III. Executive Summary

When writing regulations that set technical standards, the Coast Guard relies as much as possible on existing industry consensus standards. Doing so minimizes proliferation of differing standards and complies with the National Technology Transfer and Advancement Act and OMB Circular A-119. The legal method of directing

regulated entities to follow separately published standards is called incorporation by reference (IBR). This notice of proposed rulemaking (NPRM) proposes to update prior incorporations by reference, add a limited number of alternative standards, and eliminate outdated or unnecessarily prescriptive regulations in title 46 of the Code of Federal Regulations (CFR) subchapter J.

This proposed rule would update the standards incorporated by reference (IBR) in both 46 CFR 110.10-1 and all of the sections in subchapter J that reference the updated IBR standards. More specifically, this proposed rule would incorporate the more recent editions of many standards, incorporate by reference additional standards for certain topics, and remove 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, we propose the following four changes to subchapter J.

First, this proposed rule would eliminate 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 would continue to be required to meet standards of the American Bureau of Shipping (ABS) Steel Vessel Rules.

Second, this proposed rule would simplify 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.

Third, for classifications of hazardous locations in subpart 111.105, this proposed rule would accept 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 proposed rule would amend 46 CFR 112.05 to allow the use of an emergency generator in port. This optional capability to use emergency generators in port would be 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 proposed changes and the affected sections.

IV. Basis and Purpose

The legal basis of this proposed rulemaking is section 1333(d) of Title 43, United States Code (U.S.C.), sections 3306 and 3703 of Title 46 U.S.C., and the Department of Homeland Security (DHS) Delegation No. 0170.1. 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. Section 46 U.S.C. 3306(a)(1) authorizes the Secretary to prescribe regulations for the design, construction, alteration, repair, and operation of vessels subject to inspection, including equipment, appliances, propulsion machinery, auxiliary machinery, boilers, unfired pressure vessels, piping, and electric installations. Additionally, 46 U.S.C. 3703 grants the Secretary authority to regulate the construction, alteration, repair, maintenance, operation, and equipping of vessels, that may be necessary for increased protection against hazards to life and property, for navigation and vessel safety, and for enhanced protection of the marine environment. These authorities have been delegated to the Coast Guard by the DHS Security Delegation No. 0170.1(II)(92)(b).

The purpose of this proposed rulemaking is to update the standards that are 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 (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 proposed 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.

V. Background

Title 46 CFR subchapter J 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. The IBR section in subchapter J was last amended by the 2015 final rule titled “Electrical Equipment in Hazardous Locations” (80 FR 16980, Mar. 31, 2015), but because of its limited scope, that rule did not update all of the standards to reflect newer editions. Many of the IBR standards have not been updated since 2008 when the Coast Guard issued the final rule titled “Review and Update of Standards for Marine Equipment” (73 FR 65156, Oct. 31, 2008).

Furthermore, the interim rule titled “Offshore Supply Vessels of at Least 6,000 GT ITC” (79 FR 48893, Aug. 18, 2014) and the “Electrical Equipment in Hazardous Locations” final rule (80 FR 16980, Mar. 31, 2015) amended subchapter J by adding the hazardous location regulations in subparts 111.106 and 111.108 for types of vessels and facilities not covered under subpart 111.105. Vessels and facilities regulated under 111.106 and 111.108 have a broader and more current selection of IBR standards because there were more recent standards to include with those rulemakings. This proposed rule would amend subparts 111.105, 111.106 and 111.108 to ensure all vessel types are offered the broadest and most current selection of IBR explosion protection standards.

Shipboard electrical systems are becoming increasingly complex due to the development of power electronics and computer control systems. In response, many of the standards incorporated by reference have been superseded by newer editions to address the newer electrical equipment. In some cases, the later editions reflect more modern technologies, terminology, and practices that are already in use by industry. Adopting newer versions of these standards would reduce the number of equivalency requests from industry to the Coast Guard, which is expected to produce cost savings. The incorporation of more recent editions also ensures the latest industry practices and advancements in technology are addressed in regulations.

