Electrical Engineering Requirements for Merchant Vessels

AGENCY: Coast Guard, DOT.

ACTION: Interim rule with request for comments.

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

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out-of-date regulations, and eliminate requirements that create an 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 rule is effective on September 30, 1996. Comments must be 
received on or before August 5, 1996. The incorporation by reference of 
certain publications listed in the regulation are effective as of 
September 30, 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

SUPPLEMENTARY INFORMATION: 

Request for Comments

    The Coast Guard encourages interested persons to participate in 
this rulemaking by submitting written data, views, or arguments, 
particularly on the changes made since the notice of proposed 
rulemaking of February 2, 1996, was published. It is not necessary to 
resubmit comments submitted under that notice.
    Persons submitting comments should include their names and 
addresses, identify this rulemaking (CGD 94-108) and the specific 
section of this rule to which each comment applies, and give the reason 
for each comment. Please submit two copies of all comments and 
attachments in an unbound format, no larger than 8\1/2\ by 11 inches, 
suitable for copying and electronic filing. Persons wanting 
acknowledgement of receipt of comments should enclose stamped, self-
addressed postcards or envelopes.
    The Coast Guard will consider all comments received during the 
comment period. It may change this rule in view of the comments.
    The Coast Guard plans no additional public meetings. Persons may 
request a public meeting by writing to the Marine Safety Council at the 
address under ADDRESSES. The request should include the reasons why a 
public meeting would be beneficial. If it determines that the 
opportunity for oral presentations will aid this rulemaking, the Coast 
Guard will hold a public meeting at a time and place announced by a 
later notice in the Federal Register.

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). Correction 
notices were published 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.

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 and 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 regulations with 
amendments to the International Convention for the Safety of Life at 
Sea, 1974, (SOLAS 74) since the electrical 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, both by letter 
and at the public meeting, and the changes made to the regulatory text 
since the NPRM 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) A number of comments suggested changes that require further 
consideration by the Coast Guard. For example, several comments 
recommended that certain other standards be referenced in the 
regulations as replacements for, or options to, those cited in the 
NPRM. A few comments suggested changes to sections not addressed in the 
NPRM. The recommended standards for incorporation by reference will be 
considered for inclusion in the final rule

[[Page 28261]]

of this rulemaking. These comments are noted in this section of the 
preamble as subject to further consideration.
    (2) A number of comments applauded 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.
    (3) One comment requested an additional 60 days for the comment 
period and at least four public meetings.
    In response, the Coast Guard extended the comment period an 
additional 15 days and held a public meeting on March 25, 1996. Under 
this interim rule, the comment period is reopened for an additional 45 
days.
    (4) One comment expressed concern that proposed mobile offshore 
drilling unit (MODU) regulations were being presented in a piecemeal 
fashion throughout subchapter J. It suggested that these amendments be 
added to the Coast Guard's MODU regulations and that subchapter I-A be 
revised to incorporate the 1989 International Maritime Organization 
(IMO) MODU Code.
    The Coast Guard has a long-range plan to extensively revise its 
MODU regulations in 46 CFR chapter I, subchapter I-A. At that time, 
both the IMO MODU Code and the American Bureau of Shipping Rules for 
Building and Classing Mobile Offshore Drilling Units (ABS MODU Rules) 
will be considered.
    (5) One comment expressed concern that the Coast Guard proposed to 
apply the International Convention for Safety of Life at Sea, 1974 
(SOLAS 74) in a blanket fashion to all vessels including MODU's.
    SOLAS 74 has not been applied to non-self-propelled MODU's under 
this rulemaking.
    (6) The terms ``wheelhouse'' and ``pilothouse'' have been replaced 
throughout subchapter J with the term ``navigating bridge'' as used in 
SOLAS 74.
    (7) One comment recommended that the incorporation by reference 
list include other equivalent international standards.
    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.
    (8) One comment recommended that all regulations in excess of 
international standards be removed and that the regulations incorporate 
rules promulgated by ABS or other recognized classification societies.
    The Coast Guard is continuing to address the issue in the ABS-
generated U.S. supplement. Presently, ABS Rules are undergoing a major 
revision and some provisions, even now, differ with those of other 
International Association of Classification Societies (IACS) members. 
The Coast Guard will consider revising those areas of its regulations 
in the future.

II. Comments to Specific Sections

    Sec. 108.170. (1) One comment indicated that this section is 
duplicated in Sec. 111.105-33.
    This rulemaking merely corrects a citation in the note to the 
section. This section, as well as the remainder of subchapter I-A, is 
under consideration for revision at a later date.
    (2) One comment suggested a change in the wording of Note 1 to 
align its terminology with subpart 111.105.
    This change has been made accordingly.
    Sec. 101.01-1. (1) Several comments suggested that paragraphs (a) 
and (b) were confusing and should be revised or combined.
    The paragraphs have been revised accordingly.
    (2) One comment requested that the effective date be changed from 
90 to 120 days to provide the additional time necessary to comply with 
the new regulations.
    The effective date has been set for September 30, 1996.
    (3) One comment suggested that the term ``vessels'', as used in 
proposed paragraph (b), be clarified to exclude fixed platforms.
    This change was not considered necessary because nowhere in Coast 
Guard regulations is the term ``fixed platform'' included in the 
definition of ``vessel.''
    (4) One comment suggested adding ``and its tributaries'' to the 
definition of Great Lakes vessel.
    The definition has been revised to align it with the definition of 
``Great Lakes'' in the Coast Guard's Inland Navigation Rules, 
Commandant Instruction M16672.2B (33 CFR chapter I, subchapter E).
    Sec. 110.01-3. One comment stated that this section is confusing.
    This section has been revised to discuss repairs and replacements, 
alterations and modifications, and conversions in separate paragraphs.
    Sec. 110.10-1. (1) Several comments noted that the Institute of 
Electrical and Electronic Engineer (IEEE) is in the process of revising 
its standards.
    The Coast Guard will consider these revisions when approved by IEEE 
and update this section accordingly.
    (2) One comment noted that Underwriters Laboratories Inc. (UL) 595 
is not cited in Sec. 111.60-11(c).
    The reference to that section has been deleted.
    (3) One comment noted that UL 50 is listed as being cited in 
Sec. 111.81-13(a) but this section is removed.
    UL 50 is now cited in Sec. 111.81-1.
    (4) One comment recommended that American Petroleum Institute (API) 
Recommended Practices (RP's) be incorporated by reference.
    API RP's are being considered for future rulemakings.
    (5) Two comments stated that some of the standards incorporated by 
reference in Secs. 110.10-1 and 161.002-1 may also be available in 
American National Standards Institute (ANSI) versions.
    Items approved by the Director of the Federal Register for 
incorporation by reference are required to be identified by the 
information on the cover of the document.
    (6) Several comments noted that MIL-C-24643 and MIL-C-24640 should 
read MIL-C-24643A and MIL-C-24640A.
    These have been changed accordingly.
    (7) Several comments noted that ANSI/UL 1581 (VW-1) should read 
ANSI/UL 1581.
    This title and the three sections referenced have been amended 
accordingly.
    (8) Several comments indicated that the Canadian Standards 
Association (CSA) standard CSA-C 22.2 No. 245/UL 1309, Marine Shipboard 
Cable, should be included.
    This standard is new and still under consideration by the Coast 
Guard.
    (9) Several comments requested that UL 1569, Metal-Clad Cables, 
should be included.
    The standard has been added as requested. See the discussion of 
Sec. 111.60-23 in this preamble.
    (10) One comment noted that American Society for Testing and 
Materials (ASTM) D 789, Standard Specification for Nylon Injection and 
Extrusion Materials (PA), should be ANSI/ASTM D 1897.
    The correct replacement for ASTM D 789 is ASTM D 4066-94B. The 
reference has been changed accordingly.
    (11) Many comments suggested that the references not cite the date 
of the document as they are periodically revised.
    As indicated in Sec. 110.10-1(a), only the edition listed in 
Sec. 110.10-1(b) can be enforced. The Coast Guard will consider

