Electrical Engineering Requirements for Merchant Vessels

AGENCY: Coast Guard, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: As part of the President's Regulatory Reinvention Initiative, 
the Coast Guard is amending its electrical engineering regulations to 
reduce the regulatory burden on the marine industry, purge obsolete and 
out-of-date regulations, and eliminate requirements that create an 
unwarranted differential between domestic rules and international 
standards. This rulemaking harmonizes, where possible, the electrical 
engineering regulations with recent amendments to the International 
Convention for the Safety of Life at Sea, 1974, as amended. 
Additionally, this rulemaking dramatically revises certain prescriptive 
electrical equipment design, specification, and approval requirements 
and replaces them with performance-based requirements that incorporate 
international standards.

DATES: This final rule is effective June 16, 1997. The incorporation by 
reference of certain publications listed in the rule is approved by the 
Director of the Federal Register on June 16, 1997.

ADDRESSES: Documents as indicated in this preamble are available for 
inspection or copying at the office of the Executive Secretary, Marine 
Safety Council (G-LRA/3406), U.S. Coast Guard Headquarters, 2100 Second 
Street SW., room 3406, Washington, DC 20593-0001, between 9:30 a.m. and 
2 p.m., Monday through Friday, except Federal holidays. The telephone 
number is 202-267-1477.

SUPPLEMENTARY INFORMATION:

Regulatory History

    On February 2, 1996, the Coast Guard published a notice of proposed 
rulemaking (NPRM) entitled ``Electrical Engineering Requirements for 
Merchant Vessels'' in the Federal Register (61 FR 4132). There were two 
correction notices published for the NPRM on February 23, 1996 (61 FR 
7050), and March 5, 1996 (61 FR 8539). The Coast Guard received 45 
letters commenting on the proposal. As a result of requests from a 
national trade association, a notice was published on February 26, 1996 
(61 FR 7090), extending the comment period from March 18, 1996, to 
April 2, 1996, and announcing a public meeting on March 25, 1996. Over 
20 persons attended the meeting and 9 commented on the NPRM. A 
recording and summary of the meeting are in the rulemaking docket. On 
June 4, 1996, the Coast Guard published an interim rule in the Federal 
Register (61 FR 28260).
    Correction notices were published on June 26, 1996 (61 FR 33045), 
July 3, 1996 (61 FR 34927), July 11, 1996 (61 FR 36608), July 12, 1996 
(61 FR 36786), July 30, 1996 (61 FR 39695), and September 23, 1996 (61 
FR 49691), in the Federal Register. Also, the Coast Guard published a 
notice of policy on October 4, 1996 (61 FR 51789), in the Federal 
Register. The Coast Guard received 30 letters commenting on the interim 
rule. No public meeting was requested, and none was held.

Drafting Information

    The principal persons involved in drafting this document are Mr. 
Gerald P. Miante, Office of Design and Engineering (G-MSE-3), and Mr. 
Stephen H. Barber, Project Counsel, Office of Chief Counsel.

Purpose

    Under the authorities cited in the ``Authority'' section for each 
part amended, the Coast Guard is amending its electrical engineering 
and equipment regulations for certain Coast Guard-inspected vessels in 
46 CFR chapter I, subchapters I-A, J, and Q to accomplish the 
following:
    (1) To reduce the regulatory burden on the marine industry by 
eliminating obsolete and unnecessary regulations and by clarifying the 
remaining ones. This objective is consistent with the President's 
Regulatory Reinvention Initiative and the Coast Guard's regulatory 
reform program.
    (2) To replace, where appropriate, requirements that are 
prescriptive in nature with performance-based requirements that 
incorporate national or international standards and allow increased 
flexibility for small businesses.
    (3) To eliminate requirements that create an unwarranted 
differential between domestic rules and international standards. This 
rulemaking harmonizes, where possible, the electrical engineering 
regulations with amendments to the International Convention for the 
Safety of Life at Sea, 1974, (SOLAS 74) since the electrical 
engineering regulations were last revised in 1982.
    (4) To address comments received from the marine industry and from 
Coast Guard field and inspection offices.
    This rulemaking is intended to serve the needs of industry while 
maintaining a comparable level of safety.

Discussion of Comments and Changes

    The following is a summary of the comments received and the changes 
made to the regulatory text since the interim rule was published. The 
items are grouped first by those that address a general issue, then by 
those that relate to a specific provision in the text.

I. General Comments.

    (1) Several comments congratulated the Coast Guard for its revision 
of subchapter J which offers the manufacturers more flexibility, 
increases clarity of the regulations and enhances safety of U.S. flag 
vessels. It was observed that the revision process reflects a lot of 
``hard work and good common sense.''
    (2) As in response to the NPRM, a number of comments recommended 
changes that may require further consideration by the Coast Guard. 
Several comments recommended that certain other standards be referenced 
in the regulations as replacements for, or options to, those cited in 
the interim rule. However, not all changes could be incorporated at 
this final rule stage, due to the complexity of the requests or the 
necessity to allow the public an opportunity to comment on new 
requirements. Several additional standards for incorporation by 
reference are included in this final rule.
    The Coast Guard has a long-range plan to broaden the use of 
acceptable standards. Until those standards are incorporated into the 
regulations, any vessel owner or operator who desires to employ a 
fitting, material, apparatus, equipment, or arrangement other than that 
required by this subchapter may submit a request using the equivalency 
provision in Sec. 110.20-1.

Items the Coast Guard may consider for a subsequent rulemaking 
include--

    (a) Incorporation of the new Institute of Electronic and Electrical 
Engineers (IEEE) Std 45, when approved by the IEEE standards board and 
published;
    (b) Addition of a requirement that all manufacturer's conducting 
self-certification should be International Organization for 
Standardization (ISO) 9001 registered;

[[Page 23895]]

    (c) Incorporation of performance-based inclination criteria into 
Sec. 111.01-19;
    (d) Consideration of requirements for high impedance grounding 
systems to be added to Sec. 111.05-19;
    (e) Establishing a new subpart that would address the necessary 
supply of clean, uninterrupted power for modern AC-powered, solid-state 
equipment, which would complement the requirements of Secs. 111.15-3 
and 111.20-1;
    (f) Addition of a ventilation alarm requirement to Sec. 
111.35-1.
    (g) Prohibition of screw-in, porcelain or glass-cap fuses in 
subpart 111.53;
    (h) Incorporation of new standards that provide guidance for high 
voltage cable in Sec. 111.60-1(e);
    (i) Incorporation of the Canadian Standards Association
    (CSA) flame test CSA FT-4 either as another option or in place of 
American National Standards Institute/Underwriters Laboratories (ANSI/
UL) 1581 test VW-1 in Secs. 111.60-2 and 111.30-19(b)(4);
    (j) Incorporation of Underwriters Laboratories (UL) 2225 into 
Sec. 111.60-23(h) to provide guidance on the use of metal-clad (Type 
MC) cable in hazardous (classified) locations;
    (k) Incorporation of Illuminating Engineers Society
    (IES) Recommended Practice (RP) 12 for marine lighting in Sec. 
111.75-15(c);
    (l) Permission of third-party testing for lighting, appliances, oil 
immersion heaters, and electric heaters in Secs. 111.75-20, 111.85-1, 
and 111.87-3;
    (m) Incorporation of International Electrotechnical
    Commission (IEC) 1892 in Sec. 111.105-5 for electrical 
installations aboard mobile offshore drilling units (MODU's) and 
floating platforms;
    (n) Incorporation of pump room ventilation and monitoring 
requirements of American Bureau of Shipping (ABS), Rules for Building 
and Classing Steel Vessels, section 4/5.151.6 into Sec. 111.105-31;
    (o) Replacing IEC 332-3, Category A flame test with IEC 332-3, 
Category A/F in Sec. 111.107-1;
    (p) Restricting the color red for general emergency or fire alarms 
only in Sec. 113.25-10;
    (q) Application of the cable routing and fire testing requirement 
of Sec. 113.30-25(i) to all safety related circuits in part 113;
    (r) Incorporation of additional requirements in Sec. 
113.50-20 to align the regulations with the International Maritime 
Organization (IMO) Code of Alarms and Indicators; nd
    (s) Establishing a new subpart 113.70 for gas detection systems.
    (3) A number of comments commended the Coast Guard's effort to 
streamline its electrical regulations and incorporate industry 
standards, both domestic and international.
    Consistent with the President's Regulatory Reinvention Initiative, 
the Coast Guard is taking this approach in all its rulemaking projects.
    (4) Two comments voiced several specific concerns and requested 
extending the effective date of the interim rule by six months to allow 
the U.S. shipbuilding community an opportunity to compile detailed 
comments and suggestions regarding the change. Additionally, the 
comment specified major concerns relating to degree of protection 
requirements for enclosures, ambient temperatures for equipment, ground 
detection regulation, and marine battery installations.
    In response, the Coast Guard, after a detailed analysis of these 
concerns, determined that the extension of the comment period was 
unnecessary. In response to the comment's specific concerns and until 
this final rule could be finalized, the Coast Guard published a notice 
of policy for interim rule (61 FR 51789; October 4, 1996). This policy 
notice pointed out that persons wishing to apply a provision from the 
1996 draft of IEEE Std 45 or the 1996 ABS Rules for Building and 
Classing Steel Vessels instead of a provision in the interim rule could 
submit, for approval on a case-by-case basis, a request under the 
equivalency provisions in the interim rule.
    (5) One comment requested clarification on what standards are 
approved for incorporation by reference and who determines if a 
standard is approved.
    The Coast Guard determines which standards are acceptable for 
incorporation by reference. In order to use a system arrangement or 
individual piece of equipment that does not meet the standards 
incorporated by reference or the specific requirements in this 
subchapter, a request may be submitted under the equivalency provision 
of Sec. 110.20-1. Requests under the equivalency provision will be 
considered at the time a specific system design is submitted to the 
Coast Guard for plan review and may be accepted as part of the system 
plan approval.
    (6) Several comments indicated that, contrary to the Coast Guard's 
intentions, the interim rule significantly increases the cost of doing 
business internationally for U.S. shipyards. They expressed concern 
that equipment protection, temperature, and operational characteristic 
requirements have been increased beyond conventional practice. Due to 
this perceived increase in requirements, the comments stated that 
electrical equipment might require extensive additional testing to 
demonstrate operability. These comments also noted that the 
requirements for alarm, indicating and internal communications systems 
have been greatly expanded. Finally, the comments pointed out that the 
interim rule invokes requirements that did not previously exist and are 
not found in trade literature. The comments' specific concerns are 
addressed in the discussion of comments for the relative section.
    Generally, however, the perceived increases and changes to the 
requirements in the final rule are actually a harmonization of the 
Coast Guard's electrical engineering requirements with classification 
society (ABS) and international (IEC) performance-based standards.
    (7) One comment expressed concern that the Coast Guard is heavily 
reliant on ABS Rules when the ABS Rules may not be aligned with the 
requirements of the International Association of Classification 
Societies (IACS) Member Societies. Also, the comment expressed concern 
that the regulations unfairly forced Member Societies to follow ABS 
requirements for vessels operating in U.S. waters.
    The Coast Guard has traditionally incorporated by reference various 
sections of ABS Rules into its electrical engineering regulations. This 
rule expands on the use of ABS Rules as an option or alternative to 
prescriptive requirements. However, the incorporation by reference of 
specific ABS rules does not preclude the use of other rules approved 
for specific applications under the equivalency provisions in 
Sec. 110.20-1.
    Additionally, port state control inspections are performed mainly 
to determine compliance with SOLAS 74 and some related Coast Guard 
regulations. The requirements of subchapter J and its referenced 
material apply to Coast Guard-certificated, U.S.-flag vessels only and 
are not generally applicable to foreign vessels, unless specified 
elsewhere in Coast Guard regulations.
    (8) One comment recommended incorporating more performance-based 
standards and more Coast Guard policies to reduce the number of 
requests seeking equivalency determinations under these regulations. 
The comment expressed belief that adherence to performance standards

