    -----------------------------------------------------------------------
    
    SUMMARY: As part of the President's Regulatory Reinvention Initiative, 
    the Coast Guard is amending its electrical engineering regulations to 
    reduce the regulatory burden on the marine industry, purge obsolete and 
    out-of-date regulations, and eliminate requirements that create an 
    unwarranted differential between domestic rules and international 
    standards. This rulemaking harmonizes, where possible, the electrical 
    engineering regulations with recent amendments to the International 
    Convention for the Safety of Life at Sea, 1974, as amended. 
    Additionally, this rulemaking dramatically revises certain prescriptive 
    electrical equipment design, specification, and approval requirements 
    and replaces them with performance-based requirements that incorporate 
    international standards.
    
    DATES: This final rule is effective June 16, 1997. The incorporation by 
    reference of certain publications listed in the rule is approved by the 
    Director of the Federal Register on June 16, 1997.
    
    ADDRESSES: Documents as indicated in this preamble are available for 
    inspection or copying at the office of the Executive Secretary, Marine 
    Safety Council (G-LRA/3406), U.S. Coast Guard Headquarters, 2100 Second 
    Street SW., room 3406, Washington, DC 20593-0001, between 9:30 a.m. and

    SUPPLEMENTARY INFORMATION:
    
    Regulatory History
    
        On February 2, 1996, the Coast Guard published a notice of proposed 
    rulemaking (NPRM) entitled ``Electrical Engineering Requirements for 
    Merchant Vessels'' in the Federal Register (61 FR 4132). There were two 
    correction notices published for the NPRM on February 23, 1996 (61 FR 
    7050), and March 5, 1996 (61 FR 8539). The Coast Guard received 45 
    letters commenting on the proposal. As a result of requests from a 
    national trade association, a notice was published on February 26, 1996 
    (61 FR 7090), extending the comment period from March 18, 1996, to 
    April 2, 1996, and announcing a public meeting on March 25, 1996. Over 
    20 persons attended the meeting and 9 commented on the NPRM. A 
    recording and summary of the meeting are in the rulemaking docket. On 
    June 4, 1996, the Coast Guard published an interim rule in the Federal 
    Register (61 FR 28260).
        Correction notices were published on June 26, 1996 (61 FR 33045), 
    July 3, 1996 (61 FR 34927), July 11, 1996 (61 FR 36608), July 12, 1996 
    (61 FR 36786), July 30, 1996 (61 FR 39695), and September 23, 1996 (61 
    FR 49691), in the Federal Register. Also, the Coast Guard published a 
    notice of policy on October 4, 1996 (61 FR 51789), in the Federal 
    Register. The Coast Guard received 30 letters commenting on the interim 
    rule. No public meeting was requested, and none was held.
    
    Drafting Information
    
        The principal persons involved in drafting this document are Mr. 
    Gerald P. Miante, Office of Design and Engineering (G-MSE-3), and Mr. 
    Stephen H. Barber, Project Counsel, Office of Chief Counsel.
    
    Purpose
    
        Under the authorities cited in the ``Authority'' section for each 
    part amended, the Coast Guard is amending its electrical engineering 
    and equipment regulations for certain Coast Guard-inspected vessels in 
    46 CFR chapter I, subchapters I-A, J, and Q to accomplish the 
    following:
        (1) To reduce the regulatory burden on the marine industry by 
    eliminating obsolete and unnecessary regulations and by clarifying the 
    remaining ones. This objective is consistent with the President's 
    Regulatory Reinvention Initiative and the Coast Guard's regulatory 
    reform program.
        (2) To replace, where appropriate, requirements that are 
    prescriptive in nature with performance-based requirements that 
    incorporate national or international standards and allow increased 
    flexibility for small businesses.
        (3) To eliminate requirements that create an unwarranted 
    differential between domestic rules and international standards. This 
    rulemaking harmonizes, where possible, the electrical engineering 
    regulations with amendments to the International Convention for the 
    Safety of Life at Sea, 1974, (SOLAS 74) since the electrical 
    engineering regulations were last revised in 1982.
        (4) To address comments received from the marine industry and from 
    Coast Guard field and inspection offices.
        This rulemaking is intended to serve the needs of industry while 
    maintaining a comparable level of safety.
    
    Discussion of Comments and Changes
    
        The following is a summary of the comments received and the changes 
    made to the regulatory text since the interim rule was published. The 
    items are grouped first by those that address a general issue, then by 
    those that relate to a specific provision in the text.
    
    I. General Comments.
    
        (1) Several comments congratulated the Coast Guard for its revision 
    of subchapter J which offers the manufacturers more flexibility, 
    increases clarity of the regulations and enhances safety of U.S. flag 
    vessels. It was observed that the revision process reflects a lot of 
    ``hard work and good common sense.''
        (2) As in response to the NPRM, a number of comments recommended 
    changes that may require further consideration by the Coast Guard. 
    Several comments recommended that certain other standards be referenced 
    in the regulations as replacements for, or options to, those cited in 
    the interim rule. However, not all changes could be incorporated at 
    this final rule stage, due to the complexity of the requests or the 
    necessity to allow the public an opportunity to comment on new 
    requirements. Several additional standards for incorporation by 
    reference are included in this final rule.
        The Coast Guard has a long-range plan to broaden the use of 
    acceptable standards. Until those standards are incorporated into the 
    regulations, any vessel owner or operator who desires to employ a 
    fitting, material, apparatus, equipment, or arrangement other than that 
    required by this subchapter may submit a request using the equivalency 
    provision in Sec. 110.20-1.
    
    Items the Coast Guard may consider for a subsequent rulemaking 
    include--
    
        (a) Incorporation of the new Institute of Electronic and Electrical 
    Engineers (IEEE) Std 45, when approved by the IEEE standards board and 
    published;
        (b) Addition of a requirement that all manufacturer's conducting 
    self-certification should be International Organization for 
    Standardization (ISO) 9001 registered;
    
    [[Page 23895]]
    
        (c) Incorporation of performance-based inclination criteria into 
    Sec. 111.01-19;
        (d) Consideration of requirements for high impedance grounding 
    systems to be added to Sec. 111.05-19;
        (e) Establishing a new subpart that would address the necessary 
    supply of clean, uninterrupted power for modern AC-powered, solid-state 
    equipment, which would complement the requirements of Secs. 111.15-3 
    and 111.20-1;
        (f) Addition of a ventilation alarm requirement to Sec. 
    111.35-1.
        (g) Prohibition of screw-in, porcelain or glass-cap fuses in 
    subpart 111.53;
        (h) Incorporation of new standards that provide guidance for high 
    voltage cable in Sec. 111.60-1(e);
        (i) Incorporation of the Canadian Standards Association
        (CSA) flame test CSA FT-4 either as another option or in place of 
    American National Standards Institute/Underwriters Laboratories (ANSI/
    UL) 1581 test VW-1 in Secs. 111.60-2 and 111.30-19(b)(4);
        (j) Incorporation of Underwriters Laboratories (UL) 2225 into 
    Sec. 111.60-23(h) to provide guidance on the use of metal-clad (Type 
    MC) cable in hazardous (classified) locations;
        (k) Incorporation of Illuminating Engineers Society
        (IES) Recommended Practice (RP) 12 for marine lighting in Sec. 
    111.75-15(c);
        (l) Permission of third-party testing for lighting, appliances, oil 
    immersion heaters, and electric heaters in Secs. 111.75-20, 111.85-1, 
    and 111.87-3;
        (m) Incorporation of International Electrotechnical
        Commission (IEC) 1892 in Sec. 111.105-5 for electrical 
    installations aboard mobile offshore drilling units (MODU's) and 
    floating platforms;
        (n) Incorporation of pump room ventilation and monitoring 
    requirements of American Bureau of Shipping (ABS), Rules for Building 
    and Classing Steel Vessels, section 4/5.151.6 into Sec. 111.105-31;
        (o) Replacing IEC 332-3, Category A flame test with IEC 332-3, 
    Category A/F in Sec. 111.107-1;
        (p) Restricting the color red for general emergency or fire alarms 
    only in Sec. 113.25-10;
        (q) Application of the cable routing and fire testing requirement 
    of Sec. 113.30-25(i) to all safety related circuits in part 113;
        (r) Incorporation of additional requirements in Sec. 
    113.50-20 to align the regulations with the International Maritime 
    Organization (IMO) Code of Alarms and Indicators; nd
        (s) Establishing a new subpart 113.70 for gas detection systems.
        (3) A number of comments commended the Coast Guard's effort to 
    streamline its electrical regulations and incorporate industry 
    standards, both domestic and international.
        Consistent with the President's Regulatory Reinvention Initiative, 
    the Coast Guard is taking this approach in all its rulemaking projects.
        (4) Two comments voiced several specific concerns and requested 
    extending the effective date of the interim rule by six months to allow 
    the U.S. shipbuilding community an opportunity to compile detailed 
    comments and suggestions regarding the change. Additionally, the 
    comment specified major concerns relating to degree of protection 
    requirements for enclosures, ambient temperatures for equipment, ground 
    detection regulation, and marine battery installations.
        In response, the Coast Guard, after a detailed analysis of these 
    concerns, determined that the extension of the comment period was 
    unnecessary. In response to the comment's specific concerns and until 
    this final rule could be finalized, the Coast Guard published a notice 
    of policy for interim rule (61 FR 51789; October 4, 1996). This policy 
    notice pointed out that persons wishing to apply a provision from the 
    1996 draft of IEEE Std 45 or the 1996 ABS Rules for Building and 
    Classing Steel Vessels instead of a provision in the interim rule could 
    submit, for approval on a case-by-case basis, a request under the 
    equivalency provisions in the interim rule.
        (5) One comment requested clarification on what standards are 
    approved for incorporation by reference and who determines if a 
    standard is approved.
        The Coast Guard determines which standards are acceptable for 
    incorporation by reference. In order to use a system arrangement or 
    individual piece of equipment that does not meet the standards 
    incorporated by reference or the specific requirements in this 
    subchapter, a request may be submitted under the equivalency provision 
    of Sec. 110.20-1. Requests under the equivalency provision will be 
    considered at the time a specific system design is submitted to the 
    Coast Guard for plan review and may be accepted as part of the system 
    plan approval.
        (6) Several comments indicated that, contrary to the Coast Guard's 
    intentions, the interim rule significantly increases the cost of doing 
    business internationally for U.S. shipyards. They expressed concern 
    that equipment protection, temperature, and operational characteristic 
    requirements have been increased beyond conventional practice. Due to 
    this perceived increase in requirements, the comments stated that 
    electrical equipment might require extensive additional testing to 
    demonstrate operability. These comments also noted that the 
    requirements for alarm, indicating and internal communications systems 
    have been greatly expanded. Finally, the comments pointed out that the 
    interim rule invokes requirements that did not previously exist and are 
    not found in trade literature. The comments' specific concerns are 
    addressed in the discussion of comments for the relative section.
        Generally, however, the perceived increases and changes to the 
    requirements in the final rule are actually a harmonization of the 
    Coast Guard's electrical engineering requirements with classification 
    society (ABS) and international (IEC) performance-based standards.
        (7) One comment expressed concern that the Coast Guard is heavily 
    reliant on ABS Rules when the ABS Rules may not be aligned with the 
    requirements of the International Association of Classification 
    Societies (IACS) Member Societies. Also, the comment expressed concern 
    that the regulations unfairly forced Member Societies to follow ABS 
    requirements for vessels operating in U.S. waters.
        The Coast Guard has traditionally incorporated by reference various 
    sections of ABS Rules into its electrical engineering regulations. This 
    rule expands on the use of ABS Rules as an option or alternative to 
    prescriptive requirements. However, the incorporation by reference of 
    specific ABS rules does not preclude the use of other rules approved 
    for specific applications under the equivalency provisions in 
    Sec. 110.20-1.
        Additionally, port state control inspections are performed mainly 
    to determine compliance with SOLAS 74 and some related Coast Guard 
    regulations. The requirements of subchapter J and its referenced 
    material apply to Coast Guard-certificated, U.S.-flag vessels only and 
    are not generally applicable to foreign vessels, unless specified 
    elsewhere in Coast Guard regulations.
        (8) One comment recommended incorporating more performance-based 
    standards and more Coast Guard policies to reduce the number of 
    requests seeking equivalency determinations under these regulations. 
    The comment expressed belief that adherence to performance standards
    