[[Page 28262]]

future revisions but must provide public notice for comment before 
adopting them.
    (12) One comment questioned whether the vessel must comply with the 
specific edition of a standard incorporated or could it comply with a 
later edition.
    When requested, provisions in later editions may be used if they 
are accepted by the Commanding Officer, Marine Safety Center (MSC), 
under subpart 110.20 or Sec. 161.002-17, as providing an equivalent 
level of safety.
    (13) Several comments suggested incorporating ABS MODU Rules into 
the following sections: Secs. 111.12-1(a), 111.12-3, 111.12-5, 111.12-
7, 111.33-11, 111.35-1, and 111.70-1(a).
    The ABS MODU Rules have been included as suggested.
    (14) One comment noted that International Electrotechnical 
Commission (IEC) Publication 533 was not mentioned in the referred 
section.
    The publication is now referenced in new Sec. 113.05-7 addressing 
environmental testing.
    (15) One comment questioned whether some of the material 
incorporated is the latest available edition or is readily available in 
the ANSI on-line catalog.
    The editions incorporated are the latest supplied to the Coast 
Guard by the organization which originated the standard.
    Sec. 110.15-1. (1) One comment recommended that the ABS definition 
of ``nonsparking fan'' is more complete and should be used.
    The definition has been changed accordingly.
    (2) Several comments pointed out inconsistencies in the definitions 
of ``waterproof'' and ``watertight'' and the associated National 
Electrical Manufacturers Association (NEMA) and IEC ingress protection 
(IP) ratings.
    The definitions and the text have been corrected accordingly.
    (3) One comment suggested that the definition of ``qualified 
person'' indicate that the person be qualified in electrical 
procedures.
    This change has been made accordingly.
    (4) One comment stated that the reference to Sec. 1.01 in the 
definition of ``Commandant'' is unnecessary and adds no value.
    The reference has been deleted.
    (5) One comment suggested deleting the definition of ``emergency 
squad'' since it no longer appeared in revised Sec. 113.30-5(d).
    ``Emergency squad'' has been reinserted in Sec. 113.30-5(d) for 
clarity.
    (6) The definition of the term ``independent laboratory'' has been 
added to this section. Minor conforming amendments have been made 
throughout subchapter J to accommodate this definition and subpart 
110.35 has been removed.
    Sec. 110.20-1. This section has been aligned with equivalency 
provisions in other recent Coast Guard rulemakings.
    Sec. 110.25-1. (1) Several comments stated that the requirement in 
proposed new paragraph (c)(12) for the owner to submit lists of 
equipment and components used in hazardous locations does little to 
improve safety because components are inspected during installation by 
the Officer in Charge, Marine Inspection (OCMI). Additionally, the 
comments point out most of the requirements are duplicated in paragraph 
(i).
    This requirement is retained because it is vital to the plan review 
process, which identifies suitability of each component and the system 
before installation. All of the required elements of the plan submittal 
have been included in revised paragraph (i) and proposed paragraph 
(c)(12) has been removed.
    (2) One comment recommended that the Coast Guard address, in the 
note to paragraph (n), the manufacturer's self-certification to a list 
standard when that standard requires third-party certification.
    A sentence has been added as recommended.
    (3) One comment pointed out that independent laboratories 
referenced must be accepted for testing and listing or certification.
    Paragraph (j) has been changed accordingly.
    Sec. 110.25-3. One comment observed that, in the note to paragraph 
(c), the Coast Guard Technical Office no longer exists.
    The Technical Office has been replaced by the Marine Safety Center. 
The note has been revised accordingly.
    Sec. 110.30-1. One comment stated that the CFR parts listed in this 
section were out of date.
    The section has been amended to avoid specifying individual parts.
    Sec. 110.30-5. One comment recommended that this section be removed 
because information regarding the scope of inspection is in the 
pertinent parts under which vessels are certificated.
    This section is necessary because the pertinent parts refer to 
subchapter J and because this section addresses inspection of 
electrical equipment specifically.
    Sec. 110.30-7. One comment suggested that notice to the OCMI is 
already required in the subchapter under which a vessel is certificated 
and that this section should be removed.
    Not all of these subchapters provide for this notice. Therefore, 
this section is retained.
    Subpart 110.35. (1) This subpart has been removed because 
``independent laboratory'' is now defined in Sec. 110.15-1, 
Definitions.
    (2) One comment requested that the Coast Guard use Occupational 
Safety and Health Administration's (OSHA's) Nationally Recognized Test 
Laboratory program.
    The Coast Guard's program under part 159, subpart 159.010, focuses 
on performance in the marine environment, rather than in the general 
workplace, as does the OSHA program. Any OSHA laboratory capable of 
testing to marine product performance and environment may apply for 
inclusion in the Coast Guard's program.
    Sec. 111.01-1. One comment suggested the addition of a general 
requirement that system integrity be maintained.
    A new paragraph (c) has been added accordingly.
    Sec. 111.01-5. Several comments recommended that the qualifier in 
paragraph (d) for electric cable be removed.
    This section has been revised to indicate that protection from 
bilge water is required for all of the equipment listed in paragraphs 
(a) through (d), if located in or around the bilge area.
    Sec. 111.01-7. One comment recommended adding the words ``and 
spacing'' to the title of this section because spacing is addressed in 
paragraph (b).
    The change was made accordingly.
    Sec. 111.01-9. (1) One comment requested that the words ``on deck'' 
be removed from paragraph (b) because the hazard could exist in other 
locations on the vessel.
    In line with this recommendation, paragraphs (a) and (b) were 
revised to align the minimum degree of protection required with the 
hazard rather than the specific location.
    (2) One comment requested that a NEMA Type 1 enclosure be the 
minimum requirement in paragraphs (a), (c), and (d).
    Paragraph (d) has been revised to reflect the suggestion. However, 
the minimum requirements for the equipment in paragraphs (a) and (c) 
have been adjusted to provide a slightly higher degree of protection 
consistent with the hazards and vital functions performed. The 
definitions for those locations requiring, and those locations not 
requiring, exceptional degrees of protection have been slightly revised 
accordingly.

