III. Executive Summary

    When writing regulations that set technical standards, the Coast 
Guard relies as much as possible on existing industry consensus 
standards. Doing so minimizes proliferation of differing standards and 
complies with the National Technology Transfer and Advancement Act and 
OMB Circular A-119. The legal method of directing

regulated entities to follow separately published standards is called 
incorporation by reference (IBR). This notice of proposed rulemaking 
(NPRM) proposes to update prior incorporations by reference, add a 
limited number of alternative standards, and eliminate outdated or 
unnecessarily prescriptive regulations in title 46 of the Code of 
Federal Regulations (CFR) subchapter J.
    This proposed rule would update the standards incorporated by 
reference (IBR) in both 46 CFR 110.10-1 and all of the sections in 
subchapter J that reference the updated IBR standards. More 
specifically, this proposed rule would incorporate the more recent 
editions of many standards, incorporate by reference additional 
standards for certain topics, and remove IBR standards that are no 
longer actively used by industry. Due to technological advances, it is 
necessary to update the current standards to ensure modern technologies 
are addressed in the regulations. In addition to updating the IBR 
standards, we propose the following four changes to subchapter J.
    First, this proposed rule would eliminate the prescriptive 
requirements in 46 CFR 111.12-1(b) and (c) for generator prime movers. 
In accordance with 46 CFR 58.01-5, these generator prime movers would 
continue to be required to meet standards of the American Bureau of 
Shipping (ABS) Steel Vessel Rules.
    Second, this proposed rule would simplify the electrical cable 
construction requirements in subpart 111.60 so they are similar to the 
classification society requirements currently accepted without 
supplement under the Coast Guard's Alternate Compliance Program.
    Third, for classifications of hazardous locations in subpart 
111.105, this proposed rule would accept the International 
Electrotechnical Commission's (IEC) 60092-502 as an alternative 
classification. This is an internationally accepted standard and we are 
not aware of any notable casualty history attributed to its use as 
compared to vessels complying with the current applicable U.S. 
regulations for classification of hazardous locations.
    Fourth, this proposed rule would amend 46 CFR 112.05 to allow the 
use of an emergency generator in port. This optional capability to use 
emergency generators in port would be acceptable if a set of additional 
safeguards, approved by the International Maritime Organization (IMO) 
in 2005 are provided to ensure the availability of emergency power.
    The following table provides an overview of the types of proposed 
changes and the affected sections.

IV. Basis and Purpose

    The legal basis of this proposed rulemaking is section 1333(d) of 
Title 43, United States Code (U.S.C.), sections 3306 and 3703 of Title 
46 U.S.C., and the Department of Homeland Security (DHS) Delegation No. 
0170.1. The provisions of 43 U.S.C. 1333(d) grant the Secretary of the 
Department in which the Coast Guard is operating the authority to 
promulgate and enforce regulations with respect to lights and other 
warning devices, safety equipment, and other matters relating to the 
promotion of safety of life and property on artificial islands, 
installations, and other devices. Section 46 U.S.C. 3306(a)(1) 
authorizes the Secretary to prescribe regulations for the design, 
construction, alteration, repair, and operation of vessels subject to 
inspection, including equipment, appliances, propulsion machinery, 
auxiliary machinery, boilers, unfired pressure vessels, piping, and 
electric installations. Additionally, 46 U.S.C. 3703 grants the 
Secretary authority to regulate the construction, alteration, repair, 
maintenance, operation, and equipping of vessels, that may be necessary 
for increased protection against hazards to life and property, for 
navigation and vessel safety, and for enhanced protection of the marine 
environment. These authorities have been delegated to the Coast Guard 
by the DHS Security Delegation No. 0170.1(II)(92)(b).
    The purpose of this proposed rulemaking is to update the standards 
that are incorporated by reference in 46 CFR subchapter J, which 
provide detailed specifications for electrical equipment used by 
vessels. Newly published editions of the international standards 
referenced in subchapter J address new technologies and changes in best 
practices. The Office of Management and Budget (OMB) Circular A-119 
states agencies should undertake a review of the standards incorporated 
by reference every 3 to 5 years to remain current with technological 
changes. OMB encourages reducing reliance on unique government 
standards when an existing voluntary consensus standard would suffice. 
This proposed rule follows the Circular by incorporating newer editions 
of industry standards and reducing the reliance on unique Coast Guard 
standards where industry standards are sufficient.

V. Background

    Title 46 CFR subchapter J contains the electrical engineering 
regulations and standards applicable to vessels and required shipboard 
systems regulated under subchapters D, H, I, I-A, K, L, O, Q, R, T, U, 
and W of Title 46. A key component of subchapter J is the standards 
that are incorporated by reference (IBR) in 46 CFR 110.10-1 and cross-
referenced throughout parts 110, 111, 112, and 113. The IBR section in 
subchapter J was last amended by the 2015 final rule titled 
``Electrical Equipment in Hazardous Locations'' (80 FR 16980, Mar. 31, 
2015), but because of its limited scope, that rule did not update all 
of the standards to reflect newer editions. Many of the IBR standards 
have not been updated since 2008 when the Coast Guard issued the final 
rule titled ``Review and Update of Standards for Marine Equipment'' (73 
FR 65156, Oct. 31, 2008).
    Furthermore, the interim rule titled ``Offshore Supply Vessels of 
at Least 6,000 GT ITC'' (79 FR 48893, Aug. 18, 2014) and the 
``Electrical Equipment in Hazardous Locations'' final rule (80 FR 
16980, Mar. 31, 2015) amended subchapter J by adding the hazardous 
location regulations in subparts 111.106 and 111.108 for types of 
vessels and facilities not covered under subpart 111.105. Vessels and 
facilities regulated under 111.106 and 111.108 have a broader and more 
current selection of IBR standards because there were more recent 
standards to include with those rulemakings. This proposed rule would 
amend subparts 111.105, 111.106 and 111.108 to ensure all vessel types 
are offered the broadest and most current selection of IBR explosion 
protection standards.
    Shipboard electrical systems are becoming increasingly complex due 
to the development of power electronics and computer control systems. 
In response, many of the standards incorporated by reference have been 
superseded by newer editions to address the newer electrical equipment. 
In some cases, the later editions reflect more modern technologies, 
terminology, and practices that are already in use by industry. 
Adopting newer versions of these standards would reduce the number of 
equivalency requests from industry to the Coast Guard, which is 
expected to produce cost savings. The incorporation of more recent 
editions also ensures the latest industry practices and advancements in 
technology are addressed in regulations.

VI. Discussion of Proposed Rule

A. Proposed Revisions to Sec.  110.10-1 Incorporation by Reference

    Currently, all of the standards that are incorporated by reference 
in subchapter J are listed in Sec.  110.10-1. Within this section, the 
Coast Guard proposes to update the technical standards to reflect the 
more recent editions of the standards available to the public. We 
encourage the use of these updated standards because they reflect the 
best available technologies, practices, and procedures that are 
recommended by consensus bodies and other groups with experience in the 
industry. As the baseline upon which other standards, rules, and 
equivalency requests are evaluated, it is important that subchapter J 
incorporates up-to-date references.
    The class rules of the American Bureau of Shipping (ABS), in 
particular, are incorporated by reference in multiple locations within 
subchapter J and throughout 46 CFR Chapter I. It is important to note 
that while these rules set the regulatory baseline or standard for 
specific engineering systems and equipment, the Coast Guard also 
designated several other authorized classification societies in 
accordance with 46 CFR part 8. These classification societies are 
listed on the Coast Guard website.\1\ The Coast Guard authorized the 
listed classification societies to perform certain functions and 
certifications using their respective class rules on vessels enrolled 
in the Alternate Compliance Program. Vessels not enrolled in the 
Alternate Compliance Program may propose using the class rules of an 
authorized classification society as an alternative to the ABS class 
rules incorporated by reference for particular engineering systems and 
equipment in accordance with Sec.  110.20-1.
---------------------------------------------------------------------------

    \1\ See https://www.dco.uscg.mil/Our-Organization/Assistant-Commandant-for-Prevention-Policy-CG-5P/Inspections-Compliance-CG-5PC-/Commercial-Vessel-Compliance/Flag-State-Control-Division/ClassSocAuth/.
---------------------------------------------------------------------------

    Throughout Sec.  110.10-1, we also propose additional standards to 
provide alternative compliance options, remove outdated standards, and 
clarify existing requirements. Where applicable, this proposed rule 
would also update the naming format, mailing addresses, phone numbers, 
and URL addresses for the standards already incorporated by reference. 
These updates will ensure that the standards are reasonably accessible 
to the public.
    Following this paragraph, we list the standards we propose to 
update, add, or delete in Sec.  110.10-1. Within each standard listed, 
we describe the topics covered by the standard, the proposed changes to 
the standard, any differences between currently incorporated IBR 
standards, and a list of the subparts or sections that reference the 
IBR standard. If this proposed rule does not propose any changes to a 
standard that is

[[Page 21443]]

currently incorporated by reference, the standard will not be discussed 
in the proposed revisions to Sec.  110.10-1. However, it will be 
included, without change, in the proposed regulatory text that appears 
at the end of this document.
     ABS Rules for Building and Classing Marine Vessels (ABS 
Marine Vessel Rules), 2020. The ABS is a vessel classification society 
that develops and publishes rules for the construction and maintenance 
of ships and offshore facilities. Subchapter J references these rules 
in numerous sections as an option for the design of certain systems 
including generators, semiconductor rectifiers, and electric propulsion 
systems. Specifically, we currently reference the 2003 edition in 
Sec. Sec.  110.15-1(b), 111.01-9(b), 111.12-3, 111.12-5, 111.12-7, 
111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n), 111.105-39(a), 
111.105-40, and 113.05-7(a). In 2020, ABS transitioned from the ABS 
Steel Vessel Rules to the ABS Marine Vessel Rules. This allowed ABS to 
consolidate several rules into one foundational rule. We propose to 
incorporate by reference the 2020 ABS Marine Vessel Rules in the 
aforementioned sections and additionally in the new proposed Sec.  
112.05-7(c) related to use of emergency generators in port. The ABS 
Marine Vessel Rules undergo an annual review and approval process by 
ABS technical committees. The Coast Guard participates on these 
committees, which are comprised of international experts with relevant 
experience. Several of the sections of the ABS Marine Vessel Rules that 
we propose to incorporate by reference have been individually updated. 
For example:
    [cir] ABS Marine Vessel Rules 4-8-3/Table 2: This table specifies 
minimum degrees of protection for electrical equipment. This updated 
table contains several technical updates since 2003 edition, including 
additional notes concerning areas protected by fixed water-spray or 
water mist fire extinguishing systems, and equipment subject to water 
splash.
    [cir] ABS Marine Vessel Rules 4-8-3: We reference this section for 
generator construction requirements. The updated edition contains 
technical updates to account for changes in technology since the 2003 
edition.
    [cir] ABS Marine Vessel Rules 4-8-5/5.17.9: This section regarding 
semiconductor rectifiers now requires a high temperature alarm.
    [cir] ABS Marine Vessel Rules 4-8-5/5.5: This edition contains 
updates to propulsion generator requirements.
    [cir] ABS Marine Vessel Rules 4-8-2/9.17: This edition updates the 
requirements for protection of motor circuits to address athwartship 
thruster motor load alarms and more clearly defines the systems 
requiring undervoltage release.
    [cir] ABS Marine Vessel Rules 4-8-3/5: This updated section 
regarding switchboards and motor controllers contains additional cable 
connection requirements, optional alternative creepage and clearance 
distances, and additional requirements on battery and uninterruptible 
power systems based on advancements in technology.
    [cir] ABS Marine Vessel Rules 5-10-4/3: This section regarding 
roll-on/roll-off cargo spaces is now titled 5C-10-4/3. The new edition 
made updates to ventilation requirements and to the tables of dangerous 
goods.
    [cir] ABS Marine Vessel Rules 4-9-7/Table 9: This table regarding 
equipment testing is now titled 4-9-8/Table 1. The updates to this 
table reflect changes in technology and industry testing practices.
     ABS Rules for Building and Classing Mobile Offshore Units 
(ABS MOU Rules), Part 4 Machinery and Systems, 2020. ABS also develops 
and publishes rules for the construction and maintenance of mobile 
offshore drilling units. Subchapter J references these rules in 
numerous sections as an option for design of certain systems including 
generator, semiconductor rectifier, and electric propulsion systems. 
Specifically, we currently reference the 2001 edition in Sec. Sec.  
111.12-1(a), 111.12-3, 111.12-5, 111.12-7(c), 111.33-11, 111.35-1, and 
111.70-1(a). In 2020, ABS transitioned from the ABS Mobile Offshore 
Drilling Units Rules to the ABS MOU Rules. This allowed ABS to 
consolidate several rules into one foundational rule. We propose to 
incorporate by reference the 2020 ABS MOU Rules. Like the ABS Marine 
Vessel Rules, the ABS MOU Rules will undergo a regular review and 
approval process by the ABS technical committees comprised of 
international experts with relevant experience. ABS updated and changed 
the title of several of the ABS MOU rules incorporated by reference in 
these sections. For example:
    [cir] ABS MOU Rules 4-3-4 (renamed ABS MOU Rules 6-1-7): We 
reference this section regarding generator construction requirements. 
ABS made several technical updates since the 2001 edition to account 
for changes in technology.
    [cir] ABS MOU Rules 4-3-4/3.5.3 (renamed 6-1-7/12): We reference 
this section, for semiconductor converters requirements. ABS made 
several updates to the standard due to changes in technology.
    [cir] ABS MOU Rules 4-3-4/7.1 (renamed 6-1-7/9.9): We reference 
this section regarding bus bars and wiring requirements. ABS made 
several updates to the section since the 2001 edition.
     American National Standards Institute (ANSI) and Institute 
of Electrical and Electronic Engineers (IEEE) ANSI/IEEE C37.12-1991--
American National Standard for Alternating Current (AC) High-Voltage 
Circuit Breakers Rated on a Symmetrical Current Basis-Specifications 
Guide. We propose to remove this standard from Sec.  111.54-1 because 
IEEE changed the title and republished it with updates in 2008 as IEEE 
C37.12-2008--IEEE Guide for Specifications of High-Voltage Circuit 
Breakers (over 1,000 Volts), 2008. This represented a complete 
technical revision of the standard. IEEE subsequently revised it again 
in 2018. We are proposing to incorporate by reference IEEE C37.12-2018 
in Sec.  111.54-1 and further discuss this standard with the other IEEE 
standards incorporated by reference.
     ANSI/IEEE C37.27-1987 (IEEE 331)--Application Guide for 
Low-Voltage AC Nonintegrally Fused Power Circuitbreakers (Using 
Separately Mounted Current-Limiting Fuses). We are proposing to remove 
the reference to this standard in Sec.  111.54-1 because this guide was 
replaced by IEEE C37.27-2015--IEEE Guide for Low-Voltage AC (635 V and 
below) Power Circuit Breakers Applied with Separately-Mounted Current-
Limiting Fuses, 2015. We discuss this standard, IEEE C37.27-2015, with 
the other IEEE standards incorporated by reference.
     ANSI/International Society of Automation (ISA) 12.12.01-
2015--Nonincendive Electrical Equipment for Use in Class I and II, 
Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) 
Locations. The purpose of this standard is to provide minimum 
requirements for the design, construction, and marking of electrical 
equipment or parts of such equipment for use in Class I and Class II, 
Division 2 and Class III, Divisions 1 and 2 hazardous (classified) 
locations. This newer edition of the standard would replace ANSI/ISA 
12.12.01-2012 which the Coast Guard recently added to Sec.  111.108-
3(b) as part of a separate rulemaking titled ``Electrical Equipment in 
Hazardous Locations'' (80 FR 16980, Mar. 31, 2015). Additionally, we 
propose to include ANSI/ISA 12.12.01-2015 in Sec. Sec.  111.105-7(a) 
and 111.106-3(b) as another certification option for electrical 
equipment in hazardous location. The 2015 edition contains

