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outdated or unnecessarily prescriptive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

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

optional capability to use emergency
generators in port is acceptable if a set

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

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

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.

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 § 110.01–
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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

Subpart 110.01—Applicability
§ 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 § 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 § 110.01–3(b), alterations and
modifications, such as re-engining, repowering, 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 § 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
§ 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 § 110.10–1.
Several commenters suggested
incorporating by reference newer
editions than we had proposed to
incorporate in § 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
E:\FR\FM\16MRR2.SGM
16MRR2
ddrumheller on DSK120RN23PROD with RULES2
Federal Register / Vol. 88, No. 51 / Thursday, March 16, 2023 / Rules and Regulations
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
§ 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, § 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/
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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
§§ 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 § 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 § 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
§ 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
§ 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
§ 110.25–1 Plans and Information
Required for New Construction
A commenter noted that the proposed
changes to § 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 § 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 § 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 § 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
§ 111.10–9 Ship’s Service Supply
Transformers; Two Required
A commenter noted that our proposed
revision to the note to § 111.10–09
concerning ship’s service transformers
appears to contradict the text of
§ 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
§ 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

Construction and Circuits
ddrumheller on DSK120RN23PROD with RULES2
§ 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 airconditioned 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 leadacid 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
2 NVIC 2–89, ‘‘Guide for Electrical Installations
on Merchant Vessels and Mobile Offshore Drilling
Units,’’ is available at https://www.dco.uscg.mil/

consider it in a future rulemaking.
Further, we find that we cannot include

111.30.
Subpart 111.30—Switchboards
§ 111.30–25 Alternating-Current Ship’s
Service Switchboards
§ 111.30–5 Construction
In the NPRM, we proposed replacing
the existing reference to section 8.3 of
IEEE 45–2002 in § 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 § 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
§ 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 § 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 § 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

§ 111.30–19
Buses and Wiring
In the NPRM, we proposed replacing
the existing reference to section 7.10 of
IEEE 45–1998 in § 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.
A commenter suggested that the
generator field rheostat (manual voltage
controller) currently required by
§ 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 § 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
E:\FR\FM\16MRR2.SGM
16MRR2
Federal Register / Vol. 88, No. 51 / Thursday, March 16, 2023 / Rules and Regulations
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 §§ 111.33–1 and 111.33–3(b).
Subpart 111.40—Panelboards
§ 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 § 111.40–1 in this rule to only
reference subsection 9.10.1.

Subpart 111.50—Overcurrent Protection
§ 111.50–3 Protection of Conductors
A commenter noted that currently
neither § 111.50–3 nor § 111.20–15
clearly addresses NFPA 70—National
Electric Code (NEC) requirements for
transformer secondary conductor
protection and suggested that § 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
§ 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 § 111.50–3 in the future.
A commenter also said that neither
§ 111.50–3 nor § 58.25 currently address
DC steering gear motors. The commenter
also said that both §§ 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 § 111.50–3 to align
with ABS SVR 4–8–2/9.17.5 standards
on DC steering gear motors and
VerDate Sep<11>2014

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
§ 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 § 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
§§ 111.51–1 Purpose and 111.51–5
Protection of Vital Equipment
In the NPRM, we proposed to revise
§ 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 § 111.51–1
that it replaced. A commenter noted the
term ‘‘continuity of service’’ as used in
the proposed revisions to § 111.51–1, as
well as in the current text of § 111.51–
1, is not defined and could be
interpreted in a number of ways.
Additionally, the same commenter also
recommended editing § 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 §§ 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 § 110.20–1. We
made no changes from the proposed
rule in § 111.51–5.
Subpart 111.60—Wiring Materials and
Methods
§ 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 § 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 costprohibitive to meet the fire test
requirements. The commenter
recommended retaining § 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
§ 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
§ 111.60–3. We will consider other cable
on a case-by-case basis in accordance
with the equivalency provisions of
§ 110.20–1.
§ 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 (mm2) and
2.1 mm2 for control and power cable,
respectively. The commenter explained
that vessels inspected under the ACP
E:\FR\FM\16MRR2.SGM
16MRR2
16316
Federal Register / Vol. 88, No. 51 / Thursday, March 16, 2023 / Rules and Regulations
have a lesser conductor size
requirement. For example, ABS MVR 4–
8–2/7.7.2 allows smaller minimum
conductor sizes of 0.5 mm2 and 1.5 mm2
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.

