ACTION: Notice of proposed rulemaking. ----------------------------------------------------------------------- SUMMARY: As part of the President's Regulatory Reinvention Initiative, the Coast Guard proposes to amend its electrical engineering regulations to reduce the regulatory burden on the marine industry, purge obsolete and out-of-date regulations, and eliminate requirements that create an unwarranted differential between domestic rules and international standards. This proposed rulemaking would harmonize, where possible, the electrical engineering regulations with recent amendments to the International Convention for the Safety of Life at Sea, 1974, as amended. Additionally, this proposed rulemaking would dramatically revise certain prescriptive electrical equipment design, specification, and approval requirements and replace them with performance-based requirements that incorporate international standrds. DATES: Comments must be received on or before March 18, 1996. ts to the International Convention for the Safety of Life at Sea, 1974, as amended.

Background and Purpose uest a public hearing by writing to the Marine Safety Council at the address under ADDRESSES. The request should include the reasons why a hearing would be beneficial. If it determines that the opportunity for oral presentations will aid this rulemaking, the Coast Guard will hold a public hearing at a time and place announced by a later notice in the Federal Register. Background and Purpose On March 30, 1995, the Coast Guard published a notice of a public meeting in the Federal Register (60 FR 16423) and solicited written comments on the President's recently announced Regulatory Reinvention Initiative as well as the Coast Guard's regulatory development process. The meeting was held on April 20, 1995, with a written comment period extended from May 1 to December 8, 1995. On May 31, 1995, the Coast Guard published a notice in the Federal Register (60 FR 28376) that stated that the Coast Guard has established a goal of eliminating any regulatory differential between requirements that apply to U.S. vessels in international trade and those that apply to similar vessels in international trade that fly the flag of responsible foreign nations. To the maximum extent possible, requirements that create an unwarranted differential between U.S. and internationally recognized standards will be eliminated. This revision of the electrical engineering regulations is, in part, part of this project. The Coast Guard's electrical safety regulations are based on statutory authority provided in 46 U.S. Code (U.S.C.) 3306 and 3703. The existing regulations for inspected vessels are contained in chapter I, subchapter J, of title 46 of the Code of Federal Regulations (46 CFR chapter I, subchapter J). This proposal is mainly concerned with changes to this subchapter but associated changes in subchapters I-A and Q also are being proposed. All cites in this proposal, unless otherwise indicated, are to title 46 CFR and 3703. The existing regulations for inspected vessels are contained in chapter I, subchapter J, of title 46 of the Code of Federal Regulations (46 CFR chapter I, subchapter J). This proposal is mainly concerned with changes to this subchapter but associated changes in subchapters I-A and Q also are being proposed. All cites in this proposal, unless otherwise indicated, are to title 46 CFR. This project proposes to revise technical areas of subchapter J to address comments received from Coast Guard field and inspection offices and the marine industry; to clarify requirements where confusion has been shown to exist; to delete or significantly modify obsolete requirements; to reflect experiences with vessel reflaggings; and to more closely parallel international standards. The revision also proposes to incorporate the latest International Convention for the Safety of Life at Sea, 1974 (SOLAS 74) amendments (up to and including 1992), elements of the Coast Guard Regulatory Reform (CGRR) initiative, and industry standards. The increased frequency of overseas construction of U.S. flag vessels has created a need for the Coast Guard to recognize equipment designed and installed in accordance with international standards. The implementation of SOLAS 74 by the international maritime community has promulgated requirements which closely parallel existing Coast Guard regulations. Subchapter J will be revised to facilitate U.S. acceptance of electrical equipment constructed in accordance with other international standards. To eliminate needless regulatory burden, the Coast Guard is proposing to delete and extensively revise obsolete or confusing regulations. For example, the entries for Engine Order Telegraphs are proposed to be consolidated and updated. Additionally, the necessary degree of safety and reliability for sound powered telephones can be maintained with minor additions to subchapter J al standards. To eliminate needless regulatory burden, the Coast Guard is proposing to delete and extensively revise obsolete or confusing regulations. For example, the entries for Engine Order Telegraphs are proposed to be consolidated and updated. Additionally, the necessary degree of safety and reliability for sound powered telephones can be maintained with minor additions to subchapter J. This proposal would encompass the changes which would make type approval by the Government unnecessary. Therefore, in conjunction with these proposed changes, the Coast Guard would remove the approval requirement for sound powered telephone equipment (now in subchapter Q) and adopt minimum performance requirements in subchapter J. Similar treatment is being given Fire Protective Systems. A wide variety of national and international standards covering different types of equipment are also proposed for incorporation by reference. Also under the proposal, the equipment manufacturer would be afforded a choice of Independent Laboratories versus the old single-point of testing. Modification of current requirements is allowed under existing U.S. statutes, as 46 U.S.C. 3306 and 3703 provide broad authority to the Secretary to prescribe safety regulations. Presently in the regulations, a Fire Protection Equipment manufacturer is required to provide a sample of its system, built only to the rigid specifications in part 161, subpart 161.002, to the National Bureau of Standards for testing. The Coast Guard would allow equipment to be constructed to several domestic and an internationally recognized standards. Also, the Coast Guard continues to process applications from a variety of third party testing institutions and Commandant (G-MMS) maintains a list at Coast Guard headquarters of Independent Laboratories recognized by the Commandant. The use of large industrial systems independent of a traditional ship's service and propulsion functions are becoming increasingly popular recognized standards. Also, the Coast Guard continues to process applications from a variety of third party testing institutions and Commandant (G-MMS) maintains a list at Coast Guard headquarters of Independent Laboratories recognized by the Commandant. The use of large industrial systems independent of a traditional ship's service and propulsion functions are becoming increasingly popular. These types of systems provide power to systems that are vital to a vessel's mission but not necessarily to its safety. Industrial systems would include drilling, manufacturing and scientific research. Due to the industrial nature of these systems, it is not necessary for them to meet the requirements in subchapter J which are intended to provide for reliable ship's service and electrical propulsion systems. New requirements, therefore, are being proposed which would permit the use of standard industrial equipment without requiring them to meet many of the requirements of subchapter J. Electrical installations in hazardous locations will continue to meet explosion-proof/ intrinsically-safe requirements. This action serves the needs of industry while ensuring a comparable level of safety. On November 1, 1974, the Assembly of the International Maritime Organization (IMO) adopted the International Convention for the Safety of Life at Sea, 1974 (SOLAS 74). To date, IMO has adopted seven sets of amendments to the convention pursuant to Article VIII of SOLAS 74. The United States has played an instrumental role in the development of the Convention and its amendments. As a signatory nation to this international treaty, the United States has embraced these amendments and periodically upgrades existing regulations, as necessary, to bring it into alignment with the SOLAS 74 requirements. The Coast Guard's electrical engineering regulations were last updated in 1982. In that rulemaking, the Coast Guard reorganized its regulations and incorporated the first set of amendments to SOLAS 74 is international treaty, the United States has embraced these amendments and periodically upgrades existing regulations, as necessary, to bring it into alignment with the SOLAS 74 requirements. The Coast Guard's electrical engineering regulations were last updated in 1982. In that rulemaking, the Coast Guard reorganized its regulations and incorporated the first set of amendments to SOLAS 74. This rulemaking proposes incorporating the second through seventh sets of amendments to SOLAS 74 (those of 1983, 1988, 1989, 1990, 1991, and 1992.) In doing so, the Coast Guard inspected vessels' electrical safety regulations would be aligned with the international standards for safety which are accepted for merchant ships around the world. Discussion of Proposed Rules The proposed revisions to 46 CFR chapter I, subchapter J, would clarify and condense, in technically correct language, the Electrical Engineering Regulations applicable to U.S. Coast Guard certificated vessels. The objective of these revisions is to further reduce the regulatory burden on the industry, eliminate misinterpretation of the regulations by all affected parties, and bring the regulations in line with the state of the art technology in the industry as well as with standards accepted by the international maritime community. The major changes to subchapter J are discussed below. Other changes which are editorial and do not affect the technical content of this subchapter are not addressed. The editorial corrections are to help the reader understand the intent of the requirements. As part of the associated changes, the Coast Guard is also proposing to revise 46 CFR 108.170, Definitions, and Sec. 108.181, Ventilation for enclosed spaces, to refer to the appropriate sections of subchapter J re editorial and do not affect the technical content of this subchapter are not addressed. The editorial corrections are to help the reader understand the intent of the requirements. As part of the associated changes, the Coast Guard is also proposing to revise 46 CFR 108.170, Definitions, and Sec. 108.181, Ventilation for enclosed spaces, to refer to the appropriate sections of subchapter J. In addition to updating subchapter J to reflect the most recent amendments to SOLAS 74, the Coast Guard is also proposing to revise subchapter J to incorporate by reference numerous internationally recognized marine electrical standards which address construction, installation, testing, and safety. Part 110--General Provisions Section 110.01-1. The Coast Guard would revise Sec. 110.1-1, General, to add 46 CFR chapter I, subchapter K, Small Passenger Vessels Carrying more than 150 Passengers or with Overnight Accommodations for more than 49 Passengers, subchapter L, Offshore Supply Vessels, subchapter R, Nautical School Vessels, and subchapter W, Lifesaving Appliances and Arrangements, to the list of subchapters which require electrical installations in accordance with subchapter J. This is not additional regulation; but an entry to correct a prior omission such as with subchapter R since Sec. 167.40-1(a)(2) already requires such compliance; and cross-reference to new subchapters. Section 110.01-3. The Coast Guard would revise Sec. 110.01-3, Repairs, to address alterations as well as repairs. It is proposed that minor alterations on vessels meet the requirements of the regulations in effect on the contract date for the original installation, or the contract date for the alteration. Unlike minor repairs and alterations, major conversions, such as adding a large section to the midbody of the vessel or changing the type or size of the main propulsion engine are considered, under Coast Guard policy, on a case-by-case basis by Commandant (G-MCO) irements of the regulations in effect on the contract date for the original installation, or the contract date for the alteration. Unlike minor repairs and alterations, major conversions, such as adding a large section to the midbody of the vessel or changing the type or size of the main propulsion engine are considered, under Coast Guard policy, on a case-by-case basis by Commandant (G-MCO). Having a single point of review for these situations ensures consistency in application of statutes and regulations. Section 110.10-1. The Coast Guard would update Sec. 110.10-1, Incorporation by reference, to reflect new standards and to update the editions of references already incorporated. This section provides the addresses of organizations which publish the referenced standards. Additionally, the sections affected by the incorporation