[[Page 21444]]

minor technical changes from the 2012 edition.
     ANSI/ISA-60079-18--Explosive atmospheres--Part 18: 
Equipment protection by encapsulation ``m'', Third Edition, 2012. This 
standard gives the specific requirements for the construction, testing, 
and marking of electrical equipment and parts of electrical equipment, 
and for the designation of explosion-protected electrical apparatus 
complying with IEC standards (Ex) components (which is part of an 
electrical equipment module found in the European hazardous area 
scheme) with the type of protection encapsulation ``m'' intended for 
use in explosive gas atmospheres or explosive dust atmospheres. We 
currently reference the 2009 edition of this standard in Sec.  111.106-
3(d), and the 2012 edition in Sec.  111.108-3(e). This proposed rule 
would remove the ANSI/ISA-60079-18 references in Sec. Sec.  111.106-
3(d) and 111.108-3(e) because it has been withdrawn and replaced by UL 
60079-18, a substantively similar standard. We propose replacing the 
ANSI/ISA standard with UL 60079-18 in Sec.  111.106-3(d) and 111.108-
3(e).
     American Petroleum Institute (API) Recommended Practice 
API RP 14F--Recommended Practice for Design, Installation, and 
Maintenance of Electrical Systems for Fixed and Floating Offshore 
Petroleum Facilities for Unclassified and Class 1, Division 1 and 
Division 2 Locations, Sixth Edition, October 2018. This document 
recommends minimum requirements and guidelines for the design, 
installation, and maintenance of electrical systems on fixed and 
floating petroleum facilities located offshore. We propose to reference 
clause 6.8 of the document in Sec.  111.105-17. This clause provides 
guidance on use of conduit, cable seals, and sealing methods. The 
incorporation of this standard would add another wiring option in 
hazardous locations.
     API RP 14FZ--Recommended Practice for Design, 
Installation, and Maintenance of Electrical Systems for Fixed and 
Floating Offshore Petroleum Facilities for Unclassified and Class I, 
Zone 0, Zone 1 and Zone 2 Locations, Second Edition, May 2013. This 
document recommends minimum requirements and guidelines for the design, 
installation, and maintenance of electrical systems on fixed and 
floating petroleum facilities located offshore. We propose to reference 
clause 6.8 of the document in Sec.  111.105-17. This clause provides 
guidance on use of conduit, cable seals, and sealing methods. The 
incorporation of this standard would add another wiring option in 
hazardous locations.
     API RP 500--Recommended Practice for Classification of 
Locations for Electrical Installations at Petroleum Facilities 
Classified as Class I, Division 1 and Division 2, Third Edition, 
December 2012. This recommended practice provides guidelines for 
classifying locations at petroleum facilities as Class I, Division 1 
and Class I, Division 2 locations for the selection and installation of 
electrical equipment. We currently reference the second edition (1997) 
of this standard in Sec. Sec.  111.106-7(a) and 111.106-13(b). We 
propose to reference the more recent, third edition (2012) in those 
sections. The 2012 edition contains editorial changes, but the 
technical content has not changed.
     API RP 505--Recommended Practice for Classification of 
Locations for Electrical Installations at Petroleum Facilities 
Classified as Class I, Zone 0, Zone 1, and Zone 2, Second Edition, 
August 2018. The purpose of this recommended practice is to provide 
guidelines for classifying locations Class I, Zone 0, Zone 1, and Zone 
2 at petroleum facilities for the selection and installation of 
electrical equipment. We currently reference the first edition, which 
was published in 1997 and reaffirmed in 2013, in Sec.  111.106-7(a) and 
111.106-13(b). We propose to reference the more recent, second edition 
(2018) in those sections. This will not substantively change to the 
requirements of those sections.
     American Society of Mechanical Engineers (ASME) A17.1-
2016/CSA B44-16--Safety Code for Elevators and Escalators, 2016. This 
code covers the design, construction, operation, inspection, testing, 
maintenance, alteration, and repair of elevators, hoists, escalators 
and their associated parts, rooms, and spaces. We currently reference 
the sixteenth edition (2000) in Sec.  111.91-1. We propose to reference 
the more recent, twenty-first edition (2016) in that section. ASME 
updated this standard based on changes in technology. The updated 
standard addresses new types of elevators being used in the industry, 
specifically wind turbine elevators and outside emergency elevators. In 
addition, the standard contains new requirements to address a new 
feature called ``Elevator Evacuation Operation'' that allows for the 
use of elevators for occupant evacuation. Moreover, there are several 
major changes to the standard that include seismic requirements, 
updated maintenance control program requirements, and revisions 
regarding qualifications for elevator inspectors. ASME A17 has been an 
industry accepted standard since 1921. Although many of the changes to 
the presently incorporated edition of the standard do not apply to 
shipboard elevators, it is important that shipboard elevators meet the 
updated provisions that do apply.
     ASTM International (ASTM) B117-19--Standard Practice for 
Operating Salt Spray (Fog) Apparatus, 2019. This practice covers the 
apparatus, procedure, and conditions required to create and maintain 
the salt spray (fog) test environment. Where the Coast Guard's 
regulations require material to be corrosion resistant it must meet the 
testing requirements of this ASTM standard practice. We currently 
reference the 1997 edition in Sec.  110.15-1(b). We propose to 
reference the current 2019 edition. The 1997 edition has been 
superseded by several subsequent editions. The testing specifications 
in the 2011 edition are similar to those in the 1997 edition, but the 
2011 edition is more detailed. For example, the impurity restrictions 
are more detailed in section 8, the air supply requirements are more 
specific in section 9, and the conditions in the salt chamber are more 
precisely described in section 10. The 2016 edition added a warning 
about the impact of water conductivity in section 4 while the 2019 
edition added several minor but non-substantive explanatory sections. 
Overall, the 2019 edition of this testing standard practice for 
operating salt spray apparatus is very similar to the 1997 edition 
currently incorporated, with minor improvements in the specifications 
to ensure testing consistency and precision.
     ASTM F2876-10--Standard Practice for Thermal Rating and 
Installation of Internal Combustion Engine Packages for use in 
Hazardous Locations in Marine Applications, Reapproved 2015. This 
practice covers the method of testing, rating and installing internal 
combustion engine packages for use in hazardous areas in marine 
applications. We currently reference the 2010 edition of this standard 
in Sec. Sec.  111.106-3(h) and 111.108-3(g). We also propose to 
reference the 2010 edition in newly proposed Sec.  111.105-28 regarding 
internal combustion engines. This will ensure a consistent standard for 
these installations on all vessel and facility types.
     Canadian Standards Association (CSA) C22.2 No. 30-M1986--

Reaffirmed 2016. This standard covers the details of construction and 
tests for explosion-proof enclosures for electrical

[[Page 21445]]

equipment to be used in Class I, Division 1, Groups A, B, C, and D 
hazardous locations and in gaseous mines. We currently reference the 
1986 edition of this standard in Sec. Sec.  111.106-3(b) and 111.108-
3(b) and propose to incorporate the reaffirmed version therein. The two 
versions are not substantively different. We propose to also reference 
this reaffirmed standard in Sec.  111.105-7(a), regarding approved 
equipment, as an additional compliance option. This will afford the 
broadest and most current selection of IBR explosion protection 
standards for all vessel and facility types.
     CSA C22.2 No. 213-16--Nonincendive electrical equipment 
for use in class I, division 2 hazardous locations, May 2016. This 
standard applies to electrical equipment for use in Class I and II, 
Division 2 and Class III, Division 1 and 2 hazardous locations. We 
currently reference the 1987 edition in Sec. Sec.  111.106-3(b) and 
111.108-3(b). We propose to reference the 2016 edition in these 
sections and also reference it in Sec.  111.105-7(a) concerning 
approved equipment. This standard received a major revision since the 
1987 edition based on advances in technology and changes to related 
standards. It is an accepted national standard and one of several 
available standards for nonincendive electrical equipment. Our 
incorporation of this updated edition ensures use of latest industry 
practices and including it in Sec.  111.105-7 will ensure that 
standards are consistent for electrical installations on all vessel and 
facility types.
     CSA-C22.2 No. 0-10--General requirements--Canadian 
Electrical Code, Part II, Reaffirmed 2015. This standard covers 
definitions, construction requirements, marking, and tests of a general 
nature that applies to all or several of the individual standards of 
the Canadian Electrical Code. We currently reference the ninth edition 
of this standard in Sec. Sec.  111.106-3(b) and 111.108-3(b). We 
propose to reference the tenth edition, reaffirmed in 2015, in these 
sections and in Sec.  111.105-7(a) concerning approved equipment. The 
tenth edition includes new requirements for equipment containing lasers 
or lithium batteries, criteria for the use of adhesives in the 
construction of electrical equipment, surface temperature limits, 
attachment plug loading, and the maximum temperature of equipment in 
contact with gypsum. Additionally, it incorporates a comprehensive list 
of definitions for use in standards for electrical products and 
outlines the relationship between this standard and electrical product 
standards. We propose incorporating the more recent edition in subpart 
111.105 to ensure that standards are consistent for electrical 
installations on all vessel and facility types.
     Canadian National Standard (CAN)/CSA-C22.2 No. 157-92--
Intrinsically safe and nonincendive equipment for use in hazardous 
locations, reaffirmed 2016. This standard specifies the testing of 
nonincendive electrical equipment and the details of construction and 
tests for intrinsically safe electrical equipment for use in hazardous 
locations. We currently reference the 1992 edition of this standard in 
Sec. Sec.  111.106-3(b) and 111.108-3(b). We propose to reference the 
reaffirmed 1992 edition in those sections as well as Sec.  111.105-7(a) 
concerning approved equipment. The two editions of the standard are not 
substantively different and incorporating it into Sec.  111.105-7 would 
provide an additional option for vessels and facilities.
     MIL-DTL-24640C with Supplement 1--Detail Specification 
Cables, Lightweight, Low Smoke, Electric, for Shipboard Use, General 
Specification for, Nov. 18, 2011. This specification covers 
lightweight, low smoke, electric cables for Navy shipboard 
applications. MIL-DTL-24640C is already incorporated by reference and 
approved for Sec.  111.106-5(a). However, MIL-DTL-24640C supersedes 
MIL-C-24640A (1996), currently referenced in Sec. Sec.  111.60-1 and 
111.60-3. We propose to incorporate the updated edition, MIL-DTL-24640C 
(2011), into Sec.  111.60-1 only, because this proposed rule would 
delete Sec.  111.60-3. The updated edition, published in 2011, 
incorporates the latest developments in marine cable materials and 
performance enhancements but will not substantively change 
requirements.
     MIL-DTL-24643C with Supplement 1A--Detail Specification 
Cables, Electric, Low Smoke Halogen-Free, for Shipboard Use, General 
Specification for, Oct. 1, 2009 (including Supplement 1A dated Dec. 13, 
2011). This specification is already incorporated by reference in Sec.  
111.106-5(a) and covers low smoke halogen-free electric cable for Navy 
shipboard applications. This specification supersedes the currently 
referenced MIL-C-24643A (1996) incorporated by reference in Sec. Sec.  
111.60-1 and 111.60-3. We propose to delete MIL-C-24643A (1996) and 
incorporate the latest standard MIL-DTL-24643C (2011) into Sec.  
111.60-1 only, because this proposed rule would delete Sec.  111.60-3. 
This updated edition, published in 2011, incorporates the latest 
developments in marine cable materials and performance enhancements.

apply to all indoor and outdoor types of AC high-voltage circuit 
breakers rate above 1000 volts (V). It replaces ANSI/IEEE C37.12-1991. 
IEEE C37.12-2018 represents a nearly complete rewrite of 1991 edition 
to reflect present circuit breaker manufacturing technology. The 2018 
edition of this standard would be one of several acceptable circuit 
breaker standards listed in Sec.  111.54-1.
     IEEE C37.13-2015--IEEE Standard for Low-Voltage AC Power 
Circuit Breakers Used in Enclosures, 5 Dec. 2015. This standard 
establishes minimal functional requirements, establishes preferred 
rating structure, and provides preferred ratings enclosed low-voltage 
AC power circuit breakers. We currently reference the 2000 edition of 
this standard in Sec.  111.54-1. We propose to reference the more 
recent 2015 edition in Sec.  111.54-1. This edition has many technical 
updates to address advancements in technology, including an increase in 
nominal voltages, new testing techniques, and removal of information on 
direct current (DC) circuit-breakers (now located in IEEE C37.14). This 
standard is one of several acceptable circuit-breaker standards in 
Sec.  111.54-1.
     IEEE C37.14-2015--IEEE Standard for DC (3200 V and below) 
Power Circuit Breakers Used in Enclosures, 26 Mar. 2015. This standard 
covers the preferred ratings and testing requirements of enclosed DC 
power circuit breakers. We currently reference the 2003 edition of this 
standard Sec.  111.54-1. We propose to reference the more recent 2015 
edition in Sec.  111.54-1, which contains many technical changes to 
reflect present circuit breaker manufacturing technology and 
advancements in technology.
     IEEE C37.27-2015--IEEE Guide for Low-Voltage AC (635 V and

selection of current-limiting fuses for use in combination with low-
voltage AC power circuit breakers. This guide replaces ANSI/IEEE 
C37.27-1987 which we currently reference in Sec.  111.54-1. IEEE 
C37.27-2015 contains many technical updates to address advancements in 
circuit breaker manufacturing technology, which would provide the 
public with more accurate and applicable standards for modern circuit 
breakers than the previous 1987 edition. We propose incorporating this 
guide as one of several acceptable circuit breaker standards listed in 
Sec.  111.54-1.
     IEEE 45-1998--IEEE Recommended Practice for Electric 
Installations on Shipboard--1998. IEEE 45-2002 superseded the subject 
1998 edition, but in some instances the Coast Guard previously found 
the 1998 edition preferable and continued to reference it. Because the 
1998 edition is no longer supported by IEEE and other acceptable 
standards exist where it is referenced, we propose to delete all 
references to this standard, which includes Sec. Sec.  111.30-19, 
111.105-3, 111.105-31, and 111.105-41.
     IEEE 45-2002--IEEE Recommended Practice for Electrical

     IEEE 45.6-2016--IEEE Recommended Practice for Electrical 
Installations on Shipboard--Electrical Testing, 7 Dec. 2016. This 
recommended practice provides guidance for electrical testing for power 
generation, distribution, and electric propulsion systems. These 
recommendations reflect the present day technologies, engineering 
methods, and engineering practices. We propose to reference this 
document in Sec.  111.60-21. Its technical content is similar to IEEE 
45-2002, which we propose to delete from this section.
     IEEE 45.7-2012--IEEE Recommended Practice for Electrical 
Installations On Shipboard--AC Switchboards, 29 Mar. 2012. This 
recommended practice supplements the design, installation, and testing 
recommendations in IEEE 45-2002. This recommended practice provides new 
technologies and design practices for generator control panels and 
switchboards to aid marine electrical engineers in the design, 
application and installation of this equipment on ships and other 
marine installations. We propose to reference this document in 
Sec. Sec.  111.30-1, 111.30-5, and 111.30-19. The technical content of 
IEEE 45.7-2012 is similar to IEEE 45-2002, but more detailed. It also 
references other industry standards, many of which we have incorporated 
by reference elsewhere in Subchapter J, rather than using prescriptive 
requirements.
     IEEE 45.8-2016--IEEE Recommended Practice for Electrical 
Installations On Shipboard--Cable Systems, 29 Jan. 2016. This document 
provides recommendations for selection, application, and installation 
of electrical power, signal, control, data, and specialty marine cable 
systems on shipboard systems. These recommendations include the present 
day technologies, engineering methods, and engineering practices. We 
propose to replace references to IEEE 45-2002 in Sec. Sec.  111.05-7, 
111.60-5, 111.60-11, 111.60-13, and 111.106-19 with IEEE 45.8-2016. The 
technical content of IEEE 45.8-2016 is similar to IEEE 45-2002, but 
more detailed.
     IEEE 1202-2006--IEEE Standard for Flame-Propagation 
Testing of Wire and Cable with Corrigendum 1 (21 Nov. 2012), 2006. This 
standard provides a protocol for exposing cable samples to a 
theoretical 20 kilowatt (kW) [(70,000 British thermal units per hour 
(Btu/hr)] flaming ignition source for a 20 minute test duration. The 
test determines the flame propagation tendency of single conductor and 
multi-conductor cables intended for use in cable trays. We currently 
reference the 1991 edition in Sec. Sec.  111.60-6 and 111.107-1(c). We 
propose to reference the more recent 2006 edition in Sec.  111.107-
1(c), but not in Sec.  111.60-6, because we are proposing to delete 
that section on fiber optic cable. In the 2006 edition, the normative 
references have been updated, the temperature at which cables are 
conditioned has been raised from 18 [deg]C to 25 [deg]C, and minor 
refinements to the test procedure have been made.
     IEEE 1580-2010--IEEE Recommended Practice for Marine Cable 
for Use on Shipboard and Fixed or Floating Platforms, 2 Mar. 2011. This 
recommended practice contains the requirements for single or 
multiconductor cables, with or without metal armor or jacket, and rated 
300 V to 35 kilovolts (kV), intended to be installed aboard marine 
vessels, and fixed and floating offshore facilities. The 2001 edition 
is currently referenced in Sec. Sec.  111.60-1, 111.60-2, 111.60-3, and 
111.106-5(a). We propose to reference the more recent 2010 edition only 
in Sec. Sec.  111.60-1 and 111.106-5(a), because we propose to delete 
Sec. Sec.  111.60-2 and 111.60-3 in this proposed rule. The 2010 
edition has been updated to incorporate the latest developments in 
marine cable materials and performance enhancements.
     IEC 60068-2-52:2017--Environmental testing Part 2-52: 
Tests--Test Kb: Salt mist, cyclic (sodium chloride solution), Edition 
3.0, 2017-11. This standard specifies the application of the cyclic 
salt mist test to components or equipment designed to withstand a salt-
laden atmosphere as salt can degrade the performance of parts 
manufactured using metallic or non-metallic materials. The second 
edition is referenced in Sec.  110.15-1. We propose to incorporate the 
third edition. In this more recent edition the standard has been 
updated to ensure consistency with International Organization for 
Standardization (ISO) 9227--Corrosion tests in artificial atmospheres--
Salt spray tests.
     IEC 60079-0--Electrical apparatus for Explosive Gas 
Atmospheres--Part 0: General Requirements, Edition 3.1, 2000. This part 
of the IEC 60079 series of standards specifies the general requirements

intended for use in explosive gas atmospheres. We currently reference 
the fourth edition (2001) of this standard in Sec. Sec.  111.105-1, 
111.105-3, 111.105-5, 111.105-7, 111.105-9, and 111.105-17 while the 
sixth edition (2007) is referenced in Sec. Sec.  111.106-3(b) and 
111.108-3(b). We propose to replace all references to the fourth and 
sixth editions of this standard with the more recent edition 7.0 (2014) 
in Sec. Sec.  111.105-7, 111.106-3(b), and 111.108-3(b). The updated 
standard reflects advances in technology, including:
    [cir] Addition of material limitations of enclosures of equipment 
and enclosures of Ex components for external mounting;
    [cir] Addition of power factor requirement for evaluating the 
ability of a plug and socket; to remain flameproof during the arc-
quenching period while opening a test circuit; and
    [cir] Addition of marking requirements for Ex component enclosures, 
in addition to the requirements for marking of Ex components given in 
IEC 60079-0.

