Electrical Engineering Requirements for Merchant Vessels

AGENCY: Coast Guard, DOT.

ACTION: Notice of proposed rulemaking.

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

SUMMARY: As part of the President's Regulatory Reinvention Initiative, 
the Coast Guard proposes to amend 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purge obsolete and out-of-date regulations, and eliminate requirements 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 proposed rulemaking would harmonize, 
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 proposed rulemaking would 
dramatically revise certain prescriptive electrical equipment design, 
specification, and approval requirements and replace them with 
performance-based requirements that incorporate international standrds.

DATES: Comments must be received on or before March 18, 1996.

ADDRESSES: Comments may be mailed to the Executive Secretary, Marine 
Safety Council (G-LRA/3406) (CGD 94-108), U.S. Coast Guard 
Headquarters, 2100 Second Street SW., Washington, DC 20593-0001, or may 
be delivered to room 3406 at the same address between 8 a.m. and 3 
p.m., Monday through Friday, except Federal holidays. The telephone 
number is (202) 267-1477. Comments on collection-of-information 
requirements must be mailed also to the Office of Information and 
Regulatory Affairs, Office of Management and Budget, 725 17th Street 
NW., Washington, DC 20503, ATTN: Desk Officer, U.S. Coast Guard.
    The Executive Secretary maintains the public docket for this 
rulemaking. Comments will become part of this docket and will be 
available for inspection or copying at room 3406, U.S. Coast Guard 
Headquarters, between 8 a.m. and 3 p.m., Monday through Friday, except 
Federal holidays.
    A copy of the material listed in ``Incorporation by Reference'' of 
this preamble is available for inspection at room 1300, U.S. Coast 
Guard Headquarters.

public hearing at a time and place announced by a later notice in the 
Federal Register.

Background and Purpose

    On March 30, 1995, the Coast Guard published a notice of a public 
meeting in the Federal Register (60 FR 16423) and solicited written 
comments on the President's recently announced Regulatory Reinvention 
Initiative as well as the Coast Guard's regulatory development process. 
The meeting was held on April 20, 1995, with a written comment period 
extended from May 1 to December 8, 1995.
    On May 31, 1995, the Coast Guard published a notice in the Federal 
Register (60 FR 28376) that stated that the Coast Guard has established 
a goal of eliminating any regulatory differential between requirements 
that apply to U.S. vessels in international trade and those that apply 
to similar vessels in international trade that fly the flag of 
responsible foreign nations. To the maximum extent possible, 
requirements that create an unwarranted differential between U.S. and 
internationally recognized standards will be eliminated. This revision 
of the electrical engineering regulations is, in part, part of this 
project.
    The Coast Guard's electrical safety regulations are based on 
statutory authority provided in 46 U.S. Code (U.S.C.) 3306 and 3703. 
The existing regulations for inspected vessels are contained in chapter 
I, subchapter J, of title 46 of the Code of Federal Regulations (46 CFR 
chapter I, subchapter J). This proposal is mainly concerned with 
changes to this subchapter but associated changes in subchapters I-A 
and Q also are being proposed. All cites in this proposal, unless 
otherwise indicated, are to title 46 CFR.
    This project proposes to revise technical areas of subchapter J to 
address comments received from Coast Guard field and inspection offices 
and the marine industry; to clarify requirements where confusion has 
been shown to exist; to delete or significantly modify obsolete 
requirements; to reflect experiences with vessel reflaggings; and to 
more closely parallel international standards. The revision also 
proposes to incorporate the latest International Convention for the 
Safety of Life at Sea, 1974 (SOLAS 74) amendments (up to and including 
1992), elements of the Coast Guard Regulatory Reform (CGRR) initiative, 
and industry standards.
    The increased frequency of overseas construction of U.S. flag 
vessels has created a need for the Coast Guard to recognize equipment 
designed and installed in accordance with international standards. The 
implementation of SOLAS 74 by the international maritime community has 
promulgated requirements which closely parallel existing Coast Guard 
regulations. Subchapter J will be revised to facilitate U.S. acceptance 
of electrical equipment constructed in accordance with other 
international standards.
    To eliminate needless regulatory burden, the Coast Guard is 
proposing to delete and extensively revise obsolete or confusing 
regulations. For example, the entries for Engine Order Telegraphs are 
proposed to be consolidated and updated. Additionally, the necessary 
degree of safety and reliability for sound powered telephones can be 
maintained with minor additions to subchapter J. This proposal would 
encompass the changes which would make type approval by the Government 
unnecessary. Therefore, in conjunction with these proposed changes, the 
Coast Guard would remove the approval requirement for sound powered 
telephone equipment (now in subchapter Q) and adopt minimum 

[[Page 4133]]
performance requirements in subchapter J. Similar treatment is being 
given Fire Protective Systems. A wide variety of national and 
international standards covering different types of equipment are also 
proposed for incorporation by reference. Also under the proposal, the 
equipment manufacturer would be afforded a choice of Independent 
Laboratories versus the old single-point of testing. Modification of 
current requirements is allowed under existing U.S. statutes, as 46 
U.S.C. 3306 and 3703 provide broad authority to the Secretary to 
prescribe safety regulations. Presently in the regulations, a Fire 
Protection Equipment manufacturer is required to provide a sample of 
its system, built only to the rigid specifications in part 161, subpart 
161.002, to the National Bureau of Standards for testing. The Coast 
Guard would allow equipment to be constructed to several domestic and 
an internationally recognized standards. Also, the Coast Guard 
continues to process applications from a variety of third party testing 
institutions and Commandant (G-MMS) maintains a list at Coast Guard 
headquarters of Independent Laboratories recognized by the Commandant.
    The use of large industrial systems independent of a traditional 
ship's service and propulsion functions are becoming increasingly 
popular. These types of systems provide power to systems that are vital 
to a vessel's mission but not necessarily to its safety. Industrial 
systems would include drilling, manufacturing and scientific research. 
Due to the industrial nature of these systems, it is not necessary for 
them to meet the requirements in subchapter J which are intended to 
provide for reliable ship's service and electrical propulsion systems. 
New requirements, therefore, are being proposed which would permit the 
use of standard industrial equipment without requiring them to meet 
many of the requirements of subchapter J. Electrical installations in 
hazardous locations will continue to meet explosion-proof/
intrinsically-safe requirements. This action serves the needs of 
industry while ensuring a comparable level of safety.
    On November 1, 1974, the Assembly of the International Maritime 
Organization (IMO) adopted the International Convention for the Safety 
of Life at Sea, 1974 (SOLAS 74). To date, IMO has adopted seven sets of 
amendments to the convention pursuant to Article VIII of SOLAS 74. The 
United States has played an instrumental role in the development of the 
Convention and its amendments. As a signatory nation to this 
international treaty, the United States has embraced these amendments 
and periodically upgrades existing regulations, as necessary, to bring 
it into alignment with the SOLAS 74 requirements.
    The Coast Guard's electrical engineering regulations were last 
updated in 1982. In that rulemaking, the Coast Guard reorganized its 
regulations and incorporated the first set of amendments to SOLAS 74. 
This rulemaking proposes incorporating the second through seventh sets 
of amendments to SOLAS 74 (those of 1983, 1988, 1989, 1990, 1991, and 
1992.) In doing so, the Coast Guard inspected vessels' electrical 
safety regulations would be aligned with the international standards 
for safety which are accepted for merchant ships around the world.

Discussion of Proposed Rules

    The proposed revisions to 46 CFR chapter I, subchapter J, would 
clarify and condense, in technically correct language, the Electrical 
Engineering Regulations applicable to U.S. Coast Guard certificated 
vessels. The objective of these revisions is to further reduce the 
regulatory burden on the industry, eliminate misinterpretation of the 
regulations by all affected parties, and bring the regulations in line 
with the state of the art technology in the industry as well as with 
standards accepted by the international maritime community.
    The major changes to subchapter J are discussed below. Other 
changes which are editorial and do not affect the technical content of 
this subchapter are not addressed. The editorial corrections are to 
help the reader understand the intent of the requirements.
    As part of the associated changes, the Coast Guard is also 
proposing to revise 46 CFR 108.170, Definitions, and Sec. 108.181, 
Ventilation for enclosed spaces, to refer to the appropriate sections 
of subchapter J.
    In addition to updating subchapter J to reflect the most recent 
amendments to SOLAS 74, the Coast Guard is also proposing to revise 
subchapter J to incorporate by reference numerous internationally 
recognized marine electrical standards which address construction, 
installation, testing, and safety.