[[Page 28263]]

    (3) One comment suggested modifying the second sentence of 
paragraph (a) to include the phrase ``pressure-directed liquids''.
    This change was made in paragraph (b) because of the amendments to 
paragraphs (a) and (b) discussed above.
    (4) One comment stated that personal computers and similar 
equipment should be allowed to be used as control consoles when not 
subject to exposure from liquids.
    Personal computers are not prohibited under this section if they 
meet the stated degrees of protection.
    Sec. 111.01-15. (1) One comment recommended a major revision of 
this section, including removing paragraphs (b) and (d), because the 
preamble to the NPRM failed to identify the international requirement 
upon which the proposal was based or to give any other justification.
    The design parameters for this section were based upon table 4 of 
IEC Publication 92-101, Electrical Installations in Ships--Part 101: 
Definitions and General Requirements. The paragraphs are retained.
    (2) One comment suggested minor editorial changes in paragraph (e).
    The recommendations to clarify paragraph (e) have been adopted.
    Sec. 111.01-17. One comment stated that the deletion of standard 
voltages may introduce the risk of proliferation of non-marine 
arrangements.
    This section replaces prescriptive regulation with performance 
criteria. The Coast Guard will consider refering to industry standard 
voltages and frequencies when IEEE Std 45 is revised.
    Secs. 111.01-19, 111.01-21, and 111.01-23. (1) Several comments 
stated that some requirements in these sections were in excess of ABS 
Rules for Building and Classing Steel Vessels (ABS Rules), and 
suggested the Coast Guard adopt ABS Rules for environmental testing.
    Section 111.01-19 is retained because it applies to all electrical 
equipment. Sections 111.01-21 and 111.01-23, although consistent with 
IEC Publication 92-101, have been removed because they apply to control 
equipment similar to that covered by the ABS Rules. Environmental 
testing requirements for communication, alarm, control, and monitoring 
equipment have now been addressed in new Sec. 113.05-7 incorporating 
table 4/11.1 of ABS Rules.
    (2) One comment suggested that Lloyd's Register Type Approval 
System--Test Specification Number 1 be incorporated for all electrical 
control equipment.
    The options of this test specification and ABS Rules table 4/11.1 
now appear in Sec. 113.05-7.
    (3) One comment suggested that inclination criteria be limited to 
conventional hulled or self-propelled vessels and not column stabilized 
units, such as MODU's and tension leg platforms (TLP's).
    The requirement is retained pending further consideration by the 
Coast Guard.
    (4) One comment noted that in Sec. 111.01-21 ``all electrical 
control equipment'' is too broad. Vibration criteria should be limited 
to vital propulsion and vessel control systems on self-propelled 
vessels.
    In addition to the discussion of the first comment to these 
sections, the requirements apply to the control and monitoring 
equipment referenced in ABS Rules 4/11 and communication and alarm 
systems under part 113 of this chapter.
    Sec. 111.05-07. Several comments suggested that IEC 92-352 be 
removed because it is obscure, misleading, and unnecessary and that it 
be replaced with a domestic standard.
    IEC Publication 92-352 has been replaced with IEC 92-3 and IEEE Std 
45 is added as an option.
    Sec. 111.05-9. One comment suggested incorporating the American 
Boat and Yacht Council Standard E-2 for lightning ground conductors.
    The Coast Guard is reviewing this standard for possible 
incorporation by reference.
    Sec. 111.05-23. Two comments indicated that the requirement in 
paragraph (d) was overly prescriptive and costly, with limited benefit. 
One suggested alternative locations.
    Paragraph (d) has been amended accordingly.
    Sec. 111.05-27. One comment suggested deleting the provision to 
``momentarily remove the indicating device from the reference ground'' 
because monitoring technology exists which obviates the need.
    The requirement is retained because not all ground detection 
systems employ such state-of-the-art design.
    Sec. 111.05-33. (1) Many comments suggested that the Coast Guard 
retain its current regulations for equipment grounding conductor size 
according to the National Electrical Code (the NEC).
    Paragraph (a) has been revised as suggested.
    (2) Many comments discussed the proposal to require that equipment 
grounding conductors be insulated.
    Paragraph (b) has been revised to reference the NEC article 310-
12(b) for conductor covering and identification.
    (3) Many comments agreed with the proposal of prohibiting cable 
armor from being used as the grounding conductor and suggested adding 
metallic sheath to the regulation.
    Paragraph (c) has been revised as suggested and moved to a more 
appropriate location in Sec. 111.60-5(d).
    (4) One comment suggested adding a reference to IEC requirements 
for grounding conductors, noting that the 1996 revision of ABS Rules 
will be incorporating the IEC criteria.
    The IEC criteria is presently under review pending ABS 
incorporation.
    Sec. 111.10-7. One comment stated that paragraph (b) duplicates the 
provisions of Sec. 112.05-5.
    This paragraph is intended to introduce general dead ship power 
requirements into subpart 111.10, Power Supply. Section 112.05-5 
contains more detailed requirements.
    Sec. 111.10-9. One comment stated that the sizing and transformer 
redundancy requirements are overly prescriptive for other than self-
propelled vessels.
    The requirements are for ship's service supply loads listed in 
Sec. 111.10-4(b). Propulsion accounts for only a portion of the loads. 
The transformer requirements are retained for non-self-propelled 
vessels because of safety and habitability considerations.
    111.12-1. (1) One comment pointed out that the overspeed trip 
requirement in paragraph (b) may not be entirely practicable because 
some manufacturers recommend different settings, such as 18 percent.
    The requirement is consistent with ABS Rules and is retained. If a 
manufacturer designs and recommends a trip value in excess of this 
requirement, the manufacturer may apply for equivalency under part 110, 
subpart 110.20.
    (2) One comment pointed out that pressure-lubricated generator 
bearings mentioned in paragraph (c) are rare. The comment also 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 revision to paragraph (c) in the NPRM was to expand the present 
provision to consider proliferation of shaft driven generators. The 
Coast Guard is reviewing its requirements for generator prime movers 
and will address shutdown upon loss of lube oil in another rulemaking.
    Sec. 111.12-11. (1) Several comments recommended replacing the 
words ``inverse time,'' in paragraph (c)(1), with the word ``longtime'' 
to be consistent

[[Page 28264]]