[[Page 23896]]

will foster greater innovation and improved overall safety.
    Throughout the regulation, the Coast Guard has incorporated, 
wherever possible, a significant number of additional industry 
standards, both domestic and international. Time and resource 
limitations prevent the inclusion of every applicable standard. The 
allowance of equivalencies would permit the inclusion of appropriate 
standards that the Coast Guard has yet to review. This practice does 
foster innovation and is consistent with the Coast Guard's intention to 
serve the needs of industry while maintaining a comparable level of 
safety.
    (9) Several comments pointed out that, at the time of the 
publication of the interim rule, which incorporated the 1995 ABS Rules 
for Building and Classing Steel Vessels, ABS had already published the 
1996 edition of these rules.
    The text of this final rule incorporates the ABS Rules for Building 
and Classing Steel Vessels, 1996 edition. ABS updated section 4/5 of 
the ABS Rules for Building and Classing Steel Vessels by incorporating 
international requirements and, at the same time, reorganized the 
section into a more user-friendly format by dividing it into parts and 
renumbering the paragraphs.

II. Comments to Specific Sections

    Section 110.01-3. (1) Now that the rule is finalized, the option of 
complying with regulations in effect at the time the alterations or 
modifications are made has been removed from paragraph (b). Compliance 
with this regulation is now mandatory.
    (2) Paragraph (c) has been amended to better define the term 
``conversion.''
    Section 110.10-1. (1) One comment suggested incorporating by 
reference IEEE Recommended Practice on Surge Voltages in Low-Voltage AC 
Power Circuits (IEEE Std 62.41-1991); UL 1449, Standard for Transient 
Voltage Surge Suppressors; and UL 1778, Standard for Uninterruptable 
Power Supply Equipment.
    These standards apply to uninterruptable power supplies (UPS) which 
are not presently addressed in these regulations. While the value of 
these standards are realized and their use is not prohibited by these 
regulations, the Coast Guard will not include specific provisions or 
requirements on this subject in this rule without allowing an 
opportunity for public comment.
    (2) One comment suggested that American Petroleum Institute (API) 
Recommended Practices (RP) should not be incorporated into these 
regulations because they set forth domestic practices for fixed 
platform and shoreside facilities and do not reflect international 
consensus for vessels. It was suggested to consider incorporation of 
IEC 1892, which is presently under development at an international 
level.
    The Coast Guard agrees and is awaiting the publication of the IEC 
standard for review. The Coast Guard may consider IEC 1892 in a 
subsequent rulemaking where the public will have an opportunity to 
comment. Until its publication, subchapter I-A, subparts 111.105 and 
111.107, of this chapter and Coast Guard policy provide guidance for 
MODU's and other Outer Continental Shelf (OCS) vessels.
    Section 110.15-1. (1) One comment recommended that the definition 
of ``independent laboratory'' be changed to clarify that the 
certification may not be performed in the absence of listing.
    The intent of the definition is to ensure that testing must always 
be performed but also recognizes that laboratories vary in the 
terminology of promulgating successful results. Certain laboratories 
``list'' products; other laboratories ``certify'' that products meet 
certain standards.
    (2) One comment suggested that the requirement for watertight 
enclosures of National Electrical Manufacturers Association (NEMA) Type 
6 or 6P is excessive and suggested that NEMA Type 4 or 4X most closely 
matches the IEEE Std 45 definition of watertight and exceeds the 
definition of waterproof.
    The Coast Guard agrees and the definitions of ``watertight'' and 
``waterproof'' have been revised in accordance with IEEE 100. Examples 
of industry accepted minimum degrees of protection requirements are 
included.
    (3) One comment stated that the increase in the degree of 
protection requirements for ``dripproof'' to IEC ingress protection 
(IP) 32 will cause manufacturers to redesign electrical installations 
aboard vessels; and IEC IP 22 is acceptable as the current industry 
standard. Additionally, the comment recommended reinstating NEMA 250 
Type 12 in this category.
    The Coast Guard agrees with all the recommendations and the 
definition of ``dripproof'' has been revised accordingly.
    Section 110.25-1. (1) One comment recommended adding wording to 
paragraph (i)(6) to clarify that, when required by the standard, proof 
of listing and certification must also be submitted. This change would 
align the regulatory language with the note to the same section.
    Paragraph (i)(6) has been revised accordingly.
    (2) Several comments suggested that, in the note to paragraph (n), 
items required to meet an industry standard should only be certified by 
an independent laboratory approved by the Commandant, and not simply 
self-certified by the manufacturer. One comment pointed out that 
elimination of this requirement would result in inferior equipment 
severely jeopardizing shipboard safety. The comment suggests that at a 
bare minimum any manufacturer conducting self-certification should be 
ISO 9001 registered, which requires third-party evaluation of the 
manufacturer's quality program.
    Before the recent revisions of subchapter J, the regulation in this 
area required proof of listing only for equipment required to meet UL 
standards; manufacturer's self-certification was allowed for other 
standards such as IEEE, NEMA, and ANSI. The interim rule modified this 
requirement by consolidating UL into the latter group. The Coast Guard 
may consider requiring manufacturers, who wish to self-certify, to be 
ISO 9001-registered in a subsequent rulemaking where the public will 
have an opportunity to comment.
    (3) One comment recommended removing from paragraph (c) Marine 
Safety Center (MSC) review of components to expedite review and 
eliminate redundant review by the MSC and the Officer in Charge, Marine 
Inspection (OCMI). The comment states that the certificate of 
inspection is a better measure of safety.
    The inspection for certification of a vessel cannot be conducted at 
the component level for most systems. The Coast Guard has a long-
standing policy to allow plan review by third parties, such as 
professional engineers and ABS, with oversight functions distributed 
between the MSC and OCMI. The Coast Guard continues to find component 
verification by the MSC necessary for these essential systems.
    Section 111.01-1. One comment suggested adding wording to prohibit 
the use of combustible materials in the construction of electrical 
equipment, for example, enclosures and foundations.
    It is Coast Guard policy, which is congruent with SOLAS 74, 
Regulations II-2/34 and 49, to avoid the unnecessary use of combustible 
materials. Therefore, new paragraph (b) has been added to this section.
    Section 111.01-9. (1) Several comments noted that, in paragraphs 
(a) and (c), IEC IP 32 is an unduly severe degree of protection instead 
of a NEMA 250 Type 2 enclosure and that IEC IP 22