Fiber Optic Cable (Existing)
In the NPRM, we proposed to remove
current § 111.60–6 because fiber optic
cable that complies with § 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 § 111.60–1 and have
decided to forgo the proposed change to
remove §§ 111.60–2 and 111.60–6. This
final rule does not remove existing
§§ 111.60–2 and 111.60–6, or the cross
references to §§ 111.60–2 and 111.60–6
within the applicable list of standards
incorporated by reference in §§ 110.10–

conform with updates to standards
incorporated by reference within this

Wire
A commenter noted the reference to
Section 5.7 of IEEE 45.8–2016 in
§ 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 § 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
§ 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
§§ 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 §§ 111.70–3(c)(2) and
(d)(1)(v).
Subpart 111.75—Lighting Circuits and
Protection
§ 111.75–17
Navigation Lights
In the NPRM, we proposed
incorporating EN 14744 in § 111.75–17
as an additional alternative standard for
navigation lights. Currently, UL 1104 is
the only standard incorporated by
reference in § 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
PO 00000
Frm 00008
Fmt 4701
Sfmt 4700
(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 noninspected 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.

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
§ 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
§ 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
§ 111.99–5
General
The NPRM proposed updating the
existing citation in § 111.99–5 to reflect
a more current edition of the
International Convention for Safety of
Life at Sea, 1974 (SOLAS), Sixth
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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 § 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.
§ 111.105–3 General Requirements and
System Integrity
The intent of § 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
PO 00000
Frm 00009
Fmt 4701
Sfmt 4700
16317
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 §§ 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
§ 111.105–3(c). Additionally,
commenters suggested that we
reorganize § 111.105–3 to better separate
equipment selection standards and
installation requirements. Since its
initial adoption in 1996, our intentions
in § 111.105–5 (which we had proposed
to move into § 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
§ 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.
In the NPRM we proposed to combine
§§ 111.105–3 and 111.105–5 into
§ 111.105–3 to be consistent with
§§ 111.106–3 and 111.108–3. This
created confusion among commenters,
and we have decided to revise our
approach to proposed § 111.105–3.
Instead, we have renumbered the
proposed § 111.105–7 as § 111.105–3
and amended it to be more consistent
with §§ 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 Divisiondesignated spaces or using Division
equipment in Zone-designated spaces.

Additionally, as mentioned earlier, we
will also require in § 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 § 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 § 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 § 111.108(a)(3). It was not our
goal for the proposed modifications to
§ 111.105 to substantively change the
standards fundamental to equipment
selection. In the existing regulations, in
accordance with § 111.108–1(b), all
vessels could use the standards
specified in 46 CFR Subpart § 111.108.
Revisions to § 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 § 111.105–3. The requirements for
wiring and cable systems in hazardous
locations are in § 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–
VerDate Sep<11>2014

Jkt 259001
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
§ 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.
§ 111.105–28 Internal Combustion
Engines
A commenter said that § 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,
§ 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
§ 111.108–3(g). Our purpose in changing
§ 111.105 is to improve the consistency
of the regulations related to hazardous
areas in §§ 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
PO 00000
Frm 00010
Fmt 4701
Sfmt 4700
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.
§ 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.
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
§§ 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 §§ 32.60–20(c) and 38.20–10,

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 § 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
§ 112.05–5
Emergency Power Source
ddrumheller on DSK120RN23PROD with RULES2
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 § 112.05–5 footnote 2, we
are replacing the reference to § 111.93
with a reference to § 58.25–65 because
we moved the requirements in § 111.93
to § 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.
§ 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
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
procedure (PSTP) be submitted for
review, but the proposed § 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 § 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 § 112.05–7.
A commenter said we could require
more comprehensive alarms in
§ 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 § 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 § 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 § 112.05–3(c) and
the new § 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 § 112.05–7(e) appeared to be
PO 00000
Frm 00011
Fmt 4701
Sfmt 4700
16319
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 § 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 § 112.05–7.
Subpart 112.15—Emergency Loads
§ 112.15–1 Temporary Emergency
Loads
As provided in the NPRM, in
§ 112.15–1 we will now require an
engineer’s assistance-needed alarm as a

ddrumheller on DSK120RN23PROD with RULES2
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 § 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
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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 § 110.10–1
Incorporation by Reference
The standards that are incorporated
by reference in subchapter J are listed in
§ 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 § 110.20–1.
Throughout § 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 § 110.10–1. Within each
standard listed, we describe the topics

• 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
§§ 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 § 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

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:
Æ ABS MOU Rules 4–3–4 (renamed

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
§ 111.108–3(b) as part of a separate
rulemaking titled ‘‘Electrical Equipment
in Hazardous Locations’’ (80 FR 16980,
Mar. 31, 2015). Additionally, we

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 § 111.106–3(d), and the
2012 edition in § 111.108–3(e). This rule
removes the ANSI/ISA–60079–18
references in §§ 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
§ 111.106–3(d) and 111.108–3(e).