with the proposed change to paragraph (d).
    Paragraph (c)(1) has been amended as suggested.
    (2) One comment suggested a complete revision of paragraph (g) to 
align terminology with SOLAS 74 and allow deviations on a case-by-case 
basis.
    The requirements are considered comparable. Case-by-case 
equivalences are already provided for under part 110, subpart 110.20.
    Sec. 111.15-2. One comment discussed the change in the angle of 
inclination of a battery cell from the existing 30 degrees to the 
proposed 40 degrees, stating that one specific angle is not appropriate 
for all vessel types in determining suitability for marine use.
    The figure of 40 degrees static inclination is from the 
international standards of IEC Publications 92-101 and 92-305 and is 
applicable to all vessels. However, the Coast Guard recognizes that a 
40 degree static inclination may be beyond the reasonable or practical 
limits for certain vessels to which these regulation apply. Where 
installations are made on specific vessels that cannot attain or 
sustain a 40 degree static inclination, a lesser value may be accepted 
under the equivalency provisions in subpart 110.20.
    Sec. 111.15-5. (1) One comment suggested the prescriptive language 
in paragraph (d), be replaced with performance standards relative to 
battery tray clearance.
    Paragraph (d) has been amended as suggested.
    (2) One comment discussed the need to differentiate between 
cranking and other types of batteries in paragraph (e).
    Paragraph (e) has been revised as suggested.
    Sec. 111.15-20. One comment suggested a minor wording order change 
in paragraph (c) for clarity.
    Paragraph (c) has been revised as suggested.
    Sec. 111.15-30. One comment suggested that portable battery 
chargers incorporating an autotransformer may impose an intentional 
ground on a vessel's power supply system and, therefore, should not be 
used.
    A sentence was added prohibiting the use of chargers incorporating 
grounded autotransformers.
    111.30-1. One comment recommended incorporating IEC standards on 
switchboards.
    The incorporation has been made accordingly.
    Sec. 111.30-5. (1) One comment observed that the wire sizes 
mentioned in the reference of paragraph (a) differed from those cited 
in Sec. 111.30-19(b)(3).
    Section 111.30-19(b)(3) has been revised accordingly.
    (2) One comment pointed out that the requirement in paragraph (b) 
repeats the requirement in Sec. 111.01-9.
    Paragraph (b) is retained because it additionally mentions deck-to-
overhead construction.
    (3) One comment noted that low and medium voltage is defined 
differently in the IEEE and IEC standards.
    Paragraphs (a)(1) and (a)(2) have been revised to reflect this 
difference.
    Sec. 111.30-19. (1) One comment stated that section 17.11 of IEEE 
Std 45, as referred to in paragraph (a)(1), itself refers to the NEC 
article 384-26 (1981). The comment suggested that, where an edition of 
a standard is referred to in a document incorporated by reference, the 
latest edition of that standard applies.
    Until IEEE Std 45 adopts a newer edition of the 1981 NEC and the 
Coast Guard incorporates the new IEEE Std 45, the 1981 edition of the 
NEC applies in this instance.
    (2) One comment pointed out that there are no specific acceptance 
criteria in subchapter J for aluminum bus bars.
    Guidelines for aluminum bus bar installations are contained in 
Coast Guard Navigation and Vessel Inspection Circular (NVIC) 2-79 and 
are considered to provide adequate guidance on aluminum bus bars until 
the new revision of IEEE Std 45 is published and incorporated by 
reference.
    Sec. 111.30-24. One comment requested that the exclusion for a non-
self-propelled MODU be expanded to include flotating Outer Continental 
Shelf (OCS) facilities.
    This section has been revised to extend the exclusion to a non-
self-propelled floating Outer Continental Shelf (OCS) facility.
    Sec. 111.30-29. (1) One comment pointed out that proposed paragraph 
(i) was merely a repetition of the requirement in Sec. 112.05-5(h).
    Paragraph (i) has been removed accordingly.
    (2) One comment suggested that the section would appear better 
organized if proposed paragraphs (g) and (h) were inserted after 
existing paragraph (a).
    The section has been revised accordingly.
    Sec. 111.30-31. One comment recommended that Sec. 111.30-31 be 
retained because, even though the current ABS Rules do not include 
switchboard testing, the new 1996 ABS Rules will.
    The Coast Guard will consider reinstating the requirement when ABS 
issues its new rules.
    Sec. 111.40-5. One comment recommended that this section be removed 
because it is redundant and is only a cross-reference to the 
requirements of Secs. 111.01-9.
    This section has been retained to address the noncombustible 
requirement and to cross-reference the accessibility and degree-of-
protection requirements in Secs. 111.01-7 and 111.01-9.
    Sec. 111.40-7. One comment suggested rewriting this section for 
ease of comprehension.
    This section has been rewritten as suggested, without substantive 
change.
    Sec. 111.50-3. (1) Several comments noted that the word ``not'' was 
inadvertently omitted from paragraph (c).
    The paragraph has been revised accordingly.
    (2) One comment suggested adding the clarifying phrase ``standard 
fuse or circuit breaker'' after the words ``next larger'' in paragraph 
(c).
    This paragraph has been revised accordingly.
    (3) One comment suggested revising the last sentence of paragraph 
(c) to clarify the intent of the requirement.
    Paragraph (c) has been revised accordingly.
    Sec. 111.52-3. One comment pointed out that, although this section 
was not addressed in the NPRM, it merely repeats criteria given in IEEE 
Std 45.
    The Coast Guard will consider revising this section when the new 
IEEE Std 45 is published.
    Sec. 111.52-5. One comment suggested deleting the word ``Detailed'' 
from the introductory text because the following paragraphs (a) through 
(d) defined the level of detail.
    The word ``Detailed'' has been removed as suggested.
    Sec. 111.53-1. One comment suggested replacing ``Sec. 110.35-1'' in 
paragraph (a)(3) with ``part 159'' because Sec. 110.35-1 merely cites 
part 159 of this chapter.
    ``Independent laboratory'', as now defined in Sec. 110.15-1, 
references part 159 and subpart 110.35 has been removed.
    Sec. 111.54-1. One comment suggested the addition of ``one of the 
following:'' to the end of the introductory text of paragraph (c)(1) so 
that only one of the stated standards need be complied with.
    Paragraph (c)(1) already provides for this.
    Subpart 111.60. (1) Several comments pointed out that MIL-C-915 is 
an obsolete standard and should be removed.
    The standard has been removed.
    (2) Several comments indicated that MIL-C-24640 and 24643 are now 
in modification A status.
    The modification A edition of both standards has been referenced.
    (3) Many comments pointed out that ``VW-1'' is a test that resides 
in ANSI/UL 1581.

[[Page 28265]]

