 148 to all foreign-flag and U.S.-flag vessels operating in 
U.S. waters. The proposed regulations would also apply to all classes 
of vessels that transport bulk solid cargoes, including unmanned barges 
and barge-carrying vessels. The regulations would not apply to unmanned 
barges when carrying cargoes classed as PDM in domestic transportation.
    We propose to add a new ``responsibility and compliance'' section 
at Sec.  148.2, making the vessel master, person in charge of a barge, 
owner, operator, charterer, or agent responsible for compliance with 
this part.
    We propose to add a new ``definitions'' section at Sec.  148.3. 
This section would contain definitions that currently are located 
throughout Part 148, as well as new definitions that were included for 
clarity and consistency with the IMSBC Code, including ``away from,'' 
``Bulk Cargo Shipping Name,'' ``compartment,'' ``confined space,'' 
``domestic voyage,'' and ``hazard class.'' We also propose to revise 
the definition of ``bulk'' for clarity and consistency with the IMSBC 
Code.
    We propose to add a new ``alternative procedures'' section at Sec.  
148.5 that outlines the procedures for requesting permission to use 
alternative procedures, including exemptions to the IMSBC Code, in 
place of any requirement of this part. We propose to revise the section 
on permitted cargoes (formerly Sec.  148.01-7, now proposed Sec.  
148.10 and Table 148.10) to improve usability and add additional bulk 
solid cargoes that appear in the IMSBC Code or are authorized under a 
Coast Guard special permit. In revising the table, the Coast Guard 
proposes to add 4 additional columns describing: the identification 
number; a reference to the preferred BCSN, if needed; cargo 
characteristics; and the applicable CFR sections containing detailed 
special requirements for transporting that material. These revisions 
would make it easier to determine the exact

[[Page 34585]]

requirements for carriage of each approved material.
    In Table 148.10, the entry for ``aluminum dross, class PDM'' would 
read ``aluminum processing byproducts or aluminum re-melting 
byproducts, UN 3170, Class 4.3,'' and the entry for ``zinc ashes, 
dross, residues and skimmings'' would read ``zinc ashes, UN 1435, Class 
4.3.'' These changes reflect reclassification of the materials by the 
United Nations Committee of Experts on the Transport of Dangerous 
Goods. In addition, the revised table would add the following to the 
list of permitted cargoes, to maintain consistency with the IMSBC Code 
and current Coast Guard special permits: aluminum ferrosilicon powder; 
aluminum silicon powder, uncoated, brown coal briquettes; castor beans; 
coal; DRI (A); DRI (B); environmentally hazardous substances, solid, 
n.o.s.; ferrous sulfate, fluorospar; iron oxide, spent, or iron sponge, 
spent; linted cotton seed; magnesia, unslaked; metal sulfide 
concentrates; peat moss with moisture content of more than 65 percent 
by weight; pitch prill; pyrites, calcined; seed cake; silicomanganese 
with silicon content of 25 percent or more; vanadium ore; and wood 
chips, wood pellets, and wood pulp pellets.
    We further propose to add a new section on hazardous or potentially 
dangerous characteristics at Sec.  148.11. This section would 
incorporate information currently contained in column 3 of the table of 
permitted cargoes. The new section would set forth the meaning of the 
``hazardous or potentially dangerous characteristics'' codes given in 
the revised Table 148.10. This includes code 27, a reference to the 
Certain Dangerous Cargoes (CDC) regulations found in 33 CFR 160.204, 
that apply to ammonium nitrate.
    Finally, we propose to renumber the existing Sec.  148.01-13, 
``Assignment and certification,'' as Sec.  148.12.
2. Proposed Subpart B--Special Permits
    As proposed, Subpart B would set the guidelines for petitions and 
use of special permits. The proposed revisions to Subpart A should 
greatly reduce the need for special permits. However, in the event a 
person wishes to ship a bulk solid material not listed in Table 148.10, 
the proposed Subpart B allows that person to petition for authorization 
from the Coast Guard. The revised process for requesting a special 
permit remains substantively similar to the existing process, but 
places more responsibility on the shipper to determine the appropriate 
conditions of carriage. The proposed Subpart B also clarifies who must 
apply for a special permit, what information is required to obtain a 
special permit, what activities are covered by a special permit, how 
long a special permit remains valid, and how to obtain copies of 
special permits. These proposed sections are more detailed than the 
current regulations, and are designed to resolve recurring 
misunderstandings concerning the applicability of the special permit. 
In addition, requiring applicants to submit more detailed information 
about the material carried would greatly decrease the amount of 
research time needed by the Coast Guard when processing requests for 
special permits.
    Included within the proposed Subpart B is a revision of existing 
Sec.  148.01-11 designed to simplify the standard conditions contained 
in special permits, and to renumber it as Sec. Sec.  148.15 through 
148.30. In addition, the Coast Guard proposes to remove the current 
Sec.  148.01-11(b)(1) because it describes requirements imposed by 
special permits.
3. Proposed Subpart C--Minimum Transportation Requirements
    As proposed, Subpart C would outline minimum transportation 
requirements for cargoes subject to this chapter, including temperature 
readings, shipping paper requirements, emergency response information, 
DCMs, preparation and supervision of cargo transfers, confined space 
entry and equipment, preparations for loading, procedures after 
unloading, log book entries, and incident reports.
    The Coast Guard proposes to clarify the proper conduct of 
temperature readings (formerly Sec.  148.03-7, now proposed Sec.  
148.51), and to require log book entries (proposed Sec.  148.90) to 
record each temperature measurement and each required test for toxic or 
flammable gases.
    The Coast Guard also proposes to revise shipping paper requirements 
(formerly Sec.  148.02-1, now Sec.  148.60) to align with the IMSBC 
Code while requiring the shipping papers be provided in English. With 
regard to emergency response information, the Coast Guard proposes new 
Sec.  148.61 requiring that the shipper of a material listed in Table 
148.10 provide the master or his representative with appropriate 
emergency response information, including preliminary first aid 
measures and emergency procedures to be carried out in the event of an 
incident or fire involving the cargo. Provision of an MSDS would 
satisfy this requirement.
    With regard to DCMs (formerly Sec.  148.02-3, now proposed 
Sec. Sec.  148.70 through 148.72), the Coast Guard proposes to revise 
the requirements for carriage and contents of the DCM. As proposed, the 
DCM requirements would not apply to unmanned barges not on 
international voyages.
    With regard to confined space entry and equipment, the Coast Guard 
proposes new Sec.  148.85, which would require that vessels, with the 
exception of unmanned barges, that carry a material listed in Table 
148.10 also carry equipment capable of measuring atmospheric oxygen and 
at least two approved SCBA that each have at least a 30-minute air 
supply. Proposed Sec.  148.86 would prohibit entry into a confined 
space unless the space has been tested to ensure there is sufficient 
oxygen to support life; in case of emergency, a person may enter a 
confined space without testing it if that person is wearing a SCBA, 
suitable protective clothing as necessary, and a wire rope safety line 
tended by a trained person outside the space, and if the entry is 
supervised by a responsible person.
    With regard to procedures to be followed after unloading, the Coast 
Guard proposes to renumber existing Sec.  148.03-13 as Sec.  148.110 
and revise it to require retention and proper disposal of cargo-
associated wastes, cargo residue, and deck sweepings when in U.S. 
territorial seas or inland waters.
    In addition, the Coast Guard proposes to add new Sec.  148.55 
``International Shipments,'' which would enable the use of the IMSBC 
Code as an alternate method of compliance with Part 148, as long as the 
bulk solid material being transported is subject to the requirements of 
the IMSBC Code. However, transport of zinc ashes must comply with Part 
148 because zinc ashes pose environmental hazards that would not 
otherwise be addressed. In addition, the proposed Sec.  148.55 would 
include new paragraphs (b)(3) and (b)(4) to require Coast Guard 
approval of any exemption granted by another government before reliance 
on that exemption for compliance with Part 148. Finally, Sec.  148.55 
would make the person importing a bulk solid responsible for ensuring 
the foreign shipper is aware of U.S. requirements.
4. Proposed Subpart D--Stowage and Segregation
    Proposed Subpart D would set stowage and segregation requirements 
for cargoes. These proposed requirements are in addition to the minimum 
requirements for all materials and the general requirements for their 
respective hazard classes contained in Subpart A. The Coast Guard 
proposes to require segregation of cargoes from

