II. Regulatory History

On June 30, 2004, we published a notice of proposed rulemaking (NPRM) entitled “Review and Update of Standards for Marine Equipment” in the

Federal Register

(69 FR 39742). We received 13 letters commenting on the proposed rule. Two commenters suggested we hold a public meeting to discuss changes they recommended. However, as those recommendations are beyond the scope of this rulemaking, we did not adopt this suggestion and no public meeting was held.

In numerous cases, the exact designation of standards that we incorporate by reference has changed between the NPRM and this final rule. These changes have been made to bring our regulatory text into compliance with Office of the Federal Register technical requirements governing incorporations by reference, and are intended to help the public better identify exactly which standards we intend to enforce. They are not intended to be substantive changes and receive no further discussion.

Other changes are relatively few in number and may or may not be substantive. They are discussed in “IV. Discussion of Comments and Changes.” Overall, the changes we have made since publishing the NPRM are either non-substantive or are the logical outgrowth of the NPRM. A supplemental notice of proposed rulemaking (SNPRM) is, therefore, unnecessary, and would delay completion of this rulemaking. Thus, we find good cause under 5 U.S.C. 552(b)(B) to proceed with publication of this final rule without an SNPRM.

III. Background and Purpose

The Coast Guard has actively participated in the development of industry standards of safety for marine equipment at the International Maritime Organization (IMO), the International Organization for Standardization (ISO), the ASTM International, and other standards-setting bodies that belong to the American National Standards Institute (ANSI).

This rule is part of an ongoing effort for regulatory review and reform, with the goals of: (1) Updating references to incorporated standards that have been modified; (2) removing obsolete rules; (3) making our regulations performance-based; and (4) expanding efforts to promote consensual rulemaking.

IV. Discussion of Comments and Changes

The NPRM discusses the changes made by this rule in detail. In general, our changes fall into eight categories:

(1) Revisions to authority citations.

(2) Correction of prior inadvertent errors or deletions.

(3) Deletion of obsolete or superfluous material.

(4) Adoption of The International System of Units (metric) measurements.

(5) Reduction of regulatory thresholds.

(6) Stylistic revisions.

(7) Updating cross references.

(8) Updating references to industry standards.

This rule affects only inspected commercial vessels. It imposes no new requirements and, therefore, requires no phase-in period.

The Coast Guard received 13 letters commenting on the NPRM. Many of the comments suggested changes that go beyond the scope of this rulemaking, including the adoption of newer industry standards. This rulemaking is designed to update references to industry standards, but is not intended to introduce new standards that would change the substance of our regulations. We have not adopted any of these suggestions and, in most cases, do not discuss their merits in this document. Nevertheless, we appreciate these comments and may consider them in the future, should we ever undertake a more substantive revision of our rules.

Four commenters stated that two major documents developed by the American Petroleum Institute (API), API RP-14F and API RP-14FZ, were not recognized when creating these rules and merit consideration. We did not consider this recommendation because it is beyond the scope of this rulemaking.

Two commenters strongly recommended that the Coast Guard hold a public meeting to identify cable designs, their functional attributes, and their ultimate recognition as acceptable designs for the marine industry. As previously discussed, these suggestions are beyond the scope of this rulemaking and we did not adopt this recommendation.

One commenter stated that, because this rulemaking is applicable to low voltage power control and medium voltage insulated conductor constructions, the optional insulation systems and armor designs available for these cables should be discussed during this revision cycle to serve the purpose of updating and including state-of-the-art technology. This is beyond the scope of this rulemaking, but we point out that new state-of-the-art technologies can be submitted for equivalency review.

One commenter stated that the name of ASTM (American Society for Testing and Materials) has changed to American Standards for Testing and Materials (ASTM) International. The actual name is now ASTM International, and we have changed the text accordingly.

One commenter suggested that we review the wording of § 56.10-1(b). We have reworded the paragraph to incorporate what we believe to be the commenter's concern.

One commenter suggested that we incorporate a reference to “similar junction equipment” in § 56.10-5(c)(6). We have revised the paragraph accordingly.

One commenter suggested a minor rewording of § 56.25-5, which we have incorporated.

One commenter asked us to remove the reference to threaded studs in § 56.25-20(d), saying that a stud is an unthreaded pin used in guiding the application. We disagree and have retained the language used in the NPRM. Studs have threads similar to bolts, but have no heads.