of standards are identified in Sec. 110.10-1. Section 110.15-1. The Coast Guard would revise Sec. 110.15-1, Definitions, to reflect new and modified terms and definitions used in the subchapter. These minor word changes would bring our regulation terminology in line with internationally accepted language. The proposed changes would remove the reference from ``lifeboats'' and replace it with the SOLAS 74 term ``survival craft'' and would replace the current definition for dead ship with the SOLAS 74 definition, (i.e., remove reference from ``ship service generators'' and replace it with ``auxiliaries''). The definition for ``flashpoint'' would be revised to reflect the current industry definition. Definitions for ``waterproof'', ``watertight'', and ``dripproof'' would be modified with reference to the text in the National Electrical Manufacturers Association (NEMA) and the International Electrotechnical Commission (IEC) enclosure categories for the proposed Sec. 111.01-9, Degree of protection. Proper training and licensing would be added to the list of criteria under the definition for qualified person. This is proposed in order to nd ``dripproof'' would be modified with reference to the text in the National Electrical Manufacturers Association (NEMA) and the International Electrotechnical Commission (IEC) enclosure categories for the proposed Sec. 111.01-9, Degree of protection. Proper training and licensing would be added to the list of criteria under the definition for qualified person. This is proposed in order to quantify the definition since Certificates of Inspection require a vessel to be manned by personnel holding certain licensed and unlicensed ratings. Parts 10 and 12 of 46 CFR detail the training, experience and testing procedures needed to obtain these licenses and documents. On the face of the merchant marine license it states that the holder has been duly examined and found competent. Section 110.20-1. The Coast Guard would revise Sec. 110.20-1, Conditions under which equivalencies may be used, to allow the Commanding Officer, Marine Safety Center (MSC) to accept equivalencies for fittings, materials, apparatus, equipment, or arrangements required by this subchapter. With the consolidation of the Coast Guard's three former merchant marine technical offices into one central location, the opportunity for different interpretations of equivalencies by different Coast Guard offices no longer presents a problem. Allowing the Marine Safety Center to accept equivalencies enables the submitter to send all plans to one point of contact within the Coast Guard. This procedural change would not alter the appeal procedures already contained in 46 CFR 1.03, Rights of appeal. Subpart 110.25. The Coast Guard would revise various paragraphs of subpart 110.25, Plan Submittal, to remove Commandant (G-MMS) as one of the offices to which plans may be submitted. Commandant (G-MMS) does not perform plan review for specific vessels. All vessel plan review is now conducted by the U.S. Coast Guard Marine Safety Center (MSC). Also, several terms in Sec .03, Rights of appeal. Subpart 110.25. The Coast Guard would revise various paragraphs of subpart 110.25, Plan Submittal, to remove Commandant (G-MMS) as one of the offices to which plans may be submitted. Commandant (G-MMS) does not perform plan review for specific vessels. All vessel plan review is now conducted by the U.S. Coast Guard Marine Safety Center (MSC). Also, several terms in Sec. 110.25-1(c) will be changed to reflect the wording found in SOLAS 74 and other international standards. Section 110.30-7. The Coast Guard would revise Sec. 110.30-7, Repairs or alterations, to clarify the material. This section complements Sec. 110.01-3, Repairs, regarding minor and major repairs and alterations. This has been the long-standing regulation in subchapter D: 46 CFR 30.01-10, Application of regulations governing alterations or repairs. Although the application of these regulations has become standard practice for all types of vessels, the Coast Guard now proposes to repeat it in the electrical engineering regulation subchapter to remove any misunderstanding and clarify that this requirement applies to electrical systems on all vessels subject to subchapter J. Subpart 110.35. The Coast Guard would add a new subpart 110.35, Independent Laboratories, which would define Independent Laboratories. An Independent Laboratory will be a laboratory which has been accepted by the Commandant under part 159 of this chapter for the testing of electrical and electronic equipment and other related apparatus. Paragraph (j) of Sec. 110.25-1 would be changed to refer to an Independent Laboratory instead of specifically named laboratories. Part 111--Electric Systems--General Requirements boratories. An Independent Laboratory will be a laboratory which has been accepted by the Commandant under part 159 of this chapter for the testing of electrical and electronic equipment and other related apparatus. Paragraph (j) of Sec. 110.25-1 would be changed to refer to an Independent Laboratory instead of specifically named laboratories. Part 111--Electric Systems--General Requirements Section 111.01-5. The Coast Guard would add electrical cable to the list of equipment in Sec. 111.01-5, Protection from bilge water. In addition to being sound engineering practice, the American Bureau of Shipping (ABS) Rules for Building and Classing Steel Vessels prohibit generator cable installation in the bilge and the Institute of Electrical and Electronic Engineers (IEEE) Standard 45 (Recommended Practice for Electric Installations on Shipboard) recommend not installing any cable in the bilge. Section 111.01-7. The Coast Guard would revise Sec. 111.01-7, Accessibility, to remove specific references, throughout the subchapter, to detailed construction requirements. A new paragraph (b) would be added which would provide general performance and safety guidelines. These revisions would set standards for equipment based on performance criteria and therefore allow the removal of more detailed construction specifications. Section 111.01-9. The Coast Guard would change the title of Sec. 111.01-9, Watertight, waterproof, and dripproof equipment, to Degrees of protection, and revise the section to reflect the revision of Sec. 110.15-1, Definitions. These changes now bring the regulations on enclosures in line with IEC standards while allowing the option of National Electrical Manufacturers Association (NEMA) enclosure selection. Section 111.01-15. The Coast Guard would revise Sec. 111.01-15, Temperature ratings, to require an ambient temperature of 45 deg.C for most electrical equipment in machinery spaces instead of the currently required 50 deg.C now bring the regulations on enclosures in line with IEC standards while allowing the option of National Electrical Manufacturers Association (NEMA) enclosure selection. Section 111.01-15. The Coast Guard would revise Sec. 111.01-15, Temperature ratings, to require an ambient temperature of 45 deg.C for most electrical equipment in machinery spaces instead of the currently required 50 deg.C. The international community has established 45 deg.C as the standard ambient temperature for these shipboard applications. Rotating machinery would still be required to be rated for 50 deg.C because of its inherent heating characteristics, but cable installed in machinery spaces would be rated at 45 deg.C. Control and instrumentation equipment would be rated at 55 deg.C in order to comply with the international requirements. The proposed changes would still allow for derating equipment based on the actual ambient temperature of the space. Section 111.01-17. The Coast Guard would revise Sec. 111.01-17, Nature of electric supply, by renaming the section, Voltage and frequency variations, and deleting specific reference to restrictive standard voltages and frequency as well as deleting table 111.01-17(b), Standard Voltages. The revision would instead reference industry standard operating parameters for electrical machines and apparatus. Sections 111.01-19, 111.01-21, and 111.01-23. The Coast Guard would add three new sections: Sec. 111.01-19, Inclination of the ship, Sec. 111.01-21, Vibration, and Sec. 111.01-23, Humidity. These sections would include requirements for the electrical systems in relation to the inclination of a vessel and those for conditions of vibration and humidity. Section 111.05-1. The Coast Guard would revise Sec. 111.05-1, Purpose, with a minor addition to include ``systems'' as stated in the subpart title. Section 111.05-07. The Coast Guard would revise Sec and Sec. 111.01-23, Humidity. These sections would include requirements for the electrical systems in relation to the inclination of a vessel and those for conditions of vibration and humidity. Section 111.05-1. The Coast Guard would revise Sec. 111.05-1, Purpose, with a minor addition to include ``systems'' as stated in the subpart title. Section 111.05-07. The Coast Guard would revise Sec. 111.05-7, Armored and metallic-sheathed cable, in order to align installation requirements of armor sheathed cable with international standards. Section 111.05-9. The Coast Guard would revise Sec. 111.05-9, Masts, to address lightning protection for vessels with nonmetallic masts. This proposed revision would account for the expanded use of lighter weight composite materials for masts. Section 111.05-19. The Coast Guard would revise Sec. 111.05-19, Tank vessels; grounded distribution systems, to align the systems' voltage limits with the IEC (1000 volts) vice 3000 volts currently mandated in the regulations. This gives the designer of nominal 2400 volt plants the option of a grounded distribution system. Section 111.05-23. The Coast Guard would revise Sec. 111.05-23, Location of ground indicators, to include requirements for branch circuit detection indicators where the circuit is isolated from the main source by a transformer or other device. Normal ground detector indication at the distribution switchboard is required in paragraph (a) for conventional feeder circuits. This proposal extends indication coverage to the load side of isolation devices whose circuits would not be otherwise monitored. Also, this proposal brings to one central location all ground detection device requirements and relieves the engineer of the burden, especially in an emergency, of visiting each transformer switchboard is required in paragraph (a) for conventional feeder circuits. This proposal extends indication coverage to the load side of isolation devices whose circuits would not be otherwise monitored. Also, this proposal brings to one central location all ground detection device requirements and relieves the engineer of the burden, especially in an emergency, of visiting each transformer or isolation device to ascertain the ground condition of the branch circuit. Sections 111.05-25, 111.05-27, and 111.05-29. The Coast Guard would revise Sec. 111.05-25, Ungrounded systems, Sec. 111.05-27, Grounded neutral alternating-current systems, and Sec. 111.05-29, Dual voltage direct-current systems, to offer a greater number of options in ground detection circuitry. The proposed revision would remove restrictive wattage and current limitations on detection circuit components thereby allowing for innovative design and would replace them with performance parameters. Section 111.05-33. The Coast Guard would revise Sec. 111.05-33, Equipment grounding conductors, to require that each equipment grounding conductor be insulated and be of a size at least equal to current carrying conductor. This proposal would align our regulations with the National Electrical Code (NEC). Sections 111.05-37 and 111.05-39. The Coast Guard would consolidate Sec. 111.05-39, Switches and circuit breakers, into Sec. 111.05-37, Overcurrent device. Both sections presently address overcurrent protection devices. Section 111.10-1. The Coast Guard would revise paragraph (a) of Sec. 111.10-1, Definitions, to remove certain cargo refrigeration systems from the list of ship's service electrical loads. These loads are industrial in nature and are not directly related to the safety of the vessel. These refrigeration systems are added to the list of industrial type loads in the same section. Section 111.10-3. The Coast Guard would revise Sec ould revise paragraph (a) of Sec. 111.10-1, Definitions, to remove certain cargo refrigeration systems from the list of ship's service electrical loads. These loads are industrial in nature and are not directly related to the safety of the vessel. These refrigeration systems are added to the list of industrial type loads in the same section. Section 111.10-3. The Coast Guard would revise Sec. 111.10-3, Two generating sets, to add the requirement that a Mobile Offshore Drilling Unit (MODU) must have at least two ship's service generating sets. This is presently a requirement of the International Maritime Organization (IMO) MODU Code. The Coast Guard proposes the inclusion since subchapter I-A for MODU Inspection and Certification references subchapter J for their electrical systems. Section 111.10-4. The Coast Guard would revise Sec. 111.10-4, Power requirements; generating sets, to define the required generating capacity. The changes would result in regulations which mirror the requirements of SOLAS 74. The Coast Guard would revise paragraph (b) to clarify the fact that the capacity of the ship's