II. Executive Summary

Subchapter J of title 46 of the Code of Federal Regulations (CFR) contains the electrical engineering regulations and standards applicable to vessels and required shipboard systems regulated under subchapters D, H, I, I-A, K, L, O, Q, R, T, U, and W of title 46. A key component of subchapter J is the standards that are incorporated by reference (IBR) in 46 CFR 110.10-1 and cross-referenced throughout parts 110, 111, 112, and 113. On April 22, 2021, the Coast Guard published a notice of proposed rulemaking (NPRM) that contains a detailed description of the background and proposed changes. (86 FR 21440).

This final rule updates prior incorporations by reference in 46 CFR 110.10-1 and all of the sections in subchapter J that reference the updated IBR standards, adds a limited number of alternative standards, and eliminates outdated or unnecessarily prescriptive regulations in subchapter J. More specifically, this rule incorporates more recent editions of many standards, incorporates by reference additional standards for certain topics, and removes IBR standards that are no longer actively used by industry. Due to technological advances, it is necessary to update the current standards to ensure modern technologies are addressed in the regulations. In addition to updating the IBR standards, this rule implements the following four changes to subchapter J.

First, this rule eliminates the prescriptive requirements in 46 CFR 111.12-1(b) and (c) for generator prime movers. In accordance with 46 CFR 58.01-5, these generator prime movers continue to be required to meet standards of the American Bureau of Shipping (ABS) Steel Vessel Rules.

Second, this rule simplifies the electrical cable construction requirements in subpart 111.60 so they are similar to the classification society requirements currently accepted without supplement under the Coast Guard's Alternate Compliance Program (ACP).

Third, for classifications of hazardous locations in subpart 111.105, this rule adds the International Electrotechnical Commission's (IEC) 60092-502 as an alternative classification. This is an internationally accepted standard, and we are not aware of any notable casualty history attributed to its use as compared to vessels complying with the current applicable U.S. regulations for classification of hazardous locations.

Fourth, this rule amends 46 CFR subpart 112.05 to allow the use of an emergency generator in port. This optional capability to use emergency generators in port is acceptable if a set of additional safeguards, approved by the International Maritime Organization (IMO) in 2005, are provided to ensure the availability of emergency power.

The following table provides an overview of the types of changes and the affected sections.

III. Basis, Purpose, and Regulatory History

The legal basis of this rule is section 1333(d) of Title 43, United States Code (U.S.C.), sections 3306 and 3703 of Title 46 U.S.C., and Department of Homeland Security (DHS) Delegation No. 00170.1, Revision No. 01.2. The provisions of 43 U.S.C. 1333(d) grant the Secretary of the Department in which the Coast Guard is operating the authority to promulgate and enforce regulations with respect to lights and other warning devices, safety equipment, and other matters relating to the promotion of safety of life and property on artificial islands, installations, and other devices. The provisions of 46 U.S.C. 3306(a)(1) authorize the Secretary to prescribe regulations for the design, construction, alteration, repair, and operation of vessels subject to inspection, including equipment, appliances, propulsion machinery, auxiliary machinery, boilers, unfired pressure vessels, piping, and electric installations. Additionally, 46 U.S.C. 3703 grants the Secretary authority to provide for navigation and vessel safety and protect against hazards to life, property, and the marine environment by regulating vessel construction, alteration, repair, maintenance, operation, and equipping. DHS Delegation No. 00170.1, Revision No. 01.2, paragraph (II)(92)(b), delegates these authorities to the Coast Guard.

The purpose of this rule is to update the standards incorporated by reference in 46 CFR subchapter J, which provide detailed specifications for electrical equipment used by vessels. Newly published editions of the international standards referenced in subchapter J address new technologies and changes in best practices. The Office of Management and Budget's (OMB) Circular A-119 states agencies should undertake a review of the standards incorporated by reference every 3 to 5 years to remain current with technological changes. OMB encourages reducing reliance on unique government standards when an existing voluntary consensus standard would suffice. This rule follows the Circular by incorporating newer editions of industry standards and reducing the reliance on unique Coast Guard standards where industry standards are sufficient.

On April 22, 2021, the Coast Guard published a NPRM titled “Update to Electrical Engineering Regulations” (86 FR 21440) requesting comments on the proposed changes implemented by this final rule, including several updates to the standards incorporated by reference. A detailed description of the background and proposed changes are available in that NPRM. See 86 FR at 21442-60.

IV. Discussion of Comments and Changes

During the comment period for the April 22, 2021 NPRM (86 FR 21440), which ended on July 21, 2021, we received 15 comments. Several commenters expressed their support for the Coast Guard updating the standards incorporated by reference to newer editions and some confirmed they use them in current practice. The comments also offered us feedback on specific changes to the electrical engineering requirements and standards we proposed to incorporate by reference. The comments can be viewed in the docket following the instructions in the ADDRESSES section of this preamble. We summarize the comments and our responses, starting with general comments and then responding in order of relevant CFR section. Within each CFR section, we describe any changes to the final rule regulatory text from what was proposed in the NPRM.

General

A commenter submitted an editorial comment on the list of abbreviations in Section II for “MOU.” In this final rule, MOU is now correctly defined as Mobile Offshore Unit.

A commenter requested we update 33 CFR subchapter N to clarify the application of this rulemaking to Outer Continental Shelf (OCS) facilities and stated that, at a minimum, the Coast Guard should update 33 CFR 143.120 to establish the date on which the proposed rule would apply to a new floating OCS facility. Where subchapter N requires compliance with subchapter J, the date of applicability for vessels and facilities will begin 30 days after publication of this final rule, in accordance with the revised § 110.01-1(b). The updated requirements and standards in subchapter J apply to electrical installations contracted for after the effective date of the final rule.

The commenter also noted that the Bureau of Safety and Environmental Enforcement (BSEE) in the Department of the Interior is working on a regulatory update to incorporate more modern industry standards and recommended the Coast Guard engage with BSEE to ensure that both regulatory efforts are aligned, as the agencies propose to incorporate different revisions of the same industry standard in at least two cases. The Coast Guard and BSEE have a shared mission of ensuring safety on the OCS. We work closely together to ensure our requirements are not in conflict with each other, even if we use different revisions of the same standard. Because this final rule is not adding any new requirements for vessel owners and operators, it will not cause any conflicts with BSEE requirements. Any specific concerns can be addressed to either the Coast Guard's Eighth District Outer Continental Shelf Division staff (website: https://www.atlanticarea.uscg.mil/​D8/​OCS/​) or the Coast Guard's Outer Continental Shelf National Center of Expertise (OCSNCOE) (website: https://www.dco.uscg.mil/​OCSNCOE/​).

Two commenters requested that we clarify the applicability of subchapter J to Floating Production Units (FPUs), as the Coast Guard Office of Design and Engineering Standards' (CG-ENG) relevant policy letter, CG-ENG Policy Letter 01-13,^[1] only applies to classed FPUs rather than all FPUs in service. Similarly, a commenter requested that the Coast Guard clarify the applicability of subchapter J to floating OCS facilities, as the application of the subchapter has led to many requests for equivalencies and alternatives for a class of installations that may not technically be vessels. The comment stated that the Coast Guard should act on the National Offshore Safety Advisory Committee's recommendation that the Coast Guard issue a task statement to evaluate the suitability of subchapters F and J for floating OCS facilities. These requests are outside the scope of this rulemaking, which focuses on updating the electrical engineering standards set out in subchapter J but not further amending the applicability of subchapter J. Nevertheless, we have shared them with the appropriate Coast Guard offices. We encourage questions regarding the applicable regulations for floating OCS facilities to be sent to either the Coast Guard's Eighth District Outer Continental Shelf Division Staff (website: https://www.atlanticarea.uscg.mil/​D8/​OCS/​) or OCSNCOE (website: https://www.dco.uscg.mil/​OCSNCOE/​).

Subpart 110.01—Applicability

§ 110.01-1 General

We received requests for information on the implementation dates for the revised regulations. In response and to provide greater clarity for the public, this final rule includes an amendment to § 110.01-1(b) that explains the effective date of the requirements in this rule. The requirements implemented in this final rule will be effective 30 days after the publication of this final rule. Paragraph (b) will also clarify that subchapter J applies only to electrical installations contracted for after the effective date of this final rule. Existing paragraph (c) of this section will continue to allow a vessel's electrical installations to meet the subchapter J regulations in place when those systems were initially installed. According to existing 46 CFR 110.01-3(a), repairs and replacements in kind must comply with either the regulations in this subchapter or those in effect when the vessel was built. Per § 110.01-3(b), alterations and modifications, such as re-engining, re-powering, upgrading of the main propulsion control system, or replacing extensive amounts of cabling, must comply with the regulations in this subchapter, including updates implemented by this final rule. Per existing § 110.01-1(c), all electrical systems installed or under Coast Guard review prior to this date may meet the regulations in place at the time of installation or submittal to the Coast Guard.

Subpart 110.10—Reference Specifications, Standards, and Codes

§ 110.10-1 Incorporation by Reference

We received the following comments in regard to our update of the technical standards incorporated by reference in subchapter J in § 110.10-1.

Several commenters suggested incorporating by reference newer editions than we had proposed to incorporate in § 110.10-1. Because of the frequent release of new editions, and the time necessary to evaluate them and propose their incorporation, it is often impractical to incorporate standards or new editions that publish after we issue our NPRM. Instead, the Coast Guard considered whether the standards proposed in the NPRM are still sufficient and relevant to electrical engineering practices at the time of this final rule, even if a newer edition is available. We determined that the editions proposed in the NPRM are still sufficient and relevant.

Several commenters requested incorporating by reference different standards than are referenced in § 110.10-1 or proposed in the NPRM. The suggestions included standards and codes for alternative propulsion fuels; inspection, maintenance, and repair of equipment in hazardous locations; and hazardous location equipment directories or dossiers. These topics are not currently addressed in subchapter J. Including them at this stage would impose new regulatory requirements on vessels and facilities. This rule is intended to update the existing regulations in subchapter J and result in quantitative and qualitative savings for vessel owners. For this reason, standards for topics not currently addressed in subchapter J are outside the scope of this final rule. We may consider some of these standards in the future for incorporation by reference following a thorough technical analysis of the standards as well as their potential costs and benefits. Further, proposals for new requirements on topics not already included in subchapter J would be given additional public notice and opportunity for comment.

Additionally, we received specific comments on the following standards we proposed for incorporation by reference.

American National Standards Institute (ANSI)/UL standards: A commenter requested that we refer to the UL standards as ANSI/UL standards. In many of the regulatory text sections we do refer to such standards as ANSI/UL standards, but we do not do so in the IBR section, § 110.10-1. In that IBR section, we are required to list the standard name exactly as it appears on the cover of the standard.

The commenter also noted that many ANSI/UL standards related to hazardous locations replaced similar ISA standards, and suggested the UL standards should be referenced throughout the CFR. We agree with listing the ANSI/UL standards in addition to where we proposed to include the ANSI/ISA standard because of their similarities in requirements and options. In the NPRM we proposed to incorporate ANSI/ISA 12.12.01 (2015). In this final rule we are also adding ANSI/ISA-RP12.06.01 (2003) because it superseded a previously incorporated standard we removed, ISA RP 12.6 (1995). These two are the only ANSI/ISA standards that will be incorporated by reference in subchapter J and both are active standards. Where the ANSI/ISA series of standards are referenced in §§ 111.105-3(b)(2), 111.106-3(b)(2), and 111.108-3(b)(2), this final rule adds the ANSI/UL series as an option in those sections as well.

IEEE 100 (2000): A commenter noted that the Institute of Electrical and Electronics Engineers (IEEE) withdrew the standard IEEE 100 (2000). IEEE 100 (2000) is only referenced in § 110.15-1 regarding electrical and electronic term definitions. We have decided to retain it in subchapter J because the definitions are still relevant. We have confirmed that the standard is still available for the public to purchase despite IEEE withdrawing it. We acknowledge that a revision to the standard is underway and we will consider updating references to this standard in the future.

IEEE 1580 (2010): A commenter suggested we incorporate the 2018 edition. The 2018 edition was still in the draft stage when we published the NPRM in April 2021, and we were not able to propose draft standards for incorporation by reference. The IEEE board approved the IEEE 1580 (2021) on November 9, 2021, and published it on March 23, 2022, both dates after the comment period for the NPRM closed. The IEEE 1580 (2021) standard superseded the 2010 version. IEEE 1580 provides recommended practice for marine cable use on shipboard and fixed or floating facilities, and the 2021 edition addresses changes in changes in technology and revisions to referenced standards since 2010. The Coast Guard has decided that the 2010 version is still sufficient and relevant for marine cables at the time of this final rule. However, the public can submit equivalency requests for the 2021 edition to the Marine Safety Center (MSC) in accordance with § 110.20-1.

IEC 60092-302:1997: A commenter noted that this standard was superseded by IEC 60092-303-2, Electrical installations in ships—Part 302-2: Low voltage switchgear and controlgear assemblies—Marine power, published in 2019. We have decided to retain the 1997 edition until we can thoroughly review the 2019 edition. However, we may consider switchgear meeting the standards in IEC 60092-302-2:2019 under the equivalency provisions of § 110.20-1.

ISA RP 12.6:1995: We proposed in the NPRM to remove ISA RP 12.6 because ISA has withdrawn it. A commenter noted that a new standard, ANSI/ISA RP12.06.01, has superseded ISA RP 12.6. The commenter is correct. Because the two standards are very similar, we are replacing the withdrawn ISA RP 12.6 standard with the new ANSI/ISA RP12.06.01 standard as suggested. This final rule incorporates by reference ANSI/ISA-RP12.06.01:2003 in § 111.105-11. ANSI/ISA-RP12.06.01 is a recommended practice that promotes the uniform installation of intrinsically safe systems in hazardous (classified) locations and clarifies the requirements of Articles 504 and 505 of National Fire Protection Association (NFPA) standard NFPA 70.

Subpart 110.25—Plan Submittal

§ 110.25-1 Plans and Information Required for New Construction

A commenter noted that the proposed changes to § 111.105-3 provided the option to select electrical equipment on any single vessel to comply with NFPA 70 Articles 500-504, or NFPA 70 Article 505, or IEC 60092-502, based on either the Division or the Zone method of hazardous location classification. The commenter suggested that we amend the plan requirements for hazardous locations in § 110.25-1 to ensure the classification method is indicated on the plans submitted for review. We agree with this suggestion and are incorporating it into this final rule. The extent and classification of all hazardous locations is already required in the existing § 110.25-1(i) but clearly indicating the method of classification, Division or Zone, is important to ensure appropriate selection of equipment for the hazardous location. In this final rule, we amend § 110.25-1(i) to require that the plans indicate the method of classification of the hazardous locations in addition to the other requirements already included in paragraph (i).

Subpart 111.10—Power Supply

§ 111.10-9 Ship's Service Supply Transformers; Two Required

A commenter noted that our proposed revision to the note to § 111.10-09 concerning ship's service transformers appears to contradict the text of § 111.10-09 regarding the number of transformers. We disagree. Section 111.10-3 requires that the shipboard power supply system on self-propelled vessels have at least two electric generating sources. The intent of § 111.10-09 is to continue this requirement by duplicating the number of transformers that are used to supply the ship's service distribution system. As explained in this note, the intent is not to provide duplication of ship's service distribution system circuits after the ship's service switchboard. This is a long-standing position that is explained in Coast Guard guidance, specifically page 16 of Navigation and Vessel Inspection Circular (NVIC) 2-89, “Guide for Electrical Installations on Merchant Vessels and Mobile Offshore Units,” dated August 14, 1989.^[2]

Subpart 111.12—Generator Construction and Circuits

§ 111.12-11 Generator Protection

Section 111.12-11(g) states that a ship's service generator and its switchboard must be in the same space and states that a control room inside the machinery casing is not considered outside the machinery space. Paragraphs 111.12-11(g)(1) and (2) provide two arrangements that the Coast Guard considers to meet this requirement. In other words, we consider a switchboard room within the machinery space, containing the overcurrent protection on the switchboard, to be satisfactory, regardless of whether there are centralized engineering controls or monitoring in that control room. This rule, which replaces a reference to a “semiconductor rectifier” with “semiconductor converter” in paragraph (g), does not substantively change these existing provisions. A commenter asked if a control room that is an air-conditioned switchboard room with generator controls on a switchboard, but without centralized engineering control and monitoring, is an acceptable control room. This question is beyond the scope of this rulemaking, but questions regarding compliance with Subchapter J may be submitted to the MSC.

