III. Background, Basis, and Purpose

    This notice of proposed rulemaking (NPRM) 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; 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standards; and eliminates outdated or unnecessarily prescriptive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 of safety for 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 United States Coast Guard has statutory authority to promulgate
regulations under Title 43, United States Code (U.S.C.), section
1333(d); and Title 46 U.S.C. 3306 and 3703, and the Department of
Homeland Security Delegation No. 0170.1, which delegates authority
under these statutes to the Commandant of the Coast Guard. 43 U.S.C.
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. 46 U.S.C. 3306(a)(1) authorizes the Secretary to prescribe
regulations for the design, construction, alteration, repair, and
operation of vessels subject to inspection, including equipment,
appliances, propulsion machinery, auxiliary machinery, boilers, unfired
pressure vessels, piping, and electric installations. Additionally, 46
U.S.C. 3703(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 enhanced protection of the marine environment.

IV. Discussion of Proposed Rule

A. General Discussion

    In general, the proposed rule would make the following changes:
    1. Corrections--we would amend several sections to correct
inadvertent errors or deletions. We would also remove material that is
obsolete or superfluous to an efficient and effective marine safety
regulatory scheme, and update contact information for Coast Guard
offices and standards organizations.
    2. Stylistic Revisions--we would 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, and standardizing terms that were variously
presented as compound words, hyphenated constructions, or multi-word
phrases using the format preferred by the Government Publishing Office
(GPO).
    3. Updated cross references--we would update cross references to
reflect the relocation, within the CFR, of pertinent provisions. We
would 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 would 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 the American Bureau of Shipping (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 \1\ and have been delegated the authority to perform certain
functions and certifications using their respective class rules for
vessels enrolled in the Alternate Compliance Program. For vessels not
enrolled in the Alternate Compliance Program, 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. The following table indicates the sections we propose to
amend, and why.

Sec. Sec.  64.5, 64.11, 64.13, 64.21, 64.25, and 64.31, and reference
is made to the use of a constant from the 1974 edition in a calculation
at Sec.  64.63. However, these earlier editions would remain unchanged
within the CFR, as part 64 is applicable only to marine portable tanks
for which the Coast Guard's Marine Safety Center (MSC) received an
application on or before May 1, 1991. This code contains requirements,
specific prohibitions, and non-mandatory guidance for construction of
pressure vessels. It has been regularly revised to accommodate
technological developments, to address administrative requirements, to
incorporate interpretations, and to clarify the intent of the code. It
is the internationally accepted authoritative standard for design and
construction of heating boilers. Incorporating the latest editions
ensures compliance with current industry practices. The 2019 edition
allows for additional design methods from Div. 2 to be used in Div. 1
by creating new appendix 46. Revisions were also made for clarity.

57.04-1, 57.05-1, 57.06-1, 57.06-3, 57.06-4, and 59.10-5. By means of
this rule, we propose to newly incorporate this standard at Sec.
56.85-10 and to remove the references at Sec. Sec.  57.01-1, 57.02-3,
and 57.06-3. This standard establishes the qualifications of welders,
welding operators, brazers, and brazing operators and the procedures
employed in welding or brazing, and has been regularly revised to
accommodate technological developments, address administrative
requirements, incorporate interpretations, and clarify the intent of
the code. It is the internationally accepted authoritative standard for

throughout all of part 52, as BPVC is recognized as the appropriate
acronym for the ASME Boiler Pressure Vessel Code.
Section 52.01-52.25 Power Boilers
    Modifying various paragraphs to delete text already addressed in
ASME BPVC.
Section 52.01-3 Definitions
    Deleting definitions listed in this section but not currently used

