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valves, and fittings, for various types of vessels; adds a limited number of alternative standards; and eliminates outdated or unnecessarily prescriptive regulations.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.

B. Standards Incorporated by Reference To Be Updated or Added

Following this paragraph, we include an alphabetical list of the standards we propose to update or add, each with a listing of the sections in which they appear in Title 46 of the CFR. For each standard listed, we describe the topics covered by the standard, the proposed changes to the standard, any difference between the older edition of standards currently included within the CFR via incorporation by reference (IBR) and the edition proposed for adoption, and a list of subparts or sections that reference the standard.

• American Bureau of Shipping (ABS) standard ABS Rules for Building and Classing Marine Vessels, 2020, Part 4, Vessel Systems and Machinery. This standard updates the 2003 standard, incorporated by reference in §§ 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.

• American Boat and Yacht Council (ABYC) standard ABYC P-1-14, Installation of Exhaust Systems for Propulsion and Auxiliary Engines (2009 standard reaffirmed 2014). This standard updates the 1973 standard, incorporated by reference at § 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.

• ANSI Z21.22-2015, Relief valves for hot water supply systems. This standard updates the 1986 edition incorporated by reference at § 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.

• API Recommended Practice 14C, Analysis, Design, Installation, and Testing of Safety Systems for Offshore Production Facilities, Eighth Edition, February 2017. This standard updates the 1986 edition, incorporated by reference in § 58.60-9. The updates made to the standard are editorial in nature.

• API STD 53, Well Control Equipment Systems for Drilling Wells, fifth edition. This standard replaces API Recommended Practice 53 (API RP 53), the second edition of which is currently incorporated by reference at § 58.60-7. API STD 53 promotes best safety practices for the oil and gas industry during drilling operations, principally focusing on blowout prevention.

• API STD 607, Fire Test for Quarter-turn Valves and Valves Equipped with Nonmetallic Seats, seventh edition (2016). This standard replaces the fourth edition of API STD 607 (1993), incorporated by reference at § 56.20-15. This standard specifies fire type-testing of valves that contain nonmetallic materials and pressure-containing capabilities after the fire test.

• ASME Boiler and Pressure Vessel Code, Section I, Rules for Construction of Power Boilers (2019 edition). The 2001 edition is currently incorporated by reference at §§ 52.01-2, 52.01-5, 52.01-50, 52.01-95, 52.01-100, 52.01-105, 52.01-110, 52.01-115, 52.01-120, 52.01-135, 52.01-140, 52.01-145, 52.05-1, 52.05-15, 52.05-20, 52.05-30, 52.05-45, 52.15-1, 52.15-5, 52.20-1, 52.20-25, 52.25-3, 52.25-5, 52.25-7, 52.25-10, 56.15-1, 56.20-1, 56.60-1, 56.70-15, 56.95-10, 58.30-15, and 59.10-5. By means of this rule, we propose to remove the references at §§ 56.20-1 and 56.70-15. This portion of the ASME Boiler and Pressure Vessel Code (BPVC) provides rules for construction of power boilers, electric

boilers, miniature boilers, and high temperature water boilers to be used in stationary service and includes power boilers used in locomotive, portable, and traction service. Every two years, the code is 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 boilers. Incorporating the latest edition simplifies regulatory compliance and ensures the latest industry practices based on changes in technology are addressed and the highest possible level of safety is required. The 2019 standard updates the code by developing a new non-mandatory appendix for fabrication of dissimilar metal welds for creep strength enhanced ferritic steel to austenitic materials, rewriting section PW-38, incorporating non-mandatory appendix A-100, including detailed rules for preheating and inter-pass temperatures and interruption of welding and preheat, and adding a new figure for code jurisdictional limits for piping for fire-tube boilers.

• ASME Boiler and Pressure Vessel Code, Section IV, Rules for Construction of Heating Boilers (2019 edition). The 2004 edition is currently incorporated by reference at §§ 53.01-3, 53.01-5, 53.01-10, 53.05-1, 53.05-2, 53.05-3, 53.05-5, 53.10-1, 53.10-3, 53.10-10, 53.10-15, and 53.12-1. This code contains requirements, specific prohibitions, and non-mandatory guidance for construction of heating boilers. 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 code updates Section IV by adding stress values to Table HF-30001 and adding language to various parts to allow for electronic signatures.

• ASME Boiler and Pressure Vessel Code, Section VII, Recommended Guidelines for the Care of Power Boilers (2019 edition). The 2001 edition is currently incorporated by reference at §§ 59.01-2. This code contains requirements, specific prohibitions, and non-mandatory guidance for construction of power boilers. 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 operating, maintaining, examining, and care of power boilers. Incorporating the latest editions ensures compliance with current industry practices. The changes made to the standard are structural and stylistic. ASME Boiler and Pressure Vessel Code, Section VIII, Rules for Construction of Pressure Vessels (2019 edition). The 1998 edition is currently incorporated by reference at §§ 54.01-2, 54.01-5, 54.01-15, 54.01-18, 54.01-25, 54.01-30, 54.01-35, 54.03-1, 54.05-1, 54.10-1, 54.10-3, 54.10-5, 54.10-10, 54.10-15, 54.15-1, 54.15-5, 54.15-10, 54.15-13, 54.20-1, 54.20-3, 54.25-1, 54.25-3, 54.25-8, 54.25-10, 54.25-15, 54.25-20, 54.30-3, 54.30-5, 54.30-10, 56.15-1, 56.20-1, 56.25-5, 56.30-10, 56.30-30, 56.60-1, 56.60-2, 56.60-15, 56.95-10, 58.30-15, 59.10-5, and 59.10-10. By means of this rule, we propose to remove the references at §§ 54.01-15, 56.20-1, and 56.30-30. The 1989 edition is also incorporated by reference at §§ 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 § 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.

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.

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).

Modifying paragraph (e) by removing references to specific paragraphs and instead referring to the entire subpart.

Section 56.15-1 Pipe Joint Fittings

Removing text in paragraph (c)(2) that is already adequately 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.

Section 56.20-15 Valves Employing Resilient Material

Deleting text that is no longer required and simplifying text to reflect current policy employed by the MSC to evaluate these types of valves. Overall, these valves are not required anywhere on ships, and this section only

delineates the requirements for when they are installed.

Section 56.25-10 Flange Facings

Removing paragraph (b) as no longer necessary.

Section 56.25-20 Bolting

Removing unnecessary text in paragraphs (b) and (c).

Section 58.16-10 Approvals

Deleting the requirement in paragraph (a) that gas-consuming appliances be “of a type approved” by the Commandant. The requirement 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 installations are reviewed case by case, “acceptance” allows for more flexibility than “approval” when evaluating the overall installation for compliance.

Deleting paragraph (b) of this section as unnecessary.

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

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 CO
2
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 §§ 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

Updating address and options for item submittals.

Section 63.25-9 Incinerators

Modifying paragraph (a) to update address and options for application for type approval of shipboard incinerators.

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.

Table 2—Summary of the Proposed Rule's Impacts

Category
Summary

Affected Population
Vessel owners and operators, shipyards, builders and manufacturers of vessels and vessel components, the Coast Guard (Marine Safety Center (MSC) and United States Coast Guard Commercial Regulations and Standards Directorate (CG-5PS)). Class societies and vessel insurers may have some interest.

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 rate)
$9.787 million (10-year 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.

Note:
These data are based on Coast Guard data found in the Marine 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.