Subpart 111.15—Storage Batteries and Battery Chargers: Construction and Installation

Two commenters suggested we consider incorporating by reference IEEE 1187-2013, “IEEE Recommended Practice for Installation Design and Installation of Valve-Regulated Lead Acid Batteries for Stationary Applications.” The commenters noted that although FPUs are not stationary, they are not ocean-going vessels either. The commenters also noted because FPUs do not have the range of motions of a vessel, they use valve-regulated lead acid batteries (as governed by IEEE 1187-2013) rather than the vented lead-acid batteries covered in the NPRM's updates to subchapter J. We understand the unique characteristics of FPUs may require additional options and guidance. Specifically, 33 CFR 143.120(b) and CG-ENG Policy Letter 01-13 allow alternate proposals for floating OCS facilities. System designers may submit applications to the MSC demonstrating that a system using valve-regulated lead acid batteries, as governed by IEEE 1187-2013, provides an equivalent level of safety in accordance with § 110.20-1. We understand this IBR suggestion and may consider it in a future rulemaking. Further, we find that we cannot include this suggestion in this final rule because, in order to add the standard and those additional requirements, we would prefer to conduct an additional analysis of alternatives and provide the public opportunity to review and comment on its addition.

Subpart 111.30—Switchboards

§ 111.30-5 Construction

In the NPRM, we proposed replacing the existing reference to section 8.3 of IEEE 45-2002 in § 111.30-5(a)(1) with a reference to section 6 of the more recent IEEE 45.7-2012. A commenter noted section 6.3.3 of IEEE 45.7 requires a steering gear breaker trip set to not less than 200 percent of locked rotor current. This conflicts with § 58.25-55(a)(2), which requires a trip set point between 175 and 200 percent of locked rotor current. We agree that the change we proposed in the NPRM would present an unintended conflict with other existing regulations. The intent of § 111.30-5 is to address switchboard construction, not overcurrent protection for specific systems, so when reviewing IEEE 45.7 we did not observe that the standard added a requirement for the steering gear circuit overcurrent protection. We did not intend the NPRM to propose a change to the existing requirements for steering gear circuit overcurrent protection. For this reason, in § 111.30-5(a)(1) of this final rule, we are incorporating section 6 of IEEE 45.7-2012, excluding section 6.3.3.

A commenter asked for clarification of the proposed § 111.30-5(c) regarding switchboard construction, which stated that “[t]he interchangeability and compatibility of components complying with both IEEE and IEC cannot be assumed.” We agree this proposed paragraph (c) could have caused confusion. Our intent in this paragraph was to discourage the mixing of acceptable standards in a manner that could result in a potentially unsafe switchboard. We recognize that complying with and enforcing this relatively vague requirement would be difficult, and we have accordingly deleted it in this final rule. Switchboards should be constructed in accordance with the standards incorporated by reference in subpart 111.30.

§ 111.30-19 Buses and Wiring

In the NPRM, we proposed replacing the existing reference to section 7.10 of IEEE 45-1998 in § 111.30-19(a)(1) with a reference to section 5.10 of the more recent IEEE 45.7-2012. A commenter noted section 5.10 of IEEE 45.7-2012 appears to have less strict requirements for generator bus sizing and could be interpreted to not require sizing to support overload operation of the generator for a sustained period. We disagree. The requirements are very similar, and IEEE 45.7-2012 reflects the latest guidance on bus sizing.

§ 111.30-25 Alternating-Current Ship's Service Switchboards

A commenter suggested that the generator field rheostat (manual voltage controller) currently required by § 111.30-25(c)(1) was of limited value and is not required by other regulatory bodies. We understand this suggestion and may consider it in a future rulemaking. In order to remove the requirement, we would prefer to conduct an additional analysis of alternatives and provide the public opportunity to review and comment on its removal. In the meantime, however, system designers may submit switchboards with alternative instrumentation that provides an equivalent level of safety to the MSC in accordance with § 110.20-1.

Subpart 111.33—Power Semiconductor Converter Systems

In the NPRM, we proposed changing the heading of subpart 111.33 from Power Semiconductor Rectifier Systems to Power Semiconductor Converter Systems and changing references to rectifiers to converters. This proposed change aligned with general industry practice of using the term converter as it is more general than rectifier. This subpart applies to rectifiers (alternating current (AC) to direct current (DC)), inverters (DC to AC), and other power converters. Additionally, in the NPRM we proposed updating the standards incorporated by reference in this subpart to more recent editions. A commenter noted that 4.31.19.12 of IEEE 45.2-2011, which would replace 10.20.12 of IEEE 45-2002, covers rectifiers. The commenter is correct in this regard. However, 4.31.19.12 of IEEE 45.2-2011 provides the required nameplate data, and the Coast Guard determined the requirements of this section are also generally applicable to any power semiconductor converter system.

In addition, in the NPRM, we proposed replacing references throughout subpart J to “semiconductor rectifier (SCR)” with references to “semiconductor converter”. However, upon further review following the NPRM's publication, we realized that some instances of this amendment were inadvertently not included in the amendatory language for the NPRM. We have updated the amendatory language in this final rule to include these missed instances of “converter” in this final rule at §§ 111.33-1 and 111.33-3(b).

Subpart 111.40—Panelboards

§ 111.40-1 Panelboard Standard

A commenter noted Section 9.10 of IEEE 45.1, proposed for incorporation by reference in the NPRM, includes multiple sub-sections but only subsection 9.10.1 is directly applicable to panelboards. The commenter suggested updating the reference to only include this subsection. We agree, and in the interest of greater precision we revise § 111.40-1 in this rule to only reference subsection 9.10.1.

Subpart 111.50—Overcurrent Protection

§ 111.50-3 Protection of Conductors

A commenter noted that currently neither § 111.50-3 nor § 111.20-15 clearly addresses NFPA 70—National Electric Code (NEC) requirements for transformer secondary conductor protection and suggested that § 111.50-3 should include or cite to NEC 240.21(C)(1) requirements. NEC 240.21(C)(1) explicitly states that primary overcurrent protection is insufficient to protect secondary conductors of delta-wye transformers. In the NPRM, we did not propose substantive changes to these two sections beyond incorporating the more recent editions of the standards. Adding the requirements at NEC 240.21(C)(1) to § 111.50-3 would require additional analysis and opportunity for the public to review and comment. Nevertheless, we may consider incorporating NEC Article 240, which provides guidance for transformer conductor overcurrent protection, in § 111.50-3 in the future.

A commenter also said that neither § 111.50-3 nor § 58.25 currently address DC steering gear motors. The commenter also said that both §§ 111.50-3 and 58.25 are silent on the use of fuses for overcurrent protection in these systems. The commenter suggested that we remove the cross-reference to 46 CFR 58.25 and revise § 111.50-3 to align with ABS SVR 4-8-2/9.17.5 standards on DC steering gear motors and prohibiting fuses. We disagree with the suggested change. Paragraph 58.25-55(a)(1) specifically requires DC steering gear motors to be protected from overcurrent by a circuit breaker at the switchboard. This section does not list fuses as an acceptable means of overcurrent protection. Vessel owners and operators must ensure DC steering gear motors are protected from overcurrent by circuit breakers unless an equivalent arrangement is approved by the MSC in accordance with § 110.20-1. We did not propose substantive changes to these two sections in the NPRM beyond incorporating the more recent editions of the standards already incorporated by reference in § 111.50-3. However, we will consider updating our steering gear motor regulations in the future following a review of the latest advances in steering gear power and control systems.

Subpart 111.51—Coordination of Overcurrent Protection Devices

§§ 111.51-1 Purpose and 111.51-5 Protection of Vital Equipment

In the NPRM, we proposed to revise § 111.51-1 to set out a broad introductory discussion of the requirements for coordination of overcurrent protection devices that is based on the recommendations in IEC 60092-202:2016 and not substantively different from the existing § 111.51-1 that it replaced. A commenter noted the term “continuity of service” as used in the proposed revisions to § 111.51-1, as well as in the current text of § 111.51-1, is not defined and could be interpreted in a number of ways. Additionally, the same commenter also recommended editing § 111.51-5(b)(2) to allow for cases where multiple protective devices are directly in series due to the arrangement of the power system and vendor equipment supply or requirements for disconnecting device. Alternatively, they suggested we define that a protective device refers to a set of one or more protective devices which protect the same segment of the electrical system. The commenter was concerned the section could be interpreted to require explicit coordination between protective devices within the same feeder or branch circuit.

It is not the intent of this final rule to substantively alter our existing regulations for coordination of overcurrent protection devices. Continuity of service is defined in IEC 60092-202:2016 as a “condition where, after a fault in a circuit has been cleared, the supply to the healthy circuits is re-established.” More importantly, the goal of overcurrent protection coordination is to minimize the impact of short circuits on vital equipment as explained in §§ 111.51-1 and 111.51-5. If multiple protective devices are in series, it is incumbent on the system designer to demonstrate the devices satisfy the intent of overcurrent protection coordination. Additionally, proposing a unique definition for protective devices is not a preferred option where the definition is widely used and defined by a standard. We encourage the use of established industry standards and definitions. If there are any vessel or system specific arrangements being proposed for Coast Guard certificated vessels, their equivalency with this subpart can be demonstrated to the MSC in accordance with § 110.20-1. We made no changes from the proposed rule in § 111.51-5.

Subpart 111.60—Wiring Materials and Methods

§ 111.60-3 Cable Application (Existing)

In the NPRM, we proposed to delete this section because it is unnecessarily prescriptive. In its place, we proposed that regulated entities would consult the current and proposed cable construction standards in proposed new § 111.60-1 for the application of specific types of cable. A commenter expressed concern that cable for specialized applications, such as scientific research instruments and passenger ferry Wi-Fi networks, is sometimes not available or cost-prohibitive to meet the fire test requirements. The commenter recommended retaining § 111.60-3 largely as written. Based on our research for available products, the Coast Guard has determined that common types of cables that comply with the standards in § 111.60-1 are available and provide the safest option for U.S. vessels. Additionally, our research indicates the cost will be comparable to all other cable suitable for marine applications. Accordingly, this final rule retains the amendment from the NPRM to remove § 111.60-3. We will consider other cable on a case-by-case basis in accordance with the equivalency provisions of § 110.20-1.

§ 111.60-4 Minimum Cable Conductor Size

A commenter noted we did not propose changing the required minimum conductor size in this section of 0.82 square millimeters (mm² ) and 2.1 mm² for control and power cable, respectively. The commenter explained that vessels inspected under the ACP have a lesser conductor size requirement. For example, ABS MVR 4-8-2/7.7.2 allows smaller minimum conductor sizes of 0.5 mm² and 1.5 mm² for control and power cable respectively. (The metric dimensions given in this section are metric conversions of the standard American Wire Gauge sizes rather than standard metric wire sizes suggested by this commenter and used in the ABS rule.) The commenter recommended we decrease the metric size requirements to match the requirements applicable to ACP vessels because they believed doing so would eliminate the need to excessively oversize metric cable to meet rules that are currently written to align with common AWG sizes. Vessels enrolled in the ACP comply with a comprehensive set of engineering standards and an inspection regime that collectively provide a level of safety equivalent to complying solely with the regulations in 46 CFR even though the requirements are not identical. As the commenter noted, we did not propose substantive changes to this section in the NPRM and do not intend to change it in the final rule. Allowing smaller minimum conductor sizes on all vessels regulated by subchapter J is a less stringent requirement that we may consider in the future following additional analysis and opportunity for public comment. Presently, the metric conductor size requirements in this section are still considered reasonable and safe, and we made no additional changes based on this recommendation.

§ 111.60-6 Fiber Optic Cable (Existing)

In the NPRM, we proposed to remove current § 111.60-6 because fiber optic cable that complies with § 111.60-1 is now available. A commenter contended that such fiber optic cable is not readily available. We agree that it may be difficult to find fiber optic cable to meet the standards in § 111.60-1 and have decided to forgo the proposed change to remove §§ 111.60-2 and 111.60-6. This final rule does not remove existing §§ 111.60-2 and 111.60-6, or the cross references to §§ 111.60-2 and 111.60-6 within the applicable list of standards incorporated by reference in §§ 110.10-1(j)(14), 110.10-1(q)(23), 110.10-1(k)(34), 110.10-1(k)(35), and 110.10-1(j)(13), where they were already included. However, in this final rule we have updated the standards mentioned within §§ 111.60-2 and 111.60-6 to conform with updates to standards incorporated by reference within this subchapter.

§ 111.60-11 Wire

A commenter noted the reference to Section 5.7 of IEEE 45.8-2016 in § 111.60-11 and pointed out that this section does not address wire. We agree and have removed the reference to Section 5.7 of IEEE 45.8 from this section because it is not related to the topic of § 111.60-11. The commenter also suggested that wire constructed to a recognized commercial standard or military specification MIL-W-16878 or MIL-W-22759, with particular attention to the effects of vibration, moisture, ambient temperature, and other adverse conditions such as contaminants and oils that may be present should be acceptable. We agree in principle. Section 111.60-11(c) provides that wire must the requirements set out in one of three standards for wire and concludes with “or equivalent standard.” System designers choosing an alternative standard they believe equivalent, such as that described by the commenter, should discuss it with the MSC. There are too many relevant standards to incorporate them all. Instead, we have decided to offer three standards as guidance for acceptable wire requirements. We will consider equivalency requests in addition to the standards we incorporate by reference.

Subpart 111.70—Motor Circuits, Controllers, and Protection

§ 111.70-3 Motor Controllers and Motor-Control Centers

A commenter noted that the proposed regulatory text in the NPRM implied that we were making changes to §§ 111.70-3(c)(2) and (d)(1)(v) but the proposed regulatory text as presented in the NPRM was unchanged from existing regulatory text. This observation is correct. We erroneously included these sections in the NPRM's amendatory instructions, but we did not actually propose any changes. No changes were intended. This final rule does not include any amendments to the regulatory text at §§ 111.70-3(c)(2) and (d)(1)(v).

Subpart 111.75—Lighting Circuits and Protection

§ 111.75-17 Navigation Lights

In the NPRM, we proposed incorporating EN 14744 in § 111.75-17 as an additional alternative standard for navigation lights. Currently, UL 1104 is the only standard incorporated by reference in § 111.75-17. One commenter suggested that, since UL 1104 is no longer supported by UL and does not address electromagnetic interference or light-emitting diode (LED) light lifecycle degradation, it should be removed from this section and EN 14744 should be adopted as the sole standard for all navigation lights, including AC- and DC-powered lights, incandescent and non-incandescent lights, lights on all vessel types and sizes, and lights on inspected and non-inspected vessels.

We disagree with the suggestion to remove UL 1104. Several years ago, UL transferred responsibility for the maintenance of UL 1104 to the American Boat and Yacht Council (ABYC). Prior to this rulemaking, UL 1104 was the only standard for the construction and testing of navigation lights incorporated by reference in subchapter J, and it is currently being used by several navigation light manufacturers. Lights manufactured and certified to UL 1104 meet the current luminous intensity and colorimetric requirements of the International Regulations for Preventing Collisions at Sea, 1972 (1972 COLREGS). Additionally, the environmental performance requirements contained in UL 1104 are similar in intent to those in EN 14744. For these reasons, we are not removing UL 1104 at this time.

Additionally, we cannot incorporate by reference EN 14744 for all light and vessel types as suggested. The scope of this rule is limited to subchapter J. The navigation light requirements in subchapter J generally apply to larger, inspected commercial vessels. The requirements for navigation lights on certain smaller, inspected commercial vessels, uninspected commercial vessels, and recreational vessels are contained in other subparts of the CFR. We did not propose amendments to those subparts in the NPRM, and because of this we cannot incorporate by reference EN 14744 for all light and vessel types.

Since UL transferred UL 1104 to ABYC we have worked with ABYC and other navigation light stakeholders to develop an updated navigation light standard to replace UL 1104. This standard, ABYC C-5, Construction and Testing of Electric Navigation Lights, published in July 2021, too late for inclusion in the NPRM and after the NPRM comment period closed. ABYC C-5 is applicable to all light and vessel types and addresses both electromagnetic interference and LED light lifecycle degradation. We may address the incorporation by reference of ABYC C-5, a broader incorporation by reference of EN 14744, other potential navigation light standards, and navigation light requirements for all vessel types in a future, broader, Coast Guard proposal.

Subpart 111.83—Shore Connection Boxes

§ 111.83-7 High Voltage Shore Connection

A commenter noted that proposed new § 111.83-7 only applies the requirements of IEC/IEEE 80005-1:2019 to vessels required by law to have high voltage shore connections (HVSCs), and recommended removing that limitation. The Coast Guard agrees the proposed limitation to only vessels that were required by state or local law to connect to HVSC would have created unnecessary confusion. This section does not require compliance with IEC/IEEE 80005-1:2019; it is a recommendation for best practices and additional safety. For vessels that connect to electrical shore power using an HVSC, we recommend complying with IEC/IEEE 80005-1:2019 regardless of whether it is required by a state or local jurisdiction. For this reason, we have removed the limitation that § 111.83-7 would only apply to vessels required by law to have shore power and instead provide this section as a recommended standard for all vessels that use an HVSC.

