II. Background, Basis, and Purpose

    This rule incorporates by reference updated marine engineering 
standards in Title 46 of the Code of Federal Regulations (CFR) 
subchapter F, including standards for boilers, pressure vessels, 
auxiliary machinery, piping, valves, and fittings, for various types of 
vessels. The rule also adds a limited number of alternative standards 
and eliminates outdated or unnecessarily prescriptive regulations.
    The Office of Management and Budget (OMB) directs, via OMB Circular 
A-119, that federal agencies use industry-based voluntary consensus 
standards in lieu of government-unique requirements, where appropriate. 
The Coast Guard actively participates in the development of industry 
standards for safety of marine equipment at the International Maritime 
Organization (IMO), the International Organization for Standardization 
(ISO), ASTM International (ASTM), American Society of Mechanical 
Engineers (ASME), and other standards-setting bodies that belong to the 
American National Standards Institute (ANSI). Recently published 
editions of these standards provide necessary updates to materials, 
testing practices, and technologies, enhancing safety and compliance.
    The Coast Guard has statutory authority to issue regulations under 
Title 43, United States Code (U.S.C.), section 1333(d), 46 U.S.C. 3306 
and 3703, and the Department of Homeland Security (DHS) Delegation No. 
00170.1, Revision No. 01.3, paragraph (II)(92)(b), which delegates 
authority under these statutes to the Commandant of the Coast Guard. 
Title 43 of the U.S.C., section 1333(d) grants the Secretary 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. Title 46 of the U.S.C., section 
3306(a)(1), authorizes the Secretary to prescribe regulations for the 
design, construction, alteration, repair, and operation of vessels 
subject to inspection, including equipment, appliances, propulsion 
machinery, auxiliary machinery, boilers, unfired pressure vessels, 
piping, and electric installations. Additionally, 46 U.S.C. 3703(a) 
grants the Secretary authority to regulate tank vessels regarding the 
construction, alteration, repair, maintenance, operation, and equipping 
of vessels that may be necessary for increased protection against 
hazards to life and property, for navigation and vessel safety, and for

[[Page 50059]]

enhanced protection of the marine environment.
    On October 19, 2021, the Coast Guard published a notice of proposed 
rulemaking (NPRM) titled ``Updates to Marine Engineering Standards,'' 
(86 FR 57896) 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 is available in that NPRM.

III. Discussion of Comments

    During the 60-day comment period for the NPRM, beginning on October 
19, 2021, the Coast Guard received a comment requesting an extension of 
the comment period. The Coast Guard granted this request, and, on 
December 20, 2021, published an extension of the comment period (86 FR 
71864), for 45 days, until February 3, 2022. During the extended 
comment period, we received two comments. 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 in the following 
sections, starting with general comments then moving to specific 
comments.

A. General Comments on the Proposed Rule

    We received two comments supporting \1\ the update of many of the 
standards proposed for incorporation by reference (IBR) in subchapter 
F, emphasizing the importance of ``referencing the latest editions of 
widely used consensus standards.'' Both comments also supported the 
addition of alternative standards and the elimination of outdated or 
unnecessarily prescriptive regulations. We thank the commenters for 
their support of this update to subchapter F.
---------------------------------------------------------------------------

    \1\ One commenter provided a lengthy statement detailing its 
full support of the proposed updates, while the other commenter 
endorsed the first commenter's statement. When we use ``both 
comments'' we mean either both comments explicitly, or the first 
comment as supported by the second.
---------------------------------------------------------------------------

B. Editorial Comments on the Proposed Rule

    Comment: Two commenters recommended that, for the sake of clarity, 
proposed 46 CFR 56.60-1(a)(2) be turned into a multiple-paragraph list. 
The same commenters stated that the reference to table 56.60-1(b) in 
Sec.  56.60-1(b) appears erroneous and should probably refer to table 2 
to Sec.  56.60-1.
    Response: We agree and have reorganized Sec.  56.60-1(a)(2) so that 
it now constitutes new Sec.  56.60-1(a)(2) through (4). We have revised 
the table reference in Sec.  56.60-1(b) to conform with other updates 
to table numbering as proposed in the NPRM.

