II. Executive Summary

    Subchapter J of title 46 of the Code of Federal Regulations (CFR) 
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. On April 22, 2021, the Coast Guard 
published a notice of proposed rulemaking (NPRM) that contains a 
detailed description of the background and proposed changes. (86 FR 
21440).
    This final rule updates prior incorporations by reference in 46 CFR 
110.10-1 and all of the sections in subchapter J that reference the 
updated IBR standards, adds a limited number of alternative standards, 
and eliminates outdated or unnecessarily prescriptive regulations in 
subchapter J. More specifically, this rule incorporates more recent 
editions of many standards, incorporates by reference additional 
standards for certain topics, and removes 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, this rule implements the following four changes to 
subchapter J.
    First, this rule eliminates 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 continue to be required to 
meet standards of the American Bureau of Shipping (ABS) Steel Vessel 
Rules.
    Second, this rule simplifies 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

[[Page 16311]]

Guard's Alternate Compliance Program (ACP).
    Third, for classifications of hazardous locations in subpart 
111.105, this rule adds 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 rule amends 46 CFR subpart 112.05 to allow the use of 
an emergency generator in port. This optional capability to use 
emergency generators in port is 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 changes 
and the affected sections.

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

III. Basis, Purpose, and Regulatory History

    The legal basis of this rule is section 1333(d) of Title 43, United 
States Code (U.S.C.), sections 3306 and 3703 of Title 46 U.S.C., and 
Department of Homeland Security (DHS) Delegation No. 00170.1, Revision 
No. 01.2. 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. The provisions of 46 U.S.C. 
3306(a)(1) authorize 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 provide for navigation and vessel safety and 
protect against hazards to life, property, and the marine environment 
by regulating vessel construction, alteration, repair, maintenance, 
operation, and equipping. DHS Delegation No. 00170.1, Revision No. 
01.2, paragraph (II)(92)(b), delegates these authorities to the Coast 
Guard.
    The purpose of this rule is to update the standards 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's (OMB) Circular A-119 states agencies should undertake a 
review of the standards

[[Page 16312]]

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 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.
    On April 22, 2021, the Coast Guard published a NPRM titled ``Update 
to Electrical Engineering Regulations'' (86 FR 21440) requesting 
comments on the proposed changes implemented by this final rule, 
including several updates to the standards incorporated by reference. A 
detailed description of the background and proposed changes are 
available in that NPRM. See 86 FR at 21442-60.

IV. Discussion of Comments and Changes

    During the comment period for the April 22, 2021 NPRM (86 FR 
21440), which ended on July 21, 2021, we received 15 comments. Several 
commenters expressed their support for the Coast Guard updating the 
standards incorporated by reference to newer editions and some 
confirmed they use them in current practice. The comments also offered 
us feedback on specific changes to the electrical engineering 
requirements and standards we proposed to incorporate by reference. The 
comments can be viewed in the docket following the instructions in the 
ADDRESSES section of this preamble. We summarize the comments and our 
responses, starting with general comments and then responding in order 
of relevant CFR section. Within each CFR section, we describe any 
changes to the final rule regulatory text from what was proposed in the 
NPRM.

General

    A commenter submitted an editorial comment on the list of 
abbreviations in Section II for ``MOU.'' In this final rule, MOU is now 
correctly defined as Mobile Offshore Unit.
    A commenter requested we update 33 CFR subchapter N to clarify the 
application of this rulemaking to Outer Continental Shelf (OCS) 
facilities and stated that, at a minimum, the Coast Guard should update 
33 CFR 143.120 to establish the date on which the proposed rule would 
apply to a new floating OCS facility. Where subchapter N requires 
compliance with subchapter J, the date of applicability for vessels and 
facilities will begin 30 days after publication of this final rule, in 
accordance with the revised Sec.  110.01-1(b). The updated requirements 
and standards in subchapter J apply to electrical installations 
contracted for after the effective date of the final rule.
    The commenter also noted that the Bureau of Safety and 
Environmental Enforcement (BSEE) in the Department of the Interior is 
working on a regulatory update to incorporate more modern industry 
standards and recommended the Coast Guard engage with BSEE to ensure 
that both regulatory efforts are aligned, as the agencies propose to 
incorporate different revisions of the same industry standard in at 
least two cases. The Coast Guard and BSEE have a shared mission of 
ensuring safety on the OCS. We work closely together to ensure our 
requirements are not in conflict with each other, even if we use 
different revisions of the same standard. Because this final rule is 
not adding any new requirements for vessel owners and operators, it 
will not cause any conflicts with BSEE requirements. Any specific 
concerns can be addressed to either the Coast Guard's Eighth District 
Outer Continental Shelf Division staff (website: https://www.atlanticarea.uscg.mil/D8/OCS/) or the Coast Guard's Outer 
Continental Shelf National Center of Expertise (OCSNCOE) (website: 
https://www.dco.uscg.mil/OCSNCOE/).
    Two commenters requested that we clarify the applicability of 
subchapter J to Floating Production Units (FPUs), as the Coast Guard 
Office of Design and Engineering Standards' (CG-ENG) relevant policy 
letter, CG-ENG Policy Letter 01-13,\1\ only applies to classed FPUs 
rather than all FPUs in service. Similarly, a commenter requested that 
the Coast Guard clarify the applicability of subchapter J to floating 
OCS facilities, as the application of the subchapter has led to many 
requests for equivalencies and alternatives for a class of 
installations that may not technically be vessels. The comment stated 
that the Coast Guard should act on the National Offshore Safety 
Advisory Committee's recommendation that the Coast Guard issue a task 
statement to evaluate the suitability of subchapters F and J for 
floating OCS facilities. These requests are outside the scope of this 
rulemaking, which focuses on updating the electrical engineering 
standards set out in subchapter J but not further amending the 
applicability of subchapter J. Nevertheless, we have shared them with 
the appropriate Coast Guard offices. We encourage questions regarding 
the applicable regulations for floating OCS facilities to be sent to 
either the Coast Guard's Eighth District Outer Continental Shelf 
Division Staff (website: https://www.atlanticarea.uscg.mil/D8/OCS/) or 
OCSNCOE (website: https://www.dco.uscg.mil/OCSNCOE/).

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

Subpart 110.01--Applicability

Sec.  110.01-1 General
    We received requests for information on the implementation dates 
for the revised regulations. In response and to provide greater clarity 
for the public, this final rule includes an amendment to Sec.  110.01-
1(b) that explains the effective date of the requirements in this rule. 
The requirements implemented in this final rule will be effective 30 
days after the publication of this final rule. Paragraph (b) will also 
clarify that subchapter J applies only to electrical installations 
contracted for after the effective date of this final rule. Existing 
paragraph (c) of this section will continue to allow a vessel's 
electrical installations to meet the subchapter J regulations in place 
when those systems were initially installed. According to existing 46 
CFR 110.01-3(a), repairs and replacements in kind must comply with 
either the regulations in this subchapter or those in effect when the 
vessel was built. Per Sec.  110.01-3(b), alterations and modifications, 
such as re-engining, re-powering, upgrading of the main propulsion 
control system, or replacing extensive amounts of cabling, must comply 
with the regulations in this subchapter, including updates implemented 
by this final rule. Per existing Sec.  110.01-1(c), all electrical 
systems installed or under Coast Guard review prior to this date may 
meet the regulations in place at the time of installation or submittal 
to the Coast Guard.

Subpart 110.10--Reference Specifications, Standards, and Codes

Sec.  110.10-1 Incorporation by Reference
    We received the following comments in regard to our update of the 
technical standards incorporated by reference in subchapter J in Sec.  
110.10-1.
    Several commenters suggested incorporating by reference newer 
editions than we had proposed to incorporate in Sec.  110.10-1. Because 
of the frequent release of new editions, and the time necessary to 
evaluate them and propose their incorporation, it is often impractical 
to incorporate standards or new editions that publish after we issue 
our NPRM. Instead, the Coast Guard considered whether the standards 
proposed in the NPRM are still

[[Page 16313]]

sufficient and relevant to electrical engineering practices at the time 
of this final rule, even if a newer edition is available. We determined 
that the editions proposed in the NPRM are still sufficient and 
relevant.
    Several commenters requested incorporating by reference different 
standards than are referenced in Sec.  110.10-1 or proposed in the 
NPRM. The suggestions included standards and codes for alternative 
propulsion fuels; inspection, maintenance, and repair of equipment in 
hazardous locations; and hazardous location equipment directories or 
dossiers. These topics are not currently addressed in subchapter J. 
Including them at this stage would impose new regulatory requirements 
on vessels and facilities. This rule is intended to update the existing 
regulations in subchapter J and result in quantitative and qualitative 
savings for vessel owners. For this reason, standards for topics not 
currently addressed in subchapter J are outside the scope of this final 
rule. We may consider some of these standards in the future for 
incorporation by reference following a thorough technical analysis of 
the standards as well as their potential costs and benefits. Further, 
proposals for new requirements on topics not already included in 
subchapter J would be given additional public notice and opportunity 
for comment.
    Additionally, we received specific comments on the following 
standards we proposed for incorporation by reference.
    American National Standards Institute (ANSI)/UL standards: A 
commenter requested that we refer to the UL standards as ANSI/UL 
standards. In many of the regulatory text sections we do refer to such 
standards as ANSI/UL standards, but we do not do so in the IBR section, 
Sec.  110.10-1. In that IBR section, we are required to list the 
standard name exactly as it appears on the cover of the standard.
    The commenter also noted that many ANSI/UL standards related to 
hazardous locations replaced similar ISA standards, and suggested the 
UL standards should be referenced throughout the CFR. We agree with 
listing the ANSI/UL standards in addition to where we proposed to 
include the ANSI/ISA standard because of their similarities in 
requirements and options. In the NPRM we proposed to incorporate ANSI/
ISA 12.12.01 (2015). In this final rule we are also adding ANSI/ISA-
RP12.06.01 (2003) because it superseded a previously incorporated 
standard we removed, ISA RP 12.6 (1995). These two are the only ANSI/
ISA standards that will be incorporated by reference in subchapter J 
and both are active standards. Where the ANSI/ISA series of standards 
are referenced in Sec. Sec.  111.105-3(b)(2), 111.106-3(b)(2), and 
111.108-3(b)(2), this final rule adds the ANSI/UL series as an option 
in those sections as well.
    IEEE 100 (2000): A commenter noted that the Institute of Electrical 
and Electronics Engineers (IEEE) withdrew the standard IEEE 100 (2000). 
IEEE 100 (2000) is only referenced in Sec.  110.15-1 regarding 
electrical and electronic term definitions. We have decided to retain 
it in subchapter J because the definitions are still relevant. We have 
confirmed that the standard is still available for the public to 
purchase despite IEEE withdrawing it. We acknowledge that a revision to 
the standard is underway and we will consider updating references to 
this standard in the future.
    IEEE 1580 (2010): A commenter suggested we incorporate the 2018 
edition. The 2018 edition was still in the draft stage when we 
published the NPRM in April 2021, and we were not able to propose draft 
standards for incorporation by reference. The IEEE board approved the 
IEEE 1580 (2021) on November 9, 2021, and published it on March 23, 
2022, both dates after the comment period for the NPRM closed. The IEEE 
1580 (2021) standard superseded the 2010 version. IEEE 1580 provides 
recommended practice for marine cable use on shipboard and fixed or 
floating facilities, and the 2021 edition addresses changes in changes 
in technology and revisions to referenced standards since 2010. The 
Coast Guard has decided that the 2010 version is still sufficient and 
relevant for marine cables at the time of this final rule. However, the 
public can submit equivalency requests for the 2021 edition to the 
Marine Safety Center (MSC) in accordance with Sec.  110.20-1.
    IEC 60092-302:1997: A commenter noted that this standard was 
superseded by IEC 60092-303-2, Electrical installations in ships--Part 
302-2: Low voltage switchgear and controlgear assemblies--Marine power, 
published in 2019. We have decided to retain the 1997 edition until we 
can thoroughly review the 2019 edition. However, we may consider 
switchgear meeting the standards in IEC 60092-302-2:2019 under the 
equivalency provisions of Sec.  110.20-1.
    ISA RP 12.6:1995: We proposed in the NPRM to remove ISA RP 12.6 
because ISA has withdrawn it. A commenter noted that a new standard, 
ANSI/ISA RP12.06.01, has superseded ISA RP 12.6. The commenter is 
correct. Because the two standards are very similar, we are replacing 
the withdrawn ISA RP 12.6 standard with the new ANSI/ISA RP12.06.01 
standard as suggested. This final rule incorporates by reference ANSI/
ISA-RP12.06.01:2003 in Sec.  111.105-11. ANSI/ISA-RP12.06.01 is a 
recommended practice that promotes the uniform installation of 
intrinsically safe systems in hazardous (classified) locations and 
clarifies the requirements of Articles 504 and 505 of National Fire 
Protection Association (NFPA) standard NFPA 70.

Subpart 110.25--Plan Submittal

Sec.  110.25-1 Plans and Information Required for New Construction
    A commenter noted that the proposed changes to Sec.  111.105-3 
provided the option to select electrical equipment on any single vessel 
to comply with NFPA 70 Articles 500-504, or NFPA 70 Article 505, or IEC 
60092-502, based on either the Division or the Zone method of hazardous 
location classification. The commenter suggested that we amend the plan 
requirements for hazardous locations in Sec.  110.25-1 to ensure the 
classification method is indicated on the plans submitted for review. 
We agree with this suggestion and are incorporating it into this final 
rule. The extent and classification of all hazardous locations is 
already required in the existing Sec.  110.25-1(i) but clearly 
indicating the method of classification, Division or Zone, is important 
to ensure appropriate selection of equipment for the hazardous 
location. In this final rule, we amend Sec.  110.25-1(i) to require 
that the plans indicate the method of classification of the hazardous 
locations in addition to the other requirements already included in 
paragraph (i).