Another commenter requested that the ABS Guide for High Voltage Shore Connection be considered for incorporation by reference as an alternative standard for HVSCs. We have not incorporated this guide. IEC/IEEE 80005-1:2019, which is incorporated by reference in the new § 111.83-7, is an international voluntary consensus standard that provides an acceptable baseline recommendation, while the ABS Guide for High Voltage Shore Connection is a classification society guide. Although the ABS Guide for High Voltage Shore Connection may be a satisfactory alternative for consideration in an equivalency request, it is not necessary to list a classification society guide in the regulations when an international voluntary consensus standard is available. The National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) directs Federal agencies to use voluntary consensus standards in their regulatory activities unless doing so would be inconsistent with applicable law or otherwise impractical.

Subpart 111.99—Fire Door Holding and Release Systems

§ 111.99-5 General

The NPRM proposed updating the existing citation in § 111.99-5 to reflect a more current edition of the International Convention for Safety of Life at Sea, 1974 (SOLAS), Sixth edition. A commenter noted that SOLAS II-2/9.4.1.1.5 includes a number of paragraphs that include requirements for safe functioning of the fire door release system. The commenter suggested that we expand § 111.99-5 to include these additional paragraphs in II-2/9.4.1.1.5 beyond that which was referenced in the NPRM. We understand that SOLAS contains additional requirements for fire doors. Vessels that comply with SOLAS must meet these requirements, but requiring all vessels that must comply with Subchapter J's requirements meet these standards would place regulatory requirements on these vessels without providing appropriate opportunity for public notice and comment. Accordingly, we did not incorporate this suggestion at this time.

Subpart 111.105—Hazardous Locations

One commenter suggested we remove the Division system for classification of hazardous locations from subchapter J. The commenter said that compliance would be simpler if only the Zone system was accepted. We disagree. This is an established system used extensively in North America and removing the Division system would adversely affect many equipment manufacturers.

Another commenter requested we incorporate by reference American Petroleum Institute (API) standards API RP 14FZ and API RP 500, and IEEE 1187-2013. As we discussed in regard to a comment on subpart 111.15, we are not inclined to incorporate IEEE 1187 because it contains additional requirements beyond what we believe necessary to incorporate at this time. API RP 14FZ and API RP 500 are already incorporated or will be incorporated in a very limited scope, which we have determined to be a reasonable level at which to require these standards.

§ 111.105-3 General Requirements and System Integrity

The intent of § 111.105-3 is to ensure all electrical equipment installed in a hazardous location is appropriate for the location. One commenter suggested that acceptable electrical components may be combined in a manner that may produce an assembly that can ignite a hazardous atmosphere and that this may not be caught in after-installation inspections. The commenter suggested several standards to address this concern, such as ANSI/UL 698A, IEC TS 60079-46, ANSI/UL 508A, and UL 2011. Additionally, the commenter suggested that this rule address the importance of assembly verification throughout the equipment lifecycle from design to installation. Assembly verification throughout the process is an important issue for system designers, but it is outside the scope of this rulemaking. Applicants must include assemblies of electrical equipment in plans and installation details in their request for Coast Guard review in accordance with §§ 110.25-1(i) and (j). The Coast Guard then reviews the plans and installation details to ensure safe assembly in accordance with these standards.

Several commenters requested clarification of the phrase “and not in combination in a manner that will compromise system integrity or safety,” proposed in the NPRM for new § 111.105-3(c). Additionally, commenters suggested that we reorganize § 111.105-3 to better separate equipment selection standards and installation requirements. Since its initial adoption in 1996, our intentions in § 111.105-5 (which we had proposed to move into § 111.105-3) have been to ensure that proper and safe equipment is used in hazardous locations and to allow safe combinations of equipment complying with either NFPA 70 (Division system) or the IEC 60079 series of standards (Zone system).^[3] The phrase in question, located in § 111.105-3(c) in this final rule, ensures such systems are carefully designed because the methods of classification of hazardous locations can differ. When a location is subject to two classification systems, it may have two different classifications. For example, a specific cargo oil tank may be classified as a Class I, Division 1, location under one system and Zone 0 under the other. In this example, electrical equipment approved for Class I, Division 1 (intrinsically safe) or approved for Zone 0 (ia) may be installed in the cargo tank.

In the NPRM we proposed to combine §§ 111.105-3 and 111.105-5 into § 111.105-3 to be consistent with §§ 111.106-3 and 111.108-3. This created confusion among commenters, and we have decided to revise our approach to proposed § 111.105-3. Instead, we have renumbered the proposed § 111.105-7 as § 111.105-3 and amended it to be more consistent with §§ 111.106-3 and 111.108-3 by adding notes after new paragraphs 111.105-3(b)(1) and (b)(2). This change better clarifies the appropriate guidance for using Zone equipment in Division-designated spaces or using Division equipment in Zone-designated spaces. Additionally, as mentioned earlier, we will also require in § 110.25-1(i) that applicants clearly indicate the hazardous location method of classification, Division or Zone, in their plan submissions.

One comment suggested that it was more appropriate to incorporate by reference Clause 7 rather than Clause 6 of IEC 60092-502 in § 111.105-3(b). We disagree. Clause 6 concerns the requirements of electrical equipment in hazardous areas while Clause 7 addresses installation of electrical equipment in hazardous areas. The intent of § 111.105-3(b) is to prescribe the standards for electrical equipment intended for hazardous areas (locations), not specifically installation. This is the same as § 111.108(a)(3). It was not our goal for the proposed modifications to § 111.105 to substantively change the standards fundamental to equipment selection. In the existing regulations, in accordance with § 111.108-1(b), all vessels could use the standards specified in 46 CFR Subpart § 111.108. Revisions to § 111.105 are intended to make this clearer.

One comment noted that for electrical installations on mobile and fixed offshore units the proposed requirements only reference Clause 8 of IEC 61892-7. The commenter also noted that Clause 8 excludes guidance on cables and conduits and Clause 9 of IEC 61892-7 is for cables and wiring systems. This is correct. We intentionally did not reference Clause 9 for cables and wiring systems. Prior to this rulemaking, we previously incorporated Clause 6 of IEC 61892-7:2007. Clause 6 addresses electrical equipment in hazardous areas, but not wiring or cable systems. We proposed to incorporate by reference the more recent Clause 8 of IEC 61892-7:2019. Clause 8 similarly addresses electric equipment by referencing Clause 5 of IEC 60079-14:2013. It was not our intent to add wiring and cabling system requirements to § 111.105-3. The requirements for wiring and cable systems in hazardous locations are in § 111.105-17.

One commenter noted that both Clauses 8 and 9 of IEC 61892-7 reference IEC 60079-14, Electrical installations design, selection, and erection, and suggested that we should incorporate IEC 60079-14 by reference. We disagree with the suggestion. Since we incorporated by reference IEC 61892-7:2007 in 46 CFR subchapter J, the standard has evolved and been updated twice. In 2014, the IEC 61892-7 requirements for installations in hazardous area were rewritten based on the requirements of IEC 60079-14:2013. In the latest edition, 2019, IEC 61892-7 was completely rewritten and references are, to the extent possible, made to IEC 60079-14:2013 and to other relevant standards. At this time our intent is to only apply IEC 60092-14:2013 as it is referenced in Clause 8 of IEC 618792-7:2019. We describe Clause 8 in the previous paragraph. Despite the commenter mentioning Clause 9 of IEC 61892-7:2019, we did not propose to incorporate it in the NPRM. We already address the cable and wiring requirements using standards we deem sufficient in § 111.105-17. It is commonplace for standards to reference other standards, but incorporating every standard simply because it is cross-referenced would cause us to incorporate more standards than are reasonably necessary to convey the relevant requirements. A broader incorporation by reference of IEC 61892-7:2019 would require additional regulatory analysis and an additional opportunity for the public to review and comment.

§ 111.105-28 Internal Combustion Engines

A commenter said that § 111.105-28 states “Internal combustion engines installed in Class I Divisions 1 and 2 (Zones 1 and 2),” but there is no direct equivalency between Class I Division 1 and Zone 1 as Class I Division 1 covers equipment in Zone 0 as well. The commenter suggested that references to Class I Divisions (1 and 2) and Zones be removed from the section. We disagree with this suggestion. Currently, § 111.108-1(b) allows U.S. Mobile Offshore Drilling Units (MODUs), floating OCS facilities, and vessels other than Offshore Supply Vessels (OSVs) regulated under 46 CFR subchapter L and U.S. tank vessels that carry flammable and combustible cargoes, to comply with ASTM F2876 per § 111.108-3(g). Our purpose in changing § 111.105 is to improve the consistency of the regulations related to hazardous areas in §§ 111.105, 111.106, and 111.108. It does not change the requirements. Although we agree with the commenter's assertion that Class I Division I may also cover equipment in IEC Zone 0, internal combustion engine installations are generally prohibited for use in shipboard IEC Zone 0 areas.

A commenter noted that engines may be certified by the manufacturer to ASTM F2876 and its maximum surface temperature requirements. The commenter also noted that ASTM F2876 does not address different testing requirements from Zone 1 and Zone 2 applications. The primary purpose of ASTM F2876 is determining the maximum operating temperature of the engine, in order to ascertain the suitability of the engine installation in hazardous areas associated with the autoignition temperature of various flammable cargoes. An independent laboratory must certify all electrical equipment associated with the engine installation. Although ASTM F2876 contains other requirements in addition to temperature measurement, the references to EN 1834-1 within ASTM F2876 are recommendations only.

§ 111.105-50 Alternative Standard to the Classification of Hazardous Locations Requirements of This Subchapter

A commenter noted we proposed in the NPRM to incorporate IEC 60092-502 without also incorporating the Coast Guard's interpretations and additional requirements, issued in April 2009, which we maintain on the Coast Guard's website for the ACP.^[4] The commenter did not offer an opinion or recommendation on this proposal, but asked us to clarify if these requirements in the IEC 60092-502 Supplement would be obsolete when we incorporate IEC 60092-502:1999. The intent of these interpretations and supplemental requirements was for vessels in the ACP to achieve equivalency with the regulations in 46 CFR. The Coast Guard has determined that IEC 60092-502, even without these interpretations and supplemental requirements, is a satisfactory alternative method for the classification of hazardous locations. When using IEC 60092-502 to classify hazardous locations, vessels no longer need to comply with our IEC 60092-502 Supplement issued in April 2009.

A commenter said that our proposed incorporation by reference of IEC 60092-502:1999 as an alternative method for classification of hazardous location, while also referencing §§ 32.60-20(c) and 38.20-10, resulted in conflicting ventilation requirements. We agree that they can be conflicting. Unfortunately, existing U.S. and international requirements for cargo pump room ventilation are different. Sections 32.60-20(c) and 38.20-10 both require an air change every 3 minutes (20 air changes per hour) while Clause 8.1.3 of IEC 60092-502:1999 requires an air change every 2 minutes (30 air changes per hour). We intend for IEC 60092-502:1999 to be an alternative to existing regulations. At this time we are not changing 46 CFR subchapter D, including §§ 32.60-20(c) and 38.20-10, nor modifying IEC 60092-502. System designers choosing to use IEC 60092-502:1999 for classification of hazardous locations must follow the standard. However, we are revising § 111.105-50(c) from what was proposed in the NPRM to clearly state when 30 air changes per hour are required. Specifically, if IEC 60092-502:1999 is used, cargo handling rooms and other spaces where hazardous location classification is dependent upon ventilation must have mechanical ventilation capable of at least 30 air changes per hour, based upon the gross volume of the space.

Subpart 112.05—General

§ 112.05-5 Emergency Power Source

Section 112.05-5(a) requires that an emergency power source have the capacity to simultaneously supply all loads connected to it. To further clarify this, in the NPRM we suggested adding the phrase “at a unity (1.0) service factor.” This simply means the emergency power source must be sufficiently sized to operate all loads at their full rated capacity.

A commenter requested we modify the required capacity of the emergency power source with a phrase such as “with due regard being paid to such services as may have to be operated simultaneously.” They stated that their proposed change would allow use of emergency generators that are more closely sized to the loads that would be needed in an emergency. We disagree with the commenter's proposed change. It would change the intent of the existing regulation by allowing more discretion and ambiguity than a specific load capacity measurement. In the interest of providing a clear discernable standard that we considered safe, we will proceed with requiring the unity 1.0 service factor as proposed in the NPRM.

In table 1 to § 112.05-5 footnote 2, we are replacing the reference to § 111.93 with a reference to § 58.25-65 because we moved the requirements in § 111.93 to § 58.25-65 in a previous rulemaking (60 FR 24776, May 10, 1995). Although we did not include this amendment in the NPRM, this is a conforming edit that will not have an impact on the existing emergency power requirements.

§ 112.05-7 Use of Emergency Generator in Port

A commenter noted that existing Coast Guard policy regarding in port use of the emergency generator requires that a qualitative failure analysis (QFA), design verification test procedure (DVTP), and a periodic safety test procedure (PSTP) be submitted for review, but the proposed § 112.05-7 did not have this requirement. This is correct. The requirements for these documents are contained in 46 CFR subchapter F Subpart 61.40. Based on this subpart, an emergency generator intended to meet § 112.05-7 for use in port would be required to submit a QFA, DVTP, and PSTP for review. We do not see the need to duplicate this requirement in § 112.05-7.

A commenter said we could require more comprehensive alarms in § 112.05-7(c) and requested that, at a minimum, we consider clarifying the alarms and shutdowns required versus the shutdowns allowed or disallowed. We understand the commenter's intent and request for more specific information, but this regulation provides the baseline requirements. We do not agree with revising the regulation to require additional alarm regulations at this time because we have determined that the baseline alarm requirements are still adequate.

A commenter noted that the proposed regulations regarding in-port use of the emergency generator at § 112.05-7(c) require the vessel be equipped with displays and alarms in the centralized control station and alarm monitoring at the engineers' quarters. The commenter pointed out that not all ships have a centralized control station or alarm summary panels in the crew's quarters. These regulations set the baseline requirements for in-port use of the emergency generator. If a system designer cannot meet the requirements due to unique ship characteristics, the designer may propose equivalent arrangements to the MSC in accordance with § 110.20-1. Our intent for these alarm location regulations is to require alarms both where the emergency generator is normally controlled and where crew would normally be located in port.

Additionally, two commenters noted that the NPRM did not discuss arrangements for feedback to power the vessel's main switchboard for habitability services and any special load analysis considerations or interlocks requirements for paralleling with main generators. Following our review, we find that there is not a need to include provisions on these points because the existing § 112.05-3(c) and the new § 112.05-7(g) both address use of the emergency generator to feedback to non-emergency loads and require either disconnection or automatic load shedding of these loads before the emergency generator is overloaded.

Another commenter was concerned that § 112.05-7(e) appeared to be describing requirements for breaker coordination to main services while using the emergency generator in port. This is true, and this coordination is not a new requirement. Subpart 111.51 requires coordinated protection and selective operation of overcurrent protective devices for all potential plant configurations, including this situation. Section 112.05-7(e) clarifies that in port use of the emergency generator is one of the configurations requiring coordination of overcurrent devices in accordance with § 111.51-5(a). Per the requirements of this rule, the power supply circuits for the use of an emergency generator in port must be arranged and protected to ensure that any electrical fault (except for the emergency generator and the emergency switchboard) will not affect the operation of the main and emergency services. The commenter was concerned this requirement could be interpreted to require full breaker coordination, which they believe is not feasible on many vessels with large distribution breakers from the main switchboard not designed to coordinate with a small power source such as the in-port generator. The commenter requested we remove references to protecting the main power system while using emergency generator in port from these regulations, noting that the intent of the rule is to ensure the availability of the emergency power system if it is being used as the power source while in-port. We understand the commenter's concerns, but, as explained in Section V.E, this provision has been accepted by IMO since 2005 and is similarly addressed in classification society rules. It is true that many of the provisions in this section are aimed at ensuring the availability of the emergency generator in port, but it is also important that the power circuits for the main distribution system are appropriately protected when powered by the emergency generator. We recognize that full coordination may not always be possible because of the large variation in short currents due to different operational conditions, but the coordination study must demonstrate main power system circuits connected to the emergency generator in port are adequately protected against short circuit. For these reasons we did not make any changes to the regulatory text originally proposed for § 112.05-7.

Subpart 112.15—Emergency Loads

§ 112.15-1 Temporary Emergency Loads

As provided in the NPRM, in § 112.15-1 we will now require an engineer's assistance-needed alarm as a required temporary emergency load. A commenter correctly noted that adding the alarm as a temporary emergency load meant that it would also be a final emergency load. This is correct. In accordance with § 112.15-5(a), temporary emergency loads are also final emergency loads.