[[Page 34586]]

incompatible materials as shown in new Tables 148.120A and B. These 
tables present the requirements for, respectively, segregating 
incompatible bulk solid cargoes, and segregating bulk solid cargoes 
from incompatible packaged cargoes. The segregation requirements set 
out in Tables 148.120A and B are based on a rational approach 
established by the IMO, and are identical to the IMSBC Code. The Coast 
Guard proposes additional stowage and segregation requirements, 
detailed by class, in the remainder of Subpart D.
5. Proposed Subpart E--Special Requirements for Certain Materials
    Proposed Subpart E would set forth special requirements for certain 
hazardous materials, including ammonium nitrate, DRI, seed cake, and 
zinc ashes. For clarity, the requirements are presented in tabular form 
at new proposed Table 148.155. Many of the requirements are drawn from 
the IMSBC Code, or are required already under applicable special 
permits. The addition of Table 148.155 will reduce the number of 
special permits issued and harmonize these regulations with the IMSBC 
Code.
    In addition to listing special requirements for certain hazardous 
materials, this subpart proposes requirements for bulk shipment of 
hazardous substances as defined by PHMSA regulations at 49 CFR 171.8, 
which in turn are based on Environmental Protection Agency (EPA) 
regulations implementing the Comprehensive Environmental Response, 
Compensation, and Liability Act (CERCLA). The EPA classifies materials 
as hazardous substances based on the material's potential to endanger 
public health or welfare, or the environment, if the material is 
accidentally released. Materials classified as hazardous substances 
under 49 CFR 172.101, Table 1 to Appendix A, previously were carried 
only pursuant to special permits on a case-by-case basis. This section 
would not relieve the shipper or the master from any of the reporting 
requirements set forth in 40 CFR part 302, but would set out minimum 
requirements for the safe carriage of solid hazardous substances in 
bulk.
    Within Subpart E, the Coast Guard proposes to revise current Sec.  
148.04-13 so that a vessel may not leave port unless the Captain of the 
Port (COTP) is satisfied that the temperature of ferrous metal is 
within the limits set by the applicable provisions of this section. The 
current regulation merely specifies that the COTP must be notified if 
the temperature exceeds those limits.
    In the specific context of petroleum coke, the Coast Guard proposes 
to combine two existing sections (Sec. Sec.  148.04-15 and 148.04-17) 
into one section at Sec.  148.295. The proposed requirements at new 
Sec.  148.295 align with the IMSBC Code and already are required under 
applicable special permits.
    With regard to radioactive materials, the Coast Guard proposes to 
revise the current Sec.  148.04-1 as Sec.  148.300 and align it with 
the IMSBC Code, which has re-defined low specific activity (LSA) 
radioactive materials and added a new entry for SCO-I. As a result, the 
proposed regulations would apply to surface contaminated objects.
    In the specific context of seed cake, we have proposed to exempt 
from this regulation citrus pulp pellets containing not more than 2.5 
percent oil and a maximum of 14 percent oil and moisture combined. Our 
decision was based on extensive testing at various moisture and oil 
levels from several countries currently transporting the product. It 
was found that within these limits, the product should not be 
considered a hazardous material.
    Although the Coast Guard intends to harmonize U.S. regulations with 
the IMSBC Code, the proposed Sec.  148.330, which applies to zinc 
ashes, zinc dross, zinc residues, and zinc skimmings in bulk, would 
differ significantly from the IMSBC Code. As proposed, Sec.  148.330 
requires COTP notification in advance of any cargo transfer operations 
involving these cargoes. The provisions of this section are based on 
two Coast Guard special permits, SP 8-83 and SP 4-84, which we 
developed as the result of incidents involving fires or explosions in 
cargoes of zinc skimmings, including at least one with loss of life. 
The intent of this section would be to reduce the possibility of 
generating hydrogen gas through the reaction of seawater and zinc. 
Therefore, the aging, storage, and temperature requirements in this 
proposed section exceed those in the IMSBC Code. Both the IMSBC Code 
and the proposed regulations require mechanical ventilation, explosion-
proof fans, and installed thermocouples for temperature gauging in the 
cargo hold.
6. Proposed Subpart F--Additional Special Requirements
    Proposed column 7 of Table 148.10, ``Special Requirements,'' refers 
readers to other sections containing additional requirements. Many of 
those sections are contained in proposed Subpart F, which would set 
forth requirements for safety equipment and procedures when handling 
certain cargoes. The types of special requirements that may apply to 
certain cargoes include: prohibition on sources of ignition including, 
in some cases, smoking or electrical circuits; a requirement that fire 
hoses be available at each hatch through which a covered material is 
being loaded; requirements for toxic gas and flammable gas analyzers 
and testing; stowage precautions; and special precautions for cargoes 
subject to liquefaction.
    With regard to cargoes subject to liquefaction, the Coast Guard's 
proposed rule results from specific experience. On April 11, 1991, off 
the California coast, a foreign-flag vessel that had loaded a bulk 
solid material in a U.S. port developed a severe list when the cargo 
shifted. Fortunately, this vessel was able to return to port and off-
load. The Coast Guard investigation determined that the cargo shifted 
because its moisture content exceeded the safe Transportable Moisture 
Limit (TML). This condition caused the material to behave like a 
liquid. Because of this marine casualty and others of a similar nature, 
the Coast Guard proposes to add new Sec.  148.450 to prescribe 
requirements for transporting bulk solids that are subject to 
liquefaction. These proposed rules are adapted from the IMSBC Code and 
only apply to calcined pyrites, fluorospar, fine particle coal, metal 
sulfide concentrates, and peat moss, as indicated in Table 148.10, and 
to other cargoes that exhibit the potential for liquefaction as 
indicated by information provided to the master in accordance with 
97.12-3. The proposed rules would not apply to shipments by unmanned 
barges or cargoes of coal that have an average particle size of 10 mm 
(0.394 in) or greater. The moisture content and TML may be determined 
using test procedures in Appendix 2 of the IMSBC Code.

