 AGENCY: Coast Guard, DHS.
 ACTION: Notice of proposed rulemaking.
 SUMMARY: The Coast Guard proposes to amend the current regulations for fire suppression systems on several classes of commercial vessels. The amendments would clarify that approved alternatives to carbon dioxide systems may be used to protect some spaces on these vessels and would set general requirements for alternative systems. Additionally, new and existing carbon dioxide systems, when used in spaces that can be accessed by persons onboard the specified commercial vessels, would need to be equipped with lockout valves and olfactory additives to protect persons in the event of a carbon dioxide discharge. By requiring these features on carbon dioxide systems and by making a wider range of fire suppression systems available, the proposed regulations advance the Coast Guard's mission of promoting maritime safety and mobility.

 III. Background Until recently, carbon dioxide (CO2) systems were the only systems suitable for suppressing or extinguishing fires in certain vessel spaces, such as those used for cargo and various types of machinery. Our current regulations require the use of CO2
                         systems in such spaces on towing vessels, tank vessels, cargo and miscellaneous vessels, mobile offshore drilling units (MODUs), offshore supply vessels, public nautical school ships, and large passenger vessels (“Subchapter H” vessels). We also allow carbon dioxide systems on small passenger vessels carrying more than 150 passengers or with overnight accommodations for more than 49 passengers (“Subchapter K” vessels) and other small passenger vessels (“Subchapter T” vessels). Carbon dioxide systems work by flooding a protected space with CO2, thereby depriving a fire of the oxygen it needs to burn. Unfortunately, when a carbon dioxide discharge occurs, oxygen deprivation poses a risk to persons who may be in this protected space. Crew members have died when odorless CO2
                         gas was discharged in their spaces accidentally or without adequate warning to evacuate. In recent years, alternative systems have been developed that are comparable to carbon dioxide systems in their ability to suppress fires, but that do not pose the same risks to persons onboard. Our regulations currently allow for the use of Coast Guard-approved alternative systems. At present, most approved systems use halocarbon clean agents HFC-227ea (heptafluoropropane), FK-5-1-12 (dodecafluoro-2-methylpentan-3-one), or IG-541 (nitrogen 52%, argon 40%, and carbon dioxide 8%). We have also approved water mist systems for some applications. These systems have been tested by independent testing laboratories and have laboratory listings. Systems using other agents may be developed and approved in the future. Along with the manufacturers of alternative systems, shipyards, and independent testing laboratories, we believe it would promote safety and be advantageous to industry to issue new regulations for installing, maintaining, and using approved carbon dioxide-alternative fire suppression systems. IV. Discussion of Proposed Rule We are proposing two overall changes to our regulations. *1. Lockout valves and olfactory additives.* We propose requiring lockout valves and olfactory additives in any CO2
                         system used in a space that may be occupied by persons onboard, even if only occasionally. Lockout valves, which are already required for shore-based facilities by National Fire Protection Association standards (NFPA 12, 2008 edition), are intended to be used during system maintenance to prevent inadvertent flooding of a protected space. We would require lockout valves on vessels that use CO2
                         systems in spaces containing more than 6,000 cubic feet and in smaller spaces that do not have horizontal escapes, which provide a quick way to evacuate. Odorizer units would be required for CO2
                         systems of any size to provide a scent to normally odorless CO2
                         during discharge. A distinctive-smelling substance, like wintergreen, is added to the CO2
                         so that in the event of a CO2
                         discharge in a vessel's space, any persons in that space can quickly smell the discharge and evacuate. Additionally, the odor would warn persons in adjacent spaces that the CO2
                         may have migrated. The new lockout valve and olfactory additive requirements would apply immediately to new systems. They would be phased-in for existing systems, allowing the necessary simple retrofits to be made during drydocking or routine maintenance, thereby reducing the financial impact on vessel owners. Retrofitting would involve dismantling and reassembling a small section of system piping to include a lockout valve. *2. Alternative systems.* The second overall change we propose is to amend our existing regulations to make it clear that alternative systems using clean agent and inert gases may be used. Furthermore, we are proposing clarifications to the general requirements for maintaining, installing, and using an alternative system. System layout and control requirements would be based on the current regulations for engineered CO2
                         systems on inspected vessels. Independent laboratories would oversee prototype testing and follow-up quality control supervision. The following table lists the parts within 46 CFR that are affected by our proposal and the specific sections we propose to amend. The foregoing discussion provides a general explanation for each of these changes. When additional information is required, it appears in the table in parentheses. The table omits any discussion of numerous minor and nonsubstantive style, format, or wording changes that we are proposing solely to improve the clarity of our regulations.

