[CGD 94–108]

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industry, purge obsolete and out-of-date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

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 Guardinspected 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
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 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 § 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

§ 108.170. (1) One comment indicated

that this section is duplicated in

§ 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.

§ 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).

§ 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.

§ 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 § 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 § 111.81–13(a)

but this section is removed.

UL 50 is now cited in § 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 §§ 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

§ 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 § 110.10–1(a), only

the edition listed in § 110.10–1(b) can be

enforced. The Coast Guard will consider
28262 Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations

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 § 161.002–17, as

providing an equivalent level of safety.

(13) Several comments suggested

incorporating ABS MODU Rules into

the following sections: §§ 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 § 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.

§ 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 § 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

§ 113.30–5(d).

‘‘Emergency squad’’ has been

reinserted in § 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.

§ 110.20–1. This section has been

aligned with equivalency provisions in

other recent Coast Guard rulemakings.

§ 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 selfcertification 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.

§ 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.

§ 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.

§ 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.

§ 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 § 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.

§ 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.

§ 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.

§ 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.

§ 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.
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 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.

§ 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.

§ 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.

§§ 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 § 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 § 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

§ 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.

§ 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.

§ 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.

§ 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.

§ 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.

§ 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 § 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.

§ 111.10–7. One comment stated that

paragraph (b) duplicates the provisions

of § 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.

§ 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 § 111.10–

4(b). Propulsion accounts for only a

portion of the loads. The transformer

requirements are retained for non-selfpropelled 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.

§ 111.12–11. (1) Several comments

recommended replacing the words

‘‘inverse time,’’ in paragraph (c)(1), with

the word ‘‘longtime’’ to be consistent
28264 Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations

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.

§ 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.

§ 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.

§ 111.15–20. One comment suggested

a minor wording order change in

paragraph (c) for clarity.

Paragraph (c) has been revised as

suggested.

§ 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.

§ 111.30–5. (1) One comment

observed that the wire sizes mentioned

in the reference of paragraph (a) differed

from those cited in § 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 § 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.

§ 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.

§ 111.30–24. One comment requested

that the exclusion for a non-selfpropelled MODU be expanded to

include flotating Outer Continental

Shelf (OCS) facilities.

This section has been revised to

extend the exclusion to a non-selfpropelled floating Outer Continental

Shelf (OCS) facility.

§ 111.30–29. (1) One comment

pointed out that proposed paragraph (i)

was merely a repetition of the

requirement in § 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.

§ 111.30–31. One comment

recommended that § 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.

§ 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 §§ 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 §§ 111.01–7 and

111.01–9.

§ 111.40–7. One comment suggested

rewriting this section for ease of

comprehension.

This section has been rewritten as

suggested, without substantive change.

§ 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.

§ 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.

§ 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.

§ 111.53–1. One comment suggested

replacing ‘‘§ 110.35–1’’ in paragraph

(a)(3) with ‘‘part 159’’ because § 110.35–

1 merely cites part 159 of this chapter.

‘‘Independent laboratory’’, as now

defined in § 110.15–1, references part

159 and subpart 110.35 has been

removed.

§ 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.
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 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.

§ 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

§ 110.20–1.

(2) Many comments requested that the

75°C requirement in paragraph (c)(6) be

changed to 90°C, as allowed in USA/

Canadian binational shipboard cable

standard UL 1309/CSA C22.2 No. 245.

The requirement for 75° 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 specialpurpose 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

§ 111.60–1 because both § 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.

§ 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.

§ 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.

§ 111.60–4. One comment pointed out

that 2.08 mm2 does not correlate to #14

AWG.

The metric equivalent has been

revised in accordance with IEEE Std 45

table A6.

§ 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

§ 111.60–2 concerning specialty cable.

§ 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.

§ 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.

§ 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).

§ 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

§ 111.60–23 is a restatement of the

policy developed by the Coast Guard

since January 1991.

§ 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 crossreference to ABS MODU Rules.

§ 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.