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

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.

for calculating 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 § 111.52–5. This rule
will move the standard to the new
§ 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).

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
§ 111.105–7, which we are merging into
§ 111.105–3. We also include § 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:
Æ 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.
Æ 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.
Æ 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.
Æ 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.
Æ Article 314—This article on outlet
or junction boxes has several minor
updates based on changes in technology
or industry practices.
Æ 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.
Æ 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.
Æ Article 404—The applicability of
this article on switches has been raised
from 600 V systems to 1000 V systems,
PO 00000

and several additional switch types
have been added.
Æ 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.
Æ 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.
Æ Article 504—Sections 504.10,
504.30, 504.50 and 504.60 on
intrinsically safe system design will be
added in § 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 § 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 § 111.105–37. By means
of this rule, we instead reference the

been an industry standard for purged
and pressurized enclosures since 1971.
We currently reference the 2003 edition
of this standard in § 111.105–7, the 2008
edition is currently referenced in
§ 111.106–3(c), and the 2013 edition is
currently referenced in § 111.108–3(d).
By means of this rule, we update the
references to the more recent 2017
edition in §§ 111.105–3 (formerly
§ 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
§ 111.52–5. We reorganize the
requirements for short-circuit
calculations for systems 1500 kW or
above in § 111.52–5 into new § 111.51–
4. The other three options that are
currently in § 111.51–4 are still
included in the new § 111.51–4.
• MIL–HDBK–299(SH), 1991—

also provides guidance for their design,
handling, installation, and maintenance.
This current edition is referenced in
§ 111.60–3 regarding cable applications.
By means of this rule, we delete this
standard because we are also rescinding
§ 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 § 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

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

locations. We currently reference the
third edition (2000) of this standard in
§ 111.105–9 and the fourth edition
(2006) in §§ 111.106–3(b) and 111.108–
3(b). By means of this rule, we reference
the more recent fifth edition (2015) in
§ 111.105–3(b) instead of § 111.105–9
due to editorial reformatting of subpart
111.105, as well as §§ 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

petroleum facilities, and MODUs. We
currently reference the first edition
(1995) of this standard in §§ 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
§§ 111.60–1 and 111.106–5(a) because
we delete § 111.60–3. The standard has
received updates to its construction,
performance, ratings, and markings
requirements.
• UL 1581—Standard for Safety

• 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 § 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

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 § 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 nonsubstantive 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 § 111.108–3(b) for standards
on electrical equipment in hazardous
locations. By means of this rule, we
delete this standard from § 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 § 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
§ 111.87–3(a).

Jkt 259001
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
§ 111.106–3(b) and the third edition
(2011) of this standard in § 111.108–
3(b). By means of this rule, we reference
the more recent fourth edition (2013) in
§§ 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-todate 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 §§ 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 §§ 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 §§ 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.
PO 00000
Frm 00027
Fmt 4701
Sfmt 4700
16335
The ABS Steel Vessel Rules, which are
already incorporated by reference in
§ 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 § 111.12–1, and
we find that the requirements in the
incorporation by reference sufficiently
address the concerns that § 111.12–1(b)
and (c) were intended to address.
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
§ 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 §§ 111.60–3 and
111.60–4.
We also are rescinding § 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 § 111.60–1, as revised by this rule, for
the application of specific types of
cable.
In § 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 § 111.60–19
refer to IEEE 45’s recommendations for
cable splices.
6 We note that § 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
§ 58.01 to the 2020 edition of the ABS Marine
Vessel Rules.. This is the same edition incorporated
by reference in § 110.10–1(a). If we amend § 58.01
through a final rule on this same topic, any changes
made would not conflict with the intent of
§ 111.12–1. Generator prime movers will have to
meet the ABS Marine Vessel Rules incorporated by
reference in § 58.01.

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 § 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
§ 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 § 111.105–
50. New section 111.105–50(a) contains
an alternative standard for the
classification of hazardous locations
requirements in §§ 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.
In § 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 § 112.05–7. The current
regulations in § 112.05–1 require that
the emergency source of power must be
dependable, independent, and
dedicated. The purpose of these
requirements in § 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
Coast-Guard-Regulatory-Development-ProgramRDP-/Alternate-Compliance-Program/.
PO 00000
Frm 00028
Fmt 4701
Sfmt 4700
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 § 112.05–7 are similar to
those prescribed in MSC.1/Circ.1464/
Rev.1 as well as section 4–8–2/5.17 of
the ABS Marine Vessel Rules.