Part 110--General Provisions

    Section 110.01-1. The Coast Guard would revise Sec. 110.1-1, 
General, to add 46 CFR chapter I, subchapter K, Small Passenger Vessels 
Carrying more than 150 Passengers or with Overnight Accommodations for 
more than 49 Passengers, subchapter L, Offshore Supply Vessels, 
subchapter R, Nautical School Vessels, and subchapter W, Lifesaving 
Appliances and Arrangements, to the list of subchapters which require 
electrical installations in accordance with subchapter J. This is not 
additional regulation; but an entry to correct a prior omission such as 
with subchapter R since Sec. 167.40-1(a)(2) already requires such 
compliance; and cross-reference to new subchapters.
    Section 110.01-3. The Coast Guard would revise Sec. 110.01-3, 
Repairs, to address alterations as well as repairs. It is proposed that 
minor alterations on vessels meet the requirements of the regulations 
in effect on the contract date for the original installation, or the 
contract date for the alteration. Unlike minor repairs and alterations, 
major conversions, such as adding a large section to the midbody of the 
vessel or changing the type or size of the main propulsion engine are 
considered, under Coast Guard policy, on a case-by-case basis by 
Commandant (G-MCO). Having a single point of review for these 
situations ensures consistency in application of statutes and 
regulations.
    Section 110.10-1. The Coast Guard would update Sec. 110.10-1, 
Incorporation by reference, to reflect new standards and to update the 
editions of references already incorporated. This section provides the 
addresses of organizations which publish the referenced standards. 
Additionally, the sections affected by the incorporation of standards 
are identified in Sec. 110.10-1.
    Section 110.15-1. The Coast Guard would revise Sec. 110.15-1, 
Definitions, to reflect new and modified terms and definitions used in 
the subchapter. These minor word changes would bring our regulation 
terminology in line with internationally accepted language. The 
proposed changes would remove the reference from ``lifeboats'' and 
replace it with the SOLAS 74 term ``survival craft'' and would replace 
the current definition for dead ship with the SOLAS 74 definition, 
(i.e., remove reference from ``ship service generators'' and replace it 
with ``auxiliaries''). The definition for ``flashpoint'' would be 
revised to reflect the current industry definition. Definitions for 
``waterproof'', ``watertight'', and ``dripproof'' would be modified 
with reference to the text in the National Electrical Manufacturers 
Association (NEMA) and the International Electrotechnical Commission 
(IEC) enclosure categories for the proposed Sec. 111.01-9, Degree of 
protection. Proper training and licensing would be added to the list of 
criteria under the definition for qualified person. This is proposed in 
order to 

[[Page 4134]]
quantify the definition since Certificates of Inspection require a 
vessel to be manned by personnel holding certain licensed and 
unlicensed ratings. Parts 10 and 12 of 46 CFR detail the training, 
experience and testing procedures needed to obtain these licenses and 
documents. On the face of the merchant marine license it states that 
the holder has been duly examined and found competent.
    Section 110.20-1. The Coast Guard would revise Sec. 110.20-1, 
Conditions under which equivalencies may be used, to allow the 
Commanding Officer, Marine Safety Center (MSC) to accept equivalencies 
for fittings, materials, apparatus, equipment, or arrangements required 
by this subchapter. With the consolidation of the Coast Guard's three 
former merchant marine technical offices into one central location, the 
opportunity for different interpretations of equivalencies by different 
Coast Guard offices no longer presents a problem. Allowing the Marine 
Safety Center to accept equivalencies enables the submitter to send all 
plans to one point of contact within the Coast Guard. This procedural 
change would not alter the appeal procedures already contained in 46 
CFR 1.03, Rights of appeal.
    Subpart 110.25. The Coast Guard would revise various paragraphs of 
subpart 110.25, Plan Submittal, to remove Commandant (G-MMS) as one of 
the offices to which plans may be submitted. Commandant (G-MMS) does 
not perform plan review for specific vessels. All vessel plan review is 
now conducted by the U.S. Coast Guard Marine Safety Center (MSC). Also, 
several terms in Sec. 110.25-1(c) will be changed to reflect the 
wording found in SOLAS 74 and other international standards.
    Section 110.30-7. The Coast Guard would revise Sec. 110.30-7, 
Repairs or alterations, to clarify the material. This section 
complements Sec. 110.01-3, Repairs, regarding minor and major repairs 
and alterations. This has been the long-standing regulation in 
subchapter D: 46 CFR 30.01-10, Application of regulations governing 
alterations or repairs. Although the application of these regulations 
has become standard practice for all types of vessels, the Coast Guard 
now proposes to repeat it in the electrical engineering regulation 
subchapter to remove any misunderstanding and clarify that this 
requirement applies to electrical systems on all vessels subject to 
subchapter J.
    Subpart 110.35. The Coast Guard would add a new subpart 110.35, 
Independent Laboratories, which would define Independent Laboratories. 
An Independent Laboratory will be a laboratory which has been accepted 
by the Commandant under part 159 of this chapter for the testing of 
electrical and electronic equipment and other related apparatus. 
Paragraph (j) of Sec. 110.25-1 would be changed to refer to an 
Independent Laboratory instead of specifically named laboratories.

Part 111--Electric Systems--General Requirements

    Section 111.01-5. The Coast Guard would add electrical cable to the 
list of equipment in Sec. 111.01-5, Protection from bilge water. In 
addition to being sound engineering practice, the American Bureau of 
Shipping (ABS) Rules for Building and Classing Steel Vessels prohibit 
generator cable installation in the bilge and the Institute of 
Electrical and Electronic Engineers (IEEE) Standard 45 (Recommended 
Practice for Electric Installations on Shipboard) recommend not 
installing any cable in the bilge.
    Section 111.01-7. The Coast Guard would revise Sec. 111.01-7, 
Accessibility, to remove specific references, throughout the 
subchapter, to detailed construction requirements. A new paragraph (b) 
would be added which would provide general performance and safety 
guidelines. These revisions would set standards for equipment based on 
performance criteria and therefore allow the removal of more detailed 
construction specifications.
    Section 111.01-9. The Coast Guard would change the title of 
Sec. 111.01-9, Watertight, waterproof, and dripproof equipment, to 
Degrees of protection, and revise the section to reflect the revision 
of Sec. 110.15-1, Definitions. These changes now bring the regulations 
on enclosures in line with IEC standards while allowing the option of 
National Electrical Manufacturers Association (NEMA) enclosure 
selection.
    Section 111.01-15. The Coast Guard would revise Sec. 111.01-15, 
Temperature ratings, to require an ambient temperature of 45  deg.C for 
most electrical equipment in machinery spaces instead of the currently 
required 50  deg.C. The international community has established 45 
deg.C as the standard ambient temperature for these shipboard 
applications. Rotating machinery would still be required to be rated 
for 50  deg.C because of its inherent heating characteristics, but 
cable installed in machinery spaces would be rated at 45  deg.C. 
Control and instrumentation equipment would be rated at 55  deg.C in 
order to comply with the international requirements. The proposed 
changes would still allow for derating equipment based on the actual 
ambient temperature of the space.
    Section 111.01-17. The Coast Guard would revise Sec. 111.01-17, 
Nature of electric supply, by renaming the section, Voltage and 
frequency variations, and deleting specific reference to restrictive 
standard voltages and frequency as well as deleting table 111.01-17(b), 
Standard Voltages. The revision would instead reference industry 
standard operating parameters for electrical machines and apparatus.
    Sections 111.01-19, 111.01-21, and 111.01-23. The Coast Guard would 
add three new sections: Sec. 111.01-19, Inclination of the ship, 
Sec. 111.01-21, Vibration, and Sec. 111.01-23, Humidity. These sections 
would include requirements for the electrical systems in relation to 
the inclination of a vessel and those for conditions of vibration and 
humidity.
    Section 111.05-1. The Coast Guard would revise Sec. 111.05-1, 
Purpose, with a minor addition to include ``systems'' as stated in the 
subpart title.
    Section 111.05-07. The Coast Guard would revise Sec. 111.05-7, 
Armored and metallic-sheathed cable, in order to align installation 
requirements of armor sheathed cable with international standards.
    Section 111.05-9. The Coast Guard would revise Sec. 111.05-9, 
Masts, to address lightning protection for vessels with nonmetallic 
masts. This proposed revision would account for the expanded use of 
lighter weight composite materials for masts.
    Section 111.05-19. The Coast Guard would revise Sec. 111.05-19, 
Tank vessels; grounded distribution systems, to align the systems' 
voltage limits with the IEC (1000 volts) vice 3000 volts currently 
mandated in the regulations. This gives the designer of nominal 2400 
volt plants the option of a grounded distribution system.
    Section 111.05-23. The Coast Guard would revise Sec. 111.05-23, 
Location of ground indicators, to include requirements for branch 
circuit detection indicators where the circuit is isolated from the 
main source by a transformer or other device. Normal ground detector 
indication at the distribution switchboard is required in paragraph (a) 
for conventional feeder circuits. This proposal extends indication 
coverage to the load side of isolation devices whose circuits would not 
be otherwise monitored. Also, this proposal brings to one central 
location all ground detection device requirements and relieves the 
engineer of the burden, especially in an emergency, of visiting each 
transformer 