111.105-17, while the third edition (2007) is referenced in Sec. Sec.  
111.106-3(b) and 111.108-3(b). We propose to delete all references to 
the second and third edition. The more recent edition 4.0 (2015), 
containing minor technical revisions and clarifications, is proposed 
for Sec. Sec.  111.105-7(a), 111.106-3(b), and 111.108-3(b). This will 
ensure consistent, up-to-date standards for electrical installations on 
all vessel and facility types but will not result in a substantive 
change to the current requirements.
     IEC 60079-6:2015--Explosive atmospheres--Part 6: Equipment

manufacture of electric power, control and instrumentation cables with 
copper conductors intended for fixed electrical systems at voltages up 
to and including 18/30(36) kV on board ships and offshore (mobile and 
fixed) units. We currently reference Edition 3.0 (2008) of this 
standard in Sec.  111.106-5(a). We propose to reference the more recent 
edition, 4.0 (2014), of this standard in Sec.  111.106-5(a) to ensure 
the latest industry practices based on changes in technology are 
addressed. The Coast Guard is proposing to amend subpart 111.60 to 
align with recognized classification society rules and industry 
practice. In support of this effort, this proposed rule would include 
IEC 60092-350:2014 in Sec.  111.60-1(a) concerning construction and 
testing of cable. The 4.0 edition includes the following technical 
changes as compared to the previous edition:
    [cir] The standard includes a reference to IEC 60092-360 for both 
the insulating and sheathing compounds;
    [cir] The standard includes partial discharge tests, which were 
transferred from IEC 60092-354 to align them with IEC 60092-353;
    [cir] The IEC transferred the requirements for oil and drilling-
fluid resistance (former Annexes F and G) to IEC 60092-360;
    [cir] The standard contains improved requirements for cold bending 
and shocks; and
    [cir] The document reflects the changes of material types that were 
introduced during development of IEC 60092-353 and IEC 60092-360.
     IEC 60092-352:2005--Electrical installations in ships--
Part 352: Choice and Installation of electrical cables, Third Edition, 
2005-09. This part of the IEC 60092 series of standards provides the 
basic requirements for the choice and installation of cables intended 
for fixed electrical systems on board ships at voltages up to and 
including 15 kV. We currently reference the second edition (1997) of 
this standard in Sec. Sec.  111.60-3, 111.60-5 and 111.81-1. Because of 
proposed revisions to subpart 111.60, we propose to reference the more 
recent third edition (2005) of this standard in Sec.  111.60-1 and 
111.60-5. Additionally, IEC 60092-352:2005 would replace the previous 
1997 edition referenced in Sec.  111.81-1. The 2005 edition has several 
minor updates including changes to:
    [cir] Sizes of earth continuity conductors and equipment earthing 
connections;
    [cir] Bending radii for cables rated at 3,6/6,0 (7,2) kV and above;
    [cir] Current carrying capacities in amperes at core temperatures 
of 70 [deg]C and 90 [deg]C; and
    [cir] Tabulated current carrying capacities--defined installations.
    To ensure we address the latest technologies and industry 
practices, we are proposing to incorporate the more recent edition of 
this standard.
     IEC 60092-353:2016--Electrical installations in ships--
Part 353: Power cables for rated voltages 1 kV and 3 kV, Edition 4.0, 
2016-09. This part of the IEC 60092 series of standards provides 
manufacturing requirements and characteristics of such cables directly 
or indirectly bearing on safety and specifies test methods for checking 
conformity with those requirements. We currently reference the second 
edition (1995) of this standard in Sec. Sec.  111.60-1, 111.60-3, and 
111.60-5 while the third edition (2011) is referenced in Sec.  111.106-
5(a). We propose to reference the more recent edition 4.0 (2016) only 
in Sec. Sec.  111.60-1(a) and 111.106-5(a), but not Sec.  111.60-3 
because we propose to revise subpart 111.60 regarding cable 
construction. The 2016 edition of this standard includes updates for 
advancements in insulation and sheathing materials, construction 
methods, and test methods. Its incorporation ensures consistent, up-to-
date standards for electrical cable installations.
     IEC 60092-354:2014--Electrical installations in ships--
Part 354: Single- and three-core power cables with extruded solid 
insulation for rated voltages 6 kV (Um=7.2 kV) up to 30 kV (Um=36 kV), 
Edition 3.0, 2014-08. This part of the IEC 60092 series of standards 
provides manufacturing requirements and characteristics of such cables 
directly or in directly bearing on safety and specifies test methods 
for checking conformity with those requirements. We propose to 
reference this standard in Sec.  111.60-1(a). This will align Coast 
Guard requirements with those of recognized classification society 
rules and industry practice.
     IEC 60092-360:2014--Electrical installations in ships--
Part 360: Insulating and sheathing materials for shipboard and offshore 
units, power, control, instrumentation and telecommunication cables, 
Edition 1.0, 2014-04. This part of the IEC 60092 series of standards 
specifies the requirements for electrical, mechanical and particular 
characteristics of insulating and sheathing materials intended for use 
in shipboard and fixed and mobile offshore unit power, control, 
instrumentation, and telecommunication cables. We propose to reference 
this standard in Sec.  111.60-1(a). This will align Coast Guard 
requirements with those of recognized classification society rules and 
industry practice.

     IEC 60092-376:2017--Electrical installations in ships--
Part 376: Cables for control and instrumentation circuits 150/250 V 
(300 V), Third Edition, 2017-05. This part of the IEC 60092 series of 
standards provides manufacturing requirements and characteristics of 
such cables directly or in directly bearing on safety and specifies 
test methods for checking conformity with those requirements. We 
propose to reference this standard in Sec.  111.60-1(a). This will 
align Coast Guard requirements with those of recognized classification 
society rules and industry practice.
     IEC 60092-401:1980--Electrical installations in ships--
Part 401: Installation and test of completed Installation, Third 
Edition with Amendment 1 (1987-02) and Amendment 2 (1995-04). We 
currently reference the 1980 edition in Sec. Sec.  111.05-9 and 111.81-
1(d). This proposed rule would make formatting changes to the 
standard's title for consistency with the titles of all other 
referenced IEC standards, but does not alter the edition incorporated 
by reference.
     IEC 60092-502:1999--Electrical installations in ships--
Part 502: Tankers--Special features, Fifth Edition, 1999-02. This part 
of the IEC 60092 series of standards deals with the electrical 
installations in tankers carrying liquids which are flammable, either 
inherently, or due to their reaction with other substances, or 
flammable liquefied gases. The standard details the zonal concept for 
hazardous area classification. We currently reference the 1992 edition 
in Sec. Sec.  111.81-1, 111.105-31, 111.106-3(b), 111.106-5(c), 
111.106-15(a), and 111.108-3(b). We propose to remove reference to this 
standard in Sec.  111.105-31 and add it into Sec. Sec.  111.105-1, 
111.105-3(b), 111.105-7(a), 111.105-11(b), 111.105-17(b), 111.105-
50(c). This proposed rule would make formatting changes to the 
standard's title for consistency with the titles of all other 
referenced IEC standards, but does not alter the edition incorporated 
by reference. Additionally, we propose to allow classification of 
hazardous locations based on this document. That proposal is described 
in more detail in section VI.D later in this discussion of the proposed 
rule.
     IEC 60092-503:2007--Electrical installations in ships--
Part 503: Special features--A.C. supply systems with voltages in the 
range of above 1kV up to and including 15 kV, Second edition, 2007-06. 
This part of the IEC 60092 series of standards covers the design and 
installation requirements for AC supply systems with voltages in the 
range of above 1 kV. We currently reference the first edition (1975) of 
this standard in Sec.  111.30-5(a). We propose to reference the more 
recent second edition (2007) of this standard. The second edition 
covers a greater range of voltages and has updated technical 
requirements.
     IEC 60331-11:2009--Tests for electric cables under fire 
conditions--Circuit integrity--Part 11: Apparatus--Fire alone at a 
flame temperature of at least 750 [deg]C, Edition 1.1, 2009-07. This 
part of IEC 60331 specifies the test apparatus to be used for testing 
cables required to maintain circuit integrity when subject to fire. We 
currently reference the first edition (1999) of this standard in Sec.  
113.30-25. We propose to reference the more recent 1.1 edition (2009) 
of this standard, which includes minor technical updating, to ensure 
the latest industry practices based on changes in technology are 
addressed.
     IEC 60331-21:1999--Tests for electric cables under fire 
conditions--Circuit integrity--Part 21: Procedures and requirements--
Cables of rated voltage up to and including 0.6/1.0 kV, First Edition, 
1999-04. We currently reference this 1999 edition in Sec.  113.30-
25(j). This proposed rule would make formatting changes to the 
standard's title for consistency with the titles of all other 
referenced IEC standards, but does not alter the edition incorporated 
by reference.
     IEC 60332-1-1:2015--Tests on electric and optical fibre 
cables under fire conditions--Part 1-1: Test for vertical flame 
propagation for a single insulated wire or cable--Apparatus, First 
Edition with Amendment 1 (2015-07), 2004-07. This part of IEC 60332 
specifies the apparatus for testing the resistance to vertical flame 
propagation for a single vertical electrical insulated conductor or 
cable, or optical cable, under fire conditions. This standard, along 
with IEC 60332-1-2:2015, supersedes IEC 60332-1:1993 currently 
referenced in Sec.  111.30-19(b). We propose to replace the superseded 
1993 standard in 111.30-19(b) with IEC 60332-1-1:2015 and IEC 60332-1-
2:2015. IEC 60332-1-1:2015 covers the test apparatus and IEC 60332-1-
2:2015 covers the testing procedure. The technical content is similar 
to the 1993 edition, but has been updated with greater specificity 
regarding the ignition source, test sample size, and positioning of the 
test flame.
     IEC 60332-1-2:2015--Tests on electric and optical fibre 
cables under fire conditions--Part 1-2: Test for vertical flame 
propagation for a single insulated wire or cable--Procedure for 1kW 
pre-mixed flame, First Edition with Amendment 1, 2015-07. This part of 
IEC 60332 specifies the procedure for testing the resistance to 
vertical flame propagation for a single vertical electrical insulated 
conductor or cable, or optical cable, under fire conditions. This 
standard, along with IEC 60332-1-1:2015, supersedes IEC 60332-1:1993, 
which we currently reference in Sec.  111.30-19(b). We propose to 
reference IEC 60332-1-2:2015, regarding the testing procedure, in Sec.  
111.30-19(b). The technical content is similar to the 1993 edition, but 
the updates in the standard provide greater specificity regarding the 
ignition source, test sample size, and positioning of the test flame.
     IEC 60332-3-21:2018--Tests on electric and optical fibre 
cables under fire conditions--Part 3-21: Test for vertical flame spread 
of vertically-mounted bunched wires or cables--Category A F/R, Edition 
2.0, 2018-07. This part of IEC 60332-3 specifies the procedure for 
testing the resistance to vertical flame propagation for vertically-
mounted bunched wires or cables, under defined conditions. Edition 2.0 
(2018-7) retains and updates pre-existing categories of tests, adds a 
new category (category D) for testing at very low non-metallic volumes, 
and emphasizes that it applies to optical fibre cables as well as 
metallic conductor cables. We propose this standard for incorporation 
in Sec. Sec.  111.60-1(b) and 111.107-1(c).
     IEC 60332-3-22:2018--Tests on electric cables under fire 
conditions--Part 3-22: Test for vertical flame spread of vertically-
mounted bunched wires or cables--Category A, Edition 2.0, 2018-07. This 
part of IEC 60332-3 specifies methods of test for assessment of 
vertical flame spread of vertically-mounted bunched wires or cables, 
electrical or optical, under defined conditions. We propose to remove 
references to the superseded first edition (2000) of this standard in 
Sec. Sec.  111.60-1, 111.60-2, 111.60-6, and 111.107-1. Because Sec.  
111.60-6 does not need to reference this test, we propose to delete 
Sec.  111.60-2 and to reference the more recent edition 2.0 (2018) of 
this standard only in Sec. Sec.  111.60-1 and 111.107-1(c). This more 
recent edition retains and updates the pre-existing categories of 
tests, adds a new category (category D) for testing at very low non-
metallic volumes, and emphasizes that it applies to optical fibre 
cables as well as metallic conductor cables.
     IEC 60529:2013--Degrees of protection provided by 
enclosures (IP Code), Edition 2.2, 2013-08. This standard describes a 
system for classifying the degrees of protection provided by the 
enclosures of electrical equipment as well as the requirements

[[Page 21452]]

for these degrees of protection and tests to verify the requirements. 
We currently reference Edition 2.1 (2001) of this standard in 
Sec. Sec.  110.15-1, 111.01-9, 113.10-7, 113.20-3, 113.25-11, 113.30-
25, 113.37-10, 113.40-10, and 113.50-5. In these sections, we propose 
to reference the more recent edition 2.2 (2013) of this standard. 
Edition 2.2 (2013) is a minor technical update to the standard.
     IEC 60533:2015--Electrical and electronic installations in 
ships--Electromagnetic compatibility--Ships with a metallic hull, 
Edition 3.0, 2015-08. This standard specifies minimum requirements for 
emission, immunity, and performance criteria regarding electromagnetic 
compatibility (EMC) of electrical and electronic equipment for ships 
with metallic hull. We currently reference the second edition (1999) of 
this standard in Sec.  113.05-7(a). We propose to reference the more 
recent edition 3.0 (2015) of this standard. This edition includes the 
following technical changes with respect to the previous edition:
    [cir] The scope and title have been modified to limit the 
application of the standard to installations in ships with metallic 
hulls only;
    [cir] The normative references have been updated;
    [cir] Further explanation for in-situ testing has been given in 
section 5.1;
    [cir] Cable routing requirements in Annex B have been amended; and
    [cir] A new Annex C EMC test report has been added.
     IEC 60947-2:2019--Low-voltage switchgear and controlgear--
Part 2: Circuit-breakers, Edition 5.1, 2019-07. This standard provides 
circuit-breaker construction and testing requirements. We currently 
reference the third edition (2003) of this standard in Sec.  111.54-
1(b). We propose to reference the more recent edition 5.1 (2019) of 
this standard. The 2019 edition of this standard contains numerous 
technical updates addressing technical advancements, including circuit-
breaker testing, instantaneous trip circuit-breakers, and 
electromagnetic compatibility.
     IEC 61363-1:1998--Electrical installations of ships and 
mobile and fixed offshore units--Part 1: Procedures for calculating 
short-circuit currents in three-phase a.c., first edition, 1998-02. 
This proposed rule would make formatting changes to the standard's 
title for consistency with the titles of all other referenced IEC 
standards, but does not alter the edition currently incorporated by 
reference. We currently reference this 1998 edition in Sec.  111.52-5. 
This proposed rule would move the standard to the new Sec.  111.51-4(b) 
because we propose combining the requirements of subparts 111.51 and 
111.52 into a single subpart 111.51 (Calculation of Short-Circuit 
Currents and Coordination of Overcurrent Protective Devices).
     IEC 61439-6: 2012--Low-voltage switchgear and controlgear 
assemblies--Part 6: Busbar trunking systems (busways), Edition 1.0, 
2012-05. This standard states busbar service conditions, construction 
requirements, technical characteristics and verification requirements 
for low voltage busbar trunking systems. We propose to add it to the 
revised Sec.  111.59-1 concerning general requirements for busways.
     IEC 61660-1:1997--Short-circuit currents in d.c. auxiliary 
installations in power plants and substations--Part 1: Calculation of 
short-circuit currents, First Edition, 1997-06. This standard describes 
a method for calculating short-circuit currents in DC auxiliary systems 
in power plants and substations. We propose to include it in the 
revised Sec.  111.51-4(b) as an alternative for short-circuit analysis.
     IEC 61892-7:2019--Mobile and fixed offshore units--
Electrical installations--Part 7: Hazardous areas, Edition 4.0, 2019-
04. This standard contains provisions for hazardous areas 
classification and choice of electrical installation in hazardous areas 
in mobile and fixed offshore units, including pipelines, pumping or 
``pigging'' stations, compressor stations and exposed location single 
buoy moorings, used in the offshore petroleum industry for drilling, 
processing, and for storage purposes. We currently reference Edition 
2.0 (2007) of this standard in Sec.  111.108-3(b). We propose to update 
the reference in Sec.  111.108-3(b) to the more recent edition 4.0 
(2019) and to insert new references to this standard in Sec. Sec.  
111.105-1, 111.105-3(b), 111.105-7, and 111.105-17(b). The standard has 
been completely rewritten. The Explosion Protection Level concept has 
been introduced as an alternative risk-based classification method and 
the requirements for installations in hazardous conditions reference 
IEC 60079-14 and other relevant standards, as appropriate. The 
incorporation of this standard into subpart 111.105 will provide an 
alternate standard for classifications for hazardous locations.
     IEC 62271-100:2017--High-voltage switchgear and 
controlgear--Part 100: Alternating-current circuit-breakers, Edition 
2.2, 2017-06. This standard provides construction and testing 
requirements for circuit-breakers having voltages above 1000 V. We 
currently reference Edition 1.1 (2003) of this standard in Sec.  
111.54-1(c). We propose to reference the more recent edition 2.2 (2017) 
of this standard. There have been numerous technical updates to address 
technical advancements in switchgear. To ensure we address the latest 
technologies and industry practices, we are proposing to incorporate 
the more recent edition of this standard.
     IEC-TR 60092-370:2009--Technical Report--Electrical 
installations in ships--Part 370: Guidance on the selection of cables 
for telecommunication and data transfer including radio-frequency 
cables, Edition 1.0, 2009-07. This technical report gives guidance and 
basic recommendations for the selection and installation of shipboard 
and offshore unit cables intended for electrical systems used in both 
essential and non-essential analogue or digital signal communication, 
transmission, and control networks, including types suitable for high-
frequency signals (i.e., signals with a frequency of more than 10\5\ 
Hertz). We propose to reference this new standard in Sec.  111.60-1. 
This will align our requirements with those of recognized 
classification society rules and industry practice.
     IEC/IEEE 80005-1:2019--Utility connections in port--Part 
1: High voltage shore connection (HVSC) systems--General requirements, 
Edition 2.0, 2019-03. This standard describes the design, installation, 
and testing of HVSC systems, on board the ship and on shore, to supply 
the ship with electrical power from shore. Ships may be required by 
state or local laws to connect to high voltage shore power (over 1000 
V) rather than running their onboard generators. We propose in Sec.  
111.83-7 that these ships meet the requirements of this standard.
     International Convention for the Safety of Life at Sea 
(SOLAS), Consolidated Text of the International Convention for the 
Safety of Life at Sea, 1974, and its Protocol of 1988: Article, Annexes 
and Certificates. (Incorporating all amendments in effect from 1 July 
2014), 2014. SOLAS provides requirements for vessel construction, 
arrangement, and management on international voyages. We reference 
SOLAS 2001 requirements in Sec. Sec.  111.99-5, 112.15-1, and 113.25-6 
and propose to incorporate the latest 2014 edition of SOLAS. While the 
applicable sections of SOLAS referenced in these requirements have not 
changed, for completeness we are incorporating the latest SOLAS 
amendments because industry is likely to use the more recent edition.
     International Maritime Organization Resolution 
A.1023(26)--

[[Page 21453]]

Code for the Construction and Equipment of Mobile Offshore Drilling 
Units, 2009. We propose nonsubstantive formatting change to the listing 
of this resolution in Sec.  110-10-1(b). Chapter 6 of this resolution 
is referenced in Sec.  111.108-3(b). The resolution provides 
requirements for machinery and electrical installations in hazardous 
areas of mobile offshore drilling units.
     International Society of Automation (ISA) RP 12.6--Wiring 
Practices for Hazardous (Classified) Locations Instrumentation Part I: 
Intrinsic Safety, 1995. We are proposing to delete this standard from 
reference in Sec.  111.105-11. It has been withdrawn by ISA, is no 
longer supported by ISA, and is not available at www.isa.org. Instead, 
we propose to reference NFPA 70 and IEC 60092-502:1999 for the 
intrinsically safe system requirements in Sec.  111.105-11.
     ISO 25861--Ships and marine technology--Navigation--
Daylight signaling lamps, first edition, Dec, 1, 2007. We are proposing 
to reference this standard in Sec.  111.75-18 regarding daylight 
signaling lamps. This standard provides performance requirements for 
daylight signaling lamps pursuant to chapter V of SOLAS, 1974, as 
amended, and chapter 8 of the International Code for Safety for High-
Speed Craft. The performance standards for daylight signaling lamps 
currently in Sec.  111.75-18 are based on the international 
requirements in place in 1996. These requirements have been superseded 
by the requirements contained in ISO 25861.
     Lloyd's Register Type Approval System-Test Specification 
Number 1, March 2019. This specification details performance and 
environmental testing required for products used in marine 
applications. We currently reference the 2002 edition of this standard 
in Sec.  113.05-7(a). We propose to reference the more recent 2019 
edition. It has been updated several times to keep pace with changes in 
environmental testing.