[[Page 23897]]

is acceptable as the current industry standard.
    The Coast Guard agrees and has revised paragraphs (a) and (c) 
accordingly.
    (2) Several comments suggested that the Coast Guard incorporate by 
reference table 4/5B.1 of the 1996 ABS Rules for Building and Classing 
Steel Vessels as acceptable minimum degrees of protection.
    This table has been added to paragraph (b) and to the note to this 
section.
    (3) Several comments pointed out that the degree of protection 
requirements NEMA 250 Type 6 or 6P and IEC IP 67 are too severe to be 
designated as ``watertight''.
    The Coast Guard agrees and has revised the requirement to be NEMA 
250 Type 4 or 4X and IEC IP 56 in paragraph (b) of this section and 
wherever the watertight requirement appears in part 113 of this 
chapter.
    (4) One comment suggested that an addition be made to these 
regulations to avoid the possibility that the National Electrical Code 
(NEC) requirements for land-based equipment near seashores might exceed 
requirements in this subchapter.
    This subchapter addresses Coast Guard certificated vessels. Land-
based electrical installations fall under different standards and are 
not subject to this subchapter. The Coast Guard is not responsible for 
the development of NEC requirements.
    Section 111.01-15. (1) Several comments pointed out that, in 
paragraph (c), circuit breakers be allowed to be rated at 40  deg.C 
instead of 45  deg.C because this is in accordance with marine circuit 
breakers covered in UL 489, supplement SA incorporated into 
Sec. 111.54-1(b) of this chapter. This would not preclude the option of 
using 50  deg.C Navy type circuit breakers.
    Paragraph (c) has been revised accordingly.
    (2) One comment suggested that requiring a 55  deg.C rating for all 
control and instrumentation equipment will cause manufacturers to 
recertify and redesign equipment.
    The increase to 55  deg.C rating for these critical circuit 
elements is in harmony with ABS Rules for Building and Classing Steel 
Vessels, table 4/11.1, IEC 68, and IEC 92-101, table 4. Therefore, the 
requirement is retained.
    (3) One comment noted that an ambient temperature of 40  deg.C 
differs with the generally accepted IACS and IEC temperature of 45 
deg.C.
    The Coast Guard has accepted 40  deg.C electrical equipment with 
specific exceptions in areas of special concern as noted in this 
section.
    Section 111.01-17. One comment noted that the regulations establish 
new requirements and vendor testing to demonstrate operability.
    These requirements conform to the international standard IEC 92-101 
and 1996 ABS Rules for Building and Classing Steel Vessels, table 4/
5.1.
    Section 111.01-19. (1) One comment suggested that if the Coast 
Guard were to provide a performance-based inclination criteria, the 
result would be the elimination of equivalency determinations 
applicable to any single class of vessel.
    No performance criteria were submitted in response to the interim 
rule; however, the Coast Guard may consider any performance criteria 
submitted for incorporation into a subsequent rulemaking.
    (2) One comment recommended changing the wording to exclude certain 
items, such as dishwashers, toasters, and coffee makers, that are not 
necessary to the maneuvering and safety of the vessel.
    This section has been revised to apply these requirements to 
critical equipment and systems.
    (3) One comment stated that the new requirements, which ensure that 
all electrical equipment is operable under certain extreme conditions 
of list, roll, and trim, will result in greater expense due to the 
installation of new equipment requiring additional tests.
    Although this section has been revised to apply to critical 
systems, the inclination requirements are consistent with IEC 92-101, 
table 3.
    Section 111.05-7. (1) One comment noted that this section is 
redundant to Sec. 111.60-5.
    This section is retained because of its specific reference to 
armored cable and grounding.
    (2) One comment recommended removing the reference to IEC 92-3 
because this standard does not address installation guidance for armor 
and sheathing.
    The reference to IEC 92-3 is retained because several sections of 
Part 3 of the IEC publication, such as clauses 10.18 and 11.14, provide 
guidance for metallic armor and sheathing.
    Section 111.05-9. One comment recommended incorporating the 
American Boat and Yacht Council (ABYC) Standard E4 on lightning 
protection.
    The Coast Guard agrees that guidance is appropriate for lightning 
protection. The Coast Guard is incorporating the international standard 
IEC 92-401, Electrical Installations in Ships; Part 401: Installation 
and test of completed installation, section 10, Lightning Conductors.
    Section 111.05-19. One comment recommended additions to the 
regulation for permitting high-impedance grounding schemes on all 
vessels with a distribution voltage greater than 1,000 volts a.c. as 
this method becomes an important tool for circuit protection, fault 
coordination, and the limitation of equipment damage.
    While the value of this practice is realized and its use is not 
prohibited by these regulations, the Coast Guard will not include 
specific provisions or requirements on this subject in a final rule 
without allowing an opportunity for public comment. However, this final 
rule references this grounding method in Secs. 111.05-19 and 111.05-27.
    Section 111.05-23. (1) One comment suggested allowing either the 
ground detecting equipment or an alarm signal from the detecting 
equipment to be installed at the distribution switchboard via a control 
cable instead of bringing back a phase conductor to the main 
distribution switchboard. Also, the comment points out that allowing 
the detection equipment to remain near the transformer would also make 
it available for local troubleshooting.
    While this is the intent of paragraph (d), a note has been added to 
the paragraph for clarification.
    (2) One comment recommended that paragraph (d) should be revised to 
include only isolation devices greater than 10 kVA.
    Paragraph (d) has been revised to specify ``feeder'' circuits, 
regardless of the load.
    (3) One comment suggested that the increase in the required number 
of ground detector lights will have a great impact on the cost and 
space.
    The revisions to paragraph (d) discussed previously should address 
the concern of this comment by reducing the number of circuits 
monitored and method of monitoring.
    Section 111.05-27. One comment stated that the requirement to 
momentarily remove the indicating device is overly prescriptive and 
recommended a more performance-based requirement to permit new 
technology.
    The section has been revised to clarify intent.
    Section 111.05-33. (1) Several comments suggested revising this 
section to clarify safety grounds (bonding) versus system grounds so 
the language is technically accurate.
    This section has been revised accordingly.

[[Page 23898]]

    (2) Several comments noted that clarification is necessary in 
paragraph (b) to exclude ``system'' ground conductors which are 
required by Coast Guard policy to be equal in size to the current 
carrying conductors.
    Paragraph (b) has been revised accordingly.
    (3) One comment recommended revising the requirement to allow cable 
armor and Type MC cable sheath as a grounding conductor as long as the 
cable is third-party tested and listed (with its terminators) as 
approved for this application.
    Coast Guard historically has prohibited the use of marine shipboard 
cable braided armor or metallic sheath as the grounding conductor. Type 
MC cable installation is required to be in accordance with the NEC as 
stated in Sec. 111.60-23 of this chapter.
    Section 111.10-1. One comment requested a definition for the term 
``auxiliary propulsion'' since certain types of thrusters are designed 
for use as ``take-home'' propulsive devices and thrusters are 
specifically excluded from paragraph (a).
    The term ``auxiliary propulsion'' is revised to read ``propulsion 
auxiliary'' to clarify that the intended machinery includes items such 
as fuel oil service pumps, lube oil service pumps, purifiers, engine 
sea water and fresh water cooling pumps, and air ejection equipment. 
Non-conventional systems must be reviewed on a case-by-case basis to 
consider such a thruster or ``take-home'' motor in a systems 
relationship with the power generating equipment capacity.
    Section 111.10-9. One comment stated that propulsion and vessel 
control are the critical components of the specified loads. The comment 
noted that absent these systems, and given the ability of many safety 
systems to operate in the absence of distributed electric power, the 
additional redundancy and expense of two independent transformers is 
not justified.
    Most vessels rely on distributed electric power for system 
operation. Plans for any non-conventional system which does not rely on 
power from the transformers may be submitted for review in accordance 
with Sec. 110.20-1.
    Section 111.12-1. (1) One comment suggested that the Coast Guard 
accept other major classification societies besides ABS to eliminate 
differential between domestic rules and international standards. 
According to the comment, ABS Rules create a burden on equipment 
manufacturers with additional ``type-testing.''
    The Coast Guard has traditionally incorporated by reference various 
sections of ABS Rules into its electrical engineering regulations. This 
rule expands on the use of ABS Rules as an option or alternative to 
Coast Guard prescriptive requirements. However, the incorporation by 
reference of specific ABS rules does not preclude the use of other 
rules approved for specific applications under the equivalency 
provisions in Sec. 110.20-1, whereby the Coast Guard can consider 
alternative ``type-testing.''
    Since ABS is a member of IACS and has recently revised its 
electrical section 4/5 (section 4/3 of the ABS Rules for Building and 
Classing Mobile Offshore Drilling Units) to incorporate many IEC 
practices, the Coast Guard considers prime movers meeting these 
sections to be aligned with international standards.
    (2) One comment noted that neither Coast Guard regulations nor ABS 
Rules provide for automatic shutdown of a diesel generator's prime 
mover upon failure of that engine's pressure lubrication system.
    The requirement in paragraph (c) of this section is retained 
because, in addition to being sound engineering practice, table 4/11.10 
of the 1996 ABS Rules for Building and Classing Steel Vessels provides 
for automatic shutdown of diesel, steam, and gas turbine prime movers 
upon low lube oil inlet pressure to that engine as well as to the 
bearings of the electrical generator.
    Section 111.12-11. One comment recommended adding a new item to 
paragraph (c) which would require the circuit breaker for a generator 
to open upon the shutting down of the prime mover. This is a safety 
feature required by ABS Rules for Building and Classing Steel Vessels, 
1996, section 4/5A5.3.1.
    The inclusion of a low-voltage trip element, activated upon the 
shutting down of the prime mover, has always been a feature on 
generator circuit breakers and in the provisions of ABS Rules; however, 
this requirement has been absent from Coast Guard regulations.
    It is now added in new paragraph (c)(1).
    Section 111.15-2. (1) One comment noted that the requirements of 
this section will cause the U.S. marine industry to use specialized, 
more expensive batteries. Also, the addition of a special nameplate 
will increase costs.
    The Coast Guard utilizes regulations, incorporating Classification 
Society Rules and standards, to ensure that equipment aboard 
certificated vessels is suitable for the environment and the purpose 
for which it is installed. This is particularly applicable to equipment 
used in cases of emergency. Labeling of the product by the manufacturer 
to attest to certain conditions is a cost effective method of 
presenting this information to shipowners, operators, crew, and 
inspectors.
    (2) One comment recommended the use of a more performance-based 
standard instead of the specific requirements in paragraph (a). 
Performance standards would preclude the necessity for equivalency 
determinations for column stabilized units, surface effects vessels, 
etc.
    The requirement of 40 degrees of inclination is consistent with IEC 
92-101 and 92-305. Although a parameter for use of accumulator 
batteries in ships, a unit designed for the environmental conditions of 
marine installation should include this feature. The use of an 
accumulator battery that does not meet this parameter may be requested 
under the equivalency provision of Sec. 110.20-1. Submissions under the 
equivalency provision will be considered at the time a specific system 
design is submitted to the Coast Guard for plan review and may be 
accepted as part of the system plan approval.
    Section 111.15-3. One comment suggested the addition of a three 
pole disconnect switch located in the battery compartment of large 
battery installation with a nominal voltage of higher than 120 volts 
for use during servicing.
    This comment applies mainly to a large amount of cells for use with 
uninterruptable power supply units and may be considered for inclusion 
into a subsequent rulemaking where the public will have an opportunity 
to comment.
    Section 111.15-5. (1) One comment noted that, in paragraph (c), 
batteries are allowed in confined spaces if the batteries are sealed. 
The comment recommended that no batteries, sealed or otherwise, should 
be situated in confined areas because these units are only ``sealed'' 
if everything is normal and may vent as much as standard cells under 
abnormal conditions.
    Paragraph (c) has been revised accordingly.
    (2) One comment suggested that, in paragraph (e), it is sufficient 
for a battery to have indication of manufacturer and type number on the 
battery with documentation available to support the ampacity, 
construction, and specific gravity requirements.
    Battery documentation is usually obscure and unavailable for 
service personnel and inspectors and labeling is considered necessary 
for maintenance and inspection.