C. Distribution Table for Part 148

    The Coast Guard proposes to replace existing Part 148 with a 
completely revised and renumbered Part 148. The following distribution 
table shows which sections of the proposed rule address the substance 
of each existing section.

VI. Incorporation by Reference

    Material proposed for incorporation by reference appears in Sec.  
148.8 of the proposed rule. You may inspect this material at U.S. Coast 
Guard Headquarters where indicated under ADDRESSES. Copies of the 
material are available from the sources listed in Sec.  148.8.
    Before publishing a binding rule, we will submit this material to 
the Director of the Federal Register for approval of the incorporation 
by reference.

VII. Regulatory Analyses

    We developed this proposed rule after considering numerous statutes 
and executive orders related to rulemaking. Below we summarize our 
analysis based on 13 of these statutes or executive orders.

A. Regulatory Planning and Review

    This proposed rule is not a significant regulatory action under 
section 3(f) of Executive Order 12866, Regulatory Planning and Review, 
and does not require an assessment of potential costs and benefits 
under section 6(a)(3) of that Order. The Office of Management and 
Budget (OMB) has not reviewed it under that Order.
    A combined ``Preliminary Regulatory Assessment and Initial 
Regulatory Flexibility Analysis'' report discussing the impact of this 
proposed rule is available in the docket where indicated under 
ADDRESSES. A summary of the report follows:
    The Coast Guard proposes to harmonize its regulations with recent 
IMO amendments to Chapter VI and Chapter VII of SOLAS that make the 
IMSBC Code mandatory for operations involving handling and carriage of 
solid bulk cargoes by vessel. The amendments require that all vessels 
subject to SOLAS that carry bulk solid cargoes other than grain to 
comply with the IMSBC Code. This proposed rule also would amend the 
Coast Guard regulations governing the carriage of solid hazardous 
materials in bulk to allow use of the IMSBC as an equivalent form of 
compliance. Proposed changes to the Coast Guard regulations would also 
expand the list of solid hazardous materials authorized for bulk 
transportation by vessel and include special handling procedures based 
on the IMSBC Code and existing special permits. These proposed changes 
would reduce the need for the current special permits required for the 
carriage of certain solid hazardous materials in bulk and result in a 
cost savings to industry.
    The IMSBC Code facilitates safe stowage and shipment of solid bulk 
cargoes. It provides information on the dangers associated with 
shipping certain types of solid bulk cargoes and instructions on 
procedures for handling said cargoes. The IMSBC Code will be mandatory 
under the amendments to the SOLAS Convention as of January 1, 2011.
Affected Population
    Based on information from the Coast Guard's Marine Information for 
Safety and Law Enforcement (MISLE) data system, we estimate the 
proposed rule would affect approximately 115 vessels, consisting of 75 
U.S. vessels in coastwise service and 40 U.S. vessels operating under 
SOLAS that ship hazardous solid cargoes in bulk.
Costs
    We estimate the proposed rule would result in additional equipment, 
training, and operating costs to industry. Under the provisions of this 
proposed rule, each vessel would be required to have onboard non-
sparking fans, an oxygen meter, a carbon monoxide meter, a temperature 
probe, two SCBA, goggles and a dust mask, and a multi-gas detector. We 
estimate that industry would incur equipment costs during the 
implementation period (Year 1) of $2.7 million undiscounted. We also 
estimate there will be annual recurring costs due to equipment 
maintenance and replacement (see the Preliminary Regulatory Analysis 
report available in the docket for additional details).
    The use of the equipment described above would require additional 
training. We estimate industry would incur initial training costs in 
the first year of $33,900 and annual recurring training costs due to 
labor turnover of about $6,800 each year thereafter (estimates 
undiscounted). Operating costs would consist of testing, recording 
keeping, and vessel preparation. The equipment described above would be 
used to periodically test the temperature and atmospheric conditions of 
certain cargoes. All tests and readings must be recorded, and the date 
and time of testing recorded in the vessel's log book. We estimate 
industry would incur an annual recurring operating cost of $7.4 million 
undiscounted.
Cost Savings
    This proposed rule would also result in cost savings to certain 
vessels, as preparation of permit renewals will no longer be needed. We 
estimate this regulation would reduce the need for ten permit requests 
per year. Based on information provided in the OMB-approved Information 
Collection Request (Carriage of Bulk Solid Materials Requiring Special 
Handling: 1625-0025), annual cost savings for both industry and 
government are estimated at $15,390 undiscounted.
    Table 1 below provides the net costs (adjusted for savings) of this 
proposed rule. We estimate the undiscounted first-year cost of the 
rulemaking to be about $10.1 million. Over a 10-year period, the total 
present value costs of the proposed rule would be $57.2 million at a 7 
percent discount rate and $69.3 million at a 3 percent discount rate.

