SUPPLEMENTARY INFORMATION:

Regulatory History

On February 8, 2000, we published a notice of proposed rulemaking (NPRM) entitled ``Marine Shipboard Electrical Cable Standards'' in the Federal Register (65 FR 6111). Following publication of the NPRM, we received several requests to hold a public meeting. In response to these requests, we scheduled a public meeting for June 28, 2000. We notified the public of the meeting in a notice of public meeting and reopening of comment period published on June 5, 2000 (65 FR 35600). On June 26, 2000, we published a correction to the notice (65 FR 39334). On July 27, 2000, we published a notice to reopen the comment period (65 FR 46143).

Background and Purpose

Since the last revision of our electrical engineering regulations in 46 CFR chapter I, subchapter J, (62 FR 23894, May 1, 1997), we have received a number of letters concerning the construction requirements in 46 CFR 111.60-1 and 111.60-3 for cable used on merchant vessels. Sections 111.60-1 and 111.60-3 allow the use of cables meeting certain industry standards listed in those sections. The letters suggest that there are other cable standards beside those listed in the two sections that would provide a level of performance and safety equivalent to the listed standards. The Coast Guard completed equivalency determinations on UL 1309 (1995); IEC 92-350, 1988, amendment 1 (1994); and IEC 92-353 (1995-01) and found them to be equivalent.

Discussion of Comments and Changes

The Coast Guard received 58 comments on the notice of proposed rulemaking (NPRM). Here, we discuss first comments of a general nature, then comments relating to specific sections of the regulation.

1. General Comments

   1. Several commenters liked the proposed changes to Secs. 111.60-1 and 111.60-3. They agreed that the changes offered the entire maritime industry more flexibility and increased the clarity of the regulations without compromising performance or safety. A number of comments commended the Coast Guard's effort to enhance its marine shipboard electrical cable regulation and incorporate industry standards, both domestic and international.

   2. Eight comments recommended that the Coast Guard use the new IEC numbering system for its references to any IEC standard.

      The Coast Guard agrees with these comments and will change them throughout 46 CFR as part of a separate rulemaking.

   3. Six comments stated that the Coast Guard requires marine shipboard electrical cable to be certified by an independent laboratory.

      The Coast Guard does not require third-party verification for marine shipboard electrical cable. The cable manufacturer may self- certify its cable

      [[Page 29909]]

      to any of the cable standards listed in Sec. 111.60-1(a).

   4. Three comments suggested that the Coast Guard list in 46 CFR all cable types approved by the Coast Guard as meeting a particular standard.

      If the cable meets a standard accepted by the Coast Guard, the standard's number (e.g., IEC 92-3) appears on the cable markings. Therefore, there is no need to also list them in the regulations.

   5. Several comments recommended that the edition of IEEE Std 45 referenced in the existing regulations be changed from the 1983 edition to the 1998 edition.

      As a separate project, we published a request for comments on January 8, 2001 (66 FR 1283), regarding this specific recommendation, and we look forward to receiving additional comments on this topic under that notice.

   6. Eleven comments stated that IEC 92-3 was an obsolete standard and should not be referenced in 46 CFR chapter I, subchapter J.

      The Coast Guard still recognizes IEC 92-3 as an acceptable standard, however it will be reviewed as part of a future rulemaking.

   7. Two comments asked whether NVIC 2-89, Guide for Electrical Installation on Merchant Vessels and Mobile Offshore Drilling Units, will still be valid with the incorporation of UL 1309 in Secs. 111.60-1 and 111.60-3.

      NVIC 2-89 is not affected by this rulemaking.

2. Comments on Specific Sections

   Section 111.60-1

   1. Six comments agreed with adding IEC 92-350 and IEC 92-353 to Secs. 111.60-1(a) and 111.60-3. These comments agree that the current marine shipboard cable regulations create an unwarranted differential between domestic rules and international standards. Some comments also pointed out that classification societies, such as American Bureau of Shipping (ABS) and Det Norske Veritas (DNV), accept IEC standards in their regulations.

   2. Three comments recommended that IEC 92-350 not be added to Sec. 111.60-1(a), as proposed, because IEC 92-353, which is also added to Sec. 111.60-1(a), refers to IEC 92-350.

      Although IEC 92-350 is referred to in IEC 92-353, the Coast Guard accepts only the 1988, amendment 1 (1994), edition of IEC 92-350. Therefore, IEC 92-350 is listed here and in Sec. 110.10-1(b) to let the user know which revision of the standard we recognize.

   3. Seven comments disagreed with adding IEC 92-350 and IEC 92-353 to Secs. 111.60-1 and 111.60-3. The reason most stated for this disagreement was that the thickness of the insulation of the IEC cable is less than the thickness of cable insulation under IEEE Std 45, 1983.

      We agree that the IEC cable does have thinner insulation and, because of this, we require the use of the derated ampacity and temperature table in IEC 92-352 for this cable. We have added this requirement for all cable constructed to IEC 93-353 and have added ``IEC 92-353'' to Secs. 111.60-3(c).

   4. Fourteen comments commended the Coast Guard's initiative in adding UL Std 1309 (1995) to Secs. 111.60-1(a) and 111.60-3(a).

   5. Five comments stated that cable constructed to UL 1309 provides for third-party testing of the cable. UL Std 1309 (1995), in itself, does not require or guarantee third-party testing (listing by UL). It is a construction standard to which a manufacturer may self-certify its cable. The manufacturer may then label the cable as meeting UL Std 1309 (1995), section 5(f). Third-party verification would be initiated if the cable manufacturer requests that the testing of the cable to UL Std 1309 (1995) be performed by an independent laboratory.

