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valves, and fittings, for various types of vessels; adds a limited number of alternative standards; and eliminates outdated or unnecessarily prescriptive regulations.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

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).

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 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.

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 §§ 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

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

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.

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.

Affected Population

The Coast Guard analyzed this rulemaking to determine the affected population and how the proposed rule would impact vessel owners and manufacturers. 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. 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.

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.

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.

Data Input for Calculations

This RA uses multiple data sources. To estimate the duration of tasks, the Coast Guard used previous OMB-approved collections of information. These collections of information were previously vetted publicly and provide guidance on estimates of tasks such as communicating information and education. The RA also uses estimates from Coast Guard subject matter experts.

To calculate wage rates, the Coast Guard used two publicly available sources for wage data: the U.S. Department of Labor Bureau of Labor Statistics (BLS) Occupational Employment Statistics and the Commandant Instruction entitled “Reimbursable Standard Rates” (commonly called Commandant Instruction U). For positions outside the Coast Guard, the Coast Guard used publicly available data of the BLS Occupational Compensation Survey to estimate wage rates for positions that would be impacted by the proposed rule. For Coast Guard positions, the Coast Guard used publicly available and publicly vetted information found in Commandant Instruction U and the U.S. Office of Personnel Management pay chart for the Washington, DC locality pay area for 2020 to estimate the wage data.

From the wage data obtained in the previous step, the Coast Guard used a loaded labor rate to estimate the actual cost of labor to employers. The load factor (or benefits multipliers) for the regulated public and Coast Guard civilian workers was obtained using BLS data. To account for an employee's non-wage benefits, the Coast Guard applied a load factor to the unloaded mean hourly wage rate; data of the BLS's “Employer Cost for Employee Compensation” database were used for the regulated public's wages. The Coast Guard determined the load factor to be about 1.49, rounded. For Coast Guard civilian positions, the load factor was determined to be approximately 1.75, rounded. For Coast Guard uniformed positions, the Coast Guard used data that already had applied the load factor, so such an adjustment was not necessary. These figures were used to estimate the reasonable and customary average labor cost to employers. Table 5 displays the labor categories, the source of the wage rates, the total compensation, the wage rates, and the calculated load factor. We estimated the load factor for the applicable occupation category by dividing the total compensation by the hourly wage rate.

The Coast Guard assumed a constant wage rate and a constant duration for tasks for the period of annualization. Likewise, the estimates are based on 2020 dollars. Table 6 presents the estimated hourly loaded wage rates for the proposed rule.

Using the BLS “Occupational and Employment Statistics” database and May 2019 wage estimates, the unloaded mean hourly wage rate for marine engineers and naval architects (occupational code 17-2121) is $47.88. The Coast Guard multiplied $47.88 by the load factor of 1.49 to obtain a loaded mean hourly wage rate of about $71.23 for this occupation. The hourly rate for a manager (occupational code 11-3051) of $56.82 was estimated to be $84.52 after the load factor application.

For all provisions related to the Government, the Coast Guard used publicly available data as found in Commandant Instruction U to estimate wage rates for Coast Guard employees. Labor costs attributed to the Government are estimated for Coast Guard civilian and uniformed engineers and supervisors of CG-5PS and the MSC. Hourly loaded labor costs for civilians are estimated for a GS-14 engineer at $115.51 and for a GS-15 engineering supervisor at $135.87. For uniformed engineers, the Coast Guard used an average of $91 for engineers at the O-3 (Lieutenant) and O-4 level (Lieutenant Commander) because both would work on the task. The wage rate for a uniformed supervisory engineer is estimated to be $111 for an O-5 (Commander). These figures represent a wage rate with a fully-loaded labor factor of 1.85 for uniformed Coast Guard positions. Table 6 presents a summary of the data used.

Costs

The Coast Guard estimates there are no costs associated with this proposed rule. The proposed rule does not require actions of manufacturers or vessel owners and operators. The proposal is not retroactive, and existing vessels are not required to be retrofitted.