C. Substantive Comments on Standards Within the Proposed Rule

    Comment: Two commenters recommended that the Coast Guard continue 
the IBR of ASME B16.10, Face-to-Face and End-to-End Dimensions of 
Valves, which we proposed to remove in the NPRM.
    Response: Because ASME B16.10 is already referenced in ASTM F1155, 
which we proposed for IBR in the NPRM, in practice ASME B16.10 will 
continue to be incorporated by reference even if it is not specifically 
mentioned. Specifically incorporating ASME B16.10 is redundant when the 
standard and its requirements are provided within ASTM F1155.
    Comment: Two commenters recommended the following standards be 
incorporated by reference in Part 56:
    <bullet> American Petroleum Institute (API) standard API Spec 6D, 
Specification for Pipeline and Piping Valves, 25th Edition;
    <bullet> ASTM B148-18, Standard Specification for Aluminum-Bronze 
Sand Castings; and
    <bullet> ASTM D2996-17, Standard Specification for Filament-Wound 
``Fiberglass'' (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe.
    Response: Because ASTM D2996 is already referenced within ASTM 
F1155, which we incorporate by reference by means of this final rule, 
it is not necessary to duplicate the reference. With regards to ASTM 
B148 and API Spec 6D, these standards are neither currently referenced 
within subchapter F, nor were they proposed for IBR in the NPRM. We 
recognize that there are numerous national and international standards 
that provide similar requirements and equivalent performance for the 
same equipment or system. Naval architects and system designers may 
submit for approval components designed to alternative standards that 
provide an equivalent level of safety in accordance with the provisions 
of 46 CFR 50.20-30.
    Comment: We received two comments recommending against 
incorporating by reference API Recommended Practice 14C, Analysis, 
Design, Installation, and Testing of Safety Systems for Offshore 
Production Facilities, Eighth Edition, February 2017 (which would 
update the current incorporation by reference within subchapter F of an 
earlier edition of this standard), and API STD 53, Well Control 
Equipment Systems for Drilling Wells, 5th Edition (which would replace 
a superseded standard currently incorporated by reference within 
subchapter F). The commenters expressed concern that, since the June 4, 
2013, Memorandum of Agreement between the Coast Guard and the Bureau of 
Safety and Environmental Enforcement (BSEE) designates BSEE as the lead 
agency for safety and operations on outer continental shelf (OCS) 
facilities, and the referenced standards are already included in BSEE 
regulations, including them in subchapter F as well could create a risk 
of edition conflict between BSEE and the Coast Guard. For the same 
reason, the commenter recommended removing the entirety of subpart 
58.60--Industrial Systems and Components on Mobile Offshore Drilling 
Units (MODUs), and using the standards incorporated by reference in 30 
CFR 250.198 for industrial systems and components as well as marine 
systems and components for all oil and gas facilities on the OCS.
    Response: We have elected to retain these standards in subchapter F 
and not remove subpart 58.60 from the CFR, in order to maintain clarity 
regarding requirements for engineering systems. The ship and facility 
marine engineering and electrical systems that the Coast Guard 
regulates interface with industrial systems under the jurisdiction of 
BSEE. The Coast Guard and BSEE have a shared mission of ensuring safety 
on the OCS. We work together closely to ensure our requirements are not 
in conflict.
    Comment: We received a comment regarding the IBR of the American 
Bureau of Shipping (ABS) standard, ABS Rules for Building and Classing 
Marine Vessels, 2020, Part 4, Vessel Systems and Machinery, which we 
proposed in the NPRM as an update of the earlier 2003 standard already 
incorporated in subchapter F. The commenter argued that ``incorporating 
the classification rules of [ABS] in subchapter F (and 46 CFR Chapter 
I) uses the rules of one classification society to set a regulatory 
baseline, which could competitively disadvantage other societies and 
deprive the industry of knowledge and innovation available in other 
societies' rules.''
    Response: We appreciate the comment, but do not agree. Many vessels 
normally subject to the regulations of subchapter F are enrolled in the 
Alternate Compliance Program (ACP), where the rules of any recognized 
classification society may be used in lieu of the requirements of 
subchapter F. Given that the rules of other recognized classification 
societies are already in wide use through the ACP

[[Page 50060]]

and will remain so, the IBR of the ABS standards will not disadvantage 
other classification societies or interfere with the sharing of 
expertise throughout the industry. We discussed this in depth in 
``Discussion of Proposed Rule'' in the NPRM.\2\

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

D. Comments Recommending Additional Regulatory Action

    Comment: Two commenters recommended updating 33 CFR subchapter N to 
clarify the applicability of the rule to existing and new floating OCS 
facilities, nearly all of which are not, properly speaking, ``vessels'' 
or ``ships.'' The commenters also recommended that the Coast Guard act 
on the March 28, 2018, National Offshore Safety Advisory Committee 
(NOSAC) Production Subcommittee Final Report on [U.S. Coast Guard] 
Regulatory Reform recommendation that ``The Coast Guard should issue 
NOSAC a new Task Statement to evaluate the suitability of the 
regulations in 46 CFR Subchapter F (Marine Engineering) and 46 CFR 
Subchapter J (Electrical Engineering) to floating OCS facilities.'' \3\ 
The commenters suggested that, since floating OCS facilities are not, 
properly speaking, ``vessels'' or ``ships,'' the application of 
subchapter F to such facilities has led to multiple requests for 
equivalencies and alternatives, and that while the Coast Guard has 
attempted to address this via policy letter,\4\ this policy letter only 
applies to floating OCS facilities classed with a classification 
society.