[[Page 23899]]

    Section 111.15-20. One comment recommended that, if the Coast Guard 
is going to specify ampacity considerations, then it should also 
specify a voltage drop in the criteria for cable sizing.
    Paragraph (c) has been revised to include the words ``while 
maintaining the proper voltage at the load end.''
    Section 111.15-30. One comment indicated that the purpose of this 
section is unclear and appears to be directed at a unique situation.
    The purpose of this section is to ensure that, from a systems 
engineering perspective, battery installations and their chargers are 
compatible. It also cautions against the use of some portable battery 
chargers which may impose an unintentional ground of the vessel's power 
supply system. Section 111.15-30 is retained.
    Section 111.20-1. (1) One comment suggested revising the 
requirement to allow only transformers rated at less than 500 VA to be 
installed in an enclosure as an alternative to the winding being 
inherently resistant to moisture, sea atmosphere, and oil vapor. It 
reasons that the long term integrity of enclosures for larger, 
permanently fixed transformers may not survive the life cycle of the 
vessel.
    This section is retained because it offers alternatives for this 
equipment. Should the enclosure choice be selected, design, plan 
review, installation, and inspection must all show suitability for 
environmental conditions and applicability to the system in which it is 
used.
    (2) One comment recommended revising the provision to allow an 
exception for inherently current limiting ferro-resonant transformers 
which are incorporated in a device meeting UL 1778.
    The Coast Guard determined that this equipment is for specific use 
and uninterruptable power supplies. As stated previously, 
uninterruptable power supplies will be addressed in the next revision 
of the electrical engineering regulations. Until that time, use of 
uninterruptable power supply systems are not specifically prohibited by 
these regulations, and their usage is subject to the normal plan review 
and inspection process.
    Section 111.30-5. (1) One comment noted that IEC 92-302 and 92-503 
do not define low and medium voltages but refer to voltage ranges. Only 
IEEE defines the terms.
    Paragraph (a) has been revised accordingly.
    (2) One comment suggested moving paragraph (b) to Sec. 111.01-9, 
Degrees of protection.
    Paragraph (b) specifically addresses dripping and falling 
substances, whereas, Sec. 111.01-9 addresses the universal enclosure 
requirements as outlined in the referenced standards.
    Sections 111.30-9, 111.30-11, and 111.30-13. One comment 
recommended that the provisions of these sections be reinstated. The 
comment suggests that these operational safety standards should be set 
as clear Coast Guard standards. The comment expressed a concern that if 
a crew member were to remove an insulated floor matting or grating for 
cosmetic reasons, the potential threat to safety would not be in 
violation to any clear cut Coast Guard requirement; only a violation to 
an obscure reference in a secondary document which might not be aboard 
the vessel.
    The features described in the previously removed Secs. 111.30-9 
(doors and non-conducting handrails) and 111.30-13 (grounding of 
switchboard instrumentation) are all construction features to be 
installed by the manufacturer in accordance with applicable standards. 
In reference to previously removed Sec. 111.30-11 (mats or gratings), 
the Coast Guard agrees that this is an important operational safety 
concern and that specific guidance is warranted. The reinstated 
performance-based requirement reflects international standards.
    Section 111.30-19. (1) One comment suggested adding punctuation to 
paragraph (b)(3) to clearly distinguish between switchboard wire and 
instrumentation wire.
    Paragraph (b)(3) has been revised accordingly.
    (2) Several comments indicated that paragraph (b)(6) and 
Sec. 111.60-11, paragraph (d) cross-reference each other for 
switchboard wiring and leave the requirements for switchboard wiring 
undefined.
    The requirements for switchboard wiring are found in paragraph (b) 
and its referenced standard. The cross-reference to Sec. 111.60-11 was 
unnecessary and has been removed.
    (3) One comment recommended changing the wire size in paragraph 
(b)(3) to #18 AWG to align with Sec. 111.60-4.
    The #14 AWG wire size requirement in this section is specific to 
switchboard wiring, whereas the #18 AWG allowance in Sec. 111.60-4 is 
for general wiring such as lighting fixtures or other uses where 
appropriate.
    Section 111.30-21. One comment recommended retaining this section 
with modifications to allow devices which operate at elevated 
temperatures, but are self-cooling and do not adversely affect 
surrounding components.
    The Coast Guard determined that the requirements removed from the 
regulations are sufficiently addressed in the relevant construction 
standards.
    Section 111.30-24. One comment requested clarification on the word 
``floating.''
    As discussed in the preamble to the interim rule, on page 28264, a 
comment to the NPRM requested that exclusion for a non-self propelled 
MODU be expanded to include other OCS facilities. Since subchapter J is 
not universally applicable to fixed platforms, the Coast Guard accepted 
the comment's suggestion to specify ``floating'' units which are 
subject to the provisions of this subchapter such as tension leg 
platforms (TLP) and semi-submersible production platforms.
    Section 111.30-25. Two comments noted that this section, which was 
not addressed in the NPRM or the interim rule, is highly prescriptive 
and limits the use of newer technologies.
    The Coast Guard has determined that any new equipment resulting 
from advances in technology that performs the same function as those 
devices listed in Sec. 111.30-25 can be considered for approval under 
Sec. 110.20-1. The list in Sec. 111.30-25 is retained because the Coast 
Guard determined it to be representative of those functions necessary 
for the safe operation of a vessel.
    Section 111.33-11. One comment recommended specifying that ``ABS 
Rules'' refers to the ABS Rules for Building and Classing Steel 
Vessels.
    The Coast Guard agrees and has changed the reference from ``ABS 
Rules'' to ``ABS Rules for Building and Classing Steel Vessels.'' 
Additionally, the reference to ``ABS MODU Rules'' has been changed to 
``ABS Rules for Building and Classing Mobile Offshore Drilling Units.''
    Section 111.35-1. One comment requested a revision to this section 
that requires an alarm indicating the failure of system ventilation.
    The Coast Guard may consider adding a requirement for an alarm 
indicating the failure of a ventilation system in a subsequent 
rulemaking where the public will have an opportunity to comment.
    Section 111.40-1. One comment noted that the deletion of this 
section would result in the installation of panelboards never intended 
for the marine environment. The comment suggests incorporating IEEE Std 
45 to provide guidance for the construction of panelboards.

[[Page 23900]]