§ 111.75–16. One comment requested

replacing the prescriptive reference to
28266 Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations

‘‘floodlights’’ with the more

performance-oriented term ‘‘lighting’’.

The Coast Guard agrees and has

amended this section accordingly.

§ 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 batteryoperated 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.

§ 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.

§ 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 § 110.20–1.

§ 111.79–1. (1) One comment

suggested deleting the last sentence of

paragraph (d), because the requirement

is redundant, and moving the

requirement of § 111.79–7 to a more

appropriate location in new paragraph

(e) of § 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.

§ 111.79–5. One comment expressed

concern that adding the words ‘‘suitable

for the environment’’ to § 111.79–1(d)

and removing § 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 crossreference to § 111.01–9, Degrees of

protection.

§ 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 §§ 111.81–7 and

111.81–9 should be consolidated in

§ 111.8–1.

This change has been made and

§§ 111.81–7 and 111.81–9 have been

consolidated into § 111.81–1.

§ 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.

§ 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.

§ 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.

§ 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 crossreference the SOLAS 74 regulation.

§ 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
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 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 (Ia) may be used.

§ 111.105–9. Several comments

considered this section unnecessary and

redundant in light of § 111.105–7.

Both §§ 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.

§ 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 § 111.105–7 was redundant; and that

other changes are needed to provide

clarity.

The section has been revised

accordingly.

§ 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 § 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 § 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.

§ 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.

§ 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.

§ 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.

§ 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 § 108.185.

§ 111.105–35. One comment

recommended adding corresponding

IEC Zone designations to the NEC

locations specified in this section.

These additions have been made.

§ 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.

§ 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.

§§ 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.

§ 111.105–47. One comment suggested

that this section should not apply when

the flashpoint of the flammable or

combustible cargo is 60°C or more.

This section has been removed and

transferred to § 111.105–31(n).

§ 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.

§ 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.

§ 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.

§ 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.

§ 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.

§ 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.

§ 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.

§ 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
28268 Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations

or by means of the battery and a second

source of starting energy.

§ 113.05–7. Several comments

addressed the subject of environmental

testing of communication, alarm,

control, and monitoring equipment.

New § 113.05–7, Environmental

Testing, has been created in response to

these concerns.

§ 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.

§ 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.

§ 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.

§ 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 § 113.25–12,

Alarm signals.

§ 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 fireextinguishing medium release.

Pending further consideration of the

IMO Code, proposed paragraph (c) has

been removed.

§ 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.

§ 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).

§ 113.30–1. One comment suggested

not adding the words ‘‘and each selfpropelled mobile offshore drilling unit’’

since MODU’s are defined as vessels in

§ 107.111.

This change has been made

accordingly.

§ 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.

§ 113.30–5. Minor editorial changes

were made to align this section with the

changes made to 113.30–3.

§ 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.

§ 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.

§ 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.

§ 113.35–19. One comment suggested

redesignating this section as § 113.35–7

(which has been removed in this rule)

because both § 113.35–19 and § 113.35–

5 concern electric engine order

telegraph systems.

Section 113.35–19 has been

redesignated accordingly.

§ 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
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 28269

for improving international regulations

on steering system controls.

§ 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.

§ 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 § 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.

§ 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).

§ 113.65–5. (1) One comment

suggested removing the note following

§ 113.65–5 as being out of date and

merely a cross-reference to other

requirements for associated equipment.

The note has been removed.

§ 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 § 161.002–1 (Incorporation by

reference) are available from ANSI,

some may be obtained from ANSI’s

address listed in § 110.10–1.

§ 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 § 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.

§ 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.

§ 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 § 161.002–1.

§ 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 § 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 §§ 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 costbenefit 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
28270 Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations

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-ofinformation requirement to determine

whether the practical value of the

information is worth the burden

imposed by its collection. Collection-ofinformation 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.

microphones and loudspeakers

connected through an amplifier. If a

decentralized-type system is used, its

overall performance must not be

affected by the failure of a single call

station. This system may be combined

with the general emergency alarm and

fire detecting and alarm systems. The

public address system must be protected

against unauthorized use.