    [[Page 23896]]
    
    will foster greater innovation and improved overall safety.
        Throughout the regulation, the Coast Guard has incorporated, 
    wherever possible, a significant number of additional industry 
    standards, both domestic and international. Time and resource 
    limitations prevent the inclusion of every applicable standard. The 
    allowance of equivalencies would permit the inclusion of appropriate 
    standards that the Coast Guard has yet to review. This practice does 
    foster innovation and is consistent with the Coast Guard's intention to 
    serve the needs of industry while maintaining a comparable level of 
    safety.
        (9) Several comments pointed out that, at the time of the 
    publication of the interim rule, which incorporated the 1995 ABS Rules 
    for Building and Classing Steel Vessels, ABS had already published the 
    1996 edition of these rules.
        The text of this final rule incorporates the ABS Rules for Building 
    and Classing Steel Vessels, 1996 edition. ABS updated section 4/5 of 
    the ABS Rules for Building and Classing Steel Vessels by incorporating 
    international requirements and, at the same time, reorganized the 
    section into a more user-friendly format by dividing it into parts and 
    renumbering the paragraphs.
    
    II. Comments to Specific Sections
    
        Section 110.01-3. (1) Now that the rule is finalized, the option of 
    complying with regulations in effect at the time the alterations or 
    modifications are made has been removed from paragraph (b). Compliance 
    with this regulation is now mandatory.
        (2) Paragraph (c) has been amended to better define the term 
    ``conversion.''
        Section 110.10-1. (1) One comment suggested incorporating by 
    reference IEEE Recommended Practice on Surge Voltages in Low-Voltage AC 
    Power Circuits (IEEE Std 62.41-1991); UL 1449, Standard for Transient 
    Voltage Surge Suppressors; and UL 1778, Standard for Uninterruptable 
    Power Supply Equipment.
        These standards apply to uninterruptable power supplies (UPS) which 
    are not presently addressed in these regulations. While the value of 
    these standards are realized and their use is not prohibited by these 
    regulations, the Coast Guard will not include specific provisions or 
    requirements on this subject in this rule without allowing an 
    opportunity for public comment.
        (2) One comment suggested that American Petroleum Institute (API) 
    Recommended Practices (RP) should not be incorporated into these 
    regulations because they set forth domestic practices for fixed 
    platform and shoreside facilities and do not reflect international 
    consensus for vessels. It was suggested to consider incorporation of 
    IEC 1892, which is presently under development at an international 
    level.
        The Coast Guard agrees and is awaiting the publication of the IEC 
    standard for review. The Coast Guard may consider IEC 1892 in a 
    subsequent rulemaking where the public will have an opportunity to 
    comment. Until its publication, subchapter I-A, subparts 111.105 and 
    111.107, of this chapter and Coast Guard policy provide guidance for 
    MODU's and other Outer Continental Shelf (OCS) vessels.
        Section 110.15-1. (1) One comment recommended that the definition 
    of ``independent laboratory'' be changed to clarify that the 
    certification may not be performed in the absence of listing.
        The intent of the definition is to ensure that testing must always 
    be performed but also recognizes that laboratories vary in the 
    terminology of promulgating successful results. Certain laboratories 
    ``list'' products; other laboratories ``certify'' that products meet 
    certain standards.
        (2) One comment suggested that the requirement for watertight 
    enclosures of National Electrical Manufacturers Association (NEMA) Type 
    6 or 6P is excessive and suggested that NEMA Type 4 or 4X most closely 
    matches the IEEE Std 45 definition of watertight and exceeds the 
    definition of waterproof.
        The Coast Guard agrees and the definitions of ``watertight'' and 
    ``waterproof'' have been revised in accordance with IEEE 100. Examples 
    of industry accepted minimum degrees of protection requirements are 
    included.
        (3) One comment stated that the increase in the degree of 
    protection requirements for ``dripproof'' to IEC ingress protection 
    (IP) 32 will cause manufacturers to redesign electrical installations 
    aboard vessels; and IEC IP 22 is acceptable as the current industry 
    standard. Additionally, the comment recommended reinstating NEMA 250 
    Type 12 in this category.
        The Coast Guard agrees with all the recommendations and the 
    definition of ``dripproof'' has been revised accordingly.
        Section 110.25-1. (1) One comment recommended adding wording to 
    paragraph (i)(6) to clarify that, when required by the standard, proof 
    of listing and certification must also be submitted. This change would 
    align the regulatory language with the note to the same section.
        Paragraph (i)(6) has been revised accordingly.
        (2) Several comments suggested that, in the note to paragraph (n), 
    items required to meet an industry standard should only be certified by 
    an independent laboratory approved by the Commandant, and not simply 
    self-certified by the manufacturer. One comment pointed out that 
    elimination of this requirement would result in inferior equipment 
    severely jeopardizing shipboard safety. The comment suggests that at a 
    bare minimum any manufacturer conducting self-certification should be 
    ISO 9001 registered, which requires third-party evaluation of the 
    manufacturer's quality program.
        Before the recent revisions of subchapter J, the regulation in this 
    area required proof of listing only for equipment required to meet UL 
    standards; manufacturer's self-certification was allowed for other 
    standards such as IEEE, NEMA, and ANSI. The interim rule modified this 
    requirement by consolidating UL into the latter group. The Coast Guard 
    may consider requiring manufacturers, who wish to self-certify, to be 
    ISO 9001-registered in a subsequent rulemaking where the public will 
    have an opportunity to comment.
        (3) One comment recommended removing from paragraph (c) Marine 
    Safety Center (MSC) review of components to expedite review and 
    eliminate redundant review by the MSC and the Officer in Charge, Marine 
    Inspection (OCMI). The comment states that the certificate of 
    inspection is a better measure of safety.
        The inspection for certification of a vessel cannot be conducted at 
    the component level for most systems. The Coast Guard has a long-
    standing policy to allow plan review by third parties, such as 
    professional engineers and ABS, with oversight functions distributed 
    between the MSC and OCMI. The Coast Guard continues to find component 
    verification by the MSC necessary for these essential systems.
        Section 111.01-1. One comment suggested adding wording to prohibit 
    the use of combustible materials in the construction of electrical 
    equipment, for example, enclosures and foundations.
        It is Coast Guard policy, which is congruent with SOLAS 74, 
    Regulations II-2/34 and 49, to avoid the unnecessary use of combustible 
    materials. Therefore, new paragraph (b) has been added to this section.
        Section 111.01-9. (1) Several comments noted that, in paragraphs 
    (a) and (c), IEC IP 32 is an unduly severe degree of protection instead 
    of a NEMA 250 Type 2 enclosure and that IEC IP 22
    