                                          Table 1--Total 10-Year Costs

----------------------------------------------------------------------------------------------------------------
Note: Totals include cost savings.

Benefits
    In this rulemaking, the Coast Guard anticipates that benefits would 
include a reduction in the risks associated with off-gassing and self-
heating cargoes. These proposed standards are comprehensive safety 
requirements that would align with international regulations (the IMSBC 
Code), and are intended to increase information dissemination regarding 
the safe handling of hazardous cargoes.
    These safety standards would extend to all U.S.-flagged vessels 
carrying hazardous bulk solid cargoes. A lack of safe handling of 
hazardous cargoes, such as coal or wood, can cause combustion of 
cargoes and the release of gases that could result in the loss of life, 
injuries, and property damage, among others. The proposed rule would 
also improve the efficiency of government by reducing the 
administrative costs associated with special permit applications.

B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have 
considered whether this proposed rule would have a significant economic 
impact on a substantial number of small entities. The term ``small 
entities'' comprises small businesses, not-for-profit organizations 
that are independently owned and operated and are not dominant in their 
fields, and governmental jurisdictions with populations of less than 
50,000.
    A combined ``Preliminary Regulatory Assessment and Initial 
Regulatory Flexibility Analysis'' report discussing the impact of this 
proposed rule on small entities is available in the docket where 
indicated under the ``Public Participation and Request for Comments'' 
section of this preamble. A summary of this report follows:
    For this proposed rule, we reviewed size and ownership data of 
affected entities by using the Coast Guard's MISLE database and public 
and proprietary data sources for company revenue and employee size 
data. We determined that 86 entities own the 115 vessels that would be 
impacted by this regulation. We found revenue and employment 
information on 33 of the 86 entities. We found that all affected 
entities would be businesses. Among these, eight would be considered 
small entities under the Small Business Administration (SBA) standard. 
We take a conservative approach by assuming vessels listed as 
``unspecified'' and those with no available information are small (of 
which there are 52). Therefore, we estimate that 70 percent of the 
entities meet the SBA standards of a small entity.
    Using the highest single year cost (Year 1) in the Total 10-Year 
Costs table above, we estimate that 75 percent of the small entities 
would have an annual cost impact of greater than or equal to 3 percent 
of annual revenue.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that the proposed 
regulation will have a significant economic impact on it, please submit 
a comment to the Docket Management Facility at the address under 
ADDRESSES. In your comment, explain why you think it qualifies and how 
and to what degree this proposed rule will economically affect it.

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 proposed rule so that they can better 
evaluate its effects on them and participate in the rule. If the 
proposed rule would affect your small business, organization, or 
governmental jurisdiction and you have questions concerning its 
provisions or options for compliance, please contact Richard Bornhorst 
at the telephone number or e-mail address indicated under the FOR 
FURTHER INFORMATION CONTACT section of this notice. 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 proposed rule would revise an existing 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 
collection, a description of those who must collect the information, 
and an estimate of the change in annual burden follow. The estimated 
change covers the time for preparing or renewing permit requests for 
hazardous solid bulk cargoes.
    Under the conditions of the proposed rule, vessels and barge 
companies would no longer submit special permit renewal requests to the 
U.S. Coast Guard. Handling requirements related to previously permitted 
cargoes would be part of 46 CFR part 148. Eliminating these permits 
would reduce the burden associated with 1625-0025 by reducing the 
number of respondents, responses, and burden hours associated with 
permits requests.
    Title: Carriage of Bulk Solid Materials Requiring Special Handling.

[[Page 34589]]