Subpart 111.10--Power Supply

Sec.  111.10-9 Ship's Service Supply Transformers; Two Required
    A commenter noted that our proposed revision to the note to Sec.  
111.10-09 concerning ship's service transformers appears to contradict 
the text of Sec.  111.10-09 regarding the number of transformers. We 
disagree. Section 111.10-3 requires that the shipboard power supply 
system on self-propelled vessels have at least two electric generating 
sources. The intent of Sec.  111.10-09 is to continue this requirement 
by duplicating the number of transformers that are used to supply the 
ship's service distribution system. As explained in this note, the 
intent is not to provide duplication of ship's service distribution 
system circuits after the ship's service switchboard. This is a long-
standing position that is explained in Coast Guard guidance, 
specifically

[[Page 16314]]

``Guide for Electrical Installations on Merchant Vessels and Mobile 
Offshore Units,'' dated August 14, 1989.\2\

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

Subpart 111.12--Generator Construction and Circuits

Sec.  111.12-11 Generator Protection
    Section 111.12-11(g) states that a ship's service generator and its 
switchboard must be in the same space and states that a control room 
inside the machinery casing is not considered outside the machinery 
space. Paragraphs 111.12-11(g)(1) and (2) provide two arrangements that 
the Coast Guard considers to meet this requirement. In other words, we 
consider a switchboard room within the machinery space, containing the 
overcurrent protection on the switchboard, to be satisfactory, 
regardless of whether there are centralized engineering controls or 
monitoring in that control room. This rule, which replaces a reference 
to a ``semiconductor rectifier'' with ``semiconductor converter'' in 
paragraph (g), does not substantively change these existing provisions. 
A commenter asked if a control room that is an air-conditioned 
switchboard room with generator controls on a switchboard, but without 
centralized engineering control and monitoring, is an acceptable 
control room. This question is beyond the scope of this rulemaking, but 
questions regarding compliance with Subchapter J may be submitted to 
the MSC.

Subpart 111.15--Storage Batteries and Battery Chargers: Construction 
and Installation

    Two commenters suggested we consider incorporating by reference 
IEEE 1187-2013, ``IEEE Recommended Practice for Installation Design and 
Installation of Valve-Regulated Lead Acid Batteries for Stationary 
Applications.'' The commenters noted that although FPUs are not 
stationary, they are not ocean-going vessels either. The commenters 
also noted because FPUs do not have the range of motions of a vessel, 
they use valve-regulated lead acid batteries (as governed by IEEE 1187-
2013) rather than the vented lead-acid batteries covered in the NPRM's 
updates to subchapter J. We understand the unique characteristics of 
FPUs may require additional options and guidance. Specifically, 33 CFR 
143.120(b) and CG-ENG Policy Letter 01-13 allow alternate proposals for 
floating OCS facilities. System designers may submit applications to 
the MSC demonstrating that a system using valve-regulated lead acid 
batteries, as governed by IEEE 1187-2013, provides an equivalent level 
of safety in accordance with Sec.  110.20-1. We understand this IBR 
suggestion and may consider it in a future rulemaking. Further, we find 
that we cannot include this suggestion in this final rule because, in 
order to add the standard and those additional requirements, we would 
prefer to conduct an additional analysis of alternatives and provide 
the public opportunity to review and comment on its addition.

Subpart 111.30--Switchboards

Sec.  111.30-5 Construction
    In the NPRM, we proposed replacing the existing reference to 
section 8.3 of IEEE 45-2002 in Sec.  111.30-5(a)(1) with a reference to 
section 6 of the more recent IEEE 45.7-2012. A commenter noted section 
6.3.3 of IEEE 45.7 requires a steering gear breaker trip set to not 
less than 200 percent of locked rotor current. This conflicts with 
Sec.  58.25-55(a)(2), which requires a trip set point between 175 and 
200 percent of locked rotor current. We agree that the change we 
proposed in the NPRM would present an unintended conflict with other 
existing regulations. The intent of Sec.  111.30-5 is to address 
switchboard construction, not overcurrent protection for specific 
systems, so when reviewing IEEE 45.7 we did not observe that the 
standard added a requirement for the steering gear circuit overcurrent 
protection. We did not intend the NPRM to propose a change to the 
existing requirements for steering gear circuit overcurrent protection. 
For this reason, in Sec.  111.30-5(a)(1) of this final rule, we are 
incorporating section 6 of IEEE 45.7-2012, excluding section 6.3.3.
    A commenter asked for clarification of the proposed Sec.  111.30-
5(c) regarding switchboard construction, which stated that ``[t]he 
interchangeability and compatibility of components complying with both 
IEEE and IEC cannot be assumed.'' We agree this proposed paragraph (c) 
could have caused confusion. Our intent in this paragraph was to 
discourage the mixing of acceptable standards in a manner that could 
result in a potentially unsafe switchboard. We recognize that complying 
with and enforcing this relatively vague requirement would be 
difficult, and we have accordingly deleted it in this final rule. 
Switchboards should be constructed in accordance with the standards 
incorporated by reference in subpart 111.30.
Sec.  111.30-19 Buses and Wiring
    In the NPRM, we proposed replacing the existing reference to 
section 7.10 of IEEE 45-1998 in Sec.  111.30-19(a)(1) with a reference 
to section 5.10 of the more recent IEEE 45.7-2012. A commenter noted 
section 5.10 of IEEE 45.7-2012 appears to have less strict requirements 
for generator bus sizing and could be interpreted to not require sizing 
to support overload operation of the generator for a sustained period. 
We disagree. The requirements are very similar, and IEEE 45.7-2012 
reflects the latest guidance on bus sizing.
Sec.  111.30-25 Alternating-Current Ship's Service Switchboards
    A commenter suggested that the generator field rheostat (manual 
voltage controller) currently required by Sec.  111.30-25(c)(1) was of 
limited value and is not required by other regulatory bodies. We 
understand this suggestion and may consider it in a future rulemaking. 
In order to remove the requirement, we would prefer to conduct an 
additional analysis of alternatives and provide the public opportunity 
to review and comment on its removal. In the meantime, however, system 
designers may submit switchboards with alternative instrumentation that 
provides an equivalent level of safety to the MSC in accordance with 
Sec.  110.20-1.

Subpart 111.33--Power Semiconductor Converter Systems

    In the NPRM, we proposed changing the heading of subpart 111.33 
from Power Semiconductor Rectifier Systems to Power Semiconductor 
Converter Systems and changing references to rectifiers to converters. 
This proposed change aligned with general industry practice of using 
the term converter as it is more general than rectifier. This subpart 
applies to rectifiers (alternating current (AC) to direct current 
(DC)), inverters (DC to AC), and other power converters. Additionally, 
in the NPRM we proposed updating the standards incorporated by 
reference in this subpart to more recent editions. A commenter noted 
that 4.31.19.12 of IEEE 45.2-2011, which would replace 10.20.12 of IEEE 
45-2002, covers rectifiers. The commenter is correct in this regard. 
However, 4.31.19.12 of IEEE 45.2-2011 provides the required nameplate 
data, and the Coast Guard determined the requirements of this section 
are also generally applicable to

[[Page 16315]]

any power semiconductor converter system.
    In addition, in the NPRM, we proposed replacing references 
throughout subpart J to ``semiconductor rectifier (SCR)'' with 
references to ``semiconductor converter''. However, upon further review 
following the NPRM's publication, we realized that some instances of 
this amendment were inadvertently not included in the amendatory 
language for the NPRM. We have updated the amendatory language in this 
final rule to include these missed instances of ``converter'' in this 
final rule at Sec. Sec.  111.33-1 and 111.33-3(b).

Subpart 111.40--Panelboards

Sec.  111.40-1 Panelboard Standard
    A commenter noted Section 9.10 of IEEE 45.1, proposed for 
incorporation by reference in the NPRM, includes multiple sub-sections 
but only subsection 9.10.1 is directly applicable to panelboards. The 
commenter suggested updating the reference to only include this 
subsection. We agree, and in the interest of greater precision we 
revise Sec.  111.40-1 in this rule to only reference subsection 9.10.1.

Subpart 111.50--Overcurrent Protection

Sec.  111.50-3 Protection of Conductors
    A commenter noted that currently neither Sec.  111.50-3 nor Sec.  
111.20-15 clearly addresses NFPA 70--National Electric Code (NEC) 
requirements for transformer secondary conductor protection and 
suggested that Sec.  111.50-3 should include or cite to NEC 
240.21(C)(1) requirements. NEC 240.21(C)(1) explicitly states that 
primary overcurrent protection is insufficient to protect secondary 
conductors of delta-wye transformers. In the NPRM, we did not propose 
substantive changes to these two sections beyond incorporating the more 
recent editions of the standards. Adding the requirements at NEC 
240.21(C)(1) to Sec.  111.50-3 would require additional analysis and 
opportunity for the public to review and comment. Nevertheless, we may 
consider incorporating NEC Article 240, which provides guidance for 
transformer conductor overcurrent protection, in Sec.  111.50-3 in the 
future.
    A commenter also said that neither Sec.  111.50-3 nor Sec.  58.25 
currently address DC steering gear motors. The commenter also said that 
both Sec. Sec.  111.50-3 and 58.25 are silent on the use of fuses for 
overcurrent protection in these systems. The commenter suggested that 
we remove the cross-reference to 46 CFR 58.25 and revise Sec.  111.50-3 
to align with ABS SVR 4-8-2/9.17.5 standards on DC steering gear motors 
and prohibiting fuses. We disagree with the suggested change. Paragraph 
58.25-55(a)(1) specifically requires DC steering gear motors to be 
protected from overcurrent by a circuit breaker at the switchboard. 
This section does not list fuses as an acceptable means of overcurrent 
protection. Vessel owners and operators must ensure DC steering gear 
motors are protected from overcurrent by circuit breakers unless an 
equivalent arrangement is approved by the MSC in accordance with Sec.  
110.20-1. We did not propose substantive changes to these two sections 
in the NPRM beyond incorporating the more recent editions of the 
standards already incorporated by reference in Sec.  111.50-3. However, 
we will consider updating our steering gear motor regulations in the 
future following a review of the latest advances in steering gear power 
and control systems.

Subpart 111.51--Coordination of Overcurrent Protection Devices

Sec. Sec.  111.51-1 Purpose and 111.51-5 Protection of Vital Equipment
    In the NPRM, we proposed to revise Sec.  111.51-1 to set out a 
broad introductory discussion of the requirements for coordination of 
overcurrent protection devices that is based on the recommendations in 
IEC 60092-202:2016 and not substantively different from the existing 
Sec.  111.51-1 that it replaced. A commenter noted the term 
``continuity of service'' as used in the proposed revisions to Sec.  
111.51-1, as well as in the current text of Sec.  111.51-1, is not 
defined and could be interpreted in a number of ways. Additionally, the 
same commenter also recommended editing Sec.  111.51-5(b)(2) to allow 
for cases where multiple protective devices are directly in series due 
to the arrangement of the power system and vendor equipment supply or 
requirements for disconnecting device. Alternatively, they suggested we 
define that a protective device refers to a set of one or more 
protective devices which protect the same segment of the electrical 
system. The commenter was concerned the section could be interpreted to 
require explicit coordination between protective devices within the 
same feeder or branch circuit.
    It is not the intent of this final rule to substantively alter our 
existing regulations for coordination of overcurrent protection 
devices. Continuity of service is defined in IEC 60092-202:2016 as a 
``condition where, after a fault in a circuit has been cleared, the 
supply to the healthy circuits is re-established.'' More importantly, 
the goal of overcurrent protection coordination is to minimize the 
impact of short circuits on vital equipment as explained in Sec. Sec.  
111.51-1 and 111.51-5. If multiple protective devices are in series, it 
is incumbent on the system designer to demonstrate the devices satisfy 
the intent of overcurrent protection coordination. Additionally, 
proposing a unique definition for protective devices is not a preferred 
option where the definition is widely used and defined by a standard. 
We encourage the use of established industry standards and definitions. 
If there are any vessel or system specific arrangements being proposed 
for Coast Guard certificated vessels, their equivalency with this 
subpart can be demonstrated to the MSC in accordance with Sec.  110.20-
1. We made no changes from the proposed rule in Sec.  111.51-5.