    [[Page 23897]]
    
    is acceptable as the current industry standard.
        The Coast Guard agrees and has revised paragraphs (a) and (c) 
    accordingly.
        (2) Several comments suggested that the Coast Guard incorporate by 
    reference table 4/5B.1 of the 1996 ABS Rules for Building and Classing 
    Steel Vessels as acceptable minimum degrees of protection.
        This table has been added to paragraph (b) and to the note to this 
    section.
        (3) Several comments pointed out that the degree of protection 
    requirements NEMA 250 Type 6 or 6P and IEC IP 67 are too severe to be 
    designated as ``watertight''.
        The Coast Guard agrees and has revised the requirement to be NEMA 
    250 Type 4 or 4X and IEC IP 56 in paragraph (b) of this section and 
    wherever the watertight requirement appears in part 113 of this 
    chapter.
        (4) One comment suggested that an addition be made to these 
    regulations to avoid the possibility that the National Electrical Code 
    (NEC) requirements for land-based equipment near seashores might exceed 
    requirements in this subchapter.
        This subchapter addresses Coast Guard certificated vessels. Land-
    based electrical installations fall under different standards and are 
    not subject to this subchapter. The Coast Guard is not responsible for 
    the development of NEC requirements.
        Section 111.01-15. (1) Several comments pointed out that, in 
    paragraph (c), circuit breakers be allowed to be rated at 40  deg.C 
    instead of 45  deg.C because this is in accordance with marine circuit 
    breakers covered in UL 489, supplement SA incorporated into 
    Sec. 111.54-1(b) of this chapter. This would not preclude the option of 
    using 50  deg.C Navy type circuit breakers.
        Paragraph (c) has been revised accordingly.
        (2) One comment suggested that requiring a 55  deg.C rating for all 
    control and instrumentation equipment will cause manufacturers to 
    recertify and redesign equipment.
        The increase to 55  deg.C rating for these critical circuit 
    elements is in harmony with ABS Rules for Building and Classing Steel 
    Vessels, table 4/11.1, IEC 68, and IEC 92-101, table 4. Therefore, the 
    requirement is retained.
        (3) One comment noted that an ambient temperature of 40  deg.C 
    differs with the generally accepted IACS and IEC temperature of 45 
    deg.C.
        The Coast Guard has accepted 40  deg.C electrical equipment with 
    specific exceptions in areas of special concern as noted in this 
    section.
        Section 111.01-17. One comment noted that the regulations establish 
    new requirements and vendor testing to demonstrate operability.
        These requirements conform to the international standard IEC 92-101 
    and 1996 ABS Rules for Building and Classing Steel Vessels, table 4/
    5.1.
        Section 111.01-19. (1) One comment suggested that if the Coast 
    Guard were to provide a performance-based inclination criteria, the 
    result would be the elimination of equivalency determinations 
    applicable to any single class of vessel.
        No performance criteria were submitted in response to the interim 
    rule; however, the Coast Guard may consider any performance criteria 
    submitted for incorporation into a subsequent rulemaking.
        (2) One comment recommended changing the wording to exclude certain 
    items, such as dishwashers, toasters, and coffee makers, that are not 
    necessary to the maneuvering and safety of the vessel.
        This section has been revised to apply these requirements to 
    critical equipment and systems.
        (3) One comment stated that the new requirements, which ensure that 
    all electrical equipment is operable under certain extreme conditions 
    of list, roll, and trim, will result in greater expense due to the 
    installation of new equipment requiring additional tests.
        Although this section has been revised to apply to critical 
    systems, the inclination requirements are consistent with IEC 92-101, 
    table 3.
        Section 111.05-7. (1) One comment noted that this section is 
    redundant to Sec. 111.60-5.
        This section is retained because of its specific reference to 
    armored cable and grounding.
        (2) One comment recommended removing the reference to IEC 92-3 
    because this standard does not address installation guidance for armor 
    and sheathing.
        The reference to IEC 92-3 is retained because several sections of 
    Part 3 of the IEC publication, such as clauses 10.18 and 11.14, provide 
    guidance for metallic armor and sheathing.
        Section 111.05-9. One comment recommended incorporating the 
    American Boat and Yacht Council (ABYC) Standard E4 on lightning 
    protection.
        The Coast Guard agrees that guidance is appropriate for lightning 
    protection. The Coast Guard is incorporating the international standard 
    IEC 92-401, Electrical Installations in Ships; Part 401: Installation 
    and test of completed installation, section 10, Lightning Conductors.
        Section 111.05-19. One comment recommended additions to the 
    regulation for permitting high-impedance grounding schemes on all 
    vessels with a distribution voltage greater than 1,000 volts a.c. as 
    this method becomes an important tool for circuit protection, fault 
    coordination, and the limitation of equipment damage.
        While the value of this practice is realized and its use is not 
    prohibited by these regulations, the Coast Guard will not include 
    specific provisions or requirements on this subject in a final rule 
    without allowing an opportunity for public comment. However, this final 
    rule references this grounding method in Secs. 111.05-19 and 111.05-27.
        Section 111.05-23. (1) One comment suggested allowing either the 
    ground detecting equipment or an alarm signal from the detecting 
    equipment to be installed at the distribution switchboard via a control 
    cable instead of bringing back a phase conductor to the main 
    distribution switchboard. Also, the comment points out that allowing 
    the detection equipment to remain near the transformer would also make 
    it available for local troubleshooting.
        While this is the intent of paragraph (d), a note has been added to 
    the paragraph for clarification.
        (2) One comment recommended that paragraph (d) should be revised to 
    include only isolation devices greater than 10 kVA.
        Paragraph (d) has been revised to specify ``feeder'' circuits, 
    regardless of the load.
        (3) One comment suggested that the increase in the required number 
    of ground detector lights will have a great impact on the cost and 
    space.
        The revisions to paragraph (d) discussed previously should address 
    the concern of this comment by reducing the number of circuits 
    monitored and method of monitoring.
        Section 111.05-27. One comment stated that the requirement to 
    momentarily remove the indicating device is overly prescriptive and 
    recommended a more performance-based requirement to permit new 
    technology.
        The section has been revised to clarify intent.
        Section 111.05-33. (1) Several comments suggested revising this 
    section to clarify safety grounds (bonding) versus system grounds so 
    the language is technically accurate.
        This section has been revised accordingly.
    
    [[Page 23898]]
    
        (2) Several comments noted that clarification is necessary in 
    paragraph (b) to exclude ``system'' ground conductors which are 
    required by Coast Guard policy to be equal in size to the current 
    carrying conductors.
        Paragraph (b) has been revised accordingly.
        (3) One comment recommended revising the requirement to allow cable 
    armor and Type MC cable sheath as a grounding conductor as long as the 
    cable is third-party tested and listed (with its terminators) as 
    approved for this application.
        Coast Guard historically has prohibited the use of marine shipboard 
    cable braided armor or metallic sheath as the grounding conductor. Type 
    MC cable installation is required to be in accordance with the NEC as 
    stated in Sec. 111.60-23 of this chapter.
        Section 111.10-1. One comment requested a definition for the term 
    ``auxiliary propulsion'' since certain types of thrusters are designed 
    for use as ``take-home'' propulsive devices and thrusters are 
    specifically excluded from paragraph (a).
        The term ``auxiliary propulsion'' is revised to read ``propulsion 
    auxiliary'' to clarify that the intended machinery includes items such 
    as fuel oil service pumps, lube oil service pumps, purifiers, engine 
    sea water and fresh water cooling pumps, and air ejection equipment. 
    Non-conventional systems must be reviewed on a case-by-case basis to 
    consider such a thruster or ``take-home'' motor in a systems 
    relationship with the power generating equipment capacity.
        Section 111.10-9. One comment stated that propulsion and vessel 
    control are the critical components of the specified loads. The comment 
    noted that absent these systems, and given the ability of many safety 
    systems to operate in the absence of distributed electric power, the 
    additional redundancy and expense of two independent transformers is 
    not justified.
        Most vessels rely on distributed electric power for system 
    operation. Plans for any non-conventional system which does not rely on 
    power from the transformers may be submitted for review in accordance 
    with Sec. 110.20-1.
        Section 111.12-1. (1) One comment suggested that the Coast Guard 
    accept other major classification societies besides ABS to eliminate 
    differential between domestic rules and international standards. 
    According to the comment, ABS Rules create a burden on equipment 
    manufacturers with additional ``type-testing.''
        The Coast Guard has traditionally incorporated by reference various 
    sections of ABS Rules into its electrical engineering regulations. This 
    rule expands on the use of ABS Rules as an option or alternative to 
    Coast Guard prescriptive requirements. However, the incorporation by 
    reference of specific ABS rules does not preclude the use of other 
    rules approved for specific applications under the equivalency 
    provisions in Sec. 110.20-1, whereby the Coast Guard can consider 
    alternative ``type-testing.''
        Since ABS is a member of IACS and has recently revised its 
    electrical section 4/5 (section 4/3 of the ABS Rules for Building and 
    Classing Mobile Offshore Drilling Units) to incorporate many IEC 
    practices, the Coast Guard considers prime movers meeting these 
    sections to be aligned with international standards.
        (2) One comment noted that neither Coast Guard regulations nor ABS 
    Rules provide for automatic shutdown of a diesel generator's prime 
    mover upon failure of that engine's pressure lubrication system.
        The requirement in paragraph (c) of this section is retained 
    because, in addition to being sound engineering practice, table 4/11.10 
    of the 1996 ABS Rules for Building and Classing Steel Vessels provides 
    for automatic shutdown of diesel, steam, and gas turbine prime movers 
    upon low lube oil inlet pressure to that engine as well as to the 
    bearings of the electrical generator.
        Section 111.12-11. One comment recommended adding a new item to 
    paragraph (c) which would require the circuit breaker for a generator 
    to open upon the shutting down of the prime mover. This is a safety 
    feature required by ABS Rules for Building and Classing Steel Vessels, 
    1996, section 4/5A5.3.1.
        The inclusion of a low-voltage trip element, activated upon the 
    shutting down of the prime mover, has always been a feature on 
    generator circuit breakers and in the provisions of ABS Rules; however, 
    this requirement has been absent from Coast Guard regulations.
        It is now added in new paragraph (c)(1).
        Section 111.15-2. (1) One comment noted that the requirements of 
    this section will cause the U.S. marine industry to use specialized, 
    more expensive batteries. Also, the addition of a special nameplate 
    will increase costs.
        The Coast Guard utilizes regulations, incorporating Classification 
    Society Rules and standards, to ensure that equipment aboard 
    certificated vessels is suitable for the environment and the purpose 
    for which it is installed. This is particularly applicable to equipment 
    used in cases of emergency. Labeling of the product by the manufacturer 
    to attest to certain conditions is a cost effective method of 
    presenting this information to shipowners, operators, crew, and 
    inspectors.
        (2) One comment recommended the use of a more performance-based 
    standard instead of the specific requirements in paragraph (a). 
    Performance standards would preclude the necessity for equivalency 
    determinations for column stabilized units, surface effects vessels, 
    etc.
        The requirement of 40 degrees of inclination is consistent with IEC 
    92-101 and 92-305. Although a parameter for use of accumulator 
    batteries in ships, a unit designed for the environmental conditions of 
    marine installation should include this feature. The use of an 
    accumulator battery that does not meet this parameter may be requested 
    under the equivalency provision of Sec. 110.20-1. Submissions under the 
    equivalency provision will be considered at the time a specific system 
    design is submitted to the Coast Guard for plan review and may be 
    accepted as part of the system plan approval.
        Section 111.15-3. One comment suggested the addition of a three 
    pole disconnect switch located in the battery compartment of large 
    battery installation with a nominal voltage of higher than 120 volts 
    for use during servicing.
        This comment applies mainly to a large amount of cells for use with 
    uninterruptable power supply units and may be considered for inclusion 
    into a subsequent rulemaking where the public will have an opportunity 
    to comment.
        Section 111.15-5. (1) One comment noted that, in paragraph (c), 
    batteries are allowed in confined spaces if the batteries are sealed. 
    The comment recommended that no batteries, sealed or otherwise, should 
    be situated in confined areas because these units are only ``sealed'' 
    if everything is normal and may vent as much as standard cells under 
    abnormal conditions.
        Paragraph (c) has been revised accordingly.
        (2) One comment suggested that, in paragraph (e), it is sufficient 
    for a battery to have indication of manufacturer and type number on the 
    battery with documentation available to support the ampacity, 
    construction, and specific gravity requirements.
        Battery documentation is usually obscure and unavailable for 
    service personnel and inspectors and labeling is considered necessary 
    for maintenance and inspection.
    