 V. Incorporation by Reference Material proposed for incorporation by reference appears in 46 CFR 34.01-15, 46 CFR 147.7, and 46 CFR 162.161-2. You may inspect this material at U.S. Coast Guard Headquarters where indicated under 
                        **ADDRESSES**
                        . Copies of the material are available from the sources listed in 46 CFR 34.01-15, 46 CFR 147.7, and 46 CFR 162.161-2. Before publishing a binding rule, we will submit this material to the Director of the Federal Register for approval of the incorporation by reference. VI. Regulatory Analysis We developed this proposed rule after considering numerous statutes and executive orders related to rulemaking. Below we summarize our analyses based on 13 of these statutes or executive orders. A. Regulatory Planning and Review This proposed rule is not a significant regulatory action under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under section 6(a)(3) of that Order. The Office of Management and Budget (OMB) has not reviewed it under that Order. A draft Regulatory Analysis is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. A summary of the preliminary Regulatory Analysis follows. We propose to amend the current regulations for carbon dioxide fire suppression systems on commercial vessels. The amendments would require certain safety requirements for current and future users of CO2
                         systems. The proposed rule would require lockout valves for certain protected spaces as well as for an olfactory additive as a warning measure for all CO2
                         systems. The proposed rule would also clarify what approved alternatives to CO2
                         systems may be used to protect some spaces on these vessels and would set general requirements for alternative systems. We do not expect industry would incur additional costs as a result of the provisions for alternative systems. 
                        *See*
                         below for additional discussion of alternative systems. Carbon dioxide fire suppression systems pose a risk of asphyxiation to personnel. Lockout valves and olfactory additives help protect persons in the event of an inadvertent release during maintenance. Olfactory additives offer additional protection from leaks from a protected space to adjacent spaces and help alert personnel when CO2
                         has been released. By requiring these features on carbon dioxide systems and making a wider range of fire suppression systems available, the proposed amendments would advance the Coast Guard's missions of promoting maritime safety and mobility. U.S. flag vessel owners are expected to incur costs associated with this proposed rule. Vessel owners with existing CO2
                         fire suppression systems would be required to add the lockout valves and olfactory units within five years of the publication of the final rule. This would allow enough time for vessel owners to add these features during scheduled vessel maintenance periods and would reduce the cost of compliance for vessel owners. For purposes of this regulatory assessment, we assume an equal proportion of systems will be retrofitted each year for five years. New vessel owners will incur the costs as systems are incorporated into new ships at construction. Affected Population Vessels with CO2
                         fire suppression systems that are not in compliance with the proposed regulation would be required to install lockout valves at entrances to all spaces greater than 6,000 cubic feet in volume where personnel may enter, as well as, in spaces with 6,000 cubic feet in volume or less that do not have a horizontal escape for quick escape. Vessels equipped with existing CO2
                         fire suppression systems would incur a cost for retrofitting valves to the systems. Newly constructed vessels installing new fire CO2
                         suppression systems in similar spaces would also incur a cost for installation of lockout valves, although at a lower cost than retrofitting systems on existing vessels because installations during vessel construction are typically less costly. Based on Coast Guard Marine Investigation Security and Law Enforcement (MISLE) data, we estimate 
                        ( print page 8435)
                        there are potentially 1,702 existing vessels with a total of 3,204 CO2
                         fire suppression systems that would require lockout valves. The 3,204 existing systems consist of 1,054 larger systems that would require more expensive lockout valves and 2,150 smaller systems that would require less expensive lockout valves. Using MILSE data, we estimate there are potentially 22 small systems and 12 large systems installed each year on new vessels, which would be required to have lockout valves. The population of affected vessels that would need to install olfactory additives (odorizers) includes all existing and new vessels with CO2
                         systems. All existing vessels with CO2