service generating set or sets must be sufficient to carry the ship's service loads with the largest ship's service generator stopped. The Coast Guard would revised paragraph (d) to ensure that propulsion-plant loads do not impact on ship's service loads when these loads are supplied by a common generator. New paragraphs (e) and (f) would be added specifically to address main-engine-dependent generators. The proposed regulation reflects a harmonization with international standards, recognized classification society requirements, and present industry practice for these types of generators. Section 111.10-7. The Coast Guard would revised paragraph (b) of Sec. 111.10-7, Dead ship, by adding a sentence referencing additional existing requirements contained in Sec. 112.05-3 of this chapter. These requirements refer to the main and emergency bus-tie. Sections 111.10-9 and 111.10-11 ed classification society requirements, and present industry practice for these types of generators. Section 111.10-7. The Coast Guard would revised paragraph (b) of Sec. 111.10-7, Dead ship, by adding a sentence referencing additional existing requirements contained in Sec. 112.05-3 of this chapter. These requirements refer to the main and emergency bus-tie. Sections 111.10-9 and 111.10-11. The Coast Guard would revise Sec. 111.10-9, Ship's service supply transformers; 2 required, to clarify the intent of the requirement and bring the requirements of Sec. 111.10-11, Power requirements; transformers under this one section. Section 111.12-1. The Coast Guard would revised paragraph (a) of Sec. 111.12-1, Prime movers, to incorporate American Bureau of Shipping (ABS) Rules for prime movers, paragraph (b) to clarify that all generator prime movers need a governor, and paragraph (c) to remove the exemption from the automatic shut down in case of loss of lubricating oil. Section 111.12-5. The Coast Guard would revise paragraph (a) of Sec. 111.12-5, Generator construction and testing, to reflect a change in the ABS Rules numbering system and would remove the designation ``(a)'' from the paragraph. Paragraphs (b), (c), and (d) would be removed. Section 111.12-7. The Coast Guard would revise paragraph (a) of Sec. 111.12-7, Voltage regulation and parallel operation, to reflect a change in ABS Rules numbering system. Sections 111.15-1, 111.15-2, and 111.15-3. The Coast Guard would revise Sec. 111.15-1, General Sec. 111.15-2, Battery construction, and Sec. 111.15-3, Battery categories, to eliminate restrictive construction details and to allow the use of different types of batteries, including sealed batteries and other designs. The specific size requirement in paragraph (c) of Sec. 111.15-2 would be removed and reclassification would be allowed under paragraph (d) of Sec. 111.15-3. Additionally, the Coast Guard proposes a new paragraph (d) in Sec 15-3, Battery categories, to eliminate restrictive construction details and to allow the use of different types of batteries, including sealed batteries and other designs. The specific size requirement in paragraph (c) of Sec. 111.15-2 would be removed and reclassification would be allowed under paragraph (d) of Sec. 111.15-3. Additionally, the Coast Guard proposes a new paragraph (d) in Sec. 111.15-2 be added as a performance measure to address a battery's suitability for installation in the marine environment. Section 111.15-5. The Coast Guard would revised paragraph (a) in Sec. 111.15-5, Battery installations, by deleting the reference to specific test laboratories. All electrical equipment and laboratory testing requirements for hazardous locations would be addressed in subpart 111.105, Hazardous Locations. Additionally, the Coast Guard would allow for the expanded use of internationally available electrical equipment by providing reference to IEC hazardous location classifications. The Coast Guard would amend Sec. 111.15-5(c), Small batteries, to allow liberal storage of small-size sealed batteries. This is possible due to the reduced hazard associated with sealed equipment. The Coast Guard would eliminate paragraph 111.15-5(e), Tiers. This requirement is redundant with the spacing requirement specified in paragraph 111.15-5(d), Battery trays. The remaining paragraphs (f), (g) and (h) would be renamed (e), (f) and (g). Section 111.15-10. The Coast Guard would revise paragraph (g) of Sec. 111.15-10, Ventilation, to explain the intent of ventilation requirements for small battery installations. If the battery box were in a non-environmentally-controlled location, simple vent openings may allow the ingress of water. A statement on preventing ingress would be added. Section 111.15-20. The Coast Guard would revise Sec. 111.15-20, Conductors, to put the accepted installation practices presently included in this section into proper terminology quirements for small battery installations. If the battery box were in a non-environmentally-controlled location, simple vent openings may allow the ingress of water. A statement on preventing ingress would be added. Section 111.15-20. The Coast Guard would revise Sec. 111.15-20, Conductors, to put the accepted installation practices presently included in this section into proper terminology. The requirements in paragraphs (b) and (c) would be combined into one paragraph. Section 111.15-30. The Coast Guard would revise Sec. 111.15-30, Battery chargers, to eliminate specific construction requirements for battery chargers. In their place, the Coast Guard proposes certain performance requirements. Section 111.20-1. The Coast Guard would revise Sec. 111.20-1, General requirements, to reflect internationally accepted practices for transformer construction, installation and protection by allowing not only the winding but also the enclosure to provide the necessary protection. Section 111.20-15. The Coast Guard would revise Sec. 111.20-15, Transformer overcurrent protection, to reflect internationally accepted practices for transformer overcurrent protection by allowing a choice of standards. Section 111.25-5. The Coast Guard would revise paragraph (a) of Sec. 111.25-5, Marking, to allow nameplate markings in accordance with the practices of the IEC as an alternative to the present National Electrical Code requirement. Section 111.30-1. The Coast Guard would revise Sec. 111.30-1, Location and installation, to require switchboard installation to follow industry practice by removing specific construction ast Guard would revise paragraph (a) of Sec. 111.25-5, Marking, to allow nameplate markings in accordance with the practices of the IEC as an alternative to the present National Electrical Code requirement. Section 111.30-1. The Coast Guard would revise Sec. 111.30-1, Location and installation, to require switchboard installation to follow industry practice by removing specific construction detailed regulatory language and instead referring to the appropriate guidance of IEEE Standard 45. Section 111.30-4. The Coast Guard would revise Sec. 111.30-4, Circuit breakers removable from front, to allow an alternative method of circuit breaker installation. This would permit the circuit breaker to be hard-wired to the switchboard if: (1) The switchboard is divided into two or more sections that can be split by disconnecting a link between a section of the switchboard, and (2) the connection of generators and duplicated equipment is equalized between the sections of the main bus. This allows for the capability of de-energizing a section of the switchboard without shutting down the power supply or degrading the continuity of power supply to vital loads. Section 111.30-5. The Coast Guard would revise Sec. 111.30-5, Construction, to remove detailed switchboard construction requirements and incorporate international consensus standards (IEEE Standard 45 and IEC Publications 92-302/92-503). Sections 111.30-9, 111.30-11, and 111.30-13. The Coast Guard would eliminate Sec. 111.30-9, Mechanical protection, Sec. 111.30-11, Mats or gratings, and Sec. 111.30-13, Grounding. The requirements of these sections are included in the industry practices of the IEEE Standard 45 and the IEC Publications. Section 111.30.-19. The Coast Guard would revise Sec. 111.30-19 Buses and wiring. Paragraph (a) would be revised to allow for the guidance of international performance standards instead of the present detailed technical requirements tings, and Sec. 111.30-13, Grounding. The requirements of these sections are included in the industry practices of the IEEE Standard 45 and the IEC Publications. Section 111.30.-19. The Coast Guard would revise Sec. 111.30-19 Buses and wiring. Paragraph (a) would be revised to allow for the guidance of international performance standards instead of the present detailed technical requirements. Paragraphs (b) through (e) would be deleted because the information they contain is covered by proposed paragraph (a). Paragraph (f) would be renamed paragraph (b) and would be revised to allow for the use of small-conductor-size cable, such as ribbon cable, for instrumentation and control circuitry, as is common industry practice. Section 111.30-21. The Coast Guard would eliminate Sec. 111.30-21, High temperature devices. This design specification would be addressed in the requirements of the appropriate industry standards of the IEEE and IEC and need not be repeated here. Section 111.30-23. The Coast Guard would eliminate Sec. 111.30-23, Medium voltage switchboards. These requirements will be part of the proposed revision of Sec. 111.30-5, Construction. Section 111.30-24. The Coast Guard would revise Sec. 111.30-24, Generation systems greater than 3000 kw, to modify the exemption for MODUs to split the switchboard when the total generator power exceeds 3000 kw. The IMO MODU Code requires self-propelled MODUs to have a split switchboard when the total installed generator capacity exceeds 3 Megawatts (3000 kw). Therefore the exemption will apply only to nonself-propelled MODUs. Section 111.30-29. The Coast Guard would revise Sec. 111.30-29, Emergency switchboards, by adding paragraphs (g), (h) and (i). These paragraphs are presently contained in part 112. The purpose of this change is to consolidate all of the requirements for the emergency- switchboard instrumentation and equipment into one section. Section 111.30-31. The Coast Guard would delete Sec. 111.30-31, Tests tion 111.30-29. The Coast Guard would revise Sec. 111.30-29, Emergency switchboards, by adding paragraphs (g), (h) and (i). These paragraphs are presently contained in part 112. The purpose of this change is to consolidate all of the requirements for the emergency- switchboard instrumentation and equipment into one section. Section 111.30-31. The Coast Guard would delete Sec. 111.30-31, Tests. Presently this section requires switchboards to be tested to an American Bureau of Shipping requirements. American Bureau of Shipping Rules do not address the testing of switchboards. Section 111.33-3. The Coast Guard would replace the descriptive nameplate requirements of Sec. 111.33-3, Nameplate data, for semiconductor rectifier systems with industry practice according to international standards. Section 111.33-5. The Coast Guard would replace the descriptive installation requirements of Sec. 111.33-5, Installation, for semiconductor rectifier systems with industry practice according to international standards. Section 111.33-11. The Coast Guard would revise Sec. 111.33-11, Propulsion systems, to reflect the current American Bureau of Shipping numbering system regarding semiconductor rectifier systems. Section 111.35-1. The Coast Guard would revise Sec. 111.35-1, Electrical propulsion installations, to reflect the current American Bureau of Shipping numbering system. Section 111.40-1, 111.40-5, and 111.40-7. The Coast Guard would remove Sec. 111.40-1, Panelboard, standard, to eliminate the requirement of meeting a specific standard and thereby allowing the use of panelboards which are designed and constructed according to sound engineering practice. Likewise, the Coast Guard would revise Sec. 111.40-5, Enclosure, and Sec. 111.40-7, Location, to allow the installation of panelboards with a suitable degree of protection to be installed in the weather. This change allows more latitude in the electrical arrangement on the ship without reducing personnel safety requirements. Section 111.50-2 structed according to sound engineering practice. Likewise, the Coast Guard would revise Sec. 111.40-5, Enclosure, and Sec. 111.40-7, Location, to allow the installation of panelboards with a suitable degree of protection to be installed in the weather. This change allows more latitude in the electrical arrangement on the ship without reducing personnel safety requirements. Section 111.50-2. The Coast Guard would add a new Sec. 111.50-2, Systems integration. This new section would reflect the need to consider component compatibility within each overcurrent protection system. Section 111.50-3. The Coast Guard would revise paragraphs (c), (d), (f) and (h)(2) of Sec. 111.50-3, Protection of conductors, to allow the use and incorporate the requirements of the IEC for fuses, circuit breakers, thermal devices and ground conductors. Section 111.52-1. The Coast Guard would correct Sec. 111.52-1, General, to identify the physical unit (i.e., ``current'') needed to be calculated when performing short-circuit current calculations. Section 111.52-5. The Coast Guard would revise Sec. 