    [[Page 23899]]
    
        Section 111.15-20. One comment recommended that, if the Coast Guard 
    is going to specify ampacity considerations, then it should also 
    specify a voltage drop in the criteria for cable sizing.
        Paragraph (c) has been revised to include the words ``while 
    maintaining the proper voltage at the load end.''
        Section 111.15-30. One comment indicated that the purpose of this 
    section is unclear and appears to be directed at a unique situation.
        The purpose of this section is to ensure that, from a systems 
    engineering perspective, battery installations and their chargers are 
    compatible. It also cautions against the use of some portable battery 
    chargers which may impose an unintentional ground of the vessel's power 
    supply system. Section 111.15-30 is retained.
        Section 111.20-1. (1) One comment suggested revising the 
    requirement to allow only transformers rated at less than 500 VA to be 
    installed in an enclosure as an alternative to the winding being 
    inherently resistant to moisture, sea atmosphere, and oil vapor. It 
    reasons that the long term integrity of enclosures for larger, 
    permanently fixed transformers may not survive the life cycle of the 
    vessel.
        This section is retained because it offers alternatives for this 
    equipment. Should the enclosure choice be selected, design, plan 
    review, installation, and inspection must all show suitability for 
    environmental conditions and applicability to the system in which it is 
    used.
        (2) One comment recommended revising the provision to allow an 
    exception for inherently current limiting ferro-resonant transformers 
    which are incorporated in a device meeting UL 1778.
        The Coast Guard determined that this equipment is for specific use 
    and uninterruptable power supplies. As stated previously, 
    uninterruptable power supplies will be addressed in the next revision 
    of the electrical engineering regulations. Until that time, use of 
    uninterruptable power supply systems are not specifically prohibited by 
    these regulations, and their usage is subject to the normal plan review 
    and inspection process.
        Section 111.30-5. (1) One comment noted that IEC 92-302 and 92-503 
    do not define low and medium voltages but refer to voltage ranges. Only 
    IEEE defines the terms.
        Paragraph (a) has been revised accordingly.
        (2) One comment suggested moving paragraph (b) to Sec. 111.01-9, 
    Degrees of protection.
        Paragraph (b) specifically addresses dripping and falling 
    substances, whereas, Sec. 111.01-9 addresses the universal enclosure 
    requirements as outlined in the referenced standards.
        Sections 111.30-9, 111.30-11, and 111.30-13. One comment 
    recommended that the provisions of these sections be reinstated. The 
    comment suggests that these operational safety standards should be set 
    as clear Coast Guard standards. The comment expressed a concern that if 
    a crew member were to remove an insulated floor matting or grating for 
    cosmetic reasons, the potential threat to safety would not be in 
    violation to any clear cut Coast Guard requirement; only a violation to 
    an obscure reference in a secondary document which might not be aboard 
    the vessel.
        The features described in the previously removed Secs. 111.30-9 
    (doors and non-conducting handrails) and 111.30-13 (grounding of 
    switchboard instrumentation) are all construction features to be 
    installed by the manufacturer in accordance with applicable standards. 
    In reference to previously removed Sec. 111.30-11 (mats or gratings), 
    the Coast Guard agrees that this is an important operational safety 
    concern and that specific guidance is warranted. The reinstated 
    performance-based requirement reflects international standards.
        Section 111.30-19. (1) One comment suggested adding punctuation to 
    paragraph (b)(3) to clearly distinguish between switchboard wire and 
    instrumentation wire.
        Paragraph (b)(3) has been revised accordingly.
        (2) Several comments indicated that paragraph (b)(6) and 
    Sec. 111.60-11, paragraph (d) cross-reference each other for 
    switchboard wiring and leave the requirements for switchboard wiring 
    undefined.
        The requirements for switchboard wiring are found in paragraph (b) 
    and its referenced standard. The cross-reference to Sec. 111.60-11 was 
    unnecessary and has been removed.
        (3) One comment recommended changing the wire size in paragraph 
    (b)(3) to #18 AWG to align with Sec. 111.60-4.
        The #14 AWG wire size requirement in this section is specific to 
    switchboard wiring, whereas the #18 AWG allowance in Sec. 111.60-4 is 
    for general wiring such as lighting fixtures or other uses where 
    appropriate.
        Section 111.30-21. One comment recommended retaining this section 
    with modifications to allow devices which operate at elevated 
    temperatures, but are self-cooling and do not adversely affect 
    surrounding components.
        The Coast Guard determined that the requirements removed from the 
    regulations are sufficiently addressed in the relevant construction 
    standards.
        Section 111.30-24. One comment requested clarification on the word 
    ``floating.''
        As discussed in the preamble to the interim rule, on page 28264, a 
    comment to the NPRM requested that exclusion for a non-self propelled 
    MODU be expanded to include other OCS facilities. Since subchapter J is 
    not universally applicable to fixed platforms, the Coast Guard accepted 
    the comment's suggestion to specify ``floating'' units which are 
    subject to the provisions of this subchapter such as tension leg 
    platforms (TLP) and semi-submersible production platforms.
        Section 111.30-25. Two comments noted that this section, which was 
    not addressed in the NPRM or the interim rule, is highly prescriptive 
    and limits the use of newer technologies.
        The Coast Guard has determined that any new equipment resulting 
    from advances in technology that performs the same function as those 
    devices listed in Sec. 111.30-25 can be considered for approval under 
    Sec. 110.20-1. The list in Sec. 111.30-25 is retained because the Coast 
    Guard determined it to be representative of those functions necessary 
    for the safe operation of a vessel.
        Section 111.33-11. One comment recommended specifying that ``ABS 
    Rules'' refers to the ABS Rules for Building and Classing Steel 
    Vessels.
        The Coast Guard agrees and has changed the reference from ``ABS 
    Rules'' to ``ABS Rules for Building and Classing Steel Vessels.'' 
    Additionally, the reference to ``ABS MODU Rules'' has been changed to 
    ``ABS Rules for Building and Classing Mobile Offshore Drilling Units.''
        Section 111.35-1. One comment requested a revision to this section 
    that requires an alarm indicating the failure of system ventilation.
        The Coast Guard may consider adding a requirement for an alarm 
    indicating the failure of a ventilation system in a subsequent 
    rulemaking where the public will have an opportunity to comment.
        Section 111.40-1. One comment noted that the deletion of this 
    section would result in the installation of panelboards never intended 
    for the marine environment. The comment suggests incorporating IEEE Std 
    45 to provide guidance for the construction of panelboards.
    
    [[Page 23900]]
    