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

    The commenters suggested that, at a minimum, the Coast Guard should 
update 33 CFR 143.120 to establish the date on which this rule would 
apply to a new floating OCS facility.
    Response: An update to 33 CFR subchapter N regarding its 
applicability to floating OCS facilities and a statement on the same 
issue to NOSAC are outside the scope of this rulemaking but could be 
addressed in a future rulemaking. We encourage questions regarding the 
applicable regulations for floating OCS facilities to be sent either to 
the Coast Guard's Eighth District Outer Continental Shelf Division 
Staff (website: <a href="https://www.atlanticarea.uscg.mil/D8/OCS">https://www.atlanticarea.uscg.mil/D8/OCS</a>) or the Outer 
Continental Shelf National Center of Expertise (OCSNCOE) (website: 
<a href="https://www.dco.uscg.mil/OCSNCOE">https://www.dco.uscg.mil/OCSNCOE</a>). As to an update to 33 CFR 143.120, 
the date that 33 CFR subchapter N requires compliance with subchapter F 
is the effective date, 90 days after the publication of this final 
rule.

E. Comments Recommending Additional Non-Regulatory Action

    Comment: Two commenters supported the proposed IBR of ASTM F1155-10 
(Reapproved 2015), Standard Practice for Selection and Application of 
Piping System Materials, but also recommended the Coast Guard's Marine 
Safety Center (MSC) cancel Marine Safety Center Technical Note (MTN) 
02-10, Material Selection for Vital Piping Systems, as superseded by 
the adoption of this standard.
    Response: We generally agree, but we note that ASTM F1155 has 
application to all shipboard piping systems, while MTN 02-10 is focused 
on ``vital'' shipboard systems. MTN 02-10 will be reviewed and revised 
if necessary.

F. Comments on the Regulatory Analysis (RA)

    Comment: Two comments expressed concern that table 3 of the RA did 
not specifically address floating OCS facilities and did not provide 
enough clarity to determine if floating OCS facilities were included 
within the table. The commenters recommended that the Coast Guard 
undertake changes to the Marine Information for Safety and Law 
Enforcement (MISLE) system and its internal documentation to eliminate 
any confusion regarding the inclusion or exclusion of floating OCS 
facilities, not only for the purpose of this rule but also for future 
Coast Guard regulatory actions.
    Response: We agree with these comments. In our MISLE database, 
floating production systems are listed as being inspected under 46 CFR 
subchapter I-A; this is incorrect, and, as a result, we overstated the 
number of MODUs in the RA, which lowered the population of vessels in 
the ``Industrial Vessel'' category. After further analysis we revised 
the population of MODUs to one, because we incorrectly classified the 
remainder based on the subchapter inspection field in MISLE. The Coast 
Guard will amend its MISLE database to correctly label these vessels.
    While we did update table 4 of the RA in response to public 
comments, we did not receive feedback from the public that would impact 
our estimate of the number of equivalency requests that are submitted 
to the Coast Guard on an annual basis. Therefore, the regulatory 
assessment of costs, cost savings, and benefits of the NPRM remain 
unchanged, other than the use of more current economic data, where 
available.
    Comment: We also received two related comments regarding the number 
of specific vessel types, suggesting that the listing of 110 MODUs in 
table 3 of the RA was not accurate and that there are fewer than 5 
U.S.-flagged MODUs in active service.
    Response: We agree with these comments. As stated above, in the RA 
for the proposed rule, we incorrectly labeled ``floating production 
systems'' and counted them as MODUs. This overstated the number of 
MODUs because these systems are incorrectly listed in MISLE as being 
inspected under title 46 CFR subchapter I-A. After further analysis, we 
revised the population of MODUs for the final rule to one, because we 
incorrectly classified the rest based on the subchapter inspection 
field in MISLE. Floating production systems are facilities certificated 
and inspected under 33 CFR subchapter N and not vessels inspected under 
46 CFR subchapter I. We overestimated the number of affected vessels in 
the proposed rule; therefore, in this final rule we revise the number 
of vessels in the subchapter I from 6,086 down to 623. Because we 
updated the entire population for this final rule, the total number of 
vessels and facilities is revised down from 16,148 in the proposed rule 
to 5,655 (see table 4 in this document).