   6. Three comments recommended that UL Std 1309 (1995) not be used in the electrical cable regulations, because they believe the standard is not an industry consensus standard.

      UL standards are widely recognized throughout the maritime industry on an international level.

   7. Six comments requested that the Coast Guard identify only one standard in Sec. 111.60-1(a) and (b) for the flammability requirements for marine shipboard electrical cable.

      The current flammability standards are equivalent to one another. This allows manufacturers the flexibility to test their cables to one of the flammability standards in Sec. 111.60-1(a) or (b).

   8. Two comments stated that the low smoke zero halogen cable referred to in IEC 92-353 could not meet the flammability standards in IEC 332-3, as required by Sec. 111.60-1(b).

      In response to these comments, all cable must meet the flammability requirements of Sec. 111.60-1(a) or (b).

   9. Three commenters were concerned that the temperature ratings for Type T/N cable would be changed.

      Before this rulemaking, the Coast Guard accepted, based on an equivalency determination, Type T/N cable that carried a rating of 75 deg.C or 90 deg.C. Both of these ratings for Type T/N cable are listed in UL 1309. Therefore, ratings for these cables are not affected by this rulemaking.

   10. Two comments noted that, though we now allow, in Sec. 111.60- 1(a), the use of cable meeting UL Std 1309 or IEC 92-350, we do not have installation requirements for those cables.

       Section 111.60-5(a) states that each cable installation must meet (1) IEEE Std 45 sections 20 (except 20.11) and 22; or (2) IEC 92-3 and paragraph 8 of IEC 352. Section 111.60-3

   11. Six comments pointed out that Type T/N cable can not meet the application standards listed in UL Std 1309 (1995), as proposed in Sec. 111.60-3(b), because that standard is a construction and testing standard.

       We agree with these comments and will not make the proposed change to 46 CFR 111.60-3(b). For application purposes, Type T/N cable must meet the section 19 of IEEE Std 45, 1983, for Type T insulation.

       Incorporation by Reference

       The Director of the Federal Register has approved the material in Sec. 110.10-1(b) for incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51. Copies of the material are also available from the sources listed in that section.

       Regulatory Evaluation

       This rule is not a ``significant regulatory action'' under section 3(f) of Executive Order 12866 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. It is not ``significant'' under the regulatory policies and procedures of the Department of Transportation (DOT) (44 FR 11040, February 26, 1979). We expect the economic impact of this rule to be so minimal that a full Regulatory Evaluation under paragraph 10e of the regulatory policies and procedures of DOT is unnecessary.

       The rule is intended to provide a greater choice in the type of shipboard cable by allowing the use of cable made to standards other than those specified in the current regulations. This will increase the number of choices for vessel owners without increasing costs. In addition, it will benefit vessel owners by enhancing competition within the cable industry.

       We received three comments indicating that the proposed rule would significantly increase the cost of doing business for U.S. cable manufacturers. The comments expressed concern that foreign cable would be more cost

       [[Page 29910]]

       advantageous for shipyards and installers.

       This rule is intended to harmonize the Coast Guard's cable requirements with those of classification societies and international performance-based standards. It does not add additional requirements for U.S. cable manufacturers nor restrict them from also manufacturing cable to the newly added standards. The cable currently produced by U.S. manufacturers that meets the other standards listed in Secs. 111.60-1(a) (i.e., IEEE Std 45, IEC 92-3, MIL-C-24640A, or MIL-C- 24643A) will still be acceptable for shipboard use. Consequently, we disagree that this rule will increase the costs of doing business for U.S. cable manufacturers. However, this rule does add alternatives to the existing standards that will be accepted. End users will gain flexibility from having more purchasing options. If end users, such as small businesses, are able to save money from having additional options due to increased competition, the cost savings to them would be considered an economic benefit of this rulemaking.

       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.

       As discussed in the Regulatory Evaluation section of this preamble, there are no costs associated with this rule. Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this final rule will not have a significant economic impact on a substantial number of small entities.

       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).

       Federalism Summary Impact Statement

       We have analyzed this rule under Executive Order 13132, Federalism. This rule amends the regulations on vessel design and construction. In particular, it provides vessel owners with additional options in the choice of cable used on their vessels.

       It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled that all of the categories covered in 46 U.S.C. 3306, 3703(a), 7101, and 8101 (design, construction, alteration, repair, maintenance, operation, equipping, personnel qualification, and manning of vessels), as well as casualty reporting and other categories where Congress has intended the Coast Guard to be the sole source of a vessel's obligations, are within the field foreclosed from State regulation. (See the decision of the Supreme Court in the consolidated cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 120 S. Ct. 1135 (March 6, 2000).)

       This entire rule falls into the field encompassed by 46 USC 3306 and 3703(a), where, by operation of law, State regulation is precluded. For this reason, consultation under section 6 of the Executive Order would not be meaningful and, therefore, is unnecessary.

       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.

       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.

       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.

       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 does not concern an environmental risk to health or risk to safety that may disproportionately affect children.

       Indian Tribal Governments

       This rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments. Rules with tribal implications have substantial direct effects 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.

       Environment

       We have considered the environmental impact of this rule and concluded that, under figure 2-1, paragraphs (34)(d) and (e), of Commandant Instruction M16475.1C, this rule is categorically excluded from further environmental documentation. This rule concerns the equipping of, and carriage requirements for, vessels. A ``Categorical Exclusion Determination'' is available in the docket where indicated under ADDRESSES.