VI. Discussion of Proposed Rule

A. Proposed Revisions to § 110.10-1 Incorporation by Reference

Currently, all of the standards that are incorporated by reference in subchapter J are listed in § 110.10-1. Within this section, the Coast Guard proposes to update the technical standards to reflect the 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.

The class rules of the American Bureau of Shipping (ABS), in particular, are incorporated by reference 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.

1

The Coast Guard authorized the listed classification societies to perform certain functions and certifications using their respective class rules on vessels enrolled in the Alternate Compliance Program. Vessels not enrolled in the Alternate Compliance Program 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 propose additional standards to provide alternative compliance options, remove outdated standards, and clarify existing requirements. Where applicable, this proposed rule would also 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 propose to update, add, or delete in § 110.10-1. Within each standard listed, we describe the topics covered by the standard, the proposed 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 proposed rule does not propose any changes to a standard that is

currently incorporated by reference, the standard will not be discussed in the proposed revisions to § 110.10-1. However, it will be included, without change, in the proposed regulatory text that appears at the end of this document.

ABS Rules for Building and Classing Marine Vessels (ABS Marine Vessel Rules), 2020.

The ABS is a vessel classification society that develops and publishes rules for the construction and maintenance of ships and offshore facilities. Subchapter J references these rules in numerous sections as an option for the design of certain systems 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, 111.33-11, 111.35-1, 111.70-1(a), 111.105-31(n), 111.105-39(a), 111.105-40, 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 propose to incorporate by reference the 2020 ABS Marine Vessel Rules in the aforementioned sections and additionally in the new proposed § 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. Several of the sections of the ABS Marine Vessel Rules that we propose to 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 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.

ABS also develops and publishes rules for the construction and maintenance of mobile offshore drilling units. Subchapter J references these rules in numerous sections as an option for design of certain systems 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. We propose to 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.

American National Standards Institute (ANSI) and Institute of Electrical and Electronic Engineers (IEEE) 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 propose to 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 1,000 Volts), 2008. This represented a complete technical revision of the standard. IEEE subsequently revised it again in 2018. We are proposing to 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 are proposing to 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/International Society of Automation (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 would replace 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 propose to include ANSI/ISA 12.12.01-2015 in §§ 111.105-7(a) 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 proposed rule would remove the ANSI/ISA-60079-18 references in §§ 111.106-3(d) and 111.108-3(e) because it has been withdrawn and replaced by UL 60079-18, a substantively similar standard. We propose replacing the ANSI/ISA standard with UL 60079-18 in § 111.106-3(d) and 111.108-3(e).

○ Revisions to address the equivalent installation and use of Class I, Division 1 and Class II, Division 1 intrinsically safe and associated apparatus in Class I, Zone 0 and Zone 20 hazardous (classified) locations respectively; and

○ Revisions to dust-tight enclosures for Class II Intrinsically Safe Apparatus.

UL 1042—Standard for Safety Electric Baseboard Heating Equipment, 2009.

This standard provides requirements for portable and fixed electric baseboard heating equipment rated at 600 V or less. We currently reference the third edition (1994) of this standard in § 111.87-3. We propose to reference the more recent, fifth edition (2009). This latest edition includes the following technical revisions:

○ Revisions requiring portable heater power supply cords to meet UL 817.

○ Revisions requiring electric connections to meet established UL standards, UL 310, UL 486A-486B, UL 886C, UL 486E, or UL 1977.

○ Revisions to equipment grounding provisions.

○ Update to the leakage current test.

•

UL 1072—Standard for Safety Medium-Voltage Power Cables, 2006.