Regulatory Analysis Comments

A commenter asserted that table 3, “Affected U.S.-Flagged Vessel Population That Complies with 46 CFR Subchapter J,” on page 21462 of the NPRM, does not provide enough clarity to determine whether floating OCS facilities are excluded or included under the vessel count for “Cargo and Miscellaneous Vessels.” The commenter also encouraged the Coast Guard to make changes to the Marine Information for Safety and Law Enforcement (MISLE) database and Coast Guard documentation to ensure this and future rulemakings clarify whether floating OCS facilities are included or excluded.

Another commenter expressed a concern regarding table 3, suggesting that, despite what may be currently listed in MISLE, the latest tally of U.S.-flagged MODUs is less than 5, and likely comprises only the Helix Q4000 and Enterprise Offshore Drilling's EOD 201, and possibly the Spartan Rigs 202 and 303. The commenter suggested we revise table 3 of the proposed rule to read “<5” to more accurately reflect the scope of subchapter J's application to U.S.-flagged MODUs.

We agree with these commenters' assertions that we incorrectly counted the number of Cargo and Miscellaneous Vessels. Our MISLE database listed floating production systems as being inspected under Title 46 of the CFR, subchapter I-A. This is incorrect. As a result, we overstated the number of MODUs in the regulatory analysis (RA) for the proposed rule, which lowered the population of vessels in the “Cargo and Miscellaneous Vessels” category for the final rule. After further analysis, we revised the population of MODUs to one: the Helix Q4000. This is the only MODU in our MISLE database. Therefore, the number of MODUs for the final rule is one because we incorrectly classified the rest based on the subchapter inspection field in MISLE. We added the population of 41 floating production systems in our MISLE database to the final rule RA's category of “Cargo and Miscellaneous Vessels” inspected under subchapter I, which we present in table 4 of the RA. The number of vessels in this category increased from 576 in the proposed rule to 617 in the final rule. Because we updated the entire vessel population for this final rule, the total number of vessels increased from 5,570 in the proposed rule to 5,602 (see table 4).

V. Discussion of the Rule

A. Revisions to § 110.10-1 Incorporation by Reference

The standards that are incorporated by reference in subchapter J are listed in § 110.10-1. With this rule, the Coast Guard updates the technical standards to reflect more recent editions of the standards available to the public. We encourage the use of these updated standards because they reflect the best available technologies, practices, and procedures that are recommended by consensus bodies and other groups with experience in the industry. As the baseline upon which other standards, rules, and equivalency requests are evaluated, it is important that subchapter J incorporates up-to-date references.

We incorporate by reference the class rules of ABS, in particular, in multiple locations within subchapter J and throughout 46 CFR Chapter I. It is important to note that while these rules set the regulatory baseline or standard for specific engineering systems and equipment, the Coast Guard also designated several other authorized classification societies in accordance with 46 CFR part 8. These classification societies are listed on the Coast Guard website.^[5] The Coast Guard authorized the listed classification societies to perform certain functions and certifications using their respective class rules on vessels enrolled in the ACP. Vessels not enrolled in the ACP may propose using the class rules of an authorized classification society as an alternative to the ABS class rules incorporated by reference for particular engineering systems and equipment in accordance with § 110.20-1.

Throughout § 110.10-1, we also add additional standards to provide alternative compliance options, remove outdated standards, and clarify existing requirements. Where applicable, we update the naming format, mailing addresses, phone numbers, and URL addresses for the standards already incorporated by reference. These updates will ensure that the standards are reasonably accessible to the public.

Following this paragraph, we list the standards we are updating, adding, or deleting in § 110.10-1. Within each standard listed, we describe the topics covered by the standard, the changes to the standard, any differences between currently incorporated IBR standards, and a list of the subparts or sections that reference the IBR standard. If this rule does not make any changes to a standard that is currently incorporated by reference, the standard will not be discussed in the revisions to § 110.10-1. However, it will be included, without change, in the regulatory text of § 110.10-1 that appears at the end of this document.

• ABS Rules for Building and Classing Marine Vessels (ABS Marine Vessel Rules), 2020. The rules contain a comprehensive set of construction and maintenance requirements for ships and offshore facilities. The rules are, in general, developed by the International Association of Classification Societies (IACS) and by ABS staff, and reviewed and approved by committees made up of naval architects, marine engineers, shipbuilders, engine builders, steel makers and by other technical, operating, and scientific personnel associated with the worldwide maritime industry. Because of classification society rules' comprehensive nature and ABS's long history of ensuring vessel safety and seaworthiness, they are a valuable supplement to the numerous voluntary consensus standards incorporated by reference. In subchapter J the rules provide an option for the design of engineering systems and components including generators, semiconductor rectifiers, and electric propulsion systems. Specifically, we currently reference the 2003 edition in §§ 110.15-1(b), 111.01-9(b), 111.12-3, 111.12-5, 111.12-7(a) and (b), 111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n), 111.105-39 introductory text and (a), 111.105-40(a) and (c), and 113.05-7(a). In 2020, ABS transitioned from the ABS Steel Vessel Rules to the ABS Marine Vessel Rules. This allowed ABS to consolidate several rules into one foundational rule. We incorporate by reference the 2020 ABS Marine Vessel Rules in the aforementioned sections and additionally in the new § 112.05-7(c) related to use of emergency generators in port. The ABS Marine Vessel Rules undergo an annual review and approval process by ABS technical committees. The Coast Guard participates on these committees, which are comprised of international experts with relevant experience. We are incorporating by reference the following parts of the ABS Marine Vessel Rules: Parts 1, 2, 3, 4, 5A, 5B, 5C, 5D, 6, and 7. Several of the sections of the ABS Marine Vessel Rules that we incorporate by reference have been individually updated. For example:

○ ABS Marine Vessel Rules 4-8-3/Table 2: This table specifies minimum degrees of protection for electrical equipment. This updated table contains several technical updates since the 2003 edition, including additional notes concerning areas protected by fixed water-spray or water mist fire extinguishing systems, and equipment subject to water splash.

○ ABS Marine Vessel Rules 4-8-3: We reference this section for generator construction requirements. The updated edition contains technical updates to account for changes in technology since the 2003 edition.

○ ABS Marine Vessel Rules 4-8-5/5.17.9: This section regarding semiconductor rectifiers now requires a high temperature alarm.

○ ABS Marine Vessel Rules 4-8-5/5.5: This edition contains updates to propulsion generator requirements.

○ ABS Marine Vessel Rules 4-8-2/9.17: This edition updates the requirements for protection of motor circuits to address athwartship thruster motor load alarms and more clearly defines the systems requiring undervoltage release.

○ ABS Marine Vessel Rules 4-8-3/5: This updated section regarding switchboards and motor controllers contains additional cable connection requirements, optional alternative creepage and clearance distances, and additional requirements on battery and uninterruptible power systems based on advancements in technology.

○ ABS Marine Vessel Rules 5-10-4/3: This section regarding roll-on/roll-off cargo spaces is now titled 5C-10-4/3. The new edition made updates to ventilation requirements and to the tables of dangerous goods.

○ ABS Marine Vessel Rules 4-9-7/Table 9: This table regarding equipment testing is now titled 4-9-8/Table 1. The updates to this table reflect changes in technology and industry testing practices.

• ABS Rules for Building and Classing Mobile Offshore Units (ABS MOU Rules), Part 4 Machinery and Systems, 2020. The rules contain a comprehensive set of construction and maintenance requirements for mobile offshore drilling units. In subchapter J the rules provide an option for the design of engineering systems and components including generator, semiconductor rectifier, and electric propulsion systems. Specifically, we currently reference the 2001 edition in §§ 111.12-1(a), 111.12-3, 111.12-5, 111.12-7(c), 111.33-11, 111.35-1, and 111.70-1(a). In 2020, ABS transitioned from the ABS Mobile Offshore Drilling Units Rules to the ABS MOU Rules. This allowed ABS to consolidate several rules into one foundational rule. By means of this rule, we incorporate by reference the 2020 ABS MOU Rules. Like the ABS Marine Vessel Rules, the ABS MOU Rules will undergo a regular review and approval process by the ABS technical committees comprised of international experts with relevant experience. ABS updated and changed the title of several of the ABS MOU rules incorporated by reference in these sections. For example:

○ ABS MOU Rules 4-3-4 (renamed ABS MOU Rules 6-1-7): We reference this section regarding generator construction requirements. ABS made several technical updates since the 2001 edition to account for changes in technology.

○ ABS MOU Rules 4-3-4/3.5.3 (renamed 6-1-7/12): We reference this section for semiconductor converters requirements. ABS made several updates to the standard due to changes in technology.

○ ABS MOU Rules 4-3-4/7.1 (renamed 6-1-7/9.9): We reference this section regarding bus bars and wiring requirements. ABS made several updates to the section since the 2001 edition.

• ANSI/IEEE C37.12-1991—American National Standard for Alternating Current (AC) High-Voltage Circuit Breakers Rated on a Symmetrical Current Basis-Specifications Guide. We remove this standard from § 111.54-1 because IEEE changed the title and republished it with updates in 2008 as IEEE C37.12-2008—IEEE Guide for Specifications of High-Voltage Circuit Breakers (over 1000 V), 2008. This represented a complete technical revision of the standard. IEEE subsequently revised it again in 2018. We incorporate by reference IEEE C37.12-2018 in § 111.54-1 and further discuss this standard with the other IEEE standards incorporated by reference.

• ANSI/IEEE C37.27-1987 (IEEE 331)—Application Guide for Low-Voltage AC Nonintegrally Fused Power Circuitbreakers (Using Separately Mounted Current-Limiting Fuses). We remove the reference to this standard in § 111.54-1 because this guide was replaced by IEEE C37.27—2015—IEEE Guide for Low-Voltage AC (635 V and below) Power Circuit Breakers Applied with Separately-Mounted Current-Limiting Fuses, 2015. We discuss this standard, IEEE C37.27—2015, with the other IEEE standards incorporated by reference.

• ANSI/ISA-RP12.06.01-2003 — Recommended Practice for Wiring Methods for Hazardous (Classified) Locations Instrumentation Part 1: Intrinsic Safety. This recommended practice provides guidance on installation of intrinsically safe systems for use in hazardous (classified) locations. It clarifies and explains the requirements of Articles 504 and 505 of NFPA 70 (National Electrical Code). This recommended practice supersedes ISA RP 12.6-1995. By means of this rule, we delete ISA RP 12.6 from reference in § 111.105-11 and replace it with ANSI/ISA-RP12.06.01-2003.

• ANSI/ISA 12.12.01-2015—Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations. The purpose of this standard is to provide minimum requirements for the design, construction, and marking of electrical equipment or parts of such equipment for use in Class I and Class II, Division 2 and Class III, Divisions 1 and 2 hazardous (classified) locations. This newer edition of the standard replaces ANSI/ISA 12.12.01-2012, which the Coast Guard recently added to § 111.108-3(b) as part of a separate rulemaking titled “Electrical Equipment in Hazardous Locations” (80 FR 16980, Mar. 31, 2015). Additionally, we include ANSI/ISA 12.12.01-2015 in §§ 111.105-3(b) and 111.106-3(b) as another certification option for electrical equipment in hazardous location. The 2015 edition contains minor technical changes from the 2012 edition.

• ANSI/ISA-60079-18—Explosive atmospheres—Part 18: Equipment protection by encapsulation “m”, Third Edition, 2012. This standard gives the specific requirements for the construction, testing, and marking of electrical equipment and parts of electrical equipment, and for the designation of explosion-protected electrical apparatus complying with IEC standards (Ex) components (which is part of an electrical equipment module found in the European hazardous area scheme) with the type of protection encapsulation “m” intended for use in explosive gas atmospheres or explosive dust atmospheres. We currently reference the 2009 edition of this standard in § 111.106-3(d), and the 2012 edition in § 111.108-3(e). This rule removes the ANSI/ISA-60079-18 references in §§ 111.106-3(d) and 111.108-3(e) because the standard has been withdrawn and replaced by UL 60079-18, a substantively similar standard. We replace the ANSI/ISA standard with UL 60079-18 in § 111.106-3(d) and 111.108-3(e).

• API Recommended Practice (RP) 14F—Recommended Practice for Design, Installation, and Maintenance of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class I, Division 1 and Division 2 Locations, Sixth Edition, October 2018. This document recommends minimum requirements and guidelines for the design, installation, and maintenance of electrical systems on fixed and floating petroleum facilities located offshore. By means of this rule, we reference clause 6.8 of the document in § 111.105-17. This clause provides guidance on use of conduit, cable seals, and sealing methods. The incorporation of this standard adds another wiring option in hazardous locations.

• API RP 14FZ—Recommended Practice for Design, Installation, and Maintenance of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities for Unclassified and Class I, Zone 0, Zone 1, and Zone 2 Locations, Second Edition, May 2013. This document recommends minimum requirements and guidelines for the design, installation, and maintenance of electrical systems on fixed and floating petroleum facilities located offshore. By means of this rule, we reference clause 6.8 of the document in § 111.105-17. This clause provides guidance on use of conduit, cable seals, and sealing methods. The incorporation of this standard adds another wiring option in hazardous locations.

• API RP 500—Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Division 1 and Division 2, Third Edition, December 2012 with errata January 2014. This recommended practice provides guidelines for classifying locations at petroleum facilities as Class I, Division 1 and Class I, Division 2 locations for the selection and installation of electrical equipment. We currently reference the second edition (1997) of this standard in §§ 111.106-7(a) and 111.106-13(b). By means of this rule, we reference instead the more recent, third edition (2012) in those sections. The 2012 edition contains editorial changes, but the technical content has not changed.

• API RP 505—Recommended Practice for Classification of Locations for Electrical Installations at Petroleum Facilities Classified as Class I, Zone 0, Zone 1, and Zone 2, Second Edition, August 2018. The purpose of this recommended practice is to provide guidelines for classifying locations Class I, Zone 0, Zone 1, and Zone 2 at petroleum facilities for the selection and installation of electrical equipment. We currently reference the first edition, which was published in 1997 and reaffirmed in 2013, in § 111.106-7(a) and 111.106-13(b). By means of this rule, we reference instead the more recent, second edition (2018) in those sections. This does not substantively change the requirements of those sections.

• ASME A17.1-2016/CSA B44-16—Safety Code for Elevators and Escalators: Includes Requirements for Elevators, Escalators, Dumbwaiters, Moving Walks, Material Lifts, and Dumbwaiters with Automatic Transfer Devices, reissued January 16, 2017 with errata. This code covers the design, construction, operation, inspection, testing, maintenance, alteration, and repair of elevators, hoists, escalators and their associated parts, rooms, and spaces. We currently reference the sixteenth edition (2000) in § 111.91-1. By means of this rule, we reference instead the more recent, twenty-first edition (2016) in that section. ASME updated this standard based on changes in technology. The updated standard addresses new types of elevators being used in the industry, specifically wind turbine elevators and outside emergency elevators. In addition, the standard contains new requirements to address a new feature called “Elevator Evacuation Operation” that allows for the use of elevators for occupant evacuation. Moreover, there are several major changes to the standard that include seismic requirements, updated maintenance control program requirements, and revisions regarding qualifications for elevator inspectors. ASME A17 has been an industry accepted standard since 1921. Although many of the changes to the presently incorporated edition of the standard do not apply to shipboard elevators, it is important that shipboard elevators meet the updated provisions that do apply.

• ASTM B117—19 Standard Practice for Operating Salt Spray (Fog) Apparatus, 2019. This practice covers the apparatus, procedure, and conditions required to create and maintain the salt spray (fog) test environment. Where the Coast Guard's regulations require material to be corrosion-resistant it must meet the testing requirements of this ASTM standard practice. We currently reference the 1997 edition in § 110.15-1(b). By means of this rule, we reference instead the 2019 edition. The 1997 edition has been superseded by several subsequent editions. ASTM made the following changes over the recent editions of this standard that are ultimately incorporated into the 2019 version we adopt in this rulemaking. The testing specifications in the 2011 edition are similar to those in the 1997 edition, but the 2011 edition is more detailed. For example, the impurity restrictions are more detailed in section 8, the air supply requirements are more specific in section 9, and the conditions in the salt chamber are more precisely described in section 10. The 2016 edition added a warning about the impact of water conductivity in section 4 while the 2019 edition added several minor but non-substantive explanatory sections. Overall, the 2019 edition of this testing standard practice for operating salt spray apparatus is very similar to the 1997 edition currently incorporated, with minor improvements in the specifications to ensure testing consistency and precision.

• ASTM F2876-10—Standard Practice for Thermal Rating and Installation of Internal Combustion Engine Packages for use in Hazardous Locations in Marine Applications, Reapproved 2015. This practice covers the method of testing, rating, and installing internal combustion engine packages for use in hazardous areas in marine applications. We currently reference the 2010 edition of this standard in §§ 111.106-3(h) and 111.108-3(g). By means of this rule, we also reference the 2010 edition in new § 111.105-28 regarding internal combustion engines. This ensures a consistent standard for these installations on all vessel and facility types.