One commenter asked us to make minor revisions to the wording of § 56.25-20(e). Because our intention is to reproduce ASME-B31.1, part 108.5.1, we decline this request and have retained the language of the NPRM.

One commenter asked us to replace, in § 56.30-20(d), the phrase “No pipe * * *” with “No steel pipe * * *.” We do not think this change is necessary, but have revised the language in the NPRM to omit a reference to ANSI standard weight.

One commenter requested minor revisions to § 56.60-3(b). Because our intention is to reproduce ASME-B31.1 part 124.2.C, we decline this request and have retained the language of the NPRM.

One commenter asked us to revise the language of § 92.15-10(d). The commenter's proposed revision was identical to the text in the NPRM. However, we have revised the paragraph to include a reference to 46 CFR 97.80-1.

Three commenters requested that in § 110.10-1, we replace the reference to IEEE Std 45-1998 with a reference to a newer standard, IEEE Std 45-2002. A fourth commenter asked us to add several International Electrotechnical Commission (IEC) standards to this section. These changes are outside the scope of the rulemaking. Note that in some cases, the additional standards these commenters suggest need not be made explicit in the regulatory text; compliance with those standards is already required by the standards that we do list.

One commenter asked us to amend § 111.01-9 to make it clear that there is no exact correlation between NEMA types and IEC IP types. We have retained the NPRM version of this section, which does not correlate the NEMA and IEC types, but provides the minimum NEMA and IEC IP protection required. The rule provides two separate, independent schemes for achieving protection. The user will follow either NEMA or IEC IP types.

Three commenters requested that we change the title of § 111.05-7 and substitute “All cables shall be installed in accordance with requirements of section 25 of IEEE 45-2002” for the NPRM text, because the section should apply not only to armored cable but to all cable, thus providing the total installation requirements. We did not accept this recommendation because it is outside the scope of this rulemaking.

Four commenters pointed out that the reference in § 111.30-19(a)(1) to “Section 7.10” is to IEEE 45-1998, not the newer IEEE 45-2002 revision. They asked us to incorporate the 2002 standards in order to provide a higher level of safety. This recommendation is outside the scope of this rulemaking.

One commenter asked us to change the minimum cable size in § 111.30-19(b)(3) from 14 AWG to 15 AWG, to be on par with IEC. This recommendation is outside the scope of this rulemaking.

Three commenters suggested that the inclusion of § 111.60-1(c) as it appeared in the NPRM is redundant, because T/N cable construction is covered in IEEE 1580, which is referred to in paragraph (a) of the section. We agree and have deleted the NPRM language of paragraph (c).

Three commenters pointed out that § 111.60-1(d), as it appeared in the NPRM, incorrectly referenced IEEE Std 45, which does not provide cable construction data. We agree that the correct reference is to IEEE 1580 and have revised this paragraph accordingly.

One commenter asked us to amend § 111.60-2 to require the use of continuous corrugated metal clad armor or installation within continuous metal piping. This recommendation is outside the scope of this rulemaking.

One commenter stated that, in § 111.60-2, the reference to IEC 60332-2 is incorrect and should be changed to IEC 60332-3-23. We agree that the reference in the NPRM is incorrect, but have corrected the reference to read IEC 60332-3-22. The same commenter also asked us to delete the reference in this section to ANSI/UL 1581 test VW-1, on the grounds that it is inferior to the other listed standards in evaluating flame propagation behavior of completed cable assemblies. This recommendation is outside the scope of this rulemaking.

Two commenters asked us to amend § 111.60-3 so that all cable to be installed as marine shipboard cable must meet the performance requirements in Table 24 of IEEE 45. We have retained the NPRM language. Table 24 of IEEE Std 45-2002 is meant for

cable application, not cable performance requirements. Table 24 of IEEE Std 45-2002 does not apply in whole to each cable construction standard recognized in § 111.60-1 of this subpart and is not applicable to this section.

Three commenters asked us to replace the NPRM's “must meet” in § 111.60-3(a)(3) with “must be applied in accordance with,” for better clarity as to the correct ampacity. We agree and have changed the language accordingly.

Three commenters asked us to replace the NPRM's “be derated according to” in § 111.60-3(b)(1) with “be applied in accordance with.” We agree and have changed that language accordingly. However, we disagree with their additional comment that the reference in paragraph (b)(1) to Note 6 should be deleted because it requires no additional derating. We have retained the reference as Note 6 provides for additional derating of cables when the cable is double banked.