    OMB Control Number: 1625-0025.
    Summary of the Collection of Information: The U.S. Coast Guard 
administers and enforces the law, regulations, and international 
conventions for the safe transportation and stowage of hazardous 
materials, including bulk solids. Consequently, the Coast Guard is 
authorized to issue special permits for the handling of hazardous solid 
bulk cargo as part of its missions to ensure maritime safety and 
facilitate U.S. commerce. In addition to special permits, this 
collection of information also authorizes the preparation and display 
of shipping papers and cargo manifests. However, the proposed rule will 
change only the burden estimates associated with special permits.
    Need for Information: The Special Permits allow the Coast Guard to 
control the conditions under which shipments of hazardous materials can 
be made, while giving the shipping industry a greater amount of 
flexibility than would be afforded without the Special Permit 
provision. If the required information were not submitted, the Coast 
Guard would be unable to issue Special Permits with adequate 
precautions for shipping the cargo, and thus could not permit shipment.
    Proposed Use of Information: The Coast Guard uses this information 
to make a well-informed determination as to the severity of the hazard 
posed by the material in question. This information allows the Coast 
Guard to set specific guidelines for safe carriage or, if determined 
that a material presents too great a hazard, to deny permission for 
shipping the material.
    Description of the Respondents: The respondents are owners and 
operators of bulk carrier vessels and barges carrying hazardous solid 
cargo.
    Number of Respondents: The existing OMB-approved number of 
respondents for this collection, including permit requests, shipping 
papers, and cargo manifest, is 583. We estimate the number of 
respondents will decrease by seven as the proposed rule eliminates the 
need for all but one special permit. The total number of respondents 
would be 576.
    Number of Responses: The existing OMB-approved number of responses 
is 771. The proposed rule would decrease that number by 10. The total 
number of responses would be 761 per year as a result of a decrease in 
special permit requests.
    Frequency of Response: The proposed regulation will not alter the 
frequency of response for permits that remain active. Since this 
regulation does not impact shipping papers or cargo manifests, 
frequency of responses for those items remain unchanged.
    Burden of Response: The estimated burden for preparation of a 
permit request remains at 15 hours per permit.
    Estimate of Total Annual Burden: This regulation will eliminate the 
need for all but one of the special permits associated with this 
collection of information. Therefore, the annual burden associated with 
special permits will decline from 165 hours to 15 hours. The total 
burden for the collection of information, including cargo manifests and 
shipping papers, decreases from 895 hours to 745 hours per year.
    Reason for Change: The decrease in burden is the result of a 
program change that eliminates the need for most of the special permits 
in this collection of information.
    As required by the Paperwork Reduction Act of 1995 (44 USC 
3507(d)), we have submitted a copy of this proposed rule to the OMB for 
its review of the collection of information.
    We ask for public comment on the proposed collection of information 
to help us determine how useful the information is; whether it can help 
us perform our functions better; whether it is readily available 
elsewhere; how accurate our estimate of the burden of collection is; 
how valid our methods for determining burden are; how we can improve 
the quality, usefulness, and clarity of the information; and how we can 
minimize the burden of collection.
    If you submit comments on the collection of information, submit 
them both to OMB and to the Docket Management Facility where indicated 
under ADDRESSES, by the date under DATES.
    You need not respond to a collection of information unless it 
displays a currently valid control number from OMB. Before the 
requirements for this collection of information become effective, we 
will publish a notice in the Federal Register of OMB's decision to 
approve, modify, or disapprove the collection.

E. Federalism

    A rule has implications for federalism under Executive Order 13132, 
Federalism, if it has a substantial direct effect on State or local 
governments and would either preempt state law or impose a substantial 
direct cost of compliance on them.
    It is well settled that States may not regulate in categories 
reserved for regulation by the Coast Guard. It is also well settled, 
now, 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 
(Mar. 6, 2000)).
    This proposed rule includes requirements under which certain solid 
materials requiring special handling may be transported in bulk by 
vessel. The revised regulations apply to all domestic and foreign 
vessels in the navigable waters of the United States that transport 
bulk solid materials requiring special handling. The authority to 
establish such regulations for vessels operating in the navigable 
waters of the United States has been committed to the Coast Guard by 
Federal statutes. Furthermore, since vessels tend to move from port to 
port in the national and international marketplace, the safety 
standards included in this rule are of national scope to avoid 
burdensome variances. Therefore, the Coast Guard intends this rule to 
preempt state action addressing the same subject matter.
    Because the states may not regulate within this category, 
preemption considerations set forth in Executive Order 13132 are not 
applicable.

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 1 year. Though this proposed rule would not 
result in such an expenditure, we do discuss the effects of this rule 
elsewhere in this preamble.

G. Taking of Private Property

    This proposed rule would not cause a taking of private property or 
otherwise have taking implications under Executive Order 12630, 
Government Actions and Interference with Constitutionally Protected 
Property Rights.

H. Civil Justice Reform

    This proposed rule meets applicable standards in sections 3(a) and 
3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize 
litigation,

[[Page 34590]]

eliminate ambiguity, and reduce burden.

I. Protection of Children

    We have analyzed this proposed rule under Executive Order 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 proposed rule does not have tribal implications under 
Executive Order 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 proposed rule under Executive Order 13211, 
Actions Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use. We have determined that it is not a ``significant 
energy action'' under that order because it is not a ``significant 
regulatory action'' under Executive Order 12866 and is not likely to 
have a significant adverse effect on the supply, distribution, or use 
of energy. The Administrator of the Office of Information and 
Regulatory Affairs has not designated it as a significant energy 
action. Therefore, it does not require a Statement of Energy Effects 
under Executive Order 13211.

L. Technical Standards

    The National Technology Transfer and Advancement Act (NTTAA) (15 
U.S.C. 272 note) directs agencies to use voluntary consensus standards 
in their regulatory activities unless the agency provides Congress, 
through the Office of Management and Budget, 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 proposed rule incorporates by reference the IMSBC Code, which 
was developed by the IMO as a voluntary consensus standard. The 
proposed sections that reference this voluntary consensus standard and 
the locations where this standard is available are listed in the 
proposed 46 CFR 148.8.

M. Environment

    We have analyzed this proposed rule under Department of Homeland 
Security Directive 023-01 and Commandant Instruction M16475.lD, which 
guide the Coast Guard in complying with the National Environmental 
Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have made a 
preliminary determination that this action is one of a category of 
actions that do not individually or cumulatively have a significant 
effect on the human environment. Therefore, this rule is categorically 
excluded under section 2.B.2. Figure 2-1, paragraphs 34(c), (d), and 
(e), of the Instruction, and neither an environmental assessment nor an 
environmental impact statement is required. This rule affects crew 
training, inspection and equipping of vessels, equipment approval and 
carriage requirements. A preliminary ``Environmental Analysis Check 
List'' supporting this determination is available in the docket where 
indicated under the ``Public Participation and Request for Comments'' 
section of this preamble. We seek any comments or information that may 
lead to the discovery of a significant environmental impact from this 
proposed rule.

Subpart A--General


Sec.  148.1  Purpose and applicability.