IV. Discussion of Rule

A. General Discussion

    In order to decrease the likelihood of introducing errors, to 
improve efficiency during the publication process, and to meet drafting 
and formatting requirements for publication, we are revising or 
revising and republishing entire sections, subparts, and parts, as 
appropriate. Except as explained as a change in this preamble, the 
individual (piecemeal) changes are detailed in the proposed rule, 
published on October 19, 2021 (86 FR 57896).
    In general, the rule makes the following changes:
    1. Corrections--we amend several sections to correct inadvertent 
errors or deletions. We also remove material that is obsolete or 
superfluous, and update contact information for Coast Guard offices and 
standards organizations.
    2. Stylistic Revisions--we revise the language of some sections, 
primarily for greater clarity. This includes revising sentences 
containing the word ``shall'' to use ``must'' or another grammatically 
equivalent word or phrase in accordance with plain language guidelines. 
We also standardize terms

[[Page 50061]]

that were variously presented as compound words, hyphenated 
constructions, or multi-word phrases using the format preferred by the 
Government Publishing Office.
    3. Updated cross references--we update cross references to reflect 
the relocation within the CFR of pertinent provisions. We also 
standardize designations for tables, figures, notes, and formulas using 
the format preferred by the Office of the Federal Register (OFR).
    4. Updated industry standards--we update cross-references to 
industry standards by adding new references, replacing references to 
superseded standards or editions, and by conforming text accordingly. 
We incorporate these updated standards because they reflect the latest 
available technologies, practices, and procedures that are recommended 
by consensus bodies, ship classification societies, and other maritime 
organizations with experience in the industry. As the baseline upon 
which other standards, rules, and equivalency requests are evaluated, 
it is important that subchapter F incorporate up-to-date references. 
The class rules of ABS, in particular, are incorporated by reference in 
multiple locations within subchapter F and 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 has also authorized classification societies in 
accordance with 46 CFR part 8. These authorized classification 
societies are listed on the Coast Guard website \5\ and have been 
delegated the authority to perform certain functions and certifications 
using their respective class rules for vessels enrolled in the ACP. For 
vessels not enrolled in the ACP, the class rules of an authorized 
classification society may be proposed as an alternative to the ABS 
class rules incorporated by reference for engineering systems and 
equipment. Table 1 indicates the sections we amend, and why.

B. Standards Incorporated by Reference To Be Updated or Added

    Following this paragraph, we include an alphabetical list of the 
standards we are updating or adding, each with a listing of the 
sections in which they appear in 46 CFR. For each standard listed, we 
describe the topics covered by the standard, the changes to the 
standard, any difference between the older edition of standards 
currently included within the CFR via IBR and the edition adopted, and 
a list of subparts or sections that reference the standard.
    <bullet> ABS Rules for Building and Classing Marine Vessels, Part 
4, Vessel Systems and Machinery, January 2020. This standard updates 
the 2003 standard, incorporated by reference in Sec. Sec.  58.01-5, 
58.05-1, 58.10-15, 58.20-5, 58.25-5, 62.25-30, 62.35-5, 62.35-35, 
62.35-40, 62.35-50, and 62.50-30. In 2020, ABS changed the name of the 
Steel Vessel Rules to Marine Vessel Rules. All parts and sections 
contain the same information along with updates to reflect the current 
technologies for commercial vessels. The rules contain a comprehensive 
set of construction and maintenance requirements for ships and offshore 
facilities.
    <bullet> ABYC P-1-14, Installation of Exhaust Systems for 
Propulsion and Auxiliary Engines, reaffirmed 2014. This American Boat 
and Yacht Council (ABYC) standard updates the 1973 standard, 
incorporated by reference at Sec.  58.10-5. It contains the rules and 
guidance for the safe installation and operation of exhaust systems for 
propulsion and auxiliary engines. Updates to the standard are editorial 
(non-substantive) in nature.
    <bullet> ANSI Z21.22-2015, Relief valves for hot water supply 
systems, July 2015. This standard updates the 1986 edition incorporated 
by reference at Sec.  63.25-3. This standard establishes requirements 
for relief valves for hot water systems. It has been regularly revised 
to accommodate technological developments, to address administrative 
requirements, to incorporate interpretations, and to clarify the 
standard intent. It is the internationally accepted standard.
    <bullet> API RP 14C, Analysis, Design, Installation, and Testing of 
Safety Systems for Offshore Production Facilities, Eighth Edition, 
February 2017 with errata 1 May 2018. This standard updates the 1986 
edition incorporated by reference in Sec.  58.60-9. This document 
presents provisions for designing, installing, and testing both process 
safety and non-marine emergency support systems on an offshore 
production facility. The updates made to the standard are editorial in 
nature.
    <bullet> API STD 53, Well Control Equipment Systems for Drilling 
Wells, Fifth Edition, December 2018. This standard replaces API 
Recommended Practice 53 (API RP 53), the second edition of which is 
currently incorporated by reference at Sec.  58.60-7. API STD 53 
promotes best safety practices for the oil and gas industry during 
drilling operations, principally focusing on blowout prevention.