This proposed rule would not require owners and operators to acquire any standards incorporated by reference; they would not need the standard in hand to be in compliance. Owners and operators only would need to look for evidence from manufacturers that vessels meet or exceed the standard before purchase; such evidence could be found in a contract for purchase or repair of a vessel or in product documentation such as a user guide or warranty information. For these reasons, the Coast Guard has not included a cost for the procurement of the newer standards for vessel owners.

The Coast Guard estimates that the regulated public (manufacturers) are currently in voluntary compliance with the requirements proposed by the rule based on manufacturer participation in the development of industry standards. When industry standards are promulgated, they undergo a process of review and comment by the industry. Input from manufacturers is key to developing new standards that consider the engineering capabilities of manufacturers. After the review and comment process, the newer standard is voted upon at the various governing bodies' committee meetings, and manufacturers are among those voting. For this reason, the Coast Guard believes manufacturers are aware and knowledgeable about the newer standards. Given this, we further assume they already would own copies of the standards. For this reason, the Coast Guard has not computed a cost for them to procure the standards incorporated by reference. The Coast Guard requests public comment on our assumption of voluntary compliance with the proposed rule.

Manufacturers already have been producing equipment to meet the standard and typically will begin to make manufacturing modifications even before such changes are adopted formally. Therefore, the Coast Guard does not anticipate that there would be costs to retrofit manufacturing equipment to be in compliance with the proposed rule. For previous similar rulemakings, no manufacturer commented that it would experience incremental costs of production to comply with newer editions of standards incorporated by reference. For these reasons, the Coast Guard has not included a cost for these provisions. However, the Coast Guard acknowledges that there is a non-zero probability that some manufacturer may need to purchase a newer standard. The estimated incremental cost to do so varies according to which standard is needed.

Cost Savings to the Regulated Public

The proposal would result in cost savings to the regulated public and the Coast Guard from a reduction in labor for processing equivalency tests and no longer requiring labor to have education on the older standards incorporated by reference. The Coast Guard expects this proposed rule would generate cost savings for owners and operators who no longer would need to request a waiver of subchapter F regulatory requirements, known as an equivalency test request, from the MSC.

Generally, the reason an owner or operator makes an equivalency request is to seek a determination from the Coast Guard on whether an edition of an industry standard not codified in the CFR is sufficient for use. To draft an equivalency request, an owner or operator would have material prepared by its engineering staff or by a contracted engineering firm.

Based on MSC and CG-5PS data, the Coast Guard receives approximately 200 equivalency requests annually. The Coast Guard estimates it takes a marine engineer or naval architect employed by a vessel owner approximately 40 hours of time to develop an equivalency request and submit it to the Coast Guard for review. An estimated 0.5 hour would be used by a supervisor engineer to approve the work. The request for an equivalency test is sent via email to the MSC. Given that the submittal is via email, the Coast Guard has not estimated postage costs.

In addition, the regulated public would realize cost savings from the avoided cost of education for maintaining situational awareness on the existing standards incorporated by reference which the proposal would eliminate. The Coast Guard estimates that 0.5 hour is spent annually by engineers on education necessary to familiarize or re-familiarize themselves with these standards. The Coast Guard believes that, as industry standards evolve and advance, older editions may not be readily accessible, even if they are incorporated by reference into the CFR. As such, we expect that engineers will find the older standards and read them on occasion to maintain an awareness of how these standards are different from current industry standards.

In 2020, the Small Business Administration (SBA) published a rule where it determined that roughly 2,500 small disadvantaged businesses would save 0.5 hours each by no longer having to read 16 outdated regulations that SBA was removing through the rulemaking project. Given that this proposed rule relates to a similar subject matter—time saved from the removal of outdated or redundant regulations—the Coast Guard assumes a similar duration would be saved by industry employees. This 0.5 hour is a savings to vessel owners and operators and to manufacturers.