Subpart 111.60--Wiring Materials and Methods

Sec.  111.60-3 Cable Application (Existing)
    In the NPRM, we proposed to delete this section because it is 
unnecessarily prescriptive. In its place, we proposed that regulated 
entities would consult the current and proposed cable construction 
standards in proposed new Sec.  111.60-1 for the application of 
specific types of cable. A commenter expressed concern that cable for 
specialized applications, such as scientific research instruments and 
passenger ferry Wi-Fi networks, is sometimes not available or cost-
prohibitive to meet the fire test requirements. The commenter 
recommended retaining Sec.  111.60-3 largely as written. Based on our 
research for available products, the Coast Guard has determined that 
common types of cables that comply with the standards in Sec.  111.60-1 
are available and provide the safest option for U.S. vessels. 
Additionally, our research indicates the cost will be comparable to all 
other cable suitable for marine applications. Accordingly, this final 
rule retains the amendment from the NPRM to remove Sec.  111.60-3. We 
will consider other cable on a case-by-case basis in accordance with 
the equivalency provisions of Sec.  110.20-1.
Sec.  111.60-4 Minimum Cable Conductor Size
    A commenter noted we did not propose changing the required minimum 
conductor size in this section of 0.82 square millimeters (mm\2\) and 
2.1 mm\2\ for control and power cable, respectively. The commenter 
explained that vessels inspected under the ACP

[[Page 16316]]

have a lesser conductor size requirement. For example, ABS MVR 4-8-2/
7.7.2 allows smaller minimum conductor sizes of 0.5 mm\2\ and 1.5 mm\2\ 
for control and power cable respectively. (The metric dimensions given 
in this section are metric conversions of the standard American Wire 
Gauge sizes rather than standard metric wire sizes suggested by this 
commenter and used in the ABS rule.) The commenter recommended we 
decrease the metric size requirements to match the requirements 
applicable to ACP vessels because they believed doing so would 
eliminate the need to excessively oversize metric cable to meet rules 
that are currently written to align with common AWG sizes. Vessels 
enrolled in the ACP comply with a comprehensive set of engineering 
standards and an inspection regime that collectively provide a level of 
safety equivalent to complying solely with the regulations in 46 CFR 
even though the requirements are not identical. As the commenter noted, 
we did not propose substantive changes to this section in the NPRM and 
do not intend to change it in the final rule. Allowing smaller minimum 
conductor sizes on all vessels regulated by subchapter J is a less 
stringent requirement that we may consider in the future following 
additional analysis and opportunity for public comment. Presently, the 
metric conductor size requirements in this section are still considered 
reasonable and safe, and we made no additional changes based on this 
recommendation.
Sec.  111.60-6 Fiber Optic Cable (Existing)
    In the NPRM, we proposed to remove current Sec.  111.60-6 because 
fiber optic cable that complies with Sec.  111.60-1 is now available. A 
commenter contended that such fiber optic cable is not readily 
available. We agree that it may be difficult to find fiber optic cable 
to meet the standards in Sec.  111.60-1 and have decided to forgo the 
proposed change to remove Sec. Sec.  111.60-2 and 111.60-6. This final 
rule does not remove existing Sec. Sec.  111.60-2 and 111.60-6, or the 
cross references to Sec. Sec.  111.60-2 and 111.60-6 within the 
applicable list of standards incorporated by reference in Sec. Sec.  
110.10-1(j)(14), 110.10-1(q)(23), 110.10-1(k)(34), 110.10-1(k)(35), and 
110.10-1(j)(13), where they were already included. However, in this 
final rule we have updated the standards mentioned within Sec. Sec.  
111.60-2 and 111.60-6 to conform with updates to standards incorporated 
by reference within this subchapter.
Sec.  111.60-11 Wire
    A commenter noted the reference to Section 5.7 of IEEE 45.8-2016 in 
Sec.  111.60-11 and pointed out that this section does not address 
wire. We agree and have removed the reference to Section 5.7 of IEEE 
45.8 from this section because it is not related to the topic of Sec.  
111.60-11. The commenter also suggested that wire constructed to a 
recognized commercial standard or military specification MIL-W-16878 or 
MIL-W-22759, with particular attention to the effects of vibration, 
moisture, ambient temperature, and other adverse conditions such as 
contaminants and oils that may be present should be acceptable. We 
agree in principle. Section 111.60-11(c) provides that wire must the 
requirements set out in one of three standards for wire and concludes 
with ``or equivalent standard.'' System designers choosing an 
alternative standard they believe equivalent, such as that described by 
the commenter, should discuss it with the MSC. There are too many 
relevant standards to incorporate them all. Instead, we have decided to 
offer three standards as guidance for acceptable wire requirements. We 
will consider equivalency requests in addition to the standards we 
incorporate by reference.

Subpart 111.70--Motor Circuits, Controllers, and Protection

Sec.  111.70-3 Motor Controllers and Motor-Control Centers
    A commenter noted that the proposed regulatory text in the NPRM 
implied that we were making changes to Sec. Sec.  111.70-3(c)(2) and 
(d)(1)(v) but the proposed regulatory text as presented in the NPRM was 
unchanged from existing regulatory text. This observation is correct. 
We erroneously included these sections in the NPRM's amendatory 
instructions, but we did not actually propose any changes. No changes 
were intended. This final rule does not include any amendments to the 
regulatory text at Sec. Sec.  111.70-3(c)(2) and (d)(1)(v).

Subpart 111.75--Lighting Circuits and Protection

Sec.  111.75-17 Navigation Lights
    In the NPRM, we proposed incorporating EN 14744 in Sec.  111.75-17 
as an additional alternative standard for navigation lights. Currently, 
UL 1104 is the only standard incorporated by reference in Sec.  111.75-
17. One commenter suggested that, since UL 1104 is no longer supported 
by UL and does not address electromagnetic interference or light-
emitting diode (LED) light lifecycle degradation, it should be removed 
from this section and EN 14744 should be adopted as the sole standard 
for all navigation lights, including AC- and DC-powered lights, 
incandescent and non-incandescent lights, lights on all vessel types 
and sizes, and lights on inspected and non-inspected vessels.
    We disagree with the suggestion to remove UL 1104. Several years 
ago, UL transferred responsibility for the maintenance of UL 1104 to 
the American Boat and Yacht Council (ABYC). Prior to this rulemaking, 
UL 1104 was the only standard for the construction and testing of 
navigation lights incorporated by reference in subchapter J, and it is 
currently being used by several navigation light manufacturers. Lights 
manufactured and certified to UL 1104 meet the current luminous 
intensity and colorimetric requirements of the International 
Regulations for Preventing Collisions at Sea, 1972 (1972 COLREGS). 
Additionally, the environmental performance requirements contained in 
UL 1104 are similar in intent to those in EN 14744. For these reasons, 
we are not removing UL 1104 at this time.
    Additionally, we cannot incorporate by reference EN 14744 for all 
light and vessel types as suggested. The scope of this rule is limited 
to subchapter J. The navigation light requirements in subchapter J 
generally apply to larger, inspected commercial vessels. The 
requirements for navigation lights on certain smaller, inspected 
commercial vessels, uninspected commercial vessels, and recreational 
vessels are contained in other subparts of the CFR. We did not propose 
amendments to those subparts in the NPRM, and because of this we cannot 
incorporate by reference EN 14744 for all light and vessel types.
    Since UL transferred UL 1104 to ABYC we have worked with ABYC and 
other navigation light stakeholders to develop an updated navigation 
light standard to replace UL 1104. This standard, ABYC C-5, 
Construction and Testing of Electric Navigation Lights, published in 
July 2021, too late for inclusion in the NPRM and after the NPRM 
comment period closed. ABYC C-5 is applicable to all light and vessel 
types and addresses both electromagnetic interference and LED light 
lifecycle degradation. We may address the incorporation by reference of 
ABYC C-5, a broader incorporation by reference of EN 14744, other 
potential navigation light standards, and navigation light requirements 
for all vessel types in a future, broader, Coast Guard proposal.

[[Page 16317]]

Subpart 111.83--Shore Connection Boxes

Sec.  111.83-7 High Voltage Shore Connection
    A commenter noted that proposed new Sec.  111.83-7 only applies the 
requirements of IEC/IEEE 80005-1:2019 to vessels required by law to 
have high voltage shore connections (HVSCs), and recommended removing 
that limitation. The Coast Guard agrees the proposed limitation to only 
vessels that were required by state or local law to connect to HVSC 
would have created unnecessary confusion. This section does not require 
compliance with IEC/IEEE 80005-1:2019; it is a recommendation for best 
practices and additional safety. For vessels that connect to electrical 
shore power using an HVSC, we recommend complying with IEC/IEEE 80005-
1:2019 regardless of whether it is required by a state or local 
jurisdiction. For this reason, we have removed the limitation that 
Sec.  111.83-7 would only apply to vessels required by law to have 
shore power and instead provide this section as a recommended standard 
for all vessels that use an HVSC.
    Another commenter requested that the ABS Guide for High Voltage 
Shore Connection be considered for incorporation by reference as an 
alternative standard for HVSCs. We have not incorporated this guide. 
IEC/IEEE 80005-1:2019, which is incorporated by reference in the new 
Sec.  111.83-7, is an international voluntary consensus standard that 
provides an acceptable baseline recommendation, while the ABS Guide for 
High Voltage Shore Connection is a classification society guide. 
Although the ABS Guide for High Voltage Shore Connection may be a 
satisfactory alternative for consideration in an equivalency request, 
it is not necessary to list a classification society guide in the 
regulations when an international voluntary consensus standard is 
available. The National Technology Transfer and Advancement Act of 1995 
(15 U.S.C. 272 note) directs Federal agencies to use voluntary 
consensus standards in their regulatory activities unless doing so 
would be inconsistent with applicable law or otherwise impractical.

Subpart 111.99--Fire Door Holding and Release Systems

Sec.  111.99-5 General
    The NPRM proposed updating the existing citation in Sec.  111.99-5 
to reflect a more current edition of the International Convention for 
Safety of Life at Sea, 1974 (SOLAS), Sixth edition. A commenter noted 
that SOLAS II-2/9.4.1.1.5 includes a number of paragraphs that include 
requirements for safe functioning of the fire door release system. The 
commenter suggested that we expand Sec.  111.99-5 to include these 
additional paragraphs in II-2/9.4.1.1.5 beyond that which was 
referenced in the NPRM. We understand that SOLAS contains additional 
requirements for fire doors. Vessels that comply with SOLAS must meet 
these requirements, but requiring all vessels that must comply with 
Subchapter J's requirements meet these standards would place regulatory 
requirements on these vessels without providing appropriate opportunity 
for public notice and comment. Accordingly, we did not incorporate this 
suggestion at this time.

Subpart 111.105--Hazardous Locations

    One commenter suggested we remove the Division system for 
classification of hazardous locations from subchapter J. The commenter 
said that compliance would be simpler if only the Zone system was 
accepted. We disagree. This is an established system used extensively 
in North America and removing the Division system would adversely 
affect many equipment manufacturers.
    Another commenter requested we incorporate by reference American 
Petroleum Institute (API) standards API RP 14FZ and API RP 500, and 
IEEE 1187-2013. As we discussed in regard to a comment on subpart 
111.15, we are not inclined to incorporate IEEE 1187 because it 
contains additional requirements beyond what we believe necessary to 
incorporate at this time. API RP 14FZ and API RP 500 are already 
incorporated or will be incorporated in a very limited scope, which we 
have determined to be a reasonable level at which to require these 
standards.
Sec.  111.105-3 General Requirements and System Integrity
    The intent of Sec.  111.105-3 is to ensure all electrical equipment 
installed in a hazardous location is appropriate for the location. One 
commenter suggested that acceptable electrical components may be 
combined in a manner that may produce an assembly that can ignite a 
hazardous atmosphere and that this may not be caught in after-
installation inspections. The commenter suggested several standards to 
address this concern, such as ANSI/UL 698A, IEC TS 60079-46, ANSI/UL 
508A, and UL 2011. Additionally, the commenter suggested that this rule 
address the importance of assembly verification throughout the 
equipment lifecycle from design to installation. Assembly verification 
throughout the process is an important issue for system designers, but 
it is outside the scope of this rulemaking. Applicants must include 
assemblies of electrical equipment in plans and installation details in 
their request for Coast Guard review in accordance with Sec. Sec.  
110.25-1(i) and (j). The Coast Guard then reviews the plans and 
installation details to ensure safe assembly in accordance with these 
standards.
    Several commenters requested clarification of the phrase ``and not 
in combination in a manner that will compromise system integrity or 
safety,'' proposed in the NPRM for new Sec.  111.105-3(c). 
Additionally, commenters suggested that we reorganize Sec.  111.105-3 
to better separate equipment selection standards and installation 
requirements. Since its initial adoption in 1996, our intentions in 
Sec.  111.105-5 (which we had proposed to move into Sec.  111.105-3) 
have been to ensure that proper and safe equipment is used in hazardous 
locations and to allow safe combinations of equipment complying with 
either NFPA 70 (Division system) or the IEC 60079 series of standards 
(Zone system).\3\ The phrase in question, located in Sec.  111.105-3(c) 
in this final rule, ensures such systems are carefully designed because 
the methods of classification of hazardous locations can differ. When a 
location is subject to two classification systems, it may have two 
different classifications. For example, a specific cargo oil tank may 
be classified as a Class I, Division 1, location under one system and 
Zone 0 under the other. In this example, electrical equipment approved 
for Class I, Division 1 (intrinsically safe) or approved for Zone 0 
(ia) may be installed in the cargo tank.
---------------------------------------------------------------------------

    \3\ ``Electrical Engineering Requirements for Merchant Vessels'' 
interim rule (61 FR 28284, June 4, 1996).
---------------------------------------------------------------------------

    In the NPRM we proposed to combine Sec. Sec.  111.105-3 and 
111.105-5 into Sec.  111.105-3 to be consistent with Sec. Sec.  
111.106-3 and 111.108-3. This created confusion among commenters, and 
we have decided to revise our approach to proposed Sec.  111.105-3. 
Instead, we have renumbered the proposed Sec.  111.105-7 as Sec.  
111.105-3 and amended it to be more consistent with Sec. Sec.  111.106-
3 and 111.108-3 by adding notes after new paragraphs 111.105-3(b)(1) 
and (b)(2). This change better clarifies the appropriate guidance for 
using Zone equipment in Division-designated spaces or using Division 
equipment in Zone-designated spaces.