Standards Publication ICS 2-2000 (R2005)--Industrial Control and 
Systems Controllers, Contactors, and Overload Relays, Rated 600 Volts, 
2000. This edition is referenced in Sec.  111.70-3. NEMA reaffirmed the 
edition without change in 2005. We propose to reference the reaffirmed 
date in the standard's title, which would result in no substantive 
changes.
     NEMA Standards Publication ICS 2.3-1995--Instructions for 
the Handling, Installation, Operation, and Maintenance of Motor Control 
Centers Rated not More Than 600 Volts, 1995 (R2008). This edition is 
referenced in Sec.  111.70-3. NEMA reaffirmed the edition without 
change in 2008. We propose to reference the reaffirmed date in the 
standard's title, which would result in no substantive changes.
     NEMA Standards Publication No. ICS 2.4-2003 (R2102)--NEMA 
and IEC Devices for Motor Service--a Guide for Understanding the 
Differences, 2003. This edition is referenced in Sec.  111.70-3. NEMA 
reaffirmed the edition without change in 2012. We propose to reference 
the reaffirmed date in the standard's title, which would result in no 
substantive changes.
     NEMA Standards Publication No. ANSI/NEMA 250-2018--
Enclosures for Electrical Equipment (1000 Volts Maximum), Edition 14, 
2018. This standard covers classification of enclosures for electrical 
equipment as well as the requirements for these enclosures and tests to 
demonstrate conformance with the requirements. We currently reference 
the 1997 edition of this standard in Sec. Sec.  110.15-1, 111.01-9, 
113.10-7, 113.20-3, 113.25-11(a), 113.30-25(e), 113.37-10(b), 113.40-
10(b), and 113.50-5(g). We propose to reference the more recent 2014 
edition in these sections. The 2014 edition added several new enclosure 
types as well as several minor construction details.
     NEMA Standards Publication No. WC-3-1992--Rubber Insulated 
Wire and Cable for the Transmission and Distribution of Electrical 
Energy, Revision 1, Feb. 1994. This is one of many options listed as a 
standard for allowable current-carrying capacity. We propose to delete 
it from Sec.  111.60-13(c) because NEMA rescinded the standard.
     ANSI/NEMA WC-70 ICEA S-95-658--Power Cables Rated 2000 V 
or Less for the Distribution of Electrical Energy, Feb. 23, 2009. This 
standard applies to materials, constructions, and testing of 2000 V and 
less thermoplastic, cross-linked polyethylene, and cross-linked rubber 
insulated wires and cables which are used for the transmission and 
distribution of electrical energy for normal conditions of installation 
and service, either indoors, outdoors, aerial, underground, or 
submarine. We currently reference the 1999 edition of this standard, 
NEMA WC-70ICEA S-95-658, in Sec.  111.60. We propose to reference the 
more recent 2009 edition with the updated naming convention. The 2009 
standard contains updates based on advancements in technology including 
new cable jacket types and updated testing methods.
     National Fire Protection Association (NFPA) 70--National 
Electrical Code, 2017 Edition. This code is referenced in many sections 
of subchapter J and is the basis for electrical regulations worldwide. 
Currently, both the 2002 and 2014 editions of the code are incorporated 
by reference in Sec. Sec.  111.05-33, 111.20-15, 111.50-3, 111.50-7(a), 
111.50-9, 111.53-1(a), 111.54-1(a), 111.55-1(a), 111.59-1, 111.60-7, 
111.60-13, 111.60-23, 111.81-1(d), 111.105-1, 111.105-3, 111.105-7(a), 
111.105-11, 111.105-17(b), 111.106-3(b), 111.106-5(c), 111.107-1(b) and 
111.108-3(b)(1) and (2). We propose to reference the 2017 edition in 
all the aforementioned sections where the NFPA 70 code is referenced. 
We also propose to include Sec.  110.15-1 in the list of sections 
referencing NFPA 70 because NFPA 70 is currently used in the definition 
of ``Special Division 1''. Substantive changes to the NFPA 70 articles 
between the previous editions include the following:
    [cir] Article 240--This article on overcurrent protection raised 
the threshold for high voltage overcurrent protection from 600 V to 
1000 V. Additionally, it addresses arc energy reduction of fuses rated 
at 1200A or higher.
    [cir] Article 250.119--Section 250.119 details the identification 
requirements for equipment grounding conductors. The 2017 and 2002 
editions are similar, but the 2017 edition contains greater specificity 
for specific installations and prohibits other cables to be covered in 
manner that could confuse them with equipment grounding conductors.
    [cir] Article 250.122--Section 250.122 details requirements for the 
size of equipment grounding conductors. The content in the two editions 
is similar, but the 2017 edition adds requirements for multi-conductor 
cable, consideration of instantaneous-trip circuit breakers or motor 
short-circuit protectors, and greater specificity for flexible cord and 
fixture wire.
    [cir] Article 250--This article on grounding conductors has been 
updated based on changes in technology and has added requirements for 
conductors in raceways and multiconductor cable.
    [cir] Article 314--This article on outlet or junction boxes has 
several minor updates based on changes in technology or industry 
practices.
    [cir] Article 368--This article on busways was reformatted and the 
threshold for high voltage busways was raised from 600 V to 1000 V. 
Additionally it provides more detailed wiring requirements.
    [cir] Article 400--This article on flexible cords and cable 
provides several additional types of flexible cords as well as 
conductor sizes, but the allowable

[[Page 21454]]

ampacities for the existing types of flexible cords and cables have not 
changed. Additionally, it requires that the maximum operating 
temperature be added to the required markings.
    [cir] Article 404--It has been clarified that this article on 
switches in <1000 V systems and several additional switch types have 
been added.
    [cir] Article 430--This article on motors now raises the threshold 
for motors requiring additional protective measures from 600 V to 1000 
V. Part X has been added to provide greater detail on adjustable-speed 
drive systems. Additionally a variety of minor technical updates made 
as well as referencing the latest standards.
    [cir] Article 450--This article on transformers raised the 
transformer threshold for high voltage transformers from 600 V to 1000 
V. Additionally minor editorial changes were made. For example, in 
several sections the word ``sufficient'' was replaced with ``not less 
than'' to ensure the intent was clear.
    [cir] Article 504--Sections 504.10, 504.30, 504.50 and 504.60 on 
intrinsically safe system design are proposed to be added in Sec.  
111.105-11 because ISA RP 12.6 has been withdrawn by ISA. The 
requirements are similar and NFPA is the authoritative standard for 
electrical engineering design.
     NFPA 77--Recommended Practice on Static Electricity, 2019 
Edition. This recommended practice applies to the identification, 
assessment, and control of static electricity for purposes of 
preventing fires and explosions. We currently reference the 2000 
edition of this standard in Sec.  111.105-27(b). We propose to 
reference the more recent, 2019 edition, which has been completely 
reorganized but the technical content is very similar. However, the 
2019 editions contains changes regarding the characterization of 
combustible dust.
     NFPA 99--Health Care Facilities Code, 2018. This code 
provides information on health care facilities related to medical gas 
and vacuum systems, electrical systems, electrical equipment, and gas 
equipment. We currently reference the 2005 edition of this standard in 
Sec.  111.105-37. We propose to reference the more recent 2018 edition. 
The 2018 standard contains extensive updates and is the authoritative 
reference for flammable anesthetics.
     NFPA 496--Standard for Purged and Pressurized Enclosures 
for Electrical Equipment, 2017 Edition. This standard applies to 
purging and pressurizing for electrical equipment in hazardous 
locations, electrical equipment containing sources of flammable vapors, 
control rooms or buildings in hazardous locations, and analyzer rooms 
containing sources of flammable vapors or gases and located in 
hazardous locations. We currently reference the 2003 edition of this 
standard in Sec.  111.105-7, the 2008 edition is currently referenced 
in Sec.  111.106-3(c), and the 2013 edition is currently referenced in 
Sec.  111.108-3(d). We propose to update the reference to the more 
recent 2017 edition in Sec. Sec.  111.105-7, 111.106-3(c), and 111.108-
3(d). The standard was revised to ensure correlation with the 2011 
edition of NFPA 70. The definitions of ``energized'' and ``identified'' 
are extracted from NFPA 70. Equipment is required to be identified for 
use in a classified area, and the requirements for determining the 
suitability of identified equipment have been clarified. NFPA 496 
clarified the definitions of Type X, Type Y, and Type Z pressurizing to 
more clearly define their usage. NFPA 496 has been an industry standard 
for purged and pressurized enclosures since 1971. Further, the newer 
edition no longer includes unspecific language such as ``near'', 
``close to'', and ``significant portion.'' Such terms cannot be 
quantified in the design or evaluation of an installation designed to 
the standard.
     Naval Sea Systems Command (NAVSEA) DDS 300-2--A.C. Fault 
Current Calculations, 1988. We propose to remove this standard from 
Subchapter J because it is no longer supported or available. This is 
one of four options for fault calculations in Sec.  111.52-5. We 
propose to reorganize the requirements for short-circuit calculations 
for systems 1500 kilowatts or above in Sec.  111.52-5 into new Sec.  
111.51-4. The other three options would be included in the new Sec.  
111.51-4.
     MIL-HDBK-299(SH), 1991--Military Handbook Cable Comparison 
Handbook Data Pertaining to Electric Shipboard Cable Notice 1-1991. 
This document provides basic information on, and listings of, shipboard 
cables and also provides guidance for their design, handling, 
installation, and maintenance. This current edition is referenced in 
Sec.  111.60-3 regarding cable applications. We propose to delete this 
standard because we are also proposing to delete Sec.  111.60-3, which 
we discuss in section VI.C of this preamble as being unnecessarily 
prescriptive.
     UL 44--Standard for Safety Thermoset-Insulated Wire and 
Cable, 2018. This standard specifies the requirements for single-
conductor and multiple-conductor thermoset-insulated wires and cables 
rated 600 V, 1000 V, 2000 V, and 5000 V. We currently reference the 
fifteenth edition (1999) of this standard in Sec.  111.60-11(c). We 
propose to reference the nineteenth edition (2018). The standard has 
been completely updated based on changes in technology and now 
addresses wires and cables up to 5000 V. The 2002 edition only went to 
2000 V. Additionally, new wire types and maximum voltage ratings are 
addressed
     UL 50--Standard for Safety Enclosures for Electrical 
Equipment, 2013. This standard covers the non-environmental 
construction and performance requirements for enclosures to protect 
personnel against incidental contact with the enclosed equipment. We 
currently reference the eleventh edition (1995) of this standard in 
Sec.  111.81-1(d). We propose to reference the more recent thirteenth 
edition (2013). The updated standard addresses the following additional 
items:
    [cir] Addition of environmental Type ratings 3X, 3RX, and 3SX;

    [cir] Clarification of types of cast metal suitable for use as an 
enclosure;
    [cir] Equipment door opening 90 degrees from the closed position;
    [cir] Certification Requirement Decision for nonmetallic-sheathed 
cable clamps; and
    [cir] Revision to requirement of cover and flange overlap for 
cabinets used as panelboards.
     UL 62--Standard for Safety Flexible Cords and Cables, 
2018. This standard specifies the requirements for flexible cords, 
elevator cables, electric vehicle cables, and hoistway cables rated 600 
V maximum. We currently reference the sixteenth edition (1997) of this 
standard in Sec.  111.60-13(a). We propose to reference the more recent 
twentieth edition (2018). This standard has been updated based on 
advancements in technology to address new cable types, jacket types, 
and testing techniques. To ensure we address the latest technologies 
and industry practices, we are proposing to incorporate the more recent 
edition of this standard.
     UL 83--Standard for Safety Thermoplastic-Insulated Wires 
and Cables, 2017. This Standard specifies the requirements for 600 V, 
single-conductor, thermoplastic-insulated wires and cables. We 
currently reference the twelfth edition (1998) of this standard in

(2017). The standard has been completely

[[Page 21455]]

updated based on changes in technology. For example, it now addresses 
many new types of wire, wire sizes, and updated testing requirements.
     UL 484--Standard for Safety Room Air Conditioners, 2014. 
This standard provides requirements for room air conditioners rated not 
more than 600 V AC. We currently reference the seventh edition (1993) 
of this standard in Sec.  111.87-3(a). We propose to reference the more 
recent, ninth edition (2014). The standard has been updated to account 
for current technology and environmental testing. In addition, sections 
dealing with smart air conditioners and air conditioners using 
flammable refrigerants have been added. To ensure we address the latest 
technologies and industry practices, we are proposing to incorporate 
the more recent edition of this standard.
     UL 489--Standard for Safety Molded-Case Circuit Breakers, 
Molded-Case Switches, and Circuit-Breaker Enclosures, 2016. This 
standard provides requirements for molded-case circuit breakers, 
circuit breaker and ground-fault circuit-interrupters, fused circuit 
breakers, high-fault protectors, and high-fault modules. These circuit 
breakers are specifically intended to provide service entrance, feeder, 
and branch circuit protection. We currently reference the ninth edition 
(1996) of this standard in Sec. Sec.  111.01-15(c) and 111.54-1(b). We 
propose to reference the thirteenth edition (2016). There have been 
numerous technical updates to the standard. The scope has been 
increased to address component testing, programmable components, 
electronic overprotection, and electromagnetic compatibility. To ensure 
we address the latest technologies and industry practices, we are 
proposing to incorporate the more recent edition of this standard.
     UL 514A--Standard for Safety Metallic Outlet Boxes, 2013. 
This standard provides requirements for metallic outlet boxes including 
those intended for marine applications. We currently reference the 
ninth edition (1996) of this standard in Sec.  111.81-1(d). We propose 
to reference the more recent, eleventh edition (2013). UL 514A has been 
revised and updated to account for advancements outlet box 
construction. It has been an industry standard for metallic outlet 
boxes since 1928.
     UL 514B--Standard for Safety Conduit, Tubing, and Cable 
Fittings, 2012. This standard provides requirements for fittings for 
use with cable and conduit. We currently reference the fourth edition

types.
     UL 823--Electric Heaters for Use in Hazardous (Classified) 
Locations, 2006. This standard provides requirements for electric 
heaters suitable for use in hazardous (classified) locations. We 
currently reference the ninth edition (2006) of this standard in 
Sec. Sec.  111.106-3(b) and 111.108-3(b). We propose to reference the 
ninth edition (2006) in Sec.  111.105-7(a), as well. This ensures that 
standards are consistent for electrical installations on all vessel and 
facility types.
     UL 844--Standard for Safety: Luminaires for Use in 
Hazardous (Classified) Locations, 2012. This standard provides 
requirements for fixed and portable luminaires for installation and use 
in hazardous (classified) locations. We currently reference the twelfth 
edition (2006) of this standard in Sec.  111.106-3(b) and the 
thirteenth edition (2012) is referenced in Sec.  111.108-3(b). We 
propose to reference the more recent, thirteenth edition (2012), in 
Sec. Sec.  111.105-7(a), 111.106-3(b), and 111.108-3(b). This latest 
edition includes the following minor technical revisions:
    [cir] Revisions for test paint for spray booth luminaires;
    [cir] Revisions for temperature tests at elevated ambient 
temperatures; and
    [cir] Clarification of required number of as-received samples of 
polymeric enclosure materials.
     UL 913--Standard for Safety: Intrinsically Safe Apparatus 
and Associated Apparatus for Use in Class I, II, and III, Division 1, 
Hazardous Locations, Eighth Edition, 2013. This standard provides 
requirements for apparatus or parts of apparatus intended for 
installation in hazardous locations. We currently reference the sixth 
edition (2002) of this standard in Sec.  111.105-7(a) and the seventh 
edition (2006) is referenced in Sec. Sec.  111.106-3(b) and 111.108-
3(b). We propose to reference the more recent eighth edition (2013) in 
Sec. Sec.  111.105-7(a), 111.106-3(b), and 111.108-3(b). This latest