    The Coast Guard agrees and is adding the suggested reference 
because of its wide acceptance in the marine field.
    Section 111.51-3. One comment pointed out that wording is missing 
from this section which would ensure proper protective device 
coordination in all cases and round out the coordination declaration 
made in Sec. 111.51-1.
    The Coast Guard agrees and the section is revised accordingly by 
the addition of new paragraph (a).
    Section 111.53. One comment suggested adding specific wording that 
prohibits the use of any fuse holder constructed of porcelain or 
ceramic materials or any fuse that is of the screw-in type.
    The Coast Guard is reviewing the safety implications of screw-in 
type fuses and may consider prohibiting those fuses in a subsequent 
rulemaking where the public will have an opportunity to comment.
    Section 111.54-1. One comment suggested referencing IEC 56 for 
circuit breakers above 1000 volts in place of the reference in 
paragraph (c)(3)(ii) to IEC 947-2 for medium voltage circuit breakers.
    The Coast Guard agrees that the appropriate standard for circuit 
breakers above 1000 volts is IEC 56. Paragraph (c)(3)(ii) is revised 
accordingly.
    Section111.60-1. (1) One comment noted that in paragraph (a) the 
word ``cooper'' should be changed to the word ``copper.''
    Paragraph (a) has been revised accordingly.
    (2) Several comments requested reinstatement of MIL-C-915F cable 
pointing out that this is a current Navy standard and another comment 
suggested further the addition of ``amendment 2'' to the MIL 
specification.
    The Naval Sea Systems Command (NAVSEA) electrical office has 
informed the Coast Guard that MIL-C-915 cable is not being installed in 
new construction or major modifications. Additionally, its supply of 
MIL-C-915 cable has been cut-up and sold for scrap.
    (3) One comment suggested that marine shipboard cable listed by a 
Nationally Recognized Testing Laboratory (NRTL) accepted by the 
Commandant is acceptable for use.
    The term ``NRTL'' is most commonly used by Occupational Safety and 
Health Administration (OSHA) for safety-type testing, whereas cable 
testing includes physical testing as well as fire testing. The Coast 
Guard maintains a list of independent testing laboratories accepted by 
the Commandant for this purpose. Present Coast Guard policy is 
consistent with the suggestion.
    (4) One comment suggested deleting the terms ``construction'' and 
``identification'' from paragraph (a) and recommended that all cable 
must meet the performance requirements in IEEE Std 45.
    As stated in paragraph (d), all electrical cable must now meet the 
performance requirements of section 18 of IEEE Std 45.
    (5) One comment recommended for inclusion in paragraph
    (f) Type TC and Type ITC cables for industrial applications.
    Section 111.107-1 contains the regulations for industrial systems 
and cables. Special purpose or ship-specific equipment can be accepted 
as equivalent under Sec. 110.20-1 during plan review.
    (6) One comment recommended that incorporating IEC 92-3, removing 
the words ``and identification'' from paragraph (a), and removing the 
words ``and marking'' from paragraph (d) would result in economical 
cables for shipbuilders. If this is not an option, the comment suggests 
that the Coast Guard accept the minimum markings instead of requiring 
the more extensive markings of IEEE Std 45.
    The Coast Guard has determined that the minimum marking 
requirements are those in IEEE Std 45. The IEEE Std 45 markings 
constitute the five basic pieces of information necessary for minimum 
identification.
    (7) One comment suggested deleting paragraph (d) because it 
unnecessarily adds additional performance requirements to material and 
finished products which have met its particular standard.
    Paragraph (d) is retained because it ensures IEEE Std 45 
performance standards are met and guarantees that minimum safety 
criteria are upheld.
    (8) One comment suggested an editorial change in paragraph (f) to 
correctly reference the IADC standard as an application standard.
    Paragraph (f) has been revised accordingly.
    (9) One comment recommended that in paragraph (e) the regulation 
should specify a standard for high-voltage cable that is acceptable to 
the Coast Guard.
    Presently, IEEE Std 45 and IEC 92-3 as well as several MIL 
specifications and UL 1072 form the acceptable standards. The Coast 
Guard may consider IEC 92-354 and IEC 502 in a subsequent rulemaking 
where the public will have an opportunity to comment.
    Section 111.60-2. (1) One comment suggested deleting the reference 
to ANSI/UL 1581 test VW-1 because it does not guarantee a degree of 
flame propagation resistance such as the other specifications mentioned 
in this section. It recommended replacing it with an alternate test CSA 
FT-4.
    The flammability tests in this section are retained. The Coast 
Guard may consider test CSA FT-4 in a subsequent rulemaking where the 
public will have an opportunity to comment.
    (2) One comment suggested that it is not necessary to physically 
separate specialty cable from other cable in all installations.
    Paragraph (a) requires physical separation only if the flammability 
tests in the introductory text of this section cannot be met.
    (3) One comment recommended paragraph (b) be applied only to cable 
runs installed in enclosed locations.
    Cable that cannot meet minimum flammability requirements must 
comply with both paragraphs (a) and (b) to reduce the risk of flame 
spreading among cable runs and throughout the vessel.
    Section 111.60-3. Several comments suggested revising paragraph (d) 
to encompass special applications referred to throughout section 19 of 
IEEE Std 45 and not limiting the focus on the particular application in 
19.6.5 of the standard.
    Paragraph (d) has been revised accordingly.
    Section 111.60-4. One comment noted that the listed metric 
conversions of AWG sizes do not correspond to standard metric wire 
sizes. The comment suggests listing standard metric wire sizes that are 
acceptable in lieu of the AWG sizes.
    The metric sizes that accompany AWG numbers are provided as 
approximate metric dimensions and are ``soft'' conversions from the AWG 
circular mil equivalents. Actual metric nominal size is found to differ 
between such standards as JIS and European. Also, other wire gauge 
systems exist such as British Standard and Birmingham whose nominal 
sizes and actual dimensions differ from AWG and metrics. Electrical 
plans are reviewed and approved by the Coast Guard usually with an AWG 
size listed and annotated with ``or equivalent.'' It is up to the 
designer to choose a cable with conductors capable of equal or greater 
ampacity which will pass final inspection upon installation.
    Sec. 111.60-11. (1) One comment suggested modifying the section 
title to read ``Wire (other than ground conductors).''
    The Coast Guard determined that this change is unnecessary because 
this

[[Page 23901]]

section is self-explanatory and grounding conductors are covered 
elsewhere.
    (2) One comment recommended qualifying the word ``enclosure'' as 
``equipment enclosure.''
    The Coast Guard determined that the suggested clarification is 
unnecessary because wire is allowed in junction boxes, controllers, and 
switchboards as well as equipment enclosures, for example, lighting 
fixtures and motors.
    (3) One comment suggested revising paragraph (c) to reference the 
appropriate standards for wire relative to IEEE Std 45.
    Paragraph (c) has been revised accordingly.
    Sec. 111.60-17. (1) One comment suggested including specific 
requirements for crimped ferrules or pin terminals to prevent loose 
strands of wire causing shorts when used with compression type 
terminals.
    The Coast Guard determined that this is an installation quality 
control issue addressed under the general requirements in Sec. 111.10-1 
for electrical installations.
    (2) Several comments recommended prohibiting twist-on type 
connectors, recommended including a referenced standard or method of 
securing them to prevent loosening, or recommended eliminating 
paragraph (b).
    The Coast Guard determined that this, again, is an installation 
quality control issue addressed under the general requirements in 
Sec. 111.10-1 for electrical installations. Twist-on connectors must be 
installed in accordance with this entire section; safety is maintained 
with proper installation. Industry has requested, and Executive Order 
12866 demands, that government agencies include more performance-based 
requirements rather than prescriptive regulation. Section 111.60-17 is 
an example of the inclusion of a performance-based standard and 
presents an allowance for other methods or new technology which meet 
the same criteria.
    Sec. 111.60-19. One comment recommended revising paragraph (a) to 
allow temporary splices within an enclosure in hazardous locations for 
repair operations necessitated by damaged cable, where replacement of 
such damaged cable would shut down vessel operations. The spliced cable 
run could then be replaced at a later date while the vessel is in a 
shipyard.
    The Coast Guard takes into consideration the economic conditions 
and mission of the vessels it regulates, but its primary concern is the 
safety of these vessels and their crews.
    It is the responsibility of certain persons in charge of a vessel 
to notify the Coast Guard in the event of a marine casualty, accident, 
or serious marine incident. The cognizant OCMI will determine the 
course of action to be taken, notwithstanding temporary repairs of an 
emergency nature which might be deemed necessary by the master.
    Sec. 111.60-23. (1) Several comments applauded the proposal to 
allow limited use of Type MC cable. One comment noted that Type MC 
cable had been used in the marine environment for more than 20 years. 
It states that Type MC cable meeting the standards as proposed provides 
an acceptable alternative while maintaining safety.
    (2) One comment expressed concern that a disproportionate number of 
comments support the prohibition or restriction of Type MC cable in 
marine locations.
    The Coast Guard determines regulatory policy based on the substance 
of comments, rather than the number of comments, on a subject.
    (3) Several comments recommended that instrument tray cable (ITC) 
(300 volt insulation) with similar Type MC cable construction be 
allowed where allowed by NEC standards.
    Article 90-2(b) of the NEC states that the code does not generally 
cover installations on vessels. NEC standards do not apply to Coast 
Guard certificated vessels, unless specifically incorporated by 
reference in this subchapter.
    Alignment with NEC standards is not necessarily an objective of 
this rulemaking. ITC cable has not been evaluated for use aboard 
vessels.
    (4) One comment noted that Sec. 111.60-23(a) refers to ``vessels'' 
whereas paragraphs (c)(2) and (g) refer to ``offshore floating drilling 
and production facilities.''
    The term ``vessel'' is broadly defined in section 3 of title 1 of 
the U.S. Code to include floating production units, mobile offshore 
drilling units, and ships. Paragraphs (c)(2) and (g) apply only to 
offshore floating, drilling and production facilities.
    (5) Several comments suggested that the word ``welded'' as used in 
the term ``continuously welded corrugated metal-clad (CWCMC) cable'' be 
removed throughout Sec. 111.60-23 to conform with commercial 
terminology. This will provide a continuous impervious corrugated metal 
sheath manufactured by either the extrusion or welded process.
    The term ``continuously welded corrugated metal-clad (CWCMC) 
cable'' in paragraph (a) has been changed to ``continuous corrugated 
metal-clad cable'' and paragraph b(1) and paragraph (h) have been 
changed accordingly.
    (6) One comment questioned why only corrugated as opposed to non-
corrugated Type MC cable is allowed.
    Non-corrugated Type MC cable does not have the flexibility 
necessary for use on vessels or floating facilities. Corrugated cable 
would be less susceptible to cracking under these conditions.
    (7) Several comments recommended that the requirement for the UBVZ 
listing on Type MC cable be removed. One comment stated that the UBVZ 
listing does not affect construction of the cable or its suitability 
for use on vessels, but does affect cable pricing and availability.
    The Coast Guard agrees. The UBVZ listing has been removed from 
paragraph (b). This removal is also consistent with the Coast Guard's 
position that metal-clad cable is a code product and not a marine 
shipboard cable.
    (8) One comment recommended that the term ``impervious'' in 
reference to the sheath of the cable be changed to ``gas/vaportight'' 
because ``gas/vaportight'' is an NEC term.
    The terms ``gas-tight'' and ``vapor-tight'' have been added for 
clarity.
    (9) One comment suggested that the term ``close-fitting'' be 
removed as undefined.
    The words ``close-fitting around the conductors and fillers'' have 
been added for clarity.
    (10) One comment stated that paragraph (b) was unclear as to what 
an independent laboratory was to certify or list.
    Paragraphs (b)(2) and (b)(3) have been combined to correct this 
discrepancy.
    (11) Two comments recommended that the restrictions for
    Type MC cable in paragraph (c)(1) should be moved to Sec. 111.60-3 
because they are applicable to all cables.
    Type MC cable must be treated separately because it is not suitable 
for applications such as elevators. Marine shipboard cable, described 
in Sec. 111.60-1, must be used for all the services in paragraph (c).
    (12) Two comments suggested that Type MC cable should be allowed in 
drilling function areas as it is recognized by API RP 14F for use on 
fixed production facilities.
    API RP 14F applies only to fixed facilities. This subchapter does 
not apply to fixed facilities.
    (13) Several comments recommended removing paragraphs (c)(2) and 
(g). They contend that these paragraphs are prescriptive and are 
already covered