111.52-5, Systems 1500 kilowatts or above, to allow several additional methods of short-circuit current calculations. This would ensure that the appropriate method of short-circuit current calculation is available to the designer as well as the plan reviewer. Section 111.53-1. The Coast Guard would revise paragraph (a)(1) of Sec. 111.53-1, General, to eliminate specific reference to parts E and F of the National Electrical Code relative to fuses. The revision would add the option of meeting the general provisions of IEC internationally recognized standards. Additionally, the Coast Guard would revise paragraph (a)(3) to eliminate restrictive reference to Underwriters Laboratories, Inc. This would expand industry's options to list fuses with any Independent Laboratory. The Coast Guard would revise paragraph ical Code relative to fuses. The revision would add the option of meeting the general provisions of IEC internationally recognized standards. Additionally, the Coast Guard would revise paragraph (a)(3) to eliminate restrictive reference to Underwriters Laboratories, Inc. This would expand industry's options to list fuses with any Independent Laboratory. The Coast Guard would revise paragraph (b) to eliminate prohibitive reference to Edison-base fuses. The Coast Guard recognizes that systems designed and built to IEC and/or CEN standards may contain these fuses. It is also recognized that many Maritime Administration (MARAD) Ready Reserve Force reflagged vessels have been operating with such equipment for years. The Coast Guard, however, maintains its prohibition of renewable-link cartridge fuses because it is considered a severe safety hazard in that a link of a higher than recommended current value might be placed in a jacket marked with a lower value and the fault be undetectable. The Coast Guard would add a new paragraph (c) to provide for the ability to test for fuse condition, particularly for installations utilizing Edison- base fuses, since the glass or plastic link protector inhibits the readily available test points offered by a more common cartridge fuse. Section 111.54-1. The Coast Guard would revise Sec. 111.54-1, Circuit breakers, to include reference to and the allowance of internationally recognized standards and at the same time test for fuse condition, particularly for installations utilizing Edison- base fuses, since the glass or plastic link protector inhibits the readily available test points offered by a more common cartridge fuse. Section 111.54-1. The Coast Guard would revise Sec. 111.54-1, Circuit breakers, to include reference to and the allowance of internationally recognized standards and at the same time eliminate reference to restrictive and specific construction standards. Section 111.55-1, 111.55-5, 111.55-7, and 111.55-9. The Coast Guard would delete Sec. 111.55-5, Knife switches, Sec. 111.55-7, Snap switches, and Sec. 111.55-9, Enclosed switches. These requirements do not provide an additional level of safety beyond that ensured by compliance with Sec. 111.55-1, General. Subpart 111.57. The Coast Guard would eliminate subpart 111.57, Current-Limiting Devices. The operating and design characteristics of current limiting devices would be included in the revision of subpart 111.53, Fuses, and subpart 111.54, Circuit Breakers. This, in turn, reduces repetitive and unnecessary regulation. Section 111.59-1. The Coast Guard would rewrite Sec. 111.59-1, General, to eliminate paragraph (b) and the requirement that busways meet a specific construction standard, as the performance of the component is established by compliance with paragraph (a). Section 111.59-3. The Coast Guard would revise Sec. 111.59-3, No mechanical cooling, to correct an omission. In the present version, the regulations state that ``A busway must need mechanical cooling * * *'' which is opposite to the intent of this section. Section 111.60-1. The Coast Guard would revise Sec. 111.60-1, Cable construction and testing, to align our regulation language with that of the 1983 edition of IEEE Standard 45 revise Sec. 111.59-3, No mechanical cooling, to correct an omission. In the present version, the regulations state that ``A busway must need mechanical cooling * * *'' which is opposite to the intent of this section. Section 111.60-1. The Coast Guard would revise Sec. 111.60-1, Cable construction and testing, to align our regulation language with that of the 1983 edition of IEEE Standard 45. Additionally, the Coast Guard would propose to include, as acceptable, cable that is designed, constructed, tested and installed in accordance with the international standards of IEC Publications 92-3 and certain 92-350 series as well as several MIL Specification cables. Sections 111.60-2 and 111.60-6. The Coast Guard would add new Sec. 111.60-2, Specialty cable for communication and RF applications, and Sec. 111.60-6, Fiber optic cable, to include requirements for specialty electrical cables and optical fiber cables. The proposed requirements address installation and flammability characteristics for these cables. The Coast Guard feels this is necessary because of the present lack of guidance for this relatively new equipment now on board or contemplated for installation on board certificated vessels and because of the larger fire load the cable represents. Section 111.60-3. The Coast Guard would revise Sec. 111.60-3, Cable application, to include the applicable requirements of IEC Publication 352 and to assure proper derating of cables according to type construction. Section 111.60-4. The Coast Guard would revise Sec. 111.60-4, Minimum cable conductor size, to include instrumentation cable with the thermocouple and pyrometer group. Mention of general instrumentation cable was unintentionally omitted from the regulations during the last revision. Section 111.60-5. The Coast Guard would revise Sec. 111.60-5, Cable installation, to include reference to the installation of cables constructed in accordance with the international standard IEC Publication 92-3 and the IEC 92-350 series h the thermocouple and pyrometer group. Mention of general instrumentation cable was unintentionally omitted from the regulations during the last revision. Section 111.60-5. The Coast Guard would revise Sec. 111.60-5, Cable installation, to include reference to the installation of cables constructed in accordance with the international standard IEC Publication 92-3 and the IEC 92-350 series. Section 111.60-11. The Coast Guard would revise Sec. 111.60-11, Wire, to expand the choices available for shipboard wiring. The current requirements are too restrictive and do not constitute an appreciable increase in safety beyond the proposed reduction in those requirements. Section 111.60-13. The Coast Guard would revise paragraph (a) of Sec. 111.60-13, Flexible electric cord and cables, to remove the restrictions presently governing the use of flexible cord and cables. The proposed change allows compliance with a larger number of nationally-recognized standards. Section 111.60-17. The Coast Guard would revise Sec. 111.60-17, Connections and terminations. The current regulations are merely a narrative describing standard marine practice. The proposed revision would outline specific installation criteria for connectors and terminals. Section 111.60-19. The Coast Guard would revise Sec. 111.60-19, Cable splices, to reflect current industry practice as outlined in the internationally accepted IEEE Standard 45. Section 111.60-21. The Coast Guard would revise Sec. 111.60-21, Cable insulation tests, to reflect a change in numbering system of the referenced IEEE standard. Section 111.60-23. The Coast Guard would add a new Sec. 111.60-23, Type MC cable, to address the lack of requirements primarily on offshore production platforms. However, the installation of this cable is not limited to offshore platform applications and may be used as shipboard cable provided certain installation requirements are followed. Subpart 111.70 m of the referenced IEEE standard. Section 111.60-23. The Coast Guard would add a new Sec. 111.60-23, Type MC cable, to address the lack of requirements primarily on offshore production platforms. However, the installation of this cable is not limited to offshore platform applications and may be used as shipboard cable provided certain installation requirements are followed. Subpart 111.70. The Coast Guard would revise subpart 111.70, Motor Circuits, Controllers and Protection, to reflect internationally recognized classification society standards, practices and requirements which do not rely solely on the shoreside code of the National Electrical Code. Additionally, the revision will eliminate obsolete requirements. Section 111.75-1. The Coast Guard would revise paragraph (a) of Sec. 111.75-1, Lighting feeders, to replace the term ``fire screen'' with the term ``fire'' to agree with SOLAS 74, and include reference to low location egress lighting. The Coast Guard would eliminate paragraph (c). This requirement does not elevate the overall safety level of the vessel. The Note, however, is part of the section and is retained. Section 111.75-5. The Coast Guard would delete the voltage specific requirements of lighting circuits by deleting paragraph (b), Voltages, in Sec. 111.75-5, Lighting branch circuits, and the remaining paragraphs would be re-lettered and re-numbered accordingly. The Coast Guard would redesignate paragraph (c), Connected load, as paragraph (b) and revise the narrative concerning connected loads. The removed narrative is standard electrical practice and need not be specified in the regulations. The Coast Guard would redesignate paragraph (e), overcurrent protection, as paragraph (d), redesignate paragraph (f), 25 or 30 ampere lighting branch circuits, as paragraph (e), and revise the new paragraph (d) to remove the specifications for the minimum conductor sizes. The requirements for these loads required by proposed revisions of Sec tice and need not be specified in the regulations. The Coast Guard would redesignate paragraph (e), overcurrent protection, as paragraph (d), redesignate paragraph (f), 25 or 30 ampere lighting branch circuits, as paragraph (e), and revise the new paragraph (d) to remove the specifications for the minimum conductor sizes. The requirements for these loads required by proposed revisions of Sec. 111.60-3, Cable application, and Sec. 111.60-4, Minimum cable conductor size, are adequate. The Coast Guard would eliminate paragraph (g), connections to screw-shell lampholders, as it is considered standard practice and need not appear in regulation. Section 111.75-15. The Coast Guard would revise paragraph (c), Illumination of passenger and crew spaces, in Sec. 111.75-15 to eliminate restrictive wording and replace this requirement with a performance requirement concerning normal habitability and safe egress under emergency conditions. Section 111.75-16. The Coast Guard would revise Sec. 111.75-16, Lifeboat and liferaft floodlights, to replace the terms ``lifeboat'' and ``liferaft'' with the term ``survival craft'' to agree with SOLAS 74 terminology. Section 111.75-17. The Coast Guard would delete paragraph (d)(1) of Sec. 111.75-17, Navigation lights, which requires navigation light fixtures to be approved by the Commandant, as this would no longer be required. The Coast Guard proposes instead that paragraph (d) be further revised to incorporate labeling requirements to show compliance with UL 1104 by an Independent Laboratory. The Coast Section 111.75-17. The Coast Guard would delete paragraph (d)(1) of Sec. 111.75-17, Navigation lights, which requires navigation light fixtures to be approved by the Commandant, as this would no longer be required. The Coast Guard proposes instead that paragraph (d) be further revised to incorporate labeling requirements to show compliance with UL 1104 by an Independent Laboratory. The Coast Guard would delete paragraph (f), Light screens. This requirement is clearly stated in the COLREGS Annex I Rule 5 and in 33 U.S.C. 1602 and need not be repeated here. Section 111.75-18. The Coast Guard would revise Sec. 111.75-18, Signaling lights, to reflect SOLAS 74 Regulation V/11 for applicability and to reduce specific construction details. Section 111.75-20. The Coast Guard would revise Sec. 111.75-20, Lighting fixtures, to modify paragraph (a) to include UL's deleting UL 595 (Marine-Type Electric Lighting Fixtures) and incorporating specific Marine requirements into the respective fixture type standards (i.e., UL 1570 is for Fluorescent Lighting Fixtures, UL 1571 is for Incandescent Lighting Fixtures, etc.). Also, the Coast Guard would add an additional paragraph (e) which would address the installation of non-emergency interior and decorative lighting in environmentally- controlled spaces. Also, requirements related to shock and vibration which may be encountered in the marine environment will be addressed. Both paragraphs will reference additional international standard options. Sections 111.77-3, 111.77-5, 111.77-7, 111.77-9, and 111.77-11. The Coast Guard would eliminate Sec. 111.77-3, Electric cooking equipment, Sec. 111.77-5, Electric motor-operated appliances, Sec. 111.77-7, Dishwashers, Sec. 111.77-9, Refrigerators, and Sec. 111.77-11, Refrigerated drinking water coolers, and replace them with internationally recognized safety standards onal standard options. Sections 111.77-3, 111.77-5, 111.77-7, 111.77-9, and 111.77-11.