F. Description of Additional Changes
Within Subchapter J 8
§ 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
§ 111.10–1(a) to § 110.15–1 so that all
definitions for subpart J are in one
location.
§ 110.25–1 Plans and Information
Required for New Construction
We have consolidated the hazardous
locations plan submittal requirements of
the existing § 110.25–1(i), (p), and (q)
into a single section, § 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, §§ 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 § 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.

§ 111.05–3 Design, Construction, and
Installation; General
In § 111.05–3(c), we clarify the
grounding requirements for appliances
and tools so that the requirements are
consistent with current industry
practice.
§ 111.10–9 Ship’s Service Supply
Transformers; Two Required
This rule revises the note to § 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

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 § 111.87–3 because, following the
addition of a new standard as discussed elsewhere
in this rule, ‘‘both’’ was no longer an accurate
description.

§ 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.
§ 111.12–13 Propulsion Generator
Protection
We are deleting this section on
propulsion generator protection because
it is simply a reference to § 111.35–1.
This cross-reference is not necessary.
§ 111.15–10 Ventilation
In § 111.15–10(b)(2)(i), we add the IEC
equivalent classification of Class I,
Division 1, Group B as an alternate
standard.
§ 111.25–5 Marking
Under § 111.25–1, motors are required
to meet the requirements for generators
in § 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.
§ 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 § 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 § 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 § 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).
§ 111.50–3
Protection of Conductors
In § 111.50–3(b)(2), we revise the
requirement for steering gear circuits
from subchapter F to a more specific
cite of § 58.25. We also remove the
reference to IEC 92–202 from § 111.50–
3(c). This standard does not address
standard ratings for fuses or circuit
breakers.
Subpart 111.51 Calculation of ShortCircuit 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
§ 111.51–1 is based on IEC 60092–
202:2016.
The short-circuit calculations
requirements of new § 111.51–2(a) are
from the existing § 111.52–1. The new
§ 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 §§ 111.51–3
and 111.51–5 are from the existing
§§ 111.52–3 and 111.52–5, respectively.
We are deleting NAVSEA DDS 300–2
from the existing § 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, § 111.51–6, are from
the existing § 111.51–3.

§ 111.54–1 Circuit Breakers
In § 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.
§ 111.75–17 Navigation Lights
In § 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 § 112.43–13,
which provided details on the
navigation light panel feeder.
In § 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 § 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.
Additionally in § 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 § 111.75–
17(d)(4) because this requirement is
contained in section 22.11 of UL 1104
and section 4.4 of EN 14744.
§ 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.
§ 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.
§ 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.
§ 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 § 111.99. Now § 111.99–
5 requires fire door holding and release
systems, if fitted, to meet SOLAS II–2/
9.4.1.1.5.3. Previously, § 111.99–5
required these systems to meet SOLAS
II–2/30.4.3, but we have updated this

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 §§ 111.105–3, 111.105–5, and
111.105–7 into one revised section,
§ 111.105–3, titled ‘‘Approved
Equipment.’’ In the NPRM, we proposed
to only combine §§ 111.105–3 and
111.105–5 into § 111.105–3, but this
created confusion among commenters.
We decided to also add § 111.105–7 into
§ 111.105–3 to consolidate all the
approved equipment regulations. The
reason for this change is discussed
previously in response to comments
related to § 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 § 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 § 111.105–11, we reduced the
number of requirements listed here for
intrinsically safe systems because the
standards for these systems are now

we are replacing ISA RP 12.6–1995 in
the existing § 111.105–11(d) with the
standard that supersedes it, ANSI/ISA
12.06.01–2003. This standard is now
located in § 111.105–11(b).
In § 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 § 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 § 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 § 111.105–28. This will ensure a
consistent standard for these
installations on all vessel and facility
types.
In § 111.105–31(e), we are providing
the option for submerged cargo pumps
that do not meet § 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
§§ 111.106–3(f) and 111.108–3(f).
In § 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 § 111.105–31(o), we clarify the
requirements for systems installed in
duct keels.
In §§ 111.105–35 and 111.105–45, we
update the IEC classification notation in
accordance with IEC 60079–10–2:2015.
In § 111.105–41, we remove the
reference to IEEE 45 1998 because the
standard has been superseded.