[[Page 4135]]
or isolation device to ascertain the ground condition of the branch 
circuit.
    Sections 111.05-25, 111.05-27, and 111.05-29. The Coast Guard would 
revise Sec. 111.05-25, Ungrounded systems, Sec. 111.05-27, Grounded 
neutral alternating-current systems, and Sec. 111.05-29, Dual voltage 
direct-current systems, to offer a greater number of options in ground 
detection circuitry. The proposed revision would remove restrictive 
wattage and current limitations on detection circuit components thereby 
allowing for innovative design and would replace them with performance 
parameters.
    Section 111.05-33. The Coast Guard would revise Sec. 111.05-33, 
Equipment grounding conductors, to require that each equipment 
grounding conductor be insulated and be of a size at least equal to 
current carrying conductor. This proposal would align our regulations 
with the National Electrical Code (NEC).
    Sections 111.05-37 and 111.05-39. The Coast Guard would consolidate 
Sec. 111.05-39, Switches and circuit breakers, into Sec. 111.05-37, 
Overcurrent device. Both sections presently address overcurrent 
protection devices.
    Section 111.10-1. The Coast Guard would revise paragraph (a) of 
Sec. 111.10-1, Definitions, to remove certain cargo refrigeration 
systems from the list of ship's service electrical loads. These loads 
are industrial in nature and are not directly related to the safety of 
the vessel. These refrigeration systems are added to the list of 
industrial type loads in the same section.
    Section 111.10-3. The Coast Guard would revise Sec. 111.10-3, Two 
generating sets, to add the requirement that a Mobile Offshore Drilling 
Unit (MODU) must have at least two ship's service generating sets. This 
is presently a requirement of the International Maritime Organization 
(IMO) MODU Code. The Coast Guard proposes the inclusion since 
subchapter I-A for MODU Inspection and Certification references 
subchapter J for their electrical systems.
    Section 111.10-4. The Coast Guard would revise Sec. 111.10-4, Power 
requirements; generating sets, to define the required generating 
capacity. The changes would result in regulations which mirror the 
requirements of SOLAS 74. The Coast Guard would revise paragraph (b) to 
clarify the fact that the capacity of the ship's service generating set 
or sets must be sufficient to carry the ship's service loads with the 
largest ship's service generator stopped. The Coast Guard would revised 
paragraph (d) to ensure that propulsion-plant loads do not impact on 
ship's service loads when these loads are supplied by a common 
generator. New paragraphs (e) and (f) would be added specifically to 
address main-engine-dependent generators. The proposed regulation 
reflects a harmonization with international standards, recognized 
classification society requirements, and present industry practice for 
these types of generators.
    Section 111.10-7. The Coast Guard would revised paragraph (b) of 
Sec. 111.10-7, Dead ship, by adding a sentence referencing additional 
existing requirements contained in Sec. 112.05-3 of this chapter. These 
requirements refer to the main and emergency bus-tie.
    Sections 111.10-9 and 111.10-11. The Coast Guard would revise 
Sec. 111.10-9, Ship's service supply transformers; 2 required, to 
clarify the intent of the requirement and bring the requirements of 
Sec. 111.10-11, Power requirements; transformers under this one 
section.
    Section 111.12-1. The Coast Guard would revised paragraph (a) of 
Sec. 111.12-1, Prime movers, to incorporate American Bureau of Shipping 
(ABS) Rules for prime movers, paragraph (b) to clarify that all 
generator prime movers need a governor, and paragraph (c) to remove the 
exemption from the automatic shut down in case of loss of lubricating 
oil.
    Section 111.12-5. The Coast Guard would revise paragraph (a) of 
Sec. 111.12-5, Generator construction and testing, to reflect a change 
in the ABS Rules numbering system and would remove the designation 
``(a)'' from the paragraph. Paragraphs (b), (c), and (d) would be 
removed.
    Section 111.12-7. The Coast Guard would revise paragraph (a) of 
Sec. 111.12-7, Voltage regulation and parallel operation, to reflect a 
change in ABS Rules numbering system.
    Sections 111.15-1, 111.15-2, and 111.15-3. The Coast Guard would 
revise Sec. 111.15-1, General Sec. 111.15-2, Battery construction, and 
Sec. 111.15-3, Battery categories, to eliminate restrictive 
construction details and to allow the use of different types of 
batteries, including sealed batteries and other designs. The specific 
size requirement in paragraph (c) of Sec. 111.15-2 would be removed and 
reclassification would be allowed under paragraph (d) of Sec. 111.15-3. 
Additionally, the Coast Guard proposes a new paragraph (d) in 
Sec. 111.15-2 be added as a performance measure to address a battery's 
suitability for installation in the marine environment.
    Section 111.15-5. The Coast Guard would revised paragraph (a) in 
Sec. 111.15-5, Battery installations, by deleting the reference to 
specific test laboratories. All electrical equipment and laboratory 
testing requirements for hazardous locations would be addressed in 
subpart 111.105, Hazardous Locations. Additionally, the Coast Guard 
would allow for the expanded use of internationally available 
electrical equipment by providing reference to IEC hazardous location 
classifications. The Coast Guard would amend Sec. 111.15-5(c), Small 
batteries, to allow liberal storage of small-size sealed batteries. 
This is possible due to the reduced hazard associated with sealed 
equipment. The Coast Guard would eliminate paragraph 111.15-5(e), 
Tiers. This requirement is redundant with the spacing requirement 
specified in paragraph 111.15-5(d), Battery trays. The remaining 
paragraphs (f), (g) and (h) would be renamed (e), (f) and (g).
    Section 111.15-10. The Coast Guard would revise paragraph (g) of 
Sec. 111.15-10, Ventilation, to explain the intent of ventilation 
requirements for small battery installations. If the battery box were 
in a non-environmentally-controlled location, simple vent openings may 
allow the ingress of water. A statement on preventing ingress would be 
added.
    Section 111.15-20. The Coast Guard would revise Sec. 111.15-20, 
Conductors, to put the accepted installation practices presently 
included in this section into proper terminology. The requirements in 
paragraphs (b) and (c) would be combined into one paragraph.
    Section 111.15-30. The Coast Guard would revise Sec. 111.15-30, 
Battery chargers, to eliminate specific construction requirements for 
battery chargers. In their place, the Coast Guard proposes certain 
performance requirements.
    Section 111.20-1. The Coast Guard would revise Sec. 111.20-1, 
General requirements, to reflect internationally accepted practices for 
transformer construction, installation and protection by allowing not 
only the winding but also the enclosure to provide the necessary 
protection.
    Section 111.20-15. The Coast Guard would revise Sec. 111.20-15, 
Transformer overcurrent protection, to reflect internationally accepted 
practices for transformer overcurrent protection by allowing a choice 
of standards.
    Section 111.25-5. The Coast Guard would revise paragraph (a) of 
Sec. 111.25-5, Marking, to allow nameplate markings in accordance with 
the practices of the IEC as an alternative to the present National 
Electrical Code requirement.
    Section 111.30-1. The Coast Guard would revise Sec. 111.30-1, 
Location and installation, to require switchboard installation to 
follow industry practice by removing specific construction 

[[Page 4136]]
detailed regulatory language and instead referring to the appropriate 
guidance of IEEE Standard 45.
    Section 111.30-4. The Coast Guard would revise Sec. 111.30-4, 
Circuit breakers removable from front, to allow an alternative method 
of circuit breaker installation. This would permit the circuit breaker 
to be hard-wired to the switchboard if: (1) The switchboard is divided 
into two or more sections that can be split by disconnecting a link 
between a section of the switchboard, and (2) the connection of 
generators and duplicated equipment is equalized between the sections 
of the main bus. This allows for the capability of de-energizing a 
section of the switchboard without shutting down the power supply or 
degrading the continuity of power supply to vital loads.
    Section 111.30-5. The Coast Guard would revise Sec. 111.30-5, 
Construction, to remove detailed switchboard construction requirements 
and incorporate international consensus standards (IEEE Standard 45 and 
IEC Publications 92-302/92-503).
    Sections 111.30-9, 111.30-11, and 111.30-13. The Coast Guard would 
eliminate Sec. 111.30-9, Mechanical protection, Sec. 111.30-11, Mats or 
gratings, and Sec. 111.30-13, Grounding. The requirements of these 
sections are included in the industry practices of the IEEE Standard 45 
and the IEC Publications.
    Section 111.30.-19. The Coast Guard would revise Sec. 111.30-19 
Buses and wiring. Paragraph (a) would be revised to allow for the 
guidance of international performance standards instead of the present 
detailed technical requirements. Paragraphs (b) through (e) would be 
deleted because the information they contain is covered by proposed 
paragraph (a). Paragraph (f) would be renamed paragraph (b) and would 
be revised to allow for the use of small-conductor-size cable, such as 
ribbon cable, for instrumentation and control circuitry, as is common 
industry practice.
    Section 111.30-21. The Coast Guard would eliminate Sec. 111.30-21, 
High temperature devices. This design specification would be addressed 
in the requirements of the appropriate industry standards of the IEEE 
and IEC and need not be repeated here.
    Section 111.30-23. The Coast Guard would eliminate Sec. 111.30-23, 
Medium voltage switchboards. These requirements will be part of the 
proposed revision of Sec. 111.30-5, Construction.
    Section 111.30-24. The Coast Guard would revise Sec. 111.30-24, 
Generation systems greater than 3000 kw, to modify the exemption for 
MODUs to split the switchboard when the total generator power exceeds 
3000 kw. The IMO MODU Code requires self-propelled MODUs to have a 
split switchboard when the total installed generator capacity exceeds 3 
Megawatts (3000 kw). Therefore the exemption will apply only to 
nonself-propelled MODUs.
    Section 111.30-29. The Coast Guard would revise Sec. 111.30-29, 
Emergency switchboards, by adding paragraphs (g), (h) and (i). These 
paragraphs are presently contained in part 112. The purpose of this 
change is to consolidate all of the requirements for the emergency-
switchboard instrumentation and equipment into one section.
    Section 111.30-31. The Coast Guard would delete Sec. 111.30-31, 
Tests. Presently this section requires switchboards to be tested to an 
American Bureau of Shipping requirements. American Bureau of Shipping 
Rules do not address the testing of switchboards.
    Section 111.33-3. The Coast Guard would replace the descriptive 
nameplate requirements of Sec. 111.33-3, Nameplate data, for 
semiconductor rectifier systems with industry practice according to 
international standards.
    Section 111.33-5. The Coast Guard would replace the descriptive 
installation requirements of Sec. 111.33-5, Installation, for 
semiconductor rectifier systems with industry practice according to 
international standards.
    Section 111.33-11. The Coast Guard would revise Sec. 111.33-11, 
Propulsion systems, to reflect the current American Bureau of Shipping 
numbering system regarding semiconductor rectifier systems.
    Section 111.35-1. The Coast Guard would revise Sec. 111.35-1, 
Electrical propulsion installations, to reflect the current American 
Bureau of Shipping numbering system.
    Section 111.40-1, 111.40-5, and 111.40-7. The Coast Guard would 
remove Sec. 111.40-1, Panelboard, standard, to eliminate the 
requirement of meeting a specific standard and thereby allowing the use 
of panelboards which are designed and constructed according to sound 
engineering practice. Likewise, the Coast Guard would revise 
Sec. 111.40-5, Enclosure, and Sec. 111.40-7, Location, to allow the 
installation of panelboards with a suitable degree of protection to be 
installed in the weather. This change allows more latitude in the 
electrical arrangement on the ship without reducing personnel safety 
requirements.
    Section 111.50-2. The Coast Guard would add a new Sec. 111.50-2, 
Systems integration. This new section would reflect the need to 
consider component compatibility within each overcurrent protection 
system.
    Section 111.50-3. The Coast Guard would revise paragraphs (c), (d), 
(f) and (h)(2) of Sec. 111.50-3, Protection of conductors, to allow the 
use and incorporate the requirements of the IEC for fuses, circuit 
breakers, thermal devices and ground conductors.
    Section 111.52-1. The Coast Guard would correct Sec. 111.52-1, 
General, to identify the physical unit (i.e., ``current'') needed to be 
calculated when performing short-circuit current calculations.
    Section 111.52-5. The Coast Guard would revise Sec. 111.52-5, 
Systems 1500 kilowatts or above, to allow several additional methods of 
short-circuit current calculations. This would ensure that the 
appropriate method of short-circuit current calculation is available to 
the designer as well as the plan reviewer.
    Section 111.53-1. The Coast Guard would revise paragraph (a)(1) of 
Sec. 111.53-1, General, to eliminate specific reference to parts E and 
F of the National Electrical Code relative to fuses. The revision would 
add the option of meeting the general provisions of IEC internationally 
recognized standards. Additionally, the Coast Guard would revise 
paragraph (a)(3) to eliminate restrictive reference to Underwriters 
Laboratories, Inc. This would expand industry's options to list fuses 
with any Independent Laboratory. The Coast Guard would revise paragraph 
(b) to eliminate prohibitive reference to Edison-base fuses. The Coast 
Guard recognizes that systems designed and built to IEC and/or CEN 
standards may contain these fuses. It is also recognized that many 
Maritime Administration (MARAD) Ready Reserve Force reflagged vessels 
have been operating with such equipment for years. The Coast Guard, 
however, maintains its prohibition of renewable-link cartridge fuses 
because it is considered a severe safety hazard in that a link of a 
higher than recommended current value might be placed in a jacket 
marked with a lower value and the fault be undetectable. The Coast 
Guard would add a new paragraph (c) to provide for the ability to test 
for fuse condition, particularly for installations utilizing Edison-
base fuses, since the glass or plastic link protector inhibits the 
readily available test points offered by a more common cartridge fuse.
    Section 111.54-1. The Coast Guard would revise Sec. 111.54-1, 
Circuit breakers, to include reference to and the allowance of 
internationally recognized standards and at the same time 