Selection of safe appliances, based on industry construction and testing standards for use on commercial vessels, is at the option of the vessel owner. Section 111.79-1. The Coast Guard would revise Sec. 111.79-1, Receptacle outlets; general, to remove specific construction requirements and to allow for more flexibility in installations. Section 111.79-5. The Coast Guard would eliminate Sec. 111.79-5, Damp or wet locations and weather locations, and incorporate more general industry standards and practices under Sec. 111.79-1, Receptacle outlets; general, in the proposed revision of paragraphs (c) and (d). Section 111.79-7. The Coast Guard would remove the detailed construction requirements for receptacle components in Sec. 111.79-7, No live parts, and replace them with performance requirements. Section 111.79-13. The Coast Guard would revise and rename Sec. 111.79-13, Different potentials on a vessel, to read, Different voltages and power types, to remove any ambiguity and more clearly explain the intent of the regulation. Sections 111.81-1 and 111.81-5. The Coast Guard would delete Sec. 111.81-5, National Electrical Code, and the text, which addresses the NEC requirements for outlet boxes and junction boxes, would be relocated to new paragraph (d) in Sec. 111.81-1, Outlet boxes and junction boxes: General. The new Sec. 111.81-1(d) would address the general requirements for junction boxes in terms of U.S. national standards and introduce the option of international standards as well. This change would also consolidate the requirements for junction boxes into one section. Section 111.81-7 boxes, would be relocated to new paragraph (d) in Sec. 111.81-1, Outlet boxes and junction boxes: General. The new Sec. 111.81-1(d) would address the general requirements for junction boxes in terms of U.S. national standards and introduce the option of international standards as well. This change would also consolidate the requirements for junction boxes into one section. Section 111.81-7. The Coast Guard would rename Sec. 111.81-7, Degree of protection. The Coast Guard would also propose to revise this section by incorporating industry accepted standards and terminology, both domestic and international. Section 111.81-9. The Coast Guard would revise Sec. 111.81-9, Mounting, to remove specific installation restrictions and replace them with performance requirements. Section 111.81-11. The Coast Guard would eliminate Sec. 111.81-11, Penetration of walls. This regulation is unnecessary since, by definition, a watertight enclosure must retain its integrity to be considered watertight. Section 111.81-13. The Coast Guard would eliminate Sec. 111.81-13, Construction. General construction requirements for outlet and junction boxes are now addressed in proposed paragraphs 111.81-7(a) and (b). Section 111.83-3. The Coast Guard would remove Sec. 111.83-3, Spacing: Live parts and live parts and ground, as the subject is addressed in Sec. 111.01-7, Accessibility. Subpart 111.85. The Coast Guard would revise subpart 111.85, Electric Oil Immersion Heaters, to exempt oil immersion heaters where it can be shown that the operating temperature of the heater can never reach the ignition temperature of the oil or vapor with which it is in contact. Section 111.87-3. The Coast Guard would revise paragraph (a) of Sec. 111.87-3, General requirements, to remove construction requirements to specific standards and replace them with reference to more general safety related requirements. Subpart 111.89. The Coast Guard would eliminate subpart 111.89, Motion Picture Projectors nition temperature of the oil or vapor with which it is in contact. Section 111.87-3. The Coast Guard would revise paragraph (a) of Sec. 111.87-3, General requirements, to remove construction requirements to specific standards and replace them with reference to more general safety related requirements. Subpart 111.89. The Coast Guard would eliminate subpart 111.89, Motion Picture Projectors. This regulation references a standard that is no longer pertinent to the marine environment. State-of-the-art technology has substituted video tape and laser disk players which do not present the same level of risk as projectors. Section 111.91-1. The Coast Guard would revise and rename Sec. 111.91-1, Control and interlock circuits, to require elevator and dumbwaiter power, control, interlock, and switch circuitry to meet the requirements of American National Standards Institute, Inc. (ANSI A17.1). Section 111.91-3. The Coast Guard would eliminate Sec. 111.91-3, Control switches. This design standard is not pertinent to the performance of the device. Section 111.95-3. The Coast Guard would eliminate the detailed construction requirements of paragraphs (a) through (e) of Sec. 111.95- 3, General requirements. Paragraph (f) would be renamed (b) and retained. New general requirements will be set forth in a proposed revision to reference industry accepted standards (both national and international) and other proposed requirements for Degree of Protection and Accessibility. Section 111.95-5. The Coast Guard would eliminate the detailed requirements of Sec. 111.95-5, Detail construction requirements. Sufficient guidance is afforded in the proposed revision of Sec. 111- 95-3, General requirements. Section 111.95-7. The Coast Guard would delete figures 111.95-7 national and international) and other proposed requirements for Degree of Protection and Accessibility. Section 111.95-5. The Coast Guard would eliminate the detailed requirements of Sec. 111.95-5, Detail construction requirements. Sufficient guidance is afforded in the proposed revision of Sec. 111- 95-3, General requirements. Section 111.95-7. The Coast Guard would delete figures 111.95-7 (e)(1) through (e)(5), which address typical boat winch wiring diagrams and arrangement drawings. The figures create confusion in the application of lifeboat davit switches and serve no useful or safety purpose. Section 111.97-5. The Coast Guard would revise paragraph (c) of Sec. 111.97-5, Electric and hydraulic power supply, to reduce the required capacity of an accumulator tank on a hydraulic system common to more than one power-operated watertight door. The present regulation requires the tank to have sufficient capacity to open and close all doors three times. Consistent with SOLAS 74, the proposed requirement states that the capacity must be sufficient to close all doors two times and open all doors once. Subpart 111.99. The Coast Guard would revise subpart 111.99, Firescreen Door Holding and Release Systems, to replace the term ``fire screen'' with the term ``fire'' to provide consistency with the terminology of SOLAS 74, Regulation II-2/47. Section 111.99-1. The Coast Guard would expand the scope of Sec. 111.99-1, Applicability, to address fire doors installed on all vessels which require fire doors. The subchapters in 46 CFR containing requirements for specific vessel types all require fire doors to meet subpart 111.99. screen'' with the term ``fire'' to provide consistency with the terminology of SOLAS 74, Regulation II-2/47. Section 111.99-1. The Coast Guard would expand the scope of Sec. 111.99-1, Applicability, to address fire doors installed on all vessels which require fire doors. The subchapters in 46 CFR containing requirements for specific vessel types all require fire doors to meet subpart 111.99. Subpart 111.105. The Coast Guard would add, delete and revise sections of subpart 111.105, Hazardous Locations, to reflect current national standards and recognized classification society rules. Additionally, means of alternative compliance to these particulars will be provided by incorporating by reference international standards (i.e., IEC, CEN and IEEE). Specific paragraphs and sections affected follow. Section 111.105-1. The Coast Guard would revise Sec. 111.105-1, Applicability, to remove the restriction to the National Electrical Code references to hazardous locations and provide options from IEC Publication 79 series. Section 111.105-3. The Coast Guard would add a new Sec. 111.105-3, General requirements, to provide basic guidance to hazardous location information and to set forth the appropriate standards. Section 111.105-5. The Coast Guard would rename the section and delete the subject material of Sec. 111.105-5, National Electrical Code, whose guidance has been superseded by proposed new Sec. 111.105- 3. Proposed Sec. 111.105-5, System integrity, would now address the prohibition of mixing the requirements of the NEC with IEC equipment and systems since, although equivalent in level of safety, they differ in the manner by which this is achieved. Section 111.105-7, 111.105-9, 111.105-11, and 111.105-23. The Coast Guard would revise Sec. 111.105-7, Approved equipment, Sec. 111.105-9, Explosionproof equipment, Sec. 111.105-11, Intrinsically safe systems, and Sec ibition of mixing the requirements of the NEC with IEC equipment and systems since, although equivalent in level of safety, they differ in the manner by which this is achieved. Section 111.105-7, 111.105-9, 111.105-11, and 111.105-23. The Coast Guard would revise Sec. 111.105-7, Approved equipment, Sec. 111.105-9, Explosionproof equipment, Sec. 111.105-11, Intrinsically safe systems, and Sec. 111.105-23, Fan motors, to replace the specifically mentioned test facilities with phraseology that will provide industry with a greater number of options for product testing. Section 111.105-10. The Coast Guard would eliminate Sec. 111.105- 10, Purged and pressurized equipment. Its content, with options, would be sufficiently presented in proposed Sec. 111.105-7, Approved equipment. Section 111.105-11. The Coast Guard would revise paragraph (a) of Sec. 111.105-11, Intrinsically safe systems, to remove the restriction of specific test laboratories and to add additional accepted international standards to which equipment may be tested. Section 111.105-11. The Coast Guard would add paragraphs (b)(3) and (b)(4) in Sec. 111.105-11, Intrinsically safe systems, as an additional safety measure and to conform with accepted industry practices as stated in the IEEE Standard 45. Also, the requirements in Sec. 111.105- 11(e) are to be relocated to proposed Sec. 110.25-1(c)(12) to consolidate the requirements relating to plan submittal. Sections 111.105-15 and 111.105-17. The Coast Guard would delete Sec. 111.105-15, Wiring methods for Class I hazardous locations, and Sec. 111.105-17, Wiring methods for Class II and Class III hazardous locations. A new Sec. 111.105-15 entitled, Additional methods of protection, and a new Sec. 111.105-17 entitled, Wiring methods for hazardous locations, are proposed. These would permit the use of conduit systems as allowed by the National Electrical Code and afford a greater variety of equipment complying with internationally accepted standards. Section 111.105-19 I and Class III hazardous locations. A new Sec. 111.105-15 entitled, Additional methods of protection, and a new Sec. 111.105-17 entitled, Wiring methods for hazardous locations, are proposed. These would permit the use of conduit systems as allowed by the National Electrical Code and afford a greater variety of equipment complying with internationally accepted standards. Section 111.105-19. The Coast Guard would revise Sec. 111.150-19, Switches, to conform with reference to proposed revisions which reflect the acceptance of equipment meeting international standards. Sections 111.105-21, 111.105-23, and 111.105-25. The Coast Guard would revise the title and text of Sec. 111.105-21, Fans, to consolidate the guidance in Sec. 111.105-23, Fan motors, and Sec. 111.105-25, Ventilation ducts, thereby eliminating those two sections. Section 111.105-29. The Coast Guard would revise paragraph (a) In Sec. 111.105-29, Combustible liquid cargo carriers, to include requirements for submersible pumps on vessels with combustible liquid cargoes having flashpoints 60 deg.C or higher. This reflects the requirements of the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code), which allows for submersible cargo pumps to be used on vessels with a cargo having a flashpoint exceeding 60 deg.C. The Coast Guard would add paragraph (c) to include hazardous area classification requirements for vessels carrying a cargo with a flashpoint of 60 deg.C or higher which is heated to within 15 deg.C of its flashpoint. This reflects the requirements of the IBC Code. Section 111.105-31. The Coast Guard would revise Sec. 111.105-31, Flammable or combustible cargo with a flashpoint below 60 degrees C (140 degrees F), liquid sulfur and inorganic acid carriers, to include information in agreement with the wording and guidance in 33.14 (Electrical Installations on Tank Vessels) of IEEE Standard 45 ts flashpoint. This