for the ASME Boiler Pressure Vessel Code. Making stylistic changes 
throughout part 53 for greater clarity and readability.
    Section 53.01-1 Incorporation by reference.
    Modifying paragraph (b) to update contact information for the ASME, 
and modifying paragraph (c) to reflect Underwriters Laboratories change 
of name to UL Solutions and update the organization's contact 
information.
    Section 53.01-10 Service restrictions and exceptions (replaces HG-

    Modifying paragraph (b) to identify when shop inspection is 
required. Part 54 refers to shop inspection of pressure vessels under 
construction in several locations, but the term is not used here.
    Adding new paragraph (c), redesignating existing paragraph (c) as 
new paragraph (d), and removing the requirement for stamping with the 
Coast Guard Symbol. The requirement for the use of the Coast Guard 
Symbol on pressure vessels is often misunderstood. By applying the 
symbol, the marine inspector is documenting that the pressure vessel 
meets Coast Guard requirements for pressure vessels on ships. Adding a 
paragraph clarifies which pressure vessels do not require stamping.
    Section 54.10-20 Marking and stamping.
    Modifying paragraph (a)(2) to clarify numbering requirements. The 
requirement for Coast Guard numbering of pressure vessels is often 
misunderstood. Numbering is only required when the Coast Guard has 
inspected the pressure vessel during construction (shop inspection).

Marine Vessel Rules (2020) are referenced instead because this section 
of the ABS Rules is more directly applicable to generators.
    Deleting the requirements for generators to comply with Sec. Sec.  
111.12-1 (b) and (c), and parenthetical items 6 and 7 in Table 62.35-
50.

readability.
    Section 63.01-3 Scope and Applicability.
    Amending paragraph (b) to remove language regarding electric 
cooking equipment, electric air heaters, and electric oil immersion 
heaters. The requirements for these electric appliances are covered in 
46 CFR subchapter J part 111.
    Section 63.05-1 Incorporation by reference.
    Modifying paragraphs (a) through (f) to update contact information 
for the ANSI, ASME, ASTM, IMO, ISO, and UL Solutions, respectively.