• CSA C22.2 No. 30-M1986—Explosion-proof enclosures for use in class I hazardous locations, Reaffirmed 2016. This standard covers the details of construction and tests for explosion-proof enclosures for electrical equipment to be used in Class I, Division 1, Groups A, B, C, and D hazardous locations and in gaseous mines. We currently reference the 1986 edition of this standard in §§ 111.106-3(b) and 111.108-3(b) and by means of this rule incorporate instead the reaffirmed version therein. The two versions are not substantively different. We also reference this reaffirmed standard in § 111.105-3(b), regarding approved equipment, as an additional compliance option. This affords the broadest and most current selection of IBR explosion protection standards for all vessel and facility types.

• CSA C22.2 No. 213-16—Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations, May 2016. This standard provides the details of construction and testing of electrical equipment for use in Class I and II, Division 2 and Class III, Division 1 and 2 hazardous locations. We currently reference the 1987 edition in §§ 111.106-3(b) and 111.108-3(b). By means of this rule, we reference instead the 2016 edition in these sections and also in § 111.105-3(b) concerning approved equipment. This standard received a major revision since the 1987 edition based on advances in technology and changes to related standards. It is an accepted national standard and one of several available standards for nonincendive electrical equipment. Our incorporation of this updated edition ensures use of latest industry practices and including it in § 111.105-3 ensures that standards are consistent for electrical installations on all vessel and facility types.

• CSA-C22.2 No. 0-10—General requirements—Canadian Electrical Code, Part II, including Update No. 2, dated November 2014, Reaffirmed 2015. This standard covers definitions, construction requirements, marking, and tests of a general nature that applies to all or several of the individual standards of the Canadian Electrical Code. We currently reference the ninth edition of this standard in §§ 111.106-3(b) and 111.108-3(b). By means of this rule, we reference instead the tenth edition, reaffirmed in 2015, in these sections and in § 111.105-3(b) concerning approved equipment. The tenth edition includes new requirements for equipment containing lasers or lithium batteries, criteria for the use of adhesives in the construction of electrical equipment, surface temperature limits, attachment plug loading, and the maximum temperature of equipment in contact with gypsum. Additionally, it incorporates a comprehensive list of definitions for use in standards for electrical products and outlines the relationship between this standard and electrical product standards. We incorporate this more recent edition in subpart 111.105 to ensure that standards are consistent for electrical installations on all vessel and facility types.

We currently reference the first edition (1995) of this standard in §§ 111.60-1, 111.60-3, and 111.106-5(a). By means of this rule, we reference the more recent third edition (2017) only in §§ 111.60-1 and 111.106-5(a) because we delete § 111.60-3. The standard has received updates to its construction, performance, ratings, and markings requirements.

• UL 1581—Standard for Safety Reference Standard for Electrical Wires, Cables, and Flexible Cords, 2001. By means of this rule, we delete references to this standard in §§ 111.30-19, 111.60-2, and 111.60-6 because the referenced test in this standard, VW-1, has been moved to UL 2556, which is added to these sections as discussed below.

• UL 1598—Standard for Safety Luminaires, 2018. This standard provides requirements for luminaires for use in nonhazardous locations that are intended for installation on branch circuits of 600 V nominal or less. We currently reference the first edition (2000) of this standard in § 111.75-20. By means of this rule, we reference the more recent fourth edition (2018), which has been extensively updated based on changes in technology and construction techniques. This edition includes added requirements for placement and construction of LED luminaires as well as LED test methods. The standard also includes LED components and subassemblies, and other LED requirements.

• UL 1598A—Standard for Safety Supplemental Requirements for Luminaires for Installation on Marine Vessels, First Edition (with revisions through Apr. 17, 2015), Dec. 4, 2000. UL 1598, the First Edition, December 4, 2000, is currently incorporated by reference in § 111.75-20. By means of this rule, we incorporate UL 1598A, the First Edition with revisions through April 17, 2015 in that section. UL 1598A provides additional requirements for luminaires meeting UL 1598 and intended for vessels to ensure these luminaires are suitable for marine and shipboard environments. The revisions to the First Edition include non-substantive updates necessary due to changes in clauses of standards referenced within UL 1598A that occurred since publication of the First Edition.

• UL 1604—Electrical Equipment for use in Class I and II, Division 2 and Class III Hazardous (Classified) Locations, 1994. This was one of many options in § 111.108-3(b) for standards on electrical equipment in hazardous locations. By means of this rule, we delete this standard from § 111.108-3(b) because UL withdrew this standard and it is no longer active.

• UL 2021—Standard for Safety Fixed and Location-Dedicated Electric Room Heaters, 2015. By means of this rule, we reference this standard in § 111.87-3(a) for the first time. This standard provides requirements for electric air heaters. It will be an additional standard regulated entities may choose for electric air heaters. The Coast Guard has previously accepted it on a case-by-case basis as equivalent to the existing standards in § 111.87-3(a).

• UL 2225—Standard for Safety: Cables and Cable-Fittings for use in Hazardous (Classified) Locations, 2013. This standard contains construction and testing requirements for cables and cable-fittings for use in hazardous locations. We currently reference the second edition (2005) of this standard in § 111.106-3(b) and the third edition (2011) of this standard in § 111.108-3(b). By means of this rule, we reference the more recent fourth edition (2013) in §§ 111.105-3(b), 111.106-3(b), and 111.108-3(b). The latest edition includes the addition of Type TC-ER-HL cable for use in Class I, Zone 1 as permitted by the 2014 National Electrical Code to the scope, editorial revisions, and error corrections. The incorporation of this edition into all three sections ensures consistent, up-to-date standards for electrical installations on all vessel and facility types.

• UL 2556—Wire and Cable Test Methods, 2015. This standard describes the apparatus, test methods, and formulas to be used in carrying out the tests and calculations required by wire and cable standards. The flame retardant test VW-1, formerly of UL 1581, has been moved to this standard and is now called FV-2/VW-1. By means of this rule, we will replace UL 1581 with UL 2556 in §§ 111.30-19(b), 111.60-2, and 111.60-6.

• UL 60079-18—Standard for Safety Explosive Atmospheres—Part 18: Equipment Protection by Encapsulation “m”, Fourth Edition, revised February 20, 2017. By means of this rule, we adopt this standard as a replacement for ANSI/ISA 60079-18, which was withdrawn by ISA. UL 60079-18 is not substantively different than ANSI/ISA 60079-18. This standard gives the specific requirements for the construction, testing and marking of electrical equipment, parts of electrical equipment and Ex components with the type of protection encapsulation “m” intended for use in explosive gas atmospheres or explosive dust atmospheres. We reference this standard in §§ 111.105(e), 111.106-3(d), and 111.108-3(e).

B. Generator Prime Movers

By means of this rule, we will delete the requirements in §§ 111.12-1(b) and (c) for each generator prime mover to have an independent overspeed device and to automatically shut down upon a loss of lubricating oil pressure to the generator bearing. The Coast Guard has required generator prime movers to meet ABS rules since 1965. We incorporate the ABS Steel Vessel Rules for generator prime movers without modification to reduce reliance on government-unique standards where an existing voluntary standard will suffice, as advocated in OMB Circular A-119. The ABS Steel Vessel Rules, which are already incorporated by reference in § 58.01-5,^[6] require these same safeguards on all but small generator prime movers. The independent overspeed device is required for each engine driving a generator of 220 kW (295 horsepower (hp)) and above, while the oil pressure shutdown is required for generators of 100 kW (135 hp) and above. Because vessels will have to comply with the ABS Steel Vessel Rules, there is no need to duplicate these requirements in § 111.12-1, and we find that the requirements in the incorporation by reference sufficiently address the concerns that § 111.12-1(b) and (c) were intended to address.

C. Electrical Cable

This rule updates and amends subpart 111.60 (Wiring Materials and Methods) to align it more closely with the standards accepted internationally by vessel classification societies and foreign administrations.

This rule adds additional acceptable cable construction standards to § 111.60-1. In addition, due to the availability of widely accepted additional standards, this rule removes many of the more prescriptive cable requirements in §§ 111.60-3 and 111.60-4.

We also are rescinding § 111.60-3, which sets out the cable application regulations, because we find that those regulations are unnecessarily prescriptive. Instead, entities will consult the cable construction standards in § 111.60-1, as revised by this rule, for the application of specific types of cable.

In § 111.60-5(a), the Coast Guard currently requires that cable installations meet the recommended practices contained in IEEE 45-2002, and we excluded the section concerning cable splices. Now we will update the edition to IEEE 45.8-2016 and remove the exclusion for the section on cable splices because it is inconsistent with other regulations to exclude them. Both the existing and revised regulations regarding cable splices in § 111.60-19 refer to IEEE 45's recommendations for cable splices.

Additionally, in Table 111.60-7—Demand Loads, we make minor edits so that “bus-tie” and “feeder” are plural where they appear in the table. As previously mentioned in the IBR updates to § 110.10-1, we will also update the NFPA NEC 2002 standard to its newer edition, NFPA 70, where it appears in the table.

In the NPRM, we proposed to update the existing IEEE 45 reference in § 111.60-11(c) to section 5.7 of the 2016 version. A commenter correctly noted this section does not address wire, so we removed section 5.7 of IEEE 45.8 from the list of standards. The final rule leaves the following updated standards to choose from: NPFC MIL-W-76D, ANSI/UL 44, ANSI/UL 83, or an equivalent standard.

D. IEC 60092-502 Electrical Installations in Ships—Part 502: Tankers—Special Features

This rule amends our regulations for hazardous locations contained in Subpart 111.105 to allow the Coast Guard to accept IEC 60092-502:1999 as an option for classification of hazardous locations (areas) in the new § 111.105-50. New section 111.105-50(a) contains an alternative standard for the classification of hazardous locations requirements in §§ 111.105-29, 111.105-31, 111.105-32, 111.106-9 and 111.106-11 of this subchapter. This section provides instructions for how to use the IEC 60092-502:1999 option for the classification of hazardous locations as well as specific requirements for ventilation systems if system designers use IEC 60092-502:1999. This IEC standard is referenced in SOLAS II-1/45.11, the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk section 10.1.1, the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk section 10.1.2.1, and all major classification societies' rules. Allowing this option will provide system designers with the flexibility to classify and specify equipment for hazardous locations using the same scheme used internationally.

IEC 60092-502:1999 is currently accepted for use by vessels in the Coast Guard's ACP when supplemented with “USCG Supplemental Requirements for use of IEC 60092-502:1999 for application of SOLAS regulation II-1/45.11 to U.S.-flag vessels.” ^[7] The Coast Guard developed these supplemental requirements to ensure an equivalent level of safety as the requirements of subpart 111.105. Through this rule, the Coast Guard will accept IEC 60092-502:1999 without the supplement. This edition of the standard has been published for over 15 years, and we are not aware of any casualty history attributed to its use as compared to vessels complying with the applicable U.S. regulations. For these reasons, we will accept it as an option for U.S. vessels.

In § 111.105-50(c), we specify that if IEC 60092-502:1999 is used for hazardous locations classifications, then the applicable ventilation requirements for cargo handling rooms on tank vessels in subchapter D apply. This is not a new requirement, but it is placed here to ensure system designers do not assume that compliance with the ventilation standards in IEC 60092-502:1999 is sufficient. As noted in the discussion of the comment section, this final rule also clarifies that the mechanical ventilation must be capable of at least 30 air changes per hour, based upon the gross volume of the space, for cargo handling or pump rooms and other spaces where hazardous location classification is dependent upon ventilation.

In the final rule, we also break down paragraph (c) into multiple subparagraphs to help with readability. This change is an editorial amendment that does not result in any substantive changes from what we proposed in the NPRM.

E. Emergency Generator in Port

This rule amends our regulations for a vessel's emergency power sources contained in subpart 112.05 to allow the emergency generator to be used in port in the new § 112.05-7. The current regulations in § 112.05-1 require that the emergency source of power must be dependable, independent, and dedicated. The purpose of these requirements in § 112.05-1 is that emergency power must be immediately and dependably available in the event of a loss of the ship's service power. For decades this has been achieved by installation of a dedicated and independent emergency generator.

In the late 1990s, IACS proposed a unified interpretation to the IMO in light of improvements in automation and potential environmental benefits. That proposal incorporated a set of additional safety standards in order to allow the use of an emergency generator during lay time in port. This interpretation, with the supplemental safety standards, would encourage the use of a more appropriately sized generator for lay time loads instead of an overly large ship service generator while simultaneously assuring the availability of emergency power. The IMO subsequently adopted this proposal in 2005, promulgated it in IMO circular MSC/Circ.1176 (dated May 25, 2005), and updated it in IMO circular MSC.1/Circ. 1464/Rev.1 (dated October 24, 2013). Since then, most classification societies and flag states have harmonized their rules to align with this interpretation.

Similar to the IMO, by means of this rule we will allow use of emergency power systems that incorporate a generator with the additional safeguards similar to those prescribed by the IMO. The additional safeguards provide an equivalent level of safety as the existing requirements in part 112 as well as other potential operational benefits. With respect to providing a dependable source of emergency power, operation of the emergency generator in port does not decrease the dependability of the emergency power system. On the contrary, regular operation of the generator with the associated planned maintenance scheme required by MSC.1/Circ.1464/Rev.1 will result in increased dependability and crew familiarity and an improved readiness of the system should an emergency situation occur. Further, the additional requirements related to load shedding, fuel and lubrication oil systems, generator and switchboard construction, power management, and operational instructions will ensure the dedicated and independent operation of this system in an emergent situation and solely provide service to the emergency power system. Overall, this system will deliver additional flexibility to the crew while ensuring the availability of a dedicated source of power in the event of an emergency. The arrangements will result in improved performance, better fuel economy, lower emissions, and higher reliability than less integrated systems.

For these reasons, this rule will allow the emergency generator to be used in port provided that supplemental safety standards are in place. The supplemental safety standards incorporated in § 112.05-7 are similar to those prescribed in MSC.1/Circ.1464/Rev.1 as well as section 4-8-2/5.17 of the ABS Marine Vessel Rules.

F. Description of Additional Changes Within Subchapter J ^[8]

§ 110.15-1 Definitions

This rule adopts a more descriptive definition of “deadship” that aligns with 4-1-1/1.9.6 of the ABS Marine Vessel Rules and IEC 60092-201:2019.

The definition of a ship's service loads and drilling loads are moved from § 111.10-1(a) to § 110.15-1 so that all definitions for subpart J are in one location.

§ 110.25-1 Plans and Information Required for New Construction

We have consolidated the hazardous locations plan submittal requirements of the existing § 110.25-1(i), (p), and (q) into a single section, § 110.25-1(i). The “Offshore Supply Vessels of at Least 6,000 GT ITC” interim rule (79 FR 48893, Aug. 18, 2014) and the “Electrical Equipment in Hazardous Locations” final rule (80 FR 16980, Mar. 31, 2015) included plan submittal requirements, §§ 110.25-1(p) and (q), respectively. As explained in Section V, we will offer all types of vessels and facilities the same selection of explosion protection standards. Therefore, the plan submittal requirements are identical, and three separate sections are no longer required.

This rule makes one addition to the list of required items to be on the plan submission under existing § 110.25-1(i). The plan must clearly indicate the method of classification, Division or Zone, of the hazardous location. This information is important to ensure appropriate selection of equipment for the hazardous location.

§ 111.05-3 Design, Construction, and Installation; General

In § 111.05-3(c), we clarify the grounding requirements for appliances and tools so that the requirements are consistent with current industry practice.

§ 111.10-9 Ship's Service Supply Transformers; Two Required

This rule revises the note to § 111.10-9 to clarify that transformers located downstream of the ship's service switchboard are not required to be provided in duplicate. This item is regularly misunderstood. This revision is consistent with the explanation on page 16 of NVIC 2-89, “Guide for Electrical Installations on Merchant Vessels and Mobile Offshore Drilling Units,” dated August 14, 1989.^[9]

§ 111.12-11 Generator Protection

In this section and many other sections, we replace the term “semiconductor rectifier (SCR)” with “semiconductor converter,” which is a term now more commonly used in industry.

§ 111.12-13 Propulsion Generator Protection

We are deleting this section on propulsion generator protection because it is simply a reference to § 111.35-1. This cross-reference is not necessary.

§ 111.15-10 Ventilation

In § 111.15-10(b)(2)(i), we add the IEC equivalent classification of Class I, Division 1, Group B as an alternate standard.

§ 111.25-5 Marking

Under § 111.25-1, motors are required to meet the requirements for generators in § 111.12-5. That section in turn incorporates by reference section 4-8-3 of the ABS Marine Vessel Rules, which means that motors must meet that standard. Because the ABS Marine Vessel Rules sufficiently address requirements for motor marking, we are deleting this section on motor markings as unnecessary.