[[Page 23902]]

under the performance standard in paragraph (c)(1).
    Paragraphs (c)(1) and (c)(2) have been combined for clarity and 
paragraph (g) is retained. The Coast Guard does not allow the use of 
Type MC cable in areas that are inherently subject to high vibration or 
the other conditions specified in paragraph (c).
    (14) Several comments suggested that installation of Type MC cable 
not be limited to article 334 because other articles within the NEC are 
also applicable.
    The other applicable articles are already referenced in article 
334.
    (15) Two comments recommended the acceptance of table A6 of IEEE 
Std 45 as well as the ampacity tables given in the NEC since both are 
based on the same method of calculation.
    Type MC cable is a code product, to be installed in accordance with 
article 334 of the NEC and, therefore, the NEC's ampacity tables are to 
be used.
    (16) Several comments suggested that the metallic sheath of Type MC 
cable be allowed for use as a grounding conductor.
    The Coast Guard determined that there is insufficient historical 
data on the use of Type MC cable on vessels to allow the metallic 
sheath to be used as a grounding conductor. Even on shipboard cable, 
the Coast Guard has never allowed braided armor to be used as a 
grounding conductor. The Coast Guard maintains this policy with Type MC 
cable.
    (17) Many comments suggested removing the prohibition of the use of 
Type MC cable as interconnection between drilling and production 
modules.
    The Coast Guard has revised paragraph (g) to allow Type MC cable to 
be used as interconnection between drilling and production modules on 
the same platform. Type MC cable is still prohibited as interconnection 
between temporary drilling packages and platform production modules.
    (18) The Coast Guard is aware of the recently published UL 2225, 
Metal-Clad Cables and Cable-Sealing Fittings For Use in Hazardous 
(Classified) Locations, and may consider it as a reference in paragraph 
(h) in a subsequent rulemaking where the public will have an 
opportunity to comment.
    (19) One comment recommended that paragraph (h) be revised to avoid 
confusion between terminations and fittings for Type MC cable and those 
for similar cable, such as TECK.
    Paragraph (h) has been revised to assure that fittings and 
terminations used must be compatible with the particular Type MC cable 
used.
    Section 111.70-1. One comment stated that it is unsafe to allow one 
phase to remain connected in ungrounded three-phase alternating current 
systems.
    Paragraph (b) of this section refers to the controller/motor 
overload relay and not the main disconnect device to isolate the 
controller/motor from the power source. Paragraph (a) includes a 
reference to ABS Rules for Building and Classing Steel Vessels 
addressing the main disconnect and its relationship to the motor-
running protective devices. Additionally, language has been added to 
paragraph (b) to clarify that the opening of two phases refers to the 
controller/motor overload devices.
    Section 111.70-3. (1) One comment suggested a revision to paragraph 
(d)(1), by replacing ``and'' with ``or'' to clarify that when both a 
controller and motor control center exist the identification 
information should only be required at one of the two.
    Motor control centers group individual controllers into a central 
location instead of installing each controller locally near its motor. 
Normally, the use of one precludes the use of the other for a 
particular motor.
    (2) One comment suggested eliminating items (v) and (vii) in 
paragraph (d)(1) and listing information sufficient to identify the 
motor controlled, its load, voltage and phase.
    The requirements in paragraph (d)(1) are consistent with IEEE Std 
45 and in keeping with standard engineering practice to provide 
important information necessary for the safe operation of the 
electrical system.
    Section 111.70-7. One comment recommended an editorial change in 
paragraph (d)(2) concerning the requirements of the disconnect device.
    Paragraph (d)(2) has been revised accordingly.
    Section 111.75-5. One comment recommended that in paragraph (b) the 
term ``lamp sizes'' be changed to ``fixture ratings'', and retain the 
minimum 50 watt requirement for convenience receptacles or IEEE Std 45, 
paragraph 21.6 be referenced.
    Paragraph (b) has been revised accordingly.
    Section 111.75-15. One comment indicated that the text of paragraph 
(c) is vague, providing no firm guidance. The comment suggests 
incorporating IES RP 12, Recommended Practice for Marine Lighting.
    The Coast Guard may consider IES RP 12 in a subsequent rulemaking 
where the public will have an opportunity to comment.
    Section 111.75-17. (1) One comment suggested that the term ``range 
light'' in paragraphs (b) and (c) either needs to be defined or 
replaced with the term ``masthead light.''
    The Coast Guard agrees and is removing the term ``range light'' 
which is now referred to in the Convention on International Regulations 
for Preventing Collisions at Sea, 1972 (72 COLREGS) as ``a second 
masthead light.''
    (2) One comment recommended the inclusion of specific photometric 
requirements for battery powered navigation lights.
    The Navigation Safety Advisory Committee (NAVSAC) reviewed the 
adequacy of lighting on barges, which is generally powered by battery, 
and concluded that no lighting requirement changes were necessary.
    Section 111.75-20. (1) One comment recommended revising paragraph 
(a) so that it is clear that the paragraph does not apply to lighting 
fixtures in hazardous locations.
    The Coast Guard is revising paragraph (a) accordingly.
    (2) Two comments suggested replacing the term ``meet'' with the 
term(s) ``listed/certified'' to provide a means of verifying compliance 
with any industry standard and requiring lighting fixtures to be tested 
by an independent third party.
    It is Coast Guard policy that when a referenced standard requires 
testing then the procedure is part of the regulation. Since the Coast 
Guard maintains a process of independent laboratory acceptance by the 
Commandant for items such as fire detection systems, cable, and marine 
lighting fixtures, it is also part of our policy that such testing be 
certified at these laboratories. The Coast Guard may consider third 
party testing in a subsequent rulemaking where the public will have an 
opportunity to comment.
    Section 111.85-1. One comment recommended that each oil immersion 
heater be tested by an independent third party testing institution.
    An added requirement for compliance with a specific standard and 
subsequent testing by a third party cannot be placed in this final rule 
without opportunity for public comment. Recognizing the safety 
implications of the equipment, the Coast Guard may consider the 
inclusion of applicable safety standards and testing arrangements for a 
subsequent rulemaking where the public will have an opportunity to 
comment. Presently, guidance is afforded to both manufacturer and user 
in subpart 111.01 of this chapter which establishes general criteria 
for all electrical equipment so that it is appropriate for the

[[Page 23903]]