[[Page 4137]]
eliminate reference to restrictive and specific construction standards.
    Section 111.55-1, 111.55-5, 111.55-7, and 111.55-9. The Coast Guard 
would delete Sec. 111.55-5, Knife switches, Sec. 111.55-7, Snap 
switches, and Sec. 111.55-9, Enclosed switches. These requirements do 
not provide an additional level of safety beyond that ensured by 
compliance with Sec. 111.55-1, General.
    Subpart 111.57. The Coast Guard would eliminate subpart 111.57, 
Current-Limiting Devices. The operating and design characteristics of 
current limiting devices would be included in the revision of subpart 
111.53, Fuses, and subpart 111.54, Circuit Breakers. This, in turn, 
reduces repetitive and unnecessary regulation.
    Section 111.59-1. The Coast Guard would rewrite Sec. 111.59-1, 
General, to eliminate paragraph (b) and the requirement that busways 
meet a specific construction standard, as the performance of the 
component is established by compliance with paragraph (a).
    Section 111.59-3. The Coast Guard would revise Sec. 111.59-3, No 
mechanical cooling, to correct an omission. In the present version, the 
regulations state that ``A busway must need mechanical cooling * * *'' 
which is opposite to the intent of this section.
    Section 111.60-1. The Coast Guard would revise Sec. 111.60-1, Cable 
construction and testing, to align our regulation language with that of 
the 1983 edition of IEEE Standard 45. Additionally, the Coast Guard 
would propose to include, as acceptable, cable that is designed, 
constructed, tested and installed in accordance with the international 
standards of IEC Publications 92-3 and certain 92-350 series as well as 
several MIL Specification cables.
    Sections 111.60-2 and 111.60-6. The Coast Guard would add new 
Sec. 111.60-2, Specialty cable for communication and RF applications, 
and Sec. 111.60-6, Fiber optic cable, to include requirements for 
specialty electrical cables and optical fiber cables. The proposed 
requirements address installation and flammability characteristics for 
these cables. The Coast Guard feels this is necessary because of the 
present lack of guidance for this relatively new equipment now on board 
or contemplated for installation on board certificated vessels and 
because of the larger fire load the cable represents.
    Section 111.60-3. The Coast Guard would revise Sec. 111.60-3, Cable 
application, to include the applicable requirements of IEC Publication 
352 and to assure proper derating of cables according to type 
construction.
    Section 111.60-4. The Coast Guard would revise Sec. 111.60-4, 
Minimum cable conductor size, to include instrumentation cable with the 
thermocouple and pyrometer group. Mention of general instrumentation 
cable was unintentionally omitted from the regulations during the last 
revision.
    Section 111.60-5. The Coast Guard would revise Sec. 111.60-5, Cable 
installation, to include reference to the installation of cables 
constructed in accordance with the international standard IEC 
Publication 92-3 and the IEC 92-350 series.
    Section 111.60-11. The Coast Guard would revise Sec. 111.60-11, 
Wire, to expand the choices available for shipboard wiring. The current 
requirements are too restrictive and do not constitute an appreciable 
increase in safety beyond the proposed reduction in those requirements.
    Section 111.60-13. The Coast Guard would revise paragraph (a) of 
Sec. 111.60-13, Flexible electric cord and cables, to remove the 
restrictions presently governing the use of flexible cord and cables. 
The proposed change allows compliance with a larger number of 
nationally-recognized standards.
    Section 111.60-17. The Coast Guard would revise Sec. 111.60-17, 
Connections and terminations. The current regulations are merely a 
narrative describing standard marine practice. The proposed revision 
would outline specific installation criteria for connectors and 
terminals.
    Section 111.60-19. The Coast Guard would revise Sec. 111.60-19, 
Cable splices, to reflect current industry practice as outlined in the 
internationally accepted IEEE Standard 45.
    Section 111.60-21. The Coast Guard would revise Sec. 111.60-21, 
Cable insulation tests, to reflect a change in numbering system of the 
referenced IEEE standard.
    Section 111.60-23. The Coast Guard would add a new Sec. 111.60-23, 
Type MC cable, to address the lack of requirements primarily on 
offshore production platforms. However, the installation of this cable 
is not limited to offshore platform applications and may be used as 
shipboard cable provided certain installation requirements are 
followed.
    Subpart 111.70. The Coast Guard would revise subpart 111.70, Motor 
Circuits, Controllers and Protection, to reflect internationally 
recognized classification society standards, practices and requirements 
which do not rely solely on the shoreside code of the National 
Electrical Code. Additionally, the revision will eliminate obsolete 
requirements.
    Section 111.75-1. The Coast Guard would revise paragraph (a) of 
Sec. 111.75-1, Lighting feeders, to replace the term ``fire screen'' 
with the term ``fire'' to agree with SOLAS 74, and include reference to 
low location egress lighting. The Coast Guard would eliminate paragraph 
(c). This requirement does not elevate the overall safety level of the 
vessel. The Note, however, is part of the section and is retained.
    Section 111.75-5. The Coast Guard would delete the voltage specific 
requirements of lighting circuits by deleting paragraph (b), Voltages, 
in Sec. 111.75-5, Lighting branch circuits, and the remaining 
paragraphs would be re-lettered and re-numbered accordingly. The Coast 
Guard would redesignate paragraph (c), Connected load, as paragraph (b) 
and revise the narrative concerning connected loads. The removed 
narrative is standard electrical practice and need not be specified in 
the regulations. The Coast Guard would redesignate paragraph (e), 
overcurrent protection, as paragraph (d), redesignate paragraph (f), 25 
or 30 ampere lighting branch circuits, as paragraph (e), and revise the 
new paragraph (d) to remove the specifications for the minimum 
conductor sizes. The requirements for these loads required by proposed 
revisions of Sec. 111.60-3, Cable application, and Sec. 111.60-4, 
Minimum cable conductor size, are adequate. The Coast Guard would 
eliminate paragraph (g), connections to screw-shell lampholders, as it 
is considered standard practice and need not appear in regulation.
    Section 111.75-15. The Coast Guard would revise paragraph (c), 
Illumination of passenger and crew spaces, in Sec. 111.75-15 to 
eliminate restrictive wording and replace this requirement with a 
performance requirement concerning normal habitability and safe egress 
under emergency conditions.
    Section 111.75-16. The Coast Guard would revise Sec. 111.75-16, 
Lifeboat and liferaft floodlights, to replace the terms ``lifeboat'' 
and ``liferaft'' with the term ``survival craft'' to agree with SOLAS 
74 terminology.
    Section 111.75-17. The Coast Guard would delete paragraph (d)(1) of 
Sec. 111.75-17, Navigation lights, which requires navigation light 
fixtures to be approved by the Commandant, as this would no longer be 
required. The Coast Guard proposes instead that paragraph (d) be 
further revised to incorporate labeling requirements to show compliance 
with UL 1104 by an Independent Laboratory. The Coast 