Cost Savings to the Coast Guard

The Coast Guard also would experience cost savings as a result of the proposed rule. When the Coast Guard receives an equivalency request from a vessel owner or operator, a Coast Guard engineering staff member at the MSC must review the request to provide a determination on whether the proposed standard(s) is equivalent to the existing standard(s) found in subchapter F. The Coast Guard MSC engineer needs approximately 32 hours to review an equivalency request, followed by 0.5 hours of supervisor review. In a small percentage of more complex cases, the MSC works with CG-5PS engineering staff to complete the equivalency review. Following review, MSC emails a decision back to the owner or operator. The Coast Guard estimates it reviews 200 equivalency requests annually. To calculate the costs avoided by Coast Guard no longer processing equivalency requests, we multiplied the number of annual equivalency requests by the sum of the duration of initial review, review, and supervisor review multiplied by the loaded wage rates of the respective Coast Guard personnel performing the review (200 equivalency requests × (1 hour × average wage rate for uniformed engineer + 32 hours × wage rate for civilian engineer + 0.5 hours × wage rate for civilian engineering supervisor)).

In addition, the Coast Guard would save labor costs annually, since staff would no longer need to maintain an awareness of the older versions of standards that are incorporated by reference. The proposal eliminates and replaces them with newer standards. The Coast Guard estimates that 0.5 hour annually is spent on education on the older standards by an employee tasked with working on equivalency requests. In the aforementioned SBA proposed rule, the agency claimed that about 760 Federal contracting officers per year would save 0.5 hours from no longer reading outdated standards that were being removed by the rule. We therefore estimate 0.5 hours of education is similarly needed for Coast Guard personnel to maintain awareness and knowledge of older standards. This applies to six civilian engineers and six uniformed engineers who work on equivalency requests. To calculate the costs avoided by Coast Guard personnel no longer requiring education on outdated standards, we multiply 0.5 hours by the hourly wage rates of the Coast Guard personnel (0.5 hours (6 uniformed engineers × average wage rate for uniformed engineer + 6 civilian engineers × wage rate for civilian engineer)).

Table 7 presents the estimated cost savings of the proposed rule to the regulated public and to the Coast Guard.

Table 8 summarizes the cost savings per year of the proposed rule for the regulated public and the Federal Government

The Coast Guard estimates an annualized cost savings to industry of $0.622 million (with a 7-percent discount rate) and an annualized cost savings to Government of $0.772 million (with a 7-percent discount rate) for a total annualized cost savings of $1.393 million in 2020 dollars.

Cost Savings

The proposed rule amends existing regulations in 46 CFR subchapter F. The proposed amendments would eliminate confusion caused by outdated and conflicting rules on marine engineering safety of various vessel components and systems and give the maritime industry clear instructions on how to comply with regulations. Moreover, this proposed rule would amend existing regulations to reflect current national and international standards. The proposed rule also would result in cost savings to the regulated public and the Federal Government, as noted further.

Several of the proposed rule's changes have no cost effects (please see Table 4). These editorial changes, such as the removal of outdated terminology and the consolidation of text, would not result in cost savings but would clarify regulations, as noted earlier. Also, by incorporating the newer standards, the proposed changes would provide clarity and specificity. For these changes, the Coast Guard expects them to have no direct cost savings because they are unseverable from the cost savings noted previously.

The compliance alternatives would remove overly prescriptive requirements, simplify regulatory compliance, and provide regulatory flexibility for industry. The proposal would add a compliance alternative to hydrostatic tests, thereby allowing the regulated public to perform an internal inspection in lieu of the hydrostatic test. The proposed inclusion of this compliance alternative would save a given vessel owner labor and material. In order to comply with the existing requirement for hydrostatic tests, the vessel owner must remove existing lagging around the unit, then replace it once the test is completed. The proposed compliance alternative would involve less labor and would not necessitate the removal and replacement of lagging as the existing requirements do. The Coast Guard has not estimated a cost for this alternative, because it is unknown how many vessel owners would choose to pursue the alternative. Because equipment sizes vary, the amount of labor and material needed to comply now and under the alternative is also unknown. The Coast Guard invites public comment on this issue.

