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 Sec.  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 Sec.  56.10-5(c)(6). We have revised
the paragraph accordingly.
    One commenter suggested a minor rewording of Sec.  56.25-5, which
we have incorporated.
    One commenter asked us to remove the reference to threaded studs in
Sec.  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
Sec.  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 Sec.  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 Sec.  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 Sec.  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 Sec.  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 Sec.  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 Sec.
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 Sec.  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 Sec.
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 Sec.  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 Sec.  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 Sec.  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 Sec.  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 Sec.  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 Sec.  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
Sec.  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 Sec.  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 Sec.  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 Sec.  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
Sec.  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 Sec.  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 Sec.  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 Sec.  111.60-11(c), but without
apparent change. We have retained the NPRM language.
    Two commenters suggested deleting Sec.  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 Sec.  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 Sec. Sec.  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 Sec.  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 Sec.  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
Sec.  111.107-1. We have corrected the section so that it refers to
IEEE-1202.
    Finally, one commenter suggested adding references, in Sec.
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
ADDRESSES.

Sec.  54.10-5  Maximum allowable working pressure (reproduces UG-98).

    (a) The maximum allowable working pressure for a vessel is the
maximum pressure permissible at the top of the vessel in its normal
operating position at the designated coincident temperature specified
for that pressure. It is the least of the values found for maximum
allowable working pressure for any of the essential parts of the vessel
by the principles given in paragraph (b) of this section and adjusted
for any difference in static head that may exist between the part
considered and the top of the vessel. (See Appendix 3 of section VIII
of the ASME Boiler and Pressure Vessel Code (incorporated by reference;
see 46 CFR 54.01-1.)
    (b) The maximum allowable working pressure for a vessel part is the
maximum internal or external pressure, including the static head
hereon, as determined by the rules and formulas in section VIII of the
ASME Boiler and Pressure Vessel Code, together with the effect of any
combination of loadings listed in UG-22 of section VIII of the ASME
Boiler and Pressure Vessel Code (see 46 CFR 54.01-30) that are likely
to occur, or the designated coincident operating temperature, excluding
any metal thickness specified as corrosion allowance. (See UG-25 of
section VIII of the ASME Boiler and Pressure Vessel Code.)
    (c) Maximum allowable working pressure may be determined for more
than one designated operating temperature, using for each temperature
the applicable allowable stress value.

    Note: Table 54.10-5 gives pictorially the interrelation among
the various pressure levels pertinent to this part of the
regulations. It includes reference to section VIII of the ASME
Boiler and Pressure Vessel Code for definitions and explanations.

test pressure shall be at least equal to one and one-tenth (1.10) times
the maximum allowable working pressure to be stamped on the vessel
multiplied by the lowest ratio (for the materials of which the vessel
is constructed) of the stress value ``S'' for the test temperature of
the vessel to the stress value ``S'' for the design temperature (see
UG-21 of section VIII of the ASME Boiler and Pressure Vessel Code
(incorporated by reference; see 46 CFR 54.01-1)). In no case shall the