[[Page 4138]]
Guard would delete paragraph (f), Light screens. This requirement is 
clearly stated in the COLREGS Annex I Rule 5 and in 33 U.S.C. 1602 and 
need not be repeated here.
    Section 111.75-18. The Coast Guard would revise Sec. 111.75-18, 
Signaling lights, to reflect SOLAS 74 Regulation V/11 for applicability 
and to reduce specific construction details.
    Section 111.75-20. The Coast Guard would revise Sec. 111.75-20, 
Lighting fixtures, to modify paragraph (a) to include UL's deleting UL 
595 (Marine-Type Electric Lighting Fixtures) and incorporating specific 
Marine requirements into the respective fixture type standards (i.e., 
UL 1570 is for Fluorescent Lighting Fixtures, UL 1571 is for 
Incandescent Lighting Fixtures, etc.). Also, the Coast Guard would add 
an additional paragraph (e) which would address the installation of 
non-emergency interior and decorative lighting in environmentally-
controlled spaces. Also, requirements related to shock and vibration 
which may be encountered in the marine environment will be addressed. 
Both paragraphs will reference additional international standard 
options.
    Sections 111.77-3, 111.77-5, 111.77-7, 111.77-9, and 111.77-11. The 
Coast Guard would eliminate Sec. 111.77-3, Electric cooking equipment, 
Sec. 111.77-5, Electric motor-operated appliances, Sec. 111.77-7, 
Dishwashers, Sec. 111.77-9, Refrigerators, and Sec. 111.77-11, 
Refrigerated drinking water coolers, and replace them with 
internationally recognized safety standards. Selection of safe 
appliances, based on industry construction and testing standards for 
use on commercial vessels, is at the option of the vessel owner.
    Section 111.79-1. The Coast Guard would revise Sec. 111.79-1, 
Receptacle outlets; general, to remove specific construction 
requirements and to allow for more flexibility in installations.
    Section 111.79-5. The Coast Guard would eliminate Sec. 111.79-5, 
Damp or wet locations and weather locations, and incorporate more 
general industry standards and practices under Sec. 111.79-1, 
Receptacle outlets; general, in the proposed revision of paragraphs (c) 
and (d).
    Section 111.79-7. The Coast Guard would remove the detailed 
construction requirements for receptacle components in Sec. 111.79-7, 
No live parts, and replace them with performance requirements.
    Section 111.79-13. The Coast Guard would revise and rename 
Sec. 111.79-13, Different potentials on a vessel, to read, Different 
voltages and power types, to remove any ambiguity and more clearly 
explain the intent of the regulation.
    Sections 111.81-1 and 111.81-5. The Coast Guard would delete 
Sec. 111.81-5, National Electrical Code, and the text, which addresses 
the NEC requirements for outlet boxes and junction boxes, would be 
relocated to new paragraph (d) in Sec. 111.81-1, Outlet boxes and 
junction boxes: General. The new Sec. 111.81-1(d) would address the 
general requirements for junction boxes in terms of U.S. national 
standards and introduce the option of international standards as well. 
This change would also consolidate the requirements for junction boxes 
into one section.
    Section 111.81-7. The Coast Guard would rename Sec. 111.81-7, 
Degree of protection. The Coast Guard would also propose to revise this 
section by incorporating industry accepted standards and terminology, 
both domestic and international.
    Section 111.81-9. The Coast Guard would revise Sec. 111.81-9, 
Mounting, to remove specific installation restrictions and replace them 
with performance requirements.
    Section 111.81-11. The Coast Guard would eliminate Sec. 111.81-11, 
Penetration of walls. This regulation is unnecessary since, by 
definition, a watertight enclosure must retain its integrity to be 
considered watertight.
    Section 111.81-13. The Coast Guard would eliminate Sec. 111.81-13, 
Construction. General construction requirements for outlet and junction 
boxes are now addressed in proposed paragraphs 111.81-7(a) and (b).
    Section 111.83-3. The Coast Guard would remove Sec. 111.83-3, 
Spacing: Live parts and live parts and ground, as the subject is 
addressed in Sec. 111.01-7, Accessibility.
    Subpart 111.85. The Coast Guard would revise subpart 111.85, 
Electric Oil Immersion Heaters, to exempt oil immersion heaters where 
it can be shown that the operating temperature of the heater can never 
reach the ignition temperature of the oil or vapor with which it is in 
contact.
    Section 111.87-3. The Coast Guard would revise paragraph (a) of 
Sec. 111.87-3, General requirements, to remove construction 
requirements to specific standards and replace them with reference to 
more general safety related requirements.
    Subpart 111.89. The Coast Guard would eliminate subpart 111.89, 
Motion Picture Projectors. This regulation references a standard that 
is no longer pertinent to the marine environment. State-of-the-art 
technology has substituted video tape and laser disk players which do 
not present the same level of risk as projectors.
    Section 111.91-1. The Coast Guard would revise and rename 
Sec. 111.91-1, Control and interlock circuits, to require elevator and 
dumbwaiter power, control, interlock, and switch circuitry to meet the 
requirements of American National Standards Institute, Inc. (ANSI 
A17.1).
    Section 111.91-3. The Coast Guard would eliminate Sec. 111.91-3, 
Control switches. This design standard is not pertinent to the 
performance of the device.
    Section 111.95-3. The Coast Guard would eliminate the detailed 
construction requirements of paragraphs (a) through (e) of Sec. 111.95-
3, General requirements. Paragraph (f) would be renamed (b) and 
retained. New general requirements will be set forth in a proposed 
revision to reference industry accepted standards (both national and 
international) and other proposed requirements for Degree of Protection 
and Accessibility.
    Section 111.95-5. The Coast Guard would eliminate the detailed 
requirements of Sec. 111.95-5, Detail construction requirements. 
Sufficient guidance is afforded in the proposed revision of Sec. 111-
95-3, General requirements.
    Section 111.95-7. The Coast Guard would delete figures 111.95-7 
(e)(1) through (e)(5), which address typical boat winch wiring diagrams 
and arrangement drawings. The figures create confusion in the 
application of lifeboat davit switches and serve no useful or safety 
purpose.
    Section 111.97-5. The Coast Guard would revise paragraph (c) of 
Sec. 111.97-5, Electric and hydraulic power supply, to reduce the 
required capacity of an accumulator tank on a hydraulic system common 
to more than one power-operated watertight door. The present regulation 
requires the tank to have sufficient capacity to open and close all 
doors three times. Consistent with SOLAS 74, the proposed requirement 
states that the capacity must be sufficient to close all doors two 
times and open all doors once.
    Subpart 111.99. The Coast Guard would revise subpart 111.99, 
Firescreen Door Holding and Release Systems, to replace the term ``fire 
screen'' with the term ``fire'' to provide consistency with the 
terminology of SOLAS 74, Regulation II-2/47.
    Section 111.99-1. The Coast Guard would expand the scope of 
Sec. 111.99-1, Applicability, to address fire doors installed on all 
vessels which require fire doors. The subchapters in 46 CFR containing 
requirements for specific vessel types all require fire doors to meet 
subpart 111.99.

[[Page 4139]]