[[Page 21456]]

shielded and nonshielded medium-voltage power cables. We currently 
reference the third edition (2001) of this standard in Sec.  111.60-
1(a). We propose to reference the more recent fourth edition (2006). 
The fourth edition contains revised supplemental jacket thicknesses. 
Because supplemental jackets are only required for cables intended to 
be buried in the ground, this revision has no substantive impact on UL 
1072 cables intended for use on vessels.
     UL 1104--Standard for Marine Navigation Lights, Second 
Edition, 1998. This standard provides construction and testing 
requirements for navigation lights. This standard is referenced in 
Sec.  111.75-17(f). The only changes proposed to this standard are to 
align the naming convention in the regulatory text with that of other 
UL standards and to specifically cite paragraph (f).
     UL 1203--Standard for Safety: Explosion-Proof and Dust-
Ignition Proof Electrical Equipment for Use in Hazardous (Classified) 
Locations, 2013. This standard covers explosion-proof and dust-
ignition-proof electrical equipment for installation and use in 
hazardous locations. We currently reference the third edition (2000) of 
this standard in Sec.  111.105-9 and the fourth edition (2006) in 
Sec. Sec.  111.106-3(b) and 111.108-3(b). We propose to reference the 
more recent fifth edition (2013) in Sec.  111.105-7(a) instead of Sec.  
111.105-9 due to editorial reformatting of Sec. Sec.  111.105-7(a), 
111.106-3(b), and 111.108-3(b). The more recent edition has relatively 
minor technical clarifications with minimal substantive changes.
     UL 1309--Standard for Safety Marine Shipboard Cables, 
2017. This standard provides requirements for distribution (power) 
cables, and control and signal cables, for installation aboard marine 
vessels, fixed and floating offshore petroleum facilities, and Marine 
Offshore Drilling Units (MODUs). We currently reference the first 
edition (1995) of this standard in Sec. Sec.  111.60-1, 111.60-3, and 
111.106-5(a). We propose to reference the more recent, third edition 
(2017) only in Sec. Sec.  111.60-1 and 111.106-5(a), because we are 
proposing to delete Sec.  111.60-3. The standard has received updates 
to its construction, performance, ratings, and markings requirements.
     UL 1581--Standard for Safety Reference Standard for 
Electrical Wires, Cables, and Flexible Cords, 2001. We propose to 
delete references to this standard in Sec. Sec.  111.30-19, 111.60-2, 
and 111.60-6 because the referenced test in this standard, VW-1, has 
been moved to UL 2556.
     UL 1598--Standard for Safety Luminaires, 2018. This 
standard provides requirements for luminaires for use in nonhazardous 
locations that are intended for installation on branch circuits of 600 
V nominal or less. We currently reference the first edition (2000) of 
this standard in Sec.  111.75-20. We propose to reference the more 
recent fourth edition (2018), which has been extensively updated based 
on changes in technology and construction techniques. This edition 
includes added requirements for placement and construction of light-
emitting diode (LED) luminaires as well as LED test methods. The 
standard also includes LED components and subassemblies, and other LED 
requirements.
     UL 1598A--Standard for Safety Supplemental Requirements 
for Luminaires for Installation on Marine Vessels, First Edition (with 
revisions through Apr. 17, 2015), Dec. 4, 2000. The First Edition, 
December 4, 2000, is currently incorporated by reference in Sec.  
111.75-20. We propose to incorporate the First Edition with revisions 
through April 17, 2015 in this section. UL 1598A provides additional 
requirements for luminaires meeting UL 1598 and intended for vessels to 
ensure these luminaires are suitable for marine and shipboard 
environments. The revisions to the First Edition include non-
substantive updates necessary due to changes in to clauses of standards 
referenced within UL 1598A that occurred since publication of the First 
Edition.
     UL 1604--Electrical Equipment for use in Class I and II, 
Division 2 and Class III Hazardous (Classified) Locations, 1994. We 
propose to delete this standard from Sec.  111.108-3(b) because UL 
withdrew it and it is no longer an active standard. This is one of many 
options in Sec.  111.108-3(b) for standards on electrical equipment in 
hazardous locations.
     UL 2021--Standard for Safety Fixed and Location-Dedicated 
Electric Room Heaters, 2015. We propose to reference this standard in 
Sec.  111.87-3(a). This standard provides requirements for electric air 
heaters. It will be an additional standard regulated entities may 
choose for electric air heaters. We have previously accepted it on a 
case-by-case basis as equivalent to the existing standards in Sec.  
111.87-3(a).
     UL 2225--Standard for Safety: Cables and Cable-Fittings 
for use in Hazardous (Classified) Locations, 2013. We currently 
reference the second edition (2005) of this standard in Sec.  111.106-
3(b) and the third edition (2011) of this standard in Sec.  111.108-
3(b). We propose to reference the more recent fourth edition (2013) in 
Sec. Sec.  111.105-7(a), 111.106-3(b), and 111.108-3(b). The latest 
edition includes the addition of Type TC-ER-HL cable for use in Class 
I, Zone 1 as permitted by the 2014 National Electrical Code to the 
scope, editorial revisions, and error corrections sections of the 
standard. The incorporation of this edition into all three sections 
ensures consistent, up-to-date standards for electrical installations 
on all vessel and facility types.
     UL 2556--Wire and Cable Test Methods, 2015. This standard 
describes the apparatus, test methods, and formulas to be used in 
carrying out the tests and calculations required by wire and cable 
standards. The flame retardant test VW-1, formerly of UL 1581, has been 
moved to this standard and is now called FV-2/VW-1. We propose to 
replace the UL 1581 with UL 2556 in Sec.  111.30-19(b).
     UL 60079-18--Standard for Safety Explosive Atmospheres--
Part 18: Equipment Protection by Encapsulation ``m'', 2017. We propose 
this standard as a replacement for the ANSI/ISA 60079-18, which was 
withdrawn. UL 60079-18 is not substantively different than ANSI/ISA 
60079-18. This standard gives the specific requirements for the 
construction, testing and marking of electrical equipment, parts of 
electrical equipment and Ex components with the type of protection 
encapsulation ``m'' intended for use in explosive gas atmospheres or 
explosive dust atmospheres. We propose to reference this standard in 
Sec. Sec.  111.105-7(e), 111.106-3(d), and 111.108-3(e).

B. Generator Prime Movers

    We propose to delete the requirements in Sec. Sec.  111.12-1(b) and 
(c) for each generator prime mover to have an independent overspeed 
device and a loss of lubricating oil pressure to the generator bearing 
oil pressure shutdown. The ABS Steel Vessel Rules, which are already 
incorporated by reference in Sec.  58.01-5, require these same 
safeguards on all but small, generator prime movers. The independent 
overspeed device is required for each engine driving a generator of 220 
kW (295 hp) and above, while the oil pressure shutdown is required for 
generators of 100 kW (135 hp) and above. This sufficiently addresses 
the concerns that Sec.  111.12-1(b) and (c) were intended to address. 
The Coast Guard has required generator prime movers to meet ABS rules 
since 1965. We propose to incorporate the ABS Steel Vessel Rules for 
generator

[[Page 21457]]

prime movers without modification to reduce reliance on government-
unique standards where an existing voluntary standard will suffice, as 
advocated in OMB Circular A-119.

C. Electrical Cable

    We propose to update and amend subpart 111.60 (Wiring Materials and 
Methods) to align it more closely with the standards accepted 
internationally by vessel classification societies and foreign 
administrations. Vessels participating in the Coast Guard's Alternate 
Compliance Program are constructed and operated in accordance with 
classification society rules and are not required to meet all of the 
requirements in subpart 111.60. We are not aware of any casualties as a 
result of this.
    We propose to add several additional cable construction standards 
to Sec.  111.60-1, thus creating a broader list of acceptable 
standards. This has allowed us to propose removing many of the more 
prescriptive cable requirements in Sec. Sec.  111.60-2, 111.60-3, 
111.60-4, and 111.60-6 because of the availability of widely accepted 
additional standards. For example, cable for communication and radio 
frequency applications, and fiber optic cable, are available to meet 
the standards of Sec.  111.60-1 and therefore Sec. Sec.  111.60-2 and 
111.60-6 are no longer necessary.
    We also propose deleting the cable application regulations in Sec.  
111.60-3 as they are unnecessarily prescriptive. Instead, entities 
would consult the current and proposed cable construction standards in 
proposed Sec.  111.60-1 for the application of specific types of cable. 
We propose to adopt these industry standards in lieu of our own 
prescriptive standards.
    In Sec.  111.60-5(a), the Coast Guard currently requires that cable 
installations meet the recommended practices contained in IEEE 45-2002, 
and we excluded the section concerning cable splices. Now we propose to 
update the edition to IEEE 45.8-2016 and remove the exclusion for the 
section on cable splices because it is inconsistent with other 
regulations to exclude them. The existing and proposed regulations 
regarding cable splices in Sec.  111.60-19 refer to IEEE 45's 
recommendations for cable splices.
    Additionally, in Table 111.60-7--Demand Loads, we propose minor 
edits to make ``bus-tie'' and ``feeder'' plural where they appear in 
the table. As previously mentioned in the IBR updates to Sec.  110.10-
1, we would also update the NFPA NEC 2002 standard to its newer edition 
NFPA 70, where it appears in the table.

D. IEC 60092-502 Electrical Installations in Ships--Part 502: Tankers--
Special Features

    We propose to accept IEC 60092-502:1999 as an option for 
classification of hazardous locations (areas) in the new Sec.  111.105-
50(a). Section 111.105-50(a) would contain alternative standards for 
the classification of hazardous locations requirements in Sec. Sec.  
111.105-29, 111.105-31, 111.105-32, 111.106-9 and 111.106-11 of this 
subchapter. This IEC standard is referenced in SOLAS II-1/45.11, the 
International Code of the Construction and Equipment of Ships Carrying 
Liquefied Gases in Bulk section 10.1.1, the International Code for the 
Construction and Equipment of Ships Carrying Dangerous Chemicals in 
Bulk section 10.1.2.1, and all major classification societies' rules. 
Allowing this option will provide system designers with the flexibility 
to classify and specify equipment for hazardous locations using the 
same scheme used internationally.
    IEC 60092-502:1999 is currently accepted for use by vessels in the 
Coast Guard's Alternate Compliance Program when supplemented with 
``USCG Supplemental Requirements for use of IEC 60092-502:1999 for 
application of SOLAS regulation II-1/45.11 to U.S.-flag vessels.'' \2\ 
The Coast Guard developed these supplemental requirements to ensure an 
equivalent level of safety as the requirements of subpart 111.105. In 
this rulemaking, we propose to accept IEC 60092-502:1999 without the 
supplement. This edition of the standard has been published for over 15 
years and we are not aware of any casualty history attributed to its 
use as compared to vessels complying with the applicable U.S. 
regulations. For these reasons, we propose it as an option for U.S. 
vessels.
---------------------------------------------------------------------------

    \2\ See Commercial Vessel Inspection Alternatives and Delegated 
Functions available at https://www.dco.uscg.mil/Our-Organization/Assistant-Commandant-for-Prevention-Policy-CG-5P/Commercial-Regulations-standards-CG-5PS/Office-of-Standards-Evaluation-and-Development/US-Coast-Guard-Regulatory-Development-Program-RDP-/Alternate-Compliance-Program/.
---------------------------------------------------------------------------

    In Sec.  111.105-50(c), we propose to add that if IEC 60092-
502:1999 is used for hazardous locations classifications, then the 
applicable ventilation requirements for cargo handling rooms on tank 
vessels in subchapter D would apply. This is not a new requirement, but 
it is placed here to ensure system designers do not assume that 
compliance with the ventilation standards in IEC 60092-502:1999 is 
sufficient.

E. Emergency Generator in Port

    We propose in the new Sec.  112.05-7 to allow the emergency 
generator to be used in port, provided supplemental safety standards 
are in place. The current regulations in Sec.  112.05-1 requires that 
the emergency source of power must be dependable, independent, and 
dedicated. The purpose of these requirements in Sec.  112.05-1 is that 
emergency power must be immediately and dependably available in the 
event of a loss of the ship's service power. For decades this has been 
achieved by installation of a dedicated and independent emergency 
generator.
    In the late 1990s, the International Association of Classification 
Societies proposed a unified interpretation to the IMO in light of 
improvements in automation and potential environmental benefits. That 
proposal incorporated a set of additional safety standards in order to 
allow the use of an emergency generator during lay time in port. This 
interpretation, with the supplemental safety standards, would encourage 
the use of a more appropriately sized generator for lay time loads 
instead of an overly large ship service generator while simultaneously 
assuring the availability of emergency power. Predicated on the premise 
that this proposal provided an equivalent level of safety, it was 
subsequently adopted by the IMO in 2005, promulgated in IMO circular 
MSC/Circ.1176 dated 25 May 2005 and updated in IMO circular MSC.1/Circ. 
1464/Rev.1 dated 24 Oct. 2013. Since then, most classification 
societies and flag States have harmonized their rules to align with 
this interpretation.
    Similar to the determination made by the IMO, we propose to allow 
use of emergency power systems that incorporate a generator with the 
additional safeguards similar to those prescribed by the IMO. The 
additional safeguards provide an equivalent level of safety as the 
existing requirements in part 112 as well as other potential 
operational benefits. With respect to providing a dependable source of 
emergency power, operation of the emergency generator in port does not 
decrease the dependability of the emergency power system. On the 
contrary, regular operation of the generator with the associated 
planned maintenance scheme required by MSC.1/Circ.1464/Rev.1 will 
result in increased dependability and crew familiarity and an improved 
readiness of the system should an emergency situation occur. Further, 
the additional requirements related to load shedding,

[[Page 21458]]

fuel and lubrication oil systems, generator and switchboard 
construction, power management, and operational instructions will 
ensure the dedicated and independent operation of this system in an 
emergent situation and solely provide service to the emergency power 
system. Overall, this system will deliver additional flexibility to the 
crew while ensuring the availability of a dedicated source of power in 
the event of an emergency. The proposed arrangements will result in 
improved performance, better fuel economy, lower emissions, and higher 
reliability than less integrated systems.
    For these reasons, we propose to allow the emergency generator to 
be used in port provided that supplemental safety standards are in 
place. The supplemental safety standards proposed in Sec.  112.05-7 are 
similar to those prescribed in MSC.1/Circ.1464/Rev.1 as well as section 
4-8-2/5.17 of the ABS Marine Vessel Rules.

F. Description of Additional Proposed Changes Within Subchapter J

Section 110.15-1 Definitions
    We propose a more descriptive definition of ``deadship'' that 
aligns with 4-1-1/1.9.6 of the ABS Marine Vessel Rules and IEC 60092-
201:2019.
    The definition of a ship's service loads and drilling loads would 
be moved from Sec.  111.10-1(a) to Sec.  110.15-1 so all definitions 
are in one location.
Section 110.25-1 Plans and Information Required for New Construction.
    We propose to consolidate the hazardous locations plan submittal 
requirements of the existing Sec.  110.25-1(i), (p), and (q) into a 
single section. The Offshore Supply Vessels of at Least 6,000 GT ITC 
interim rule (79 FR 48893, Aug. 18, 2014) and the Electrical Equipment 
in Hazardous Locations final rule (80 FR 16980, Mar. 31, 2015) included 
plan submittal requirements, Sec. Sec.  110.25-1(p) and (q), 
respectively. As explained in Section V, we propose to offer all types 
of vessels and facilities the same selection of explosion protection 
standards. Therefore, the plan submittal requirements are identical and 
three separate sections are no longer required.
Section 111.05-3 Design, Construction, and Installation; General
    In Sec.  111.05-3(c), the grounding requirements for appliances and 
tools would be clarified so that they are consistent with current 
industry practice.
Section 111.10-9 Ship's Service Supply Transformers; Two Required
    The note to Sec.  111.10-9 has been revised to clarify that 
transformers located downstream of the ship's service switchboard are 
not required to be provided in duplicate. This is an item regularly 
misunderstood and is explained on page 16 of the Navigation and Vessel 
Inspection Circular (NVIC) 2-89, ``Guide for Electrical Installations 
on Merchant Vessels and Mobile Offshore Drilling Units'', dated Aug. 
14, 1989.\3\
---------------------------------------------------------------------------

    \3\ NVIC 2-89 ``Guide for Electrical Installations on Merchant 
Vessels and Mobile Offshore Drilling Units'' is available at https://www.dco.uscg.mil/Portals/9/DCO%20Documents/5p/5ps/NVIC/1989/n2-89.pdf.
---------------------------------------------------------------------------