[[Page 16318]]

Additionally, as mentioned earlier, we will also require in Sec.  
110.25-1(i) that applicants clearly indicate the hazardous location 
method of classification, Division or Zone, in their plan submissions.
    One comment suggested that it was more appropriate to incorporate 
by reference Clause 7 rather than Clause 6 of IEC 60092-502 in Sec.  
111.105-3(b). We disagree. Clause 6 concerns the requirements of 
electrical equipment in hazardous areas while Clause 7 addresses 
installation of electrical equipment in hazardous areas. The intent of 
Sec.  111.105-3(b) is to prescribe the standards for electrical 
equipment intended for hazardous areas (locations), not specifically 
installation. This is the same as Sec.  111.108(a)(3). It was not our 
goal for the proposed modifications to Sec.  111.105 to substantively 
change the standards fundamental to equipment selection. In the 
existing regulations, in accordance with Sec.  111.108-1(b), all 
vessels could use the standards specified in 46 CFR Subpart Sec.  
111.108. Revisions to Sec.  111.105 are intended to make this clearer.
    One comment noted that for electrical installations on mobile and 
fixed offshore units the proposed requirements only reference Clause 8 
of IEC 61892-7. The commenter also noted that Clause 8 excludes 
guidance on cables and conduits and Clause 9 of IEC 61892-7 is for 
cables and wiring systems. This is correct. We intentionally did not 
reference Clause 9 for cables and wiring systems. Prior to this 
rulemaking, we previously incorporated Clause 6 of IEC 61892-7:2007. 
Clause 6 addresses electrical equipment in hazardous areas, but not 
wiring or cable systems. We proposed to incorporate by reference the 
more recent Clause 8 of IEC 61892-7:2019. Clause 8 similarly addresses 
electric equipment by referencing Clause 5 of IEC 60079-14:2013. It was 
not our intent to add wiring and cabling system requirements to Sec.  
111.105-3. The requirements for wiring and cable systems in hazardous 
locations are in Sec.  111.105-17.
    One commenter noted that both Clauses 8 and 9 of IEC 61892-7 
reference IEC 60079-14, Electrical installations design, selection, and 
erection, and suggested that we should incorporate IEC 60079-14 by 
reference. We disagree with the suggestion. Since we incorporated by 
reference IEC 61892-7:2007 in 46 CFR subchapter J, the standard has 
evolved and been updated twice. In 2014, the IEC 61892-7 requirements 
for installations in hazardous area were rewritten based on the 
requirements of IEC 60079-14:2013. In the latest edition, 2019, IEC 
61892-7 was completely rewritten and references are, to the extent 
possible, made to IEC 60079-14:2013 and to other relevant standards. At 
this time our intent is to only apply IEC 60092-14:2013 as it is 
referenced in Clause 8 of IEC 618792-7:2019. We describe Clause 8 in 
the previous paragraph. Despite the commenter mentioning Clause 9 of 
IEC 61892-7:2019, we did not propose to incorporate it in the NPRM. We 
already address the cable and wiring requirements using standards we 
deem sufficient in Sec.  111.105-17. It is commonplace for standards to 
reference other standards, but incorporating every standard simply 
because it is cross-referenced would cause us to incorporate more 
standards than are reasonably necessary to convey the relevant 
requirements. A broader incorporation by reference of IEC 61892-7:2019 
would require additional regulatory analysis and an additional 
opportunity for the public to review and comment.
Sec.  111.105-28 Internal Combustion Engines
    A commenter said that Sec.  111.105-28 states ``Internal combustion 
engines installed in Class I Divisions 1 and 2 (Zones 1 and 2),'' but 
there is no direct equivalency between Class I Division 1 and Zone 1 as 
Class I Division 1 covers equipment in Zone 0 as well. The commenter 
suggested that references to Class I Divisions (1 and 2) and Zones be 
removed from the section. We disagree with this suggestion. Currently, 
Sec.  111.108-1(b) allows U.S. Mobile Offshore Drilling Units (MODUs), 
floating OCS facilities, and vessels other than Offshore Supply Vessels 
(OSVs) regulated under 46 CFR subchapter L and U.S. tank vessels that 
carry flammable and combustible cargoes, to comply with ASTM F2876 per 
Sec.  111.108-3(g). Our purpose in changing Sec.  111.105 is to improve 
the consistency of the regulations related to hazardous areas in 
Sec. Sec.  111.105, 111.106, and 111.108. It does not change the 
requirements. Although we agree with the commenter's assertion that 
Class I Division I may also cover equipment in IEC Zone 0, internal 
combustion engine installations are generally prohibited for use in 
shipboard IEC Zone 0 areas.
    A commenter noted that engines may be certified by the manufacturer 
to ASTM F2876 and its maximum surface temperature requirements. The 
commenter also noted that ASTM F2876 does not address different testing 
requirements from Zone 1 and Zone 2 applications. The primary purpose 
of ASTM F2876 is determining the maximum operating temperature of the 
engine, in order to ascertain the suitability of the engine 
installation in hazardous areas associated with the autoignition 
temperature of various flammable cargoes. An independent laboratory 
must certify all electrical equipment associated with the engine 
installation. Although ASTM F2876 contains other requirements in 
addition to temperature measurement, the references to EN 1834-1 within 
ASTM F2876 are recommendations only.
Sec.  111.105-50 Alternative Standard to the Classification of 
Hazardous Locations Requirements of This Subchapter
    A commenter noted we proposed in the NPRM to incorporate IEC 60092-
502 without also incorporating the Coast Guard's interpretations and 
additional requirements, issued in April 2009, which we maintain on the 
Coast Guard's website for the ACP.\4\ The commenter did not offer an 
opinion or recommendation on this proposal, but asked us to clarify if 
these requirements in the IEC 60092-502 Supplement would be obsolete 
when we incorporate IEC 60092-502:1999. The intent of these 
interpretations and supplemental requirements was for vessels in the 
ACP to achieve equivalency with the regulations in 46 CFR. The Coast 
Guard has determined that IEC 60092-502, even without these 
interpretations and supplemental requirements, is a satisfactory 
alternative method for the classification of hazardous locations. When 
using IEC 60092-502 to classify hazardous locations, vessels no longer 
need to comply with our IEC 60092-502 Supplement issued in April 2009.
---------------------------------------------------------------------------

    \4\ See U.S. Coast Guard Interpretation: IEC 60092-502:1999 
Supplement at https://www.dco.uscg.mil/Portals/9/DCO%20Documents/5p/5ps/Alternate%20Compliance%20Program/iec60092-502sup.pdf.
---------------------------------------------------------------------------

    A commenter said that our proposed incorporation by reference of 
IEC 60092-502:1999 as an alternative method for classification of 
hazardous location, while also referencing Sec. Sec.  32.60-20(c) and 
38.20-10, resulted in conflicting ventilation requirements. We agree 
that they can be conflicting. Unfortunately, existing U.S. and 
international requirements for cargo pump room ventilation are 
different. Sections 32.60-20(c) and 38.20-10 both require an air change 
every 3 minutes (20 air changes per hour) while Clause 8.1.3 of IEC 
60092-502:1999 requires an air change every 2 minutes (30 air changes 
per hour). We intend for IEC 60092-502:1999 to be an alternative to 
existing regulations. At this time we are not changing 46 CFR 
subchapter D, including Sec. Sec.  32.60-20(c) and 38.20-10,

[[Page 16319]]

nor modifying IEC 60092-502. System designers choosing to use IEC 
60092-502:1999 for classification of hazardous locations must follow 
the standard. However, we are revising Sec.  111.105-50(c) from what 
was proposed in the NPRM to clearly state when 30 air changes per hour 
are required. Specifically, if IEC 60092-502:1999 is used, cargo 
handling rooms and other spaces where hazardous location classification 
is dependent upon ventilation must have mechanical ventilation capable 
of at least 30 air changes per hour, based upon the gross volume of the 
space.

Subpart 112.05--General

Sec.  112.05-5 Emergency Power Source
    Section 112.05-5(a) requires that an emergency power source have 
the capacity to simultaneously supply all loads connected to it. To 
further clarify this, in the NPRM we suggested adding the phrase ``at a 
unity (1.0) service factor.'' This simply means the emergency power 
source must be sufficiently sized to operate all loads at their full 
rated capacity.
    A commenter requested we modify the required capacity of the 
emergency power source with a phrase such as ``with due regard being 
paid to such services as may have to be operated simultaneously.'' They 
stated that their proposed change would allow use of emergency 
generators that are more closely sized to the loads that would be 
needed in an emergency. We disagree with the commenter's proposed 
change. It would change the intent of the existing regulation by 
allowing more discretion and ambiguity than a specific load capacity 
measurement. In the interest of providing a clear discernable standard 
that we considered safe, we will proceed with requiring the unity 1.0 
service factor as proposed in the NPRM.
    In table 1 to Sec.  112.05-5 footnote 2, we are replacing the 
reference to Sec.  111.93 with a reference to Sec.  58.25-65 because we 
moved the requirements in Sec.  111.93 to Sec.  58.25-65 in a previous 
rulemaking (60 FR 24776, May 10, 1995). Although we did not include 
this amendment in the NPRM, this is a conforming edit that will not 
have an impact on the existing emergency power requirements.
Sec.  112.05-7 Use of Emergency Generator in Port
    A commenter noted that existing Coast Guard policy regarding in 
port use of the emergency generator requires that a qualitative failure 
analysis (QFA), design verification test procedure (DVTP), and a 
periodic safety test procedure (PSTP) be submitted for review, but the 
proposed Sec.  112.05-7 did not have this requirement. This is correct. 
The requirements for these documents are contained in 46 CFR subchapter 
F Subpart 61.40. Based on this subpart, an emergency generator intended 
to meet Sec.  112.05-7 for use in port would be required to submit a 
QFA, DVTP, and PSTP for review. We do not see the need to duplicate 
this requirement in Sec.  112.05-7.
    A commenter said we could require more comprehensive alarms in 
Sec.  112.05-7(c) and requested that, at a minimum, we consider 
clarifying the alarms and shutdowns required versus the shutdowns 
allowed or disallowed. We understand the commenter's intent and request 
for more specific information, but this regulation provides the 
baseline requirements. We do not agree with revising the regulation to 
require additional alarm regulations at this time because we have 
determined that the baseline alarm requirements are still adequate.
    A commenter noted that the proposed regulations regarding in-port 
use of the emergency generator at Sec.  112.05-7(c) require the vessel 
be equipped with displays and alarms in the centralized control station 
and alarm monitoring at the engineers' quarters. The commenter pointed 
out that not all ships have a centralized control station or alarm 
summary panels in the crew's quarters. These regulations set the 
baseline requirements for in-port use of the emergency generator. If a 
system designer cannot meet the requirements due to unique ship 
characteristics, the designer may propose equivalent arrangements to 
the MSC in accordance with Sec.  110.20-1. Our intent for these alarm 
location regulations is to require alarms both where the emergency 
generator is normally controlled and where crew would normally be 
located in port.
    Additionally, two commenters noted that the NPRM did not discuss 
arrangements for feedback to power the vessel's main switchboard for 
habitability services and any special load analysis considerations or 
interlocks requirements for paralleling with main generators. Following 
our review, we find that there is not a need to include provisions on 
these points because the existing Sec.  112.05-3(c) and the new Sec.  
112.05-7(g) both address use of the emergency generator to feedback to 
non-emergency loads and require either disconnection or automatic load 
shedding of these loads before the emergency generator is overloaded.
    Another commenter was concerned that Sec.  112.05-7(e) appeared to 
be describing requirements for breaker coordination to main services 
while using the emergency generator in port. This is true, and this 
coordination is not a new requirement. Subpart 111.51 requires 
coordinated protection and selective operation of overcurrent 
protective devices for all potential plant configurations, including 
this situation. Section 112.05-7(e) clarifies that in port use of the 
emergency generator is one of the configurations requiring coordination 
of overcurrent devices in accordance with Sec.  111.51-5(a). Per the 
requirements of this rule, the power supply circuits for the use of an 
emergency generator in port must be arranged and protected to ensure 
that any electrical fault (except for the emergency generator and the 
emergency switchboard) will not affect the operation of the main and 
emergency services. The commenter was concerned this requirement could 
be interpreted to require full breaker coordination, which they believe 
is not feasible on many vessels with large distribution breakers from 
the main switchboard not designed to coordinate with a small power 
source such as the in-port generator. The commenter requested we remove 
references to protecting the main power system while using emergency 
generator in port from these regulations, noting that the intent of the 
rule is to ensure the availability of the emergency power system if it 
is being used as the power source while in-port. We understand the 
commenter's concerns, but, as explained in Section V.E, this provision 
has been accepted by IMO since 2005 and is similarly addressed in 
classification society rules. It is true that many of the provisions in 
this section are aimed at ensuring the availability of the emergency 
generator in port, but it is also important that the power circuits for 
the main distribution system are appropriately protected when powered 
by the emergency generator. We recognize that full coordination may not 
always be possible because of the large variation in short currents due 
to different operational conditions, but the coordination study must 
demonstrate main power system circuits connected to the emergency 
generator in port are adequately protected against short circuit. For 
these reasons we did not make any changes to the regulatory text 
originally proposed for Sec.  112.05-7.

Subpart 112.15--Emergency Loads

Sec.  112.15-1 Temporary Emergency Loads
    As provided in the NPRM, in Sec.  112.15-1 we will now require an 
engineer's assistance-needed alarm as a

[[Page 16320]]

required temporary emergency load. A commenter correctly noted that 
adding the alarm as a temporary emergency load meant that it would also 
be a final emergency load. This is correct. In accordance with Sec.  
112.15-5(a), temporary emergency loads are also final emergency loads.

Regulatory Analysis Comments

    A commenter asserted that table 3, ``Affected U.S.-Flagged Vessel 
Population That Complies with 46 CFR Subchapter J,'' on page 21462 of 
the NPRM, does not provide enough clarity to determine whether floating 
OCS facilities are excluded or included under the vessel count for 
``Cargo and Miscellaneous Vessels.'' The commenter also encouraged the 
Coast Guard to make changes to the Marine Information for Safety and 
Law Enforcement (MISLE) database and Coast Guard documentation to 
ensure this and future rulemakings clarify whether floating OCS 
facilities are included or excluded.
    Another commenter expressed a concern regarding table 3, suggesting 
that, despite what may be currently listed in MISLE, the latest tally 
of U.S.-flagged MODUs is less than 5, and likely comprises only the 
Helix Q4000 and Enterprise Offshore Drilling's EOD 201, and possibly 
the Spartan Rigs 202 and 303. The commenter suggested we revise table 3 
of the proposed rule to read ``<5'' to more accurately reflect the 
scope of subchapter J's application to U.S.-flagged MODUs.
    We agree with these commenters' assertions that we incorrectly 
counted the number of Cargo and Miscellaneous Vessels. Our MISLE 
database listed floating production systems as being inspected under 
Title 46 of the CFR, subchapter I-A. This is incorrect. As a result, we 
overstated the number of MODUs in the regulatory analysis (RA) for the 
proposed rule, which lowered the population of vessels in the ``Cargo 
and Miscellaneous Vessels'' category for the final rule. After further 
analysis, we revised the population of MODUs to one: the Helix Q4000. 
This is the only MODU in our MISLE database. Therefore, the number of 
MODUs for the final rule is one because we incorrectly classified the 
rest based on the subchapter inspection field in MISLE. We added the 
population of 41 floating production systems in our MISLE database to 
the final rule RA's category of ``Cargo and Miscellaneous Vessels'' 
inspected under subchapter I, which we present in table 4 of the RA. 
The number of vessels in this category increased from 576 in the 
proposed rule to 617 in the final rule. Because we updated the entire 
vessel population for this final rule, the total number of vessels 
increased from 5,570 in the proposed rule to 5,602 (see table 4).