                         systems would require a retrofit for each protected space. Based on MISLE data, we estimate there are potentially 7,815 systems on 3,567 vessels that would be required to install odorizers.[1]
                        
                         Each new vessel with CO2
                         systems would also require an odorizer for compartments of all sizes. Of the new vessels constructed annually, we estimate the 46 new systems/year installed would require odorizers. Costs Based on industry data, we estimate that average 2008 industry prices for installed retrofit large and small lockout valves are $3,513 and $1,475, respectively. Systems that handle more than 2,450 pounds of CO2
                         require a valve larger than 2 inches. Of the 3,204 existing systems affected by this proposed rule, 1,054 would require the larger, more expensive lockout valves, while 2,150 systems require the smaller valves for a total undiscounted cost of about $6,873,425. The annual undiscounted cost for owners of vessels with existing systems to meet the lockout valve requirement of this proposed rule would be approximately $1,374,685 for each year of the five-year phase-in period. Vessel owners wishing to install a new CO2
                         fire suppression system would be required to have the lockout valves included in the installation. We estimate that the annual undiscounted industry cost for adding lockout valves to new CO2
                         fire suppression systems to be $65,932 per year (based on installed costs on new systems of $1,258 for small valves and $3,188 for large valves). Industry would incur this cost for each year over the ten-year period of analysis. As for odorizers, we estimate that the retrofit installed costs, including three warning signs, are $551/unit based on industry information. This is about $35 more than the estimated cost for new odorizers installed. With a five-year phase-in for all 7,815 systems, 1,563 systems will be retrofitted on average each year. We estimate the total annual undiscounted cost of the retrofit will be $861,213. For new systems using the lockout valve, we estimate the total annual undiscounted cost to be about $17,558 for all 34 protected areas. For the remaining systems not required to have a lockout valve, the cost for installing odorizers in 12 areas will be about $6,197. The total cost per vessel would be dependent on the number of areas protected by CO2. We estimated the total cost of this rulemaking over a ten-year period to be $12.1 million (
                        *see*
                         Table 2). For the first five years, we estimated the undiscounted costs to be $2,325,584/year for both retrofits and new installations. Table 2—Total Cost of Adding Lockout Valves and Odorizers to CO2

                             Totals may not add due to rounding.
 For the remaining years, the undiscounted costs are $89,686/year due to the new installations only. We discounted the annual costs at 3 percent and 7 percent and also annualized the total costs at the same rates. The total 10-year cost of the proposed rule is $9.8 million at a 7 percent discount rate and $11 million at 3 percent. This proposed regulation would clarify Coast Guard acceptance of alternatives to using CO2
                         systems. We do not believe that these provisions would have a cost impact because the Coast Guard has been approving alternative systems on an ad hoc basis. We believe these approved installed alternative systems would be compliant with the requirements for alternative systems proposed in this rulemaking. With regard to alternative fire suppression systems, the use of halocarbon (only one of a number of alternatives) fire suppression systems has been increasing in recent years (2006-2008). Our records indicate that industry installed an average of 21 halocarbon fire suppression systems compared to an average of 34 CO2
                         fire suppression systems with capacity over 6,000 cubic feet during this period. Benefits The primary benefit associated with this proposed rule is the reduction in risk of injuries and fatalities related to CO2
                         exposure. CO2
                         exposure has long been recognized as a potential hazard to human health. The National Institute of Occupational Safety and Health (NIOSH), in its publication NIOSH 76-194, “Criteria for a Recommended 
                        ( print page 8436)
                        Standard—Occupational Exposure to Carbon Dioxide,” available at 
                        *http://www.cdc.gov/​niosh/​76-194.html,*
                         has set criteria for a standard for limits of exposure to CO2
                         in workplace settings. Other Federal and industry agencies and associations have also recently concluded that CO2
                         fire suppression systems could pose a risk. For example, the National Fire Prevention Association (NFPA) guidance in its 2005 Edition for CO2
                         fire suppression systems located on land states that “total flooding CO2