Section 111.12-11 Generator Protection
    In this section and many other sections, the term ``semiconductor 
rectifier (SCR)'' has been replaced with ``semiconductor converter'', a 
term now more commonly used in industry.
Section 111.12-13 Propulsion Generator Protection
    This section on propulsion generator protection would be deleted 
because it is simply a reference to Sec.  111.35-1. This cross 
reference is not necessary.
Section 111.15-10 Ventilation
    In Sec.  111.15-10(b)(2)(i), the IEC equivalent classification of 
Class I, Division 1, Group B would be added as an alternate standard.
Section 111.25-5 Marking
    We propose to delete this section because the requirements for 
motor markings are sufficiently addressed by the referenced ABS Marine 
Vessel Rules.
Section 111.30 Switchboards
    The requirements for switchboards contained in IEEE 45 2002 would 
be replaced with requirements from the recently published IEEE 45.7 
(2012).
    This proposed rule would add a note to Sec.  111.30-5 warning that 
the interchangeability and compatibility of components complying with 
both IEEE and IEC cannot be assumed, to address the growing use of 
components meeting IEC standards on U.S. vessels.
    The flame retardant test standard IEC 332-1 has been superseded by 
IEC 60332-1-1:2015 and IEC 60332-1-2:2015. We propose to update the 
standards for the flame retardant test in Sec.  111.30-19(b)(4) 
regarding buses and wiring.
    The term ``pilot light'' would be replaced with the more commonly 
used term ``indicator light.''
Subpart 111.33 Power Semiconductor Rectifier Systems
    The requirements for semiconductor converters contained in IEEE 45 
2002 are being replaced with requirements from the recently published 
of IEEE 45.2 (2012).
Section 111.50-3 Protection of Conductors
    In Sec.  111.50-3(b)(2), the requirements for steering gear 
circuits is being changed from subchapter F to a more specific cite of 
Sec.  58.25. Reference to IEC 92-202 has been removed from Sec.  
111.50-3(c). This standard does not address standard ratings for fuses 
or circuit breakers.
Subpart 111.51 Calculation of Short-Circuit Currents and Subpart 111.52 
Coordination of Overcurrent Protective Devices
    We propose to combine subparts 111.51 and 111.52 into new subpart 
111.51 to more clearly and concisely present the requirements for 
coordination of overcurrent protection devices and calculation of 
short-circuit currents. The general discussion contained in current 
Sec.  111.51-1 is based on IEC 60092-202:2016.
    The short-circuit calculations requirements of proposed Sec.  
111.51-2(a) are from the existing Sec.  111.52-1. The proposed Sec.  
111.51-2(b) would clarify that the calculations must be performed to 
select suitably rated equipment and protective devices. The short-
circuit calculations requirements of the proposed Sec. Sec.  111.51-3 
and 111.51-5 are from the existing Sec. Sec.  111.52-3 and 111.52-5, 
respectively.
    NAVSEA DDS 300-2 is proposed for deletion because it is no longer 
available. IEC 61660-1:1997 would be added as a standard for DC 
systems.
    The requirements for the protection of vital equipment, Sec.  
111.51-6, is from the existing Sec.  111.51-3.
Section 111.54-1 Circuit Breakers
    In Sec.  111.54-1(c)(2), the maximum voltage for direct-current 
circuit breakers meeting IEC 60947-2:2013 has been identified as 1500 
V. This is in accordance with that standard.
Section 111.75-17 Navigation Lights
    In Sec.  111.75-17(a), we propose to remove the requirement that 
the navigation light indicator panel be supplied by a feeder directly 
from the emergency switchboard. The panel will still be required to be 
supplied from the

[[Page 21459]]

emergency switchboard but this change allows for the common practice of 
suppling the navigation lights from an emergency lighting panel rather 
being directly fed from the switchboard. This is consistent with 
industry practice and vessel classification society rules. As part of 
this change we are also proposing to delete Sec.  112.43-13 which 
provided details on the navigation light panel feeder.
    In Sec.  111.75-17(d)(2), we propose to offer EN 14744 as an 
alternative for certification of navigation lights. UL 1104 is the 
other acceptable standard, but it has not been updated in over 20 years 
and addresses neither LED light sources nor EMC testing. The other 
construction and testing requirements of EN 14744 are not identical to 
UL 1104, but it is accepted worldwide. It addresses LED lights and EMC 
testing and has been published for 15 years. We are unaware of any 
safety concerns related to it. For these reasons, we feel it is an 
acceptable option for certification of navigation lights. Navigation 
lights constructed and tested to the requirements of EN 14744 have been 
accepted by the Coast Guard on a case-by-case basis subject to the 
additional requirements of the USCG Marine Safety Center's Marine 
Technical Note 01-18, Guidance for Establishing Equivalency to UL 1104 
Navigation Lights.\4\ We propose to accept EN 14744 without these 
additional requirements.
---------------------------------------------------------------------------

    \4\ See https://www.dco.uscg.mil/Portals/9/MSC/MTN/MTN.01-18.07.16.18.LEDandEUNavigationLights.pdf.
---------------------------------------------------------------------------

    Additionally in Sec.  111.75-17(d)(2), the requirements for battery 
powered navigation lights have been clarified. The existing text has 
been misinterpreted on occasion. These lights must be certified by an 
independent laboratory to the applicable requirements of UL 1104 or EN 
14744, as must all navigation lights. This ensures they meet the 
applicable requirements of the International Regulations for Preventing 
Collisions at Sea, 1972 (72 COLREGS) and the Inland Navigation Rules 
(33 CFR 83).
    We propose deleting the requirements for a flashing light in the 
existing Sec.  111.75-17(d)(4), because these requirements are 
contained in section 22.11 of UL 1104 and section 4.4 of EN 14744.
Section 111.75-18 Signaling Lights
    We propose deleting the outdated, prescriptive requirements on 
signaling lights in this section that were based on the applicable 
international requirements in 1996 and incorporating by reference ISO 
25861. This standard provides performance requirements for daylight 
signaling lamps pursuant to chapter V of SOLAS, 1974, as amended and 
chapter 8 of the International Code for Safety for High-Speed Craft. 
Further, since 2002, navigation equipment required by chapter V of 
SOLAS, including signaling lamps (or lights), have been required to be 
type approved by the administration.
Section 111.75-20 Luminaires (Lighting Fixtures)
    Throughout this section, we propose replacing the term ``lighting 
fixture'' with the internationally used term ``luminaire'' and we 
propose removing the prescriptive requirements contained in this 
section. Lighting fixtures meeting the standards incorporated by 
reference in this section, UL 1598A, or IEC 60092-306:2009, are 
suitable for use on vessels. Further, this rule would specify the 
clauses of UL 1598A applicable to nonemergency and inside-type 
decorative luminaires.
Section 111.83-7 High Voltage Shore Connection
    We propose adding in this new section a standard for high voltage 
shore connection systems, IEC/IEEE 80005-1:2019, applicable to ships 
required by state or local law to connect to shore power. The Coast 
Guard has actively participated with state and local stakeholders, 
shoreside and marine industry representatives, and equipment 
manufacturers to develop a standard to safely connect to high voltage 
shore connections. This standard is offered as an option for compliance 
with state or local law.
Section 111.99-3 Definitions
    We propose removing this section of definitions. Fire door holding 
and release systems, if fitted, must meet SOLAS II-2/9.4.1.1.5.3. This 
reference has been updated based on the reorganization of SOLAS Chapter 
II-2. These definitions are no longer necessary.
Section 111.103 Remote Stopping Systems
    The wording of 46 CFR 111.103 has caused confusion due to the order 
of the subsection with readers inferring that machinery space 
ventilation is a separate category from the ventilation referred to by 
46 CFR 111.103-7. We propose editorial changes to this section to 
clarify its intent.
Subpart 111.105 Hazardous Locations
    The Coast Guard has completed two recent rulemaking projects 
related to hazardous locations, the ``Offshore Supply Vessels of at 
Least 6,000 GT ITC'' interim rule (79 FR 48893, Aug. 18, 2014) and the 
``Electrical Equipment in Hazardous Locations'' final rule (80 FR 
16980, Mar. 31, 2015). We propose to revise subpart 111.105 (Hazardous 
Locations) to be consistent with these two sets of regulations. This 
would expand the list of acceptable national and international 
explosion protection standards, providing more options for operators.
    We propose adding the internationally accepted independent third-
party certification system, the International Electrotechnical 
Commission System for Certification to Standards relating to Equipment 
for use in Explosive Atmospheres (IECEx), as an accepted method of 
testing and certifying electrical equipment intended for use in 
hazardous locations. Existing Sec.  111.108-1(b) allows owners and 
operators of existing U.S. MODUs, floating Outer Continental Shelf 
(OCS) facilities, vessels other than Offshore Supply Vessels (OSVs), 
and U.S. tank vessels that carry flammable or combustible cargoes, the 
option of using the same expanded list of standards and the IECEx 
System. In amending subpart 111.105, we propose incorporating these 
standards so that they are available to all vessels and facilities that 
must comply with subchapter J.
    In Sec.  111.105-17(a)(1)(i), we propose adding three new standards 
for equipment in hazardous locations, UL 783, ANSI/ISA 12.12.01, and 
ANSI/UL 2062. See section VI.A for further explanation of each 
standard.
    In Sec.  111.105-17(b), we propose adding additional, acceptable 
standards for the use of conduit, IEC 61892-7:2019, IEC 60092-502:1999, 
API RP 14, and API RP 14FZ. See section VI.A for further explanation of 
each standard.
    In the new Sec.  111.105-28, we propose adding ASTM F2876-10 to 
address internal combustion engines in hazardous locations. Under the 
proposed section, internal combustion engines installed in Class I 
Divisions 1 and 2 would be required to meet the provisions of ASTM 
F2876-10. Like the expanded list of standards for electrical equipment 
in hazardous locations, this standard in subparts 111.106 and 111.108 
is the result of previous rulemaking projects and would be added to 
Sec.  111.105-28. This will ensure a consistent standard for these 
installations on all vessel and facility types.
    In Sec.  111.105-31(e), we propose providing the option for 
submerged cargo pumps that do not meet Sec.  111.105-31(d) to receive 
concept

[[Page 21460]]

approval by the Commandant (CG-ENG) and plan approval by the Commanding 
Officer, MSC. This is consistent with the existing Sec. Sec.  111.106-
3(f) and 111.108-3(f).
    In Sec.  111.105-31(f), we propose deleting reference to IEEE 45 
1998 and IEC 60092-502:1999 because these do not provide any additional 
information on classification of cargo tanks beyond what is currently 
in subchapter J.
    In Sec.  111.105-31(o), we propose clarifying the requirements for 
systems installed in duct keels.
    In Sec. Sec.  111.105-35 and 111.105-45, we propose updating the 
IEC classification notation in accordance with IEC 60079-10-2:2015.
    In Sec.  111.105-41, we propose removing the reference to IEEE 45 
1998 because the standard has been superseded.
Subpart 111.106 Hazardous Locations on OSVs
    In Sec.  111.106-3(b)(1)(i), we propose to add three new standards 
for equipment in hazardous locations, UL 783, ANSI/ISA 12.12.01, and 
ANSI/UL 2062. See section VI.A for further explanation of each 
standard.
Section 111.107-1 Industrial Systems
    In Sec.  111.107-1(b), we propose to clarify the standards for 
switchgear. Currently Sec.  111.107-1(b)(1) refers to an unnecessarily 
broad range of standards. We propose to simplify this section by cross 
referencing the specific sections of the existing regulations in 
subpart 111.30 that apply to switchgears.
Subpart 111.108 Hazardous Locations Requirements on U.S. and Foreign 
MODUs, Floating OCS Facilities, Vessels Conducting OCS Activities, and 
U.S. Vessels That Carry Flammable and Combustible Cargo
    We propose to remove paragraph (b) from Sec.  111.108-1. Paragraph 
(b) of this section is a cross-reference to the expanded list of 
standards and the IECEx System in subpart 111.105; the paragraph is 
directed to owners and operators of existing U.S. MODUs, floating OCS 
facilities, vessels other than OSVs, and U.S. tank vessels that carry 
flammable or combustible cargoes. This cross reference to subpart 
111.105 would no longer be necessary because we propose to include the 
same standards and systems in Sec.  111.108-3 (General requirements).
    In Sec.  111.108-3(b)(1)(i), we are adding three new standards for 
equipment in hazardous locations: UL 783, ANSI/ISA 12.12.01, and ANSI/
UL 2062. See section VI.A for further explanation of each standard.
Section 112.01-20 Final Emergency Power Source
    We propose to clarify the description of the final emergency power 
source. For the convenience of the reader, we also propose cross-
referencing Sec.  112.15-5, which specifies the existing regulations 
for final emergency power sources.
Section 112.05-5 Emergency Power Source
    In Sec.  112.05-5(a), we are clarifying that the emergency power 
source must be sized using a unity (1.0) service factor on all loads 
required by Table 112.05-5(a). This section currently states that the 
emergency power source must simultaneously supply these loads. When 
sizing the emergency power source to meet this requirement the loads in 
Table 112.05-5(a) must have a service factor of unity, 1.0 or 100%. 
This is also referred to as a load factor. This is not a change to the 
existing requirement but only a clarification of the requirement that 
the emergency power source will be appropriately sized to accomplish 
this task.
Section 112.15-1 Temporary Emergency Loads
    In Sec.  112.15-1(s), we propose to add the engineer's assistance-
needed alarm to the list of loads that must be powered by the temporary 
emergency power source. This is consistent with the requirement in 
Sec.  113.27-1(c) that states it must be powered from the same source 
as the general alarm.
Section 112.43-13 Navigation Light Indicator Panel Supply
    We propose to delete this requirement because the navigation light 
indicator panel supply is proposed to no longer be required by Sec.  
111.75-1(a) to be directly supplied by a feeder from the emergency 
generator but can be supplied by an electrical panel, such as an 
emergency lighting panel, which is supplied by the emergency 
switchboard.
Section 112.50-1 General
    In Sec.  112.50-1(g), we propose to delete the requirement that 
emergency generators automatically shut down upon loss of lubricating 
oil pressure. This section would continue to require that generators be 
set to shut down automatically upon overspeed or operation of a fixed 
fire extinguishing system in the emergency generator. Removing the 
requirement for emergency generators to automatically shut down in case 
of loss of lubricating oil pressure is consistent with classification 
society rules and allows the crew to decide in an emergency situation 
if the emergency generator should be shut down. We also propose to 
reformat Sec.  112.50-1(g) to clarify the remaining regulations for 
emergency generator set shut downs.
    In addition, we propose to revise the format of paragraph (h) to 
clarify that the alarms are required for all of the listed conditions 
in each section, not just one of the two conditions listed in each 
section. This is a nonsubstantive formatting edit that would not affect 
the existing alarm regulations for emergency generators in Sec.  
112.50-1(h).

VII. Incorporation by Reference

    Material proposed for incorporation by reference appears in Sec.  
110.10-1, and is summarized and discussed in section VI.A of this 
preamble. Copies of the material are available from the sources listed 
in Sec.  110.10-1, and we believe they are generally available to or 
already in use by the class of persons potentially affected by this 
proposed rule. The standards we are proposing to incorporate by 
reference are available either at the publisher's web address included 
in the proposed regulatory text of Sec.  110.10-1 or by contacting the 
publisher listed in the standard. With this proposed rule, we also 
reviewed and updated all the publisher's web addresses listed in 
proposed Sec.  110.10-1 to ensure they are current. The following list 
of publishers offer some of the more recent standards we propose to 
incorporate at no cost to the public: ABS, FM Approvals, IMO, Lloyd's 
Register, NFPA, DDS/Military Handbook, and UL. Based on the volume of 
equivalency requests the Coast Guard receives asking us to confirm that 
the latest edition is equivalent or better than the edition currently 
incorporated, we believe industry already has access to and uses these 
more recent standards. The affected industry typically obtains the more 
recent editions of standards in the course of their business, in order 
to address advancements in technology.
    You may also contact the person in the FOR FURTHER INFORMATION 
CONTACT section for additional direction on how to obtain access to 
electronic copies of the materials. Before publishing a binding rule, 
we will submit this material to the Director of the Federal Register 
for approval of the incorporation by reference.

VIII. Regulatory Analyses

    We developed this proposed rule after considering numerous statutes 
and Executive orders related to rulemaking. A summary of our analyses 
based on these statutes or Executive orders follows.

[[Page 21461]]

A. Regulatory Planning and Review

    Executive Orders 12866 (Regulatory Planning and Review) and 13563 
(Improving Regulation and Regulatory Review) direct agencies to assess 
the costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health and safety effects, distributive impacts, and equity). Executive 
Order 13563 emphasizes the importance of quantifying both costs and 
benefits, of reducing costs, of harmonizing rules, and of promoting 
flexibility.
    The Office of Management and Budget (OMB) has not designated this 
proposed rule a significant regulatory action under section 3(f) of 
Executive Order 12866. Accordingly, OMB has not reviewed this proposed 
rule. Details on the estimated cost savings of this rule can be found 
in the rule's regulatory analysis (RA) that follows.
    The Coast Guard proposes to update subchapter J of title 46 of the 
CFR. This proposed rule would align the standards, which govern 
electrical equipment and installations on U.S.-flagged vessels, with 
current industry practices to ensure that the standards are consistent 
on all vessel types that we reference in subchapter J. The provisions 
of this proposed rule would update existing standards through 
incorporation by reference, provide options to use alternative 
standards, eliminate obsolete standards, and clarify the existing 
requirements. The majority of the updates would simply incorporate by 
reference the more recent versions of the same standards with little or 
no substantive change. The more recent editions reflect more modern 
technologies, terminology, and practices. By updating standards, we 
expect the proposed rule to generate cost savings to industry and the 
Federal Government of approximately $204,695 over a 5-year period of 
analysis in 2019 dollars, using a 7-percent discount rate (we are using 
a 5-year period of analysis because we anticipate this proposed rule 
would not produce cost savings beyond this time period). We estimate 
annualized cost savings to be approximately $49,923, using a 7-percent 
discount rate. The cost savings are a result of industry submitting 
fewer equivalency requests to the Coast Guard, which we base this cost 
savings analysis upon. We also expect the proposed rule to generate 
unquantified benefits because incorporating these standards would 
simplify regulatory compliance, reduce confusion, and provide industry 
flexibility. Table 2 provides a summary of the impacts of the proposed 
rule.