This standard provides requirements for

shielded and nonshielded medium-voltage power cables. We currently reference the third edition (2001) of this standard in § 111.60-1(a). We propose to reference the more recent fourth edition (2006). The fourth edition contains revised supplemental jacket thicknesses. Because supplemental jackets are only required for cables intended to be buried in the ground, this revision has no substantive impact on UL 1072 cables intended for use on vessels.

•

UL 1104—Standard for Marine Navigation Lights, Second Edition, 1998.

This standard provides construction and testing requirements for navigation lights. This standard is referenced in § 111.75-17(f). The only changes proposed to this standard are to align the naming convention in the regulatory text with that of other UL standards and to specifically cite paragraph (f).

•

UL 1203—Standard for Safety: Explosion-Proof and Dust-Ignition Proof Electrical Equipment for Use in Hazardous (Classified) Locations, 2013.

This standard covers explosion-proof and dust-ignition-proof electrical equipment for installation and use in hazardous locations. We currently reference the third edition (2000) of this standard in § 111.105-9 and the fourth edition (2006) in §§ 111.106-3(b) and 111.108-3(b). We propose to reference the more recent fifth edition (2013) in § 111.105-7(a) instead of § 111.105-9 due to editorial reformatting of §§ 111.105-7(a), 111.106-3(b), and 111.108-3(b). The more recent edition has relatively minor technical clarifications with minimal substantive changes.

•

UL 1309—Standard for Safety Marine Shipboard Cables, 2017.

This standard provides requirements for distribution (power) cables, and control and signal cables, for installation aboard marine vessels, fixed and floating offshore petroleum facilities, and Marine Offshore Drilling Units (MODUs). We currently reference the first edition (1995) of this standard in §§ 111.60-1, 111.60-3, and 111.106-5(a). We propose to reference the more recent, third edition (2017) only in §§ 111.60-1 and 111.106-5(a), because we are proposing to 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.

We propose to 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.

•

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. We propose to 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 light-emitting diode (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.

The First Edition, December 4, 2000, is currently incorporated by reference in § 111.75-20. We propose to incorporate the First Edition with revisions through April 17, 2015 in this 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 to 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.

We propose to delete this standard from § 111.108-3(b) because UL withdrew it and it is no longer an active standard. This is one of many options in § 111.108-3(b) for standards on electrical equipment in hazardous locations.

•

UL 2021—Standard for Safety Fixed and Location-Dedicated Electric Room Heaters, 2015.

We propose to reference this standard in § 111.87-3(a). This standard provides requirements for electric air heaters. It will be an additional standard regulated entities may choose for electric air heaters. We have 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.

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). We propose to reference the more recent fourth edition (2013) in §§ 111.105-7(a), 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 sections of the standard. 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. We propose to replace the UL 1581 with UL 2556 in § 111.30-19(b).

•

UL 60079-18—Standard for Safety Explosive Atmospheres—Part 18: Equipment Protection by Encapsulation “m”, 2017.

We propose this standard as a replacement for the ANSI/ISA 60079-18, which was withdrawn. 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 propose to reference this standard in §§ 111.105-7(e), 111.106-3(d), and 111.108-3(e).

B. Generator Prime Movers

We propose to delete the 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 oil pressure shutdown. The ABS Steel Vessel Rules, which are already incorporated by reference in § 58.01-5, 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 hp) and above, while the oil pressure shutdown is required for generators of 100 kW (135 hp) and above. This sufficiently addresses the concerns that § 111.12-1(b) and (c) were intended to address. The Coast Guard has required generator prime movers to meet ABS rules since 1965. We propose to 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.

C. Electrical Cable

We propose to update and amend subpart 111.60 (Wiring Materials and Methods) to align it more closely with the standards accepted internationally by vessel classification societies and foreign administrations. Vessels participating in the Coast Guard's Alternate Compliance Program are constructed and operated in accordance with classification society rules and are not required to meet all of the requirements in subpart 111.60. We are not aware of any casualties as a result of this.