                         suppression systems shall not be used in normally occupied enclosures”. In addition, the EPA, in its 2000 report, “Carbon Dioxide as a Fire Suppressant: Examining the Risk,” has suggested that clarifying maritime regulation would be beneficial to reducing accidental exposure. The Regulatory Analysis available in the docket has additional detail on the assessment of the benefits and costs of this rulemaking. The assessment also contains details and analysis of the alternatives considered for this rulemaking. B. Small Entities Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have considered whether this proposed rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated as well as not being dominant in their fields, and governmental jurisdictions with populations of less than 50,000. A combined Regulatory Assessment and Initial Regulatory Flexibility Analysis discussing the impact of this proposed rule on small entities is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. Our data shows that there are 489 known entities that owned vessels with CO2
                         fire suppression systems onboard in 2008. Of the 489, 26 are government entities with populations of more than 50,000 that we excluded from the small business analysis. Of the remaining 463 entities, we were able to find revenue and employment information for 100 entities. Of the 100, we confirmed that 37 were small as defined by Small Business Administration (SBA) size standards. We assumed the remaining 363 entities to be small because we were unable to find revenue or employment information. Given that assumption of size, we concluded that small entities likely comprise 400 (363 + 37) or 81.8% of the total affected population. Of the small entities with revenue and employee size data, we determined that 83.8% would have an annual revenue impact of less than 1 percent. Further, we estimated that the impact on 97.3% of these small entities would be less than 3% of annual revenue. Therefore, the Coast Guard certifies under 5 U.S.C. § 605(b) that this rulemaking would not have a significant economic impact on a substantial number of small entities. We are interested in the potential impacts from this proposed rule on small businesses and we request public comment on these potential impacts. If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this rulemaking would have a significant economic impact on it, please submit a comment to the Docket Management Facility at the address under the “Public Participation and Request for Comments” section of this preamble. In your comment, explain why, how, and to what degree you think this rule would have an economic impact on you. C. Assistance for Small Entities Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we want to assist small entities in understanding the proposed rule so that they can better evaluate its effects on them and participate in the rulemaking. If the rule affects your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance, please call Lieutenant Commander Suzanne Hemann, CG-5214, U.S. Coast Guard, telephone 202-372-1356 or send her an e-mail at 
                        *suzanne.e.hemann@uscg.mil.*
                         The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard. Small businesses may send comments on the actions of Federal employees who enforce, or otherwise determine compliance with, Federal regulations to the Small Business and Agriculture Regulatory Enforcement Ombudsman and the Regional Small Business Regulatory Fairness Boards. The Ombudsman evaluates these actions annually and rates each agency's responsiveness to small business. If you wish to comment on actions by employees of the Coast Guard, call 1-888-REG-FAIR (1-888-734-3247). D. Collection of Information This proposed rule would require no new collection of information (COI) under the Paperwork Reduction Act (44 U.S.C. 3501-3520). The U.S. Coast Guard has been approving alternatives to CO2
                         systems for a number of years and accounting for it in COI document “OMB Control Number 1625-0035”. This rulemaking would not require any new recordkeeping or reporting requirements. Satisfactory lockout valve and olfactory installation will be confirmed by normal future Coast Guard inspections. E. Federalism A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on State or local governments and would either preempt State law or impose a substantial direct cost of compliance on them. We have analyzed this proposed rule under that Order and have determined that it does not have implications for federalism. F. Unfunded Mandates Reform Act The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 or more in any one year. Though this proposed rule would not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble. G. Taking of Private Property This proposed rule would not affect a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights. H. Civil Justice Reform This proposed rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden. I. Protection of Children We have analyzed this proposed rule under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This rule is not an economically significant rule and would not create an environmental risk to health or risk to 