    (a) This part prescribes special handling procedures for certain 
solid materials that present hazards when transported in bulk by 
vessel.
    (b) Except as noted in paragraph (c) of this section, this part 
applies to all domestic and foreign vessels in the navigable waters of 
the U.S that transport bulk solid materials requiring special handling.
    (c) This part does not apply to an unmanned barge on a domestic 
voyage carrying a Potentially Dangerous Material (PDM) found in Table 
148.10 of this part. All barges on international voyages must follow 
the requirements for PDM.
    (d) The regulations in this part have preemptive impact over State 
law on the same subject. The Coast Guard has determined, after 
considering the factors developed by the Supreme Court in U.S. v. 
Locke, 529 U.S. 89 (2000), that in directing the Secretary to regulate 
the safe transportation of hazardous material and the safety of 
individuals and property on board vessels subject to inspection, as 
well as the provision of loading information, Congress intended to 
preempt the field of safety standards for solid materials requiring 
special handling when transported in bulk on vessels.


Sec.  148.2  Responsibility and compliance.

    Each master of a vessel, person in charge of a barge, owner, 
operator, shipper, charterer, or agent must ensure compliance with this 
part. These persons are also responsible for communicating requirements 
to every person performing any function covered by this part.


Sec.  148.3  Definitions.

    As used in this part--
    A-60 class division means a division as defined in Sec.  32.57-5 of 
this chapter.
    Adjacent space means any enclosed space on a vessel, such as a 
cargo hold, cargo compartment, accommodation space, working space, 
storeroom, passageway, or tunnel, that shares a common bulkhead or deck 
with a hatch, door, scuttle, cable fitting or other penetration, with a 
cargo hold or compartment containing a material listed in Table 148.10 
of this part.
    Away from means a horizontal separation of at least 3 meters (10 
feet) projected vertically is maintained between incompatible materials 
carried in the same hold or on deck.
    Bulk applies to any solid material, consisting of a combination of 
particles, granules, or any larger pieces of material generally uniform 
in composition, that is loaded directly into the cargo spaces of a 
vessel without any intermediate form of containment.
    Bulk Cargo Shipping Name or BCSN identifies a bulk solid material 
during transport by sea. When a cargo is listed in this Part, the BCSN 
of the cargo is identified by Roman type and is listed in Column 1 of 
Table 148.10 of this part. When the cargo is a hazardous material, as 
defined in 49 CFR part 173, the proper shipping name of that material 
is the BCSN.
    Cold-molded briquettes are briquettes of direct reduced iron (DRI) 
that have been molded at a temperature of under 650 [deg]C (1202 
[deg]F) or that have a density of under 5.0 g/cm[sup3].
    Commandant (CG-5223) means the Chief, Hazardous Materials Standards 
Division of the Office of Operating and Environmental Standards, United 
States Coast Guard, 2100 2nd St., SW., Stop 7126, Washington, DC 20593-

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

    Hazardous substance is a hazardous substance as defined in 49 CFR 
171.8.
    Hold means a compartment below deck that is used exclusively for 
the stowage of cargo.
    Hot-molded briquettes are briquettes of DRI that have been molded 
at a temperature of 650 [deg]C (1202 [deg]F) or higher, and that have a 
density of 5.0 g/cm\3\ (312 lb/ft\3\) or greater.
    IMSBC Code means the English version of the ``International 
Maritime Solid Bulk Cargoes Code'' published by the International 
Maritime Organization (incorporated by reference, see Sec.  148.8).

1910.1200.
    Person in charge of a barge means an individual designated by the 
owner or operator of a barge to have charge of the barge.
    Potentially dangerous material or PDM means a material that does 
not fall into a particular hazard class but can present a danger when 
carried in bulk aboard a vessel. The dangers often result from the 
material's tendency to self-heat or cause oxygen depletion. Materials 
that present a potential danger due solely to their tendency to shift 
in the cargo hold are not PDMs. For international shipments prepared in

                                Hazardous or potentially dangerous
          Code                            characteristic
------------------------------------------------------------------------
1.......................  Contact with water may cause heating.
2.......................  Contact with water may cause evolution of
                           flammable gases, which may form explosive
                           mixtures with air.
3.......................  Contact with water may cause evolution of
                           toxic gases.
4.......................  If involved in a fire, will greatly intensify
                           the burning of combustible materials.
5.......................  A major fire aboard a vessel carrying this
                           material may involve a risk of explosion in
                           the event of contamination (e.g., by a fuel
                           oil) or strong confinement. If heated
                           strongly will decompose, giving off toxic
                           gases that support combustion.
6.......................  These mixtures may be subject to self-
                           sustaining decomposition if heated.
                           Decomposition, once initiated, may spread
                           throughout the remainder, producing gases
                           that are toxic.
7.......................  Toxic if swallowed and by dust inhalation.
8.......................  Harmful and irritating by dust inhalation.

Subpart D--Stowage and Segregation


Sec.  148.120  Stowage and segregation requirements.

    (a) Each material listed in Table 148.10 of this part must be 
segregated from incompatible materials in accordance with--
    (1) The requirements of Tables 148.120A and 148.120B of this 
section that pertain to the primary or subsidiary hazard class to which 
the materials belong. Whenever a subsidiary hazard may exist, the most 
stringent segregation requirement applies; and
    (2) Any specific requirements in Subpart D of this part.
    (b) Materials that are required to be separated during stowage must 
not be handled at the same time. Any residue from a material must be 
removed before a material required to be separated from it is loaded.
    (c) Definitions and application of segregation terms:
    (1) ``Separated from'' means located in different cargo 
compartments or holds when stowed under deck. If the intervening deck 
is resistant to fire and

[[Page 34600]]

liquid, a vertical separation, i.e., in different cargo compartments, 
is acceptable as equivalent to this segregation.
    (2) ``Separated by a complete cargo compartment or hold from'' 
means either a vertical or horizontal separation, for example, by a 
complete cargo compartment or hold. If the intervening decks are not 
resistant to fire and liquid, only horizontal separation is acceptable.
    (3) ``Separated longitudinally by an intervening complete cargo 
compartment or hold from'' means that vertical separation alone does 
not meet this requirement.