In § 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

§ 111.107–1
Industrial Systems
In § 111.107–1(b), we clarified the
standards for switchgear. Currently
§ 111.107–1(b)(1) refers to an
unnecessarily broad range of standards.
We simplify this section by crossreferencing 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
§ 111.108–1, which was a crossreference 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 crossreference to subpart 111.105 is no longer
necessary because we include the same
standards and systems in § 111.108–3
(General requirements).
In § 111.108–3(b)(1)(i), we add ANSI/
ISA 12.12.01 as a new standard for

§ 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 § 112.15–5, which
specifies the existing regulations for
final emergency power sources.
§ 112.05–5 Emergency Power Source
In § 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.
§ 112.15–1 Temporary Emergency
Loads
In § 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 § 113.27–1(c) that states
it must be powered from the same
source as the general alarm.
§ 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 § 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.
§ 112.50–1 General
In § 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

situation if the emergency generator
should be shut down. We also reformat
§ 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 § 112.50–1(h).
VI. Incorporation by Reference
Material that this rule incorporates by
reference appears in § 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 § 110.10–1 or by
contacting the publisher listed in the
standard listed in § 110.10–1. We also
reviewed and updated all the
publisher’s web addresses listed in
§ 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 § 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

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
arrangements in one of the subchapters previously
listed.

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

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 5year 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.
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.
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.

Benefits of the Rule
Cost Savings Analysis
We divided all of the changes of this
final rule into three categories, which
E:\FR\FM\16MRR2.SGM
16MRR2
ddrumheller on DSK120RN23PROD with RULES2
Federal Register / Vol. 88, No. 51 / Thursday, March 16, 2023 / Rules and Regulations
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
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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 § 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 § 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
PO 00000
Frm 00035
Fmt 4701
Sfmt 4700
16343
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 fuelefficient 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.

Note: We may list the same citation of the CFR multiple times because we are proposing numerous changes to the same paragraph. These changes may include
clarifications, deletions, or insertions of text. The term ‘‘current industry standards’’ means equipment manufacturers have been constructing equipment to the more
recent editions of standards.
The Coast Guard 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
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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 × 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
PO 00000
Frm 00037
Fmt 4701
Sfmt 4700
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’’
13 Visit https://www.bls.gov/oes/2021/may/

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.
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 ×
$69.60 × 40 hours per request). See table
6 for industry inputs.

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
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/

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 × 32
hours for each request × $112.45), or
$3,598 for each request. See table 7 for

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 × 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 × 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.

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 × 40
hours for each equivalency × $69.60 =
$27,840) minus (2 equivalency requests
× 40 hours for each equivalency request
× $69.60 = $5,568)]. We estimate 5-year
cost savings of this rule to industry to
be approximately $91,320, using a 7-
16347

annualized cost savings to be
approximately $22,272, using a 7percent discount rate, as shown in table

Federal Government Cost Savings
With this final rule, we expect the
Coast Guard will review annually 2
equivalency requests (10 equivalency
requests × 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 × 32 hours for each
equivalency request × $112.45 =
$7,197)]. We estimate the 5-year
discounted cost savings of this rule to
the Federal Government to be

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
VerDate Sep<11>2014
19:50 Mar 15, 2023
Jkt 259001
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 7percent discount rate. We estimate the
annualized cost savings would be
approximately $22,272, using a 7percent 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

ddrumheller on DSK120RN23PROD with RULES2
Federal Register / Vol. 88, No. 51 / Thursday, March 16, 2023 / Rules and Regulations
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.
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.
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.
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-forprofit 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 companyspecific 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
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.
18 The Coast Guard was unable to find revenue
information for two of these small entities.

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.

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.
ddrumheller on DSK120RN23PROD with RULES2
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

(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 shortcircuit 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

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]]
page 16 of Navigation and Vessel Inspection Circular (NVIC) 2-89,
``Guide for Electrical Installations on Merchant Vessels and Mobile
Offshore Units,'' dated August 14, 1989.\2\
---------------------------------------------------------------------------
\2\ 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.
---------------------------------------------------------------------------
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).

