2012-12334. Carbon Dioxide Fire Suppression Systems on Commercial Vessels  

  • Start Preamble Start Printed Page 33860

    AGENCY:

    Coast Guard, DHS.

    ACTION:

    Final rule.

    SUMMARY:

    The Coast Guard is amending the current regulations for fire suppression systems on several classes of commercial vessels. The amendments clarify that approved alternatives to carbon dioxide systems may be used to protect some spaces on these vessels, and set general requirements for alternative systems. Additionally, certain new carbon dioxide systems must be equipped with lockout valves and odorizing units to protect persons after a carbon dioxide discharge. By requiring these features on carbon dioxide systems and by making a wider range of fire suppression systems available, the regulations advance the Coast Guard's strategic goals of promoting marine safety and maritime mobility.

    DATES:

    This final rule is effective July 9, 2012. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register on July 9, 2012.

    II. Regulatory History

    On February 24, 2010, we published a notice of proposed rulemaking entitled “Carbon Dioxide Fire Suppression Systems on Commercial Vessels” in the Federal Register (75 FR 8432). We received 18 comments on the proposed rule. No public meeting was held.

    III. Basis and Purpose

    The basis of this final rule is the Secretary of Homeland Security's regulatory authority under the following statutes. In all cases, the Secretary has delegated this authority to the Coast Guard through Delegation No. 0170.1(92). Section 3306 of Title 46, United States Code (U.S.C.) mandates the issuance of vessel equipment regulations for Coast Guard-inspected vessels and the issuance of structural fire protection regulations for small passenger vessels; 46 U.S.C. 3703 mandates regulations, including fire protection regulations, for vessels carrying liquid bulk dangerous cargoes; 46 U.S.C. 4102 authorizes regulations, after consultation with the Towing Safety Advisory Committee (TSAC), for fire protection and suppression measures on towing vessels; 46 U.S.C. 4302 authorizes safety equipment regulations for recreational vessels; and 46 U.S.C. 4502 mandates fire extinguisher regulations for some uninspected commercial fishing vessels and authorizes safety equipment regulations for certain other uninspected commercial fishing vessels.

    The purpose of this final rule is to advance the Coast Guard's strategic goals of marine safety and maritime mobility, by clarifying and codifying the requirements for fire suppression systems that use carbon dioxide (CO2) alternatives, and by requiring lockout valves and odorizers to improve safety on certain vessels that use carbon dioxide fire suppression systems.

    IV. Background

    This discussion is adapted from Parts III and IV of our NPRM. See 75 FR 8432, 8433.

    Carbon dioxide (CO2) systems are suitable for suppressing or extinguishing fires in certain vessel spaces. They work by flooding spaces with CO2. CO2 flooding deprives a fire of the oxygen it needs to burn, but these same systems have also killed people on U.S. military vessels and foreign flag vessels who were in CO2-protected spaces when the odorless CO2 gas was discharged accidentally, or without adequate warning to evacuate. This final rule addresses that risk by requiring lockout valves (“lockouts”) and odorizing units (“odorizers”) for most new CO2 systems, specifically those installed or altered after July 9, 2013. (“Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.)

    New CO2 systems protecting spaces containing more than 6,000 cubic feet will need lockout valves. The lockout must be locked in the “off” position during maintenance or testing of a CO2 system, to prevent its accidental discharge during those times of heightened risk to personnel.

    All new CO2 systems will need odorizers. In the event of a discharge, the odorizer will inject a wintergreen scent that will linger as long as harmful amounts of the discharged gas are present, to alert personnel to that presence.Start Printed Page 33861

    Existing Coast Guard regulations require CO2 systems in certain 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 allow their use on smaller “Subchapter K” and “Subchapter T” passenger vessels as well. In recent years, fixed extinguishing systems using “clean agents” have been developed that are comparable to CO2 systems in their ability to suppress fires, but that do not pose the same risks to persons onboard. We would like to spread public awareness that these alternatives exist. We have approved many alternative systems as “regulatory equivalents” to CO2 systems, but the process for requesting and granting an equivalency determination can be burdensome and time-consuming both for regulated entities and for the Coast Guard. We want to update our regulations so that the clean agent systems we have routinely been approving can be used by regulated entities to comply with Coast Guard fire suppression requirements, without the need for obtaining individual equivalency determinations. This should reduce regulatory burden and potentially increase the use of these alternative systems.

    The following table lists the parts within 46 CFR that are affected by the final rule and the specific sections we are amending. The foregoing discussion provides a general summary of the changes. When additional information is required, it appears in the table in parentheses. The table omits any discussion of numerous minor and non-substantive style, format, or wording changes that we are proposing solely to improve the clarity of our regulations.

    V. Discussion of Comments and Changes

    We received 18 written comments from 17 sources (one commenter provided duplicate comments). Of the 17 commenters, seven were individuals or firms that operate vessels, four were trade groups associated with vessel operators, two represented other businesses, one was a fire protection association, one was from an individual employed by a Federal agency, and two did not indicate any particular affiliation. One of the commenters requested a public meeting to discuss the NPRM; we did not grant that request because it was unsupported by any discussion of how a meeting might be beneficial.