                        ( print page 8437)
                        safety that might disproportionately affect children. J. Indian Tribal Governments This proposed rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it would not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes. K. Energy Effects We have analyzed this proposed rule under Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use. We have determined that it is not a “significant energy action” under that order because it is not a “significant regulatory action” under Executive Order 12866 and is not likely to have a significant adverse effect on the supply, distribution, or use of energy. The Administrator of the Office of Information and Regulatory Affairs has not designated it as a significant energy action. Therefore, it does not require a Statement of Energy Effects under Executive Order 13211. L. Technical Standards The National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note) directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through the Office of Management and Budget, with an explanation of why using these standards would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (
                        *e.g.*
                         specifications of materials, performance, design, or operation; test methods; sampling procedures; and related management systems practices) that are developed or adopted by voluntary consensus standard bodies. This proposed rule uses the following consensus standards: Underwriters Laboratories (UL) standards UL 2127 entitled “Standard for Inert Gas Clean Agent Extinguishing System Units,” UL 2166 entitled “Standard for Halocarbon Clean Agent Extinguishing System Units,” and National Fire Protection Association (NFPA) 2001 entitled “Standard on Clean Agent Fire Extinguishing Systems.” The proposed sections that reference these standards and the locations where these standards are available are listed in the proposed regulatory text for 46 CFR 34.01-15, 147.7, and 162.161-2. This proposed rule also uses technical standards other than voluntary consensus standards. The test described in the regulatory text proposed for 46 CFR 162.161-6 is in accordance with requirements of the International Maritime Organization, IMO MSC/Circ.848 entitled “Revised Guidelines for the Approval of Equivalent Fixed Gas Fire-Extinguishing Systems, as referred to in chapter II-2 of SOLAS 74, for machinery spaces and cargo pump-rooms” and IMO MSC.1/Circ. 1267 entitled “Amendments to the Revised Guidelines for the Approval of Equivalent Fixed Gas Fire-Extinguishing Systems, as referred to in chapter II-2 of SOLAS 74, for machinery spaces and cargo pump-rooms (MSC/Circ. 848)”. The remaining requirements and tests were developed by the Coast Guard and used to evaluate currently-approved carbon dioxide-alternative fire suppression systems. These requirements are described throughout the proposed regulations. They are used because we did not find voluntary consensus standards that are applicable to this rule. If you disagree with our analysis of the voluntary consensus standards listed above or are aware of voluntary consensus standards that might apply, but are not listed, please send a comment to the docket using one of the methods under 
                        **ADDRESSES**
                        . In your comment, please explain why you disagree with our analysis and/or identify voluntary consensus standards we have not listed that might apply. M. Environment We have analyzed this proposed rule under Department of Homeland Security Management Directive 023-01 and Commandant Instruction M16475.lD, which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have made a preliminary determination that this action is one of a category of actions which do not individually or cumulatively have a significant effect on the human environment. A preliminary environmental analysis checklist supporting this determination is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. This rule involves amending the current regulations for carbon dioxide fire suppression systems on several classes of commercial vessels. Exclusion under paragraphs (34)(d) of Figure 2.1 of the Instruction and section 6(a) of the 
                        **Federal Register,**
                         Vol. 67, No. 141, Tuesday July 23, 2002, page 48243 apply because this rule pertains to regulations concerning the equipping of vessels, as well as equipment approval. We seek any comments or information that may lead to the discovery of a significant environmental impact from this proposed rule. List of Subjects 46 CFR Part 25 Fire prevention

                             The difference in the vessel populations and system counts (lockout valve vs. odorizers) is reflective of the large number of extremely small sized systems that need odorizers, but do not need lockout valves (the balance of 7,815−3,204 or 4,611). Back to Citation