Alternatives Considered

Within the Coast Guard's development of this proposed rule, significant alternatives to the regulatory component(s) were considered to determine if any alternative could accomplish the stated objectives of applicable statutes and could minimize any significant economic impact of the rule on small entities beyond the proposed rule. Among these alternatives were the following:

Alternative 1: Take No Action

The Coast Guard could have chosen not to pursue the rulemaking. Taking no action would cause no incremental costs to regulated entities nor to the Coast Guard. However, in doing nothing, the Coast Guard would have no mechanism to update regulations to reflect current practices and improve their relevance to the public. There would be neither an increase nor decrease in benefits to regulated entities due to the alternative. The proposed rule has been estimated to produce quantifiable cost savings to the Coast Guard and the regulated public, which would not be possible under the alternative of no action.

The standards currently incorporated by reference are outdated. To keep them codified would, in theory, maintain existing safety levels. However, because they are so outdated, they are sparsely available. Compliance with them may become problematic in the future due to lack of availability. The older editions of the standards do not contain guidance for several current industry practices. Maintaining the regulations with the existing standards incorporated by reference would not allow for cost savings as the proposal would do.

The goal of this proposed rule is to streamline requirements, to clarify existing rules and to increase enforcement effectiveness. The no-action alternative would result in no additional costs and maintain current levels of public safety. Similarly, the proposed rule is anticipated to have cost savings opportunities; and these savings would not accrue to the public if current regulations were not amended. The proposed rule also is being promulgated to provide clarity on regulatory intentions; a no-action choice would not permit this clarification to be given to the public. This alternative would result in no benefits as there would be no changes to current practice; therefore, the Coast Guard rejected this alternative.

Alternative 2: Delay the Effective Date

The Coast Guard could have delayed the effective date. Delayed effective dates are used to aid in compliance implementation, particularly when the labor costs or capital costs are considerable. The compliance costs for the proposal are zero as noted earlier, and a delayed effective date would delay the cost savings opportunities to all parties. For these reasons, the Coast Guard rejected this alternative.

Alternative 3. Exempt Small Entities

The Coast Guard could have exempted small entities from some or all of the proposed rule's provisions. In principle, an exemption would save small entities time and money to comply with regulations. Exemptions for small entities often are used when costs of compliance, such as capital costs, are high. However, there are no costs of compliance for this proposed rule. For this alternative, an exemption may cause the cost savings opportunities of the rulemaking to be precluded for small entities and, thereby, the total value of the rule's cost savings would decline accordingly.

The proposal would implement requirements for business practices in which the majority (if not all) of small businesses now engage. An exemption for small business entities from the rulemaking would have little effective and practical impact on small business entities. There is a high level of voluntary compliance and limited applicability for the affected population. The costs of compliance are zero and the rule is applicable only if an actionable event occurs (for example, if a new vessel is procured or an existing vessel undergoes a major conversion). For these reasons, the Coast Guard did not pursue an exemption for small entities.

B. Small Entities

The Regulatory Flexibility Act of 1980 (RFA), 5 U.S.C. 601-612, and Executive Order 13272 (Consideration of Small Entities in Agency Rulemaking) requires a review of proposed and final rules to assess their impacts on small entities. An agency must prepare an initial regulatory flexibility analysis unless it determines and certifies that a rule, if promulgated, would not have a significant impact on a substantial number of small entities.

Under the RFA, we have considered whether this proposed rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000.

Based on our analysis, this proposed rule would affect vessel owners and operators, manufacturers and class societies. While the proposed rule excludes public vessels, there exists considerable diversity in the types of vessel owners that may be impacted by the proposal. Some vessel owners potentially impacted by this proposed rule include Tribal, State, and local governments as well as nonprofits including colleges and universities, museums, and science foundations.