design standard for incinerators.
Part 64--Marine Portable Tanks and Cargo Handling Systems
    Replacing the words ``ASME Code'' with ``ASME BPVC'' throughout 
part 64, as BPVC is recognized as the appropriate acronym for the ASME 
Boiler Pressure Vessel Code. Making stylistic changes throughout part 
64 for greater clarity and readability.
    Section 64.2 Incorporation by reference.
    Modifying paragraph (b) to update the address for the ASME.
E. Additional Changes From the NPRM
    In addition to the changes discussed above, we are making further 
editorial changes from the text proposed in the NPRM, as follows.
    In Sec.  56.30-20(d), correcting an erroneous Fahrenheit to Celsius 
conversion. The Fahrenheit temperature currently provided in the CFR is 
correct.
    In Sec.  56.50-60(n), restoring the word ``flammable,'' as it was 
inadvertently deleted.
    In Sec.  56.50-70(e), clarifying that the openings indicated in 
this paragraph are openings for fuel tanks.
    In Sec.  56.50-75(b)(1), adding ``seamless steel'' to the list of 
acceptable materials. Seamless steel has always been acceptable under 
this paragraph as an ``other material,'' but, because it is commonly 
used, we are adding it to the list for clarity.
    In Sec.  56.50-75(b)(6), removing the words ``on vessels less than 
100 gross tons and tank barges'' as unnecessary because this 
applicability condition is already specified in Sec.  56.50-75(b).
    In Sec.  56.50-95(f), removing redundant text relating to 
prohibitions on the use of heat-sensitive materials.
    In Table 2 to Sec.  56.50-105, removing footnote 2 and renumbering 
the remaining footnotes. Footnote 2 redirected readers to part 54 for 
additional information, and all the necessary information is found in 
the table. Deleting cross-references to table 1 to Sec.  56.85-10(c) as 
we are removing that table, as discussed below.
    In Sec.  56.60-1, relocating note 1 to table 1 to Sec.  56.60-1(a) 
to follow the table rather than precede it and redesignating the other 
note as note 2 to table 1 to Sec.  56.60-1(a).
    Reorganizing the information in table 1 to Sec.  56.60-2 and its 
associated footnotes to ensure all substantive requirements are found 
in the table itself and renumbering the remaining footnotes.
    In Sec.  56.85-10, revising the text and removing table 1 to Sec.  
56.85-10(c) to simplify the information presented and focus on the 
incorporated standard, ASME B31.1. The relevant information regarding 
heat treatment of welds is already provided by ASME B31.1 and it is 
unnecessary to supplement the text with additional Coast Guard 
requirements that are redundant to ASME B31.1. In addition, removing a 
cross-reference to table 1 to Sec.  56.85-10(c) in Sec.  56.50-105, as 
noted above.
    As with Sec.  56.85-10, revising the text in Sec.  56.85-15 to 
remove unnecessary supplementary information regarding post-heat 
treatment of welds and, instead, directing readers to follow the 
relevant section and table of the incorporated standard, ASME B31.1.
    In Sec.  56.95-10 (a)(1), correcting an Imperial unit/Metric system 
unit conversion that is incorrect in the current CFR.
    In Sec.  58.05-1(b), removing the requirement for drawings to be 
submitted in quadruplicate because drawings are typically submitted 
under this section electronically, making multiple copies unnecessary.
    In Sec.  58.16-10(e), removing the requirement for plans to be 
submitted in triplicate because plans are typically submitted under 
this section electronically, making multiple copies unnecessary.
    Restoring Sec.  58.25-25(a) and (e), with minor stylistic changes, 
as these paragraphs were inadvertently deleted.
    In Sec.  58.50-1(b), removing the text ``converted on or after July 
1, 1935'' because the emergency systems requirements under this section 
now apply to all ships.
    Reorganizing the information in table 1 to Sec.  62.35-50 and its 
associated footnotes to ensure all substantive requirements are in the 
table itself and renumbering the remaining footnotes.
    In Sec.  62.50-20(g)(2), correcting a drafting error by changing 
the reference to ``Sec. Sec.  111.12-11(g) and 111.30-1 of this 
subchapter'' to read ``Sec. Sec.  111.12-11(g) and 111.30-1 of this 
chapter.'' The referenced sections are in the same chapter as Sec.  
62.50-20(g)(2), but not the same subchapter.
    In Sec.  64.2, removing the incorporation by reference of section 
VIII of the ASME BPVC, 1974 edition, as it is only relevant as the 
source for a constant used in a calculation in Sec.  64.63. The actual 
value of the constant, given in that section, is sufficient for the 
calculation.
    In Sec.  64.63, removing the reference to the 1974 edition of 
section VIII of the ASME BPVC as the source of the value of constant C 
used in calculating total emergency venting capacity. The source of 
constant C is not required for this calculation, and as noted above we 
are removing the incorporation by reference

[[Page 50079]]

of section VIII of the ASME BPVC for this part.

V. Incorporation by Reference

    Material for incorporation by reference appears in 46 CFR parts 50, 
52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and 64 and is summarized in 
section IV.B of this preamble. Copies of the material are available 
either at the publisher's web address listed in the incorporation by 
reference sections in 46 CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 
62, 63, and 64 or by contacting the publisher listed for those 
standards. We reviewed and updated all the publisher's web addresses 
listed in the parts to ensure they are current. 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.
    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.
    The Director of the Federal Register approved the material in 46 
CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, and 63 for 
incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51.

VI. Regulatory Analyses

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

A. Regulatory Planning and Review

    Executive Orders 12866 (Regulatory Planning and Review), as amended 
by Executive Order 14094 (Modernizing Regulatory 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 costs and 
benefits, reducing costs, harmonizing rules, and promoting flexibility.
    As OMB has not designated this rule a significant regulatory action 
under section 3(f) of Executive Order 12866, as amended by Executive 
Order 14094, it has not reviewed this regulatory action. An RA follows.
    The Coast Guard received four public comments on the affected 
population in the RA for the proposed rule. Two of these comments 
stated that the RA in the NPRM did not provide clarity on the inclusion 
of OCS facilities. We also received two comments, with essentially the 
same content, stating that the suggested listing of 110 MODUs in table 
3 of the RA in the NPRM was incorrect. We discuss our responses to 
these comments in section III.F of the preamble of this final rule. We 
are incorporating the commenters' suggestions into the RA for this 
final rule and are revising the population of MODUs and Cargo and 
Miscellaneous Vessels based on MISLE Data.
    We are also revising our affected population estimate from 16,148 
vessels and facilities to 5,655. While preparing this final rule we 
obtained the most current data from the MISLE database, and determined 
we likely overcounted in our analysis in the NPRM (see Affected 
Population section for details).\6\ Additionally, we updated the mean 
hourly wage rate for private sector workers and Coast Guard military 
and civilian personnel using 2022 data. Furthermore, we updated the 
load factor used to account for non-wage benefits for private sector 
employees by using Q4 2022 U.S. Department of Labor's Bureau of Labor 
Statistics (BLS) data instead of Q4 2020 BLS data. We further revised 
the load factor for civilian Coast Guard marine engineers from 1.75 to 
1.69 to be consistent with other recently published rulemakings from 
the Coast Guard's Office of Design and Engineering Standards (CG-ENG). 
We present a summary of changes to the RA from the NPRM to the final 
rule in table 2, below.
---------------------------------------------------------------------------