One commenter suggested the use of “clause” instead of “paragraph” in § 111.60-3(b)(2) to conform to IEC usage. We have made the requested change here and throughout subpart 111.60.

Three commenters asked us to remove the exception in § 111.60-5(a)(1) for section 25.11 of IEEE Std 45, saying the exception is not justified technically and that its removal would be consistent with § 111.60-19. We have retained the exception. Section 111.60-19 explicitly states one area where cable splicing is allowed and is only applicable to hazardous locations; splicing is only allowed in intrinsically safe locations. These locations, by definition, are low voltage applications.

Three commenters asked us to broaden § 111.60-5(a)(2) so that it refers to all of IEC 60092-352, not just to clause 8 of that standard, because proper installation requires use of the entire standard. We agree and have changed the text accordingly.

Two commenters asked us to revise § 111.60-5(c)(3) to permit the use of certain types of metal sheath as a grounding conductor. We have retained the NPRM language. The Coast Guard has a longstanding policy of not allowing any cable armor to be used as a grounding conductor. The requested change is a significant modification to our rules and is, therefore, beyond the scope of this rulemaking.

One commenter asked us to revise § 111.60-11(c), but without apparent change. We have retained the NPRM language.

Two commenters suggested deleting § 111.60-23 because its subject is addressed by IEEE 1580. Alternatively, they suggested revising the section “to correct the construction and installation.” We have retained the section as it appears in the NPRM. The requested change is beyond the scope of this rulemaking. Also, the restrictions of 46 CFR 111.60-23(c) cover a broader range of potential motions than those addressed in IEEE-1580, clauses 5.17.13 and 5.17.14. A detailed review of this issue is discussed in the

Federal Register

publications of June 4, 1996, page 28265, and May 1, 1997, page 23901. Prior to the publication of the existing rule, the Coast Guard conducted a complete review and revision of the regulations, bolstered by onsite observations, in order to determine the safe application of type MC cable aboard a vessel.

One commenter asked us to revise § 111.60-23(b) to require continuous corrugation, and to make other wording changes. We have retained the NPRM language. Continuous corrugation is already required by paragraph (a) of this section.

One commenter implied that we should omit §§ 111.105-3, 111.105-31(e), and 111.105-41 because their content is covered by section 33 of IEEE Std 45-2002. We are retaining these provisions. Adoption of the 2002 standard would, in these cases, constitute substantive changes beyond the scope of this rulemaking.

Three commenters asked us to revise § 111.105-17(a) to permit the use of Type MC-HL cable. This recommendation is outside the scope of this rulemaking.

Three commenters asked us to revise § 111.105-41 so that it specifically references clauses 22.7.2 and 33.7.3 of IEEE 45. We are retaining the current general reference to IEEE 45 because several of its clauses are applicable.

One commenter called our attention to an incorrect reference in § 111.107-1. We have corrected the section so that it refers to IEEE-1202.

Finally, one commenter suggested adding references, in § 113.30-25(j)(2), to IEC 60331-23 and IEC 60331-25. We are retaining the NPRM language for paragraph (j)(2). The recommendation is outside the scope of this rulemaking.

V. Incorporation by Reference

The Director of the Federal Register has approved the material in 46 CFR 52.01-1, 53.01-1, 54.01-1, 56.01-2, 58.03-1, 59.01-2, 62.05-1, 63.05-1, 76.01-2, 92.01-2, 110.10-1, 162.017-1, 170.015, and 175.600 for incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51. Copies of the material are available from the sources listed in those sections.

VI. Regulatory Analyses

We developed this rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analyses based on 13 of these statutes or executive orders.

A. Regulatory Planning and Review

This rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. The Office of Management and Budget has not reviewed it under that Order. We expect the economic impact of this rule to be so minimal that a full Regulatory Assessment is unnecessary.

We received 13 letters commenting on the NPRM. None of these letters suggested there would be additional costs to industry for compliance with these revised industry standards.

Operators, owners, and manufacturers of vessels affected by this rule currently practice and adhere to national and international standards developed by organizations composed of representatives from a cross-section of interest groups affected by these standards.

We estimate that this final rule will have no additional costs to industry. New vessels coming into service are equipped and built under the provisions and standards of this rule.

These provisions and standards are not retroactive for owners and operators of existing vessels. Additionally, these owners and operators are not required to upgrade to the new standards if their equipment breaks down. Owners and operators of existing vessels have the option of repairing existing equipment or possibly installing similar equipment. These owners and operators may incur expected repair and replacement costs related to their existing equipment, but they will not incur additional mandatory costs associated with the provisions and requirements of this rule. If any owner or operator of an existing vessel of the current fleet chooses to upgrade, it is a voluntary upgrade.