    Subpart 111.105. The Coast Guard would add, delete and revise 
sections of subpart 111.105, Hazardous Locations, to reflect current 
national standards and recognized classification society rules. 
Additionally, means of alternative compliance to these particulars will 
be provided by incorporating by reference international standards 
(i.e., IEC, CEN and IEEE). Specific paragraphs and sections affected 
follow.
    Section 111.105-1. The Coast Guard would revise Sec. 111.105-1, 
Applicability, to remove the restriction to the National Electrical 
Code references to hazardous locations and provide options from IEC 
Publication 79 series.
    Section 111.105-3. The Coast Guard would add a new Sec. 111.105-3, 
General requirements, to provide basic guidance to hazardous location 
information and to set forth the appropriate standards.
    Section 111.105-5. The Coast Guard would rename the section and 
delete the subject material of Sec. 111.105-5, National Electrical 
Code, whose guidance has been superseded by proposed new Sec. 111.105-
3. Proposed Sec. 111.105-5, System integrity, would now address the 
prohibition of mixing the requirements of the NEC with IEC equipment 
and systems since, although equivalent in level of safety, they differ 
in the manner by which this is achieved.
    Section 111.105-7, 111.105-9, 111.105-11, and 111.105-23. The Coast 
Guard would revise Sec. 111.105-7, Approved equipment, Sec. 111.105-9, 
Explosionproof equipment, Sec. 111.105-11, Intrinsically safe systems, 
and Sec. 111.105-23, Fan motors, to replace the specifically mentioned 
test facilities with phraseology that will provide industry with a 
greater number of options for product testing.
    Section 111.105-10. The Coast Guard would eliminate Sec. 111.105-
10, Purged and pressurized equipment. Its content, with options, would 
be sufficiently presented in proposed Sec. 111.105-7, Approved 
equipment.
    Section 111.105-11. The Coast Guard would revise paragraph (a) of 
Sec. 111.105-11, Intrinsically safe systems, to remove the restriction 
of specific test laboratories and to add additional accepted 
international standards to which equipment may be tested.
    Section 111.105-11. The Coast Guard would add paragraphs (b)(3) and 
(b)(4) in Sec. 111.105-11, Intrinsically safe systems, as an additional 
safety measure and to conform with accepted industry practices as 
stated in the IEEE Standard 45. Also, the requirements in Sec. 111.105-
11(e) are to be relocated to proposed Sec. 110.25-1(c)(12) to 
consolidate the requirements relating to plan submittal.
    Sections 111.105-15 and 111.105-17. The Coast Guard would delete 
Sec. 111.105-15, Wiring methods for Class I hazardous locations, and 
Sec. 111.105-17, Wiring methods for Class II and Class III hazardous 
locations. A new Sec. 111.105-15 entitled, Additional methods of 
protection, and a new Sec. 111.105-17 entitled, Wiring methods for 
hazardous locations, are proposed. These would permit the use of 
conduit systems as allowed by the National Electrical Code and afford a 
greater variety of equipment complying with internationally accepted 
standards.
    Section 111.105-19. The Coast Guard would revise Sec. 111.150-19, 
Switches, to conform with reference to proposed revisions which reflect 
the acceptance of equipment meeting international standards.
    Sections 111.105-21, 111.105-23, and 111.105-25. The Coast Guard 
would revise the title and text of Sec. 111.105-21, Fans, to 
consolidate the guidance in Sec. 111.105-23, Fan motors, and 
Sec. 111.105-25, Ventilation ducts, thereby eliminating those two 
sections.
    Section 111.105-29. The Coast Guard would revise paragraph (a) In 
Sec. 111.105-29, Combustible liquid cargo carriers, to include 
requirements for submersible pumps on vessels with combustible liquid 
cargoes having flashpoints 60  deg.C or higher. This reflects the 
requirements of the International Code for the Construction and 
Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code), 
which allows for submersible cargo pumps to be used on vessels with a 
cargo having a flashpoint exceeding 60  deg.C. The Coast Guard would 
add paragraph (c) to include hazardous area classification requirements 
for vessels carrying a cargo with a flashpoint of 60  deg.C or higher 
which is heated to within 15  deg.C of its flashpoint. This reflects 
the requirements of the IBC Code.
    Section 111.105-31. The Coast Guard would revise Sec. 111.105-31, 
Flammable or combustible cargo with a flashpoint below 60 degrees C 
(140 degrees F), liquid sulfur and inorganic acid carriers, to include 
information in agreement with the wording and guidance in 33.14 
(Electrical Installations on Tank Vessels) of IEEE Standard 45. The 
Coast Guard would revise paragraph (e) to include internationally 
accepted terminology of the IEC concerning zone descriptions of 
hazardous locations. The Coast Guard would revise paragraph (l) by 
adding new paragraphs (l)(3) and (l)(4) to include requirements for 
electrical installations in hazardous locations on board vessels with 
cargoes with flashprints below 60  deg.C in accordance with 
international standards.
    Section 111.105-32. The Coast Guard would revise the title of 
Sec. 111.105-32, Bulk liquefied gas and ammonia carriers, and paragraph 
(e), which addresses the requirements for submersible cargo pumps in 
bulk liquefied flammable gas and ammonia carriers, and would reference 
the requirements of Sec. 111.105-31(d) for submersible pumps.
    Section 111.105-35. Presently, when a vessel is issued a 
Certificate of Inspection to carry coal, the certificate does not 
differentiate between the types of coal. This allows a vessel to carry 
both types, bituminous and anthracite coal. The Coast Guard would 
revise Sec. 111.105-35 to require that vessels carrying coal of any 
type be subject to the same hazardous area classification requirements. 
Therefore, the vessel's hazardous area plan should address the worst 
case scenario.
    Section 111.105-37. The Coast Guard would revise Sec. 111.105-37, 
Flammable anesthetics, to reflect a change in name and number of the 
referenced NFPA standard.
    Section 111.105-39. The Coast Guard would revise and rename 
Sec. 111.105-39, Gasoline or other highly volatile motor fuel carried 
in vehicles, to reflect current recognized classification society rules 
regarding requirements for vessels carrying vehicles with fuel in their 
tanks. Additionally, means of alternative compliance to classification 
society rules is provided by citing IEC Zone classification.
    Section 111.105-40. The Coast Guard would introduce a new 
Sec. 111.105-40, Additional requirements for RO/RO vessels, to reflect 
current international classification society rules regarding RO/RO 
vessels. Additionally, means of alternative compliance is provided by 
citing IEC Zone classification.
    Section 111.105-41. The Coast Guard would revise Sec. 111.105-41, 
Battery rooms, to incorporate the provisions of internationally 
recognized IEEE Standard 45.
    Section 111.105-45. The Coast Guard would add Sec. 111.105-45, 
Vessels carrying agricultural products, to identify hazardous locations 
on vessels carrying certain agricultural products in bulk due to the 
hazards associated with grain dust. The proposed requirements are 
identical to the information published in Navigation and Vessel 
Inspection circular (NVIC) 9-84 ``Electrical Installations in 
Agricultural Dust Locations'' which has been Coast Guard policy since 
this subchapter was last revised.
    Section 111.105-47. The Coast Guard would add a new Sec. 111.105-
47, Duct keel ventilation or lighting, to reflect 

[[Page 4140]]
international practice by citing recognized classification society 
rules for ventilation, lighting and gas detection in special areas such 
as pipe tunnels, double bottoms and duct keels.
    Subpart 111.107. The Coast Guard would revise subpart 111.107, 
Industrial Systems, to define the subject term. The proposed definition 
would expand the applicability of industrial systems to vessel types 
other than Mobile Offshore Drilling Units. Additionally, the Coast 
Guard proposes the general safety requirements of Secs. 111.12-1(b) and 
111.12-1(c) for generator prime movers be applied to industrial system 
prime movers.

Part 112--Emergency Lighting and Power Systems

    Section 112.05-1. The Coast Guard would revise paragraph (a) in 
Sec. 112.05-1, Purpose, to remove ambiguity with regard to the purpose 
and intent of ensuring a dependable, independent and dedicated 
emergency power source. The Coast Guard would add a new paragraph (c) 
to allow the Commanding Officer, Marine Safety Center, to authorize 
certain electrical loads be connected to the emergency power source. 
These include loads that may be required in an emergency due to the 
particular mission or configuration of the vessel. When these 
additional loads are connected to the emergency power source, the 
emergency power source must be sized to handle these loads using a 
unity (1.0) service factor or an automatic load shedding scheme which 
removes these loads before overloading the emergency source of power.
    Section 112.05-5. The Coast Guard would revise paragraph (a) of 
Sec. 112.05-5, Emergency power source, to reference possible additional 
loads allowed by the Commanding Officer, Marine Safety Center in 
accordance with the proposed addition of Sec. 112.05-1(c) above. The 
Coast Guard would revise note 1 of Table 112.05-5(a) to be consistent 
with ABS rule 4/5.40.4. The Coast Guard would revise paragraph (c), 
which addresses the requirements for emergency power installations, to 
incorporate a reference to subchapter S (Stability). This would require 
a vessel's emergency power installation to function at specific angles 
of heel and trim, depending on the vessel type. The Coast Guard would 
revise paragraph (d), which addresses the requirements for the 
emergency power source, by adding associated transforming equipment and 
the emergency switchboard to the list of equipment required to be 
located aft of the collision bulkhead, outside the machinery space, and 
above the uppermost continuous deck. The Coast Guard interprets SOLAS 
74 as requiring the ``emergency source of power'' to include the power 
source, any associated transforming equipment, and the emergency 
switchboard. This proposed change also prohibits any other equipment 
from being located in the same space as the emergency power source and 
its associated equipment. The Coast Guard would revise paragraph (e) to 
conform with the requirements imposed by SOLAS 74 II-1/43-1.3.
    Section 112.15-1. The Coast Guard would revise paragraphs (c), (g), 
(j), and (k) of Sec. 112.15-1, Temporary emergency loads, to 
incorporate the semantics used in SOLAS 74. Paragraph (p) would be 
revised to include gas detection systems. New paragraph (q) would be 
added to include lighting for helicopter operations, if installed. New 
paragraph (r) would be added to include general emergency alarm power, 
reflecting SOLAS 74 requirements in Regulation III/50.
    Section 112.15-5. The Coast Guard would revise paragraph (b) in 
Sec. 112.15-5, Final emergency loads, to identify the circuits of a 
passenger elevator that must be powered from the final emergency power 
source regardless of the type of vessel. The Coast Guard would also 
revise paragraph (f) to require electrically-driven sprinkler systems, 
water-spray extinguishing systems, and the foam system pump to be 
powered from the final emergency source of power, paragraph (g) to 
include a geared diesel's lube oil pump which was unintentionally 
omitted at the last revision of this section, and paragraph (i) to 
specifically mention new Global Marine Distress Safety System 
installations (GMDSS). The Coast Guard would combine paragraphs (j), 
(k), (l), (m), and (n) into a single paragraph concerning navigation 
aids, all of which are either required or recommended by international 
practice. This change will allow a degree of latitude in eliminating 
unnecessary navigation equipment from that required to be powered from 
the final emergency power source. As a result of this change, 
paragraphs (o), steering gear feeders, (p), general alarm, (q), blow-
out preventer, (r), diving systems, (s), emergency generator starting 
air compressor, and (t), steering gear failure alarm, of this section 
would be re-lettered as paragraphs (k), (l), (m), (n), (o), and (p). 
The Coast Guard would add paragraphs (q), (r), (s), (t), (u), and (v) 
to require that the following be powered from the final emergency 
source: the ballast control systems on column-stabilized MODUs, the 
automation loads required by part 62 of this chapter, motor-operated 
valves for cargo and fuel oil systems if the emergency source of power 
is their source of power to meet Sec. 56.50-60(d), stabilizer wing 
positioning motors and indicators and smoke extraction fans and 
CO2 exhaust fans.
    Section 112.39-1 and 112.39-3. The Coast Guard would eliminate 
paragraph (a)(4) of Sec. 112.39-1, General, as Sec. 112.39-3, 
Operations, sufficiently defines the performance requirements of the 
lanterns. The Coast Guard would revise paragraph (a) of Sec. 112.39-3, 
Operation, to conform with SOLAS 74 Regulation II-1/42-1.
    Section 112.43-1. The Coast Guard would revise paragraph (b) of 
Sec. 112.43-1, Switches, to change a reference from a deleted section 
to an active section.
    Sections 112.43-3 and 112.43-7. The Coast Guard would delete 
Sec. 112.43-3, Controls; general, and rename Sec. 112.43-7, Navigating 
bridge distribution panel. The Coast Guard would revise certain entries 
in paragraph (a) to make terminology consistent with SOLAS 74. The 
present Sec. 112.43-3 repeats the requirements of Sec. 112.43-7.
    Section 112.43-5. The Coast Guard would revise Sec. 112.43-5, 
Controls on island type vessels, to replace the terms ``lifeboat'' and 
``liferaft'' with the term ``survival craft'' to agree with SOLAS 74.
    Section 112.43-11. The Coast Guard would revise Sec. 112.43-11, 
Illumination for launching operations, to replace the terms 
``lifeboat'' and ``liferaft'' with the term ``survival craft'' to agree 
with SOLAS 74.
    Section 112.43-15. The Coast Guard would revise Sec. 112.43-15, 
Emergency lighting feeders, to replace the term ``firescreen'' with the 
term ``fire'' to agree with SOLAS 74.
    Section 112.43-17. The Coast Guard would delete Sec. 112.43-17, 
Emergency light markers. The requirement that all emergency lights be 
individually marked is overly restrictive and does not provide a 
significant safety feature.
    Section 112.45-5. The Coast Guard would relocate the requirements 
of Sec. 112.45-5, Test switch, to subpart 111.30, Switchboards. This 
proposed change would consolidate the requirements for equipment 
required to be on the emergency switchboard in one section.
    Section 112.50-1. The Coast Guard would combine paragraphs (d) and 
(e) in Sec. 112.50-1, General, to clarify that diesel or gas turbine 
engines used to power emergency generators must not have any starting 
aids, except a thermostatically-controlled electric water-jacket heater 
connected to the final emergency bus. Additionally, the 