§ 111.30 Switchboards

The requirements for switchboards contained in IEEE 45 2002 are replaced with requirements from the recently published IEEE 45.7 (2012), excluding section 6.3.3 related to steering gear circuit overcurrent protection. We did not intend the NPRM to propose a change the existing requirements for steering gear circuit overcurrent protection. For this reason, in § 111.30-5(a)(1) of this final rule, we are incorporating section 6 of IEEE 45.7-2012, excluding section 6.3.3 as discussed above in response to comments received on the NPRM.

In the NPRM, we had proposed a new paragraph (c) that warned readers that the interchangeability and compatibility of components complying with both IEEE and IEC cannot be assumed. That effort was to address the growing use of components meeting IEC standards on U.S. vessels. As noted in the discussion of the comments related to § 111.30-5, we have opted to remove paragraph (c) from the final rule because complying with and enforcing this relatively vague requirement would be difficult. Switchboards should be constructed in accordance with the standards incorporated by reference in subpart 111.30.

The flame retardant test standard IEC 332-1 has been superseded by IEC 60332-1-1:2015 and IEC 60332-1-2:2015. We are updating the standards for the flame retardant test in § 111.30-19(b)(4) regarding buses and wiring accordingly.

This rule replaces the term “pilot light” with the more commonly used term “indicator light.”

Subpart 111.33 Power Semiconductor Rectifier Systems

We are replacing the requirements for semiconductor converters contained in IEEE 45 2002 with requirements from the recently published IEEE 45.2 (2012).

§ 111.50-3 Protection of Conductors

In § 111.50-3(b)(2), we revise the requirement for steering gear circuits from subchapter F to a more specific cite of § 58.25. We also remove the reference to IEC 92-202 from § 111.50-3(c). This standard does not address standard ratings for fuses or circuit breakers.

Subpart 111.51 Calculation of Short-Circuit Currents and Subpart 111.52 Coordination of Overcurrent Protective Devices

This rule combines subparts 111.51 and 111.52 into new subpart 111.51 to more clearly and concisely present the requirements for coordination of overcurrent protection devices and calculation of short-circuit currents. The general discussion contained in current § 111.51-1 is based on IEC 60092-202:2016.

The short-circuit calculations requirements of new § 111.51-2(a) are from the existing § 111.52-1. The new § 111.51-2(b) clarifies that the calculations must be performed to select suitably rated equipment and protective devices. The short-circuit calculations requirements of the new §§ 111.51-3 and 111.51-5 are from the existing §§ 111.52-3 and 111.52-5, respectively.

We are deleting NAVSEA DDS 300-2 from the existing § 111.52-5(b) because it is no longer available. Instead, we add IEC 61660-1:1997 as a standard for DC systems.

The requirements for the protection of vital equipment, § 111.51-6, are from the existing § 111.51-3.

§ 111.54-1 Circuit Breakers

In § 111.54-1(c)(2), the maximum voltage for direct-current circuit breakers meeting IEC 60947-2:2013 will be identified as 1500 V. This is in accordance with that standard.

§ 111.75-17 Navigation Lights

In § 111.75-17(a), this rule removes the requirement that a feeder directly from the emergency switchboard supply the navigation light indicator panel. The emergency switchboard must still supply the panel, but this change allows for the common practice of supplying the navigation lights from an emergency lighting panel rather being directly fed from the switchboard. This is consistent with industry practice and vessel classification society rules. As part of this change we also delete § 112.43-13, which provided details on the navigation light panel feeder.

In § 111.75-17(d)(2), we will offer EN 14744 as an alternative for certification of navigation lights. UL 1104, which is currently the only certification specifically referenced in § 111.75-17(d)(2), is the other acceptable standard, but it has not been updated in over 20 years and addresses neither LED light sources nor EMC testing. EN 14744 addresses LED lights and EMC testing and has been published for 15 years. The other construction and testing requirements of EN 14744 are not identical to UL 1104, but it is accepted worldwide. We are unaware of any safety concerns related to it. For these reasons, we feel it is an acceptable option for certification of navigation lights. The Coast Guard currently accepts navigation lights constructed and tested to the requirements of EN 14744 on a case-by-case basis subject to the additional requirements of the MSC`s Marine Technical Note 01-18, Guidance for Establishing Equivalency to UL 1104 Navigation Lights.^[10] Following the publication of this final rule, we will accept EN 14744 without these additional requirements.

Additionally in § 111.75-17(d)(2), this rule clarifies the requirements for battery powered navigation lights. The existing text has been misinterpreted on occasion. Like all navigation lights, these lights must be certified by an independent laboratory to the applicable requirements of UL 1104, EN 14744, or an equivalent standard. This ensures they meet the applicable requirements of the 1972 COLREGS and the Inland Navigation Rules (33 CFR 83).

This rule deletes the requirement for a flashing light in the existing § 111.75-17(d)(4) because this requirement is contained in section 22.11 of UL 1104 and section 4.4 of EN 14744.

§ 111.75-18 Signaling Lights

This rule deletes the outdated, prescriptive requirements on signaling lights in this section that were based on the applicable international requirements in 1996 and incorporates by reference ISO 25861. This standard provides performance requirements for daylight signaling lamps pursuant to chapter V of SOLAS, 1974, as amended, and chapter 8 of the International Code for Safety for High-Speed Craft. Further, since 2002, navigation equipment required by chapter V of SOLAS, including signaling lamps (or lights), have been required to be type approved by the administration.

§ 111.75-20 Luminaires (Lighting Fixtures)

Throughout this section, we replace the term “lighting fixture” with the internationally used term “luminaire,” and we remove the prescriptive requirements contained in this section. Lighting fixtures meeting the standards incorporated by reference in this section, ANSI/UL 1598A or IEC 60092-306:2009, are suitable for use on vessels. Further, this rule specifies the clauses of ANSI/UL 1598A applicable to nonemergency and inside-type decorative luminaires.

§ 111.83-7 High Voltage Shore Connection

This section contains a standard for HVSCs, IEC/IEEE 80005-1:2019, applicable to ships that connect to shore power. The Coast Guard has actively participated with state and local stakeholders, shoreside and marine industry representatives, and equipment manufacturers to develop a standard to safely connect to HVSCs. This standard is offered as an option for compliance with state or local law, or when a vessel voluntarily connects to an HVSC.

§ 111.99-3 Definitions

We remove this section of definitions because the definitions are no longer necessary. Fire door holding and release systems are discussed in greater detail in SOLAS II-2/9. Many years ago there were detailed fire door system requirements in § 111.99. Now § 111.99-5 requires fire door holding and release systems, if fitted, to meet SOLAS II-2/9.4.1.1.5.3. Previously, § 111.99-5 required these systems to meet SOLAS II-2/30.4.3, but we have updated this reference to SOLAS II-2/9.4.1.1.5.3 based on the reorganization of SOLAS Chapter II-2.

Subpart 111.103 Remote Stopping Systems

The order of the subsections in 46 CFR subpart 111.103 has caused confusion and led readers to incorrectly infer that machinery space ventilation is a separate category from the ventilation referred to by 46 CFR 111.103-7. We are making editorial changes to this section to clarify its intent.

Subpart 111.105 Hazardous Locations

The Coast Guard completed two recent rulemaking projects related to hazardous locations, the “Offshore Supply Vessels of at Least 6,000 GT ITC” interim rule (79 FR 48893, Aug. 18, 2014) and the “Electrical Equipment in Hazardous Locations” final rule (80 FR 16980, Mar. 31, 2015). We are revising subpart 111.105 (Hazardous Locations) to be consistent with existing regulations. This final rule expands the list of acceptable national and international explosion protection standards, providing more options for operators. Additionally, in this final rule, we combine important provisions from §§ 111.105-3, 111.105-5, and 111.105-7 into one revised section, § 111.105-3, titled “Approved Equipment.” In the NPRM, we proposed to only combine §§ 111.105-3 and 111.105-5 into § 111.105-3, but this created confusion among commenters. We decided to also add § 111.105-7 into § 111.105-3 to consolidate all the approved equipment regulations. The reason for this change is discussed previously in response to comments related to § 111.105-3.

We add the internationally accepted independent third-party certification system, the International Electrotechnical Commission System for Certification to Standards relating to Equipment for use in Explosive Atmospheres (IECEx), as an accepted method of testing and certifying electrical equipment intended for use in hazardous locations. Existing § 111.108-1(b) allows owners and operators of existing U.S. MODUs, floating OCS facilities, vessels other than OSVs, and U.S. tank vessels that carry flammable or combustible cargoes, the option of using the same expanded list of standards and the IECEx System. In amending subpart 111.105, we incorporate these standards so that they are available to all vessels and facilities that must comply with subchapter J.

In § 111.105-11, we reduced the number of requirements listed here for intrinsically safe systems because the standards for these systems are now contained in § 111.105-3. Additionally, we are replacing ISA RP 12.6-1995 in the existing § 111.105-11(d) with the standard that supersedes it, ANSI/ISA 12.06.01-2003. This standard is now located in § 111.105-11(b).

In § 111.105-7(a)(1)(i), we add ANSI/ISA 12.12.01 as a new standard for equipment in hazardous locations. See section VI.A for further explanation of this standard. In the NPRM, we also proposed incorporating UL 783 and ANSI/UL 2062 into this section. In the final rule, we have decided not to incorporate these standards by reference because they would have added electrical equipment requirements that were not already required for regulated vessels prior to this rulemaking. We would like to evaluate these standards and their effect on the industry more before considering them for incorporation by reference.

In § 111.105-17(b), we add IEC 61892-7:2019, IEC 60092-502:1999, API RP 14, and API RP 14FZ as additional acceptable standards for the use of conduit. See section VI.A for further explanation of each standard.

In the new § 111.105-28, we add ASTM F2876-10 to address internal combustion engines in hazardous locations. Under the new section, internal combustion engines installed in Class I Divisions 1 and 2 must meet the provisions of ASTM F2876-10. Like the expanded list of standards for electrical equipment in hazardous locations, this standard in subparts 111.106 and 111.108 is the result of previous rulemaking projects and will be added to § 111.105-28. This will ensure a consistent standard for these installations on all vessel and facility types.

In § 111.105-31(e), we are providing the option for submerged cargo pumps that do not meet § 111.105-31(d) to receive concept approval by the Commandant (CG-ENG) and plan approval by the Commanding Officer, MSC. This is consistent with existing §§ 111.106-3(f) and 111.108-3(f).

In § 111.105-31(f), we delete references to IEEE 45 1998 and IEC 60092-502:1999 because they do not provide any additional information on classification of cargo tanks beyond what is currently in subchapter J.

In § 111.105-31(o), we clarify the requirements for systems installed in duct keels.

In §§ 111.105-35 and 111.105-45, we update the IEC classification notation in accordance with IEC 60079-10-2:2015.

In § 111.105-41, we remove the reference to IEEE 45 1998 because the standard has been superseded.

Subpart 111.106 Hazardous Locations on OSVs

In § 111.106-3(b)(1)(i), we incorporate ANSI/ISA 12.12.01 as a new standard for equipment in hazardous locations. See section VI.A for further explanation of this standard. In the NPRM, we also proposed incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided not to incorporate these standards because they would add electrical equipment requirements that were not already required for regulated vessels prior to this rulemaking. We would like to evaluate these standards and their effect on the industry more before considering them for incorporation by reference.

§ 111.107-1 Industrial Systems

In § 111.107-1(b), we clarified the standards for switchgear. Currently § 111.107-1(b)(1) refers to an unnecessarily broad range of standards. We simplify this section by cross-referencing the specific sections of the existing regulations in subpart 111.30 that apply to switchgears.

Subpart 111.108 Hazardous Locations Requirements on U.S. and Foreign MODUs, Floating OCS Facilities, Vessels Conducting OCS Activities, and U.S. Vessels That Carry Flammable and Combustible Cargo

We remove paragraph (b) from § 111.108-1, which was a cross-reference to the expanded list of standards and the IECEx System in subpart 111.105; the paragraph is directed to owners and operators of existing U.S. MODUs, floating OCS facilities, vessels other than OSVs, and U.S. tank vessels that carry flammable or combustible cargoes. This cross-reference to subpart 111.105 is no longer necessary because we include the same standards and systems in § 111.108-3 (General requirements).

In § 111.108-3(b)(1)(i), we add ANSI/ISA 12.12.01 as a new standard for equipment in hazardous locations. See section VI.A for further explanation of this standard. In the NPRM, we also proposed incorporating UL 783 and ANSI/UL 2062 by reference, but we have decided not to incorporate these standards because they would add electrical equipment requirements that were not already required for regulated vessels prior to this rulemaking. We would like to evaluate these standards and their effect on the industry more before considering them for incorporation by reference.

§ 112.01-20 Final Emergency Power Source

We clarify the description of the final emergency power source in this section. For the convenience of the reader, we also cross-reference § 112.15-5, which specifies the existing regulations for final emergency power sources.

§ 112.05-5 Emergency Power Source

In § 112.05-5(a), we clarify that the emergency power source must be sized using a unity (1.0) service factor on all loads as required by Table 112.05-5(a). This section currently states that the emergency power source must simultaneously supply these loads. When sizing the emergency power source to meet this requirement the loads in Table 112.05-5(a) must have a service factor of unity, 1.0 or 100 percent. This is also referred to as a load factor. This is not a change to the existing requirement but only a clarification of the requirement that the emergency power source must be appropriately sized to accomplish this task.

§ 112.15-1 Temporary Emergency Loads

In § 112.15-1(s), we add the engineer's assistance-needed alarm to the list of loads that must be powered by the temporary emergency power source. This is consistent with the requirement in § 113.27-1(c) that states it must be powered from the same source as the general alarm.

§ 112.43-13 Navigation Light Indicator Panel Supply

We delete the requirement that the emergency light indicator panel be supplied directly from the emergency switchboard in this section. We made this change because § 111.75-1(a) will no longer require that a feeder from the emergency generator directly supply the navigation light indicator panel supply and instead allow it to be supplied by an electrical panel, such as an emergency lighting panel, which is supplied by the emergency switchboard.

§ 112.50-1 General

In § 112.50-1(g), we delete the requirement that emergency generators automatically shut down upon loss of lubricating oil pressure. This section will continue to require that generators be set to shut down automatically upon overspeed or operation of a fixed fire extinguishing system in the emergency generator. Removing the requirement for emergency generators to automatically shut down in case of loss of lubricating oil pressure is consistent with classification society rules and allows the crew to decide in an emergency situation if the emergency generator should be shut down. We also reformat § 112.50-1(g) to clarify the remaining regulations for emergency generator set shut downs.

In addition, we revise the format of paragraph (h) to clarify that the alarms are required for all of the listed conditions in each section, not just one of the two conditions listed in each section. This is a non-substantive formatting edit that does not affect the existing alarm regulations for emergency generators in § 112.50-1(h).

VI. Incorporation by Reference

Material that this rule incorporates by reference appears in § 110.10-1, and is summarized and discussed in section V.A of this preamble. Copies of the material are available either at the publisher's web address included in the regulatory text of § 110.10-1 or by contacting the publisher listed in the standard listed in § 110.10-1. We also reviewed and updated all the publisher's web addresses listed in § 110.10-1 to ensure they are current. The following list of publishers offer some of the more recent standards we propose to incorporate at no cost to the public: ABS, FM Approvals, IMO, Lloyd's Register, NFPA, DDS/Military Handbook, and UL. Based on the volume of equivalency requests the Coast Guard receives asking us to confirm that the latest edition is equivalent to or better than the edition currently incorporated, we believe industry already has access to and uses these more recent standards. The affected industry typically obtains the more recent editions of standards in the course of their business, in order to address advancements in technology.

You may also contact the person in the FOR FURTHER INFORMATION CONTACT section for additional direction on how to obtain access to electronic copies of the materials. The Director of the Federal Register approved the material in § 110.10-1 for incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51.

VII. Regulatory Analyses

We developed this rule after considering numerous statutes and Executive orders related to rulemaking. Below we summarize our analyses based on these statutes or Executive orders.

A. Regulatory Planning and Review

Executive Orders 12866 (Regulatory Planning and Review) and 13563 (Improving Regulation and Regulatory Review) direct agencies to assess the costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, of reducing costs, of harmonizing rules, and of promoting flexibility.

Details on the estimated cost savings of this rule can be found in the rule's RA that follows. This rule has not been designated by OMB a significant regulatory action under section 3(f) of Executive Order 12866. Accordingly, OMB has not reviewed it.

The Coast Guard received two public comments regarding the affected population in the RA for the proposed rule. We discuss our responses to these comments in section IV of the preamble of this final rule. We incorporated the commenters' suggestions into the RA for this final rule and revised the population of MODUs and Cargo and Miscellaneous Vessels based on MISLE data. We also updated the total population for the final rule (see table 4). In addition, we updated the mean hourly wage rate using 2021 data from the Bureau of Labor Statistics (BLS). As a result, we revised the estimated cost savings for this final rule. Table 2 summarizes the changes from the NPRM to the final rule and their expected impact on costs and cost savings. The changes we made to the respective CFR sections from the NPRM to the final rule, which we show in table 2, have no additional impact on the affected population or the cost savings we estimated in this analysis.