    The standard is now cited as ``ANSI/UL 1581 test VW-1.''
    (4) Several comments suggested that Coast Guard regulations be 
harmonized with the NEC along with ANSI and otherwise recognized 
national standards.
    One of the primary elements of this and other current Coast Guard 
rulemakings is the incorporation of both international and domestic 
recognized industry standards where appropriate. Article 90-2(b)(1) of 
the NEC states that the NEC does not cover installations in ships. In 
many cases, however, certain specific recommendations of the NEC are 
considered appropriate for inclusion into the regulations.
    Sec. 111.60-1. (1) Several comments questioned whether the Coast 
Guard will accept cables equivalent to those stated in this section.
    Equivalents may be accepted under Sec. 110.20-1.
    (2) Many comments requested that the 75 deg.C requirement in 
paragraph (c)(6) be changed to 90 deg.C, as allowed in USA/Canadian 
binational shipboard cable standard UL 1309/CSA C22.2 No. 245.
    The requirement for 75 deg. is retained in accordance with IEEE Std 
45 and classification society rules. UL 1309/CSA C22.2 No. 245 is not 
recognized by either the Coast Guard or the Ship Inspection 
Directorate, Transport Canada.
    (3) Several comments noted that International Association of 
Drilling Contractors (IADC) guidelines IADC-DCCS-1/1991 describes a 
special-purpose cable and, therefore, this standard should be referred 
to in the industrial systems subpart. One requested the removal of the 
standard altogether.
    The standard is referred to in Sec. 111.60-1 because both 
Sec. 111.60-1 and the standard concern cable construction details.
    (4) Several comments requested that the Coast Guard include 
acceptance of IEC 92-350 cable.
    This type of cable is not included because IEC 92-350 is not now a 
reaffirmed publication. In addition, as a result of tests conducted for 
the Coast Guard, this cable failed to meet all of the performance 
criteria in IEEE Std 45.
    (5) One comment pointed out that IEC 92-3 does not require any 
markings and suggested that this section include a marking or labeling 
requirement to avoid confusion and promote consistency.
    Paragraph (d) has been revised to include a marking requirement.
    (6) Several comments suggested that the only reliable way to ensure 
that cable meets the referenced specifications would be to include 
wording requiring independent laboratory compliances testing for these 
products.
    Third party testing of marine shipboard cable is being considered 
for inclusion into the 1996 revision IEEE Std 45 which will be 
incorporated by reference into the CFR when the standard is published 
by the IEEE.
    Sec. 111.60-2. One comment pointed out that the 1983 IEEE Std 45 
neither requires nor modifies IEEE Std 1202. Additionally, it suggests 
the inclusion of Canadian Standards Association (CSA) FT-4.
    This section has been revised to remove the modification language. 
CSA FT-4 is under review for consideration.
    Sec. 111.60-3. Several comments suggested the need to address 
cables exposed to vibration, festooning, and repeated flexing.
    Paragraph (d), which references cables for special applications in 
IEEE Std 45 section 19.6.5, has been added to this section.
    Sec. 111.60-4. One comment pointed out that 2.08 mm\2\ does not 
correlate to #14 AWG.
    The metric equivalent has been revised in accordance with IEEE Std 
45 table A6.
    Sec. 111.60-6. One comment suggested several standards to be 
referenced relative to fiber optic cable and its fire load.
    This concern is adequately addressed in paragraph (b) which refers 
to Sec. 111.60-2 concerning specialty cable.
    Sec. 111.60-13. Several comments requested reinserting UL 62 and 
adding article 400 of the NEC as references in paragraph (a).
    Paragraph (a) has been revised accordingly.
    Sec. 111.60-17. Several comments recommended that the thread-
cutting type of connector is likely to sever strands of stranded-copper 
conductors and, therefore, should not be allowed. Several other 
comments recommended not allowing the use of the twist-on type of 
connectors.
    If properly installed and secured, the twist-on type of connector, 
used in an enclosure, is suitable for joining relatively small loads to 
the supply cable. The reference to thread-cutting type of connectors 
has been removed.
    Sec. 111.60-19. Several comments suggested prohibiting cable 
splices in all Class I, Division 1, locations.
    Splices are prohibited in all hazardous locations, except that 
splices in intrinsically safe systems are allowed under paragraph (a).
    Sec. 111.60-23. Many comments were received either requesting a 
more liberal policy on the use of metal-clad (MC) cable on vessels or 
recommending its complete prohibition as being totally unsuitable for 
shipboard and MODU installations. This extensive range of comments 
necessitated a complete review and revision of the MC cable section. In 
the process of revising this section, the Coast Guard reviewed each 
comment and tried to balance the conflicting views to provide a 
solution that would allow MC cable to be used safely.
    Based upon on-site observations, the Coast Guard determined that 
limited use of MC cable may be allowed. New Sec. 111.60-23 is a 
restatement of the policy developed by the Coast Guard since January 
1991.
    Sec. 111.70-1. (1) Several comments suggested deleting ``-94'' 
after ``ABS Rules, Part 4/5.87'' in paragraph (a).
    This typographical error has been corrected and the word ``Part'' 
has been replaced with the correct word ``sections''.
    (2) One comment recommended deleting the reference to subpart 
111.35 in paragraph (a)(2) and citing ABS Rules directly.
    The reference remains as proposed to avoid the more lengthy cross-
reference to ABS Rules each time an electrical propulsion installation 
is mentioned throughout the subchapter.
    (3) One comment recommended that ABS Rule 4/5.115.6 be included in 
paragraph (a) due to the NPRM's deleting the NEC article 430.
    Paragraph (a) has been revised accordingly with an additional 
cross-reference to ABS MODU Rules.
    Sec. 111.70-3. (1) Several comments noted that the incorrect NEMA 
standard was cited in paragraph (a).
    The correct standard is now cited.
    (2) One comment suggested that enclosures in a hazardous location 
must meet subpart 111.105 in addition to the other stated standards.
    Paragraph (a) has been revised accordingly.
    (3) One comment suggested that schematics and wiring diagrams need 
only be available on the vessel and not necessarily on the door of each 
controller.
    The requirement is retained for safety reasons. This information 
must be immediately available in emergency situations.
    (4) One comment suggested replacing ``and'' with ``or'' and 
deleting (v) and (vii) in paragraph (d)(1).
    The comment provided no reason for these changes. Therefore, the 
paragraph remains unchanged.
    Sec. 111.75-16. One comment requested replacing the prescriptive 
reference to

[[Page 28266]]

``floodlights'' with the more performance-oriented term ``lighting''.
    The Coast Guard agrees and has amended this section accordingly.
    Sec. 111.75-17. (1) One comment started that the requirement for 
flexible cables and receptacles is unnecessarily restrictive and 
suggested that permanent installations be addressed in paragraphs 
(e)(e) and (e)(4).
    The paragraphs has been revised accordingly.
    (2) One comment recommended including alternative wording in the 
labeling requirement in paragraph (d)(3)(1) to allow for the registered 
certification mark instead of the name of the independent laboratory 
which tested the figure.
    Paragraph (d)(3)(1) has been revised accordingly.
    (3) One comment suggested that, in paragraph (d)(3)(i), 
``independent laboratory, accepted by the Commandant'' be replaced by 
``accepted independent laboratory'' and that ``UL 1104'' be replaced by 
``this standard''.
    The directions properly express the intent of the requirement and 
the wording remains as published in the NPRM.
    (4) One comment stated that navigation lights should also meet 
international standards (COLREGS).
    The reference in paragraph (d)(1) to ``applicable navigation 
rules'' includes COLREGS as well as Inland Navigation Rules, as 
applicable.
    (5) One comment suggested that specific requirements for battery-
operated navigation lights and additional labeling information be 
included in paragraph (d).
    Paragraphs (d)(3)(iv), (v), and (vi) were added to provide 
essential information needed by marine inspectors to determine the 
fixture's suitability for vessel type and location.
    (6) One comment suggested the inclusion of specific photometric 
requirements for battery powered navigation lights.
    This concern is currently under consideration by the Navigation 
Safety Advisory Committee (NAVSAC) and the Coast Guard is awaiting 
NAVSAC's recommendations before further rulemaking on this issue.
    Sec. 111.75-20. (1) Several comments requested clarification of the 
word ``certified'' in paragraph (a) and the words ``self-certified'' 
and ``listing is not required'' in paragraph (e).
    These words have been replaced with the requirement that the 
lighting fixtures meet the stated standards.
    (2) One comment objected to the incorporation of the UL standards 
in the proposal on the grounds that they are prescriptive and non-
consensus-based.
    The Coast Guard has determined that, in this, instance, the UL 
standards referenced adequately address the equipment.
    (3) One questioned the proposed environmental testing requirements 
for luminaries (lighting fixtures).
    The comment offered no explanation. Coast Guard accepts either 
standard as an option.
    (4) On May 1, 1996, UL announced the publication of the Marine 
Supplements to the Standard for Fluorescent Lighting Fixtures, UL 1570; 
the Standard for Incandescent Lighting Fixtures, UL 1571; and the 
Standard for High Intensity Discharge Lighting Fixtures, UL 1572. The 
requirements in these supplements are effective May 3, 1999, and will 
replace the requirements of UL 595. UL 595 will be withdrawn at that 
time. Between May 1, 1996, and May 3, 1999, UL is allowing compliance 
testing of fixtures to either the new series of standards or UL 595. 
The Coast Guard accepts either regimen.
    Sec. 111.77-3. One comment suggested removing the word 
``internationally'' because both international and domestic standards 
are appropriate.
    This section has been amended by removing ``internationally'' and 
by specifying UL safety and construction standards. The use of other 
domestic and international standards may be requested under the 
equivalency provision in Sec. 110.20-1.
    Sec. 111.79-1. (1) One comment suggested deleting the last sentence 
of paragraph (d), because the requirement is redundant, and moving the 
requirement of Sec. 111.79-7 to a more appropriate location in new 
paragraph (e) of Sec. 111.79-1.
    The changes have been made accordingly.
    (2) One comment indicated that the change in the spacing of 
receptacles in paragraph (b) went beyond recognized classification 
society and international standards.
    The Coast Guard agrees and has amended the section accordingly.
    Sec. 111.79-5. One comment expressed concern that adding the words 
``suitable for the environment'' to Sec. 111.79-1(d) and removing 
Sec. 111.79-5 would allow misinterpretation and create a safety 
problem.
    Although ``suitable for the environment'' should provide sufficient 
guidance, paragraph (d) has been revised to include a specific cross-
reference to Sec. 111.01-9, Degrees of protection.
    Sec. 111.81-1. (1) Several comments suggested replacing ``section 
370'' with ``article 370'', in paragraph (d), to be consistent with the 
terminology used in the document referred to (the NEC).
    The recommended change has been made in this and other locations in 
the rulemaking.
    (2) Several comments noted that the requirements in Secs. 111.81-7 
and 111.81-9 should be consolidated in Sec. 111.8-1.
    This change has been made and Secs. 111.81-7 and 111.81-9 have been 
consolidated into Sec. 111.81-1.
    Sec. 111.85-1. One comment recommended the removal of proposed 
paragraph (b) because this equipment could fail and create an arc 
without necessarily reaching the ignition temperature of the oil or 
vapor.
    The paragraph has been removed.
    Sec. 111.87-3. Several comments pointed out that third-party 
certification may place an undue hardship on heater manufacturers.
    Paragraph (a) has been revised to remove the proposed third-party 
testing requirement. Also, the words ``UL safety and construction 
standards'' have been added.
    Sec. 111.95-1. One comment stated that the list of provisions 
paragraph (b) is incomplete.
    Paragraph (b) has been amended to avoid specifying individual 
provisions.
    Sec. 111.99-5. One comment stated that there are no requirements to 
install a holding and release system on fire doors and that the holding 
force and power interruption requirements in paragraph (e), for systems 
which are installed, exceed any SOLAS 74 requirement.
    The 1992 Fire Safety Amendments to SOLAS 74 address fire door 
release systems in regulation II-2/30.4.3. This subpart has been 
revised to cross-reference the SOLAS 74 regulation.
    Sec. 111.105-5. (1) Several comments questioned if the intend of 
this section was to prohibit the use of both NEC and IEC approved 
equipment in the same space.
    The intent of this section is to ensure that proper and safe 
equipment is used in hazardous locations. This section has been amended 
to allow safe combinations of both types.
    (2) Several comments pointed out the need for the word ``location'' 
after the word ``hazardous'' in the second sentence.
    The sentence has been revised accordingly.
    (3) One comment recommended the inclusion of API RP 505 as a 
criterion for system integrity.
    The standard is currently under consideration for incorporation.
    (4) One comment requested clarification of this section's effect on 
the application of the NEC and IEC