(b) The announcing station must be

located adjacent to the general

emergency alarm contact maker on the

navigating bridge.

(c) There must be a means to silence

all other audio distribution systems at

the announcing station.

(d) The system may be arranged to

allow broadcasting separately to, or to

any combination of, various areas on the

vessel. If the amplifier system is used

for the general emergency alarm

required by subpart 113.25 of this part,

the operation of a general emergency

alarm contact maker must activate all

speakers in the system, except that a

separate crew alarm may be used as

allowed by § 113.25–5(e)(2).

(e) The amplifier, and any device used

to produce the general emergency alarm

signal, must be provided in duplicate.

(f) The power supply must be in

accordance with the requirements of

§§ 113.25–6 and 113.25–7.

(g) Each electrical subsystem in a

weather location must be watertight or

in a watertight enclosure (NEMA 250

Type 6 or 6P or IEC IP 67).

204. Section 113.50–10 is added to

read as follows:

§ 113.50–10 Additional requirements for

passenger vessels.

Each passenger vessel must have a

public address system capable of

broadcasting separately or collectively

to the following stations:

(a) Survival craft stations, port.

(b) Survival craft stations, starboard.

(c) Survival craft embarkation

stations, port.
Federal Register / Vol. 61, No. 108 / Tuesday, June 4, 1996 / Rules and Regulations 28291

(d) Survival craft embarkation

stations, starboard.

(e) Public spaces used for passenger

assembly points.

(f) Crew quarters.

(g) Accommodation spaces and

service spaces.

205. In § 113.50–15, the section

heading and paragraphs (a) through (d)

are revised to read as follows and

paragraph (e) and table 113.50–15 are

removed:

§ 113.50–15 Loudspeakers.

(a) Loudspeakers must be located to

eliminate feedback or other interference

which would degrade communications.

(b) Loudspeakers must be located to

provide intelligible and audible oneway communication throughout the

vessel. Weatherdeck loudspeakers must

be watertight and suitably protected

from the effects of the wind and seas.

(c) There must be a sufficient number

of loudspeakers throughout the vessel.

The public address system must be

installed with regard to acoustically

marginal conditions and not require any

action from the addressee. With the

vessel underway in normal conditions,

the minimum sound pressure levels for

broadcasting emergency announcements

must be—

(1) In interior spaces, 75 dB(A) or, if

the background noise level exceeds 75

dB(A), then at least 20 dB(A) above

maximum background noise level; and

(2) In exterior spaces, 80 dB(A) or, if

the background noise level exceeds 80

dB(A), then at least 15 dB(A) above

maximum background noise level.

(d) Loudspeakers must not have

external volume controls or local cutout

switches.

206. Section 113.50–20 is revised to

read as follows:

§ 113.50–20 Distribution of cable runs.

(a) Each system must have a feeder

distribution panel to divide the system

into the necessary number of zone

feeders. Where, because of the

arrangement of the vessel, only one zone

feeder is necessary, a branch circuit

distribution panel must be used.

(b) The feeder distribution panel must

be in an enclosed space next to the

public address system power supply.

(c) Each system must have at least one

feeder for each vertical fire zone.

(d) Each system must have one or

more branch circuit distribution panels

for each zone feeder, with at least one

branch circuit for each deck level. The

distribution panel must be above the

uppermost continuous deck, in the zone

served, and there must be no disconnect

switches for the branch circuits.

(e) A branch circuit must not supply

speakers on more than one deck level,

except for a single branch circuit

supplying all levels of a single space if

all other requirements of this section are

met.

(f) On a vessel not divided into

vertical fire zones by main vertical fire

bulkheads, the vessel must be divided

into vertical zones not more than 40

meters (131 feet) long. There must be a

feeder for each of these zones.

(g) Feeders and branch circuit cables

must be in passageways. They must not

be in staterooms, lockers, galleys, or

machinery spaces, unless it is necessary

to supply public address speakers in

those spaces.