    We also received one comment almost a year after the close of the comment Start Printed Page 33862period. The commenter, a manufacturer, said our regulations should allow electric release clean agent fire suppression systems in addition to manual and pneumatic release systems. Although we are not required to respond to late comments, in this case we acknowledge the merit of the suggestion and will consider it either in a future rulemaking or as a type of system we could approve as providing safety equivalent to systems meeting regulatory requirements.

    Scope of the rule. Three commenters asked questions about or commented on the scope of this rulemaking. One expressed the hope that it is not intended to force companies to remove existing fixed carbon dioxide systems and install inferior semi-portable fire extinguishers, which the commenter regarded as less safe than fixed systems. We are not requiring the removal of any existing system. We are providing a regulatory structure for CO2 alternative (clean agent) systems, and requiring some minimal protective measures for new CO2 systems.

    A second commenter inferred that a carbon dioxide lockout would need to be activated even at times when the CO2 system is not undergoing maintenance. Our intention is for the lockout only to be activated when the CO2 system is being tested or maintained, and we have modified the regulatory text to make this clearer.

    The second commenter also asked questions about our proposed lockout exception for spaces smaller than 6,000 cubic feet. In the NPRM, we proposed limiting that exception to those small spaces that provide a means of horizontal escape, like spaces with walk-in/walk-out access. We have decided, for the final rule, to extend the exception to all spaces smaller than 6,000 cubic feet, whether or not they provide horizontal escape routes. Not all small spaces provide walk-in/walk-out access, but in most cases the small space is protected by a CO2 system that protects that space alone. The arrangements for these systems are generally less complex as they serve only one space, and are thus, less likely to discharge inadvertently during system maintenance and testing.

    The third commenter asked if we intend for the rule to apply to foreign-flagged mobile offshore drilling units (MODUs) operating on the U.S. Outer Continental Shelf under a U.S. Certificate of Compliance. This commenter said it would be problematic to apply U.S. type approvals to non-U.S. manufactured carbon dioxide systems on foreign-flagged MODUs. Under 33 CFR 143.207, a MODU documented under the laws of a foreign nation has a choice of design and equipment standards with which it must comply when operating on the U.S. Outer Continental Shelf. It may comply with Coast Guard regulations in 46 CFR part 108, which, as amended by this final rule, include the lockout and odorizer requirements for CO2 systems. It may comply with the documenting nation's standards, if it applies for and receives a Coast Guard determination that those standards provide an equivalent or greater level of safety. In the case of CO2 system lockout and odorizer requirements, an equivalency determination may be given after an applicant demonstrates that the foreign nation's standards require some type of lockout and odorizer or alternative means of providing an equivalent level of safety, though they need not be Coast Guard-approved equipment. Finally, the foreign MODU may comply with the International Maritime Organization's Code for Construction and Equipment of Mobile Offshore Drilling Units, which does not require lockouts or odorizers for CO2 systems.

    Need for the rule. Ten commenters questioned the need for various aspects of this rule. Four commenters questioned the overall need, focusing primarily on the lockout and odorizer requirements. Typical of these four commenters was the remark: “retrofitting the numerous and extremely diverse vessel population this rule would impact would be much more costly than [the Coast Guard's] analysis indicates and would provide a marginal safety advantage, if any.” In the NPRM, we proposed applying those requirements to all vessels, which would have required retrofitting for existing vessels. In the final rule, we have eliminated the provisions that would have required retrofitting, thereby significantly reducing costs and eliminating the disagreement raised by this commenter. Seven commenters said we had failed to demonstrate a need for lockouts, and five said we failed to show the need for odorizers. Many pointed out that lockouts would not have prevented many of the reported carbon dioxide-related casualties in recent years, and that we cited no studies to show that odorizers would provide better protection than the audible and visual alarms that already protect most vessels.

    In response to these comments, we will not require the retrofitting of existing CO2 systems, but we will apply the lockout and odorizer requirements only to new CO2 systems regardless of vessel class. Although we have only limited casualty data for some vessel classes, we think the risk of inadvertent CO2 system discharge is common to all classes and requires a uniform regulatory approach. Furthermore, while alarms provide advance warning of an imminent discharge, they do not provide similar protection after a discharge when pockets of CO2 can pose a serious risk of fatality. Similarly, lockouts provide better protection than alarms in scenarios where evacuation is not feasible despite the advance warning provided by alarms.

    We acknowledge that our lockout and odorizer requirements may not eliminate the risk of casualties related to CO2 exposure, but we believe they will reduce that risk. CO2 exposure is a potential health hazard recognized by government agencies like the National Institute of Occupational Safety and Health (see their publication NIOSH 76-194, “Criteria for a Recommended Standard—Occupational Exposure to Carbon Dioxide,” available at http://www.cdc.gov/​niosh/​76-194.html) and the Environmental Protection Agency (EPA), and by industry groups like the National Fire Prevention Association (NFPA). Internationally, 19 incidents since 1980, involving 55 deaths and at least 29 injuries, indicate the reality and extent of the risk with respect to marine CO2 fire suppression systems. To the extent U.S. vessels are equipped with those systems, we think they share in that risk.