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

Affected Population
    There are numerous provisions of this proposed rule that affect 
four parts in subchapter J of title 46 of the CFR (110, 111, 112, and 
113), as well as multiple subparts within each part. Subchapter J 
applies to vessels covered by subchapters D, H, I, I-A, K, L, O, R, and 
U.\5\
---------------------------------------------------------------------------

    \5\ Title 46 CFR subchapter J lists two other subchapters, Q and 
W. Subchapter Q does not contain vessels; it applies to vessels in 
the other subchapters regarding equipment, construction, and 
materials for specifications and approval. Similarly, subchapter W 
does not contain vessels but applies to vessels that have lifesaving 
appliances and arrangements in one of the subchapters previously 
listed. Subchapter O contains tank barges and freight barges.
---------------------------------------------------------------------------

    This proposed rule would affect approximately 5,570 existing, 
inspected U.S.-flagged vessels. We obtained the affected population of 
this proposed rule from our Marine Information for Safety and Law 
Enforcement (MISLE) database. For standards we are incorporating by 
reference in this proposed rule, we expect all U.S.-flagged vessel 
owners and operators to use the most recent incorporated standards, 
some of which were updated as recently as last year. For construction 
standards, we expect all U.S.-flagged vessel owners and operators to 
use the most recent incorporated standards that are in place at the 
time of construction or modification of a vessel and for vessels to 
meet the most recent incorporated standards when they enter service.
    For the purpose of the cost savings analysis, we use a subset of 
the total affected population because only owners and operators of new 
U.S.-flagged vessels entering service annually would generate cost 
savings by submitting fewer equivalency requests to the Coast Guard. 
Included in the total population of 5,570 vessels are 1,051 new U.S.-
flagged vessels that entered service in the last 5 years, from 2014-
2018. We divided 1,051 by 5 years to obtain an average of approximately 
210 new U.S.-flagged vessels annually. See table 3 below. We based the 
cost savings analysis on the past number of equivalency requests owners 
and operators of new U.S.-flagged vessels submitted to the Coast Guard 
over the past 18 months, or from September 2018 to February 2020. The 
number of equivalency requests the Coast Guard received from owners and 
operators of the 210 vessels during this period was 10 annually. Prior 
to this time period, the Coast Guard did not collect data on 
equivalency requests.
    We expect this proposed rule would reduce the baseline number of 
equivalency requests the Coast Guard would receive from industry by 80 
percent.\6\ Although this rulemaking will update standards, we expect a 
certain number of standards to be out of date

[[Page 21462]]

each year because standards organizations are continuously revising 
them for safety concerns in addition to maintaining pace with the 
technological advancements within the industry. Meaning, this proposed 
rule would reduce the number of equivalency requests by 80 percent 
annually. This in turn, would leave about 20 percent of the public who 
still may have questions about the standards they are using annually 
during the 5-year period. Alternatively stated, we do not expect this 
proposed rule or any updates to standards to eliminate the public's 
questions altogether. So we expect the number of equivalency requests 
that we receive from the public to be about 20 percent annually. The 
Coast Guard makes a determination in the year we receive a question 
(equivalency request) from the public; therefore, the questions would 
not accumulate from one year to the next. For example, if we 
characterize the number of questions in the first year as 100 percent 
of the total amount, we expect this proposed rule to reduce the number 
of questions by 80 percent in this year, which produces the cost 
savings. As a result, the balance of 20 percent is the amount that 
remains, which comprises the number of questions in the first year. In 
the second year, the public generates additional questions based on the 
standards they are using, which do not add to the number of questions 
in the first year. Again, we treat the number of questions in the 
second year as 100 percent of the total amount and we expect this 
proposed rule to reduce the number of requests by 80 percent in this 
year, as we explained above. This again, leaves an amount of 20 
percent, which comprises the number of questions in the second year. 
Essentially, the number of questions in a subsequent year replaces the 
number of questions the Coast Guard resolves in the preceding year. 
This process continues through to the fifth year of the analysis period 
when standards organizations, again, create updates to existing 
standards.
---------------------------------------------------------------------------

    \6\ Generally, standards get updated every 5 years. We therefore 
assume that 20 percent of the standards become outdated each year as 
time elapses, so 100 percent/5 years = 20 percent annually (outdated 
standards). So, the remaining 80 percent (100 percent-20 percent) 
would generate the cost savings.
---------------------------------------------------------------------------

    Specifically, we expect owners and operators of new U.S.-flagged 
vessels that enter service to submit two equivalency requests annually, 
or a reduction of eight equivalency requests annually. Owners and 
operators of new U.S.-flagged vessels submit equivalency requests to 
the Coast Guard to ask for approval to use a standard that is not in 
regulation but may be equivalently safe. Equivalency requests are 
explained in greater detail in the Cost Savings Analysis portion of 
this analysis.

    As indicated in the section V of the preamble, this proposed rule 
continues the Coast Guard's response to the Presidential Regulatory 
Reform Initiative of Mar. 4, 1995, and directives including Executive 
Orders 12866 and 13563 that are intended to improve regulation and the 
regulatory process. The provisions of this proposed rule would remove 
obsolete regulations, revise current regulatory text, substitute 
performance-based options for regulatory compliance as opposed to 
conventional prescriptive solutions, and incorporate by reference more 
recent national and international industry standards into the CFR. The 
Coast Guard recognizes the significant technological advances in 
electrical engineering equipment, systems, and devices carried on 
vessels. As a result, this proposed rule would encourage the use of 
newer equipment and promote adherence to modern standards in the 
industry. Industry also would not realize cost savings from not having 
to send equivalency requests to the Coast Guard. See table 4 for how 
parts of the CFR would be affected by this proposed rule along with the 
anticipated impacts.
Benefits of the Proposed Rule
Cost Savings Analysis
    We divided all of the changes of the proposed rule into three 
categories, which we present in table 4: (1) Editorial changes to the 
CFR; (2) Updates to IBRs with technical changes; and (3) IBRs with 
proposed options or alternative options.
    First, we propose to make editorial changes to subchapter J that 
include such items as the removal of outdated terminology and the 
consolidation of text in different paragraphs into one paragraph, which 
includes regulatory provisions in 46 CFR parts 110, 111, 112, 113; we 
expect these changes to be a no cost change.
    Second, we propose updates to IBRs that have technical changes, 
which includes regulatory provisions in numerous subparts of 46 CFR 
parts 110, 111, and 113. It is standard practice in vessel 
manufacturing to follow the most recent editions of standards developed 
by representative groups of experts using a consensus-based process, 
because most manufacturers also supply materials to vessels not 
required to comply with 46 CFR subchapter J. Manufacturers of certain 
types of electrical equipment carried on vessels are currently 
producing equipment to the more recent standards, most of which have 
been published for at least

[[Page 21463]]

several years and all of which have been developed by standard-based 
development organizations. These more recent standards, which this 
proposed rule would codify, provide clarity and specificity to outdated 
technical standards they are replacing; therefore, we expect these 
changes to be a no cost change.
    Thirdly, for IBR standards that are one of several available 
standards as referenced in subchapter J, we propose to update standards 
with their more recent edition (these would be alternative options) and 
add standards as new options to the several other available standards 
for vessel owners and operators, and manufacturers of certain types of 
electrical equipment. These options combined would provide industry the 
opportunity to remove overly prescriptive requirements, would simplify 
regulatory compliance, and provide regulatory flexibility. Many of the 
options, some of which are alternative options and others new, would be 
IBR items that affect multiple subparts of 46 CFR parts 110, 111, and 
113. The remaining options would not be IBR items and would affect 
multiple subparts of 46 CFR parts 111 and 112. The options we propose 
to incorporate by reference would apply to the same population of 5,570 
vessels. We assume industry would use the more recent national and 
international standards referenced in the proposed rule. We expect 
adding a revised or new standard as an additional option to the 
exisiting standards would be a no cost change because the new or 
revised standard does not have to be chosen. See table 4.
    Specifically, we propose the following four changes to subchapter 
J, related to generator prime movers, electrical cable construction, 
hazardous locations, and emergency generators, in order to eliminate 
outdated or unnecessarily prescriptive electrical engineering 
regulations and add a limited number of alternative standards. Of the 
four items listed in the following text, the generator prime mover 
falls into the second (IBRs with technical changes), electrical cable 
construction, emergency generator, and hazardous locations fall 
primarily into the third category (IBRs with proposed and alternative 
options), which we listed previously.
Generator Prime Mover
    The proposed rule would eliminate the regulatory requirements in 
Sec.  111.12-1(b) and (c) for each generator prime mover to have an 
independent overspeed device and a loss of lubricating oil pressure to 
the generator bearing shutdown. The ABS rules, already incorporated by 
reference in Sec.  111.12-1(a) since 1965, require these same 
safeguards on all but small generator prime movers. We also propose to 
incorporate by reference the ABS Steel Vessel Rules for generator prime 
movers without modification. Industry has been using these rules for 
many years and the removal of these requirements would not affect the 
performance of the generator prime mover. We expect this to be a no 
cost change.
Electrical Cable Construction
    For electrical cable construction requirements in subpart 111.60, 
the proposed rule would incorporate by reference the more recent 
editions of the 2017 IEC standards and 2017 editions of ANSI standards 
to ensure alignment with current technological trends and to eliminate 
several unnecessary prescriptive requirements. This proposed rule would 
align electrical cable standards in subpart 111.60 with standards 
accepted internationally by vessel classification societies and foreign 
administrations. This proposed rule would remove unnecessary, 
prescriptive requirements developed by the Coast Guard, which in turn, 
would simplify compliance. We expect this to be a no cost change 
because electrical cables are readily available that meet the standards 
that we would incorporate by reference with this proposed rule.
Hazardous Locations
    The proposed rule would amend subpart 111.105 by incorporating by 
reference the IEC standard 60092-502 as an alternative standard for 
classification of hazardous locations. This IEC standard, published in 
1999, is referenced in international standards and codes as well as all 
major classification societies' rules. Because we are adding an 
alternative standard and not changing requirements with this item, we 
expect this to be a no cost change.
Emergency Generator
    The proposed rule would amend subpart 112.05 to allow vessel owners 
and operators to use an emergency generator in port. Some U.S.-flagged 
vessel owners and operators favor the availability of this option in 
port because it is more fuel-efficient and results in less exhaust 
emissions than using the ship's larger service generators. This option 
is consistent with international guidance and classification society 
rules. However, this option would apply to a very small number of U.S.-
flagged vessel owners and operators who request it and the Coast Guard 
would approve the use of an emergency generator for vessel owners and 
operators in compliance with subchapter J only. We expect this option 
to have unquantified cost savings associated with it. We also 
anticipate unquantified benefits due to a decrease in exhaust emissions 
since an emergency generator would use less fuel than a ship's main 
generator.
    The proposed rule would create consistency between Coast Guard 
regulations and national and international standards through 
incorporation by reference, provide options with alternative standards, 
eliminate obsolete standards, and clarify the existing requirements 
through the changes we propose in 46 CFR subchapter J. We categorize 
the proposed changes in table 4, which summarizes the impacts of the 
proposed rule and the affected parts and subparts in subchapter J. For 
the purpose of this analysis, table 4 specifically lists all of the 
individual changes we propose by part, subpart, and paragraph of 46 CFR 
subchapter J. Table 1 in section III of the preamble is a general 
summary of the changes proposed in subchapter J.

Note: We may list the same citation of the CFR multiple times because we are proposing numerous changes to the
  same paragraph. These changes may include clarifications, deletions, or insertions of text. The term ``current
  industry standards'', means equipment manufacturers have been constructing equipment to the more recent
  editions of standards.

    The Coast Guard has evaluated the affected population and estimates 
that this proposed rule would generate cost savings for owners and 
operators of new U.S.-flagged vessels who would no longer submit 
equivalency requests to the Coast Guard's Marine Safety Center (MSC) 
for review. The proposed rule would also generate cost savings for the 
Federal Government, which would review fewer requests. An equivalency 
request is when an owner or operator of a new U.S.-flagged vessel sends 
questions to the Coast Guard to ask for a review of the standards they 
are currently using. Any member of the marine industry may submit a 
request, but it is primarily submitted by vessel owners and operators. 
Generally, the reason an owner or operator would make this request is 
to seek a determination from the Coast Guard on whether or not a 
standard not contained in Coast Guard regulations is sufficient for 
use. For example, a proposed equivalent standard could be a more recent 
edition of a standard in subchapter J or it could be an alternative 
standard not currently listed in subchapter J. A Coast Guard Marine 
Engineer compares the proposed equivalent standard with the standard 
incorporated by reference in subchapter J to ensure it offers an equal 
or greater level of safety.
    When evaluating the proposed alternative standard, we compared the 
standard that industry is using to the standard in subchapter J that 
addresses the type of engineering equipment under review. Typically, 
owners and operators of existing U.S.-flagged vessels (at the time of 
construction of a vessel and when a vessel enters service) use the more 
recent standards in subchapter J and therefore would not likely request 
an equivalency review from the Coast Guard. However, the Coast Guard 
expects owners and operators of new U.S.-flagged vessels that enter 
service each year to have some equivalency questions because they may 
not be familiar with all of the applicable regulations in subchapter J, 
which includes the most recent standards that are incorporated by 
reference.
    Based on MSC data, the Coast Guard received 15 equivalency requests 
over the period from September 2018 to February 2020; this is the only 
period of time the Coast Guard maintained equivalency data and is the 
most recent data we possess. This is equivalent to 10 requests 
annually.\7\ MSC data show that one vessel owner or operator submits 
one equivalency request annually, which the Coast Guard's Office of 
Design and Engineering Standards has validated. Generally, 
organizations such as UL and the IEC create electrical standards for 
industry that take into account updates in the latest technology and 
construction techniques for electrical equipment. These organizations 
usually review and update standards every 5 years. Therefore, based on 
a 5-year interval, we generally expect 20 percent of the standards to 
be out of date in a given year, which in turn, would create equivalency 
requests from industry. Because the Coast Guard makes a determination 
on an equivalency request in the same year it receives the request, we 
do not expect the number of equivalency questions to accumulate from 
year to year such that the 20-percent estimate would change in any year 
of a 5-year period. Even if we publish a rule to address updates to 
electrical standards in subchapter J, we still expect each year that 
the public will have questions about the standards it is using, which 
would generate equivalency requests on an annual basis; we do not 
expect a published rule to eliminate the public's questions altogether.
---------------------------------------------------------------------------

    \7\ The ratio of 15 requests divided by 18 months and made this 
equivalent to an unknown variable, or x, divided by 12 months. We 
obtain 18x, which is equivalent to 180 since x is equivalent to 10 
requests annually.
---------------------------------------------------------------------------

Industry Baseline Costs
    Without this proposed rule or under the current baseline, the Coast 
Guard receives approximately 10 equivalency requests annually. To draft 
an equivalency request to the MSC, an owner or operator of a U.S.-
flagged vessel would seek the services of an engineering design firm or 
a shipyard's technical staff for a Marine Engineer or Naval Architect 
to draft the equivalency request. Using the Bureau of Labor Statistics 
(BLS) ``Occupational and Employment Statistics'' database and May 2019 
wage estimates, the unloaded mean hourly wage rate for Marine Engineers 
and Naval Architects is $47.47 (occupational code 17-2121).\8\ To 
account for an employee's non-wage benefits, we applied a load factor 
to the

[[Page 21466]]

unloaded mean hourly wage rate, which we calculated by using BLS's 
``Employer Cost for Employee Compensation'' database. We determined the 
load factor to be approximately 1.50, rounded.\9\ We multiplied $47.47 
by 1.50 to obtain a loaded mean hourly wage rate of approximately 
$71.21 for this occupation.

2019, unloaded mean hourly wage rate for occupations in the United

    \9\ A loaded hourly wage rate is what a company pays per hour to 
employ a person, not the hourly wage an employee receives. The 
loaded hourly wage rate includes the cost of non-wage benefits 
(health insurance, vacation, etc.). To obtain the load factor, we 
used the multi-screen data search feature from this database and 
searched for ``private industry workers'' under ``total 
compensation'' and then for ``all workers'' in the category 
``Transportation and Materials Moving Occupations'', within the 
United States. We performed the same steps to obtain the value for 
``wages and salaries''. The series IDs for total compensation, and 
wages and salaries are CMU2010000520000D and CMU2020000520000D, 
respectively, which are not seasonally adjusted values. Using fourth 
quarter data for 2019, we divided the value for total compensation, 
$29.96 by wages and salaries, or $19.99, to obtain a load factor of 
about 1.50, rounded. https://data.bls.gov/cgi-bin/dsrv?cm.
---------------------------------------------------------------------------

    Based on information from the MSC and validated by subject matter 
experts in the Coast Guard's Office of Design and Engineering 
Standards, it takes a Marine Engineer or Naval Architect approximately 
40 hours of time to develop an equivalency request and submit it to the 
Coast Guard for review, which includes the electronic submission.
    We estimate the total undiscounted cost for industry to submit 10 
equivalency requests annually to be approximately $28,484, or $2,848 
for each request (10 equivalency requests x $71.21 x 40 hours per 
request). See table 5 for industry inputs.

Federal Government Baseline Costs
    When the Coast Guard receives an equivalency request from a vessel 
owner or operator (or an electrical equipment manufacturer), the Coast 
Guard personnel at the MSC must review the request to provide a 
determination on whether or not the proposed standard(s) is equivalent 
to standard(s) found in subchapter J. Based on information from the 
MSC, and validated by subject matter experts in the Coast Guard's 
Office of Design and Engineering Standards, a civilian Coast Guard 
Marine Engineer needs about 32 hours to review an equivalency request. 
This estimate is based on the past number of requests we received, or 
10 annually, as we presented earlier in this analysis. The Coast Guard 
expends approximately 8 weeks of time or 320 hours to review the 10 
requests. A Coast Guard Marine Engineer has a Federal Government grade 
level of a GS-14 (General Schedule), which has a loaded mean hourly 
wage rate of $106.\10\ We estimate the total, undiscounted cost for the 
Federal Government to review 10 equivalency requests annually to be 
approximately $33,920 (10 equivalency requests x 32 hours for each 
request x $106), or $3,392 for each request. See table 6 for the 
Federal Government inputs.
---------------------------------------------------------------------------

    \10\ We obtained the loaded mean hourly wage rates for civilian 
Federal Government personnel from a Coast Guard Instruction labeled 
``Commandant Instruction.'' This document also provides loaded wage 
rates for personnel in military service. The most recent version of 
this document is from February 2020, with a version number of 
7310.1U. Readers can view this document at https://media.defense.gov/2020/Mar/04/2002258826/-1/-1/0/CI_7310_1U.PDF. The

    We estimate the total, undiscounted baseline cost to industry and 
the Federal Government to submit and review equivalency requests, 
respectively, to be approximately $62,404 ($28,484 + $33,920), 
annually. Table 7 presents a summary of the baseline costs associated 
with industry submitting equivalency requests to the Coast Guard.