[[Page 4141]]
time for the emergency generator to be capable of carrying its full 
load is increased from 20 to 45 seconds to agree with SOLAS 74.
    Sections 112.50-1, 112.50-3, 112.50-5, and 112.50-7. The Coast 
Guard would add new paragraph (k) of Sec. 112.50-1 to include 
requirements for starting devices on emergency generating sets. SOLAS 
74, Regulation II-1/44, requires that ``Each emergency generating set 
arranged to automatically start shall be equipped with starting devices 
approved by the administration with a stored energy capability of at 
least three consecutive starts. A second source of energy shall be 
provided for an additional three starts within 30 minutes unless manual 
starting can be demonstrated to be effective.'' The proposed change 
parallels the International Association of Classification Societies 
(IACS) interpretation and affects Sec. 112.50-3, Hydraulic starting; 
Sec. 112.50-5, Electric starting; and Sec. 112.50-7, Compressed air 
starting which are therefore being revised.
    Section 112.55-15. The Coast Guard would revise Sec. 112.55-15, 
Capacity of storage batteries, to reflect the requirements of SOLAS 74 
regarding opening and closing of watertight doors. This is similar to 
the change proposed to subpart 111.97, Electric Power-Operated 
Watertight Door Systems, which addresses hydraulic opening and closing 
of watertight doors.

Part 113--Communication and Alarm Systems and Equipment

    Subpart 113.10. The Coast Guard would revise the title of subpart 
113.10, Fire Detecting and Alarm Systems and Manual Fire Alarm Systems, 
to include smoke detecting systems.
    Section 113.10-7. The Coast Guard would revise Sec. 113.10-7, 
Connection boxes, to introduce alternative methods of compliance by 
referencing standards of construction of the IEC.
    Section 113.10.9. The Coast Guard would revise paragraph (a) of 
Sec. 113.10-9, Power supply, to align fire detection system equipment 
requirements according to international practice, and remove paragraph 
(c).
    Section 113.20-3. The Coast Guard would change the title of 
Sec. 113.20-3, Watertight equipment, to a more general term, Connection 
boxes, to introduce alternative methods of compliance by referencing 
the construction standards of the IEC.
    Section 113.25-6. The Coast Guard would revise paragraphs (d) and 
(e) of Sec. 113.25-6, Power supply. In view of technological advances 
in electronic simulation and our acceptance of IEC voltages, the 6-120 
volt requirement is unnecessarily restrictive. Additionally, since 
SOLAS 74 Regulation III/50 requires the general emergency alarm to be 
powered from the main and emergency source, the Coast Guard proposes to 
refer to that regulation in this paragraph instead. Paragraph (e) would 
contain wording to retain battery, temporary emergency bus and 
communication switchboard options.
    Section 113.25-8. The Coast Guard would revise paragraphs (b), (c), 
(f) and (g) in Sec. 113.25-8, Distribution of general alarm system 
feeders and branch circuits, to remove the restriction of having only 
five general alarm bells on a branch circuit. The existing regulation 
used an arbitrary number to ensure that the branch circuit was not 
overloaded. The specific reference to fuses will be replaced by a 
general statement regarding overcurrent protection. The remaining 
requirements ensure that a circuit is not compromised by a fault in 
another part of the vessel. Additionally, the size of vertical zones, 
mentioned in paragraph (g), is changed to meet the accepted main 
vertical fire zone dimension.
    Section 113.25-9. The Coast Guard would revise paragraph (b) of 
Sec. 113.25-9, Location of general alarm bells, to remove the detailed 
acoustic specifications. These specifications are replaced with more 
general performance requirements in proposed new paragraph (c).
    Section 113.25-10. The Coast Guard would revise Sec. 113.25-10, 
Location of flashing red lights, to include existing policy that only 
general alarm beacons, used in high noise areas, be red. This is 
required so that personnel are not confused by the use of the same 
visual signal to indicate a number of conditions.
    Section 113.25-11. The Coast Guard would revise Sec. 113.25-11, 
Contact makers, to remove the detailed construction requirements for 
the general alarm contact maker. The performance requirements for this 
component remain in effect.
    Section 113.25-12. The Coast Guard would revise Sec. 113.25-12, 
Vibrating bells, to allow the use of electronic devices to simulate the 
sound produced by a vibrating bell.
    Section 113.25-16. The Coast Guard would revise Sec. 113.25-16, 
Fuses, to have this regulation apply to circuit breakers and fuses, 
both of which are allowable overcurrent devices.
    Subpart 113.30. The Coast Guard would revise subpart 113.30, Sound 
Powered Telephone and Voice Tube Systems. Voice tubes will be 
eliminated and, owing to today's technology, the Coast Guard will allow 
for choices by recognizing systems of communications other than sound 
powered phones that are accepted by recognized classification society 
rules.
    Section 113.30-1. The Coast Guard would revise Sec. 113.30-1, 
Applicability, to require self-propelled Mobile Offshore Drilling Units 
meet the same requirements as other self-propelled vessels.
    Section 113.30-5. The Coast Guard would revise paragraphs (a), (d), 
(g), (h), and (i) of Sec. 113.30-5, Requirements, to generalize 
communication systems and to incorporate the necessary clarifications 
pertinent to Mobile Offshore Drilling Unit applications. The Coast 
Guard would add new paragraph (j) to the list of locations where common 
means of voice communication and calling are required. This requirement 
increases the level of safety aboard the vessel and is consistent with 
the requirements of SOLAS 74.
    Section 113.30-20. The Coast Guard would revise paragraphs (a), 
(b), and (d) (paragraph (d) will be relettered as (c)) of Sec. 113.30-
20, Sound-powered telephone systems: General requirements, to correct 
the semantics of referencing ``communications systems'' versus only 
``sound-powered phones''.
    Section 113.30-25. The Coast Guard would revise paragraph (a) of 
Sec. 113.30-25, Sound-powered telephone system; detailed requirements, 
to remove the requirement that sound-powered telephones be approved by 
the Commandant. The remaining regulations are sufficient to ensure 
proper installation and operation of sound-powered telephones, or other 
reliable means of voice communications and calling.
    Section 113.35-3. The Coast Guard would revise paragraph (e)(3) of 
Sec. 113.35-3, General requirements, to reflect the above change in 
interior communications terminology.
    Sections 113.35-5 and 113.35-7. The Coast Guard would revise 
Sec. 113.35-5, Electric engine order telegraph systems; general 
requirements, and Sec. 113.35-7, Electric engine order telegraph 
systems; detailed requirements, to eliminate the detailed design 
specifications for electric engine-order telegraph systems. These two 
sections are combined under Sec. 113.35-5 to produce a single section 
addressing performance requirements.
    Sections 113.35-9 and 113.35-11. The Coast Guard would revise 
Sec. 113.35-9, Mechanical engine order telegraph systems; general 
requirements, and Sec. 113.35-11, Mechanical engine order telegraph 
systems; detailed requirements, to eliminate the detailed design 
specification for mechanical 