reflects the requirements of the IBC Code. Section 111.105-31. The Coast Guard would revise Sec. 111.105-31, Flammable or combustible cargo with a flashpoint below 60 degrees C (140 degrees F), liquid sulfur and inorganic acid carriers, to include information in agreement with the wording and guidance in 33.14 (Electrical Installations on Tank Vessels) of IEEE Standard 45. The Coast Guard would revise paragraph (e) to include internationally accepted terminology of the IEC concerning zone descriptions of hazardous locations. The Coast Guard would revise paragraph (l) by adding new paragraphs (l)(3) and (l)(4) to include requirements for electrical installations in hazardous locations on board vessels with cargoes with flashprints below 60 deg.C in accordance with international standards. Section 111.105-32. The Coast Guard would revise the title of Sec. 111.105-32, Bulk liquefied gas and ammonia carriers, and paragraph (e), which addresses the requirements for submersible cargo pumps in bulk liquefied flammable gas and ammonia carriers, and would reference the requirements of Sec. 111.105-31(d) for submersible pumps. Section 111.105-35. Presently, when a vessel is issued a Certificate of Inspection to carry coal, the certificate does not differentiate between the types of coal. This allows a vessel to carry both types, bituminous and anthracite coal. The Coast Guard would revise Sec. 111.105-35 to require that vessels carrying coal of any type be subject to the same hazardous area classification requirements. Therefore, the vessel's hazardous area plan should address the worst case scenario. Section 111.105-37. The Coast Guard would revise Sec. 111.105-37, Flammable anesthetics, to reflect a change in name and number of the referenced NFPA standard. Section 111.105-39. The Coast Guard would revise and rename Sec coal of any type be subject to the same hazardous area classification requirements. Therefore, the vessel's hazardous area plan should address the worst case scenario. Section 111.105-37. The Coast Guard would revise Sec. 111.105-37, Flammable anesthetics, to reflect a change in name and number of the referenced NFPA standard. Section 111.105-39. The Coast Guard would revise and rename Sec. 111.105-39, Gasoline or other highly volatile motor fuel carried in vehicles, to reflect current recognized classification society rules regarding requirements for vessels carrying vehicles with fuel in their tanks. Additionally, means of alternative compliance to classification society rules is provided by citing IEC Zone classification. Section 111.105-40. The Coast Guard would introduce a new Sec. 111.105-40, Additional requirements for RO/RO vessels, to reflect current international classification society rules regarding RO/RO vessels. Additionally, means of alternative compliance is provided by citing IEC Zone classification. Section 111.105-41. The Coast Guard would revise Sec. 111.105-41, Battery rooms, to incorporate the provisions of internationally recognized IEEE Standard 45. Section 111.105-45. The Coast Guard would add Sec. 111.105-45, Vessels carrying agricultural products, to identify hazardous locations on vessels carrying certain agricultural products in bulk due to the hazards associated with grain dust. The proposed requirements are identical to the information published in Navigation and Vessel Inspection circular (NVIC) 9-84 ``Electrical Installations in Agricultural Dust Locations'' which has been Coast Guard policy since this subchapter was last revised. Section 111.105-47. The Coast Guard would add a new Sec. 111.105- 47, Duct keel ventilation or lighting, to reflect d with grain dust. The proposed requirements are identical to the information published in Navigation and Vessel Inspection circular (NVIC) 9-84 ``Electrical Installations in Agricultural Dust Locations'' which has been Coast Guard policy since this subchapter was last revised. Section 111.105-47. The Coast Guard would add a new Sec. 111.105- 47, Duct keel ventilation or lighting, to reflect international practice by citing recognized classification society rules for ventilation, lighting and gas detection in special areas such as pipe tunnels, double bottoms and duct keels. Subpart 111.107. The Coast Guard would revise subpart 111.107, Industrial Systems, to define the subject term. The proposed definition would expand the applicability of industrial systems to vessel types other than Mobile Offshore Drilling Units. Additionally, the Coast Guard proposes the general safety requirements of Secs. 111.12-1(b) and 111.12-1(c) for generator prime movers be applied to industrial system prime movers. Part 112--Emergency Lighting and Power Systems Section 112.05-1. The Coast Guard would revise paragraph (a) in Sec. 112.05-1, Purpose, to remove ambiguity with regard to the purpose and intent of ensuring a dependable, independent and dedicated emergency power source. The Coast Guard would add a new paragraph (c) to allow the Commanding Officer, Marine Safety Center, to authorize certain electrical loads be connected to the emergency power source. These include loads that may be required in an emergency due to the particular mission or configuration of the vessel. When these additional loads are connected to the emergency power source, the emergency power source must be sized to handle these loads using a unity (1.0) service factor or an automatic load shedding scheme which removes these loads before overloading the emergency source of power. Section 112.05-5. The Coast Guard would revise paragraph (a) of Sec ar mission or configuration of the vessel. When these additional loads are connected to the emergency power source, the emergency power source must be sized to handle these loads using a unity (1.0) service factor or an automatic load shedding scheme which removes these loads before overloading the emergency source of power. Section 112.05-5. The Coast Guard would revise paragraph (a) of Sec. 112.05-5, Emergency power source, to reference possible additional loads allowed by the Commanding Officer, Marine Safety Center in accordance with the proposed addition of Sec. 112.05-1(c) above. The Coast Guard would revise note 1 of Table 112.05-5(a) to be consistent with ABS rule 4/5.40.4. The Coast Guard would revise paragraph (c), which addresses the requirements for emergency power installations, to incorporate a reference to subchapter S (Stability). This would require a vessel's emergency power installation to function at specific angles of heel and trim, depending on the vessel type. The Coast Guard would revise paragraph (d), which addresses the requirements for the emergency power source, by adding associated transforming equipment and the emergency switchboard to the list of equipment required to be located aft of the collision bulkhead, outside the machinery space, and above the uppermost continuous deck. The Coast Guard interprets SOLAS 74 as requiring the ``emergency source of power'' to include the power source, any associated transforming equipment, and the emergency switchboard. This proposed change also prohibits any other equipment from being located in the same space as the emergency power source and its associated equipment. The Coast Guard would revise paragraph (e) to conform with the requirements imposed by SOLAS 74 II-1/43-1.3. Section 112.15-1. The Coast Guard would revise paragraphs (c), (g), ssociated transforming equipment, and the emergency switchboard. This proposed change also prohibits any other equipment from being located in the same space as the emergency power source and its associated equipment. The Coast Guard would revise paragraph (e) to conform with the requirements imposed by SOLAS 74 II-1/43-1.3. Section 112.15-1. The Coast Guard would revise paragraphs (c), (g), (j), and (k) of Sec. 112.15-1, Temporary emergency loads, to incorporate the semantics used in SOLAS 74. Paragraph (p) would be revised to include gas detection systems. New paragraph (q) would be added to include lighting for helicopter operations, if installed. New paragraph (r) would be added to include general emergency alarm power, reflecting SOLAS 74 requirements in Regulation III/50. Section 112.15-5. The Coast Guard would revise paragraph (b) in Sec. 112.15-5, Final emergency loads, to identify the circuits of a passenger elevator that must be powered from the final emergency power source regardless of the type of vessel. The Coast Guard would also revise paragraph (f) to require electrically-driven sprinkler systems, water-spray extinguishing systems, and the foam system pump to be powered from the final emergency source of power, paragraph (g) to include a geared diesel's lube oil pump which was unintentionally omitted at the last revision of this section, and paragraph (i) to specifically mention new Global Marine Distress Safety System installations (GMDSS). The Coast Guard would combine paragraphs (j), ter-spray extinguishing systems, and the foam system pump to be powered from the final emergency source of power, paragraph (g) to include a geared diesel's lube oil pump which was unintentionally omitted at the last revision of this section, and paragraph (i) to specifically mention new Global Marine Distress Safety System installations (GMDSS). The Coast Guard would combine paragraphs (j), (k), (l), (m), and (n) into a single paragraph concerning navigation aids, all of which are either required or recommended by international practice. This change will allow a degree of latitude in eliminating unnecessary navigation equipment from that required to be powered from the final emergency power source. As a result of this change, paragraphs (o), steering gear feeders, (p), general alarm, (q), blow- out preventer, (r), diving systems, (s), emergency generator starting air compressor, and (t), steering gear failure alarm, of this section would be re-lettered as paragraphs (k), (l), (m), (n), (o), and (p). The Coast Guard would add paragraphs (q), (r), (s), (t), (u), and (v) to require that the following be powered from the final emergency source: the ballast control systems on column-stabilized MODUs, the automation loads required by part 62 of this chapter, motor-operated valves for cargo and fuel oil systems if the emergency source of power is their source of power to meet Sec. 56.50-60(d), stabilizer wing positioning motors and indicators and smoke extraction fans and CO2 exhaust fans. Section 112.39-1 and 112.39-3. The Coast Guard would eliminate paragraph (a)(4) of Sec. 112.39-1, General, as Sec. 112.39-3, Operations, sufficiently defines the performance requirements of the lanterns. The Coast Guard would revise paragraph (a) of Sec. 112.39-3, Operation, to conform with SOLAS 74 Regulation II-1/42-1. Section 112.43-1. The Coast Guard would revise paragraph (b) of Sec. 112.43-1, Switches, to change a reference from a deleted section to an active section Sec. 112.39-1, General, as Sec. 112.39-3, Operations, sufficiently defines the performance requirements of the lanterns. The Coast Guard would revise paragraph (a) of Sec. 112.39-3, Operation, to conform with SOLAS 74 Regulation II-1/42-1. Section 112.43-1. The Coast Guard would revise paragraph (b) of Sec. 112.43-1, Switches, to change a reference from a deleted section to an active section. Sections 112.43-3 and 112.43-7. The Coast Guard would delete Sec. 112.43-3, Controls; general, and rename Sec. 112.43-7, Navigating bridge distribution panel. The Coast Guard would revise certain entries in paragraph (a) to make terminology consistent with SOLAS 74. The present Sec. 112.43-3 repeats the requirements of Sec. 112.43-7. Section 112.43-5. The Coast Guard would revise Sec. 112.43-5, Controls on island type vessels, to replace the terms ``lifeboat'' and ``liferaft'' with the term ``survival craft'' to agree with SOLAS 74. Section 112.43-11. The Coast Guard would revise Sec. 112.43-11, Illumination for launching operations, to replace the terms ``lifeboat'' and ``liferaft'' with the term ``survival craft'' to agree with SOLAS 74. Section 112.43-15. The Coast Guard would revise Sec. 112.43-15, Emergency lighting feeders, to replace the term ``firescreen'' with the term ``fire'' to agree with SOLAS 74. Section 112.43-17. The Coast Guard would delete Sec. 112.43-17, Emergency light markers. The requirement that all emergency lights be individually marked is overly restrictive and does not provide a significant safety feature. Section 112.45-5. The Coast Guard would relocate the requirements of Sec. 112.45-5, Test switch, to subpart 111.30, Switchboards. This proposed change would consolidate the requirements for equipment required to be on the emergency switchboard in one section. Section 112.50-1. The Coast Guard would combine paragraphs (d) and rly restrictive and does not provide a significant safety feature. Section 112.45-5. The Coast Guard would relocate the requirements of Sec. 112.45-5, Test switch, to subpart 111.30, Switchboards. This proposed change would consolidate the requirements for equipment required to be on the emergency switchboard in one section. Section 112.50-1. The Coast Guard would combine paragraphs (d) and (e) in Sec. 112.50-1, General, to clarify that diesel or gas turbine engines used to power emergency generators must not have any starting aids, except a thermostatically-controlled electric water-jacket heater connected to the final emergency bus. Additionally, the time for the emergency generator to be capable of carrying its full load is increased from 20 to 45 seconds to agree with SOLAS 74. Sections 112.50-1, 112.50-3, 112.50-5, and 112.50-7. The Coast Guard would add new paragraph (k) of Sec. 112.50-1 to include requirements for starting devices on emergency generating sets. SOLAS 74, Regulation II-1/44, requires that ``Each emergency generating set arranged to automatically start shall be equipped with starting devices approved by the administration with a stored energy capability of at least three consecutive starts. A second source of energy shall be provided for an additional three starts within 30 minutes unless manual starting can be demonstrated to be effective.'' The proposed change parallels the International Association of Classification Societies (IACS) interpretation and affects Sec. 112.50-3, Hydraulic starting; Sec. 112.50-5, Electric starting; and Sec. 112.50-7, Compressed air starting which are therefore being revised. Section 112.55-15. The Coast Guard would revise Sec. 112.55-15, Capacity of storage batteries, to reflect the requirements of SOLAS 74 regarding opening and closing of watertight doors. This is similar to the change proposed to subpart 111.97, Electric Power-Operated Watertight Door Systems, which addresses hydraulic opening and closing of watertight doors. which are therefore being revised. Section 112.55-15. The Coast Guard would revise Sec. 112.55-15, Capacity of storage batteries, to reflect the requirements of SOLAS 74 regarding opening and closing of watertight doors. This is similar to the change proposed to subpart 111.97, Electric Power-Operated Watertight Door Systems, which addresses hydraulic opening and closing of watertight doors. Part 113--Communication and Alarm Systems and Equipment Subpart 113.10. The Coast Guard would revise the title of subpart 113.10, Fire Detecting and Alarm Systems and Manual Fire Alarm Systems, to include smoke detecting systems. Section 113.10-7. The Coast Guard would revise Sec. 113.10-7, Connection boxes, to introduce alternative methods of compliance by referencing standards of construction of the IEC. Section 113.10.9. The Coast Guard would revise paragraph (a) of Sec. 113.10-9, Power supply, to align fire detection system equipment requirements according to international practice, and remove paragraph (c). Section 113.20-3. The Coast Guard would change the title of Sec. 113.20-3, Watertight equipment, to a more general term, Connection boxes, to introduce alternative methods of compliance by referencing the construction standards of the IEC. Section 113.25-6. The Coast Guard would revise paragraphs (d) and (e) of Sec. 113.25-6, Power supply. In view of technological advances in electronic simulation and our acceptance of IEC voltages, the 6-120 volt requirement is unnecessarily restrictive. Additionally, since SOLAS 74 Regulation III/50 requires the general emergency alarm to be powered from the main and emergency source, the Coast Guard proposes to refer to that regulation in this paragraph instead. Paragraph (e) would contain wording to retain battery, temporary emergency bus and communication switchboard options. Section 113.25-8. The Coast Guard would revise paragraphs (b), (c), onally, since SOLAS 74 Regulation III/50 requires the general emergency alarm to be powered from the main and emergency source, the Coast Guard proposes to refer to that regulation in this paragraph instead. Paragraph (e) would contain wording to retain battery, temporary emergency bus and communication switchboard options. Section 113.25-8. The Coast Guard would revise paragraphs (b), (c), (f) and (g) in Sec. 113.25-8, Distribution of general alarm system feeders and branch circuits, to remove the restriction of having only five general alarm bells on a branch circuit. The existing regulation used an arbitrary number to ensure that the branch circuit was not overloaded. The specific reference to fuses will be replaced by a general statement regarding overcurrent protection. The remaining requirements ensure that a circuit is not compromised by a fault in another part of the vessel. Additionally, the size of vertical zones, mentioned in paragraph (g), is changed to meet the accepted main vertical fire zone dimension. Section 113.25-9. The Coast Guard would revise paragraph (b) of Sec. 113.25-9, Location of general alarm bells, to remove the detailed acoustic specifications. These specifications are replaced with more general performance requirements in proposed new paragraph (c). Section 113.25-10. The Coast Guard would revise Sec. 113.25-10, Location of flashing red lights, to include existing policy that only general alarm beacons, used in high noise areas, be red. This is required so that personnel are not confused by the use of the same visual signal to indicate a number of conditions. Section 113.25-11. The Coast Guard would revise Sec. 113.25-11, Contact makers, to remove the detailed construction requirements for the general alarm contact maker. The performance requirements for this component remain in effect. Section 113.25-12. The Coast Guard would revise Sec ed so that personnel are not confused by the use of the same visual signal to indicate a number of conditions. Section 113.25-11. The Coast Guard would revise Sec. 113.25-11, Contact makers, to remove the detailed construction requirements for the general alarm contact maker. The performance requirements for this component remain in effect. Section 113.25-12. The Coast Guard would revise Sec. 113.25-12, Vibrating bells, to allow the use of electronic devices to simulate the sound produced by a vibrating bell. Section 113.25-16. The Coast Guard would revise Sec. 113.25-16, Fuses, to have this regulation apply to circuit breakers and fuses, both of which are allowable overcurrent devices. Subpart 113.30. The Coast Guard would revise subpart 113.30, Sound Powered Telephone and Voice Tube Systems. Voice tubes will be eliminated and, owing to today's technology, the Coast Guard will allow for choices by recognizing systems of communications other than sound powered phones that are accepted by recognized classification society rules. Section 113.30-1. The Coast Guard would revise Sec. 113.30-1, Applicability, to require self-propelled Mobile Offshore Drilling Units meet the same requirements as other self-propelled vessels. Section 113.30-5. The Coast Guard would revise paragraphs (a), (d), (g), (h), and (i) of Sec. 113.30-5, Requirements, to generalize communication systems and to incorporate the necessary clarifications pertinent to Mobile Offshore Drilling Unit applications. The Coast Guard would add new paragraph (j) to the list of locations where common means of voice communication and calling are required. This requirement increases the level of safety aboard the vessel and is consistent with the requirements of SOLAS 74. Section 113.30-20. The Coast Guard would revise paragraphs (a), ry clarifications pertinent to Mobile Offshore Drilling Unit applications. The Coast Guard would add new paragraph (j) to the list of locations where common means of voice communication and calling are required. This requirement increases the level of safety aboard the vessel and is consistent with the requirements of SOLAS 74. Section 113.30-20. The Coast Guard would revise paragraphs (a), (b), and (d) (paragraph (d) will be relettered as (c)) of Sec. 113.30- 20, Sound-powered telephone systems: General requirements, to correct the semantics of referencing ``communications systems'' versus only ``sound-powered phones''. Section 113.30-25. The Coast Guard would revise paragraph (a) of Sec. 113.30-25, Sound-powered telephone system; detailed requirements, to remove the requirement that sound-powered telephones be approved by the Commandant. The remaining regulations are sufficient to ensure proper installation and operation of sound-powered telephones, or other reliable means of voice communications and calling. Section 113.35-3. The Coast Guard would revise paragraph (e)(3) of Sec. 113.35-3, General requirements, to reflect the above change in interior communications terminology. Sections 113.35-5 and 113.35-7. The Coast Guard would revise Sec. 113.35-5, Electric engine order telegraph systems; general requirements, and Sec. 113.35-7, Electric engine order telegraph systems; detailed requirements, to eliminate the detailed design specifications for electric engine-order telegraph systems. These two sections are combined under Sec. 113.35-5 to produce a single section addressing performance requirements. Sections 113.35-9 and 113.35-11. The Coast Guard would revise Sec. 113.35-9, Mechanical engine order telegraph systems; general requirements, and Sec. 113.35-11, Mechanical engine order telegraph systems; detailed requirements, to eliminate the detailed design specification for mechanical tions are combined under Sec. 113.35-5 to produce a single section addressing performance requirements. Sections 113.35-9 and 113.35-11. The Coast Guard would revise Sec. 113.35-9, Mechanical engine order telegraph systems; general requirements, and Sec. 113.35-11, Mechanical engine order telegraph systems; detailed requirements, to eliminate the detailed design specification for mechanical engine-order telegraph systems. These two sections are combined under Sec. 113.35-9 to produce a single section addressing performance requirements. Section 113.37-5. The Coast Guard would correct semantics concerning ``navigating bridge'' versus ``wheelhouse'' in Sec. 113.37- 5, General requirements. Section 113.37-10. The Coast Guard would remove paragraphs (b), (c), and (d) in Sec. 113.37-10, Detailed requirements. Most of these requirements represent standard marine practice, thereby making regulation unnecessary. New paragraph (b) would restate present paragraph (c)'s watertight requirement with international standard option. Section 113.40-10. The Coast Guard would revise Sec. 113.40-10, Detailed requirements, to add clarifying language that rudder-angle indicator circuits must be separate and independent from the autopilot and the dynamic positioning system as well as the steering gear control system. The Coast Guard would also remove paragraphs (b), (c), (d), (e), and (f) in this section. Most of these requirements represent standard marine practice, thereby making regulation unnecessary. New paragraph (b) would restate present paragraph (e)'s watertight requirement with international standard options. Sections 113.43-3 and 113.43-5. The Coast Guard would revise paragraph (a) of Sec. 113.43-3, Alarm system, and (b) of Sec. 113.43-5, Power supply, by substituting ``navigating bridge'' for ``pilothouse'' or ``wheelhouse''. Subpart 113.50 thereby making regulation unnecessary. New paragraph (b) would restate present paragraph (e)'s watertight requirement with international standard options. Sections 113.43-3 and 113.43-5. The Coast Guard would revise paragraph (a) of Sec. 113.43-3, Alarm system, and (b) of Sec. 113.43-5, Power supply, by substituting ``navigating bridge'' for ``pilothouse'' or ``wheelhouse''. Subpart 113.50. The Coast Guard would revise and rename subpart 113.50, Emergency Loudspeaker Systems, to read, Public Address Systems, in order to incorporate performance requirements which are now in subchapter Q, subpart 161.004. The Coast Guard would eliminate subchapter Q, subpart 161.004. These proposals are consistent with SOLAS 74 III/6.4. Subpart 113.65. The Coast Guard would revise subpart 113.65, Whistle Operators, to correct the reference to IEEE Standard 45. Subpart 113.70. The Coast Guard would eliminate subpart 113.70, Smoke Detector Systems. This equipment is now included with Fire Detecting Systems in the proposed revision to Sec. 113.10. Part 161--Electrical Equipment Subpart 161.002. The Coast Guard would extensively revise subpart 161.002, Fire-Protective Systems, in order to eliminate overly restrictive construction requirements and to provide for options in the manufacture and testing of fire and smoke detecting and alarm systems via internationally accepted standards.