        The Coast Guard agrees and is adding the suggested reference 
    because of its wide acceptance in the marine field.
        Section 111.51-3. One comment pointed out that wording is missing 
    from this section which would ensure proper protective device 
    coordination in all cases and round out the coordination declaration 
    made in Sec. 111.51-1.
        The Coast Guard agrees and the section is revised accordingly by 
    the addition of new paragraph (a).
        Section 111.53. One comment suggested adding specific wording that 
    prohibits the use of any fuse holder constructed of porcelain or 
    ceramic materials or any fuse that is of the screw-in type.
        The Coast Guard is reviewing the safety implications of screw-in 
    type fuses and may consider prohibiting those fuses in a subsequent 
    rulemaking where the public will have an opportunity to comment.
        Section 111.54-1. One comment suggested referencing IEC 56 for 
    circuit breakers above 1000 volts in place of the reference in 
    paragraph (c)(3)(ii) to IEC 947-2 for medium voltage circuit breakers.
        The Coast Guard agrees that the appropriate standard for circuit 
    breakers above 1000 volts is IEC 56. Paragraph (c)(3)(ii) is revised 
    accordingly.
        Section111.60-1. (1) One comment noted that in paragraph (a) the 
    word ``cooper'' should be changed to the word ``copper.''
        Paragraph (a) has been revised accordingly.
        (2) Several comments requested reinstatement of MIL-C-915F cable 
    pointing out that this is a current Navy standard and another comment 
    suggested further the addition of ``amendment 2'' to the MIL 
    specification.
        The Naval Sea Systems Command (NAVSEA) electrical office has 
    informed the Coast Guard that MIL-C-915 cable is not being installed in 
    new construction or major modifications. Additionally, its supply of 
    MIL-C-915 cable has been cut-up and sold for scrap.
        (3) One comment suggested that marine shipboard cable listed by a 
    Nationally Recognized Testing Laboratory (NRTL) accepted by the 
    Commandant is acceptable for use.
        The term ``NRTL'' is most commonly used by Occupational Safety and 
    Health Administration (OSHA) for safety-type testing, whereas cable 
    testing includes physical testing as well as fire testing. The Coast 
    Guard maintains a list of independent testing laboratories accepted by 
    the Commandant for this purpose. Present Coast Guard policy is 
    consistent with the suggestion.
        (4) One comment suggested deleting the terms ``construction'' and 
    ``identification'' from paragraph (a) and recommended that all cable 
    must meet the performance requirements in IEEE Std 45.
        As stated in paragraph (d), all electrical cable must now meet the 
    performance requirements of section 18 of IEEE Std 45.
        (5) One comment recommended for inclusion in paragraph
        (f) Type TC and Type ITC cables for industrial applications.
        Section 111.107-1 contains the regulations for industrial systems 
    and cables. Special purpose or ship-specific equipment can be accepted 
    as equivalent under Sec. 110.20-1 during plan review.
        (6) One comment recommended that incorporating IEC 92-3, removing 
    the words ``and identification'' from paragraph (a), and removing the 
    words ``and marking'' from paragraph (d) would result in economical 
    cables for shipbuilders. If this is not an option, the comment suggests 
    that the Coast Guard accept the minimum markings instead of requiring 
    the more extensive markings of IEEE Std 45.
        The Coast Guard has determined that the minimum marking 
    requirements are those in IEEE Std 45. The IEEE Std 45 markings 
    constitute the five basic pieces of information necessary for minimum 
    identification.
        (7) One comment suggested deleting paragraph (d) because it 
    unnecessarily adds additional performance requirements to material and 
    finished products which have met its particular standard.
        Paragraph (d) is retained because it ensures IEEE Std 45 
    performance standards are met and guarantees that minimum safety 
    criteria are upheld.
        (8) One comment suggested an editorial change in paragraph (f) to 
    correctly reference the IADC standard as an application standard.
        Paragraph (f) has been revised accordingly.
        (9) One comment recommended that in paragraph (e) the regulation 
    should specify a standard for high-voltage cable that is acceptable to 
    the Coast Guard.
        Presently, IEEE Std 45 and IEC 92-3 as well as several MIL 
    specifications and UL 1072 form the acceptable standards. The Coast 
    Guard may consider IEC 92-354 and IEC 502 in a subsequent rulemaking 
    where the public will have an opportunity to comment.
        Section 111.60-2. (1) One comment suggested deleting the reference 
    to ANSI/UL 1581 test VW-1 because it does not guarantee a degree of 
    flame propagation resistance such as the other specifications mentioned 
    in this section. It recommended replacing it with an alternate test CSA 
    FT-4.
        The flammability tests in this section are retained. The Coast 
    Guard may consider test CSA FT-4 in a subsequent rulemaking where the 
    public will have an opportunity to comment.
        (2) One comment suggested that it is not necessary to physically 
    separate specialty cable from other cable in all installations.
        Paragraph (a) requires physical separation only if the flammability 
    tests in the introductory text of this section cannot be met.
        (3) One comment recommended paragraph (b) be applied only to cable 
    runs installed in enclosed locations.
        Cable that cannot meet minimum flammability requirements must 
    comply with both paragraphs (a) and (b) to reduce the risk of flame 
    spreading among cable runs and throughout the vessel.
        Section 111.60-3. Several comments suggested revising paragraph (d) 
    to encompass special applications referred to throughout section 19 of 
    IEEE Std 45 and not limiting the focus on the particular application in 
    19.6.5 of the standard.
        Paragraph (d) has been revised accordingly.
        Section 111.60-4. One comment noted that the listed metric 
    conversions of AWG sizes do not correspond to standard metric wire 
    sizes. The comment suggests listing standard metric wire sizes that are 
    acceptable in lieu of the AWG sizes.
        The metric sizes that accompany AWG numbers are provided as 
    approximate metric dimensions and are ``soft'' conversions from the AWG 
    circular mil equivalents. Actual metric nominal size is found to differ 
    between such standards as JIS and European. Also, other wire gauge 
    systems exist such as British Standard and Birmingham whose nominal 
    sizes and actual dimensions differ from AWG and metrics. Electrical 
    plans are reviewed and approved by the Coast Guard usually with an AWG 
    size listed and annotated with ``or equivalent.'' It is up to the 
    designer to choose a cable with conductors capable of equal or greater 
    ampacity which will pass final inspection upon installation.
        Sec. 111.60-11. (1) One comment suggested modifying the section 
    title to read ``Wire (other than ground conductors).''
        The Coast Guard determined that this change is unnecessary because 
    this
    
    [[Page 23901]]
    
    section is self-explanatory and grounding conductors are covered 
    elsewhere.
        (2) One comment recommended qualifying the word ``enclosure'' as 
    ``equipment enclosure.''
        The Coast Guard determined that the suggested clarification is 
    unnecessary because wire is allowed in junction boxes, controllers, and 
    switchboards as well as equipment enclosures, for example, lighting 
    fixtures and motors.
        (3) One comment suggested revising paragraph (c) to reference the 
    appropriate standards for wire relative to IEEE Std 45.
        Paragraph (c) has been revised accordingly.
        Sec. 111.60-17. (1) One comment suggested including specific 
    requirements for crimped ferrules or pin terminals to prevent loose 
    strands of wire causing shorts when used with compression type 
    terminals.
        The Coast Guard determined that this is an installation quality 
    control issue addressed under the general requirements in Sec. 111.10-1 
    for electrical installations.
        (2) Several comments recommended prohibiting twist-on type 
    connectors, recommended including a referenced standard or method of 
    securing them to prevent loosening, or recommended eliminating 
    paragraph (b).
        The Coast Guard determined that this, again, is an installation 
    quality control issue addressed under the general requirements in 
    Sec. 111.10-1 for electrical installations. Twist-on connectors must be 
    installed in accordance with this entire section; safety is maintained 
    with proper installation. Industry has requested, and Executive Order 
    12866 demands, that government agencies include more performance-based 
    requirements rather than prescriptive regulation. Section 111.60-17 is 
    an example of the inclusion of a performance-based standard and 
    presents an allowance for other methods or new technology which meet 
    the same criteria.
        Sec. 111.60-19. One comment recommended revising paragraph (a) to 
    allow temporary splices within an enclosure in hazardous locations for 
    repair operations necessitated by damaged cable, where replacement of 
    such damaged cable would shut down vessel operations. The spliced cable 
    run could then be replaced at a later date while the vessel is in a 
    shipyard.
        The Coast Guard takes into consideration the economic conditions 
    and mission of the vessels it regulates, but its primary concern is the 
    safety of these vessels and their crews.
        It is the responsibility of certain persons in charge of a vessel 
    to notify the Coast Guard in the event of a marine casualty, accident, 
    or serious marine incident. The cognizant OCMI will determine the 
    course of action to be taken, notwithstanding temporary repairs of an 
    emergency nature which might be deemed necessary by the master.
        Sec. 111.60-23. (1) Several comments applauded the proposal to 
    allow limited use of Type MC cable. One comment noted that Type MC 
    cable had been used in the marine environment for more than 20 years. 
    It states that Type MC cable meeting the standards as proposed provides 
    an acceptable alternative while maintaining safety.
        (2) One comment expressed concern that a disproportionate number of 
    comments support the prohibition or restriction of Type MC cable in 
    marine locations.
        The Coast Guard determines regulatory policy based on the substance 
    of comments, rather than the number of comments, on a subject.
        (3) Several comments recommended that instrument tray cable (ITC) 
    (300 volt insulation) with similar Type MC cable construction be 
    allowed where allowed by NEC standards.
        Article 90-2(b) of the NEC states that the code does not generally 
    cover installations on vessels. NEC standards do not apply to Coast 
    Guard certificated vessels, unless specifically incorporated by 
    reference in this subchapter.
        Alignment with NEC standards is not necessarily an objective of 
    this rulemaking. ITC cable has not been evaluated for use aboard 
    vessels.
        (4) One comment noted that Sec. 111.60-23(a) refers to ``vessels'' 
    whereas paragraphs (c)(2) and (g) refer to ``offshore floating drilling 
    and production facilities.''
        The term ``vessel'' is broadly defined in section 3 of title 1 of 
    the U.S. Code to include floating production units, mobile offshore 
    drilling units, and ships. Paragraphs (c)(2) and (g) apply only to 
    offshore floating, drilling and production facilities.
        (5) Several comments suggested that the word ``welded'' as used in 
    the term ``continuously welded corrugated metal-clad (CWCMC) cable'' be 
    removed throughout Sec. 111.60-23 to conform with commercial 
    terminology. This will provide a continuous impervious corrugated metal 
    sheath manufactured by either the extrusion or welded process.
        The term ``continuously welded corrugated metal-clad (CWCMC) 
    cable'' in paragraph (a) has been changed to ``continuous corrugated 
    metal-clad cable'' and paragraph b(1) and paragraph (h) have been 
    changed accordingly.
        (6) One comment questioned why only corrugated as opposed to non-
    corrugated Type MC cable is allowed.
        Non-corrugated Type MC cable does not have the flexibility 
    necessary for use on vessels or floating facilities. Corrugated cable 
    would be less susceptible to cracking under these conditions.
        (7) Several comments recommended that the requirement for the UBVZ 
    listing on Type MC cable be removed. One comment stated that the UBVZ 
    listing does not affect construction of the cable or its suitability 
    for use on vessels, but does affect cable pricing and availability.
        The Coast Guard agrees. The UBVZ listing has been removed from 
    paragraph (b). This removal is also consistent with the Coast Guard's 
    position that metal-clad cable is a code product and not a marine 
    shipboard cable.
        (8) One comment recommended that the term ``impervious'' in 
    reference to the sheath of the cable be changed to ``gas/vaportight'' 
    because ``gas/vaportight'' is an NEC term.
        The terms ``gas-tight'' and ``vapor-tight'' have been added for 
    clarity.
        (9) One comment suggested that the term ``close-fitting'' be 
    removed as undefined.
        The words ``close-fitting around the conductors and fillers'' have 
    been added for clarity.
        (10) One comment stated that paragraph (b) was unclear as to what 
    an independent laboratory was to certify or list.
        Paragraphs (b)(2) and (b)(3) have been combined to correct this 
    discrepancy.
        (11) Two comments recommended that the restrictions for
        Type MC cable in paragraph (c)(1) should be moved to Sec. 111.60-3 
    because they are applicable to all cables.
        Type MC cable must be treated separately because it is not suitable 
    for applications such as elevators. Marine shipboard cable, described 
    in Sec. 111.60-1, must be used for all the services in paragraph (c).
        (12) Two comments suggested that Type MC cable should be allowed in 
    drilling function areas as it is recognized by API RP 14F for use on 
    fixed production facilities.
        API RP 14F applies only to fixed facilities. This subchapter does 
    not apply to fixed facilities.
        (13) Several comments recommended removing paragraphs (c)(2) and 
    (g). They contend that these paragraphs are prescriptive and are 
    already covered
    