API Recommended Practice (RP) 14F--Recommended Practice
for Design, Installation, and Maintenance of Electrical Systems for
Fixed and Floating Offshore Petroleum Facilities for Unclassified and
Class I, Division 1 and Division 2 Locations, Sixth Edition, October
2018. This document recommends minimum requirements and guidelines for
the design, installation, and maintenance of electrical systems on
fixed and floating petroleum facilities located offshore. By means of
this rule, we reference clause 6.8 of the document in Sec. 111.105-17.
This clause provides guidance on use of conduit, cable seals, and
sealing methods. The incorporation of this standard adds another wiring
option in hazardous locations.
API RP 14FZ--Recommended Practice for Design,
Installation, and Maintenance of Electrical Systems for Fixed and
Floating Offshore Petroleum Facilities for Unclassified and Class I,
Zone 0, Zone 1, and Zone 2 Locations, Second Edition, May 2013. This
document recommends minimum requirements and guidelines for the design,
installation, and maintenance of electrical systems on fixed and
floating petroleum facilities located offshore. By means of this rule,
we reference clause 6.8 of the document in Sec. 111.105-17. This
clause provides guidance on use of conduit, cable seals, and sealing
methods. The incorporation of this standard adds another wiring option
in hazardous locations.
API RP 500--Recommended Practice for Classification of
Locations for Electrical Installations at Petroleum Facilities
Classified as Class I, Division 1 and Division 2, Third Edition,
December 2012 with errata January 2014. This recommended practice
provides guidelines for classifying locations at petroleum facilities
as Class I, Division 1 and Class I, Division 2 locations for the
selection and installation of electrical equipment. We currently
reference the second edition (1997) of this standard in Sec. Sec.
111.106-7(a) and 111.106-13(b). By means of this rule, we reference
instead the more recent, third edition (2012) in those sections. The
2012 edition contains editorial changes, but the technical content has
not changed.
API RP 505--Recommended Practice for Classification of
Locations for Electrical Installations at Petroleum Facilities
Classified as Class I, Zone 0, Zone 1, and Zone 2, Second Edition,
August 2018. The purpose of this recommended practice is to provide
guidelines for classifying locations Class I, Zone 0, Zone 1, and Zone
2 at petroleum facilities for the selection and installation of
electrical equipment. We currently reference the first edition, which
was published in 1997 and reaffirmed in 2013, in Sec. 111.106-7(a) and
111.106-13(b). By means of this rule, we reference instead the more
recent, second edition (2018) in those sections. This does not
substantively change the requirements of those sections.
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.
ASTM F2876-10--Standard Practice for Thermal Rating and
Installation of Internal Combustion Engine Packages for use in
Hazardous Locations in Marine Applications, Reapproved 2015. This
practice covers the method of testing, rating, and installing internal
combustion engine packages for use in hazardous areas in marine
applications. We currently reference the 2010 edition of this standard
in Sec. Sec. 111.106-3(h) and 111.108-3(g). By means of this rule, we
also reference the 2010 edition in new Sec. 111.105-28 regarding
internal combustion engines. This ensures a consistent standard for
these installations on all vessel and facility types.
CSA C22.2 No. 30-M1986--Explosion-proof enclosures for use
in class I hazardous locations, Reaffirmed 2016. This standard covers
the details of construction and tests for explosion-proof enclosures
for electrical equipment to be used in Class I, Division 1, Groups A,
B, C, and D hazardous locations and in gaseous mines. We currently
reference the 1986 edition of this standard in Sec. Sec. 111.106-3(b)
and 111.108-3(b) and by means of this rule incorporate instead the
reaffirmed version therein. The two versions are not substantively
different. We also reference this reaffirmed standard in Sec. 111.105-
3(b), regarding approved equipment, as an additional compliance option.
This affords the broadest and most current selection of IBR explosion
protection standards for all vessel and facility types.
CSA C22.2 No. 213-16--Nonincendive Electrical Equipment
for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2
Hazardous (Classified) Locations, May 2016. This standard provides the
details of construction and testing of electrical
[[Page 16323]]
equipment for use in Class I and II, Division 2 and Class III, Division
1 and 2 hazardous locations. We currently reference the 1987 edition in
Sec. Sec. 111.106-3(b) and 111.108-3(b). By means of this rule, we
reference instead the 2016 edition in these sections and also in Sec.
111.105-3(b) concerning approved equipment. This standard received a
major revision since the 1987 edition based on advances in technology
and changes to related standards. It is an accepted national standard
and one of several available standards for nonincendive electrical
equipment. Our incorporation of this updated edition ensures use of
latest industry practices and including it in Sec. 111.105-3 ensures
that standards are consistent for electrical installations on all
vessel and facility types.
CSA-C22.2 No. 0-10--General requirements--Canadian
Electrical Code, Part II, including Update No. 2, dated November 2014,
Reaffirmed 2015. This standard covers definitions, construction
requirements, marking, and tests of a general nature that applies to
all or several of the individual standards of the Canadian Electrical
Code. We currently reference the ninth edition of this standard in
Sec. Sec. 111.106-3(b) and 111.108-3(b). By means of this rule, we
reference instead the tenth edition, reaffirmed in 2015, in these
sections and in Sec. 111.105-3(b) concerning approved equipment. The
tenth edition includes new requirements for equipment containing lasers
or lithium batteries, criteria for the use of adhesives in the
construction of electrical equipment, surface temperature limits,
attachment plug loading, and the maximum temperature of equipment in
contact with gypsum. Additionally, it incorporates a comprehensive list
of definitions for use in standards for electrical products and
outlines the relationship between this standard and electrical product
standards. We incorporate this more recent edition in subpart 111.105
to ensure that standards are consistent for electrical installations on
all vessel and facility types.
CAN/CSA-C22.2 No. 157-92--Intrinsically safe and
nonincendive equipment for use in hazardous locations, including Update
No. 2, dated June 2003, reaffirmed 2016. This standard specifies the
testing of nonincendive electrical equipment and the details of
construction and tests for intrinsically safe electrical equipment for
use in hazardous locations. We currently reference the 1992 edition of
this standard, which is not substantively different from the reaffirmed
edition, in Sec. Sec. 111.106-3(b) and 111.108-3(b). By means of this
rule, we reference instead the reaffirmed 1992 edition in those
sections. In addition, we are adding a reference to the reaffirmed