Regulatory Evaluation This proposal is not a significant regulatory action under section 3(f) of Executive Order 12866 and does not require an assessment of potential costs and benefits under section 6(a)(3) of that order. It has not been reviewed by the Office of Management and Budget under that order. It is not significant under the regulatory policies and procedures of the Department of Transportation (DOT) (44 FR 11040, February 26, 1979). The Coast Guard expects the economic impact of this proposal to be so minimal that a full Regulatory Evaluation under paragraph 10e of the regulatory policies and procedures of DOT is unnecessary. The Coast Guard has found that most of the changes to the Electrical Engineering Regulations are either editorial or they update technical specifications to reflect the latest practices. There are some regulatory changes that will require different construction. Although some of these changes will cause minor cost increases for shipbuilders, others will result in substantial savings. Many of the proposed rulemaking changes causing cost increases are already current marine industry practice her editorial or they update technical specifications to reflect the latest practices. There are some regulatory changes that will require different construction. Although some of these changes will cause minor cost increases for shipbuilders, others will result in substantial savings. Many of the proposed rulemaking changes causing cost increases are already current marine industry practice. The remaining changes causing cost increases are more than offset by the cost savings offered by several relaxations in the regulations. Overall, it is anticipated that there will be a net cost reduction offered for vessels constructed under these rules, but the exact impact is difficult to determine accurately since it may vary from vessel to vessel. For certain vessels, new requirements may increase costs, but the application of national and international industry consensus standards should enhance performance and thus increase the level of safety. Additionally, due to cost decreases that may result from the removal of the requirements for armor on cable, allowance of the use of NEC and IEC motors, and a variety of circuit breakers conforming to international standards in panelboards, it may be possible to significantly lower costs for each vessel. Actual savings will depend upon the industry practices followed by each vessel designer/shipyard before and after the effective date of these regulations. In addition to the savings in material costs, there are several intangible benefits. Due to the increased reference to national and international standards other than the National Electrical Code and Underwriters Laboratories Inc., certain equipment items will now be more readily available ``off the shelf'' for marine use. The proposed regulations will reduce the regulatory burden on the marine industry, purge obsolete and out-of-date regulations, and eliminate requirements that create an unwarranted differential between domestic rules and international standards onal Electrical Code and Underwriters Laboratories Inc., certain equipment items will now be more readily available ``off the shelf'' for marine use. The proposed regulations will reduce the regulatory burden on the marine industry, purge obsolete and out-of-date regulations, and eliminate requirements that create an unwarranted differential between domestic rules and international standards. The Coast Guard expects that significant economic savings will result from the ability of equipment manufacturers, in many cases, to meet performance specifications instead of design standards and the elimination of the need to submit to the U.S. Coast Guard detailed plans and specifications for approval for equipment such as sound powered telephones, emergency loudspeaker systems, and navigation lights. The Coast Guard solicits cost data and comments regarding the economic impact of these proposed requirements from all interested parties. Small Entities Under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.), the Coast Guard must consider whether this proposal, if adopted, will have a significant economic impact on a substantial number of small entities. ``Small Entities'' may include (1) small businesses and not- for-profit organizations that are independently owned and operated and are not dominant in their fields and (2) governmental jurisdictions with populations of less than 50,000. The Coast Guard believes it has addressed the concerns of many small ed, will have a significant economic impact on a substantial number of small entities. ``Small Entities'' may include (1) small businesses and not- for-profit organizations that are independently owned and operated and are not dominant in their fields and (2) governmental jurisdictions with populations of less than 50,000. The Coast Guard believes it has addressed the concerns of many small entities by the adoption of wide variety of national and international standards regarding system arrangement. Additionally, the proposed regulations will dramatically revise certain prescriptive electrical equipment design, specification, and approval requirements, and replace them with performance-based requirements that incorporate international standards. Whenever possible, requirements have been adjusted to the size of the vessel and in some cases a relaxation of requirements for smaller vessels has been offered. Due to the flexibility of requirements in these proposed rules and the eliminating of regulatory burden, small entities involved in the building or ownership of vessels should experience increasing business opportunities. Collection of Information Under the Paperwork Reduction Act (44 U.S.C. 3501 et. seq.), the Office of Management and Budget (OMB) reviews each proposed rule which contains a collection-of-information requirement to determine whether the practical value of this information is worth the burden imposed by its collection. Collection-of-information requirements include reporting, recordkeeping, notification, and other, similar requirements. This proposed rule contains collection-of-information requirements in the following subparts: subpart 110.25 in subchapter J and subparts 161.002 and 161.010 in subchapter Q. The following particulars apply to subpart 110.25: DOT No.: 2115. OMB Control No.: 2115-0115. Administration: U.S. Coast Guard. Title: Electrical Engineering Regulations--Subchapter J and other, similar requirements. This proposed rule contains collection-of-information requirements in the following subparts: subpart 110.25 in subchapter J and subparts 161.002 and 161.010 in subchapter Q. The following particulars apply to subpart 110.25: DOT No.: 2115. OMB Control No.: 2115-0115. Administration: U.S. Coast Guard. Title: Electrical Engineering Regulations--Subchapter J. Need for Information: This proposed rule would require amendments to the regulations, clarify the regulations, bring them up to date, and delete unnecessary requirements. The revisions to subchapter J will reduce the reliance on domestic standards and will adopt SOLAS 74 and other international standards developed through consensus by the international maritime community. Proposed Sec. 110.25-1 would require industry to complete electrical engineering plans to meet performance requirements on new- built vessels and modifications of current vessels. These requirements will help resolve much of the confusion during inspections which has risen due to the complexity of electrical system arrangements on modern merchant vessels. Proposed Use of Information: The reporting of this information is necessary to ensure compliance with electrical engineering safety regulations. Through the review of the design plans prior to construction, the vessel owner or builder may be assured that the vessel, if built in accordance with the plans, will meet regulatory standards. Frequency of Response: The various information called for in Sec. 110.25 would be reported on occasion. Design plans will only be submitted when there is construction of new-built vessels or modification of current vessels. Burden Estimate: 478 hours. Respondents: 175 owners or operators. Average Burden Hours per Respondent: 1 hour per submission. The following particulars apply to subparts 161.002 and 161.010: DOT No.: 2115. OMB Control No.: 2115-0121.

Need for Information: This proposed rule world require amendments to the regulations, clarify the regulations, bring them up to date, and delete unnecessary requirements. The revisions to subchapter Q will required industry to maintain records of production tests for some fire protection systems. These plans consist mainly of system/material tests that are necessary to determine that the equipment being used in the construction of a fire protection system meets the minimum performance requirements. The following is a section-by-section justification of the collection requirements. Proposed subpart 161.002 would require manufacturers to complete electrical specifications to meet performance requirements for fire protection systems. This requirement will help identify specific equipment approved and to permit the production of equipment identical to the equipment samples originally tested. Proposed Use of Information: The reporting of this information is necessary to ensure compliance with electrical system arrangement/ equipment and fire protection system regulations. Through the review of approval plans, the manufacturer may be assured that the material or device, if manufactured in accordance with the material specifications, will meet regulatory standards. Frequency of Response: The various information called for in subpart 161.002 would be reported on occasion. Approval for equipment will only be submitted when production tests are required. Burden Estimate: 60 hours. Respondents: 6 manufacturers acturer may be assured that the material or device, if manufactured in accordance with the material specifications, will meet regulatory standards. Frequency of Response: The various information called for in subpart 161.002 would be reported on occasion. Approval for equipment will only be submitted when production tests are required. Burden Estimate: 60 hours. Respondents: 6 manufacturers. Average Burden Hours Per Respondent: 10 hours per respondent. The Coast Guard has submitted the requirements to OMB for review under section 3504(h) of the Paperwork Reduction Act. Persons submitting comments on the requirements should submit their comments both to OMB and to the Coast Guard where indicated under ADDRESSES. Federalism The Coast Guard has analyzed this proposal under the principles and criteria contained in Executive Order 12612 and has determined that this proposal does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment. Environment The Coast Guard has considered the environmental impact of this rule and concluded that, under paragraphs 2.B.2e(34)(d) and (e) of Commandant Instruction M16475.1B, this rule is categorically excluded from further environmental documentation. This rule concerns only system arrangement and equipment approval. The approved system arrangement and equipment required by this rule should contribute in the enhancement of vessel safety, and thereby help to minimize any impact to the marine environment. A ``Categorical Exclusion Determination'' is available in the docket for inspection or copying where indicated under ADDRESSES.