    [[Page 23902]]
    
    under the performance standard in paragraph (c)(1).
        Paragraphs (c)(1) and (c)(2) have been combined for clarity and 
    paragraph (g) is retained. The Coast Guard does not allow the use of 
    Type MC cable in areas that are inherently subject to high vibration or 
    the other conditions specified in paragraph (c).
        (14) Several comments suggested that installation of Type MC cable 
    not be limited to article 334 because other articles within the NEC are 
    also applicable.
        The other applicable articles are already referenced in article 
    334.
        (15) Two comments recommended the acceptance of table A6 of IEEE 
    Std 45 as well as the ampacity tables given in the NEC since both are 
    based on the same method of calculation.
        Type MC cable is a code product, to be installed in accordance with 
    article 334 of the NEC and, therefore, the NEC's ampacity tables are to 
    be used.
        (16) Several comments suggested that the metallic sheath of Type MC 
    cable be allowed for use as a grounding conductor.
        The Coast Guard determined that there is insufficient historical 
    data on the use of Type MC cable on vessels to allow the metallic 
    sheath to be used as a grounding conductor. Even on shipboard cable, 
    the Coast Guard has never allowed braided armor to be used as a 
    grounding conductor. The Coast Guard maintains this policy with Type MC 
    cable.
        (17) Many comments suggested removing the prohibition of the use of 
    Type MC cable as interconnection between drilling and production 
    modules.
        The Coast Guard has revised paragraph (g) to allow Type MC cable to 
    be used as interconnection between drilling and production modules on 
    the same platform. Type MC cable is still prohibited as interconnection 
    between temporary drilling packages and platform production modules.
        (18) The Coast Guard is aware of the recently published UL 2225, 
    Metal-Clad Cables and Cable-Sealing Fittings For Use in Hazardous 
    (Classified) Locations, and may consider it as a reference in paragraph 
    (h) in a subsequent rulemaking where the public will have an 
    opportunity to comment.
        (19) One comment recommended that paragraph (h) be revised to avoid 
    confusion between terminations and fittings for Type MC cable and those 
    for similar cable, such as TECK.
        Paragraph (h) has been revised to assure that fittings and 
    terminations used must be compatible with the particular Type MC cable 
    used.
        Section 111.70-1. One comment stated that it is unsafe to allow one 
    phase to remain connected in ungrounded three-phase alternating current 
    systems.
        Paragraph (b) of this section refers to the controller/motor 
    overload relay and not the main disconnect device to isolate the 
    controller/motor from the power source. Paragraph (a) includes a 
    reference to ABS Rules for Building and Classing Steel Vessels 
    addressing the main disconnect and its relationship to the motor-
    running protective devices. Additionally, language has been added to 
    paragraph (b) to clarify that the opening of two phases refers to the 
    controller/motor overload devices.
        Section 111.70-3. (1) One comment suggested a revision to paragraph 
    (d)(1), by replacing ``and'' with ``or'' to clarify that when both a 
    controller and motor control center exist the identification 
    information should only be required at one of the two.
        Motor control centers group individual controllers into a central 
    location instead of installing each controller locally near its motor. 
    Normally, the use of one precludes the use of the other for a 
    particular motor.
        (2) One comment suggested eliminating items (v) and (vii) in 
    paragraph (d)(1) and listing information sufficient to identify the 
    motor controlled, its load, voltage and phase.
        The requirements in paragraph (d)(1) are consistent with IEEE Std 
    45 and in keeping with standard engineering practice to provide 
    important information necessary for the safe operation of the 
    electrical system.
        Section 111.70-7. One comment recommended an editorial change in 
    paragraph (d)(2) concerning the requirements of the disconnect device.
        Paragraph (d)(2) has been revised accordingly.
        Section 111.75-5. One comment recommended that in paragraph (b) the 
    term ``lamp sizes'' be changed to ``fixture ratings'', and retain the 
    minimum 50 watt requirement for convenience receptacles or IEEE Std 45, 
    paragraph 21.6 be referenced.
        Paragraph (b) has been revised accordingly.
        Section 111.75-15. One comment indicated that the text of paragraph 
    (c) is vague, providing no firm guidance. The comment suggests 
    incorporating IES RP 12, Recommended Practice for Marine Lighting.
        The Coast Guard may consider IES RP 12 in a subsequent rulemaking 
    where the public will have an opportunity to comment.
        Section 111.75-17. (1) One comment suggested that the term ``range 
    light'' in paragraphs (b) and (c) either needs to be defined or 
    replaced with the term ``masthead light.''
        The Coast Guard agrees and is removing the term ``range light'' 
    which is now referred to in the Convention on International Regulations 
    for Preventing Collisions at Sea, 1972 (72 COLREGS) as ``a second 
    masthead light.''
        (2) One comment recommended the inclusion of specific photometric 
    requirements for battery powered navigation lights.
        The Navigation Safety Advisory Committee (NAVSAC) reviewed the 
    adequacy of lighting on barges, which is generally powered by battery, 
    and concluded that no lighting requirement changes were necessary.
        Section 111.75-20. (1) One comment recommended revising paragraph 
    (a) so that it is clear that the paragraph does not apply to lighting 
    fixtures in hazardous locations.
        The Coast Guard is revising paragraph (a) accordingly.
        (2) Two comments suggested replacing the term ``meet'' with the 
    term(s) ``listed/certified'' to provide a means of verifying compliance 
    with any industry standard and requiring lighting fixtures to be tested 
    by an independent third party.
        It is Coast Guard policy that when a referenced standard requires 
    testing then the procedure is part of the regulation. Since the Coast 
    Guard maintains a process of independent laboratory acceptance by the 
    Commandant for items such as fire detection systems, cable, and marine 
    lighting fixtures, it is also part of our policy that such testing be 
    certified at these laboratories. The Coast Guard may consider third 
    party testing in a subsequent rulemaking where the public will have an 
    opportunity to comment.
        Section 111.85-1. One comment recommended that each oil immersion 
    heater be tested by an independent third party testing institution.
        An added requirement for compliance with a specific standard and 
    subsequent testing by a third party cannot be placed in this final rule 
    without opportunity for public comment. Recognizing the safety 
    implications of the equipment, the Coast Guard may consider the 
    inclusion of applicable safety standards and testing arrangements for a 
    subsequent rulemaking where the public will have an opportunity to 
    comment. Presently, guidance is afforded to both manufacturer and user 
    in subpart 111.01 of this chapter which establishes general criteria 
    for all electrical equipment so that it is appropriate for the
    
    [[Page 23903]]
    
    environment and purpose for which it is installed.
        Section 111.87-3. One comment suggested that in paragraph (a) 
    deleting the word ``meet'' and substituting the words ``listed/
    certified.''
        It is Coast Guard policy that when a referenced standard requires 
    testing then the procedure is part of the regulation. Since the Coast 
    Guard maintains a process of independent laboratory acceptance by the 
    Commandant for items such as fire detection systems, cable, and marine 
    lighting fixtures, it is also part of our policy that such testing be 
    certified at these laboratories. The Coast Guard may consider third 
    party testing in a subsequent rulemaking where the public will have an 
    opportunity to comment.
        Section 111.105. Several comments indicated that the obsolete MI 
    Type cable, referenced in Sec. 111.105-17, paragraph (a), has been 
    eliminated by the proposed IEEE Std 45 and should also be removed from 
    these regulations. Additionally, with new technologies in cable jacket 
    chemistry, these comments suggested that the armor requirements for 
    hazardous location cables also be removed, as they have been for non-
    hazardous areas.
        The Coast Guard agrees and subpart 111.105 has been revised 
    accordingly.
        Section 111.105-3. Several comments recommended revising this 
    section as it allows unarmored cable in hazardous locations.
        As indicated above in the discussion of comments for subpart 
    111.105, the general requirement for armored cable in all hazardous 
    locations has been removed.
        Section 111.105-5. One comment supports the inclusion of API RP 505 
    as a criteria for system integrity, while another comment stated that 
    it would be imprudent to consider the adoption of any API RP's because 
    they are superseded by IEC documents addressing both MODU's and fixed 
    platforms in a single comprehensive document.
        The API RP 505 is in draft form and as such is unavailable to the 
    Coast Guard for review or to the public for purchase. When the document 
    is published, the Coast Guard may consider API RP 505 for a subsequent 
    rulemaking where the public will have an opportunity to comment.
        The IEC, in which the U.S. participates, is in the final draft 
    stages of IEC Publication 1892 (IEC 1892), ``Mobile and Fixed Offshore 
    Units--Electrical Installations.'' IEC 1892, part 3 addresses hazardous 
    locations. This document reflects international consensus and will be 
    considered for inclusion in these regulations in a subsequent 
    rulemaking.
        Section 111.105-11. (1) One comment pointed out that the two 
    standards referenced in paragraph (a) are not compatible because IEC 
    79-11 defines two types of IS systems (Ia and Ib), whereas UL 913 
    defines only one.
        The Coast Guard accepts the UL 913 definition or IEC 79-11 (Ia) 
    only. Paragraph (a) has been revised accordingly.
        (2) Several comments recommended removing the option for shielded 
    cable in paragraph (b)(1) because most shielding may be very thin and 
    not suitable for safely providing sufficient isolation from non-IS 
    circuits. Another comment recommended in paragraph (b)(1) removing the 
    option for metallic armored cable since armoring is for mechanical 
    protection and not to be substituted for an electromagnetic 
    interference (EMI) shield.
        The purpose of paragraph (b)(1) is to offer options to protect 
    intrinsically safe circuit cables from induced voltages generated by 
    magnetic fields of non-intrinsically safe circuit cables. The Coast 
    Guard agrees that an armored covering is not meant to function as an 
    EMI shield. However, properly installed and grounded braided armor does 
    afford some degree of protection depending on intercircuit parameters. 
    Additionally, if a shielded cable is installed for protection, it is 
    assumed that its dimensions have passed plan review and that it is 
    suitable for the service intended. Both options are retained.
        Section 111.105-17. (1) One comment suggested clarifying the first 
    sentence in paragraph (a) so that not all hazardous locations are 
    required to have through runs of cable.
        The intention of paragraph (a) is that all hazardous areas be 
    fitted with through runs of cable, therefore the requirement remains.
        (2) Several comments suggested that paragraph (a) be revised to 
    require that cable in all hazardous locations be armored.
        As indicated above in the discussion of comments for subpart 
    111.105, the general requirement for armored cable in all hazardous 
    locations has been removed but the installation of armored cable 
    remains as an option.
        Section 111.105-31. One comment suggested adding a new paragraph 
    (f)(5) harmonizing Coast Guard and ABS requirements for pump room 
    ventilation and monitoring.
        The Coast Guard recognizes the need for direction on this subject. 
    However, new material must be presented to the public for comment 
    before a final rule. The Coast Guard may consider these provisions for 
    a subsequent rulemaking where the public will have an opportunity to 
    comment.
        Section 111.107-1. One comment recommended removing the word 
    ``and'' in paragraph (c)(1)(i) and adding the word ``or'' since either 
    standard will provide a comparable level of safety.
        This section has been revised accordingly.
        Section 112.05-5. One comment recommended modifying paragraph (d) 
    to allow equipment that supports the emergency power source (e.g., fans 
    and CO2 bottles).
        Paragraph (d) has been revised accordingly.
        Section 112.50-1. (1) One comment suggested adding a new paragraph 
    (l) that requires the generator circuit breaker open upon the shutting 
    down of the prime mover as required in ABS Rules for Building and 
    Classing Steel Vessels section 4/5.119.1.
        A similar comment was directed towards Sec. 111.12-11, Generator 
    protection, of this chapter. The requirement established in 
    Sec. 111.12-11 is applicable to all generators. The equipment described 
    in Sec. 112.50-1 are special features for emergency generators only. 
    Therefore the restating of this requirement is unnecessary.
        (2) One comment indicated that in paragraph (d) the 45 second 
    response time is longer than the 30 second response of the standby ship 
    service generator required for unattended machinery plants in 46 CFR 
    62.50-30(k)(2).
        The 45 second requirement in this section is for emergency 
    generator sets and is aligned with SOLAS 74, Regulation II-1/42.3.1.2 
    requirements. The 30 second requirement in 46 CFR part 62 is for a 
    standby ship service generator in an unattended machinery space. If the 
    standby ship service generator does not come on line within its 
    allotted time, the emergency source would power its circuits shortly 
    thereafter.
        Section 112.50-7. One comment indicated that paragraph (c)(3) 
    appears to have been deleted.
        The five asterisks after paragraph (c)(2) indicates that the 
    remainder of this section is retained. However, paragraph (d) is 
    removed by the amendatory language of item 169 in the interim rule.
        Part 113. One comment pointed out that the title of several 
    sections of this part use the words ``alarm system'' as a general term 
    for the ``general emergency alarms and fire alarms.'' It suggested not 
    using this terminology because it
    