IEC 61363-1:1998--Electrical installations of ships and
mobile and fixed offshore units--Part 1: Procedures for calculating
short-circuit currents in three-phase a.c., first edition, 1998-02.
This 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

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.
IEC/TR 60092-370:2009--Technical Report--Electrical
installations in ships--Part 370: Guidance on the selection of cables

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
Sec. 110-10-1(b). Chapter 6 of this resolution is referenced in Sec.
111.108-3(b). The resolution provides requirements for machinery and
electrical installations in hazardous areas of mobile offshore drilling
units.
ISA RP 12.6--Wiring Practices for Hazardous (Classified)
Locations Instrumentation Part I: Intrinsic Safety, 1995. By means of
this rule, we delete this standard from reference in Sec. 111.105-11.
It has been withdrawn by ISA and has been superseded by ANSI/ISA RP
12.06.01 (2003), which we incorporate by reference in Sec. 111.105-11.
ISO 25861:2007(E)--Ships and marine technology--
Navigation--Daylight signalling lamps, first edition, Dec, 1, 2007. By

regarding daylight signaling lamps. This standard provides performance
requirements for daylight signaling lamps pursuant to chapter V of
SOLAS, 1974, as amended, and chapter 8 of the International Code for
Safety for High-Speed Craft. The performance standards for daylight
signaling lamps currently in Sec. 111.75-18 are based on the
international requirements in place in 1996, but the requirements
contained in ISO 25861:2007 superseded those requirements. The ``(E)''
stands for the English version of the standard.
Lloyd's Register Type Approval System-Test Specification
Number 1, March 2019. Lloyd's Register is a vessel classification
society that develops and publishes a comprehensive set of rules for
the construction and maintenance of ships and offshore facilities. The
rules are, in general, developed by IACS and by Lloyd's Register staff,
and passed upon by committees made up of naval architects, marine
engineers, shipbuilders, engine builders, steel makers and other
technical, operating, and scientific personnel associated with the
worldwide maritime industry. Because of classification society rules'
comprehensive nature and long history of ensuring vessel safety and
seaworthiness, they are a valuable supplement to the numerous voluntary
consensus standards incorporated by reference. This specification
details performance and environmental testing required for products
used in marine applications. We currently reference the 2002 edition of
this standard in Sec. 113.05-7(a). By means of this rule, we reference
the more recent 2019 edition. It has been updated several times to keep
pace with changes in environmental testing.

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.