    Two commenters questioned the need for lockout or odorizer requirements on passenger or towing vessels, which are already required by Coast Guard regulations to have central alarms that sound in advance of a carbon dioxide discharge. Lockouts and odorizers provide protection that alarms and discharge delays cannot. The lockout is a positive control to prevent discharge into protected spaces during maintenance and testing, when any other safety control or method may be turned off or potentially misaligned. Unlike alarms, odorizers are not primarily intended to notify persons who are in a protected space when CO2 is inadvertently discharged. The odor allows crewmembers to positively identify where the gas has lingered in protected spaces or migrated to other spaces after an intentional or inadvertent release. This is important, as CO2 gas is heavier than air and can easily migrate or collect in unanticipated areas even after the spaces have been ventilated naturally or mechanically.

    Alternative systems. Five commenters addressed our proposals for CO2 alternative fire protection systems. One of the five said that if there are safer Start Printed Page 33863alternatives that work as well as carbon dioxide, “those systems ought to be considered and offered as options.” The other four generally agreed with the comment that recognition of “other clean agent systems appears to be overdue and should go forward.” We agree with these comments.

    One commenter, an EPA employee, recommended limiting the use of carbon dioxide systems in new installations. Another commenter recommended incorporating the 2010 version of NFPA 13, a standard for sprinkler systems, in 46 CFR part 34, instead of the 1996 edition that we currently incorporate by reference, and also recommended incorporating NFPA standards for water mist, spray, and foam fire suppression systems. These recommendations are beyond the scope of this rulemaking, and not necessary to reach our regulatory goals of providing protective measures where CO2 systems are used and a regulatory structure for CO2 alternative (clean agent) fire suppression systems.

    Lockouts. Twelve commenters addressed the NPRM's proposed requirement for lockouts on carbon dioxide systems. One of these acknowledged that lockouts could be useful when persons unfamiliar with a vessel perform maintenance on the CO2 system. Two commenters agreed with our proposal, one of them pointing out that lockouts “are widely used low-cost methods for reducing the risk to personnel in spaces protected with carbon dioxide.”

    Four commenters questioned the need for, or effectiveness of, lockouts. Three of the four said vessel operators already use rigorous procedures, sirens, and strobe lights to warn personnel in the event of a carbon dioxide discharge. The fourth pointed out that, during CO2 system maintenance, a trained and certified manufacturer's representative should always be present to ensure that written safety protocols are observed, and that the crew should verify compliance with those protocols. In his view, therefore, lockouts are not needed. Our position is that lockouts provide protection that the measures cited by these commenters cannot. The lockout valves are intended to provide protection during repair and maintenance procedures to the system, preventing an accidental discharge with a positively closed valve, whereas existing measures simply warn of an impending accidental (or intentional) discharge. There are many ways in which a CO2 system can discharge inadvertently during maintenance and testing. Because each system is uniquely engineered and arranged to suit the space it protects, even experienced technicians may be unfamiliar with a system designed to protect multiple spaces with multiple actuation methods and locations. The lockout gives the master or person-in-charge an ultimate, positive control to prevent discharge into protected spaces at a time when any other safety controls may be turned off or potentially misaligned.

    Five commenters said the lockout requirement might have unintended adverse consequences. A typical comment from these five said that personnel might fail to reopen the lockout once the need for closing the CO2 system ends, and that this failure might not be noticed until a fire triggers the need for the CO2 system to discharge. The commenter contrasted that possibility with electrical systems, where inadvertent failure to reopen a lockout would result in continued disruption of electrical service and would be noticed immediately. Turning the valve on and off each time a crewmember enters a protected space is not the intended use of the valve. Our regulatory text now clarifies that the lockout is to close the system only during system maintenance and testing, and that the master or person-in-charge must ensure that the valve is locked open when maintenance or testing is completed. Finally, we will ensure that when we review a manufacturer's maintenance manual, we verify that using and unlocking the lockout valve is discussed in the manual's maintenance procedures. Such procedures have proven to be effective where CO2 lockout valves have been used.

    Another commenter suggested that, instead of requiring the master to ensure that a carbon dioxide system is returned to service after maintenance, we should require “a lockout/tag-out system, which is a more generally accepted method to ensure that each valve * * * is correctly positioned after maintenance.” We support, but do not require, the use of lockout/tag-out systems, and believe we achieve similar protection by requiring the lockout design or locking mechanism to make it obvious whether the valve is open or closed.

    Four commenters suggested alternatives or modifications to our proposal. One commenter cited the International Maritime Organization's International Code for Fire Safety Systems (FSS Code) requirement for the use of two independent valves to control the release of a CO2 system and, noting that the FSS Code also allows for the use of a lock box and key to prevent activation of the flooding system, said that “[a]s the lock box is designed to work with an existing system controls it will be easier to install and maintain” than a lockout valve. We also require a dual-action release arrangement on most spaces larger than 6,000 cubic feet, and passenger vessels are required to have a locked box to protect the release handles against inadvertent discharge. The locked boxes and dual action releases help to ensure that the system is only activated when intended, and that the agent is released to the desired space during an emergency. The use of a locked box reduces the probability of tampering or inadvertent release by inquisitive or malicious passengers. Lockout valves, on the other hand, serve to protect personnel during system maintenance and testing, when accidental discharges have been known to occur.