46 CFR 111.30-5 Construction	46 CFR 111.30-5 Construction	No impact. We are removing the NPRM's proposed paragraph (c), which warned that the interchangeability of IEEE and IEC components could not be assumed. Public comments argued this was confusing and unnecessary.
46 CFR 111.33-1 General	46 CFR 111.33-1 General	No impact, editorial changes. We are changing the word “converter” to “rectifier” to conform with a change proposed for 46 CFR 111.33-3 in the NPRM.
46 CFR 111.40-1 Panelboard standard	46 CFR 111.40-1 Panelboard standard	No impact, editorial changes. We are changing the reference to section 9.10 of IEEE 45.1-2017 to subsection 9.10.1 of IEEE 45.1-2017.
46 CFR 111.60-6 Fiber optic cable	46 CFR 111.60-2 Specialty cable for communication and RF applications, and 46 CFR 111.60-6 Fiber optic cable	No impact, editorial changes. We are restoring existing §§ 111.60-2 and 111.60-6, which were proposed for deletion in the NPRM, and updating standards referenced within these sections to conform with updates proposed in the NPRM.
46 CFR 111.60-11(c) Wire	46 CFR 111.60-11(c) Wire	No impact. We are removing the incorporation by reference of section 5.7 of IEEE 45.8-2016 proposed in the NPRM as this section does not address wire.
46 CFR 111.105-3 General requirements and system integrity	46 CFR 111.105-3 Approved equipment	No impact, editorial changes. We are combining §§ 111.105-3 and 111.105.7 and renumbering paragraphs to improve clarity and consistency with similar requirements elsewhere in subchapter J.
46 CFR 111.105-7 Approved equipment	46 CFR 111.105-3 Approved equipment	No impact. We are combining §§ 111.105-3 and 111.105-7 into § 111.105-3 and removing § 111.105-7.
46 CFR 111.105-11 Intrinsically safe systems	46 CFR 111.105-11 Intrinsically safe systems	No impact, editorial changes. We are adding ANSI/ISA RP12.06.01:2003 because it supersedes ISA RP 12.6 (1995), which was deleted in the NPRM.
46 CFR 111.105-50 Alternative standard to the classification of hazardous locations requirements of this subchapter	46 CFR 111.105-50 Alternative standard to the classification of hazardous locations requirements of this subchapter	No impact, editorial changes. Based on public comments, we are reorganizing and clarifying these requirements.

With this final rule, the Coast Guard will update subchapter J of title 46 of the CFR to align the standards that govern electrical equipment and installations on U.S.-flagged vessels with current industry practices to ensure that the standards are consistent on all vessel types referenced in subchapter J. The provisions of this final rule will update existing standards through incorporation by reference, provide options to use alternative standards, eliminate obsolete standards, and clarify the existing requirements. The majority of the updates will simply incorporate by reference more recent versions of the same standards with little or no substantive change. The more recent editions reflect more modern technologies, terminology, and practices. By updating standards, we expect the final rule to generate cost savings, from a reduction in equivalency requests, to industry and the Federal Government of approximately $209,352 over a 5-year period of analysis in 2021 dollars, using a 7-percent discount rate (we are using a 5-year period of analysis because we anticipate this final rule will not produce cost savings beyond this time period). We estimate annualized cost savings to be approximately $51,059, using a 7-percent discount rate. The cost savings are a result of industry submitting fewer equivalency requests to the Coast Guard (and the Coast Guard, therefore, needing to review fewer equivalency requests), and not from the changes to the IBR standards we make with this final rule. We expect the final rule to generate unquantified benefits because incorporating these standards will simplify regulatory compliance, reduce confusion, and provide industry flexibility. Table 3 provides a summary of the impacts of the final rule.

Affected Population

This final rule affects four parts in subchapter J of title 46 of the CFR (110, 111, 112, and 113), as well as multiple subparts within each part. Subchapter J applies to vessels covered by subchapters D, H, I, I-A, K, L, O, R, and U of title 46 of the CFR.^[11]

We updated the affected population for the final rule because two years have elapsed since we collected the original data for the proposed rule. This final rule will affect approximately 5,602 existing inspected U.S.-flagged vessels. We obtained the affected population of this rule from our MISLE database. For standards we are incorporating by reference in this final rule, we expect all U.S.-flagged vessel owners and operators to use the most recent incorporated standards, some of which were updated as recently as 2020. For construction standards, we expect all U.S.-flagged vessel owners and operators to use the most recent incorporated standards that are in place at the time of construction or modification of a vessel.

For the purpose of the cost savings analysis, we use a subset of the total affected population because only owners and operators of new U.S.-flagged vessels entering service annually will generate cost savings by submitting fewer equivalency requests to the Coast Guard. Included in the total population of 5,602 vessels are 1,460 new U.S.-flagged vessels that entered service in the last 8 years, from 2014 to 2021. We divided 1,460 by 8 years to obtain an average of approximately 183 new U.S.-flagged vessels annually (see table 4 below). We based the cost savings analysis on the past number of equivalency requests owners and operators of new U.S.-flagged vessels submitted to the Coast Guard over an 18-month period from September 2018 to February 2020. The Coast Guard received 10 equivalency requests annually from owners and operators of new vessels during this period. Prior to this time period, the Coast Guard did not collect data on equivalency requests.

We expect this final rule will reduce the baseline number of equivalency requests the Coast Guard receives from industry by 80 percent.^[12] We do not expect this final rule or any updates to standards to eliminate the public's questions altogether; although this rulemaking will update standards, we expect a certain number of standards to be out of date each year because standards organizations are continuously revising standards to reflect safety concerns or to maintain pace with technological advancements within the industry. Thus, we project that about 20 percent of the public still may have questions about the standards they are using annually during the 5-year period and expect the number of equivalency requests that we receive from the public to be about 20 percent of its current annual level. The Coast Guard makes a determination in the year we receive a question (equivalency request) from the public; therefore, the questions will not accumulate from one year to the next. For example, if we characterize the number of questions in the first year as 100 percent of the total amount, we expect this final rule to reduce the number of questions by 80 percent in this year, which produces the cost savings. The balance of 20 percent is the amount that remains, which comprises the number of questions in the first year. In the second year, the public generates additional questions based on the standards they are using, which do not add to the number of questions in the first year. Again, we treat the number of questions in the second year as 100 percent of the total amount, and we expect this final rule to reduce the number of requests by 80 percent in this year, as we explained above. This, again, leaves an amount of 20 percent, which comprises the number of questions in the second year. Essentially, the number of questions in a subsequent year replaces the number of questions the Coast Guard resolves in the preceding year. This process continues through to the fifth year of the analysis period when we expect standards organizations to have completed the process of updating all existing standards.

Specifically, we expect owners and operators of new U.S.-flagged vessels that enter service to submit two equivalency requests annually, or a reduction of eight equivalency requests annually. Owners and operators of new U.S.-flagged vessels submit equivalency requests to the Coast Guard to ask for approval to use a standard that is not in regulation but may be equivalently safe. We explain equivalency requests in greater detail in the Cost Savings Analysis portion of this RA.

This rule continues the Coast Guard's response to the Presidential Regulatory Reform Initiative of Mar. 4, 1995, and directives including Executive Orders 12866 and 13563 that are intended to improve regulation and the regulatory process. The provisions of this final rule will remove obsolete regulations, revise current regulatory text, substitute performance-based options for regulatory compliance as opposed to conventional prescriptive solutions, and incorporate by reference more recent national and international industry standards into the CFR. The Coast Guard recognizes the significant technological advances in electrical engineering equipment, systems, and devices carried on vessels. As a result, this final rule will encourage the use of newer equipment and promote adherence to modern standards in the industry. Industry also will realize cost savings from not having to send equivalency requests to the Coast Guard. See table 4 for how parts of the CFR will be affected by this final rule along with the anticipated impacts.

Benefits of the Rule

Cost Savings Analysis

We divided all of the changes of this final rule into three categories, which we present in table 5: (1) Editorial changes to the CFR, (2) updates to IBR standards with technical changes, and (3) IBR standards with incorporated options or alternative options. The changes we make to the standards incorporated by reference in this final rule will not result in costs or cost savings to industry.

First, we will editorial changes to subchapter J that include such items as the removal of outdated terminology and the consolidation of text in different paragraphs into one paragraph, which includes regulatory provisions in 46 CFR parts 110, 111, 112, 113; we expect these changes to be a no cost change.

Second, we update IBR standards that have technical changes, which includes regulatory provisions in numerous subparts of 46 CFR parts 110, 111, and 113. It is standard practice in vessel manufacturing to follow the most recent editions of standards developed by representative groups of experts using a consensus-based process, because most manufacturers also supply materials to vessels not required to comply with 46 CFR subchapter J. Manufacturers of certain types of electrical equipment carried on vessels are currently producing equipment to the more recent standards, most of which have been published for at least several years and all of which have been developed by standard-based development organizations. These more recent standards, which this final rule adopts, provide greater clarity and specificity than the outdated technical standards they are replacing; therefore, we expect these changes to be a no cost change.

Third, for IBR standards that are one of several available standards as referenced in subchapter J, we update standards with a more recent edition (these will be alternative options) and add standards as new options to the several other available standards for vessel owners and operators and manufacturers of certain types of electrical equipment. The combination of these options will provide industry the opportunity to remove overly prescriptive requirements, simplify regulatory compliance, and provide regulatory flexibility. Many of the options, some of which are alternative options and others of which are new, are IBR standards that affect multiple subparts of 46 CFR parts 110, 111, and 113. The remaining options are not IBR standards and affect multiple subparts of 46 CFR parts 111 and 112. The options we incorporate by reference apply to the same population of 5,602 vessels. We assume industry will use the more recent national and international standards referenced in this rule. We expect adding a revised or new standard, which represents a more recent standard industry that is currently using, as an additional option to the existing standards will be a no cost change because these standards are not requirements; industry can instead choose a given standard to use among different alternative options. See table 5.

Specifically, we adopt the following four changes to subchapter J, related to generator prime movers, electrical cable construction, hazardous locations, and emergency generators, in order to eliminate outdated or unnecessarily prescriptive electrical engineering regulations and add a limited number of alternative standards. Of the four items listed in the following text, the generator prime mover falls into the second category (IBR standards with technical changes), while electrical cable construction, emergency generator, and hazardous locations fall primarily into the third category (IBR standards with proposed and alternative options), which we listed previously.

Generator Prime Mover

This final rule eliminates the regulatory requirements in § 111.12-1(b) and (c) for each generator prime mover to have an independent overspeed device and a loss of lubricating oil pressure to the generator bearing shutdown. The ABS rules, already incorporated by reference in § 111.12-1(a) since 1965, require these same safeguards on all but small generator prime movers. We also incorporate by reference the ABS Steel Vessel Rules for generator prime movers without modification. Industry has been using these rules for many years and the removal of these requirements will not affect the performance of the generator prime mover. We expect this to be a no cost change.

Electrical Cable Construction

For electrical cable construction requirements in subpart 111.60, this final rule incorporates by reference the more recent editions of the 2017 IEC standards and 2017 editions of ANSI standards to ensure alignment with current technological trends and to eliminate several unnecessary prescriptive requirements. This final rule also aligns electrical cable standards in subpart 111.60 with standards accepted internationally by vessel classification societies and foreign administrations and removes unnecessary, prescriptive requirements developed by the Coast Guard, which in turn, will simplify compliance. We expect this to be a no cost change because electrical cables are readily available that meet the standards that we incorporate by reference with this final rule.

Hazardous Locations

This final rule amends subpart 111.105 by incorporating by reference the IEC standard 60092-502 as an alternative standard for classification of hazardous locations. This IEC standard, published in 1999, is referenced in international standards and codes as well as all major classification societies' rules. Because we are adding an alternative standard and not changing requirements with this item, we expect this to be a no cost or no cost savings change.

Emergency Generator

This final rule amends subpart 112.05 to allow vessel owners and operators to use an emergency generator in port. Some U.S.-flagged vessel owners and operators favor the availability of this option in port because it is more fuel-efficient and results in fewer exhaust emissions than using the ship's larger service generators. This option is consistent with international guidance and classification society rules. However, this option applies to a very small number of U.S.-flagged vessel owners and operators who request it, and the Coast Guard will approve the use of an emergency generator for vessel owners and operators in compliance with subchapter J only. We expect this option to have unquantified cost savings associated with it. We also anticipate unquantified benefits due to a decrease in exhaust emissions since an emergency generator uses less fuel than a ship's main generator.

This final rule creates consistency between Coast Guard regulations and national and international standards through incorporation by reference, provides options with alternative standards, eliminates obsolete standards, and clarifies the existing requirements through the changes we adopt in 46 CFR subchapter J. We categorize these changes in table 5, which summarizes the impacts of this final rule and the affected parts and subparts in subchapter J. Consistent with DHS practice, table 5 specifically lists all of the individual changes by part, subpart, and paragraph of 46 CFR subchapter J. Table 1 in section II of the preamble is a general summary of the changes in subchapter J.

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

The Coast Guard evaluated the affected population and estimates that this final rule will generate cost savings for owners and operators of new U.S.-flagged vessels who will no longer submit equivalency requests to the MSC for review. This final rule will also generate cost savings for the Federal Government, which will review fewer equivalency requests. An equivalency request is when an owner or operator of a new U.S.-flagged vessel sends questions to the Coast Guard to ask for a review of the standards they are currently using. Any member of the marine industry may submit a request, but it is primarily submitted by vessel owners and operators. Generally, an owner or operator makes such a request to seek a determination from the Coast Guard on whether or not a standard not contained in Coast Guard regulations is sufficient for use. For example, an equivalent standard could be a more recent edition of a standard in subchapter J, or it could be an alternative standard not currently listed in 46 CFR subchapter J. A Coast Guard Marine Engineer compares the equivalent standard with the standard incorporated by reference in subchapter J to ensure it offers an equal or greater level of safety.

When evaluating the proposed alternative standard, we compare the standard that industry is using to the standard in subchapter J that addresses the type of engineering equipment under review. Typically, owners and operators of existing U.S.-flagged vessels (at the time of construction of a vessel and when a vessel enters service) use the more recent standards in subchapter J, and, therefore they will not likely request an equivalency review from the Coast Guard following this rule. However, the Coast Guard expects owners and operators of new U.S.-flagged vessels that enter service each year to nevertheless have some equivalency questions because they may not be familiar with all of the applicable regulations in subchapter J, which include the most recent standards that are incorporated by reference.

Based on MSC data, the Coast Guard received 15 equivalency requests over the period from September 2018 to February 2020; this is the only period of time for which the Coast Guard maintained equivalency data. This is equivalent to 10 requests annually (15 requests ÷ 18 months × 12 months = 10 requests). We did not receive any public comments concerning this estimate; therefore, we retain the estimate of about 10 requests annually for the final rule. MSC data, validated by CG-ENG, show that a vessel owner or operator typically submits no more than one equivalency request in a given year, no matter how many vessels they may own or operate. Generally, organizations such as UL and the IEC create electrical standards for industry that take into account updates in the latest technology and construction techniques for electrical equipment. These organizations usually review and update standards every 5 years. Therefore, based on a 5-year interval, we generally expect 20 percent of the standards to be out of date in a given year, which, in turn, creates equivalency requests from industry. Because the Coast Guard makes a determination on an equivalency request in the same year it receives the request, we do not expect the number of equivalency questions to accumulate from year to year such that the 20-percent estimate will change in any year of a 5-year period. Even if we publish a rule to address updates to electrical standards in subchapter J, we still expect each year that the public will have questions about the standards it is using, which generates equivalency requests on an annual basis; we do not expect a published rule to eliminate the public's questions altogether.

Industry Baseline Costs

Without this final rule or under the current baseline, the Coast Guard receives approximately 10 equivalency requests annually, as we discussed previously. To draft an equivalency request to the MSC, an owner or operator of a U.S.-flagged vessel seeks the services of an engineering design firm or a shipyard's technical staff for a Marine Engineer or Naval Architect. Using the BLS “Occupational and Employment Statistics” database and May 2021 wage estimates, the unloaded mean hourly wage rate for Marine Engineers and Naval Architects is $47.03 (occupational code 17-2121).^[13] To account for an employee's non-wage benefits, we apply a load factor to the unloaded mean hourly wage rate, which we calculated by using BLS's “Employer Cost for Employee Compensation” database. We determined the load factor to be approximately 1.48, rounded.^[14] We multiply $47.03 by 1.48 to obtain a loaded mean hourly wage rate of approximately $69.60 for this occupation.