standard provides requirements for nonmetallic outlet boxes, conduit
bodies, flush-device boxes, extension rings, and covers. We currently
reference the second edition (1988) of this standard in Sec. 111.81-
1(d). By means of this rule, we will reference the more recent fourth
edition (2014). UL 514C has been updated to align with advancements in
nonmetallic outlet boxes and requirements in similar standards. To
ensure we address the latest technologies and industry practices, we
incorporate the more recent edition of this standard.
UL 674--Standard for Safety: Electric Motors and
Generators for Use in Hazardous (Classified) Locations, 2011. This
standard provides requirements for electric motors and generators or
submersible and non-submersible sewage pumps and systems suitable for
use in hazardous (classified) locations. We currently reference the
fourth edition (2003) of this standard in Sec. 111.106-3(b) and the
fifth edition (2011) in Sec. 111.108-3(b). By means of this rule, we
reference the more recent fifth edition (2011) in Sec. 111.106-3(b),
and add a reference to this edition in Sec. 111.105-3(b). This ensures
consistent, up-to-date standards for electrical installations on all
vessel and facility types.
UL 823--Electric Heaters for Use in Hazardous (Classified)
Locations, revised November 15, 2007. This standard provides
requirements for electric heaters suitable for use in hazardous
(classified) locations. We currently reference the ninth edition (2007)
of this standard in Sec. Sec. 111.106-3(b) and 111.108-3(b). By means
of this rule, we reference the ninth edition (2007) in Sec. 111.105-
3(b) as well. This ensures that standards are consistent for electrical
installations on all vessel and facility types.
UL 844--Standard for Safety: Luminaires for Use in
Hazardous (Classified) Locations, 2012. This standard provides
requirements for fixed and portable luminaires for installation and use
in hazardous (classified) locations. We currently reference the twelfth
edition (2006) of this standard in Sec. 111.106-3(b) and the
thirteenth edition (2012) in Sec. 111.108-3(b). By means of this rule,
we reference the more recent thirteenth edition (2012) in Sec.
111.106-3(b), and add a reference to this edition in Sec. 111.105-
3(b). This latest edition includes the following minor technical
revisions:
[cir] Revisions for test paint for spray booth luminaires;
[cir] Revisions for temperature tests at elevated ambient
temperatures; and
[cir] Clarification of required number of as-received samples of
polymeric enclosure materials.
UL 913--Standard for Safety: Intrinsically Safe Apparatus
and Associated Apparatus for Use in Class I, II, and III, Division 1,
Hazardous (Classified) Locations, Eighth Edition, 2013. This standard
provides requirements for apparatus or parts of apparatus intended for
installation in hazardous locations. We currently reference the sixth
edition (2002) of this standard in Sec. 111.105-7(a) and the seventh
edition (2006) in Sec. Sec. 111.106-3(b) and 111.108-3(b). By means of
this rule, we remove references to these earlier editions and reference
the more recent eighth edition (2013) in Sec. Sec. 111.105-3(b),
111.106-3(b), and 111.108-3(b). This latest edition includes the
following technical revisions:
[cir] Revisions to reference the latest 2013 editions of UL 60079-0
and UL 60079-11;
[cir] Deletion of redundant references to applicable ordinary
locations requirements;
[cir] Revisions to address the equivalent installation and use of
Class I, Division 1 and Class II intrinsically safe and associated
apparatus in Zone 20 hazardous (classified) locations respectively; and
[cir] Revisions to dust-tight enclosures for Class II Intrinsically
Safe Apparatus.
UL 1042--Standard for Safety Electric Baseboard Heating
Equipment, revised September 9, 2014. This standard provides
requirements for portable and fixed electric baseboard heating
equipment rated at 600 V or less. We currently reference the third
edition (1994) of this standard in Sec. 111.87-3. By means of this
rule, we reference the more recent fifth edition (2014). This latest
edition includes the following technical revisions:
[cir] Revisions requiring portable heater power supply cords to
meet UL 817;
[cir] Revisions requiring electric connections to meet established
UL standards, UL 310, UL 486A-486B, UL 886C, UL 486E, or UL 1977;
[cir] Revisions to equipment grounding provisions; and
[cir] Update to the leakage current test.
UL 1072--Standard for Safety Medium-Voltage Power Cables,
revised June 19, 2013. This standard provides requirements for shielded
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
and dust-ignition-proof electrical equipment for installation and use
in hazardous locations. We currently reference the third edition (2000)
of this standard in Sec. 111.105-9 and the fourth edition (2006) in
Sec. Sec. 111.106-3(b) and 111.108-3(b). 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.

requirements of
this subchapter.
------------------------------------------------------------------------
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.
Table 3--Summary of Impacts of the Final Rule
------------------------------------------------------------------------
Category Summary
------------------------------------------------------------------------
Applicability..................... Incorporate by reference electrical
engineering standards or update
existing standards through
incorporation by reference in
subchapter J of Title 46 CFR.
Affected Population............... Cost savings based on an 80
percent reduction of equivalency
requests from owners and operators
of 183 new U.S.-flagged vessels
that entered service over the past
5 years.
Standards used by
approximately 5,602 U.S.-flagged
vessels (affected population varies
by CFR part and subpart, see table
4).
Benefits.......................... Industry Cost Savings ($2021, 7-
percent discount rate):
5-year period of analysis: $91,320.
Annualized: $22,272.
Government Cost Savings ($2021, 7-
percent discount rate):
5-year period of analysis: $118,032.
Annualized: $28,787.
Total Cost Savings ($2021, 7-percent
discount rate):
5-year period of analysis: $209,352.
Annualized: $51,059.
Unquantified benefits include
providing flexibility by offering
options or alternatives for IBR and
non-IBR provisions, removing
regulatory redundancy and confusion
by updating standards and
simplifying regulatory text through
editorial changes, and
consolidating regulatory text.
------------------------------------------------------------------------
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

U.S.-flagged vessels entering service annually will generate cost
savings by submitting fewer equivalency requests to the Coast

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.

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

find 2021 unloaded mean hourly wage rate for occupations in the
United States.
\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.

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\ https://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:
ANSI/ISA-RP12.06.01-2003--Recommended Practice for Wiring
Methods for Hazardous (Classified) Locations Instrumentation Part 1:
Intrinsic Safety, approved 16 April 2003 (``ANSI RP12.06.01''),