    (i) Measuring the temperature of the coal;
    (ii) Measuring the emission of carbon monoxide; or
    (iii) Both.
    (f) If coal waiting to be loaded has a potential to emit dangerous 
amounts of methane, for example it is freshly mined, or has a history 
of emitting dangerous amounts of methane, then:
    (1) Surface ventilation, either natural or from fixed or portable 
nonsparking fans, must be provided; and
    (2) The atmosphere above the coal must be monitored for the 
presence of methane as prescribed in paragraph (h) of this section. The

explosive gas atmosphere. The master of the vessel must ensure that the 
affected equipment and cables remain de-energized as long as this coal 
remains in the hold.
    (h) For all coal loaded on a vessel, other than an unmanned barge, 
the atmosphere above the coal must be routinely tested for the presence 
of methane, carbon monoxide, and oxygen, following the procedures in 
the Appendices to the schedules for Coal and Brown Coal Briquettes as 
contained in the IMSBC Code (incorporated by reference, see Sec.  
148.8). This testing must be performed in such a way that the cargo 
hatches are not opened and entry into the hold is not necessary.
    (i) When carrying a coal described in paragraph (e) of this 
section, the atmosphere above the coal must be monitored for the 
presence of carbon

[[Page 34604]]

monoxide as prescribed in paragraph (h) of this section. The results of 
this monitoring must be recorded at least twice in every 24-hour 
period, unless the conditions of paragraph (m) of this section are met. 
If the level of carbon monoxide is increasing rapidly or reaches 20 
percent of the lower flammability limit (LFL), the frequency of 
monitoring must be increased.
    (j) When a cargo of coal has a potential to self-heat or has been 
observed to be heating, the hatches should be closed and sealed and all 
surface ventilation halted except as necessary to remove any methane 
that may have accumulated.
    (k) If the level of carbon monoxide monitored under paragraph (i) 
of this section continues to increase rapidly or the temperature of 
coal carried on board a vessel exceeds 55 [deg]C (131 [deg]F) and is 
increasing rapidly, the master must notify the nearest Coast Guard 
Captain of the Port of--
    (1) The name, nationality, and position of the vessel;
    (2) The most recent temperature, if measured, and levels of carbon 
monoxide and methane;
    (3) The port where the coal was loaded and the destination of the 
coal;
    (4) The last port of call of the vessel and its next port of call; 
and
    (5) What action has been taken.
    (l) If the level of methane as monitored under paragraph (h) of 
this section reaches 20 percent of the LFL or is increasing rapidly, 
ventilation of the cargo hold, under paragraph (f) of this section, 
must be initiated. If this ventilation is provided by opening the cargo 
hatches, care must be taken to avoid generating sparks.
    (m) The frequency of monitoring required by paragraph (l) of this 
section may be reduced at the discretion of the master provided that--
    (1) The level of gas measured is less than 20 percent of the LFL;
    (2) The level of gas measured has remained steady or decreased over 
three consecutive readings, or has increased by less than 5 percent 
over four consecutive readings spanning at least 48 hours; and
    (3) Monitoring continues at intervals sufficient to determine that 
the level of gas remains within the parameters of paragraphs (n)(1) and 
(n)(2) of this section.

    (b) No person may enter a cargo hold containing wood chips, wood 
pellets, or wood pulp pellets, unless--
    (1) The atmosphere in the cargo hold has been tested and contains 
enough oxygen to support life; or
    (2) The person entering the cargo hold is wearing the appropriate 
self-contained breathing apparatus.


Sec.  148.330  Zinc ashes; zinc dross; zinc residues; zinc skimmings.

    (a) The shipper must inform the cognizant Coast Guard Captain of 
the Port in advance of any cargo transfer operations involving zinc 
ashes, zinc dross, zinc residues, or zinc skimmings (collectively, 
``zinc material'') in bulk.
    (b) Zinc material must be aged by exposure to the elements for at 
least one year before shipment in bulk.
    (c) Before loading in bulk, zinc material must be stored under 
cover for a period of time to ensure that it is as dry as practical. No 
zinc material that is wet may be accepted for shipment.
    (d) Zinc material may not be loaded in bulk if its temperature is 
greater than 11.1 [deg]C (52 [deg]F) in excess of the ambient 
temperature.
    (e) Paragraphs (e)(1) through (e)(5) of this section apply only 
when zinc materials are carried by a cargo vessel:
    (1) Zinc material in bulk must be stowed in a mechanically 
ventilated hold that--
    (i) Is designed for at least one complete air change every 30 
minutes based on the empty hold;
    (ii) Has explosion-proof motors approved for use in Class I, 
Division 1, Group B atmospheres or equivalent motors approved by the 
vessel's flag state administration for use in hydrogen atmospheres; and
    (iii) Has nonsparking fans.
    (2) Combustible gas detectors capable of measuring hydrogen 
concentrations of 0 to 4.1 percent by volume must be permanently 
installed in holds that will carry zinc material. If the concentration 
of hydrogen in the space above the cargo exceeds 1 percent by volume, 
the ventilation system must be run until the concentration drops below 
1 percent by volume.
    (3) Thermocouples must be installed approximately 6 inches below 
the surface of the zinc material or in the space immediately above the 
zinc material. If an increase in temperature is detected, the 
mechanical ventilation system required by paragraph (d) of this section 
must be used until the temperature of the zinc material is below 55 
[deg]C (131 [deg]F).
    (4) Except as provided in paragraph (e)(5) of this section, the 
cargo hatches of holds containing zinc material must remain sealed to 
prevent the entry of seawater.
    (5) If the concentration of hydrogen is near 4.1 percent by volume 
and increasing, despite ventilation, or the temperature of the zinc 
material reaches 65 [deg]C (150 [deg]F), the cargo hatches should be 
opened provided that weather and sea conditions are favorable. When 
hatches are opened take care to prevent sparks and minimize the entry 
of water.

Subpart F--Additional Special Requirements


Sec.  148.400  Applicability.