Section 52.25-3 Feedwater Heaters (Modifies PFH-1)
    Modifying various paragraphs in this section to delete references
and text already addressed by the ASME BPVC or that are otherwise
outdated.
Part 53--Heating Boilers
    Replacing the words ``boiler pressure vessel code'' with ``BPVC''
throughout part 53, as BPVC is recognized as the appropriate acronym
for the ASME Boiler Pressure Vessel Code.
Section 53.01-10 Service Restrictions and Exceptions (Replaces HG-101)
    Modifying paragraph (d) to remove exact temperature requirements
and retaining a temperature range that would benefit industry.
    Modifying paragraph (e)(1) to provide correct citation for the ASME
BPVC stamping and provide cites to the IBR.
Part 54--Pressure Vessels
    Replacing the words ``boiler pressure vessel code'' with ``BPVC''
throughout all of part 54, as BPVC is recognized as the appropriate
acronym for the ASME Boiler Pressure Vessel Code.
Section 54.01-1 Incorporation by Reference
    Modifying paragraphs (b), (d), and (e) to update the addresses for
the American Society of Mechanical Engineers (ASME), the Compressed Gas
Association (CGA), and the Manufacturers Standardization Society of the
Valve and Fittings Industry (MSS), respectively.
Section 54.01-15 Exemptions From Shop Inspection Plan Approval
(Modifies U-1(c)(2))
    Deleting paragraph (a)(3)(i) because this section deals with
internal pressure and the reference cited deals with external pressure.
Section 54.01-18 Plan Approval
    Editing paragraph (a) to provide reference to new proposed
paragraph (c).
    Adding paragraph (c) to identify which plans for Class I, II, and
II pressure vessels are not required to be submitted for approval.
Section 54.10-3 Marine Inspectors (Replaces UG-90 and UG-91, and
Modifies UG-92 Through UG-103)
    Editing the section heading to make it easier to find the
regulation requiring stamping of the Coast Guard Symbol. The
requirement for use of the Coast Guard Symbol on pressure vessels is
often misunderstood.
    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 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).
Part 56--Piping Systems and Appurtenances
Section 56.07-5 Definitions
    Clarifying the definition for ``piping schedule'' and deleting the
definition for ``plate flange,'' as it does not require a definition.
Section 56.07-10 Design Conditions and Criteria (Modifies 101-104.7)
    Modifying paragraph (b) by deleting the last sentence within the
parentheses. It is not necessary to refer to definitions in part 52 for
this paragraph.
    Modifying paragraph (d) by deleting text that was inadvertently
repeated.
    Modifying paragraph (e) by removing references to specific
paragraphs and instead referring to the entire subpart.

addressed by the incorporated ASME industry standard.
Section 56.15-5 Fluid-Conditioner Fittings
    Deleting text in paragraph (c), nonstandard fluid conditioner
fittings, that is already adequately addressed by paragraph (b);
generally, fluid conditioner fittings must meet the requirements of
this section regardless of whether they are `standard' or
`nonstandard', and must be appropriate for the fluid contained, and the
temperature and pressure of the system. In addition, with advancements
in manufacturing, there is no need to reference part 54 (pressure
vessels), for fluid conditioner fittings in current paragraphs (c) and
(d).
Section 56.20-1 General
    Removing text that is redundant and that can be adequately replaced
by the incorporated ASME standard.
Section 56.20-9 Valve Construction
    Modifying paragraphs (a), (b), (c), (e), and (g) to reflect
advancements in valve design technology and to remove text adequately
addressed already by the incorporated ASME standard.

or is otherwise adequately addressed already by the incorporated
standards in part 56.
Section 56.35-10 Nonmetallic Expansion Joints
    Removing the reference to part 50, as the appropriate standards are
listed already in this part.
Section 56.35-15 Metallic Expansion Joints
    Removing the reference to part 50, as the appropriate standards are
listed already in this part.

that the Commandant specifically ``approve'' all types of gas-consuming
appliances is not necessary, given that appliances must already be
tested and listed by third party laboratories and meet the additional
requirements of Subpart 58.16.
    Changing the word ``approved'' to ``accepted'' in paragraph (c).
Because this paragraph refers to another government agency's
requirements for safety-relief devices, and shipboard appliance

Section 58.25-85 Special Requirements for Tank Vessels
    Deleting certain text in paragraph (c)(1) and (2) of this section
as unenforceable.
    Deleting paragraph (g), because this paragraph is applicable only
to tank vessels of 40,000 gross tons or more constructed before 1984.
Virtually all of those vessels have been phased out of service due to
the pollution prevention requirements in 33 CFR 157 for ``double
hulls'' on tank vessels.
Section 58.30-1 Scope
    Deleting certain text in paragraph (a) as not applicable.
Section 58.30-15 Pipe, Tubing, Valves, Fittings, Pumps, and Motors