environment and purpose for which it is installed.
    Section 111.87-3. One comment suggested that in paragraph (a) 
deleting the word ``meet'' and substituting the words ``listed/
certified.''
    It is Coast Guard policy that when a referenced standard requires 
testing then the procedure is part of the regulation. Since the Coast 
Guard maintains a process of independent laboratory acceptance by the 
Commandant for items such as fire detection systems, cable, and marine 
lighting fixtures, it is also part of our policy that such testing be 
certified at these laboratories. The Coast Guard may consider third 
party testing in a subsequent rulemaking where the public will have an 
opportunity to comment.
    Section 111.105. Several comments indicated that the obsolete MI 
Type cable, referenced in Sec. 111.105-17, paragraph (a), has been 
eliminated by the proposed IEEE Std 45 and should also be removed from 
these regulations. Additionally, with new technologies in cable jacket 
chemistry, these comments suggested that the armor requirements for 
hazardous location cables also be removed, as they have been for non-
hazardous areas.
    The Coast Guard agrees and subpart 111.105 has been revised 
accordingly.
    Section 111.105-3. Several comments recommended revising this 
section as it allows unarmored cable in hazardous locations.
    As indicated above in the discussion of comments for subpart 
111.105, the general requirement for armored cable in all hazardous 
locations has been removed.
    Section 111.105-5. One comment supports the inclusion of API RP 505 
as a criteria for system integrity, while another comment stated that 
it would be imprudent to consider the adoption of any API RP's because 
they are superseded by IEC documents addressing both MODU's and fixed 
platforms in a single comprehensive document.
    The API RP 505 is in draft form and as such is unavailable to the 
Coast Guard for review or to the public for purchase. When the document 
is published, the Coast Guard may consider API RP 505 for a subsequent 
rulemaking where the public will have an opportunity to comment.
    The IEC, in which the U.S. participates, is in the final draft 
stages of IEC Publication 1892 (IEC 1892), ``Mobile and Fixed Offshore 
Units--Electrical Installations.'' IEC 1892, part 3 addresses hazardous 
locations. This document reflects international consensus and will be 
considered for inclusion in these regulations in a subsequent 
rulemaking.
    Section 111.105-11. (1) One comment pointed out that the two 
standards referenced in paragraph (a) are not compatible because IEC 
79-11 defines two types of IS systems (Ia and Ib), whereas UL 913 
defines only one.
    The Coast Guard accepts the UL 913 definition or IEC 79-11 (Ia) 
only. Paragraph (a) has been revised accordingly.
    (2) Several comments recommended removing the option for shielded 
cable in paragraph (b)(1) because most shielding may be very thin and 
not suitable for safely providing sufficient isolation from non-IS 
circuits. Another comment recommended in paragraph (b)(1) removing the 
option for metallic armored cable since armoring is for mechanical 
protection and not to be substituted for an electromagnetic 
interference (EMI) shield.
    The purpose of paragraph (b)(1) is to offer options to protect 
intrinsically safe circuit cables from induced voltages generated by 
magnetic fields of non-intrinsically safe circuit cables. The Coast 
Guard agrees that an armored covering is not meant to function as an 
EMI shield. However, properly installed and grounded braided armor does 
afford some degree of protection depending on intercircuit parameters. 
Additionally, if a shielded cable is installed for protection, it is 
assumed that its dimensions have passed plan review and that it is 
suitable for the service intended. Both options are retained.
    Section 111.105-17. (1) One comment suggested clarifying the first 
sentence in paragraph (a) so that not all hazardous locations are 
required to have through runs of cable.
    The intention of paragraph (a) is that all hazardous areas be 
fitted with through runs of cable, therefore the requirement remains.
    (2) Several comments suggested that paragraph (a) be revised to 
require that cable in all hazardous locations be armored.
    As indicated above in the discussion of comments for subpart 
111.105, the general requirement for armored cable in all hazardous 
locations has been removed but the installation of armored cable 
remains as an option.
    Section 111.105-31. One comment suggested adding a new paragraph 
(f)(5) harmonizing Coast Guard and ABS requirements for pump room 
ventilation and monitoring.
    The Coast Guard recognizes the need for direction on this subject. 
However, new material must be presented to the public for comment 
before a final rule. The Coast Guard may consider these provisions for 
a subsequent rulemaking where the public will have an opportunity to 
comment.
    Section 111.107-1. One comment recommended removing the word 
``and'' in paragraph (c)(1)(i) and adding the word ``or'' since either 
standard will provide a comparable level of safety.
    This section has been revised accordingly.
    Section 112.05-5. One comment recommended modifying paragraph (d) 
to allow equipment that supports the emergency power source (e.g., fans 
and CO2 bottles).
    Paragraph (d) has been revised accordingly.
    Section 112.50-1. (1) One comment suggested adding a new paragraph 
(l) that requires the generator circuit breaker open upon the shutting 
down of the prime mover as required in ABS Rules for Building and 
Classing Steel Vessels section 4/5.119.1.
    A similar comment was directed towards Sec. 111.12-11, Generator 
protection, of this chapter. The requirement established in 
Sec. 111.12-11 is applicable to all generators. The equipment described 
in Sec. 112.50-1 are special features for emergency generators only. 
Therefore the restating of this requirement is unnecessary.
    (2) One comment indicated that in paragraph (d) the 45 second 
response time is longer than the 30 second response of the standby ship 
service generator required for unattended machinery plants in 46 CFR 
62.50-30(k)(2).
    The 45 second requirement in this section is for emergency 
generator sets and is aligned with SOLAS 74, Regulation II-1/42.3.1.2 
requirements. The 30 second requirement in 46 CFR part 62 is for a 
standby ship service generator in an unattended machinery space. If the 
standby ship service generator does not come on line within its 
allotted time, the emergency source would power its circuits shortly 
thereafter.
    Section 112.50-7. One comment indicated that paragraph (c)(3) 
appears to have been deleted.
    The five asterisks after paragraph (c)(2) indicates that the 
remainder of this section is retained. However, paragraph (d) is 
removed by the amendatory language of item 169 in the interim rule.
    Part 113. One comment pointed out that the title of several 
sections of this part use the words ``alarm system'' as a general term 
for the ``general emergency alarms and fire alarms.'' It suggested not 
using this terminology because it

[[Page 23904]]

typically describes ``machinery alarm systems.''
    In this part, the terminology is used with consideration of the 
context of each subpart. Wherever in this part the regulations 
reference the general emergency alarm system, the words ``general 
emergency alarm system'' are used. The more generic term of ``alarm 
system'' is used in reference to machinery alarm systems and other 
specialized alarms such as engineers' assistance needed, steering 
failure, and refrigerated spaces where appropriate.
    Section 113.05-7. (1) One comment noted that in paragraph (b) the 
reference to IEC 553 is a misprint and should read IEC 533 (entitled 
Electromagnetic Compatibility of Electrical and Electronic 
Installations in Ships) as stated in Sec. 110.10-1, Incorporation by 
reference.
    Paragraph (b) has been revised accordingly.
    (2) One comment stated that the environmental test requirements of 
this section are burdensome if applied to each new piece of equipment 
due to advances in technology and the continual development of new 
components. The comment suggested creating a self-certification 
requirement similar to 46 CFR 62.20-5, Self-certification.
    The Coast Guard does not deem self-certification as sufficient for 
this equipment. Testing of original and redesigned equipment required 
by subchapter Q to be Coast Guard ``approved'' is performed by 
independent laboratories accepted by the Commandant. The testing 
protocols and their results are strictly reviewed by the Coast Guard or 
designated third parties before an approval certificate is issued. 
Alarms that are allowed in 46 CFR part 62 to be self-certified must be 
designed to meet the environmental standards of 46 CFR 62.25-30, 
Environmental design standards, which reference ABS Rules for Building 
and Classing Steel Vessels. Subchapter J also references ABS (ABS Rules 
for Building and Classing Steel Vessels, table 4/11.1) for 
environmental testing requirements.
    Section 113.10-7. One comment suggested that the requirement for 
connection boxes to meet IEC IP 67 is unnecessarily severe.
    In all subparts where the interim rule required connection boxes to 
be NEMA 250 Type 6 or 6P or IEC IP 67, the requirement has changed to 
NEMA 250 Type 4 or 4X or IEC IP 56 to align the requirement with the 
definition of ``watertight.''
    Section 113.25-10. One comment suggested that red flashing lights 
be used only in conjunction with the general emergency alarm signal and 
for no other purpose. This is preferable to the IMO Code on Alarms and 
Indicators, which allows the color red to also be used when indicating 
the release of fire-extinguishing medium. A standardized color would 
allow quick identification and response by personnel.
    While the value of this practice is realized, the Coast Guard will 
not include specific provisions or requirements on this subject in this 
rule without allowing an opportunity for public comment. The term 
``flashing red lights'' has been changed to include rotating beacons as 
well.
    Section 113.25-11. One comment suggested revising the introductory 
sentence in Sec. 113.25-11 to read as follows, ``Each contact maker, 
where installed, must--''
    The Coast Guard determined that the requirements listed in this 
section apply to all contact makers, conventional or electronic type 
integrated in the public address system, and the addition of the words 
``where installed'' does not add to the clarity of the sentence.
    Section 113.25-12. One comment recommended in paragraph (a) the use 
of air operated alarm signals which may be actuated by a solenoid valve 
located outside the hazardous area.
    This section does not preclude air operated alarm signals or other 
types compatible with the environment in which they are used. Any new 
or non-conventional alarm signal will be considered in the plan review 
process.
    Section 113.30-3. One comment requested clarification of the phrase 
``must be independent of the ship's electrical system.'' The ship's 
electrical system may be interpreted to mean the ship's AC electrical 
system or the ship's DC system with a battery power source.
    The power for the emergency means of communication required by this 
subpart must not be reliant upon the vessel's normal source or 
emergency source of AC or DC power. Acceptable methods of power include 
sound-powered phone, telephone systems which are powered by hand 
cranked generators which charge capacitor circuits, and individually 
battery powered devices.
    Section 113.30-5. (1) One comment suggested that in paragraph (a) a 
cross-reference to 46 CFR 62.50-20(f)(2) be added.
    The cross-reference to 46 CFR 62.50-20 has been added.
    (2) One comment recommended editorial revision to paragraph (h)(1) 
for clarity.
    Paragraph (h)(1) has been revised accordingly.
    Section 113.30-25. (1) One comment indicated in paragraph (i) that 
cables for safety related circuits should only be permitted to be 
routed through high fire risk areas if it is technically impractical to 
route them otherwise or if they serve circuits within the high risk 
area. In either case, cables should be of the fire resistant type. The 
comment stated that decisions in these areas should not be affected by 
commercial considerations.
    The Coast Guard develops its regulations with the primary 
consideration being safety. Any commercial consideration would be 
secondary and related to cost savings to the industry through 
harmonizing with domestic and international industry standards 
resulting in additional options.
    Section 111.60-1 requires that accepted marine shipboard cable must 
meet the respective flammability tests contained in the referenced or 
companion standards. These tests are a validation that the cable is 
``flame retardant''; i.e., that the flame is not propagated. IEC 331, 
however, measures the ``fire-resisting'' characteristics as noted in 
the scope ``as one which will continue to function normally during and 
after a prolonged fire.''
    As published in the interim rule, paragraph (i) states that cable 
runs through high fire risk areas, which includes servicing equipment 
within these areas, must meet IEC 331. It is the intent that such 
cables not only prevent the proliferation of flame but also maintain 
service to the equipment as well.
    (2) One comment suggested modifying the last line of paragraph (e) 
to read ``an emergency power source'' instead of ``the vessel's 
electric system.''
    The paragraph has been revised to clarify which vessel's electric 
source is intended.
    Section 113.43-3. The reference to Secs. 58.25-45 and 111.93-9 is 
out-of-date and has been corrected.
    Section 113.50-15. One comment noted that, as written, this section 
appears to require explosionproof speakers in hazardous locations, for 
example, a cargo pump room on a tanker. The comment requests review of 
this requirement to determine whether it is excessive.
    All systems and enclosures for hazardous locations must be 
certified for the particular Class and Division (Zone) in which they 
are installed. In the example given, if the speaker system were to be 
found intrinsically safe during plan review, then explosionproof 
speakers would not be required. Alternatively, if a study did not prove 
that the speakers were necessary in that