Industry Cost Savings
    The baseline costs we estimated for industry would be from vessel 
owners and operators of new U.S.-flagged vessels that enter service 
each year who submit equivalency requests. We expect this proposed rule 
would reduce the number of equivalency requests industry submits 
annually. We estimate 157 companies own the average number of 210 new 
U.S.-flagged vessels that have entered service each year in the past 5 
years. The number of equivalency requests the Coast Guard has received 
annually from these owners and operators is approximately 10 (a vessel 
owner or operator would request an equivalency determination without 
regard to the number of vessels owned). We anticipate standards 
organizations to update their standards every 5 years. Therefore, we 
expect 20 percent of the standards to be out of date in a given year 
over this period of time (100 percent divided by 5 years equals 20 
percent). We multiplied the 20 percent value by the baseline number of 
10 equivalency requests the Coast Guard receives annually from owners 
and operators of new U.S.-flagged vessels. Therefore, we expect 
industry to submit 2 equivalency requests (10 equivalency requests x 
0.20) in any given year of the analysis period or a reduction in the 
number of requests of 80 percent. Similarly, the marine industry would 
save approximately 320 hours annually from not drafting and submitting 
equivalency requests (320 hours = 8 requests x 40 hours for each 
request). The submission of an equivalency request would not affect or 
change an existing information collection request, nor would it create 
a new one because we estimate the number of requests to be 
approximately 2 annually, which is below the threshold of 10 in the 
Paperwork Reduction Act (PRA) of 1995. The Federal Government does not 
require the marine industry to submit these requests; vessel owners and 
operators (or manufacturers) would voluntarily submit requests only if 
they have questions about the standards they are using.
    Using the same labor category previously used to calculate the 
baseline

[[Page 21467]]

for industry costs, we estimate the total undiscounted cost savings of 
this proposed rule to industry to be approximately $22,787 annually 
[(10 equivalency requests x 40 hours for each equivalency x $71.21 = 
$28,484) minus (2 equivalency requests x 40 hours for each equivalency 
request x $71.21 = $5,697)]. We estimate 5-year cost savings of this 
proposed rule to industry to be approximately $93,432, using a 7-
percent discount rate. We estimate the annualized cost savings to be 
approximately $22,787, using a 7-percent discount rate. See table 8.

Federal Government Cost Savings
    With this proposed rule, we expect the number of equivalency 
requests the Coast Guard would review annually to be 2 (10 equivalency 
requests x 0.20). This again would be a reduction of 80 percent from 
the baseline number of 10 requests. With fewer equivalencies to review, 
the Coast Guard would also save approximately 256 hours annually from 
not reviewing equivalency requests (8 requests x 32 hours per request).
    Using the same labor category previously for MSC personnel to 
review an equivalency request, we estimate the total, undiscounted cost 
savings of the proposed rule to the Federal Government to be 
approximately $27,136 annually [(10 baseline equivalency requests x 32 
hours for each equivalency request x $106 = $33,920) minus (2 
equivalency requests x 32 hours for each equivalency request x $106 = 
$6,784)]. We estimate the 5-year discounted cost savings of this 
proposed rule to the Federal Government to be approximately $111,263, 
using a 7-percent discount rate. We estimate the annualized cost 
savings to be approximately $27,136, using a 7-percent discount rate.

Total Cost Savings of the Proposed Rule
    We estimate the 5-year, total discounted cost savings of the 
proposed rule to be approximately $204,695 ($93,432 + $111,263), using 
a 7-percent discount rate (see table 10). We estimate the annualized 
cost savings of the proposed rule to be approximately $49,923, using a 
7-percent discount rate. The total annualized cost savings is the 
summation of the values in tables 8 and 9 ($22,787 + $27,136 = $49,923) 
as a result of the reduction in the number of equivalency requests we 
expect annually from industry. See table 10.

Unquantified Cost Savings of the Proposed Rule
    We expect this proposed rule would have unquantified cost savings 
associated with the option of using an emergency generator while in 
port. The use of an emergency generator in port would likely save fuel 
because it would not require a vessel owner or operator to use a ship's 
larger service generators. However, we are not able to quantify the 
cost savings associated with this option because the Coast Guard does 
not have the data to predict how many vessel owners and operators would 
choose this option while in port. Nevertheless, we expect a very small 
number of vessel owners and operators to choose this option.
    Additionally, we expect this proposed rule to generate qualitative 
benefits. This proposed rule is necessary because it would update 
obsolete standards, remove redundancy in regulatory text, clarify and 
rearrange regulatory text, and provide options to owners and operators 
of vessels and manufacturers of certain types of electrical equipment. 
By updating standards and providing options, Coast Guard regulations 
would be less ambiguous and conform to the more recent industry 
standards, thereby ensuring consistency within the marine industry. 
Some of these options we consider to be alternative options and others 
would be new options. With these changes, industry would follow less 
ambiguous regulatory provisions, which we expect would create fewer 
equivalency requests.
    Regarding the proposed use of an emergency generator while in port, 
this option would likely reduce emissions and save fuel for vessel 
owners and operators who choose to use an emergency generator while in 
port. Some U.S.-flagged vessel owners and operators favor the 
availability of this option in port because it is more fuel-efficient 
and results in less exhaust emissions than using the larger ship's 
service generators. This would be an option for a very small number of 
U.S.-flagged vessel owners and operators who request it. This option is 
consistent with international guidance and classification society 
rules. The Coast Guard would approve the use of an emergency generator 
for vessel owners and operators in compliance with subchapter J only.
    We are not able to quantify the expected reduction in the exhaust 
emissions because the Coast Guard is not able predict how many vessel 
owners and operators would choose this option while in port due to lack 
of data.
Analysis of Alternatives
    (1) Industry would continue to meet the current standards in 46 CFR 
subchapter J with no updates to standards or incorporations by 
reference (current baseline without regulatory action).
    This alternative is a representation of the current state of the 
industry where vessel owners and operators would continue to follow 
standards in 46 CFR subchapter J without any updates to standards. To 
use a newer standard or alternative standard, industry must submit an 
equivalency request and Coast Guard must grant that equivalency. With 
this alternative, industry would not benefit from regulations 
incorporating newer or alternative standards and would not benefit from 
the latest advances in electrical equipment technology without 
incurring the cost of submitting equivalency requests. With this 
alternative, there would be no change in the costs.
    With this alternative, we would not update the standards in 46 CFR 
subchapter J and industry would not follow the more recent standards, 
which includes technological advancements in electrical equipment 
carried on vessels. We rejected this alternative because it would not 
create cost savings for the marine industry and industry also would not 
benefit from this alternative because it would not provide needed 
regulatory clarity.
    (2) Issuance of a policy letter that would permit the marine 
industry to meet the more recent editions of the IBR standards without 
updating the editions that are incorporated by reference in 46 CFR 
subchapter J.
    For this alternative, we would issue a policy letter that would 
permit industry members to meet the most recent editions of the 
pertinent standards. With such a policy in place, we anticipate that 
the marine industry would use the more recent editions of the IBR 
standards. However, 46 CFR Subpart J would still contain outdated 
standards and over prescriptive regulations that we could only remove 
through notice and comment rulemaking. Issuing a policy letter would 
not provide the agency an opportunity for soliciting public comment on 
current industry practice and standards. Additionally, the policy 
letter would not be enforceable against the public and the Coast Guard 
could revise the policy letter without opportunity to comment.
    We would expect the number of equivalency requests to decrease with 
this alternative by the same amount as the preferred alternative and we 
also expect the cost savings associated with this alternative to be the 
same as the preferred alternative. We estimate this alternative would 
save industry approximately $22,787 annually (undiscounted). We 
estimate the 5-year discounted cost savings of this alternative to 
industry to be approximately $93,432, using a 7-percent discount rate. 
We estimate the annualized cost savings to be approximately $22,787, 
using a 7-percent discount rate. We rejected this alternative because 
we would not be incorporating by reference the more recent standards in 
the CFR, industry would not benefit from enhanced regulatory clarity in 
subchapter J, and the public would not be given the opportunity to 
comment on the appropriateness of the more recent editions of the IBR 
standards.
    (3) Preferred Alternative--Update the IBR standards in 46 CFR 
subchapter J, create regulatory options, and make editorial changes to 
reduce the ambiguity that currently exists.
    With this alternative, we would update the current standards in 46 
CFR subchapter J and incorporate the more recent industry standards. 
This is the preferred alternative because it would create consistency 
between Coast Guard regulations and national and international 
standards, update the standards incorporated by reference to reflect 
the more recent standards available, provide options for alternative 
standards, eliminate obsolete standards, and clarify the existing 
requirements.

[[Page 21469]]

    This alternative would reduce the number of equivalency requests 
from the marine industry and create cost savings for vessel owners and 
operator and manufacturers of marine equipment. It would also reduce 
the hours the marine industry would spend on drafting and submitting 
equivalency requests to the Coast Guard. We analyzed and presented the 
cost saving impacts of this alternative earlier in this analysis.

B. Small Entities

    The Regulatory Flexibility Act of 1980 (5 U.S.C. 601-612) (RFA) and 
Executive Order 13272 (Consideration of Small Entities in Agency 
Rulemaking) requires a review of proposed and final rules to assess 
their impacts on small entities. An agency must prepare an initial 
regulatory flexibility analysis unless it determines and certifies that 
a rule, if promulgated, would not have a significant impact on a 
substantial number of small entities.
    Under the RFA, 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.
    This proposed rule would create cost savings for industry because 
we estimate fewer equivalency requests to be submitted to the Coast 
Guard. We expect equivalency requests to be submitted by owners or 
operators of new U.S.-flagged vessels who may have questions about 
standards that are not in 46 CFR subchapter J. Over a 5-year period 
from 2014-2018, we found 1,051 new U.S.-flagged vessels entered 
service, or an average of approximately 210 annually during this 
period. We found that 157 companies owned the 1,051 vessels.
    Using the publicly-available online database ``ReferenceUSAgov'' 
(in addition to individual online searches of companies) to search for 
company-specific information such as annual revenues and number of 
employees, we found revenue or employee information on 91 of the 157 
companies, or approximately 58 percent.\11\ Using the Small Business 
Administration's ``Table of Size Standards'' and the North American 
Industry Classification System codes listed in the table, we found 58 
of the 91 companies to be small entities.\12\ We found the other 33 
companies to be not small.\13\ We did not find information on the 
remaining 66 companies; therefore, we assumed these companies to be 
small entities for a total of 124 small entities out of 157 companies, 
or approximately 79 percent.

    \12\ The Coast Guard was unable to find revenue information for 
two of these small entities.
    \13\ https://www.sba.gov/document/support--table-size-standards.
---------------------------------------------------------------------------

    We analyzed the potential economic impacts of this proposed rule on 
small entities and found that each small entity, who no longer submits 
an equivalency request, would save approximately $2,848 annually. We 
estimate an 80 percent reduction in the number of equivalency requests 
(from 10 to 2 annually) industry would submit to the Coast Guard with 
this proposed rule, given this information, the Coast Guard certifies 
under 5 U.S.C. 605(b) that this proposed rule would not have a 
significant economic impact on a substantial number of small entities. 
For any small entity that does not submit an equivalency request, they 
would not be impacted by any cost or cost savings.
    If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this proposed rule 
would have a significant economic impact on it, please submit a comment 
to the docket at the address under ADDRESSES. In your comment, explain 
why you think it qualifies and how and to what degree this proposed 
rule would economically affect it.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996, Public Law 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 rulemaking. 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 the person in the 
FOR FURTHER INFORMATION CONTACT section of this proposed rule. The 
Coast Guard will not retaliate against small entities that question or 
complain about this proposed 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

    The Paperwork Reduction Act of 1995, 44 U.S.C. 3501-3520, requires 
that the Coast Guard consider the impact of paperwork and other 
information collection burdens imposed on the public. The Coast Guard 
has determined that there would be no new requirement for the 
collection of information associated with proposed rule because we 
estimate that we would receive less than 10 equivalency requests 
annually from the public.

E. Federalism

    A rule has implications for federalism under Executive Order 13132 
(Federalism) if it has a substantial direct effect on States, on the 
relationship between the National Government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government. We have analyzed this proposed rule under Executive Order 
13132 and have determined that it is consistent with the fundamental 
federalism principles and preemption requirements described in 
Executive Order 13132. Our analysis follows.
    It is well settled that States may not regulate in categories 
reserved for regulation by the Coast Guard. It is also well settled 
that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 
8101 (design, construction, alteration, repair, maintenance, operation, 
equipping, personnel qualification, and manning of vessels), 43 U.S.C. 
1333, 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 Supreme Court's 
decision in United States v. Locke and Intertanko v. Locke, 529 U.S. 
89, 120 S.Ct. 1135 (2000). This proposed update to electrical 
engineering standards for vessels is issued under the authority in 46 
U.S.C. 3306(a)(1) which authorizes the Secretary to prescribe 
regulations for the design, construction, alteration, repair, and 
operation of vessels subject to inspection, including equipment, 
appliances, propulsion machinery, auxiliary machinery, boilers, unfired 
pressure vessels, piping, and electric installations. Therefore, 
because the States may not regulate within these

[[Page 21470]]

categories, this rule is consistent with the fundamental federalism 
principles and preemption requirements described in Executive Order 
13132.
    While it is well settled that States may not regulate in categories 
in which Congress intended the Coast Guard to be the sole source of a 
vessel's obligations, the Coast Guard recognizes the key role that 
State and local governments may have in making regulatory 
determinations. Additionally, for rules with federalism implications 
and preemptive effect, Executive Order 13132 specifically directs 
agencies to consult with State and local governments during the 
rulemaking process. If you believe this rule has implications for 
federalism under Executive Order 13132, please contact the person 
listed in the FOR FURTHER INFORMATION section of this preamble.

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 million (adjusted for 
inflation) or more in any one year. Though this proposed rule would not 
result in such an expenditure, we do discuss the effects of this 
proposed 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 
(Governmental 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, 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 proposed 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.

L. Technical Standards

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

M. Environment

    This action is one of a category of actions that do not 
individually or cumulatively have a significant effect on the human 
environment. A preliminary Record of Environmental Consideration 
supporting this determination is available in the docket. For 
instructions on locating the docket, see the ADDRESSES section of this 
preamble. This proposed rule would be categorically excluded under 
paragraph L57 of Appendix A, Table 1 of DHS Instruction Manual 023-01-
001-01, Rev. 01. Paragraph L57 pertains to regulations concerning 
manning, documentation, admeasurement, inspection, and equipping of 
vessels.
    This proposed rule involves incorporating by reference several 
updated electrical engineering standards along with removing several 
outdated or unnecessarily prescriptive electrical engineering 
regulations. We seek any comments or information that may lead to the 
discovery of a significant environmental impact from this proposed 
rule.

    (1) From the aggregate contribution of all generators that can 
simultaneously operate in parallel;
    (2) From the largest probable motor load; and
    (3) With a three-phase fault on the load terminals of the 
protective device.
    (b) The calculated currents must be used to select suitably rated 
equipment and to allow the selection and setting of protective devices.


Sec.  111.51-3  Short-circuit calculations for systems below 1500

    The following short-circuit assumptions must be made for a system 
with an aggregate generating capacity below 1500 kilowatts, unless 
detailed computations in accordance with Sec.  111.51-4 are submitted:
    (a) The maximum short-circuit current of a direct current system 
must be assumed to be 10 times the aggregate normal rated generator 
currents plus 6 times the aggregate normal rated currents of all motors 
that may be in operation.
    (b) The maximum asymmetrical short-circuit current for an 
alternating current system must be assumed to be 10 times the aggregate 
normal rated generator currents plus 4 times the aggregate normal rated 
currents of all motors that may be in operation.
    (c) The average asymmetrical short circuit current for an 
alternating-current system must be assumed to be 8\1/2\ times the

    (a) The coordination of overcurrent protective devices must be 
demonstrated for all potential plant configurations.
    (b) Protective relays and overcurrent protective devices must be 
installed so that:
    (1) A short-circuit on a circuit that is not vital to the 
propulsion, control, or safety of the vessel does not trip equipment 
that is vital; and
    (2) A short-circuit on a circuit that is vital to the propulsion, 
control, or safety of the vessel is cleared only by the protective 
device that is closest to the point of the short-circuit.

    (a) The fuel oil tank for the emergency generator prime mover must 
be appropriately sized and provided with a level alarm, which is to be 
set to alarm at a level where there is sufficient fuel oil capacity for 
the emergency services for the period of time required by Sec.  112.05-
5(a).
    (b) The emergency generator prime mover is to be rated for 
continuous service.
    (c) The prime mover is to be fitted with alarms, displays and 
automatic shutdown arrangements that meet ABS Marine Vessel Rules, 
section 4-8-2/5.19 Table 2, except that for fuel oil tank low-level 
alarm, in paragraph (a) of this section is to apply instead. The 
displays and alarms are to be provided in the centralized control 
station. Monitoring at the engineers' quarters must meet ABS Marine 
Vessel Rules, section 4-9-6/19.
    (d) The emergency generator room is to be fitted with fire 
detectors. Where the emergency generator is located in a space 
separated from the emergency switchboard, fire detectors are to be 
located in each space. The fire detection and alarm system must meet 
the requirements of 46 CFR subpart 113.10.
    (e) The power supply circuits, including control and monitoring

[[Page 21487]]

circuits, for the use of an emergency generator in port are to be so 
arranged and protected that any electrical fault, except for the 
emergency generator and the emergency switchboard, will not affect the 
operation of the main and emergency services.
    (f) Means are to be provided to readily change over to emergency 
operation.
    (g) The generator is to be safeguarded against overload by 
automatically shedding such other loads so that the supply to the 
required emergency loads is always available.
    (h) Operational instructions such as that on the fuel oil tank 
level, harbor/seagoing mode changeover arrangements, etc. are to be 
provided on board. Before the vessel is under way, all valves, 
switches, etc., are to be in the positions for the intended mode of 
operation of the emergency generator and the emergency switchboard. 
Such instructions are to be distinctly posted at the emergency 
generator room. Planned maintenance is to be carried out only while in 
port.