We propose to add several additional cable construction standards to § 111.60-1, thus creating a broader list of acceptable standards. This has allowed us to propose removing many of the more prescriptive cable requirements in §§ 111.60-2, 111.60-3, 111.60-4, and 111.60-6 because of the availability of widely accepted additional standards. For example, cable for communication and radio frequency applications, and fiber optic cable, are available to meet the standards of § 111.60-1 and therefore §§ 111.60-2 and 111.60-6 are no longer necessary.

We also propose deleting the cable application regulations in § 111.60-3 as they are unnecessarily prescriptive. Instead, entities would consult the current and proposed cable construction standards in proposed § 111.60-1 for the application of specific types of cable. We propose to adopt these industry standards in lieu of our own prescriptive standards.

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 propose to 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. The existing and proposed 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 propose minor edits to make “bus-tie” and “feeder” plural where they appear in the table. As previously mentioned in the IBR updates to § 110.10-1, we would also update the NFPA NEC 2002 standard to its newer edition NFPA 70, where it appears in the table.

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

We propose to accept IEC 60092-502:1999 as an option for classification of hazardous locations (areas) in the new § 111.105-50(a). Section 111.105-50(a) would contain alternative standards 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 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 Alternate Compliance Program 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.”

2

The Coast Guard developed these supplemental requirements to ensure an equivalent level of safety as the requirements of subpart 111.105. In this rulemaking, we propose to 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 propose it as an option for U.S. vessels.

In § 111.105-50(c), we propose to add 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 would 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.

E. Emergency Generator in Port

We propose in the new § 112.05-7 to allow the emergency generator to be used in port, provided supplemental safety standards are in place. The current regulations in § 112.05-1 requires 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, the International Association of Classification Societies 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. Predicated on the premise that this proposal provided an equivalent level of safety, it was subsequently adopted by the IMO in 2005, promulgated in IMO circular MSC/Circ.1176 dated 25 May 2005 and updated in IMO circular MSC.1/Circ. 1464/Rev.1 dated 24 Oct. 2013. Since then, most classification societies and flag States have harmonized their rules to align with this interpretation.

Similar to the determination made by the IMO, we propose to 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 proposed arrangements will result in improved performance, better fuel economy, lower emissions, and higher reliability than less integrated systems.

For these reasons, we propose to allow the emergency generator to be used in port provided that supplemental safety standards are in place. The supplemental safety standards proposed 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 Proposed Changes Within Subchapter J

Section 110.15-1 Definitions

We propose 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 would be moved from § 111.10-1(a) to § 110.15-1 so all definitions are in one location.

Section 110.25-1 Plans and Information Required for New Construction.

We propose to consolidate the hazardous locations plan submittal requirements of the existing § 110.25-1(i), (p), and (q) into a single section. 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 propose to 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.

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

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

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

The note to § 111.10-9 has been revised to clarify that transformers located downstream of the ship's service switchboard are not required to be provided in duplicate. This is an item regularly misunderstood and is explained on page 16 of the Navigation and Vessel Inspection Circular (NVIC) 2-89, “Guide for Electrical Installations on Merchant Vessels and Mobile Offshore Drilling Units”, dated Aug. 14, 1989.

https://www.dco.uscg.mil/Portals/9/DCO%20Documents/5p/5ps/NVIC/1989/n2-89.pdf.

Section 111.12-11 Generator Protection

In this section and many other sections, the term “semiconductor rectifier (SCR)” has been replaced with “semiconductor converter”, a term now more commonly used in industry.

Section 111.12-13 Propulsion Generator Protection

This section on propulsion generator protection would be deleted because it is simply a reference to § 111.35-1. This cross reference is not necessary.

Section 111.15-10 Ventilation

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

Section 111.25-5 Marking

We propose to delete this section because the requirements for motor markings are sufficiently addressed by the referenced ABS Marine Vessel Rules.