    Unless stated otherwise, the requirements of this subpart apply 
only to the shipment or loading of materials, listed in Table 148.10 of 
this part, for which Table 148.10 contains a reference to a section or

    When Table 148.10 of this part associates a material with a 
reference to this section, and that material is being loaded or 
unloaded, smoking is prohibited anywhere on the weatherdeck of the 
vessel. While such a material is on board the vessel, smoking is 
prohibited in spaces adjacent to the cargo hold and on the vessel's 
deck in the vicinity of cargo hatches, ventilator outlets, and other 
accesses to the hold containing the material. ``NO SMOKING'' signs must 
be displayed in conspicuous locations in the areas where smoking is 
prohibited.


Sec.  148.410  Fire hoses.

    When Table 148.10 of this part associates a material with a 
reference to this section, a fire hose must be available at each hatch 
through which the material is being loaded.


Sec.  148.415  Toxic gas analyzers.

    When Table 148.10 of this part associates a material with a 
reference to a paragraph in this section, each vessel transporting the 
material, other than an unmanned barge, must have on board a gas 
analyzer appropriate for the toxic gas listed in that paragraph. At 
least two members of the crew must be knowledgeable in the use of the 
equipment. The equipment must be maintained in a condition ready for 
use and calibrated according to the instructions of its manufacturer. 
The atmosphere in the cargo hold and adjacent spaces must be tested 
before a person is allowed to enter these spaces. If toxic gases are 
detected, the space must be ventilated and retested before entry. The 
toxic gases for which the requirements of this section must be met are:
    (a) Arsine,
    (b) Carbon monoxide,
    (c) Hydrogen cyanide,
    (d) Hydrogen sulfide,
    (e) Phosphine, and
    (f) Sulfur dioxide.


Sec.  148.420  Flammable gas analyzers.

    When Table 148.10 of this part associates a material with a 
reference to a paragraph in this section, each vessel transporting the 
material, other than an unmanned barge, must have on board a gas 
analyzer appropriate for the flammable gas listed in that paragraph. At 
least two members of the crew must be knowledgeable in the use of the 
equipment. The equipment must be maintained in a condition ready for 
use, capable of measuring 0 to 100 percent LFL for the gas indicated, 
and calibrated in accordance with the instructions of its manufacturer. 
The atmosphere in the cargo hold must be tested before any person is 
allowed to enter. If flammable gases are detected, the space must be 
ventilated and retested before entry. The flammable gases for which the 
requirements of this section must be met are:

    (c) Methane.


Sec.  148.435  Electrical circuits in cargo holds.

    During transport of a material that Table 148.10 of this part 
associates with a reference to this section, each electrical circuit 
terminating in a cargo hold containing the material must be 
electrically disconnected from the power source at a point outside of 
the cargo hold. The point of disconnection must be marked to prevent 
the circuit from being reenergized while the material is on board.


Sec.  148.445  Adjacent spaces.

    When transporting a material that Table 148.10 of this part 
associates with a reference to this section, the following requirements 
must be met:
    (a) Each space adjacent to a cargo hold must be ventilated by 
natural ventilation or by ventilation equipment safe for use in an 
explosive gas atmosphere;
    (b) Each space adjacent to a cargo hold containing the material 
must be regularly monitored for the presence of the flammable gas 
indicated by reference to Sec.  148.420. If the level of flammable gas 
in any space reaches 30 percent of the LFL, all electrical equipment 
that is not certified safe for use in an explosive gas atmosphere must 
be de-energized at a location outside of that space. This location must 
be labeled to prohibit reenergizing until the atmosphere in the space 
is tested and found to be less than 30 percent of the LFL;
    (c) Each person who enters any space adjacent to a cargo hold or 
compartment containing the material must wear a self-contained 
breathing apparatus unless--
    (1) The space has been tested, or is routinely monitored, for the 
appropriate flammable gas and oxygen;
    (2) The level of flammable gas is less than 10 percent of the LFL; 
and
    (3) The level of toxic gas, if required to be tested, is less than 
the TLV;
    (d) No person may enter an adjacent space if the level of flammable 
gas is greater than 30 percent of the LFL. If emergency entry is 
necessary, each person who enters the space must wear a self-contained 
breathing apparatus and caution must be exercised to ensure that no 
sparks are produced.


Sec.  148.450  Cargoes subject to liquefaction.

    (a) This section applies only to cargoes identified in Table 148.10 
of this part with a reference to this section and cargoes identified in 
the IMSBC Code (incorporated by reference, see Sec.  148.8) as cargoes 
that may liquefy.
    (b) This section does not apply to--
    (1) Shipments by unmanned barge; or
    (2) Cargoes of coal that have an average particle size of 10mm 
(.394 in.) or greater.
    (c) Definitions as used in this section--
    (1) Cargo subject to liquefaction means a material that is subject 
to moisture migration and subsequent liquefaction if shipped with 
moisture content in excess of the transportable moisture limit.
    (2) Moisture migration is the movement of moisture by settling and 
consolidation of a material, which may result in the development of a 
flow state in the material.
    (3) Transportable moisture limit or TML of a cargo that may liquefy 
is the maximum moisture content that is considered safe for carriage on 
vessels.
    (d) Except on a vessel that is specially constructed or specially 
fitted for the purpose of carrying such cargoes (see also section 7 of 
the IMSBC Code, incorporated by reference, see Sec.  148.8), a cargo 
subject to liquefaction may not be transported by vessel if its 
moisture content exceeds its TML.
    (e) The shipper of a cargo subject to liquefaction must give the 
master the material's moisture content and TML.
    (f) The master of a vessel shipping a cargo subject to liquefaction 
must ensure that--
    (1) A cargo containing a liquid is not stowed in the same cargo 
space with a cargo subject to liquefaction; and
    (2) Precautions are taken to prevent the entry of liquids into a 
cargo space containing a cargo subject to liquefaction.

[[Page 34609]]

    (g) The moisture content and TML of a material may be determined by 
the tests described in Appendix 2, Section 1, of the IMSBC Code 
(incorporated by reference, see Sec.  148.8).