    [[Page 23904]]
    
    typically describes ``machinery alarm systems.''
        In this part, the terminology is used with consideration of the 
    context of each subpart. Wherever in this part the regulations 
    reference the general emergency alarm system, the words ``general 
    emergency alarm system'' are used. The more generic term of ``alarm 
    system'' is used in reference to machinery alarm systems and other 
    specialized alarms such as engineers' assistance needed, steering 
    failure, and refrigerated spaces where appropriate.
        Section 113.05-7. (1) One comment noted that in paragraph (b) the 
    reference to IEC 553 is a misprint and should read IEC 533 (entitled 
    Electromagnetic Compatibility of Electrical and Electronic 
    Installations in Ships) as stated in Sec. 110.10-1, Incorporation by 
    reference.
        Paragraph (b) has been revised accordingly.
        (2) One comment stated that the environmental test requirements of 
    this section are burdensome if applied to each new piece of equipment 
    due to advances in technology and the continual development of new 
    components. The comment suggested creating a self-certification 
    requirement similar to 46 CFR 62.20-5, Self-certification.
        The Coast Guard does not deem self-certification as sufficient for 
    this equipment. Testing of original and redesigned equipment required 
    by subchapter Q to be Coast Guard ``approved'' is performed by 
    independent laboratories accepted by the Commandant. The testing 
    protocols and their results are strictly reviewed by the Coast Guard or 
    designated third parties before an approval certificate is issued. 
    Alarms that are allowed in 46 CFR part 62 to be self-certified must be 
    designed to meet the environmental standards of 46 CFR 62.25-30, 
    Environmental design standards, which reference ABS Rules for Building 
    and Classing Steel Vessels. Subchapter J also references ABS (ABS Rules 
    for Building and Classing Steel Vessels, table 4/11.1) for 
    environmental testing requirements.
        Section 113.10-7. One comment suggested that the requirement for 
    connection boxes to meet IEC IP 67 is unnecessarily severe.
        In all subparts where the interim rule required connection boxes to 
    be NEMA 250 Type 6 or 6P or IEC IP 67, the requirement has changed to 
    NEMA 250 Type 4 or 4X or IEC IP 56 to align the requirement with the 
    definition of ``watertight.''
        Section 113.25-10. One comment suggested that red flashing lights 
    be used only in conjunction with the general emergency alarm signal and 
    for no other purpose. This is preferable to the IMO Code on Alarms and 
    Indicators, which allows the color red to also be used when indicating 
    the release of fire-extinguishing medium. A standardized color would 
    allow quick identification and response by personnel.
        While the value of this practice is realized, the Coast Guard will 
    not include specific provisions or requirements on this subject in this 
    rule without allowing an opportunity for public comment. The term 
    ``flashing red lights'' has been changed to include rotating beacons as 
    well.
        Section 113.25-11. One comment suggested revising the introductory 
    sentence in Sec. 113.25-11 to read as follows, ``Each contact maker, 
    where installed, must--''
        The Coast Guard determined that the requirements listed in this 
    section apply to all contact makers, conventional or electronic type 
    integrated in the public address system, and the addition of the words 
    ``where installed'' does not add to the clarity of the sentence.
        Section 113.25-12. One comment recommended in paragraph (a) the use 
    of air operated alarm signals which may be actuated by a solenoid valve 
    located outside the hazardous area.
        This section does not preclude air operated alarm signals or other 
    types compatible with the environment in which they are used. Any new 
    or non-conventional alarm signal will be considered in the plan review 
    process.
        Section 113.30-3. One comment requested clarification of the phrase 
    ``must be independent of the ship's electrical system.'' The ship's 
    electrical system may be interpreted to mean the ship's AC electrical 
    system or the ship's DC system with a battery power source.
        The power for the emergency means of communication required by this 
    subpart must not be reliant upon the vessel's normal source or 
    emergency source of AC or DC power. Acceptable methods of power include 
    sound-powered phone, telephone systems which are powered by hand 
    cranked generators which charge capacitor circuits, and individually 
    battery powered devices.
        Section 113.30-5. (1) One comment suggested that in paragraph (a) a 
    cross-reference to 46 CFR 62.50-20(f)(2) be added.
        The cross-reference to 46 CFR 62.50-20 has been added.
        (2) One comment recommended editorial revision to paragraph (h)(1) 
    for clarity.
        Paragraph (h)(1) has been revised accordingly.
        Section 113.30-25. (1) One comment indicated in paragraph (i) that 
    cables for safety related circuits should only be permitted to be 
    routed through high fire risk areas if it is technically impractical to 
    route them otherwise or if they serve circuits within the high risk 
    area. In either case, cables should be of the fire resistant type. The 
    comment stated that decisions in these areas should not be affected by 
    commercial considerations.
        The Coast Guard develops its regulations with the primary 
    consideration being safety. Any commercial consideration would be 
    secondary and related to cost savings to the industry through 
    harmonizing with domestic and international industry standards 
    resulting in additional options.
        Section 111.60-1 requires that accepted marine shipboard cable must 
    meet the respective flammability tests contained in the referenced or 
    companion standards. These tests are a validation that the cable is 
    ``flame retardant''; i.e., that the flame is not propagated. IEC 331, 
    however, measures the ``fire-resisting'' characteristics as noted in 
    the scope ``as one which will continue to function normally during and 
    after a prolonged fire.''
        As published in the interim rule, paragraph (i) states that cable 
    runs through high fire risk areas, which includes servicing equipment 
    within these areas, must meet IEC 331. It is the intent that such 
    cables not only prevent the proliferation of flame but also maintain 
    service to the equipment as well.
        (2) One comment suggested modifying the last line of paragraph (e) 
    to read ``an emergency power source'' instead of ``the vessel's 
    electric system.''
        The paragraph has been revised to clarify which vessel's electric 
    source is intended.
        Section 113.43-3. The reference to Secs. 58.25-45 and 111.93-9 is 
    out-of-date and has been corrected.
        Section 113.50-15. One comment noted that, as written, this section 
    appears to require explosionproof speakers in hazardous locations, for 
    example, a cargo pump room on a tanker. The comment requests review of 
    this requirement to determine whether it is excessive.
        All systems and enclosures for hazardous locations must be 
    certified for the particular Class and Division (Zone) in which they 
    are installed. In the example given, if the speaker system were to be 
    found intrinsically safe during plan review, then explosionproof 
    speakers would not be required. Alternatively, if a study did not prove 
    that the speakers were necessary in that
    
    [[Page 23905]]
    
    location, they would be disallowed under Sec. 111.105-31(f) or, if 
    proven necessary, they must be explosionproof.
        Section 113.50-20. One comment suggested adding additional 
    requirements applicable to public rooms, alleyways, and stairways to 
    align the regulations with the IMO Code of Alarms and Indicators.
        The Coast Guard may consider additional requirements to align 
    Sec. 113.50-20 with the IMO Code on Alarms and Indicators in a 
    subsequent rulemaking where the public will have an opportunity to 
    comment.
        Section 113.70. One comment recommended adding a new subpart that 
    addresses the installation and operation of gas detection systems. The 
    comment suggests these systems meet the general requirements of the 
    International Society for Measurement and Control (ISA) SP12.13 parts I 
    and II.
        The Coast Guard may consider additional requirements for gas 
    detection systems in a subsequent rulemaking where the public will have 
    an opportunity to comment.
        Section 161.002-1. Components for automatic fire detection systems, 
    EN54 parts 1 through 11, published by the European Committee for 
    Standardization (CEN) remain absent from this section because several 
    of the documents obtained by the Coast Guard were in draft form. The 
    Coast Guard may consider the finalized documents for a subsequent 
    rulemaking where the public will have an opportunity to comment.
    