    Modifying paragraph (b) to update the name and address of ASTM
International.
Section 61.05-10 Boilers in Service
    Eliminating unnecessary and outdated text regarding boiler
inspections from paragraphs (a) and (f).
Section 61.10-5 Pressure Vessels in Service
    Modifying paragraph (g) to provide inspection compliance options,
in lieu of the hydrostatic test currently required by this paragraph,
for bulk storage tanks containing refrigerated liquefied CO2
for use aboard a vessel as a fire-extinguishing agent. The inspection
options consist of performing a hydrostatic test or having the option
of an internal inspection. This is further explained in the regulatory
language.
Part 62--Vital System Automation
Section 62.05-1 Incorporation by Reference
    Modifying paragraph (b) to update the address for the American
Bureau of Shipping (ABS).
Section 62.35-50 Tabulated Monitoring and Safety Control Requirements
for Specific Systems
    Deleting the requirements for main propulsion boiler supply casing
and uptakes, burner flames, control power, and burner valves in Table
62.35-50. These components are required to comply with the same
requirements in Section 4-9-6 of the ABS Marine Vessel Rules (2020),
which is proposed to be referenced in this table.
    Modifying the requirements for ship service generators in Table
62.35-50. Currently, compliance with the ABS Steel Vessel Rules for
propulsion boilers and propulsion diesel engines is required. The
requirements for auxiliary generators in Section 4-9-6 of the ABS
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.
Section 62.50-30 Additional Requirements for Periodically Unattended
Machinery Plants
    Revisions are made to paragraphs (c), (d), (h), and (k) to reflect
correct verbiage and to provide clarity.
Part 63--Automatic Auxiliary Boilers
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 of the CFR and do not belong in Part 63
for Automatic Auxiliary Boilers.
Section 63.05-1 Incorporation by Reference
    Modifying paragraphs (b) and (c) to update the name and address for
the ANSI and ASME, respectively.
Section 63.10-1 Test Procedures and Certification Report

    Adding IMO MEPC.244(66) as an accepted 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.
Section 64.2 Incorporation by Reference
    Modifying paragraph (b) to update the address for the ASME.

V. Incorporation by Reference

    Material proposed 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. For information about how
to view this material, see the ADDRESSES section of this preamble.
Copies of the material are also available from the sources listed in 46
CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63, and 64. Before
publishing a binding rule, we will submit this material to the Director
of the Federal Register for approval of the incorporation by reference.

VI. Regulatory Analyses

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

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 costs and
benefits, reducing costs, harmonizing rules, and promoting flexibility.
    The Office of Management and Budget (OMB) has not designated this
proposed rule a significant regulatory action under section 3(f) of
Executive Order 12866. Accordingly, OMB has not reviewed it.
    The Coast Guard proposes to update subchapter F of Title 46 of the
CFR. This proposed rule would align the standards on U.S.-flagged
vessels of vessel types of subchapter F with current industry practices
to ensure that regulatory standards are current, and the changes would
harmonize regulatory requirements with current industry standards. The
majority of the updates simply would 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 would
correct regulatory language and remove redundant and outdated
references. The Coast Guard believes there are no additional costs
associated with this proposed rule. The Coast Guard estimates this rule
will save the regulated public and federal government approximately
$9.787 million over the 10-year period of analysis at 7% in 2020
dollars.
    The following regulatory analysis (RA) provides an evaluation of
the economic impacts associated with this proposed rule. Table 2
provides a summary of the proposed rule's costs and benefits.

Costs................................  None. The proposed rule would not
                                        increase costs of compliance for
                                        the regulated public or the
                                        Coast Guard because no
                                        additional requirements are
                                        being proposed.
Cost Savings (7-percent discount       $9.787 million (10-year
 rate).                                 discounted cost savings),
                                        annualized cost savings: $1.385
                                        million in 2020 dollars.
Unquantified Benefits................  Clarity of regulatory intent
                                        through stylistic changes and
                                        corrections, harmonization of
                                        regulatory requirements with
                                        current industry standards,
                                        better utilization of Coast
                                        Guard human resources,
                                        compliance with Presidential
                                        Regulatory Reform Initiative
                                        (March 4, 1995).\2\
------------------------------------------------------------------------

    This proposed rule has two main goals. First, the Coast Guard
intends it to update design standards that appear in the CFR by
incorporating by reference more recent industry standards. Second, the
proposed rule would provide clarity and simplify regulatory compliance
for industry by removing obsolete regulations and revising current
regulatory text, including the correction of errors.
---------------------------------------------------------------------------

    \2\ The proposed rule would continue the Coast Guard's response
to the Presidential Regulatory Reform Imitative 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 proposed rule would 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 proposed rule would encourage the use of newer
equipment and promote adherence to modern standards in the industry.
---------------------------------------------------------------------------