[[Page 28267]]

methods of classification in any one hazardous location and between 
similar areas aboard the same vessel.
    Any given location is subject to more than one classification. For 
example, a specific cargo oil tank may be classified as a Class I, 
Division 1, location under the NEC and a Zone 0 location under the IEC 
system. Electrical equipment approved for Class I, Division 1 
(intrinsically safe) or approved for Zone 0 (I<INF>a) may be used.
    Sec. 111.105-9. Several comments considered this section 
unnecessary and redundant in light of Sec. 111.105-7.
    Both Secs. 111.105-7 and 111.105-9 have been revised. Section 
111.105-9 is considered necessary due to the term ``explosionproof'' 
having a different but related meaning in the IEC system.
    Sec. 111.105-11. (1) Several comments pointed out that either 
distance separation or a partition is an acceptable practice for 
intrinsically safe circuits.
    This section has been revised accordingly.
    (2) One comment pointed out that paragraph (a) referred more 
specifically to intrinsically safe ``components'' instead of 
``systems''; that the reference to Sec. 111.105-7 was redundant; and 
that other changes are needed to provide clarity.
    The section has been revised accordingly.
    Sec. 111.105-15. (1) One comment pointed out that the preamble to 
the NPRM stated that electrical installations in hazardous locations 
will continue to meet explosionproof/intrinsically safe requirements 
but that other allowances are made in Sec. 111.105-15 for additional 
locations.
    The comment was correct in recognizing that methods other than 
``explosionproof'' or ``intrinsically safe'' are included in the text. 
The methods of protection listed in Sec. 111.105-15 are acceptable in 
addition to ``explosionproof'' or ``intrinsically safe.''
    (2) One comment suggested providing acceptable alternative 
standards based on the NEC in paragraphs (b) and (d).
    Paragraph (b) has been revised accordingly; other equivalent types 
of protection are being evaluated.
    (3) One comment recommended removing paragraph (b0 because its 
requirements are redundant.
    This section has been revised accordingly.
    Sec. 111.105-17. (1) Several comments expressed concern about 
deleting, from paragraph (a), the requirements for armored cable in 
hazardous locations.
    Paragraph (a) has been revised to clarify that armored marine 
shipboard cable is required in Class I, Division 1 (Zone 0 and Zone 1) 
hazardous locations.
    (2) One comment pointed out that MI and SI type cables should be 
deleted because they are generally obsolete and are used in only highly 
specialized applications.
    These type cables have been retained to allow an option for those 
particular applications.
    (3) One comment suggested that the Class and Zone designations in 
paragraph (d) are incorrect.
    Class II and Class III (Zone Z or 10, and Zone Y or 11) refer to 
atmospheres containing dusts and flyings. Paragraph (d) has been 
slightly revised to clarify.
    Sec. 111.105-31. (1) Several comments pointed out that Appendix B 
does not appear in IEEE Std 45-1983 and that IEC Publication 92-502 
should be included as a reference for this section.
    This section has been revised as suggested.
    (2) Several comments requested the rationale of the requirements in 
new paragraphs (1)(3) and (1)(4).
    These requirements are consistent with ABS Rule 4/5.151.lb.
    Sec. 111.105-32. One comment suggested that the word ``Commandant'' 
in paragraph (c) be changed to ``Commanding Officer, Marine Safety 
Center''.
    Paragraph (c) has been revised to provide for concept approval by 
the Commandant (G-MSE) and plan approval by Commanding Officer, Marine 
Safety Center.
    Sec. 111.105-33. One comment recommended that a provision be added 
to paragraph (f) that loss-of-ventilation alarms be powered 
independently of the ventilator's power system consistent with the 
independency concept for vessels under 46 CFR 62.30-5.
    This change has been made to the MODU regulations in Sec. 108.185.
    Sec. 111.105-35. One comment recommended adding corresponding IEC 
Zone designations to the NEC locations specified in this section.
    These additions have been made.
    Sec. 111.105-39. Several comments suggested deleting the note to 
this section because it does not relate to the subject of the section.
    The note has been removed.
    Sec. 111.105-40. One comment suggested a vertical distance limit be 
added to paragraph (b) so that hazardous location classification is not 
extended to an unlimited height.
    The open deck of a roll-on/roll-off (RO/RO) vessel is not 
classified. The paragraph has been revised to address closed cargo 
spaces.
    Secs. 111.105-43 and 111.105-45. One comment recommended adding 
corresponding IEC Zone designations to the NEC locations specified in 
this section.
    These additions have been made.
    Sec. 111.105-47. One comment suggested that this section should not 
apply when the flashpoint of the flammable or combustible cargo is 
60 deg.C or more.
    This section has been removed and transferred to Sec. 111.105-
31(n).
    Sec. 111.107-1. (1) One comment noted that IEEE Std 383 referred to 
in paragraph (c)(2)(i) has been replaced with IEEE Std 1202.
    This paragraph has been changed accordingly.
    (2) One comment noted that paragraph (c) as proposed required 
compliance with (c) (1), (2), and (3) instead of (c) (1) and (2) or 
(c)(3).
    Paragraph (c) has been revised as noted.
    Sec. 112.05-1. One comment suggested removing ``only'' in paragraph 
(a) and adding, after ``emergency'', ``and those additional loads that 
may be authorized under paragraph (c) of this section.''
    Paragraph (a) has been revised as suggested.
    Sec. 112.05-5. Several comments requested clarification of the 
words ``any other machinery'' in paragraph (d).
    Paragraph (d) has been revised to clarify the words.
    Sec. 112.15-1. One comment recommended that the cross-references in 
the last sentence of paragraph (g) were informational only and, 
therefore, unnecessary.
    The last sentence has been removed.
    Sec. 112.15-5. (1) One comment suggested that the list of parts in 
paragraph (e) may not be complete.
    Paragraph (e) has been revised as suggested.
    (2) One comment suggested replacing ``a mobil offshore drilling 
unit'' in paragraph (m) with ``an offshore unit.''
    Paragraph (m) has been revised as suggested.
    Sec. 112.50-1. One comment suggested that the 45-second delay in 
paragraph (d) be aligned with proposed revision of NFPA Standard 301, 
which would require a 10-second delay.
    The 45-second delay is retained because this requirement is aligned 
with SOLAS 74.
    Sec. 112.50-3. One comment stated that paragraphs (f) and (g) have 
been superseded by proposed paragraph (a).
    Paragraphs (f) and (g) have been removed.
    Sec. 112.50-5. One comment recommended that the starting battery 
have a reserve starting capacity of at least three starts.
    The proposal already provides for this, either by means of the 
battery itself