The MISLE database maintained by the Coast Guard contains detailed information on the U.S. maritime industry, including vessel and major equipment specific information, and MISLE data suggest that the potentially affected population contains thousands of vessels for thousands of vessel owners and operators. While there exists no exact figure of the population of U.S.-flagged vessels and their owners and operators, and the Coast Guard does not maintain a registry of all vessels, many vessels are documented and therefore there is a record of the owner. For these reasons, the Coast Guard was able to estimate the number of vessel owners and operators impacted by the proposed rulemaking based on the MISLE dataset of U.S.-flagged vessels. The Coast Guard used this dataset of vessels, refined to eliminate duplicate managing owner names, to create a dataset of unique owner names to serve as a proxy for the number of vessel owners in the affected population.

The SBA uses either revenue level or employment size to establish small entity size categories. For that reason, the Coast Guard reviewed publicly available information to determine revenue and employment estimates. These sources included but were not limited to www.manta.com,, www.dnb.com,, and the corporate websites of several businesses. The reader should note that the Coast Guard used data for the governing body of a corporate entity. In other words, for affected business entities that were subsidiaries of another company; the employment size and revenue level of the parent company was compared to the small business size standard for the North American Industry Classification System (NAICS) code of the parent company.

The Coast Guard used a random sample to estimate the number of small entities that are manufacturers and managing owners. The Coast Guard was able to find data on approximately 92 percent of the sampled managing owner businesses and 88.6 percent of manufacturers impacted by the rule. Publicly available data were used to obtain company-specific information such as annual revenues and number of employees. Any company for which the Coast Guard did not find data was considered small. Using the SBA's “Table of Size Standards” and the NAICS codes listed in the table, the Coast Guard found that 21.35 percent of governmental entities that were managing owners of vessels are small entities. For nonprofits, 84.48 percent were small entities. For the remaining companies owning vessels in the affected population, the Coast Guard found that 85.85 percent were small entities. For manufacturers, the Coast Guard estimates that 62.03 percent of companies were small entities.

Cost savings are incurred only under conditions as specified in the proposal. The cost saving for each vessel owner or operator would be approximately $2,923 per entity, which is less than 1 percent of revenue for 72.48 percent of small entity managing owners. These cost savings are incurred only if the regulated entity experienced tasks as noted in the proposed rule. For most vessel owners and operators, there would be no cost nor cost savings from the proposed rule.

Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this proposed rule would not have a significant economic impact on a substantial number of small entities.

If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this rule would have a significant economic impact on it, please submit a comment to docket at the address in the ADDRESSES section. In your comment, explain why you think it qualifies and how and to what degree this rule would affect it economically.

C. Assistance for Small Entities

Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996, Public Law 104-121, we want to assist small entities in understanding this proposed rule so that they can better evaluate its effects on them and participate in the rulemaking. If the proposed rule would affect your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance, please call or email the person in the FOR FURTHER INFORMATION CONTACT section of this proposed rule. The Coast Guard will not retaliate against small entities that question or complain about this proposed rule or any policy or action of the Coast Guard.

Small businesses may send comments on the actions of Federal employees who enforce, or otherwise determine compliance with, Federal regulations to the Small Business and Agriculture Regulatory Enforcement Ombudsman and the Regional Small Business Regulatory Fairness Boards. The Ombudsman evaluates these actions annually and rates each agency's responsiveness to small business. If you wish to comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR (1-888-734-3247).

D. Collection of Information

This proposed rule would not require a modification of an existing collection of information (Plan Approval and Records for Marine Engineering Systems—Title 46 CFR Subchapter F OMB Control Number: 1625-0097) and would not call for new collection of information under the Paperwork Reduction Act of 1995 (PRA), 44 U.S.C. 3501-3520. As defined in 5 CFR 1320.3(c), “collection of information” comprises reporting, recordkeeping, monitoring, posting, labeling, and other similar actions.