B. Benefits

This rule will eliminate confusion caused by outdated and conflicting rules on the safety of marine engineering for owners, operators, and manufacturers of vessels. These changes will update outdated rules to meet current national and international standards. In addition, this rule will give the maritime industry clear instructions and descriptions of how to comply with various rules.

C. Small Entities

Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we considered whether this rule will 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.

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 because it is not retroactive and because it imposes no mandatory costs on owners or operators of vessels.

D. Collection of Information

This rule calls for no new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520).

E. Federalism

A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on State or local governments and would either preempt State law or impose a substantial direct cost of compliance on them. We have analyzed this rule under that Order and have determined that it does not have implications for federalism. This rule will revise outdated standards on safety of marine equipment with international and national standards created and approved in part by State and local governments that participate in organizations that develop national standards for marine operation and safety.

F. Unfunded Mandates Reform Act

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

G. Taking of Private Property

This rule will not effect 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 may 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 does 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. The Administrator of the Office of Information and Regulatory Affairs has not designated it as a significant energy action. Therefore, it does not require a Statement of Energy Effects under Executive Order 13211.

L. Technical Standards

The National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note) directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through the Office of Management and Budget, with an explanation of why using these standards would be inconsistent with applicable law or otherwise be 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.

This rule uses voluntary consensus standards from the following organizations: American Bureau of Shipping (ABS) International, American National Standards Institute (ANSI), American Petroleum Institute (API), American Society of Mechanical Engineers (ASME), American Gas Association, ASTM International, International Electrotechnical Commission (IEC), Institute of Electrical and Electronic Engineers (IEEE), International Maritime Organization (IMO), Instrument Society of America (ISA), International Organization for Standardization (ISO), Manufacturers Standardization Society of the Valve and Fitting Industry, Inc. (MSS), Naval Sea Systems Command (NAVSEA), National Electrical Manufacturers Association (NEMA), National Fire Protection Association (NFPA), Naval Publications and Forms Center (NPFC), Society of Automotive Engineers (SAE), and Underwriters' Laboratories, Inc. (UL). The sections that reference these consensus standards and the locations where these standards are available are listed in 46 CFR 52.01-1, 53.01-1, 54.01-1, 56.01-2, 58.03-1, 59.01-2, 62.05-1, 63.05-1, 76.01-2, 92.01-2, 110.10-1, 162.017-1, 170.015, and 175.600.

M. Environment

We have analyzed this rule under Department of Homeland Security Management Directive 5100.1 and Commandant Instruction M16475.lD, which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have concluded under the Instruction that there are no factors in this case that would limit the use of a categorical exclusion under section 2.B.2 of the Instruction. Therefore, this rule is categorically excluded, under figure 2-1, paragraph (34)(d) of the Instruction, from further environmental documentation. This rule will replace outdated safety standards for marine equipment with current national and international standards, and therefore will not have any impact on the environment. An environmental analysis checklist and a categorical exclusion determination are available in the docket where indicated under

Figure 56.30-10(b), Method 2

. ASME B16.5 (incorporated by reference; see 46 CFR 56.01-2) Class 150 and Class 300 low-hubbed flanges with screw threads, plus the addition of a strength fillet weld of the size as shown, may be used in Class I systems not exceeding 750 °F or 4 NPS, in Class II systems without diameter limitations, and in Class II-L systems not exceeding 1 NPS. If 100 percent radiography is required by § 56.95-10 of this part for the class, diameter, wall thickness, and material of pipe being joined, the use of the threaded flanges is not permitted and buttwelding flanges must be provided. For Class II piping systems, the size of the strength fillet may be limited to a maximum of 0.525 inch instead of 1.4T.

(3)

Figure 56.30-10(b), Method 3

. Slip-on flanges meeting ASME B16.5 may be used in piping systems of Class I, Class II, or Class II-L not to exceed the service pressure-temperature ratings for flanges of class 300 and lower, within the temperature limitations of the material selected for use, and not to exceed 4-inch Nominal Pipe Size (NPS) in systems of Class I and Class II-L. If 100-percent radiography is required by 46 CFR 56.95-10 for the class, diameter, wall thickness, and material of the pipe being joined, then slip-on flanges are not permitted and buttwelding flanges are required. The configuration in Figure 127.4.4B(b) of ASME B31.1 (incorporated by reference; see 46 CFR 56.01-2), using a face and backweld, may be preferable where eliminating void spaces is desirable. For systems of Class II, the size of the strength fillet may be limited to a maximum of 0.525 inch instead of 1.4T, and the distance from the face of the flange to the end of the pipe may be a maximum of three-eighths of an inch. Restrictions on the use of slip-on flanges appear in § 56.50-105 of this part for low-temperature piping systems.