V. Discussion of the Rule

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

    The standards that are incorporated by reference in subchapter J 
are listed in Sec.  110.10-1. With this rule, the Coast Guard updates 
the technical standards to reflect 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.
    We incorporate by reference the class rules of ABS, in particular, 
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.\5\ The Coast Guard 
authorized the listed classification societies to perform certain 
functions and certifications using their respective class rules on 
vessels enrolled in the ACP. Vessels not enrolled in the ACP 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.

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

    Throughout Sec.  110.10-1, we also add additional standards to 
provide alternative compliance options, remove outdated standards, and 
clarify existing requirements. Where applicable, we 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 are updating, 
adding, or deleting in Sec.  110.10-1. Within each standard listed, we 
describe the topics covered by the standard, the 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 rule does not make any changes to a standard that is currently 
incorporated by reference, the standard will not be discussed in the 
revisions to Sec.  110.10-1. However, it will be included, without 
change, in the regulatory text of Sec.  110.10-1 that appears at the 
end of this document.
     ABS Rules for Building and Classing Marine Vessels (ABS 
Marine Vessel Rules), 2020. The rules contain a comprehensive set of 
construction and maintenance requirements for ships and offshore 
facilities. The rules are, in general, developed by the International 
Association of Classification Societies (IACS) and by ABS staff, and 
reviewed and approved by committees made up of naval architects, marine 
engineers, shipbuilders, engine builders, steel makers and by other 
technical, operating, and scientific personnel associated with the 
worldwide maritime industry. Because of classification society rules' 
comprehensive nature and ABS's long history of ensuring vessel safety 
and seaworthiness, they are a valuable supplement to the numerous 
voluntary consensus standards incorporated by reference. In subchapter 
J the rules provide an option for the design of engineering systems and 
components 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(a) and (b), 111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n), 
111.105-39 introductory text and (a), 111.105-40(a) and (c), 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 incorporate by reference the 2020 
ABS Marine Vessel Rules in the aforementioned sections and additionally 
in the new 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. We are incorporating by reference the following 
parts of the ABS Marine Vessel Rules: Parts 1, 2, 3, 4, 5A, 5B, 5C, 5D, 
6, and 7. Several of the sections of the ABS Marine Vessel Rules that 
we incorporate

[[Page 16321]]

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 the 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. The rules contain 
a comprehensive set of construction and maintenance requirements for 
mobile offshore drilling units. In subchapter J the rules provide an 
option for the design of engineering systems and components 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. By means of this 
rule, we 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.
     ANSI/IEEE C37.12[dash]1991--American National Standard for 
Alternating Current (AC) High-Voltage Circuit Breakers Rated on a 
Symmetrical Current Basis-Specifications Guide. We 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 1000 V), 2008. This represented 
a complete technical revision of the standard. IEEE subsequently 
revised it again in 2018. We 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 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/ISA-RP12.06.01-2003--Recommended Practice for Wiring 
Methods for Hazardous (Classified) Locations Instrumentation Part 1: 
Intrinsic Safety. This recommended practice provides guidance on 
installation of intrinsically safe systems for use in hazardous 
(classified) locations. It clarifies and explains the requirements of 
Articles 504 and 505 of NFPA 70 (National Electrical Code). This 
recommended practice supersedes ISA RP 12.6-1995. By means of this 
rule, we delete ISA RP 12.6 from reference in Sec.  111.105-11 and 
replace it with ANSI/ISA-RP12.06.01-2003.
     ANSI/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 replaces 
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 include ANSI/ISA 12.12.01-2015 in Sec. Sec.  111.105-
3(b) and 111.106-3(b) as another certification option for electrical 
equipment in hazardous location. The 2015 edition contains 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 rule removes the 
ANSI/ISA-60079-18 references in Sec. Sec.  111.106-3(d) and 111.108-
3(e) because the standard has been withdrawn and replaced by UL 60079-
18, a substantively similar standard. We replace the ANSI/ISA standard 
with UL 60079-18 in Sec.  111.106-3(d) and 111.108-3(e).

     ASME A17.1-2016/CSA B44-16--Safety Code for Elevators and 
Escalators: Includes Requirements for Elevators, Escalators, 
Dumbwaiters, Moving Walks, Material Lifts, and Dumbwaiters with 
Automatic Transfer Devices, reissued January 16, 2017 with errata. 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. By means of this rule, 
we reference instead 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 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). By means of this rule, we reference instead the 2019 
edition. The 1997 edition has been superseded by several subsequent 
editions. ASTM made the following changes over the recent editions of 
this standard that are ultimately incorporated into the 2019 version we 
adopt in this rulemaking. 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.

short-circuit currents in three-phase a.c., first edition, 1998-02. 
This standard outlines procedures for calculating short-circuit 
currents that may occur on a marine or offshore a.c. electrical 
installation. By means of this rule, we will make formatting changes to 
the standard's title for consistency with the titles of all other 
referenced IEC standards, but this rule does not alter the edition 
currently incorporated by reference. We currently reference this 1998 
edition in Sec.  111.52-5. This rule will move the standard to the new 
Sec.  111.51-4(b) because we are 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. By means of this rule, we add 
it to the revised Sec.  111.59-1 concerning general requirements for

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). By means of this 
rule, we update

[[Page 16331]]

the reference in Sec.  111.108-3(b) to the more recent edition 4.0 
(2019) and insert new references to this standard in Sec. Sec.  
111.105-1, 111.105-3(b), 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 provides an 
alternate standard for classifications for hazardous locations.
     IEC 62271-100:2017 (Consolidated Version)--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). By means of this rule, we 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 incorporate 
the more recent edition of this standard.

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). By means of this rule, we reference this new standard in Sec.  
111.60-1. This aligns 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. Some ships may 
voluntarily connect to an HVSC. In Sec.  111.83-7, we provide this 
standard as a recommended compliance standard for all applicable 
vessels that connect to an HVSC.
     SOLAS Consolidated Edition 2014, 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), Sixth edition, 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, by 
means of this rule, incorporate instead the 2014 edition of SOLAS. 
While the applicable sections of SOLAS referenced in these requirements 
were not changed in the 2014 edition, we are incorporating these SOLAS 
amendments for completeness because industry is likely to use the more 
recent edition.
     IMO Resolution A.1023(26)--Code for the Construction and 
Equipment of Mobile Offshore Drilling Units, 2009. We make a non-
substantive formatting change to the listing of this resolution in

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). By means of this rule, we replace these references 
with a reference to the more recent 2017 edition in all the 
aforementioned sections where the NFPA 70 code is referenced except for 
Sec.  111.105-7, which we are merging into Sec.  111.105-3. We also 
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 from 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 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--The applicability of this article on switches 
has been raised from 600 V systems to 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 have 
been adopted, including adding references to 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 will 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). By means of this rule, 
we reference instead the more recent 2019 edition, which has been 
completely reorganized with only minor changes to the technical 
content. However, the 2019 edition contains changes regarding the 
characterization of low, medium, and high resistivity powders to 
reflect generally accepted international standards.
     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. By means of this rule, we instead 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

[[Page 16333]]

in hazardous locations. NFPA 496 has been an industry standard for 
purged and pressurized enclosures since 1971. 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). By means of this rule, we 
update the references to the more recent 2017 edition in Sec. Sec.  
111.105-3 (formerly Sec.  111.105-7), 111.106-3(c), and 111.108-3(d). 
This more recent edition of NFPA 496 was revised to ensure correlation 
with NFPA 70. The definitions of ``energized'' and ``identified'' are 
extracted from NFPA 70, clarify the requirements for equipment in 
hazardous areas, clarify the definitions of Type X, Type Y, and Type Z 
pressurization, and remove 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. By means of this rule, we will 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 reorganize the requirements for short-circuit calculations 
for systems 1500 kW or above in Sec.  111.52-5 into new Sec.  111.51-4. 
The other three options that are currently in Sec.  111.51-4 are still 
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. By means of this rule, we 
delete this standard because we are also rescinding Sec.  111.60-3, 
which we discuss in section VI.C of this preamble, because we have 
found that it is 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). By 
means of this rule, we 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. Previously this standard 
did not cover wires or cables above 2000V. Additionally, the nineteenth 
edition (2018) addresses new wire types and maximum voltage ratings 
that were not included in the fifteenth edition (1999).
     UL 50--Standard for Safety Enclosures for Electrical 
Equipment, Non-Environmental Considerations, 2015. This standard covers 
the non-environmental construction and performance requirements for

and non-shielded medium-voltage power cables. We currently reference 
the third edition (2001) of this standard in Sec.  111.60-1(a). By 
means of this rule, we reference the more recent fourth edition (2013). 
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 Safety 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(d). By means of this rule, we will align the naming 
convention in the regulatory text with that of other UL standards and 
specifically cite paragraph (d) in Sec.  110-10-1(q).
     UL 1203--Standard for Safety: Explosion-Proof and Dust-
Ignition-Proof Electrical Equipment for Use in Hazardous (Classified) 
Locations, revised April 24, 2015. This standard covers explosion-proof

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). By means of this rule, we 
reference the more recent fifth edition (2015) in Sec.  111.105-3(b) 
instead of Sec.  111.105-9 due to editorial reformatting of subpart 
111.105, as well as Sec. Sec.  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), 
control, and signal cables for installation aboard marine vessels, 
fixed and floating offshore petroleum facilities, and 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). By means of this rule, 
we reference the more recent third edition (2017) only in Sec. Sec.  
111.60-1 and 111.106-5(a) because we 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. By means of this 
rule, we 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,

[[Page 16335]]

has been moved to UL 2556, which is added to these sections as 
discussed below.
     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. By means of this rule, we 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 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. UL 1598, the First 
Edition, December 4, 2000, is currently incorporated by reference in 
Sec.  111.75-20. By means of this rule, we incorporate UL 1598A, the 
First Edition with revisions through April 17, 2015 in that 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 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. This 
was one of many options in Sec.  111.108-3(b) for standards on 
electrical equipment in hazardous locations. By means of this rule, we 
delete this standard from Sec.  111.108-3(b) because UL withdrew this 
standard and it is no longer active.
     UL 2021--Standard for Safety Fixed and Location-Dedicated 
Electric Room Heaters, 2015. By means of this rule, we reference this 
standard in Sec.  111.87-3(a) for the first time. This standard 
provides requirements for electric air heaters. It will be an 
additional standard regulated entities may choose for electric air 
heaters. The Coast Guard has 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. This standard 
contains construction and testing requirements for cables and cable-
fittings for use in hazardous locations. 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). By means 
of this rule, we reference the more recent fourth edition (2013) in 
Sec. Sec.  111.105-3(b), 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. 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. By means of this 
rule, we will replace UL 1581 with UL 2556 in Sec. Sec.  111.30-19(b), 
111.60-2, and 111.60-6.
     UL 60079-18--Standard for Safety Explosive Atmospheres--
Part 18: Equipment Protection by Encapsulation ``m'', Fourth Edition, 
revised February 20, 2017. By means of this rule, we adopt this 
standard as a replacement for ANSI/ISA 60079-18, which was withdrawn by 
ISA. 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 reference this standard in Sec. Sec.  111.105(e), 
111.106-3(d), and 111.108-3(e).

B. Generator Prime Movers

    By means of this rule, we will delete the requirements in 
Sec. Sec.  111.12-1(b) and (c) for each generator prime mover to have 
an independent overspeed device and to automatically shut down upon a 
loss of lubricating oil pressure to the generator bearing. The Coast 
Guard has required generator prime movers to meet ABS rules since 1965. 
We incorporate the ABS Steel Vessel Rules for generator 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. The ABS Steel Vessel Rules, which are already 
incorporated by reference in Sec.  58.01-5,\6\ 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 horsepower (hp)) and above, while the oil pressure shutdown is 
required for generators of 100 kW (135 hp) and above. Because vessels 
will have to comply with the ABS Steel Vessel Rules, there is no need 
to duplicate these requirements in Sec.  111.12-1, and we find that the 
requirements in the incorporation by reference sufficiently address the 
concerns that Sec.  111.12-1(b) and (c) were intended to address.
---------------------------------------------------------------------------

    \6\ We note that Sec.  58.01 currently incorporates by reference 
the 2003 edition of the ABS Steel Vessel Rules. On October 18, 2021 
we proposed in Updates to Marine Engineering Standards, 86 FR 57896 
(Oct. 19, 2021) (proposed rule) to update the reference in Sec.  
58.01 to the 2020 edition of the ABS Marine Vessel Rules.. This is 
the same edition incorporated by reference in Sec.  110.10-1(a). If 
we amend Sec.  58.01 through a final rule on this same topic, any 
changes made would not conflict with the intent of Sec.  111.12-1. 
Generator prime movers will have to meet the ABS Marine Vessel Rules 
incorporated by reference in Sec.  58.01.
---------------------------------------------------------------------------

C. Electrical Cable

    This rule updates and amends subpart 111.60 (Wiring Materials and 
Methods) to align it more closely with the standards accepted 
internationally by vessel classification societies and foreign 
administrations.
    This rule adds additional acceptable cable construction standards 
to Sec.  111.60-1. In addition, due to the availability of widely 
accepted additional standards, this rule removes many of the more 
prescriptive cable requirements in Sec. Sec.  111.60-3 and 111.60-4.
    We also are rescinding Sec.  111.60-3, which sets out the cable 
application regulations, because we find that those regulations are 
unnecessarily prescriptive. Instead, entities will consult the cable 
construction standards in Sec.  111.60-1, as revised by this rule, for 
the application of specific types of cable.
    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 will 
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. Both the existing and revised regulations 
regarding cable splices in Sec.  111.60-19 refer to IEEE 45's 
recommendations for cable splices.