[[Page 28268]]

or by means of the battery and a second source of starting energy.
    Sec. 113.05-7. Several comments addressed the subject of 
environmental testing of communication, alarm, control, and monitoring 
equipment.
    New Sec. 113.05-7, Environmental Testing, has been created in 
response to these concerns.
    Sec. 113.10-7. One comment recommended removing the specific 
degrees of ingress protection referred to in this section due to their 
excessive nature.
    The NEMA and IEC IP ratings of the connection boxes are retained 
because exceptional degrees of protection are required throughout part 
113 since these systems are emergency in nature. However, the 
``watertight'' requirements have been replaced with the less stringent 
``waterproof'' requirements.
    Sec. 113.10-9. One comment pointed out in paragraph (a) that, by 
requiring the second source of power for the fire detection system to 
be a battery, the Coast Guard is deviating from its present regulations 
and SOLAS 74, which allow the second source to be either the emergency 
source or a battery.
    Paragraph (a) has been revised to keep the present options and to 
define the source of power for the battery charger if used.
    Sec. 113.25-6. One comment suggested that, in paragraph (d), the 
Coast Guard cite the specific SOLAS 74 regulations for the power supply 
for the general alarm system.
    The section has been revised to refer to SOLAS 74, regulations II-
1/42, 11- 1/43, III/6, and III/50.
    Sec. 113.25-9. One comment suggested harmonizing our general alarm 
requirements in paragraphs (b) and (c) with NFPA 72 (National Fire 
Alarm Code). Another comment suggested harmonizing the section with the 
new IMO Lifesaving Appliances Code.
    Paragraph (c) has been revised according to the second suggestion. 
The sound level requirements have been moved from 113.25-9(c), 
concerning location of general emergency alarm signals, to paragraph 
(d) of Sec. 113.25-12, Alarm signals.
    Sec. 113.25-10. One comment noted that the prohibition against 
using red flashing or rotating beacons for purposes other than the 
general alarm seems to be in conflict with the IMO ``Code on Alarms and 
Indicators,'' which recommends red lights as supplemental visual alarms 
for fire alarm and fire-extinguishing medium release.
    Pending further consideration of the IMO Code, proposed paragraph 
(c) has been removed.
    Sec. 113.25-11. (1) One comment recommended removing specific 
degrees of ingress protection in paragraph (a) because the degree 
should be consistent with the location of the device.
    The NEMA and IEC IP ratings of the contact makers are retained 
because exceptional degrees of protection are required throughout part 
113 since these systems are emergency in nature. However, the 
``watertight'' requirements have been replaced with the less stringent 
``waterproof'' requirements.
    (2) One comment recommended revising the section to address SOLAS 
74-compliant digital systems that do not incorporate contact makers.
    Since the term ``contact maker'' refers to the primary initiating 
device and not the resultant audible device, it follows that every 
system, regardless of design, should employ some form of contact maker 
as a manual means to initiate the alarm.
    Sec. 113.25-12. One comment suggested replacing ``bells'' with the 
more common term ``audible devices'' and, in the process, deleting 
paragraph (b).
    The term ``bells'' has been removed and replaced with the SOLAS 74 
description ``general emergency alarm signal.'' Paragraph (b) has been 
deleted as its requirements are now included in paragraph (a).
    Sec. 113.30-1. One comment suggested not adding the words ``and 
each self-propelled mobile offshore drilling unit'' since MODU's are 
defined as vessels in Sec. 107.111.
    This change has been made accordingly.
    Sec. 113.30-3. One comment recommended that the section be revised 
to address all communication means that are in compliance with SOLAS 
74, regulations II-1/42, II-1/43, and III/6.4.
    This section has been revised as suggested.
    Sec. 113.30-5. Minor editorial changes were made to align this 
section with the changes made to 113.30-3.
    Sec. 113.30-20. One comment recommended that paragraph (b) be 
revised to require that only systems that do not have other effective 
means of station isolation during a fault have a cut-out switch on the 
navigating bridge.
    Paragraph (b) has been revised as suggested.
    Sec. 113.30-25. One comment recommended that paragraph (i) be 
revised to allow the option of cable routing through high fire-risk 
spaces if the cable meets the requirements of IEC 331. The use of this 
standard can lead to significant cost savings and more practical 
installations.
    Paragraph (i) has been revised accordingly.
    Sec. 113.35-5. One comment stated that the audible alarm signal in 
paragraph (e)(3) should not be able to be silenced but reduced in 
volume.
    This change has been accepted.
    Sec. 113.35-19. One comment suggested redesignating this section as 
Sec. 113.35-7 (which has been removed in this rule) because both 
Sec. 113.35-19 and Sec. 113.35-5 concern electric engine order 
telegraph systems.
    Section 113.35-19 has been redesignated accordingly.
    Sec. 113.40-10. One comment suggested that the requirement in 
paragraph (a) seemed extreme and questioned whether the system must 
have an entirely independent power source and whether it could be 
physically located in the same console as other systems.
    The proposed requirement that the power system be independent is 
retained because it is the intent that the power for a rudder angle 
indicator system be provided from a power supply circuit other than 
power circuits used for the equipment in paragraph (a). Paragraph (a) 
is revised to allow location in the same console.
    Subpart 113.43. One comment suggested that the requirement for a 
steering gear failure alarm be removed because it is excessive when 
compared to international safety standards and suggested that improved 
training could be initiated in place of this requirement to address the 
watchstander's response to steering gear failures.
    This requirement was established in direct response to a National 
Transportation Safety Board (NTSB) recommendation resulting from their 
investigation of the SEA WITCH/ESSO BRUSSELS collision in New York 
Harbor in 1974. Although improved crew training and related human 
factor consideration may help, the Coast Guard determined that both 
technological and non-technological solutions should not be considered 
to be mutually exclusive. With regard to human factors, the Coast Guard 
has found that even the best training, by itself, cannot account for 
the many variables contributing to human error. Proper and timely 
execution of steering orders is critical to safe vessel navigation. 
While training may assist in proper actions taken by the helmsman, the 
failure alarm is intended to provide the operator with a warning when 
the physical system does not respond as expected. This regulation is 
therefore being retained and the Coast Guard intends to introduce this 
system feature as a safety issue to be considered at IMO