[[Page 23905]]

location, they would be disallowed under Sec. 111.105-31(f) or, if 
proven necessary, they must be explosionproof.
    Section 113.50-20. One comment suggested adding additional 
requirements applicable to public rooms, alleyways, and stairways to 
align the regulations with the IMO Code of Alarms and Indicators.
    The Coast Guard may consider additional requirements to align 
Sec. 113.50-20 with the IMO Code on Alarms and Indicators in a 
subsequent rulemaking where the public will have an opportunity to 
comment.
    Section 113.70. One comment recommended adding a new subpart that 
addresses the installation and operation of gas detection systems. The 
comment suggests these systems meet the general requirements of the 
International Society for Measurement and Control (ISA) SP12.13 parts I 
and II.
    The Coast Guard may consider additional requirements for gas 
detection systems in a subsequent rulemaking where the public will have 
an opportunity to comment.
    Section 161.002-1. Components for automatic fire detection systems, 
EN54 parts 1 through 11, published by the European Committee for 
Standardization (CEN) remain absent from this section because several 
of the documents obtained by the Coast Guard were in draft form. The 
Coast Guard may consider the finalized documents for a subsequent 
rulemaking where the public will have an opportunity to comment.

Incorporation by Reference

    The Director of the Federal Register has approved the material in 
Secs. 110.10-1 and 161.002-1 for incorporation by reference under 5 
U.S.C. 552 and 1 CFR part 51. Copies of the material are available from 
the source listed in those sections.

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. It 
has not been reviewed by the Office of Management and Budget 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). A Regulatory Evaluation under paragraph 10e of the 
regulatory policies and procedures of DOT is available in the docket 
for inspection or copying where indicated under ADDRESSES. A summary of 
the Evaluation follows:
    Most of the changes to the regulations are either editorial or 
update technical specifications to reflect the latest practices. 
Although some of these changes will cause minor cost increases for 
shipbuilders, others will result in substantial savings. The cost 
increases resulting from these rules will be more than offset by the 
cost savings, due to relaxations in the rules. The Coast Guard 
estimates that the cost of complying with the rule over the next 10 
years will total $33,753,392 (in present value); but, this cost will be 
more than offset by the estimated net benefits of $73,538,213. This is 
a cost-benefit ratio of $1.00 of costs to $2.18 of benefits.
    Many of the changes causing cost increases are already current 
marine industry practices, such as an increase in the protection of 
cable from bilge water.
    There are several intangible benefits. Due to the increased use of 
national and international standards, certain items will now be more 
readily available ``off the shelf'' for marine use. A significant 
economic savings will result from the ability of equipment 
manufacturers, in many cases, to meet the new performance 
specifications instead of the old, prescriptive design standards. Also, 
the cost of submitting detailed plans and specifications to the Coast 
Guard for approval of certain equipment, such as sound powered 
telephones, emergency loudspeaker systems, and navigation lights, will 
be eliminated.
    No comments were received to the Regulatory Evaluation or its 
summary in the preamble to the interim rule.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the 
Coast Guard considered whether this final rule will have a significant 
economic impact on a substantial number of small entities. ``Small 
entities'' include small businesses, not-for-profit organizations that 
are independently owned and operated and are not dominant in their 
fields, and governmental jurisdictions with populations of less than 
50,000.
    This rule will affect entities that come under Standard Industrial 
Code (SIC) categories of 4412 through 4489 (Water Transportation) and 
1311 and 1381 (Oil and Gas Extraction), both groups of which are 
considered small entities if they have 500 or less employees, and under 
SIC category 3731 (Shipbuilding and Repair), which are considered small 
entities if they have 1,000 or less employees.
    The Coast Guard has taken measures to accommodate the interests of 
small entities during the development of this rule. The rule is limited 
to vessels that are constructed or undergo major modifications after 
September 30, 1996, thereby exempting the existing fleet from having to 
conform to these requirements. Furthermore, it is limited to Coast 
Guard-inspected commercial vessels, such as oil and chemical tankers, 
container ships, large passenger vessels, mobile offshore drilling 
units, research vessels, and school ships, which tend to be larger 
vessels. It does not apply to uninspected passenger vessels, commercial 
fishing vessels, or the overwhelming majority of inspected, small-
passenger vessels.
    To reduce the burden on small entities, this rule purges obsolete 
and out-of-date regulations and eliminates requirements that create an 
unwarranted differential between Coast Guard's regulations and industry 
standards. It enhances the flexibility of vessel owners, operators, 
manufacturers, and shipbuilders by incorporating, wherever possible, 
more options for compliance or by replacing prescriptive requirements 
with performance standards.
    This rule reduces costs by increasing choices available during the 
new construction or major modification of a vessel. As discussed under 
the Regulatory Evaluation section in this preamble, this rule will 
reduce costs of shipbuilding for all entities, whether large or small. 
The Coast Guard estimates that the cost of complying with the rule over 
the next 10 years will total $33,753,392 (in present value); but, this 
cost will be more than offset by the estimated net benefits of 
$73,538,213. This is a cost-benefit ratio of $1.00 of costs to $2.18 of 
benefits.
    Therefore, the Coast Guard certifies under section 605(b) of the 
Regulatory Flexibility Act (5 U.S.C. 601 et seq.) that this final rule 
will not have a significant economic impact on a substantial number of 
small entities.

Assistance for Small Entities

    In accordance with section 213(a) of the Small Business Regulatory 
Enforcement Fairness Act of 1996 (Pub. L. 104-121), the Coast Guard 
offers to assist small entities in understanding this rule so that they 
can better evaluate its effects on them. If your small business or 
organization is affected by this rule and you have questions concerning 
its provisions or options for compliance, please contact Ms. Laura 
Hamman, Office of Design and Engineering Standards, 202-267-2206.

[[Page 23906]]

Collection of Information

    This final rule provides for a collection of information under the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

    I. The following particulars apply to subpart 110.25:
    DOT No.: 2115.
    OMB Control No.: 2115-0115.
    Administration: U.S. Coast Guard.
    Title: Electrical Engineering Requirements for Merchant Vessels.
    Need for information: Subpart 110.25 requires industry to complete 
electrical engineering plans to meet performance requirements on newly 
built vessels and modifications of current vessels.

Proposed Use of Information

    This information is necessary to determine compliance with the 
electrical regulations before vessel construction or modification 
begins.
    Frequency of Response: The information must be submitted when a 
vessel is built or modified.
    Burden Estimate: 478 hours.
    Respondents: 175 owners or operators.
    Average Burden Hours per Respondent: 1 hour per submission.

    II. The following particulars apply to subpart 161.002:
    DOT No.: 2115.
    OMB Control No.: 2115-0121.
    Administration: U.S. Coast Guard.
    Title: Electrical Engineering Requirements for Merchant Vessels.
    Need for Information: Subpart 161.002 concerns application for type 
approval of fire protection systems.
    Proposed use of Information: This information is necessary to 
ensure compliance with the electrical regulations.
    Frequency of Response: A response is due each time initial approval 
is sought and each time a revision is requested.
    Burden Estimate: 60 hours.
    Respondents: 6 manufacturers.
    Average Burden Hours per Respondent: 10 hours per respondent.
    As required by 5 U.S.C. 3507(d), the Coast Guard submitted a copy 
of this rule to the Office of Management and Budget (OMB) for its 
review of the collection of information. OMB has approved the 
collection. The subpart numbers are 110.25 of subchapter J and 161.002 
of subchapter Q. The corresponding OMB approval numbers are OMB Control 
Number 2115-0115 for subpart 110.25, which expires on August 3, 1999, 
and OMB Control Number 2115-0121 for subpart 161.002, which expires 
September 30, 1999.
    Persons are not required to respond to a collection of information 
unless it displays a currently valid OMB control number.

Federalism

    The Coast Guard has analyzed this rule under the principles and 
criteria contained in Executive Order 12612 and has determined that 
this rule does not have sufficient federalism implications to warrant 
the preparation of a Federalism Assessment.

Environment

    The Coast Guard considered the environmental impact of this rule 
and concluded that, under paragraph 2.B.2.e(34)(d) and (e) of 
Commandant Instruction M16475.1B, this rule is categorically excluded 
from further environmental documentation. This rule concerns only 
system arrangement and equipment approval. The approved system 
arrangement and equipment required by this rule should contribute to 
the enhancement of vessel safety and, thereby, help to minimize impacts 
on the marine environment. A ``Categorical Exclusion Determination'' is 
available in the docket for inspection or copying where indicated under 
ADDRESSES.