[[Page 16336]]

    Additionally, in Table 111.60-7--Demand Loads, we make minor edits 
so that ``bus-tie'' and ``feeder'' are plural where they appear in the 
table. As previously mentioned in the IBR updates to Sec.  110.10-1, we 
will also update the NFPA NEC 2002 standard to its newer edition, NFPA 
70, where it appears in the table.
    In the NPRM, we proposed to update the existing IEEE 45 reference 
in Sec.  111.60-11(c) to section 5.7 of the 2016 version. A commenter 
correctly noted this section does not address wire, so we removed 
section 5.7 of IEEE 45.8 from the list of standards. The final rule 
leaves the following updated standards to choose from: NPFC MIL-W-76D, 
ANSI/UL 44, ANSI/UL 83, or an equivalent standard.

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

    This rule amends our regulations for hazardous locations contained 
in Subpart 111.105 to allow the Coast Guard to accept IEC 60092-
502:1999 as an option for classification of hazardous locations (areas) 
in the new Sec.  111.105-50. New section 111.105-50(a) contains an 
alternative standard 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 section provides instructions 
for how to use the IEC 60092-502:1999 option for the classification of 
hazardous locations as well as specific requirements for ventilation 
systems if system designers use IEC 60092-502:1999. 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 ACP 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.'' \7\ The Coast Guard 
developed these supplemental requirements to ensure an equivalent level 
of safety as the requirements of subpart 111.105. Through this rule, 
the Coast Guard will 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 will accept it as an option for U.S. vessels.
---------------------------------------------------------------------------

    \7\ 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 specify 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 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. As noted in 
the discussion of the comment section, this final rule also clarifies 
that the mechanical ventilation must be capable of at least 30 air 
changes per hour, based upon the gross volume of the space, for cargo 
handling or pump rooms and other spaces where hazardous location 
classification is dependent upon ventilation.
    In the final rule, we also break down paragraph (c) into multiple 
subparagraphs to help with readability. This change is an editorial 
amendment that does not result in any substantive changes from what we 
proposed in the NPRM.

E. Emergency Generator in Port

    This rule amends our regulations for a vessel's emergency power 
sources contained in subpart 112.05 to allow the emergency generator to 
be used in port in the new Sec.  112.05-7. The current regulations in 
Sec.  112.05-1 require 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, IACS 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. The IMO subsequently adopted this proposal in 2005, promulgated 
it in IMO circular MSC/Circ.1176 (dated May 25, 2005), and updated it 
in IMO circular MSC.1/Circ. 1464/Rev.1 (dated October 24, 2013). Since 
then, most classification societies and flag states have harmonized 
their rules to align with this interpretation.
    Similar to the IMO, by means of this rule we will 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, 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 arrangements will result in improved performance, better 
fuel economy, lower emissions, and higher reliability than less 
integrated systems.
    For these reasons, this rule will allow the emergency generator to 
be used in port provided that supplemental safety standards are in 
place. The supplemental safety standards incorporated 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.

[[Page 16337]]

F. Description of Additional Changes Within Subchapter J \8\
---------------------------------------------------------------------------

    \8\ In addition to the changes specifically discussed in this 
preamble, we note that we have made additional non-substantive edits 
for clarity following the NPRM. For example, we removed the word 
``both'' in Sec.  111.87-3 because, following the addition of a new 
standard as discussed elsewhere in this rule, ``both'' was no longer 
an accurate description.
---------------------------------------------------------------------------

Sec.  110.15-1 Definitions
    This rule adopts 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 are 
moved from Sec.  111.10-1(a) to Sec.  110.15-1 so that all definitions 
for subpart J are in one location.
Sec.  110.25-1 Plans and Information Required for New Construction
    We have consolidated the hazardous locations plan submittal 
requirements of the existing Sec.  110.25-1(i), (p), and (q) into a 
single section, Sec.  110.25-1(i). 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 will 
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.
    This rule makes one addition to the list of required items to be on 
the plan submission under existing Sec.  110.25-1(i). The plan must 
clearly indicate the method of classification, Division or Zone, of the 
hazardous location. This information is important to ensure appropriate 
selection of equipment for the hazardous location.
Sec.  111.05-3 Design, Construction, and Installation; General
    In Sec.  111.05-3(c), we clarify the grounding requirements for 
appliances and tools so that the requirements are consistent with 
current industry practice.
Sec.  111.10-9 Ship's Service Supply Transformers; Two Required
    This rule revises the note to Sec.  111.10-9 to clarify that 
transformers located downstream of the ship's service switchboard are 
not required to be provided in duplicate. This item is regularly 
misunderstood. This revision is consistent with the explanation on page 
16 of NVIC 2-89, ``Guide for Electrical Installations on Merchant 
Vessels and Mobile Offshore Drilling Units,'' dated August 14, 1989.\9\
---------------------------------------------------------------------------

    \9\ 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.
---------------------------------------------------------------------------

Sec.  111.12-11 Generator Protection
    In this section and many other sections, we replace the term 
``semiconductor rectifier (SCR)'' with ``semiconductor converter,'' 
which is a term now more commonly used in industry.
Sec.  111.12-13 Propulsion Generator Protection
    We are deleting this section on propulsion generator protection 
because it is simply a reference to Sec.  111.35-1. This cross-
reference is not necessary.
Sec.  111.15-10 Ventilation
    In Sec.  111.15-10(b)(2)(i), we add the IEC equivalent 
classification of Class I, Division 1, Group B as an alternate 
standard.
Sec.  111.25-5 Marking
    Under Sec.  111.25-1, motors are required to meet the requirements 
for generators in Sec.  111.12-5. That section in turn incorporates by 
reference section 4-8-3 of the ABS Marine Vessel Rules, which means 
that motors must meet that standard. Because the ABS Marine Vessel 
Rules sufficiently address requirements for motor marking, we are 
deleting this section on motor markings as unnecessary.
Sec.  111.30 Switchboards
    The requirements for switchboards contained in IEEE 45 2002 are 
replaced with requirements from the recently published IEEE 45.7 
(2012), excluding section 6.3.3 related to steering gear circuit 
overcurrent protection. We did not intend the NPRM to propose a change 
the existing requirements for steering gear circuit overcurrent 
protection. For this reason, in Sec.  111.30-5(a)(1) of this final 
rule, we are incorporating section 6 of IEEE 45.7-2012, excluding 
section 6.3.3 as discussed above in response to comments received on 
the NPRM.
    In the NPRM, we had proposed a new paragraph (c) that warned 
readers that the interchangeability and compatibility of components 
complying with both IEEE and IEC cannot be assumed. That effort was to 
address the growing use of components meeting IEC standards on U.S. 
vessels. As noted in the discussion of the comments related to Sec.  
111.30-5, we have opted to remove paragraph (c) from the final rule 
because complying with and enforcing this relatively vague requirement 
would be difficult. Switchboards should be constructed in accordance 
with the standards incorporated by reference in subpart 111.30.
    The flame retardant test standard IEC 332-1 has been superseded by 
IEC 60332-1-1:2015 and IEC 60332-1-2:2015. We are updating the 
standards for the flame retardant test in Sec.  111.30-19(b)(4) 
regarding buses and wiring accordingly.
    This rule replaces the term ``pilot light'' with the more commonly 
used term ``indicator light.''
Subpart 111.33 Power Semiconductor Rectifier Systems
    We are replacing the requirements for semiconductor converters 
contained in IEEE 45 2002 with requirements from the recently published 
IEEE 45.2 (2012).
Sec.  111.50-3 Protection of Conductors
    In Sec.  111.50-3(b)(2), we revise the requirement for steering 
gear circuits from subchapter F to a more specific cite of Sec.  58.25. 
We also remove the reference to IEC 92-202 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
    This rule combines 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 new Sec.  111.51-
2(a) are from the existing Sec.  111.52-1. The new Sec.  111.51-2(b) 
clarifies that the calculations must be performed to select suitably 
rated equipment and protective devices. The short-circuit calculations 
requirements of the new Sec. Sec.  111.51-3 and 111.51-5 are from the 
existing Sec. Sec.  111.52-3 and 111.52-5, respectively.
    We are deleting NAVSEA DDS 300-2 from the existing Sec.  111.52-
5(b) because it is no longer available. Instead, we add IEC 61660-
1:1997 as a standard for DC systems.
    The requirements for the protection of vital equipment, Sec.  
111.51-6, are from the existing Sec.  111.51-3.

[[Page 16338]]

Sec.  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 will be identified as 1500 V. 
This is in accordance with that standard.
Sec.  111.75-17 Navigation Lights
    In Sec.  111.75-17(a), this rule removes the requirement that a 
feeder directly from the emergency switchboard supply the navigation 
light indicator panel. The emergency switchboard must still supply the 
panel, but this change allows for the common practice of supplying 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 also delete Sec.  112.43-13, which provided details on the 
navigation light panel feeder.
    In Sec.  111.75-17(d)(2), we will offer EN 14744 as an alternative 
for certification of navigation lights. UL 1104, which is currently the 
only certification specifically referenced in Sec.  111.75-17(d)(2), is 
the other acceptable standard, but it has not been updated in over 20 
years and addresses neither LED light sources nor EMC testing. EN 14744 
addresses LED lights and EMC testing and has been published for 15 
years. The other construction and testing requirements of EN 14744 are 
not identical to UL 1104, but it is accepted worldwide. 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. The Coast 
Guard currently accepts navigation lights constructed and tested to the 
requirements of EN 14744 on a case-by-case basis subject to the 
additional requirements of the MSC`s Marine Technical Note 01-18, 
Guidance for Establishing Equivalency to UL 1104 Navigation Lights.\10\ 
Following the publication of this final rule, we will accept EN 14744 
without these additional requirements.
---------------------------------------------------------------------------

    \10\ 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), this rule clarifies the 
requirements for battery powered navigation lights. The existing text 
has been misinterpreted on occasion. Like all navigation lights, these 
lights must be certified by an independent laboratory to the applicable 
requirements of UL 1104, EN 14744, or an equivalent standard. This 
ensures they meet the applicable requirements of the 1972 COLREGS and 
the Inland Navigation Rules (33 CFR 83).
    This rule deletes the requirement for a flashing light in the 
existing Sec.  111.75-17(d)(4) because this requirement is contained in 
section 22.11 of UL 1104 and section 4.4 of EN 14744.
Sec.  111.75-18 Signaling Lights
    This rule deletes the outdated, prescriptive requirements on 
signaling lights in this section that were based on the applicable 
international requirements in 1996 and incorporates 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.
Sec.  111.75-20 Luminaires (Lighting Fixtures)
    Throughout this section, we replace the term ``lighting fixture'' 
with the internationally used term ``luminaire,'' and we remove the 
prescriptive requirements contained in this section. Lighting fixtures 
meeting the standards incorporated by reference in this section, ANSI/
UL 1598A or IEC 60092-306:2009, are suitable for use on vessels. 
Further, this rule specifies the clauses of ANSI/UL 1598A applicable to 
nonemergency and inside-type decorative luminaires.
Sec.  111.83-7 High Voltage Shore Connection
    This section contains a standard for HVSCs, IEC/IEEE 80005-1:2019, 
applicable to ships that 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 HVSCs. This standard is offered as an 
option for compliance with state or local law, or when a vessel 
voluntarily connects to an HVSC.
Sec.  111.99-3 Definitions
    We remove this section of definitions because the definitions are 
no longer necessary. Fire door holding and release systems are 
discussed in greater detail in SOLAS II-2/9. Many years ago there were 
detailed fire door system requirements in Sec.  111.99. Now Sec.  
111.99-5 requires fire door holding and release systems, if fitted, to 
meet SOLAS II-2/9.4.1.1.5.3. Previously, Sec.  111.99-5 required these 
systems to meet SOLAS II-2/30.4.3, but we have updated this reference 
to SOLAS II-2/9.4.1.1.5.3 based on the reorganization of SOLAS Chapter 
II-2.
Subpart 111.103 Remote Stopping Systems
    The order of the subsections in 46 CFR subpart 111.103 has caused 
confusion and led readers to incorrectly infer that machinery space 
ventilation is a separate category from the ventilation referred to by 
46 CFR 111.103-7. We are making editorial changes to this section to 
clarify its intent.
Subpart 111.105 Hazardous Locations
    The Coast Guard 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 are revising subpart 111.105 (Hazardous Locations) to be 
consistent with existing regulations. This final rule expands the list 
of acceptable national and international explosion protection 
standards, providing more options for operators. Additionally, in this 
final rule, we combine important provisions from Sec. Sec.  111.105-3, 
111.105-5, and 111.105-7 into one revised section, Sec.  111.105-3, 
titled ``Approved Equipment.'' In the NPRM, we proposed to only combine 
Sec. Sec.  111.105-3 and 111.105-5 into Sec.  111.105-3, but this 
created confusion among commenters. We decided to also add Sec.  
111.105-7 into Sec.  111.105-3 to consolidate all the approved 
equipment regulations. The reason for this change is discussed 
previously in response to comments related to Sec.  111.105-3.
    We add 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 OCS facilities, vessels other than 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 incorporate these standards so 
that they are available to all vessels and facilities that must comply 
with subchapter J.
    In Sec.  111.105-11, we reduced the number of requirements listed 
here for intrinsically safe systems because the standards for these 
systems are now