    A second commenter suggested that, as an alternative to requiring lockouts, a “better approach for life safety would be to prohibit new installations of carbon dioxide systems.” This suggestion is beyond the scope of this rulemaking, which seeks only to provide protective measures where CO2 fire suppression systems are used, and to provide a regulatory structure for CO2 alternative (clean agent) systems.

    Finally, a third commenter said we should substitute “master or person-in-charge” for “master” as the person responsible for ensuring the reopening of carbon dioxide system valves after maintenance, because not all vessels use masters, or use masters only when the vessel is underway. We have made the suggested change.

    Odorizers. Eleven commenters addressed our odorizer proposal. Two supported our proposal, and one of these two said odorizers “are widely used low-cost methods for reducing the risk to personnel in spaces protected with carbon dioxide.”

    One commenter asked if we intended to require adding wintergreen scent directly to the carbon dioxide gas stored in system cylinders, or if we intended to require even hand-held pressurized CO2 cylinders to be odorized. Neither is our intent. However, if it ever becomes feasible to odorize CO2 directly in the cylinder, this could be considered for approval as a regulatory equivalent to our requirement for the CO2 system to have an approved odorizing unit.

    Seven commenters questioned the effectiveness of an odorizer requirement. Most asked why we think odorizers are superior to the sirens, strobe lights, or other alarms they already use to warn personnel in the event of a carbon dioxide discharge. In our view odorizers are not necessarily superior to those other alarms, but a Start Printed Page 33864natural complement to existing protective measures. Alarms are intended to alert personnel in the protected space when a CO2 system discharges. The alarm is short and stops once the gas has stopped flowing from the storage bottles. Because the gas is naturally odorless and colorless, the addition of an odorizer will signal to personnel where the CO2 gas is and will provide notice as long as it remains, and will continue to provide an alert to danger after discharge. Further, the odor provides easy indication if it remains in the protected space or if the gas has migrated, perhaps unexpectedly, to other compartments. Being alerted to where the CO2 gas is and how long it remains should enhance the safety of personnel. The longstanding use of mercaptan to signify the presence of natural gas and the successful use of wintergreen odorizers for shore-based CO2 systems show the validity of such requirements. For example, the Nuclear Regulatory Commission's NRC Information Notice 99-05 describes an incident in which a security guard was alerted to the dangerously concentrated presence of migrated CO2 in an area outside of a protected space by its wintergreen scent. With crew familiarization, and the explanatory signage we require, personnel will become accustomed to wintergreen being associated with CO2 discharges, just as they learn to differentiate other alerts such as bells and sirens in their workplace.

    One commenter pointed out that carbon dioxide casualties in recent years have resulted from persons being trapped in spaces during carbon dioxide discharges, and not from a lack of warning. We acknowledge that odorizers, by themselves, will not prevent a trapping incident. However, the odorizer will at least give a person additional warning that he or she should exit the space if possible and it may also alert others nearby who can help extricate any trapped person, and will alert individuals to potentially dangerous concentrations post-discharge.

    Another commenter asked whether an offensive odor might work better than wintergreen, and raised practical concerns about how the crew would recognize the scent if it was masked by other environmental conditions, such as the presence of perfume or cleaning agent odors. We chose wintergreen because it is required, except when it is already in common use for non-emergency purposes in the system location, by the National Fire Protection Association's commonly-used NFPA 12 Standard on Carbon Dioxide Extinguishing Systems, and therefore is widely and inexpensively available. Personnel are likely to respond to an unusual scent without regard to how pleasant it smells, especially if they are trained to do so. If other environmental odors are strong enough to cause notice, they will prompt a simple investigation that presumably will quickly allay concerns of a CO2 leak. Wintergreen is used on shore-based systems in part to avoid confusing a CO2 presence with the presence of mercaptan-laced natural gas.

    Three commenters suggested alternatives to our proposal. As other commenters also observed, one commenter said wintergreen may be confused with other scents in use on the vessel. Therefore this commenter suggested using an odor other than wintergreen, or adding color to the carbon dioxide gas. Our existing regulations allow for the approval of regulatory equivalents when strict compliance with regulatory requirements is impractical, and when there are alternatives that can be shown to achieve the same level of safety that the regulations provide. Owners and operators who find it impractical to use the wintergreen odor may have another odor approved under these equivalency provisions. However, we expect most systems to use wintergreen, given its acceptance for shore-based systems under NFPA 12 and its wide and inexpensive availability. The success and availability of wintergreen additives in the shore-based systems provide the basis for choosing this as the standard. We will continue to monitor industry standards for the success of alternative scents or adding color to carbon dioxide gas.

    A second proponent of alternatives suggested prohibiting the installation of new carbon dioxide systems instead of requiring systems to be odorized. This comment is beyond the scope of this rulemaking, which seeks only to provide protective measures where such systems are used, and to provide a regulatory structure for CO2 alternative (clean agent) fire suppression systems.