) All threads on piping components must be taper pipe threads in accordance with the applicable standard listed in 46 CFR 56.60-1, Table 56.60-1(b). Threads other than taper pipe threads may be used for piping components where tightness of the joint depends on a seal weld or a seating surface other than the threads, and where experience or test has demonstrated that such threads are suitable.

(d) No pipe with a wall thickness less than that of standard weight of ASME B36.10M (incorporated by reference; see 46 CFR 56.01-2) steel pipe may be threaded regardless of service. For restrictions on the use of pipe in steam service more than 250 pounds per square inch or water service over 100 pounds per square inch and 200 °F (938C), see part 104.1.2(c)(1) of ASME B31.1 (incorporated by reference; see 46 CFR 56.01-2). Restrictions on the use of threaded joints apply for low-temperature piping and must be checked when designing for these systems.

Table 56.60-1(a) replaces Table 126.1 in ASME B31.1 and sets forth specifications of pipes, tubing, and fittings intended for use in piping-systems. The first column lists acceptable standards from ASTM (all incorporated by reference; see 46 CFR 56.01-2); the second lists those from ASME (all incorporated by reference; see 46 CFR 56.01-2). The Coast Guard will consider use of alternative pipes, tubing, and fittings when it receives certification of their mechanical properties. Without this certification it will restrict use of such alternatives to piping-systems inside heat exchangers that ensure containment of the material inside pressure shells.

127. Amend § 56.60-25 by revising paragraph (a) introductory text, paragraphs (b)(1), (b)(2), (b)(3), and (b)(5), and by adding paragraph (b)(6) to read as follows:

§ 56.60-25

Nonmetallic materials.

(a) Plastic pipe installations shall be in accordance with IMO Resolution A.753(18) (incorporated by reference; see 46 CFR 56.01-2) and the following supplemental requirements:

(b)

Nonmetallic flexible hose

. (1) Nonmetallic flexible hose must be in accordance with SAE J1942 (incorporated by reference; see 46 CFR 56.01-2) and may be installed only in vital and nonvital fresh and salt water systems, nonvital pneumatic systems, lube oil and fuel systems, and fluid power systems.

(2) Nonmetallic flexible hose may be used in vital fresh and salt water systems at a maximum service pressure of 1,034 kPa (150 psi). Nonmetallic flexible hose may be used in lengths not exceeding 76 cm (30 inches) where flexibility is required, subject to the limits in paragraphs (a)(1) through (4) of this section. Nonmetallic flexible hose may be used for plastic pipe in duplicate installations in accordance with this paragraph (b).

(3) Nonmetallic flexible hose may be used for plastic pipe in non-vital fresh and salt water systems and non-vital pneumatic systems, subject to the limits of paragraphs (a)(1) through (4) of this section. Unreinforced hoses are limited to a maximum service pressure of 345 kPa (50 psi); reinforced hoses are limited to a maximum service pressure of 1,034 kPa (150 psi).

(5) Nonmetallic flexible hose must be complete with factory-assembled end fittings requiring no further adjustment of the fittings on the hose, except that field attachable type fittings may be used. Hose end fittings must comply with SAE J1475 (incorporated by reference; see 46 CFR 56.01-2). Field attachable fittings must be installed following the manufacturer's recommended practice. If special

equipment is required, such as crimping machines, it must be of the type and design specified by the manufacturer. A hydrostatic test of each hose assembly must be conducted in accordance with § 56.97-5 of this part.

(6) The fire-test procedures of ISO 15540 (incorporated by reference; see 46 CFR 56.01-2) are an acceptable alternative to those procedures of SAE J1942. All other tests of SAE J1942 are still required.

128. Revise § 56.65-1 to read as follows:

§ 56.65-1

General (replaces 127 through 135).

The requirements for fabrication, assembly and erection in subparts 56.70 through 56.90 shall apply in lieu of 127 through 135.4 of ASME B31.1 (incorporated by reference; see 46 CFR 56.01-2). Those paragraphs reproduced are so noted.