Section 111.30 Switchboards

The requirements for switchboards contained in IEEE 45 2002 would be replaced with requirements from the recently published IEEE 45.7 (2012).

This proposed rule would add a note to § 111.30-5 warning that the interchangeability and compatibility of components complying with both IEEE and IEC cannot be assumed, to address the growing use of components meeting IEC standards on U.S. vessels.

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

The term “pilot light” would be replaced with the more commonly used term “indicator light.”

Subpart 111.33 Power Semiconductor Rectifier Systems

The requirements for semiconductor converters contained in IEEE 45 2002 are being replaced with requirements from the recently published of IEEE 45.2 (2012).

Section 111.50-3 Protection of Conductors

In § 111.50-3(b)(2), the requirements for steering gear circuits is being changed from subchapter F to a more specific cite of § 58.25. Reference to IEC 92-202 has been removed 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

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

NAVSEA DDS 300-2 is proposed for deletion because it is no longer available. IEC 61660-1:1997 would be added as a standard for DC systems.

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

Section 111.54-1 Circuit Breakers

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

Section 111.75-17 Navigation Lights

In § 111.75-17(a), we propose to remove the requirement that the navigation light indicator panel be supplied by a feeder directly from the emergency switchboard. The panel will still be required to be supplied from the

emergency switchboard but this change allows for the common practice of suppling 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 are also proposing to delete § 112.43-13 which provided details on the navigation light panel feeder.

In § 111.75-17(d)(2), we propose to offer EN 14744 as an alternative for certification of navigation lights. UL 1104 is the other acceptable standard, but it has not been updated in over 20 years and addresses neither LED light sources nor EMC testing. The other construction and testing requirements of EN 14744 are not identical to UL 1104, but it is accepted worldwide. It addresses LED lights and EMC testing and has been published for 15 years. 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. Navigation lights constructed and tested to the requirements of EN 14744 have been accepted by the Coast Guard on a case-by-case basis subject to the additional requirements of the USCG Marine Safety Center's Marine Technical Note 01-18, Guidance for Establishing Equivalency to UL 1104 Navigation Lights.

4

We propose to accept EN 14744 without these additional requirements.

4

See https://www.dco.uscg.mil/Portals/9/MSC/MTN/MTN.01-18.07.16.18.LEDandEUNavigationLights.pdf.

Additionally in § 111.75-17(d)(2), the requirements for battery powered navigation lights have been clarified. The existing text has been misinterpreted on occasion. These lights must be certified by an independent laboratory to the applicable requirements of UL 1104 or EN 14744, as must all navigation lights. This ensures they meet the applicable requirements of the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS) and the Inland Navigation Rules (33 CFR 83).

We propose deleting the requirements for a flashing light in the existing § 111.75-17(d)(4), because these requirements are contained in section 22.11 of UL 1104 and section 4.4 of EN 14744.

Section 111.75-18 Signaling Lights

We propose deleting the outdated, prescriptive requirements on signaling lights in this section that were based on the applicable international requirements in 1996 and incorporating 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.

Section 111.75-20 Luminaires (Lighting Fixtures)

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

Section 111.83-7 High Voltage Shore Connection

We propose adding in this new section a standard for high voltage shore connection systems, IEC/IEEE 80005-1:2019, applicable to ships required by state or local law to 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 high voltage shore connections. This standard is offered as an option for compliance with state or local law.

Section 111.99-3 Definitions

We propose removing this section of definitions. Fire door holding and release systems, if fitted, must meet SOLAS II-2/9.4.1.1.5.3. This reference has been updated based on the reorganization of SOLAS Chapter II-2. These definitions are no longer necessary.

Section 111.103 Remote Stopping Systems

The wording of 46 CFR 111.103 has caused confusion due to the order of the subsection with readers inferring that machinery space ventilation is a separate category from the ventilation referred to by 46 CFR 111.103-7. We propose editorial changes to this section to clarify its intent.