    The third proponent of alternatives suggested using plastic wrap to detect leaks rather than requiring odorizers. This suggestion is also beyond the scope of this rulemaking. Further, it would only help those looking for a leak to detect it, assuming the wrap happened to be in place at the location of the leak, but it would not alert persons who are engaged in other activities at the time of an indavertant discharge as the odorizers are designed to do. Existing requirements for annually validating the weight of fire suppression agents provide routine protection against the small leaks that the commenter's suggestion would target, but they do not focus on the full discharge that is the focus of this rulemaking.

    Cost information. Eight commenters provided information about the cost of our proposals. One commenter provided a combined estimate of $3,472 to meet both the lockout valve and odorizer proposals.

    Four commenters provided cost estimates for lockout valves. Two of these supplied estimates ranging between $800 and $1,800 per lockout valve. A third estimated that a lockout valve for a less-than-2-inch pipe would cost $2,895. The fourth estimated that the total cost of lockouts for the commenter's 30 vessels would be $175,000, but did not estimate the total number of lockouts that would be required.

    Three commenters provided cost estimates for odorizers. One said the cost of odorizing a system would be $400. Another estimated the cost at $3,225, and had received a discounted estimate of $25,329 for eight tanks. The third estimated the cost, for 30 vessels, as $75,000, but did not indicate how many tanks would require treatment.

    We have incorporated the additional specific cost information provided by these commenters as appropriate based on the completeness of data and sources provided. This final rule reflects new national average costs accordingly. In the NPRM, we gave the national average cost for lockout valves under two inches as $1,258, and $3,188 for lockout valves two inches or more in length. The new figures are $2,076 and $4,925 respectively.

    Four commenters, some of whom acknowledged that the costs of our specific proposals might be reasonable, stated that our proposals were unreasonable when considered cumulatively with the cost of other recent Federal regulations, including Coast Guard regulations, affecting vessel owners and operators. Two of these commenters operate dinner cruise vessels, and cited their inability to pass these cumulative costs to their customers without harming their ability to compete with land-based recreational attractions not subjected to marine safety regulations. We reviewed our proposed regulation in light of the cost concerns cited by commenters, and we have modified the regulatory text for the final rule to minimize costs. Existing vessels will not be affected by our lockout and odorizer requirements unless they install or alter a CO2 system. We encourage vessel owners and operators to voluntarily modify existing CO2 systems to include lockouts and Start Printed Page 33865odorizers, but we will not require them to do so. We acknowledge the new Executive Order 13563 of January 2011 (“Improving Regulation and Regulatory Review”) that asks Federal regulatory agencies to “tailor regulations to impose the least burden on society, consistent with obtaining regulatory objectives, taking into account, among other things, and to the extent practicable, the costs of cumulative regulations.” In this rule, we have sought to minimize the cumulative impacts on industry by removing the NPRM requirements for existing vessels unless the CO2 system is altered. Consequently, in this final rule we reduced the incremental cumulative cost to industry from the NPRM's figure of $9.8 million to $2.3 million, a reduction of $7.5 million or 77 percent over 10 years (using a 7-percent discount rate).

    Regulatory analysis. One commenter, an industry association, stated the breakeven analysis is contradicted by actual experience since the Coast Guard found no CO2-related fatalities in the U.S. commercial fleet in 13 years. The commenter also said we did not account for other factors that might have been involved in the casualties linked to carbon dioxide discharges, pointing out that many casualties occurred on foreign-flagged or naval vessels that would not be subject to our rule, and said we should have included in the rulemaking docket those NFPA and EPA studies that we discuss in the analysis. We acknowledge that most of the CO2 casualties occurred on foreign vessels or naval vessels. However, the hazard and vessel similarities suggest a risk remains on U.S. flag commercial vessels. The primary hazard in the incidents mentioned above was an unintended or accidental CO2 release. The breakeven and uncertainty analysis in the preliminary regulatory analysis for the NPRM acknowledged many of these concerns. The breakeven analysis of the NPRM (which included all new and existing fire suppression systems on certain classes of commercial vessels) found that the rule would need to prevent 0.22 fatalities per year to break even, or about one fatality every 4-5 years. By extension, breakeven could be achieved by preventing multiple fatalities over longer periods. This analysis did not include the value of potential non-fatal injuries and secondary impacts. As this rulemaking seeks to reduce risk to the crew on vessels with CO2 fire suppression systems, the potential value of the avoided damages at risk is quite large in comparison to the relatively minor costs of the proposed safety measures in the NPRM. In addition, we further minimized costs in this final rule by removing the NPRM requirements for all existing vessels unless the CO2 system is altered (in which case, that smaller subset of vessels would be going through a refurbishment). We believe this balance of both reduced costs and reduced risks makes this final rule the most effective alternative. We do not believe “no action” is an alternative given the inherent risks with CO2 fire suppression systems. Coast Guard accident data reveal two more recent casualties, from a single incident, that were not reflected in our original analysis for the NPRM. Those casualties (crewmembers) recovered, but their exposure to an accidental release of carbon dioxide demonstrates that a risk remains with CO2 fire suppression systems. We have modified the breakeven analysis for the final rule to reflect the revised applicability and reduced cost. The final rule would need to prevent one fatality every 27 years for the benefits of the rule to equal or exceed the costs. Regarding the EPA and NFPA reports, we did not place them on the docket because the EPA report is accessible online at http://www.epa.gov/​ozone/​snap/​fire/​co2/​co2report.pdf and the NPFA reports are available free online as read-only documents at http://www.nfpa.org/​aboutthecodes/​AboutTheCodes.asp?​DocNum=​12.