[[Page 16339]]

contained in Sec.  111.105-3. Additionally, we are replacing ISA RP 
12.6-1995 in the existing Sec.  111.105-11(d) with the standard that 
supersedes it, ANSI/ISA 12.06.01-2003. This standard is now located in 
Sec.  111.105-11(b).
    In Sec.  111.105-7(a)(1)(i), we add ANSI/ISA 12.12.01 as a new 
standard for equipment in hazardous locations. See section VI.A for 
further explanation of this standard. In the NPRM, we also proposed 
incorporating UL 783 and ANSI/UL 2062 into this section. In the final 
rule, we have decided not to incorporate these standards by reference 
because they would have added electrical equipment requirements that 
were not already required for regulated vessels prior to this 
rulemaking. We would like to evaluate these standards and their effect 
on the industry more before considering them for incorporation by 
reference.
    In Sec.  111.105-17(b), we add IEC 61892-7:2019, IEC 60092-
502:1999, API RP 14, and API RP 14FZ as additional acceptable standards 
for the use of conduit. See section VI.A for further explanation of 
each standard.
    In the new Sec.  111.105-28, we add ASTM F2876-10 to address 
internal combustion engines in hazardous locations. Under the new 
section, internal combustion engines installed in Class I Divisions 1 
and 2 must 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 will 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 are providing the option for submerged 
cargo pumps that do not meet Sec.  111.105-31(d) to receive concept 
approval by the Commandant (CG-ENG) and plan approval by the Commanding 
Officer, MSC. This is consistent with existing Sec. Sec.  111.106-3(f) 
and 111.108-3(f).
    In Sec.  111.105-31(f), we delete references to IEEE 45 1998 and 
IEC 60092-502:1999 because they 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 clarify the requirements for systems 
installed in duct keels.
    In Sec. Sec.  111.105-35 and 111.105-45, we update the IEC 
classification notation in accordance with IEC 60079-10-2:2015.
    In Sec.  111.105-41, we remove 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 incorporate ANSI/ISA 12.12.01 as a 
new standard for equipment in hazardous locations. See section VI.A for 
further explanation of this standard. In the NPRM, we also proposed 
incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided 
not to incorporate these standards because they would add electrical 
equipment requirements that were not already required for regulated 
vessels prior to this rulemaking. We would like to evaluate these 
standards and their effect on the industry more before considering them 
for incorporation by reference.
Sec.  111.107-1 Industrial Systems
    In Sec.  111.107-1(b), we clarified the standards for switchgear. 
Currently Sec.  111.107-1(b)(1) refers to an unnecessarily broad range 
of standards. We 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 remove paragraph (b) from Sec.  111.108-1, which was 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 is no longer necessary because we 
include the same standards and systems in Sec.  111.108-3 (General 
requirements).
    In Sec.  111.108-3(b)(1)(i), we add ANSI/ISA 12.12.01 as a new 
standard for equipment in hazardous locations. See section VI.A for 
further explanation of this standard. In the NPRM, we also proposed 
incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided 
not to incorporate these standards because they would add electrical 
equipment requirements that were not already required for regulated 
vessels prior to this rulemaking. We would like to evaluate these 
standards and their effect on the industry more before considering them 
for incorporation by reference.
Sec.  112.01-20 Final Emergency Power Source
    We clarify the description of the final emergency power source in 
this section. For the convenience of the reader, we also cross-
reference Sec.  112.15-5, which specifies the existing regulations for 
final emergency power sources.
Sec.  112.05-5 Emergency Power Source
    In Sec.  112.05-5(a), we clarify that the emergency power source 
must be sized using a unity (1.0) service factor on all loads as 
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 
percent. 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 must be appropriately sized 
to accomplish this task.
Sec.  112.15-1 Temporary Emergency Loads
    In Sec.  112.15-1(s), we 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.
Sec.  112.43-13 Navigation Light Indicator Panel Supply
    We delete the requirement that the emergency light indicator panel 
be supplied directly from the emergency switchboard in this section. We 
made this change because Sec.  111.75-1(a) will no longer require that 
a feeder from the emergency generator directly supply the navigation 
light indicator panel supply and instead allow it to be supplied by an 
electrical panel, such as an emergency lighting panel, which is 
supplied by the emergency switchboard.
Sec.  112.50-1 General
    In Sec.  112.50-1(g), we delete the requirement that emergency 
generators automatically shut down upon loss of lubricating oil 
pressure. This section will 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

[[Page 16340]]

the crew to decide in an emergency situation if the emergency generator 
should be shut down. We also reformat Sec.  112.50-1(g) to clarify the 
remaining regulations for emergency generator set shut downs.
    In addition, we 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 non-substantive formatting edit that does not affect the 
existing alarm regulations for emergency generators in Sec.  112.50-
1(h).

VI. Incorporation by Reference

    Material that this rule incorporates by reference appears in Sec.  
110.10-1, and is summarized and discussed in section V.A of this 
preamble. Copies of the material are available either at the 
publisher's web address included in the regulatory text of Sec.  
110.10-1 or by contacting the publisher listed in the standard listed 
in Sec.  110.10-1. We also reviewed and updated all the publisher's web 
addresses listed in 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 to 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. The Director of the Federal 
Register approved the material in Sec.  110.10-1 for incorporation by 
reference under 5 U.S.C. 552 and 1 CFR part 51.

VII. Regulatory Analyses

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

A. Regulatory Planning and Review

    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.
    Details on the estimated cost savings of this rule can be found in 
the rule's RA that follows. This rule has not been designated by OMB a 
significant regulatory action under section 3(f) of Executive Order 
12866. Accordingly, OMB has not reviewed it.
    The Coast Guard received two public comments regarding the affected 
population in the RA for the proposed rule. We discuss our responses to 
these comments in section IV of the preamble of this final rule. We 
incorporated the commenters' suggestions into the RA for this final 
rule and revised the population of MODUs and Cargo and Miscellaneous 
Vessels based on MISLE data. We also updated the total population for 
the final rule (see table 4). In addition, we updated the mean hourly 
wage rate using 2021 data from the Bureau of Labor Statistics (BLS). As 
a result, we revised the estimated cost savings for this final rule. 
Table 2 summarizes the changes from the NPRM to the final rule and 
their expected impact on costs and cost savings. The changes we made to 
the respective CFR sections from the NPRM to the final rule, which we 
show in table 2, have no additional impact on the affected population 
or the cost savings we estimated in this analysis.

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

    With this final rule, the Coast Guard will update subchapter J of 
title 46 of the CFR to align the standards that 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 referenced in subchapter J. The provisions of this final 
rule will 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 will simply incorporate by reference 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 final rule to generate 
cost savings, from a reduction in equivalency requests, to industry and 
the Federal Government of approximately $209,352 over a 5-year period 
of analysis in 2021 dollars, using a 7-percent discount rate (we are 
using a 5-year period of analysis because we anticipate this final rule 
will not produce cost savings beyond this time period). We estimate 
annualized cost savings to be approximately $51,059, using a 7-percent 
discount rate. The cost savings are a result of industry submitting 
fewer equivalency requests to the Coast Guard (and the Coast Guard, 
therefore, needing to review fewer equivalency requests), and not from 
the changes to the IBR standards we make with this final rule. We 
expect the final rule to generate unquantified benefits because 
incorporating these standards will simplify regulatory compliance, 
reduce confusion, and provide industry flexibility. Table 3 provides a 
summary of the impacts of the final rule.

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

Affected Population
    This final rule affects 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 of title 46 of the CFR.\11\
---------------------------------------------------------------------------

    \11\ 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.
---------------------------------------------------------------------------

    We updated the affected population for the final rule because two 
years have elapsed since we collected the original data for the 
proposed rule. This final rule will affect approximately 5,602 existing 
inspected U.S.-flagged vessels. We obtained the affected population of 
this rule from our MISLE database. For standards we are incorporating 
by reference in this final 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 2020. 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.
    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 will generate cost 
savings by submitting fewer equivalency requests to the Coast

[[Page 16342]]

Guard. Included in the total population of 5,602 vessels are 1,460 new 
U.S.-flagged vessels that entered service in the last 8 years, from 
2014 to 2021. We divided 1,460 by 8 years to obtain an average of 
approximately 183 new U.S.-flagged vessels annually (see table 4 
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 an 18-month period from September 
2018 to February 2020. The Coast Guard received 10 equivalency requests 
annually from owners and operators of new vessels during this period. 
Prior to this time period, the Coast Guard did not collect data on 
equivalency requests.
    We expect this final rule will reduce the baseline number of 
equivalency requests the Coast Guard receives from industry by 80 
percent.\12\ We do not expect this final rule or any updates to 
standards to eliminate the public's questions altogether; although this 
rulemaking will update standards, we expect a certain number of 
standards to be out of date each year because standards organizations 
are continuously revising standards to reflect safety concerns or to 
maintain pace with technological advancements within the industry. 
Thus, we project that about 20 percent of the public still may have 
questions about the standards they are using annually during the 5-year 
period and expect the number of equivalency requests that we receive 
from the public to be about 20 percent of its current annual level. The 
Coast Guard makes a determination in the year we receive a question 
(equivalency request) from the public; therefore, the questions will 
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 final rule to reduce the number of 
questions by 80 percent in this year, which produces the cost savings. 
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 final 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 we expect 
standards organizations to have completed the process of updating all 
existing standards.
---------------------------------------------------------------------------

    \12\ Generally, standards are 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) will 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. We explain equivalency 
requests in greater detail in the Cost Savings Analysis portion of this 
RA.

    This 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 final 
rule will 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 final rule will encourage the use 
of newer equipment and promote adherence to modern standards in the 
industry. Industry also will realize cost savings from not having to 
send equivalency requests to the Coast Guard. See table 4 for how parts 
of the CFR will be affected by this final rule along with the 
anticipated impacts.
Benefits of the Rule
Cost Savings Analysis
    We divided all of the changes of this final rule into three 
categories, which

[[Page 16343]]

we present in table 5: (1) Editorial changes to the CFR, (2) updates to 
IBR standards with technical changes, and (3) IBR standards with 
incorporated options or alternative options. The changes we make to the 
standards incorporated by reference in this final rule will not result 
in costs or cost savings to industry.
    First, we will 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 update IBR standards 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 several years and all of which have been 
developed by standard-based development organizations. These more 
recent standards, which this final rule adopts, provide greater clarity 
and specificity than the outdated technical standards they are 
replacing; therefore, we expect these changes to be a no cost change.
    Third, for IBR standards that are one of several available 
standards as referenced in subchapter J, we update standards with a 
more recent edition (these will 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. The combination of these options will provide 
industry the opportunity to remove overly prescriptive requirements, 
simplify regulatory compliance, and provide regulatory flexibility. 
Many of the options, some of which are alternative options and others 
of which are new, are IBR standards that affect multiple subparts of 46 
CFR parts 110, 111, and 113. The remaining options are not IBR 
standards and affect multiple subparts of 46 CFR parts 111 and 112. The 
options we incorporate by reference apply to the same population of 
5,602 vessels. We assume industry will use the more recent national and 
international standards referenced in this rule. We expect adding a 
revised or new standard, which represents a more recent standard 
industry that is currently using, as an additional option to the 
existing standards will be a no cost change because these standards are 
not requirements; industry can instead choose a given standard to use 
among different alternative options. See table 5.
    Specifically, we adopt 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 category (IBR standards with technical changes), 
while electrical cable construction, emergency generator, and hazardous 
locations fall primarily into the third category (IBR standards with 
proposed and alternative options), which we listed previously.
Generator Prime Mover
    This final rule eliminates 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 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 will 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, 
this final rule incorporates 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 final rule also aligns 
electrical cable standards in subpart 111.60 with standards accepted 
internationally by vessel classification societies and foreign 
administrations and removes unnecessary, prescriptive requirements 
developed by the Coast Guard, which in turn, will simplify compliance. 
We expect this to be a no cost change because electrical cables are 
readily available that meet the standards that we incorporate by 
reference with this final rule.
Hazardous Locations
    This final rule amends 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 or no cost savings change.
Emergency Generator
    This final rule amends 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 fewer exhaust 
emissions than using the ship's larger service generators. This option 
is consistent with international guidance and classification society 
rules. However, this option applies to a very small number of U.S.-
flagged vessel owners and operators who request it, and the Coast Guard 
will 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 uses less fuel than a ship's main 
generator.
    This final rule creates consistency between Coast Guard regulations 
and national and international standards through incorporation by 
reference, provides options with alternative standards, eliminates 
obsolete standards, and clarifies the existing requirements through the 
changes we adopt in 46 CFR subchapter J. We categorize these changes in 
table 5, which summarizes the impacts of this final rule and the 
affected parts and subparts in subchapter J. Consistent with DHS 
practice, table 5 specifically lists all of the individual changes by 
part, subpart, and paragraph of 46 CFR subchapter J. Table 1 in section 
II of the preamble is a general summary of the changes in subchapter J.

  industry standards'' means equipment manufacturers have been constructing equipment to the more recent
  editions of standards.