[[Page 4142]]
engine-order telegraph systems. These two sections are combined under 
Sec. 113.35-9 to produce a single section addressing performance 
requirements.
    Section 113.37-5. The Coast Guard would correct semantics 
concerning ``navigating bridge'' versus ``wheelhouse'' in Sec. 113.37-
5, General requirements.
    Section 113.37-10. The Coast Guard would remove paragraphs (b), 
(c), and (d) in Sec. 113.37-10, Detailed requirements. Most of these 
requirements represent standard marine practice, thereby making 
regulation unnecessary. New paragraph (b) would restate present 
paragraph (c)'s watertight requirement with international standard 
option.
    Section 113.40-10. The Coast Guard would revise Sec. 113.40-10, 
Detailed requirements, to add clarifying language that rudder-angle 
indicator circuits must be separate and independent from the autopilot 
and the dynamic positioning system as well as the steering gear control 
system. The Coast Guard would also remove paragraphs (b), (c), (d), 
(e), and (f) in this section. Most of these requirements represent 
standard marine practice, thereby making regulation unnecessary. New 
paragraph (b) would restate present paragraph (e)'s watertight 
requirement with international standard options.
    Sections 113.43-3 and 113.43-5. The Coast Guard would revise 
paragraph (a) of Sec. 113.43-3, Alarm system, and (b) of Sec. 113.43-5, 
Power supply, by substituting ``navigating bridge'' for ``pilothouse'' 
or ``wheelhouse''.
    Subpart 113.50. The Coast Guard would revise and rename subpart 
113.50, Emergency Loudspeaker Systems, to read, Public Address Systems, 
in order to incorporate performance requirements which are now in 
subchapter Q, subpart 161.004. The Coast Guard would eliminate 
subchapter Q, subpart 161.004. These proposals are consistent with 
SOLAS 74 III/6.4.
    Subpart 113.65. The Coast Guard would revise subpart 113.65, 
Whistle Operators, to correct the reference to IEEE Standard 45.
    Subpart 113.70. The Coast Guard would eliminate subpart 113.70, 
Smoke Detector Systems. This equipment is now included with Fire 
Detecting Systems in the proposed revision to Sec. 113.10.

Part 161--Electrical Equipment

    Subpart 161.002. The Coast Guard would extensively revise subpart 
161.002, Fire-Protective Systems, in order to eliminate overly 
restrictive construction requirements and to provide for options in the 
manufacture and testing of fire and smoke detecting and alarm systems 
via internationally accepted standards.
    Subpart 161.004. The Coast Guard would delete subpart 161.004, 
Emergency Loudspeaker System. The performance requirements would be 
incorporated into subpart 113.50, which would be renamed Public Address 
Systems. SOLAS 74 Regulation III/6-4.2 requires every vessel that has a 
general alarm to have a public address system (or other suitable means 
of communications) to supplement the general alarm.

Incorporation by Reference

    Material that would be incorporated by reference throughout 
subchapter J is listed in Sec. 110.10-1. Copies of the material are 
available for inspection where indicated under ADDRESSES. Copies of the 
material are available from the sources listed in Sec. 110.10-1.
    Before publishing a final rule, the Coast Guard will submit this 
material to the Director of the Federal Register for approval of the 
incorporation by reference.

Regulatory Evaluation

    This proposal 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).
    The Coast Guard expects the economic impact of this proposal to be 
so minimal that a full Regulatory Evaluation under paragraph 10e of the 
regulatory policies and procedures of DOT is unnecessary.
    The Coast Guard has found that most of the changes to the 
Electrical Engineering Regulations are either editorial or they update 
technical specifications to reflect the latest practices. There are 
some regulatory changes that will require different construction. 
Although some of these changes will cause minor cost increases for 
shipbuilders, others will result in substantial savings. Many of the 
proposed rulemaking changes causing cost increases are already current 
marine industry practice. The remaining changes causing cost increases 
are more than offset by the cost savings offered by several relaxations 
in the regulations.
    Overall, it is anticipated that there will be a net cost reduction 
offered for vessels constructed under these rules, but the exact impact 
is difficult to determine accurately since it may vary from vessel to 
vessel. For certain vessels, new requirements may increase costs, but 
the application of national and international industry consensus 
standards should enhance performance and thus increase the level of 
safety. Additionally, due to cost decreases that may result from the 
removal of the requirements for armor on cable, allowance of the use of 
NEC and IEC motors, and a variety of circuit breakers conforming to 
international standards in panelboards, it may be possible to 
significantly lower costs for each vessel. Actual savings will depend 
upon the industry practices followed by each vessel designer/shipyard 
before and after the effective date of these regulations.
    In addition to the savings in material costs, there are several 
intangible benefits. Due to the increased reference to national and 
international standards other than the National Electrical Code and 
Underwriters Laboratories Inc., certain equipment items will now be 
more readily available ``off the shelf'' for marine use. The proposed 
regulations will 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.
    The Coast Guard expects that significant economic savings will 
result from the ability of equipment manufacturers, in many cases, to 
meet performance specifications instead of design standards and the 
elimination of the need to submit to the U.S. Coast Guard detailed 
plans and specifications for approval for equipment such as sound 
powered telephones, emergency loudspeaker systems, and navigation 
lights.
    The Coast Guard solicits cost data and comments regarding the 
economic impact of these proposed requirements from all interested 
parties.

Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the 
Coast Guard must consider whether this proposal, if adopted, will have 
a significant economic impact on a substantial number of small 
entities. ``Small Entities'' may include (1) small businesses and not-
for-profit organizations that are independently owned and operated and 
are not dominant in their fields and (2) governmental jurisdictions 
with populations of less than 50,000.
    The Coast Guard believes it has addressed the concerns of many 
small 

[[Page 4143]]
entities by the adoption of wide variety of national and international 
standards regarding system arrangement. Additionally, the proposed 
regulations will dramatically revise certain prescriptive electrical 
equipment design, specification, and approval requirements, and replace 
them with performance-based requirements that incorporate international 
standards.
    Whenever possible, requirements have been adjusted to the size of 
the vessel and in some cases a relaxation of requirements for smaller 
vessels has been offered. Due to the flexibility of requirements in 
these proposed rules and the eliminating of regulatory burden, small 
entities involved in the building or ownership of vessels should 
experience increasing business opportunities.

Collection of Information

    Under the Paperwork Reduction Act (44 U.S.C. 3501 et. seq.), the 
Office of Management and Budget (OMB) reviews each proposed rule which 
contains a collection-of-information requirement to determine whether 
the practical value of this information is worth the burden imposed by 
its collection. Collection-of-information requirements include 
reporting, recordkeeping, notification, and other, similar 
requirements.
    This proposed rule contains collection-of-information requirements 
in the following subparts: subpart 110.25 in subchapter J and subparts 
161.002 and 161.010 in subchapter Q. The following particulars apply to 
subpart 110.25:
    DOT No.: 2115.
    OMB Control No.: 2115-0115.
    Administration: U.S. Coast Guard.
    Title: Electrical Engineering Regulations--Subchapter J.
    Need for Information: This proposed rule would require amendments 
to the regulations, clarify the regulations, bring them up to date, and 
delete unnecessary requirements. The revisions to subchapter J will 
reduce the reliance on domestic standards and will adopt SOLAS 74 and 
other international standards developed through consensus by the 
international maritime community.
    Proposed Sec. 110.25-1 would require industry to complete 
electrical engineering plans to meet performance requirements on new-
built vessels and modifications of current vessels. These requirements 
will help resolve much of the confusion during inspections which has 
risen due to the complexity of electrical system arrangements on modern 
merchant vessels.
    Proposed Use of Information: The reporting of this information is 
necessary to ensure compliance with electrical engineering safety 
regulations. Through the review of the design plans prior to 
construction, the vessel owner or builder may be assured that the 
vessel, if built in accordance with the plans, will meet regulatory 
standards.
    Frequency of Response: The various information called for in 
Sec. 110.25 would be reported on occasion. Design plans will only be 
submitted when there is construction of new-built vessels or 
modification of current vessels.
    Burden Estimate: 478 hours.
    Respondents: 175 owners or operators.
    Average Burden Hours per Respondent: 1 hour per submission.
    The following particulars apply to subparts 161.002 and 161.010:
    DOT No.: 2115.
    OMB Control No.: 2115-0121.
    Administration: U.S. Coast Guard.
    Title: Equipment, Construction, and Materials: Specifications and 
Approval--Subchapter Q.
    Need for Information: This proposed rule world require amendments 
to the regulations, clarify the regulations, bring them up to date, and 
delete unnecessary requirements. The revisions to subchapter Q will 
required industry to maintain records of production tests for some fire 
protection systems. These plans consist mainly of system/material tests 
that are necessary to determine that the equipment being used in the 
construction of a fire protection system meets the minimum performance 
requirements.
    The following is a section-by-section justification of the 
collection requirements.
    Proposed subpart 161.002 would require manufacturers to complete 
electrical specifications to meet performance requirements for fire 
protection systems. This requirement will help identify specific 
equipment approved and to permit the production of equipment identical 
to the equipment samples originally tested.
    Proposed Use of Information: The reporting of this information is 
necessary to ensure compliance with electrical system arrangement/
equipment and fire protection system regulations. Through the review of 
approval plans, the manufacturer may be assured that the material or 
device, if manufactured in accordance with the material specifications, 
will meet regulatory standards.
    Frequency of Response: The various information called for in 
subpart 161.002 would be reported on occasion. Approval for equipment 
will only be submitted when production tests are required.
    Burden Estimate: 60 hours.
    Respondents: 6 manufacturers.
    Average Burden Hours Per Respondent: 10 hours per respondent.
    The Coast Guard has submitted the requirements to OMB for review 
under section 3504(h) of the Paperwork Reduction Act. Persons 
submitting comments on the requirements should submit their comments 
both to OMB and to the Coast Guard where indicated under ADDRESSES.

Federalism

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

Environment

    The Coast Guard has considered the environmental impact of this 
rule and concluded that, under paragraphs 2.B.2e(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 in 
the enhancement of vessel safety, and thereby help to minimize any 
impact to the marine environment. A ``Categorical Exclusion 
Determination'' is available in the docket for inspection or copying 
where indicated under ADDRESSES.