Subpart 111.105 Hazardous Locations

The Coast Guard has 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 propose to revise subpart 111.105 (Hazardous Locations) to be consistent with these two sets of regulations. This would expand the list of acceptable national and international explosion protection standards, providing more options for operators.

We propose adding 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 Outer Continental Shelf (OCS) facilities, vessels other than Offshore Supply Vessels (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 propose incorporating these standards so that they are available to all vessels and facilities that must comply with subchapter J.

In § 111.105-17(a)(1)(i), we propose adding three new standards for equipment in hazardous locations, UL 783, ANSI/ISA 12.12.01, and ANSI/UL 2062. See section VI.A for further explanation of each standard.

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

In the new § 111.105-28, we propose adding ASTM F2876-10 to address internal combustion engines in hazardous locations. Under the proposed section, internal combustion engines installed in Class I Divisions 1 and 2 would be required to 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 would 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 propose 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 the existing §§ 111.106-3(f) and 111.108-3(f).

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

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

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

In § 111.105-41, we propose removing 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 propose to add three new standards for equipment in hazardous locations, UL 783, ANSI/ISA 12.12.01, and ANSI/UL 2062. See section VI.A for further explanation of each standard.

Section 111.107-1 Industrial Systems

In § 111.107-1(b), we propose to clarify the standards for switchgear. Currently § 111.107-1(b)(1) refers to an unnecessarily broad range of standards. We propose to 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 propose to remove paragraph (b) from § 111.108-1. Paragraph (b) of this section is 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 would no longer be necessary because we propose to include the same standards and systems in § 111.108-3 (General requirements).

In § 111.108-3(b)(1)(i), we are adding three new standards for equipment in hazardous locations: UL 783, ANSI/ISA 12.12.01, and ANSI/UL 2062. See section VI.A for further explanation of each standard.

Section 112.01-20 Final Emergency Power Source

We propose to clarify the description of the final emergency power source. For the convenience of the reader, we also propose cross-referencing § 112.15-5, which specifies the existing regulations for final emergency power sources.

Section 112.05-5 Emergency Power Source

In § 112.05-5(a), we are clarifying that the emergency power source must be sized using a unity (1.0) service factor on all loads 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%. 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 will be appropriately sized to accomplish this task.

Section 112.15-1 Temporary Emergency Loads

In § 112.15-1(s), we propose to 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.

Section 112.43-13 Navigation Light Indicator Panel Supply

We propose to delete this requirement because the navigation light indicator panel supply is proposed to no longer be required by § 111.75-1(a) to be directly supplied by a feeder from the emergency generator but can be supplied by an electrical panel, such as an emergency lighting panel, which is supplied by the emergency switchboard.

Section 112.50-1 General

In § 112.50-1(g), we propose to delete the requirement that emergency generators automatically shut down upon loss of lubricating oil pressure. This section would 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 propose to reformat § 112.50-1(g) to clarify the remaining regulations for emergency generator set shut downs.

In addition, we propose to 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 nonsubstantive formatting edit that would not affect the existing alarm regulations for emergency generators in § 112.50-1(h).

VII. Incorporation by Reference

Material proposed for incorporation by reference appears in § 110.10-1, and is summarized and discussed in section VI.A of this preamble. Copies of the material are available from the sources listed in § 110.10-1, and we believe they are generally available to or already in use by the class of persons potentially affected by this proposed rule. The standards we are proposing to incorporate by reference are available either at the publisher's web address included in the proposed regulatory text of § 110.10-1 or by contacting the publisher listed in the standard. With this proposed rule, we also reviewed and updated all the publisher's web addresses listed in proposed § 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 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.

section for additional direction on how to obtain access to electronic copies of the materials. Before publishing a binding rule, we will submit this material to the Director of the Federal Register for approval of the incorporation by reference.