    Timing of implementation. One commenter criticized as “inadequate,” without further explanation, the NPRM's proposal for a 5-year phase-in of lockouts and odorizers for existing carbon dioxide systems. We have modified these requirements in the final rule so that they will not affect existing systems, only new CO2 systems.

    Small business impacts. One commenter stated that most domestic passenger vessels are operated by small businesses or small entities. Given absence of documented need for application of the proposed rule to this sector of the maritime industry, the Coast Guard has a statutory duty to more rigorously examine the proposal's consequences for small businesses and entities. In the NPRM and its supporting regulatory analysis on the docket, we summarized and prepared an initial regulatory flexibility analysis discussing the impacts of this proposed rule on small entities. We performed this analysis as required by the Regulatory Flexibility Act (5 U.S.C. 601-612). As required by section 603(b) of the Act, we provided detailed discussion in response to the following: (1) A description of the reasons why action by the agency is being considered; (2) a succinct statement of the objectives of, and legal basis for, the proposed rule; (3) a description of and, where feasible, an estimate of the number of small entities to which the proposed rule will apply; (4) a description of the projected reporting, recordkeeping and other compliance requirements of the proposed rule, including an estimate of the classes of small entities which will be subject to the requirement, and the type of professional skills necessary for preparation of the report or record; (5) an identification, to the extent practicable, of all relevant Federal rules which may duplicate, overlap or conflict with the proposed rule; and, under section 603(c) of the Act, a description of any significant alternatives to the proposed rule which accomplish the stated objectives of applicable statutes and which minimize any significant economic impact of the proposed rule on small entities. After performing and documenting this analysis, we found that we could certify 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 solicited public comments on this finding. We reviewed our proposed regulation in light of the cost concerns cited by commenters, and we have modified the regulatory text for the final rule to minimize costs to small entities, eliminating the need for existing vessels to meet our lockout and odorizer requirements unless they install or alter a CO2 system.

    Preemption. Throughout this final rule, we have added new text explaining the preemptive effect of our regulations. See the “Federalism” discussion in part VII.E of this preamble for a full discussion.

    Beyond scope of rulemaking. One commenter said carbon dioxide systems should be banned for new and retrofit installations because of the availability of better alternatives, and that we should ban gas-driven alarms and shutdowns in favor of alarms and shutdowns that are not gas-driven. A second commenter said the Coast Guard should routinely hold at least one public meeting in connection with any rulemaking. These suggestions are all beyond the scope of this rulemaking, which seeks only to provide protective measures where carbon dioxide systems are used, and to provide a regulatory structure for CO2 alternative (clean agent) fire suppression systems.

    VI. Incorporation by Reference

    The Director of the Office of the Federal Register has approved the material in 46 CFR 34.01-15, 147.7, and Start Printed Page 33866162.161-2 for incorporation by reference under 5 U.S.C. 552 and 1 CFR part 51. Copies of the material are available from the sources listed in those sections.

    VII. Regulatory Analyses

    We developed this rule after considering numerous statutes and executive orders related to rulemaking. Our analyses based on 14 of these statutes or executive orders are presented below.

    A. Regulatory Planning and Review

    Executive Orders 12866 (“Regulatory Planning and Review”) and 13563 (“Improving Regulation and Regulatory Review”) direct agencies to assess the costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). Executive Order 13563 emphasizes the importance of quantifying both costs and benefits, of reducing costs, of harmonizing rules, and of promoting flexibility. This final rule is not a significant regulatory action under section 3(f) of Executive Order 12866. The final rule has not been reviewed by the Office of Management and Budget. A Final Regulatory Analysis is available in the docket as indicated under ADDRESSES. A summary of the Final Regulatory Analysis follows:

    Table 2 summarizes a comparison of the costs and benefits of the NPRM and the final rule:

    Table 2—Comparison of Impacts Between NPRM and Final Rule

    CategoryNPRMFinal ruleChange/reason
    Affected population• Retrofit systems on existing vessels: 3,204 existing CO2 systems would require lockout valves • New systems on new vessels: 34 new CO2 systems would require lockout valves per year. • All existing vessels require odorizers for 7,815 CO2 systems. New vessels require odorizers for 46 CO2 systems per year.• No retrofits • Lockout valves required for about 2 altered CO2 systems per year for existing vessels • New systems on new vessels: 53 CO2 systems required lockout valves per year • Odorizers required for about 5 modified or replaced systems per year for existing vessels. New vessels require odorizers for 128 CO2 systems per year• Final rule does not include requirements for existing vessels to retrofit and install lockout values and odorizers unless the CO2 system is altered. • Data refreshed for new construction totals.
    Unit costs that have changed: Lockout valves *• Under 2 inches: $1,258 • Over 2 inches: $3,188.• Under 2 inches: $2,076 • Over 2 inches: $4,925.• Unit costs increased for lockout valves based on data and information provided in public comments.
    Costs (based on 7% discount rate and 10 year period of analysis)• 10-year costs: $9.8 million • Annualized costs: $1.4 million.• 10-year costs: $2.3 million • Annualized costs: $233,000 (rounded)• Cost reduced since final rule does not include requirements for existing vessels to retrofit and install lockout values and odorizers unless the CO2 system is replaced, altered, or added. • Unit costs increased for lockout valves based on data and information provided in public comments. However, the increased cost estimate for lockout valves is greatly offset by the removal of requirements for existing vessels as previously discussed.
    BenefitsThe primary benefit is the reduction in risk of crew injuries and fatalities related to CO2 exposure from fire suppression system discharges in existing vessels and new constructionThe primary benefit of this final rule is the reduction in risk of crew injuries and fatalities related to CO2 exposure from fire suppression system discharges in refurbished existing vessels and new constructionFinal rule scope of benefits is for systems on new vessels and existing vessels as systems are altered, resulting in lowering risk reduction. While not quantified, the benefits of this final rule are reduced compared to the proposed rule since these systems are being phased in more slowly.

    Breakeven analysis **The NPRM (which included all existing vessels) would need to prevent about 0.22 fatalities per year or about 1 fatality every 4-5 years for the benefits of the NPRM to equal or begin to exceed the costs. This analysis did not include the value of potential non-fatal injuries and secondary impactsThe final rule would need to prevent about .037 fatalities per year or about one fatality every 27 years for the benefits of the final rule to equal or begin to exceed the costs. This analysis does not include the value of potential non-fatal injuries and secondary impactsAs a result of reduced costs, the breakeven analysis suggests that it would take very little monetized benefits for the final rule to equal or begin to exceed costs. Consequently, there is a 5-7 fold decrease in mishap frequency needed for the benefits of this rule to equal or exceed the costs.
    * These are average unit costs for lockout valves. Final rule unit cost estimates for odorizers did not change since the NPRM.Start Printed Page 33867
    ** Breakeven analysis answers the question, “How small could the value of the non-quantified benefits be before the rule would yield zero net benefits?” OMB guidance also acknowledges that it will not always be possible to express in monetary units all of the important benefits of a rule. See OMB Circular A-4 “Regulatory Analysis” (2003), page 2.

    The purpose of this final rule is to advance the Coast Guard's strategic goals of marine safety and maritime mobility by clarifying and codifying the requirements for fire suppression systems that use carbon dioxide alternatives, and by requiring lockout valves and odorizers to provide safety on certain vessels that use carbon dioxide fire suppression systems. This final rule applies two new requirements that have additional costs to industry, lockout valves and odorizers, to all CO2 suppression systems installed or altered after July 9, 2013. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual. Lockout valves must be installed in systems protecting any space with a gross volume greater than 6,000 cubic feet. According to Coast Guard Marine Investigation Security and Law Enforcement (MISLE) data, this requirement will affect an average of 53 systems on new vessels and about two systems on existing vessels each year. Odorizers must be installed in CO2 systems for new vessels and existing vessels with altered systems. According to MISLE data, this requirement will affect an average of 128 CO2 systems of all sizes on newly constructed vessels and about five systems of all sizes on refurbished vessels each year.

    Under the NPRM, all affected commercial vessels would have been required to install lockout valves and odorizers. This would have required existing commercial vessels to retrofit these devices. A major change from the NPRM is that the final rule will only affect newly constructed commercial vessels and those commercial vessels that may have alterations of existing systems. Furthermore, NPRM commenters provided additional data on the costs of lockout valves, which has been incorporated into our estimates and results in a higher unit cost for lockout valves. As a result of the adjustments to the proposed regulation, total costs for the final rule decrease in comparison to the NPRM despite an increase in unit cost for lockout valves.

    Based on industry data and public comments, we estimate the average industry prices for installing retrofit large and small lockout valves on new vessels to be $4,925 and $2,077, respectively. Systems that handle more than 2,450 pounds of CO2 require a valve larger than 2 inches. Of the two systems for refurbished vessels affected annually by this proposed rule, .7, on average, would require the larger, more expensive lockout valves, while 1.4, on average, systems require the smaller valves for a total undiscounted cost of about $6,184. Of the 52.5 systems for newly constructed vessels affected annually by this rule, 17.3 would require the larger, more expensive lockout valves, while 35.2 systems require the smaller valves for a total undiscounted cost of about $158,368. The annual undiscounted cost for owners of newly constructed and refurbished vessels with systems to meet the lockout valve requirement of this rule would be approximately $164,552 for each year. Industry would incur this cost for each year over the ten-year period of analysis.

    As for odorizers, we estimate that the installed costs, including three warning signs, are $516/unit based on industry information. We estimate the total annual undiscounted cost of the refurbished vessels to be $2,582. For systems on newly constructed vessels, the total undiscounted annual cost is $66,105. We estimate the total annual undiscounted cost to be about $68,687 for all 133 CO2 protected areas on these vessels. The total cost per vessel would be dependent on the number of areas protected by CO2.