E. Federalism

A rule has implications for federalism under Executive Order 13132 (Federalism) if it has a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. We have analyzed this proposed rule under Executive Order 13132 and determined that it is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132. Our analysis follows.

It is well settled that States may not regulate in categories reserved by Congress for regulation by the Coast Guard. It is also well settled that all of the categories regulated under 46 U.S.C. 3306 and 3703, as well as any other category in which Congress intended the Coast Guard to be the sole source of a vessel's obligations, are within the field foreclosed from regulation by the States. See the Supreme Court's decision in United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 120 S.Ct. 1135 (2000). This proposed rulemaking updates the references to incorporated standards in 46 CFR Subchapter F, which is authorized under 43 U.S.C. 1333, 46 U.S.C. 3306, and 46 U.S.C. 3703. Therefore, because the States may not regulate within these categories, this rule is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132.

While it is well settled that States may not regulate in categories in which Congress intended the Coast Guard to be the sole source of a vessel's obligations, the Coast Guard recognizes the key role that State and local governments may have in making regulatory determinations. Additionally, for rules with federalism implications and preemptive effect, Executive Order 13132 specifically directs agencies to consult with State and local governments during the rulemaking process. If you believe this proposed rule has implications for federalism under Executive Order 13132, please contact the person listed in the FOR FURTHER INFORMATION section of this preamble.

F. Unfunded Mandates Reform Act

The Unfunded Mandates Reform Act of 1995, 2 U.S.C. 1531-1538, requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Although this proposed rule would not result in such an expenditure, we do discuss the effects of this proposed rule elsewhere in this preamble.

G. Taking of Private Property

This proposed rule would not cause a taking of private property or otherwise have taking implications under Executive Order 12630 (Governmental Actions and Interference with Constitutionally Protected Property Rights).

H. Civil Justice Reform

This proposed rule meets applicable standards in sections 3(a) and 3(b) (2) of Executive Order 12988, (Civil Justice Reform), to minimize litigation, eliminate ambiguity, and reduce burden.

I. Protection of Children

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

J. Indian Tribal Governments

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

K. Energy Effects

We have analyzed this proposed rule under Executive Order 13211 (Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use). We have determined that it is not a “significant energy action” under that order because it is not a “significant regulatory action” under Executive Order 12866 and is not likely to have a significant adverse effect on the supply, distribution, or use of energy.

L. Technical Standards

The National Technology Transfer and Advancement Act, codified as a note to 15 U.S.C. 272, directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through OMB, with an explanation of why using these standards would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (such as for specifications of materials, performance, design, or operation; test methods; sampling procedures; and related management systems practices) that are developed or adopted by voluntary consensus standards bodies.

M. Environment

We have analyzed this proposed rule under Department of Homeland Security Management Directive 023-01, Rev. 1, associated implementing instructions, and Environmental Planning COMDTINST 5090.1 (series), which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (42 U.S.C. 4321-4370f), and have made a preliminary determination that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. A preliminary Record of Environmental Consideration supporting this determination is available in the docket. For instructions on locating the docket, see the ADDRESSES section of this preamble. This proposed rule would be categorically excluded under paragraphs L54, L57 and L58 of Appendix A, Table 1 of DHS Instruction Manual 023-01, Rev. 1. Paragraph L54 pertains to regulations which are editorial and procedural; paragraph L57 pertains to regulations concerning manning, documentation, admeasurement, inspection, and equipping of vessels; and paragraph L58 pertains to regulations concerning equipment approval and carriage requirements.

This proposed action involves amending rules relating to standards for marine engineering details for various types of vessels, including incorporation of national and international safety standards by reference. This proposed rule is part of the Coast Guard's ongoing regulatory reform efforts to increase compliance options for the regulated public while providing cost savings to the public and U.S. Government, and also would promote the Coast Guard's marine safety mission. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule.