VIII. Regulatory Analyses

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

A. Regulatory Planning and Review

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

The Office of Management and Budget (OMB) has not designated this proposed rule a significant regulatory action under section 3(f) of Executive Order 12866. Accordingly, OMB has not reviewed this proposed rule. Details on the estimated cost savings of this rule can be found in the rule's regulatory analysis (RA) that follows.

The Coast Guard proposes to update subchapter J of title 46 of the CFR. This proposed rule would align the standards, which 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 that we reference in subchapter J. The provisions of this proposed rule would 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 would simply incorporate by reference the 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 proposed rule to generate cost savings to industry and the Federal Government of approximately $204,695 over a 5-year period of analysis in 2019 dollars, using a 7-percent discount rate (we are using a 5-year period of analysis because we anticipate this proposed rule would not produce cost savings beyond this time period). We estimate annualized cost savings to be approximately $49,923, using a 7-percent discount rate. The cost savings are a result of industry submitting fewer equivalency requests to the Coast Guard, which we base this cost savings analysis upon. We also expect the proposed rule to generate unquantified benefits because incorporating these standards would simplify regulatory compliance, reduce confusion, and provide industry flexibility. Table 2 provides a summary of the impacts of the proposed rule.

Summary

Applicability

Incorporate by reference (IBR) electrical engineering standards or update existing standards through IBR in subchapter J of Title 46 CFR.

Affected Population

• Cost savings based on an 80% reduction of equivalency requests from owners and operators of 210 new U.S.-flagged vessels that entered service over the past 5 years.

• Standards used by approximately 5,570 U.S.-flagged vessels (affected population varies by CFR part and subpart, see table 3).

Benefits

Cost Savings ($2019, 7-percent discount rate):

5-year period of analysis: $204,695.

Annualized: $49,923.

Provide flexibility by offering options or alternatives for IBR and non-IBR provisions; remove regulatory redundancy and confusion by updating standards and simplifying regulatory text through editorial changes.

Affected Population

There are numerous provisions of this proposed rule that affect 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.

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. Subchapter O contains tank barges and freight barges.

This proposed rule would affect approximately 5,570 existing, inspected U.S.-flagged vessels. We obtained the affected population of this proposed rule from our Marine Information for Safety and Law Enforcement (MISLE) database. For standards we are incorporating by reference in this proposed 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 last year. 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 and for vessels to meet the most recent incorporated standards when they enter service.

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 would generate cost savings by submitting fewer equivalency requests to the Coast Guard. Included in the total population of 5,570 vessels are 1,051 new U.S.-flagged vessels that entered service in the last 5 years, from 2014-2018. We divided 1,051 by 5 years to obtain an average of approximately 210 new U.S.-flagged vessels annually. See table 3 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 the past 18 months, or from September 2018 to February 2020. The number of equivalency requests the Coast Guard received from owners and operators of the 210 vessels during this period was 10 annually. Prior to this time period, the Coast Guard did not collect data on equivalency requests.

We expect this proposed rule would reduce the baseline number of equivalency requests the Coast Guard would receive from industry by 80 percent.

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 them for safety concerns in addition to maintaining pace with the technological advancements within the industry. Meaning, this proposed rule would reduce the number of equivalency requests by 80 percent annually. This in turn, would leave about 20 percent of the public who still may have questions about the standards they are using annually during the 5-year period. Alternatively stated, we do not expect this proposed rule or any updates to standards to eliminate the public's questions altogether. So we expect the number of equivalency requests that we receive from the public to be about 20 percent annually. The Coast Guard makes a determination in the year we receive a question (equivalency request) from the public; therefore, the questions would 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 proposed rule to reduce the number of questions by 80 percent in this year, which produces the cost savings. As a result, 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 proposed 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 standards organizations, again, create updates to existing standards.

6

Generally, standards get 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 remaining 80 percent (100 percent−20 percent) would generate the cost savings.

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. Equivalency requests are explained in greater detail in the Cost Savings Analysis portion of this analysis.