    The Coast Guard evaluated the affected population and estimates 
that this final rule will generate cost savings for owners and 
operators of new U.S.-flagged vessels who will no longer submit 
equivalency requests to the MSC for review. This final rule will also 
generate cost savings for the Federal Government, which will review 
fewer equivalency 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, an owner 
or operator makes such a request 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, an 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 46 CFR 
subchapter J. A Coast Guard Marine Engineer compares the 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 compare 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 they will not likely 
request an equivalency review from the Coast Guard following this rule. 
However, the Coast Guard expects owners and operators of new U.S.-
flagged vessels that enter service each year to nevertheless have some 
equivalency questions because they may not be familiar with all of the 
applicable regulations in subchapter J, which include 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 for which the Coast Guard maintained equivalency data. 
This is equivalent to 10 requests annually (15 requests / 18 months x 
12 months = 10 requests). We did not receive any public comments 
concerning this estimate; therefore, we retain the estimate of about 10 
requests annually for the final rule. MSC data, validated by CG-ENG, 
show that a vessel owner or operator typically submits no more than one 
equivalency request in a given year, no matter how many vessels they 
may own or operate. 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, creates 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 will 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 generates equivalency requests on an 
annual basis; we do not expect a published rule to eliminate the 
public's questions altogether.
Industry Baseline Costs
    Without this final rule or under the current baseline, the Coast 
Guard receives approximately 10 equivalency requests annually, as we 
discussed previously. To draft an equivalency request to the MSC, an 
owner or operator of a U.S.-flagged vessel seeks the services of an 
engineering design firm or a shipyard's technical staff for a Marine 
Engineer or Naval Architect. Using the BLS ``Occupational and 
Employment Statistics'' database and May 2021 wage estimates, the 
unloaded mean hourly wage rate for Marine Engineers and Naval 
Architects is $47.03 (occupational code 17-2121).\13\ To account for an 
employee's non-wage benefits, we apply a load factor to the unloaded 
mean hourly wage rate, which we calculated by using BLS's ``Employer 
Cost for Employee Compensation''

[[Page 16346]]

database. We determined the load factor to be approximately 1.48, 
rounded.\14\ We multiply $47.03 by 1.48 to obtain a loaded mean hourly 
wage rate of approximately $69.60 for this occupation.

    \14\ 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 second 
quarter data for 2021, we divided the value for total compensation, 
$31.90, by wages and salaries, or $21.54, to obtain a load factor of 
about 1.48, rounded. https://data.bls.gov/cgi-bin/dsrv?cm.
---------------------------------------------------------------------------

    Based on information from the MSC and validated by subject matter 
experts in CG-ENG, 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 $27,840, or $2,784 
for each request (10 equivalency requests x $69.60 x 40 hours per 
request). See table 6 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 is equivalent to 
a standard found in subchapter J. Based on information from the MSC and 
validated by subject matter experts in CG-ENG, a civilian Coast Guard 
Marine Engineer needs about 32 hours to review an equivalency request. 
Based on 10 requests received annually, the Coast Guard expends 
approximately 320 hours annually to review these requests. A Coast 
Guard Marine Engineer typically has a Federal Government General 
Schedule (GS) grade level of GS-14. The Office of Personnel Management 
lists the hourly pay for Federal employees who work in the Washington, 
DC area on its website, and records the hourly pay of a person with the 
grade level of a GS-14, step 5 (the midpoint of the pay grade) as 
$66.54.\15\ We then calculate the share of total compensation of 
Federal employees to account for a Government employee's non-wage 
benefits. The Congressional Budget Office reports total compensation to 
Federal employees to be $64.80 per hour and wages to be $38.30.\16\ We 
determine the load factor to be approximately 1.69 ($64.80 / $38.30). 
We multiply $66.54 by 1.69 to obtain a loaded hourly wage rate of 
approximately $112.45 for a GS-14 Senior Engineer (Marine Engineer or 
Naval Architect). We estimate the total, undiscounted cost for the 
Federal Government to review 10 equivalency requests annually to be 
approximately $35,984 (10 equivalency requests x 32 hours for each 
request x $112.45), or $3,598 for each request. See table 7 for the 
Federal Government inputs.

    We estimate the total, undiscounted baseline cost to industry and 
the Federal Government to submit and review equivalency requests, 
respectively, to be approximately $63,824 ($27,840 + $35,984), 
annually. Table 8 presents a summary of the baseline costs associated 
with industry submitting equivalency requests to the Coast Guard.

Industry Cost Savings
    The baseline costs we estimate for industry is from vessel owners 
and operators of new U.S.-flagged vessels that enter service each year 
who submit equivalency requests. We expect this rule will reduce the 
number of equivalency requests industry submits annually. We estimate 
195 companies own the average number of 183 new U.S.-flagged vessels 
that have entered service each year in the past 8 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 
will 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 will 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 will not affect or change an existing 
information collection request, nor will it create a new one, because 
we estimate the number of requests to be approximately 2 annually, 
which is below the threshold of 10 limit set by the Paperwork Reduction 
Act of 1995 (44 U.S.C. 3501-3520). The Federal Government does not 
require the marine industry to submit these requests; vessel owners and 
operators (or manufacturers) voluntarily submit requests only if they 
have questions about the standards they are using.

[[Page 16347]]

    Using the same labor category previously used to calculate the 
baseline for industry costs, we estimate the total undiscounted cost 
savings of this rule to industry to be approximately $22,272 annually 
[(10 equivalency requests x 40 hours for each equivalency x $69.60 = 
$27,840) minus (2 equivalency requests x 40 hours for each equivalency 
request x $69.60 = $5,568)]. We estimate 5-year cost savings of this 
rule to industry to be approximately $91,320, using a 7-percent 
discount rate. We estimate the annualized cost savings to be 
approximately $22,272, using a 7-percent discount rate, as shown in 
table 9.

Federal Government Cost Savings
    With this final rule, we expect the Coast Guard will review 
annually 2 equivalency requests (10 equivalency requests x 0.20). This 
again will be a reduction of 80 percent from the baseline number of 10 
requests. With fewer equivalencies to review, the Coast Guard will 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 this final rule to the Federal Government to be 
approximately $28,787 annually [(10 baseline equivalency requests x 32 
hours for each equivalency request x $112.45 = $35,984) minus (2 
equivalency requests x 32 hours for each equivalency request x $112.45 
= $7,197)]. We estimate the 5-year discounted cost savings of this rule 
to the Federal Government to be approximately $118,032, using a 7-
percent discount rate. We estimate the annualized cost savings to be 
approximately $28,787, using a 7-percent discount rate, as shown in 
table 10.

Total Cost Savings of This Rule
    We estimate the 5-year, total discounted cost savings of this final 
rule to be approximately $209,352 ($91,320 + $118,032), using a 7-
percent discount rate. We estimate the annualized cost savings of this 
rule to be approximately $51,059, using a 7-percent discount rate. The 
total annualized cost savings is the summation of the values in tables 
9 and 10 ($22,272 + $28,787 = $51,059) as a result of the reduction in 
the number of equivalency requests we expect annually from industry, as 
shown in table 11.

Unquantified Cost Savings of the Final Rule
    We expect this final rule will have unquantified cost savings 
associated with the option of using an emergency generator while in 
port. The use of an emergency generator in port will likely save fuel 
because it does 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 will 
choose this option while in port. Nevertheless, we expect at least a 
small number of vessel owners and operators to choose this option.
    Additionally, we expect this final rule to generate qualitative 
benefits. This final rule is necessary because it will 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 will 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 will be new options. 
With these changes, industry will follow less ambiguous regulatory 
provisions, which we expect will create fewer equivalency requests. In 
addition, we removed Coast Guard prescriptive requirements in some 
places and replaced them with more recent national or international 
standards, which should simplify compliance.
    Regarding the use of an emergency generator while in port, this 
option will 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 fewer 
exhaust emissions than using the larger ship's service generators. This 
will 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 will 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 to predict how many 
vessel owners and operators will choose this option while in port due 
to the lack of data. The Coast Guard did not receive any public 
comments on the proposed rule concerning cost or cost savings 
associated with the use of an emergency generator and exhaust emissions 
while a vessel is in port.
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 the 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 subchapter J would still contain outdated 
standards and overly 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 $22,272 annually (undiscounted). We 
estimate the 5-year discounted cost savings of this alternative to 
industry would be approximately $91,320, using a 7-percent discount 
rate. We estimate the annualized cost savings would be approximately 
$22,272, 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

[[Page 16349]]

editorial changes to reduce the ambiguity that currently exists.
    With this alternative, we will update the current standards in 46 
CFR subchapter J and incorporate the more recent industry standards. 
This is the preferred alternative because it will 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.
    This alternative will 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 will also reduce the 
hours the marine industry will spend on drafting and submitting 
equivalency requests to the Coast Guard. We analyzed and presented the 
cost saving impacts of this alternative to industry and the Coast Guard 
earlier in this RA.

B. Small Entities

    Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 601-612) 
(RFA), we have considered whether this final 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 rule creates cost savings for industry because we estimate 
fewer equivalency requests will 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 an 8-year period from 2014-2021, 
we found 1,460 new U.S.-flagged vessels entered service, or an average 
of approximately 183 annually during this period. We found that 195 
companies owned the 1,460 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 119 of the 195 
companies, or approximately 61 percent.\17\ Using the Small Business 
Administration's ``Table of Size Standards'' and the North American 
Industry Classification System codes listed in the table, we found 88 
of the 119 companies to be small entities.\18\ We found the other 31 
companies to be not small.\19\ We did not find information on the 
remaining 76 companies; therefore, we assumed these companies to be 
small entities for a total of 164 small entities out of 195 companies, 
or approximately 84 percent.
---------------------------------------------------------------------------

    \17\ http://www.referenceusagov.com.
    \18\ The Coast Guard was unable to find revenue information for 
two of these small entities.
    \19\ https://www.sba.gov/document/support--table-size-standards.
---------------------------------------------------------------------------

    We analyzed the potential economic impacts of this final rule on 
small entities and found that each small entity that no longer submits 
an equivalency request will save approximately $2,784 annually. We 
estimate an 80 percent reduction in the number of equivalency requests 
(from 10 to 2 annually) industry submits to the Coast Guard with this 
rule; therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that 
this final rule will not have a significant economic impact on a 
substantial number of small entities.
    Any small entity that does not submit an equivalency request will 
not be impacted by any costs or cost savings.

C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement 
Fairness Act of 1996 (Pub. L. 104-121), we offer to assist small 
entities in understanding this rule so that they can better evaluate 
its effects on them and participate in the rulemaking. The Coast Guard 
will not retaliate against small entities that question or complain 
about this rule or any policy or action of the Coast Guard.
    Small businesses may send comments on the actions of Federal 
employees who enforce, or otherwise determine compliance with, Federal 
regulations to the Small Business and Agriculture Regulatory 
Enforcement Ombudsman and the Regional Small Business Regulatory 
Fairness Boards. The Ombudsman evaluates these actions annually and 
rates each agency's responsiveness to small business. If you wish to 
comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR 
(1-888-734-3247).

D. Collection of Information

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires 
the U.S. Coast Guard to consider the impact of paperwork and other 
information collection burdens imposed on the public. The Coast Guard 
has determined that there will be no new requirement for the collection 
of information associated with this final rule.

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 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), as well as 
the reporting of casualties and any other category in which Congress 
intended the Coast Guard to be the sole source of a vessel's 
obligations, are within the field foreclosed from regulation by the 
States. See United States v. Locke, 529 U.S. 89, 115-116 (2000) 
(holding that Congress intended that the Coast Guard regulations be the 
sole source of vessel design, operation, and reporting requirements). 
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 categories, this rule is consistent with the fundamental 
federalism principles and preemption requirements described in 
Executive Order 13132.

F. Unfunded Mandates

    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 Unfunded Mandates Reform Act 
addresses actions that may result in the expenditure by a State, local, 
or tribal government, in the aggregate, or by the private sector of 
$100,000,000 (adjusted for inflation) or more in any one year. Although 
this rule will not result in such expenditure, we discuss the effects 
of this rule elsewhere in this preamble.

[[Page 16350]]

G. Taking of Private Property

    This rule will 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 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 rule under Executive Order 13045 (Protection 
of Children from Environmental Health Risks and Safety Risks). This 
rule is not an economically significant rule and will not create an 
environmental risk to health or risk to safety that might 
disproportionately affect children.

J. Indian Tribal Governments

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

K. Energy Effects

    We have analyzed this rule under 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 and Incorporation by Reference

    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 rule uses the following voluntary consensus standards:

M. Environment

    We have analyzed this rule under Department of Homeland Security 
Management Directive 023-01, Rev. 1, associated implementing 
instructions, and Environmental Planning COMDTINST 5090.1 (series), 
which guide the Coast Guard in complying with the National 
Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made 
a determination that this action is one of a category of actions that 
do not individually or cumulatively have a significant effect on the 
human environment. A 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 
rule is categorically excluded under paragraphs L54 and L57 of Appendix 
A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 01. Paragraph 
L54 pertains to regulations that are editorial or procedural. Paragraph 
L57 pertains to regulations concerning manning, documentation, 
admeasurement, inspection, and equipping of vessels.
    This rule involves incorporating by reference several updated 
electrical engineering standards along with removing several outdated 
or unnecessarily prescriptive electrical engineering regulations.

Subpart 111.51--Calculation of Short-Circuit Currents and 
Coordination of Overcurrent Protective Devices

Sec.  111.51-1  General.

    Electrical installations must be protected against short circuits, 
by appropriate devices. The selection, arrangement and performance of 
various protective devices must provide coordinated automatic 
protection and selective operation in order to provide continuity of 
service for equipment vital to the propulsion, control, or safety of 
the vessel under short-circuit conditions through coordination and 
selective operation of overcurrent protective devices.

Sec.  111.51-2  Short-circuit calculations.

    (a) The available short-circuit current must be computed--
    (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 
kilowatts.

    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 
aggregate normal rated generator currents plus 3\1/2\ times the 
aggregate normal rated currents of all motors that may be in operation.

Sec.  111.51-4  Short-circuit calculations for systems 1500 kilowatts 
or above.

    Short-circuit calculations must be submitted for systems with an 
aggregate generating capacity of 1500 kilowatts or more by utilizing 
one of the following methods:
    (a) Exact calculations using actual impedance and reactance values 
of system components.
    (b) Estimated calculations using IEC 61363-1:1998 for AC systems 
and IEC 61660-1:1997 for DC systems (both incorporated by reference; 
see Sec.  110.10-1 of this subchapter).
    (c) The estimated calculations using a commercially established 
analysis procedure for utility or industrial applications.

[[Page 16363]]

Sec.  111.51-5  Protection of vital equipment.

    (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.