Affected Population
    The Coast Guard analyzed this rulemaking to determine the affected
population and how the proposed rule would impact vessel owners and
manufacturers.\3\ The proposed revisions affect a variety of vessel
owners and operators; including those owning cargo vessels, passenger
vessels, nautical school vessels, tank vessels, and tank barges. Some
potentially impacted vessel owners and operators include nonprofits and
Tribal/State/local government entities.\4\ Because the proposal impacts
only new vessels or those undergoing major conversions, the Coast Guard
estimates that fewer than 200 vessels would be impacted annually.\5\
---------------------------------------------------------------------------

    \3\ Class societies and vessel insurers may have interest in the
rule. However, no actions are required by them directly or
indirectly as a result of the rule.
    \4\ Public vessels are excluded.
    \5\ Based on input from Coast Guard subject matter experts in
the Directorate of Commercial Regulations and Standards who are
tasked with relevant duties.
---------------------------------------------------------------------------

    An estimated 16,148 vessels owned by 6,437 owners and operators
would be impacted potentially, but the vessel owners and operators
would be impacted directly only if they procured a new vessel or
engaged in a major conversion of an existing vessel under conditions as
specified in the proposal. Large self-propelled vessels, which are
covered by more provisions of Subchapter F than smaller vessels and
barges, would be more likely to be impacted. The following table
details those vessels potentially impacted by the proposed rule.

  Information for Safety and Law Enforcement (MISLE) database.

    The proposed rule also would impact businesses involved in vessel
manufacturing. There are approximately 1,022 shipyards and
manufacturers of vessels or vessel components in the affected
population; however, vessel manufacturers are believed to already be in
voluntary compliance with the proposed changes. In addition, the
proposal would impact the Coast Guard and its staff in the MSC and CG-
5PS. An estimated six civilian engineers and six uniformed personnel
potentially would be impacted.
Summary of Changes
    Generally, the Coast Guard proposes to update codified references
to standards incorporated by reference in subchapter F with their more
recent editions. These more recent standards would provide more clarity
and specificity than the outdated standards they would be replacing.
More specifically, the Coast Guard segments the effect of the proposed
changes 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 proposal. Table 4
summarizes the regulatory changes.
    First, for the proposed changes to update standards incorporated by
reference, this proposed rule would make editorial changes to
subchapter F that include such items as the removal of outdated
terminology and the consolidation of text. These proposed changes would
include 46 CFR parts 50, 52, 53, 54, 56, 57, 58, 59, 61, 62, 63 and 64.
The Coast Guard expects these changes would have no costs, cost
savings, or benefits.
    Second, this proposed rule updates standards incorporated by
reference throughout subchapter F. Because no resources are required,
and because they have been adopted voluntarily already by
manufacturers, the Coast Guard expects these changes would have no
cost.
    Third, this proposed rule would amend the regulatory text in 46 CFR
58.10-5(d)(1) and 61.10-5(g) that impacts compliance alternatives for
vessel owners and operators. The changes reflect the proposed addition
of a compliance alternative and the proposed removal of a compliance
alternative. This proposed change results from the discontinuation of a
standard incorporated by reference that is the basis of the compliance
alternative. (Please see the preamble in the proposed changes to ``Part
61--Periodic Tests and Inspections,'' and further detailed in the Cost
Savings portion of this RA.) These proposed changes provide regulatory
flexibility for the regulated public. No additional cost would be
incurred, and the addition of a compliance alternative may save money.
The proposed rule's replacement of a compliance alternative would offer
an option which has lower costs associated with it. This would be a
cost savings for vessel owners if they choose to use this compliance
alternative.
    The proposed rule would create consistency between Coast Guard
regulations and national and international standards through
incorporation by reference, provide options with alternative standards,
eliminate obsolete standards, and clarify the existing requirements
through the changes proposed in 46 CFR subchapter F. Table 4 lists
these proposed changes by type of change. Readers may consult the
preamble of this NPRM for a general summary of the proposed changes.

    \6\ Please refer to the preamble and Table 1 for a complete
accounting of affected paragraphs, including redesignations.
    \7\ This list is not exhaustive. Please see Table 1 for the full
list.
    \8\ Please see Table 1 for complete list.
    \9\ The proposed change would give operators the option of
undergoing an internal inspection every 10 years as opposed to
requiring a hydrostatic test every 10 years.
    \10\ UL 1111 has been withdrawn and no longer exists; therefore,
it can no longer be included as an option for regulation compliance.