[[Page 28269]]

for improving international regulations on steering system controls.
    Sec. 113.50-5. (1) Several comments discussed the prescriptive 
nature of the central amplifier-type system in paragraph (a) citing the 
many optional system configurations available.
    Paragraph (a) has been revised to allow alternative amplifier 
systems.
    (2) One comment suggested allowing for a combined public address, 
general alarm, and fire detecting and alarm system, as provided for in 
Navigation and Vessel Inspection Circular (NVIC) 2-89.
    Paragraph (a) has been changed accordingly.
    (3) One comment suggested adding a requirement from the IMO 
Lifesaving Appliance Code to protect the public address system from 
unauthorized use.
    Paragraph (a) has been revised as suggested.
    Sec. 113.50-10. (1) One comment suggested deleting the words 
``enables an officer on the bridge to broadcast'' as unnecessary 
prescriptive language.
    The words have been deleted. The requirement for the announcing 
station of the system to be on the bridge is retained in Sec. 113.50-
5(b).
    (2) One comment recommended removing the replacement for two-way 
communication in paragraph (b) because it appears to require a two-way 
communication as part of the public address system.
    Paragraph (b) has been deleted because two-way communication 
requirements are covered in subpart 113.30.
    Sec. 113.50-15. (1) Several comments recommended revising paragraph 
(b) to remove the prescriptive words ``directed aft.''
    Paragraph (b) has been revised as suggested by substituting a 
performance standard.
    (2) One comment suggested replacing table 113.50-15 with the 
requirements from the IMO Lifesaving Appliance Code.
    The table has been removed and the requirements for minimum sound 
levels from the IMO Lifesaving Appliance Code have been added to 
paragraph (c).
    Sec. 113.65-5. (1) One comment suggested removing the note 
following Sec. 113.65-5 as being out of date and merely a cross-
reference to other requirements for associated equipment.
    The note has been removed.
    Sec. 161.002-1. (1) Components of automatic fire detection systems, 
EN54 parts 1 through 11, published by the European Committee for 
Standardization (CEN) have been removed from this section because some 
of the documents obtained by the Coast Guard were in draft form. Once 
finalized, these documents will again be reviewed for inclusion.
    (2) This section has been conformed to the current format for 
incorporation by reference sections. Existing paragraph (b), left 
untouched by the NPRM, is removed by this rule. The existing paragraph 
required manufacturers to maintain a copy of certificates of approval 
and the material listed in proposed paragraph (a) (paragraph (b) in 
this rule). As the list of materials has grown, it is unnecessary for 
manufacturers to maintain a copy of all of these documents.
    (3) One comment suggested that American National Standards 
Institute (ANSI) be listed as a source of all incorporated materials.
    Though not all of the documents listed in Sec. 161.002-1 
(Incorporation by reference) are available from ANSI, some may be 
obtained from ANSI's address listed in Sec. 110.10-1.
    Sec. 161.002-4. (1) A cross-reference to subchapter J has been 
added to the end of paragraph (b)(1) because it has been deleted from 
Sec. 161.002-1 (Incorporation by reference) for formatting reasons.
    (2) One comment suggested removing paragraph (b)(3) because there 
is no justification for its inclusion.
    LR Test Specification Number 1 is an internationally accepted 
testing protocol for shipboard electrical and electronic equipment 
based upon various requirements of the IEC and is retained.
    (3) An option has been provided in paragraph (b)(3) to include 
table 4/11.1 of the ABS Rules.
    Sec. 161.002-10. One comment recommended that paragraphs (b)(1)(i) 
and (ii) be revised to clarify the term ``similar annunciating 
device.''
    Paragraph (b)(1) has been revised for clarification.
    Sec. 161.002-15. (1) One comment requested that ``aural'' be 
changed to ``audible.''
    This change has been made because it conforms to Factory Mutual 
terminology.
    (2) Proposed paragraph (b) has been removed because SOLAS 74 is 
already mentioned in Sec. 161.002-1.
    Sec. 161.002-17. This section has been aligned with equivalency 
provisions in other recent Coast Guard rulemakings.
    Subpart 161.004. One comment noted that subpart 161.004, which is 
removed, included Sec. 161.004-1 as well.
    This change has been made accordingly.

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. The material is available as indicated in 
that section.

Regulatory Evaluation

    This rule is not a significant regulatory action under section 3(f) 
of Executive Order 12866 and does not require an assessment of 
potential costs and benefits under section 6(a)(3) of that order. 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 has been prepared and is 
available in the docket for inspection or copying where indicated under 
``ADDRESSES.'' The Evaluation is summarized as follows.
    Most of the changes to the regulations are either editorial or 
update technical specifications to reflect 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 interim 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 evaluation in the preamble to the 
NPRM. The Coast Guard solicits cost data and comments regarding the 
economic impact of the changes made

[[Page 28270]]

since requirements were published in the NPRM.

Small Entities

    Under the Regulatory Flexibility Act (the Act) (5 U.S.C. 601 et 
seq.), the Coast Guard must consider the economic impact on small 
entities of a rule for which a general notice of proposed rulemaking is 
required. ``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 concerns of many small entities have been addressed by the 
incorporation of wide variety of national and international standards. 
This rule dramatically revises certain prescriptive requirements 
concerning the design, specification, and approval of electrical 
equipment and replaces them with performance-based requirements that 
incorporate national and international standards. Whenever possible, 
requirements have been adjusted to address the size of the vessel and, 
in some cases, relaxed for smaller vessels. Small entities that build 
or own vessels should experience reduced costs and potentially 
increased business opportunities due to the flexibility of requirements 
in these rules and the eliminating of regulatory burden.
    Therefore, the Coast Guard certifies under section 605(b) of the 
Act that this rule will not have a significant economic impact on a 
substantial number of small entities.

Collection of Information

    Under the Paperwork Reduction Act (44 U.S.C. 3501 et seq.), the 
Office of Management and Budget (OMB) reviews each rule that contains a 
collection-of-information requirement to determine whether the 
practical value of the information is worth the burden imposed by its 
collection. Collection-of-information requirements include reporting, 
recordkeeping, notification, and other, similar requirements. This rule 
contains collection-of-information requirements in subpart 110.25 of 
subchapter J and subpart 161.002 of subchapter Q.
    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.
    The collection-of-information requirements were submitted to the 
Department of Transportation on the following dates: February 6, 1996, 
for subchapter Q and February 26, 1996, for subchapter J. The 
requirements have not yet been approved by OMB under section 3504(h) of 
the Paperwork Reduction Act. When approved by OMB, notice of approval 
will be published in the Federal Register.

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.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 impacts 
on the marine environment. A ``Categorical Exclusion Determination'' is 
available in the docket for inspection or copying where indicated under 
ADDRESSES.

    (c) Conversions, such as the addition of a midbody or a change in 
the service of the vessel, are handled on a case-by-case basis by 
Commandant (G-MOC).
    8. Section 110.10-1 is revised to read as follows:


Sec. 110.10-1  Incorporation by reference.

    (a) Certain material is incorporated by reference into this 
subchapter with the approval of the Director of the Federal Register 
under 5 U.S.C. 552(a) and 1 CFR part 51. To enforce any edition other 
than that specified in paragraph (b) of this section, the Coast Guard 
must publish notice of change in the Federal Register; and the material 
must be available to the public. All approved material is available for 
inspection at the Office of the Federal Register, 800 North Capitol

operational conditions. Any vessel speed change or throttle movement 
must not cause a ship's service load power interruption.
    (e) Vessels with electric propulsion that have two or more 
constant-voltage generators which supply both ship's service and 
propulsion power do not need additional ship's service generators