    Incorporation by Reference
    
        The Director of the Federal Register has approved the material in 
    Secs. 110.10-1 and 161.002-1 for incorporation by reference under 5 
    U.S.C. 552 and 1 CFR part 51. Copies of the material are available from 
    the source listed in those sections.
    
    Regulatory Evaluation
    
        This rule is not a significant regulatory action under section 3(f) 
    of Executive Order 12866 and does not require an assessment of 
    potential costs and benefits under section 6(a)(3) of that Order. It 
    has not been reviewed by the Office of Management and Budget under that 
    Order. It is not significant under the regulatory policies and 
    procedures of the Department of Transportation (DOT) (44 FR 11040; 
    February 26, 1979). A Regulatory Evaluation under paragraph 10e of the 
    regulatory policies and procedures of DOT is available in the docket 
    for inspection or copying where indicated under ADDRESSES. A summary of 
    the Evaluation follows:
        Most of the changes to the regulations are either editorial or 
    update technical specifications to reflect the latest practices. 
    Although some of these changes will cause minor cost increases for 
    shipbuilders, others will result in substantial savings. The cost 
    increases resulting from these rules will be more than offset by the 
    cost savings, due to relaxations in the rules. The Coast Guard 
    estimates that the cost of complying with the rule over the next 10 
    years will total $33,753,392 (in present value); but, this cost will be 
    more than offset by the estimated net benefits of $73,538,213. This is 
    a cost-benefit ratio of $1.00 of costs to $2.18 of benefits.
        Many of the changes causing cost increases are already current 
    marine industry practices, such as an increase in the protection of 
    cable from bilge water.
        There are several intangible benefits. Due to the increased use of 
    national and international standards, certain items will now be more 
    readily available ``off the shelf'' for marine use. A significant 
    economic savings will result from the ability of equipment 
    manufacturers, in many cases, to meet the new performance 
    specifications instead of the old, prescriptive design standards. Also, 
    the cost of submitting detailed plans and specifications to the Coast 
    Guard for approval of certain equipment, such as sound powered 
    telephones, emergency loudspeaker systems, and navigation lights, will 
    be eliminated.
        No comments were received to the Regulatory Evaluation or its 
    summary in the preamble to the interim rule.
    
    Small Entities
    
        Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the 
    Coast Guard considered whether this final rule will have a significant 
    economic impact on a substantial number of small entities. ``Small 
    entities'' include small businesses, not-for-profit organizations that 
    are independently owned and operated and are not dominant in their 
    fields, and governmental jurisdictions with populations of less than 
    50,000.
        This rule will affect entities that come under Standard Industrial 
    Code (SIC) categories of 4412 through 4489 (Water Transportation) and 
    1311 and 1381 (Oil and Gas Extraction), both groups of which are 
    considered small entities if they have 500 or less employees, and under 
    SIC category 3731 (Shipbuilding and Repair), which are considered small 
    entities if they have 1,000 or less employees.
        The Coast Guard has taken measures to accommodate the interests of 
    small entities during the development of this rule. The rule is limited 
    to vessels that are constructed or undergo major modifications after 
    September 30, 1996, thereby exempting the existing fleet from having to 
    conform to these requirements. Furthermore, it is limited to Coast 
    Guard-inspected commercial vessels, such as oil and chemical tankers, 
    container ships, large passenger vessels, mobile offshore drilling 
    units, research vessels, and school ships, which tend to be larger 
    vessels. It does not apply to uninspected passenger vessels, commercial 
    fishing vessels, or the overwhelming majority of inspected, small-
    passenger vessels.
        To reduce the burden on small entities, this rule purges obsolete 
    and out-of-date regulations and eliminates requirements that create an 
    unwarranted differential between Coast Guard's regulations and industry 
    standards. It enhances the flexibility of vessel owners, operators, 
    manufacturers, and shipbuilders by incorporating, wherever possible, 
    more options for compliance or by replacing prescriptive requirements 
    with performance standards.
        This rule reduces costs by increasing choices available during the 
    new construction or major modification of a vessel. As discussed under 
    the Regulatory Evaluation section in this preamble, this rule will 
    reduce costs of shipbuilding for all entities, whether large or small. 
    The Coast Guard estimates that the cost of complying with the rule over 
    the next 10 years will total $33,753,392 (in present value); but, this 
    cost will be more than offset by the estimated net benefits of 
    $73,538,213. This is a cost-benefit ratio of $1.00 of costs to $2.18 of 
    benefits.
        Therefore, the Coast Guard certifies under section 605(b) of the 
    Regulatory Flexibility Act (5 U.S.C. 601 et seq.) that this final rule 
    will not have a significant economic impact on a substantial number of 
    small entities.
    
    Assistance for Small Entities
    
        In accordance with section 213(a) of the Small Business Regulatory 
    Enforcement Fairness Act of 1996 (Pub. L. 104-121), the Coast Guard 
    offers to assist small entities in understanding this rule so that they 
    can better evaluate its effects on them. If your small business or 
    organization is affected by this rule and you have questions concerning 
    its provisions or options for compliance, please contact Ms. Laura 
    Hamman, Office of Design and Engineering Standards, 202-267-2206.
    
    [[Page 23906]]
    
    Collection of Information
    
        This final rule provides for a collection of information under the 
    Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
    
        I. The following particulars apply to subpart 110.25:
        DOT No.: 2115.
        OMB Control No.: 2115-0115.
        Administration: U.S. Coast Guard.
        Title: Electrical Engineering Requirements for Merchant Vessels.
        Need for information: Subpart 110.25 requires industry to complete 
    electrical engineering plans to meet performance requirements on newly 
    built vessels and modifications of current vessels.
    
    Proposed Use of Information
    
        This information is necessary to determine compliance with the 
    electrical regulations before vessel construction or modification 
    begins.
        Frequency of Response: The information must be submitted when a 
    vessel is built or modified.
        Burden Estimate: 478 hours.
        Respondents: 175 owners or operators.
        Average Burden Hours per Respondent: 1 hour per submission.
    
        II. The following particulars apply to subpart 161.002:
        DOT No.: 2115.
        OMB Control No.: 2115-0121.
        Administration: U.S. Coast Guard.
        Title: Electrical Engineering Requirements for Merchant Vessels.
        Need for Information: Subpart 161.002 concerns application for type 
    approval of fire protection systems.
        Proposed use of Information: This information is necessary to 
    ensure compliance with the electrical regulations.
        Frequency of Response: A response is due each time initial approval 
    is sought and each time a revision is requested.
        Burden Estimate: 60 hours.
        Respondents: 6 manufacturers.
        Average Burden Hours per Respondent: 10 hours per respondent.
        As required by 5 U.S.C. 3507(d), the Coast Guard submitted a copy 
    of this rule to the Office of Management and Budget (OMB) for its 
    review of the collection of information. OMB has approved the 
    collection. The subpart numbers are 110.25 of subchapter J and 161.002 
    of subchapter Q. The corresponding OMB approval numbers are OMB Control 
    Number 2115-0115 for subpart 110.25, which expires on August 3, 1999, 
    and OMB Control Number 2115-0121 for subpart 161.002, which expires 
    September 30, 1999.
        Persons are not required to respond to a collection of information 
    unless it displays a currently valid OMB control number.
    
    Federalism
    
        The Coast Guard has analyzed this rule under the principles and 
    criteria contained in Executive Order 12612 and has determined that 
    this rule does not have sufficient federalism implications to warrant 
    the preparation of a Federalism Assessment.
    
    Environment
    
        The Coast Guard considered the environmental impact of this rule 
    and concluded that, under paragraph 2.B.2.e(34)(d) and (e) of 
    Commandant Instruction M16475.1B, this rule is categorically excluded 
    from further environmental documentation. This rule concerns only 
    system arrangement and equipment approval. The approved system 
    arrangement and equipment required by this rule should contribute to 
    the enhancement of vessel safety and, thereby, help to minimize impacts 
    on the marine environment. A ``Categorical Exclusion Determination'' is 
    available in the docket for inspection or copying where indicated under 
    ADDRESSES.

    leakage into the enclosure is allowed if it does not interfere with the 
    operation of the equipment enclosed. In the case of a generator or 
    motor enclosure, waterproof means watertight; except that, leakage 
    around the shaft may occur if the leakage is prevented from entering 
    the oil reservoir and the enclosure provides for automatic drainage.
        Watertight means enclosed so that equipment meets at least a NEMA 
    250 Type 4 or 4X or an IEC IP 56 rating.

    * * * * *
        (b) Combustible material should be avoided in the construction of 
    electrical equipment.
        8. In Sec. 111.01-9, in paragraphs (a) and (c), remove ``32'' and 
    add, in its place, ``22'' and revise paragraph (b) and the note to this 
    section to read as follows:
    
    
    Sec. 111.01-9  Degrees of protection.
    
    * * * * *
        (b) Electrical equipment in locations requiring exceptional degrees 
    of protection as defined in Sec. 110.15-1 of this chapter must be 
    enclosed to meet at least the minimum degrees of protection in ABS 
    Rules for Building and Classing Steel Vessels, table 4/5B.1, or 
    appropriate NEMA 250 Type for the service intended. Each enclosure must 
    be designed in such a way that the total rated temperature of the 
    equipment inside the enclosure is not exceeded.
    * * * * *
        Note to Sec. 111.01-9: The degrees of protection specified in 
    this section are described in NEMA Standards Publication No. 250 and 
    IEC IP Code 529 and designated in ABS Rules for Building and 
    Classing Steel Vessels, table 4/5B.1.
    
        9. Revise Sec. 111.01-15(c) to read as follows:
    
    
    Sec. 111.01-15  Temperature ratings.
    
    * * * * *
        (c) A 45 deg.C ambient temperature is assumed for cable and all 
    other non-rotating electrical equipment in boiler rooms, in engine 
    rooms, in auxiliary machinery rooms, and on weather decks. For 
    installations using UL 489 SA marine type circuit breakers the ambient