    \6\ The updated affected population estimate of 5,655 vessels 
and facilities subject to subchapter F is similar to the estimate 
from the Update to Electrical Engineering Regulations (Subchapter J) 
final rule published on March 16, 2023. There is a high degree of 
overlap in the populations of vessels and facilities subject to 
subchapters F and J; therefore, we believe this revised estimate is 
more accurate than what we presented in the NPRM. Readers can access 
the Subchapter J final rule at <a href="http://www.federalregister.gov/documents/2023/03/16/2023-04370/update-to-electrical-engineering-regulations">www.federalregister.gov/documents/2023/03/16/2023-04370/update-to-electrical-engineering-regulations</a>.

    With this final rule, the Coast Guard updates 46 CFR subchapter F. 
This final rule aligns the standards for U.S.-flagged vessels and 
facilities in subchapter F with current industry practices to ensure 
that regulatory requirements are consistent with current industry 
standards. Most of the updates simply incorporate by reference the more 
recent versions of the same standards with little or no substantive 
change. In some cases, the more recent editions reflect more modern 
technologies, terminology, and practices. The updates also correct 
regulatory language and remove redundant and outdated references. The 
Coast Guard finds no additional costs associated with this rule and 
estimates this rule saves the regulated public and the Federal 
Government approximately $9.762 million over the 10-year period of 
analysis, discounted at 7 percent and in 2022 dollars. The total 
annualized cost savings are an estimated $1.390 million, discounted at 
7 percent and in 2022 dollars.
    The following RA provides an evaluation of the economic impacts 
associated with this final rule. Table 3 provides a summary of the 
rule's costs and benefits.

                                     4, 1995).\7\
------------------------------------------------------------------------

    The objective of the final rule is to update design standards in 46 
CFR subchapter F by incorporating by reference more recent industry 
standards. The final rule provides clarity, simplifies regulatory 
compliance for industry with the removal of obsolete regulations, and 
revises current regulatory text, which includes the correction of 
errors.\8\
---------------------------------------------------------------------------

    \7\ The rule continues the Coast Guard's response to the 
Presidential Regulatory Reform Initiative of March 4, 1995, and 
directives including Executive Orders 12866 and 13563 that are 
intended to improve regulation and the regulatory process. The 
provisions of this rule remove outdated regulations, revise current 
regulatory text, and incorporate by reference more recent national 
and international industry standards into the CFR. The Coast Guard 
recognizes the significant technological advances technology and 
equipment which is used or carried on vessels. As a result, this 
rule encourages the use of newer equipment and promotes adherence to 
modern standards in the industry.
    \8\ We present a full list of corrections in table 1 of the 
preamble.
---------------------------------------------------------------------------

Affected Population
    The Coast Guard analyzed the impacts of the final rule to determine 
the affected population and how the rule affects vessel and facility 
owners and manufacturers. The engineering updates for subchapter F 
potentially affect the vessels and facilities inspected under the 
following subchapters: D ``Tank Vessels;'' H ``Passenger Vessels;'' I 
``Cargo and Miscellaneous Vessels;'' I-A ``Mobile Offshore Drilling 
Units;'' L ``Offshore Supply Vessels;'' O ``Certain Bulk Dangerous 
Cargoes;'' O-I ``Combination Bulk Cargo;'' O-D ``Combination Bulk 
Cargo-including chemicals;'' R ``Nautical Schools;'' U ``Oceanographic 
Research Vessels;'' and 41 floating production systems (facilities) in 
33 CFR subchapter N ``Outer Continental Shelf Activities.'' \9\ Because 
the rule impacts only new vessels or those undergoing major 
conversions, we estimate that fewer than 200 vessels will be impacted 
annually.\10\
---------------------------------------------------------------------------

    \9\ We excluded public vessels from the population.
    \10\ Based on input from Coast Guard subject matter experts with 
relevant technical expertise in the Office of Design and Engineering 
Standards (CG-ENG).
---------------------------------------------------------------------------