Based on information from the MSC and validated by subject matter experts in CG-ENG, it takes a Marine Engineer or Naval Architect approximately 40 hours of time to develop an equivalency request and submit it to the Coast Guard for review, which includes the electronic submission.

We estimate the total undiscounted cost for industry to submit 10 equivalency requests annually to be approximately $27,840, or $2,784 for each request (10 equivalency requests × $69.60 × 40 hours per request). See table 6 for industry inputs.

Federal Government Baseline Costs

When the Coast Guard receives an equivalency request from a vessel owner or operator (or an electrical equipment manufacturer), the Coast Guard personnel at the MSC must review the request to provide a determination on whether or not the proposed standard is equivalent to a standard found in subchapter J. Based on information from the MSC and validated by subject matter experts in CG-ENG, a civilian Coast Guard Marine Engineer needs about 32 hours to review an equivalency request. Based on 10 requests received annually, the Coast Guard expends approximately 320 hours annually to review these requests. A Coast Guard Marine Engineer typically has a Federal Government General Schedule (GS) grade level of GS-14. The Office of Personnel Management lists the hourly pay for Federal employees who work in the Washington, DC area on its website, and records the hourly pay of a person with the grade level of a GS-14, step 5 (the midpoint of the pay grade) as $66.54.^[15] We then calculate the share of total compensation of Federal employees to account for a Government employee's non-wage benefits. The Congressional Budget Office reports total compensation to Federal employees to be $64.80 per hour and wages to be $38.30.^[16] We determine the load factor to be approximately 1.69 ($64.80 ÷ $38.30). We multiply $66.54 by 1.69 to obtain a loaded hourly wage rate of approximately $112.45 for a GS-14 Senior Engineer (Marine Engineer or Naval Architect). We estimate the total, undiscounted cost for the Federal Government to review 10 equivalency requests annually to be approximately $35,984 (10 equivalency requests × 32 hours for each request × $112.45), or $3,598 for each request. See table 7 for the Federal Government inputs.

We estimate the total, undiscounted baseline cost to industry and the Federal Government to submit and review equivalency requests, respectively, to be approximately $63,824 ($27,840 + $35,984), annually. Table 8 presents a summary of the baseline costs associated with industry submitting equivalency requests to the Coast Guard.

Industry Cost Savings

The baseline costs we estimate for industry is from vessel owners and operators of new U.S.-flagged vessels that enter service each year who submit equivalency requests. We expect this rule will reduce the number of equivalency requests industry submits annually. We estimate 195 companies own the average number of 183 new U.S.-flagged vessels that have entered service each year in the past 8 years. The number of equivalency requests the Coast Guard has received annually from these owners and operators is approximately 10 (a vessel owner or operator will request an equivalency determination without regard to the number of vessels owned). We anticipate standards organizations to update their standards every 5 years. Therefore, we expect 20 percent of the standards to be out of date in a given year over this period of time (100 percent divided by 5 years equals 20 percent). We multiplied the 20 percent value by the baseline number of 10 equivalency requests the Coast Guard receives annually from owners and operators of new U.S.-flagged vessels. Therefore, we expect industry to submit 2 equivalency requests (10 equivalency requests × 0.20) in any given year of the analysis period, or a reduction in the number of requests of 80 percent. Similarly, the marine industry will save approximately 320 hours annually from not drafting and submitting equivalency requests (320 hours = 8 requests × 40 hours for each request). The submission of an equivalency request will not affect or change an existing information collection request, nor will it create a new one, because we estimate the number of requests to be approximately 2 annually, which is below the threshold of 10 limit set by the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The Federal Government does not require the marine industry to submit these requests; vessel owners and operators (or manufacturers) voluntarily submit requests only if they have questions about the standards they are using.

Using the same labor category previously used to calculate the baseline for industry costs, we estimate the total undiscounted cost savings of this rule to industry to be approximately $22,272 annually [(10 equivalency requests × 40 hours for each equivalency × $69.60 = $27,840) minus (2 equivalency requests × 40 hours for each equivalency request × $69.60 = $5,568)]. We estimate 5-year cost savings of this rule to industry to be approximately $91,320, using a 7-percent discount rate. We estimate the annualized cost savings to be approximately $22,272, using a 7-percent discount rate, as shown in table 9.

Federal Government Cost Savings

With this final rule, we expect the Coast Guard will review annually 2 equivalency requests (10 equivalency requests × 0.20). This again will be a reduction of 80 percent from the baseline number of 10 requests. With fewer equivalencies to review, the Coast Guard will also save approximately 256 hours annually from not reviewing equivalency requests (8 requests × 32 hours per request).

Using the same labor category previously for MSC personnel to review an equivalency request, we estimate the total, undiscounted cost savings of this final rule to the Federal Government to be approximately $28,787 annually [(10 baseline equivalency requests × 32 hours for each equivalency request × $112.45 = $35,984) minus (2 equivalency requests × 32 hours for each equivalency request × $112.45 = $7,197)]. We estimate the 5-year discounted cost savings of this rule to the Federal Government to be approximately $118,032, using a 7-percent discount rate. We estimate the annualized cost savings to be approximately $28,787, using a 7-percent discount rate, as shown in table 10.

Total Cost Savings of This Rule

We estimate the 5-year, total discounted cost savings of this final rule to be approximately $209,352 ($91,320 + $118,032), using a 7-percent discount rate. We estimate the annualized cost savings of this rule to be approximately $51,059, using a 7-percent discount rate. The total annualized cost savings is the summation of the values in tables 9 and 10 ($22,272 + $28,787 = $51,059) as a result of the reduction in the number of equivalency requests we expect annually from industry, as shown in table 11.

Annualized Cost Savings, 7%	22,272	28,787	51,059

Unquantified Cost Savings of the Final Rule

We expect this final rule will have unquantified cost savings associated with the option of using an emergency generator while in port. The use of an emergency generator in port will likely save fuel because it does not require a vessel owner or operator to use a ship's larger service generators. However, we are not able to quantify the cost savings associated with this option because the Coast Guard does not have the data to predict how many vessel owners and operators will choose this option while in port. Nevertheless, we expect at least a small number of vessel owners and operators to choose this option.

Additionally, we expect this final rule to generate qualitative benefits. This final rule is necessary because it will update obsolete standards, remove redundancy in regulatory text, clarify and rearrange regulatory text, and provide options to owners and operators of vessels and manufacturers of certain types of electrical equipment. By updating standards and providing options, Coast Guard regulations will be less ambiguous and conform to the more recent industry standards, thereby ensuring consistency within the marine industry. Some of these options we consider to be alternative options, and others will be new options. With these changes, industry will follow less ambiguous regulatory provisions, which we expect will create fewer equivalency requests. In addition, we removed Coast Guard prescriptive requirements in some places and replaced them with more recent national or international standards, which should simplify compliance.

Regarding the use of an emergency generator while in port, this option will likely reduce emissions and save fuel for vessel owners and operators who choose to use an emergency generator while in port. Some U.S.-flagged vessel owners and operators favor the availability of this option in port because it is more fuel-efficient and results in fewer exhaust emissions than using the larger ship's service generators. This will be an option for a very small number of U.S.-flagged vessel owners and operators who request it. This option is consistent with international guidance and classification society rules. The Coast Guard will approve the use of an emergency generator for vessel owners and operators in compliance with subchapter J only.

We are not able to quantify the expected reduction in the exhaust emissions because the Coast Guard is not able to predict how many vessel owners and operators will choose this option while in port due to the lack of data. The Coast Guard did not receive any public comments on the proposed rule concerning cost or cost savings associated with the use of an emergency generator and exhaust emissions while a vessel is in port.

(1) Industry would continue to meet the current standards in 46 CFR subchapter J with no updates to standards or incorporations by reference (current baseline without regulatory action).

This alternative is a representation of the current state of the industry where vessel owners and operators would continue to follow standards in 46 CFR subchapter J without any updates to standards. To use a newer standard or alternative standard, industry must submit an equivalency request, and the Coast Guard must grant that equivalency. With this alternative, industry would not benefit from regulations incorporating newer or alternative standards and would not benefit from the latest advances in electrical equipment technology without incurring the cost of submitting equivalency requests. With this alternative, there would be no change in the costs.

With this alternative, we would not update the standards in 46 CFR subchapter J, and industry would not follow the more recent standards, which includes technological advancements in electrical equipment carried on vessels. We rejected this alternative because it would not create cost savings for the marine industry and industry also would not benefit from this alternative because it would not provide needed regulatory clarity.

(2) Issuance of a policy letter that would permit the marine industry to meet the more recent editions of the IBR standards without updating the editions that are incorporated by reference in 46 CFR subchapter J.

For this alternative, we would issue a policy letter that would permit industry members to meet the most recent editions of the pertinent standards. With such a policy in place, we anticipate that the marine industry would use the more recent editions of the IBR standards. However, 46 CFR subchapter J would still contain outdated standards and overly prescriptive regulations that we could only remove through notice and comment rulemaking. Issuing a policy letter would not provide the agency an opportunity for soliciting public comment on current industry practice and standards. Additionally, the policy letter would not be enforceable against the public, and the Coast Guard could revise the policy letter without opportunity to comment.

We would expect the number of equivalency requests to decrease with this alternative by the same amount as the preferred alternative, and we also expect the cost savings associated with this alternative to be the same as the preferred alternative. We estimate this alternative would save industry approximately $22,272 annually (undiscounted). We estimate the 5-year discounted cost savings of this alternative to industry would be approximately $91,320, using a 7-percent discount rate. We estimate the annualized cost savings would be approximately $22,272, using a 7-percent discount rate. We rejected this alternative because we would not be incorporating by reference the more recent standards in the CFR, industry would not benefit from enhanced regulatory clarity in subchapter J, and the public would not be given the opportunity to comment on the appropriateness of the more recent editions of the IBR standards.

(3) Preferred Alternative—Update the IBR standards in 46 CFR subchapter J, create regulatory options, and make editorial changes to reduce the ambiguity that currently exists.

With this alternative, we will update the current standards in 46 CFR subchapter J and incorporate the more recent industry standards. This is the preferred alternative because it will create consistency between Coast Guard regulations and national and international standards, update the standards incorporated by reference to reflect the more recent standards available, provide options for alternative standards, eliminate obsolete standards, and clarify the existing requirements.

This alternative will reduce the number of equivalency requests from the marine industry and create cost savings for vessel owners and operator and manufacturers of marine equipment. It will also reduce the hours the marine industry will spend on drafting and submitting equivalency requests to the Coast Guard. We analyzed and presented the cost saving impacts of this alternative to industry and the Coast Guard earlier in this RA.

B. Small Entities

Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 601-612) (RFA), we have considered whether this final rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000.

This rule creates cost savings for industry because we estimate fewer equivalency requests will be submitted to the Coast Guard. We expect equivalency requests to be submitted by owners or operators of new U.S.-flagged vessels who may have questions about standards that are not in 46 CFR subchapter J. Over an 8-year period from 2014-2021, we found 1,460 new U.S.-flagged vessels entered service, or an average of approximately 183 annually during this period. We found that 195 companies owned the 1,460 vessels.

Using the publicly-available online database “ReferenceUSAgov” (in addition to individual online searches of companies) to search for company-specific information such as annual revenues and number of employees, we found revenue or employee information on 119 of the 195 companies, or approximately 61 percent.^[17] Using the Small Business Administration's “Table of Size Standards” and the North American Industry Classification System codes listed in the table, we found 88 of the 119 companies to be small entities.^[18] We found the other 31 companies to be not small.^[19] We did not find information on the remaining 76 companies; therefore, we assumed these companies to be small entities for a total of 164 small entities out of 195 companies, or approximately 84 percent.

We analyzed the potential economic impacts of this final rule on small entities and found that each small entity that no longer submits an equivalency request will save approximately $2,784 annually. We estimate an 80 percent reduction in the number of equivalency requests (from 10 to 2 annually) industry submits to the Coast Guard with this rule; therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this final rule will not have a significant economic impact on a substantial number of small entities.

Any small entity that does not submit an equivalency request will not be impacted by any costs or cost savings.

C. Assistance for Small Entities

Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we offer to assist small entities in understanding this rule so that they can better evaluate its effects on them and participate in the rulemaking. The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard.

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

D. Collection of Information

The Paperwork Reduction Act of 1995 (44 U.S.C. 3507(d)) requires the U.S. Coast Guard to consider the impact of paperwork and other information collection burdens imposed on the public. The Coast Guard has determined that there will be no new requirement for the collection of information associated with this final rule.

E. Federalism

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

It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 8101 (design, construction, alteration, repair, maintenance, operation, equipping, personnel qualification, and manning of vessels), as well as the reporting of casualties and any other category in which Congress intended the Coast Guard to be the sole source of a vessel's obligations, are within the field foreclosed from regulation by the States. See United States v. Locke, 529 U.S. 89, 115-116 (2000) (holding that Congress intended that the Coast Guard regulations be the sole source of vessel design, operation, and reporting requirements). This proposed update to electrical engineering standards for vessels is issued under the authority in 46 U.S.C. 3306(a)(1), which authorizes the Secretary to prescribe regulations for the design, construction, alteration, repair, and operation of vessels subject to inspection, including equipment, appliances, propulsion machinery, auxiliary machinery, boilers, unfired pressure vessels, piping, and electric installations. Therefore, because the States may not regulate within these categories, this rule is consistent with the fundamental federalism principles and preemption requirements described in Executive Order 13132.

F. Unfunded Mandates

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

G. Taking of Private Property

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

H. Civil Justice Reform

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

I. Protection of Children

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

J. Indian Tribal Governments

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

K. Energy Effects

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

L. Technical Standards and Incorporation by Reference

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

The sections that reference these standards and the locations where these standards are available are listed in § 110.10-1.

This rule also uses technical standards other than voluntary consensus standards. These are not government-unique standards but rather standards issued by the International Maritime Organization and two vessel classification societies, all of which have a long history of developing standards to ensure vessel safety and seaworthiness. Additionally, we incorporate several military specifications that are extensively used by the maritime community.

M. Environment

We have analyzed this 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 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 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 rule is categorically excluded under paragraphs L54 and L57 of Appendix A, Table 1 of DHS Instruction Manual 023-01-001-01, Rev. 01. Paragraph L54 pertains to regulations that are editorial or procedural. Paragraph L57 pertains to regulations concerning manning, documentation, admeasurement, inspection, and equipping of vessels.

This rule involves incorporating by reference several updated electrical engineering standards along with removing several outdated or unnecessarily prescriptive electrical engineering regulations.

6.  We note that § 58.01 currently incorporates by reference the 2003 edition of the ABS Steel Vessel Rules. On October 18, 2021 we proposed in Updates to Marine Engineering Standards, 86 FR 57896 (Oct. 19, 2021) (proposed rule) to update the reference in § 58.01 to the 2020 edition of the ABS Marine Vessel Rules.. This is the same edition incorporated by reference in § 110.10-1(a). If we amend § 58.01 through a final rule on this same topic, any changes made would not conflict with the intent of § 111.12-1. Generator prime movers will have to meet the ABS Marine Vessel Rules incorporated by reference in § 58.01.

8.  In addition to the changes specifically discussed in this preamble, we note that we have made additional non-substantive edits for clarity following the NPRM. For example, we removed the word “both” in § 111.87-3 because, following the addition of a new standard as discussed elsewhere in this rule, “both” was no longer an accurate description.

11.  Title 46 CFR subchapter J lists two other subchapters, Q and W. Subchapter Q does not contain vessels; it applies to vessels in the other subchapters regarding equipment, construction, and materials for specifications and approval. Similarly, subchapter W does not contain vessels but applies to vessels that have lifesaving appliances and arrangements in one of the subchapters previously listed.

12.  Generally, standards are updated every 5 years. We therefore assume that 20 percent of the standards become outdated each year as time elapses, so 100 percent/5 years = 20 percent annually (outdated standards). So, the remaining80 percent (100 percent−20 percent) will generate the cost savings.

13.  Visit https://www.bls.gov/​oes/​2021/​may/​oes172121.htm to find 2021 unloaded mean hourly wage rate for occupations in the United States.

14.  A loaded hourly wage rate is what a company pays per hour to employ a person, not the hourly wage an employee receives. The loaded hourly wage rate includes the cost of non-wage benefits (health insurance, vacation, etc.). To obtain the load factor, we used the multi-screen data search feature from this database and searched for “private industry workers” under “total compensation” and then for “all workers” in the category “Transportation and Materials Moving Occupations,” within the United States. We performed the same steps to obtain the value for “wages and salaries.” The series IDs for total compensation, and wages and salaries are CMU2010000520000D and CMU2020000520000D, respectively, which are not seasonally adjusted values. Using second quarter data for 2021, we divided the value for total compensation, $31.90, by wages and salaries, or $21.54, to obtain a load factor of about 1.48, rounded. https://data.bls.gov/​cgi-bin/​dsrv?​cm.