    We estimate the final rule affects about 5,614 vessels and 41 
facilities owned by approximately 952 owners and operators. The rule 
directly impacts vessel owners or operators procuring a new vessel or 
engaging in a major conversion of an existing vessel under conditions 
specified in the rule. Large self-propelled vessels generally have a 
greater number of complex engineering systems covered in subchapter F 
than smaller vessels or barges. With the updates to engineering 
standards in this final rule, we expect, therefore, that large self-
propelled vessels are more likely to be impacted.
    In the NPRM for this rulemaking, we significantly overcounted the 
number of vessels subject to subchapter F because two categories of 
vessels in MISLE that do not have distinct 46 CFR subchapters, 
``industrial vessels'' and ``tank barges,'' were incorrectly assumed to 
be subject to subchapter F's marine engineering requirements in all 
cases. Subchapter F is generally applicable only to larger vessels such 
as cargo ships, large passenger vessels, and tank vessels, so many 
vessels in the categories mentioned above are not subject to its 
requirements. In addition, because cargo and tank barges are not self-
propelled, and subchapter F primarily focuses on vital engineering 
systems such as propulsion and steering systems, much of subchapter F 
is not applicable to barges.
    In this final rule we revise the population estimate, as shown in 
table 4 below. The total affected population of vessels and facilities 
is reduced from 16,148 in the proposed rule to 5,655 in the final rule. 
However, vessels are generally subject to the regulations in effect at 
the time of ship construction. Therefore, only vessels constructed 
subsequent to the effective date of this final rule will be subject to 
its requirements, so our estimate of the average number of new vessels 
entering service annually (provided in the last row of table 4) 
provides a much more realistic picture of the affected population of 
this final rule than does the total universe of vessels subject to 
subchapter F.

Note: These data are based on Coast Guard data found in the MISLE
  database as of September 9, 2022.

    The rule also affects businesses involved in vessel or facility 
manufacturing. There are approximately 83 shipyards and manufacturers 
of vessels or vessel components in the affected population. However, 
the Coast Guard believes that because equipment and vessel 
manufacturers participate in the development and revision of marine 
industry standards and ship design requirements, manufacturers are 
already in voluntary compliance with the changes. In addition, the rule 
affects the Coast Guard and its staff in the MSC and CG-ENG. The rule 
impacts an estimated six civilian engineers and six military engineers.
Summary of Changes Adopted for the Final Rule
    In this final rule, the Coast Guard adopts the changes included in 
the NPRM, which update the codified references to standards 
incorporated by reference in subchapter F with their more recent 
editions. More specifically, the changes in the final rule fall into 
three categories: (1) editorial changes to the CFR, (2) technical 
updates to standards incorporated by reference, and (3) compliance 
alternatives to standards incorporated by reference. Based on data from 
industry, the Coast Guard assumes industry already uses the more recent 
standards referenced in the rule.
    First, this final rule makes editorial changes to 46 CFR subchapter 
F (parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63 and 64) that 
include such items as the removal of outdated terminology and the 
consolidation of text. These changes have no costs or cost savings 
associated with them.
    Second, this rule updates standards incorporated by reference 
throughout subchapter F. Because no resources are required, and because 
they have already been adopted voluntarily by manufacturers, these 
changes have no cost associated with them.
    Third, this rule amends the regulatory text in 46 CFR 58.10-5(d)(1) 
and 61.10-5(g) impacting compliance alternatives for vessel and 
facility owners or operators. The changes reflect the addition of one 
compliance alternative and the removal of another. This change results 
from the discontinuation of a standard incorporated by reference that 
is the basis of the compliance alternative. (Please see Section IV.D. 
in the preamble under the discussion, ``Part 61--Periodic Tests and 
Inspections,'' and further details in the ``Cost Savings'' portion of 
this RA.) These changes provide regulatory flexibility for the 
regulated public. The final rule imposes no additional costs on 
industry, and the addition of a compliance alternative in Sec.  61.10-
5(g) may save the regulated public money and generate cost savings for 
vessel and facility owners or operators if they choose to use this 
compliance alternative.
    The final rule promotes 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 in 46 CFR subchapter F. Readers may consult the preamble of 
this rule for a general summary of the changes.
    The final rule adopts the regulatory changes in the proposed rule. 
Additionally, based on feedback from the public during the comment 
period, the rule reorganizes 46 CFR 56.60-1(a)(2) and adds 46 CFR 
56.60-1(b) for the purpose of regulatory clarity. These changes are 
editorial in nature and do not impose costs on or crea