    The total annual undiscounted cost for both lockout valves and odorizers for new or refurbished vessels is about $233,000 (rounded). We estimate the total present value 10-year cost of the final rule to be $1.638 million at a seven percent discount rate. This represents about an 83-percent cost reduction from the NPRM total present value 10-year cost estimate of $9.8 million. We estimate the annualized cost of the final rule to be $233,000 compared to $1.4 million for the NPRM (estimates using a seven percent discount rate).

    This final rule also issues new regulations for installing, maintaining, and using approved CO2 alternative (clean agent) fire suppression systems. We believe this promotes safety and is advantageous to industry since these alternative systems provide additional flexibility to industry and formalizes the Coast Guard's policy of approving these alternative systems. Commenters supported the NPRM provisions for alternative systems (see “Discussion of Comments and Changes”).

    As discussed in the NPRM, this rule clarifies Coast Guard approval of alternatives to using CO2 systems. We estimate that these provisions will not have an additional cost impact because the Coast Guard has been approving alternative systems on an ad hoc basis. We expect these approved installed alternative systems will be compliant with the requirements for alternative systems proposed in this rule. We did not receive comments to the NPRM on additional costs for these regulations for alternative systems. In addition, the use of halocarbon (one of a number of alternatives) fire suppression systems has been making steady inroads in recent years (2006-2010). As discussed in the NPRM, our updated records indicate that industry installed an average of 32 halocarbon fire suppression systems compared to an average of 65 CO2 fire suppression systems with capacity over 6,000 cubic feet annually.

    Benefits

    The primary benefit associated with this 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, in its publication NIOSH 76-194, “Criteria for a Recommended 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 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.

    We searched the MISLE database for casualty reports between 1996 and 2010 to find personnel casualties related to CO2 fire suppression systems discharged in areas with personnel. We found one non-fatal incident in the U.S. commercial fleet during the 15-year period analyzed for this rulemaking. As previously stated, CO2 flooding can Start Printed Page 33868cause fatalities to people who are in CO2-protected spaces when the odorless CO2 gas is discharged accidentally, or without adequate warning to evacuate. Exposure to an accidental release of carbon dioxide demonstrates that a risk remains in the regulated fleet covered by this rule. The danger of CO2 flooding can be reduced by the use of lockout valves that are locked “off” when someone is conducting maintenance in the CO2 system as well as the use of odorizers to help the person at risk detect CO2 discharges.

    In addition, there have been incidents in military and foreign fleets. Due to these aggregate incidents, we conclude that some (unquantifiable) risk remains present. Given this situation, wherein we are not able to quantify the remaining risk and risk reduction for the purposes of this rulemaking, we used a “breakeven analysis” to understand the benefits of this rule.

    In breakeven analysis, we compare the known costs to an estimate of a loss to determine a threshold. In safety regulations, it is common to use the “value of a statistical life” (VSL) concept to measure a loss. The VSL is not meant to be an estimate of the actual value of a life, but a measure of society's willingness to pay to reduce small risks of fatalities. Using the annualized costs at a seven percent discount rate over a ten-year period, or $233,320 for the final rule, we can compare it to the VSL's $6.3 million.[1] The final rule would need to prevent 1 fatality in 27 years, or 0.037 fatalities per year to break even. The NPRM (which included all new and existing fire suppression systems on certain classes of commercial vessels) would have needed to prevent about 0.22 fatalities per year or about 1 fatality every 4-5 years for the benefits of the NPRM to equal or begin to exceed the costs. The breakeven analysis of the NPRM and final rule did not include the value of potential non-fatal injuries and secondary impacts.

    Finally, a secondary benefit of this rule is the expediting of applications for approval of alternative systems. These systems, using non-CO2 agents, have been approved on a case-by-case basis for years. The final rule will make these requirements clearer. These qualitative changes of reducing transaction costs are not easily translated into quantitative cost impacts, so none were estimated. In addition, the increased clarity with regards to the requirements for alternative systems may foster the increased development and use of these potentially safer systems.

    Regulatory Alternatives

    We considered three alternatives for this rulemaking:

    Alternative One—No action. We rejected this alternative as unacceptable since risk would remain under the existing regulations. Also, because the current regulations do not specifically address the use of alternative “clean agent” fire suppression systems, there would be continued uncertainty in selecting and using these systems as well as obtaining Coast Guard approval for them. This alternative was rejected for both the NPRM and the final rule.

    Alternative Two—Ban the use of CO2 fire suppression systems. While a risk exists, a complete prohibition of CO2 systems could require a complete retrofit of existing commercial vessels affected and be prohibitively expensive. This alternative was rejected for both the NPRM and the final rule.

    Alternative Three—Amend Coast Guard regulations to clarify that approved alternatives to CO2 systems are permissible, to set general parameters for those alternative systems and for getting them approved, and to require the use of lockout valves and odorizers in all spaces protected by CO2 systems on new and refurbished vessels. In our view, this alternative is the best approach to reducing risk and minimizing cost to the marine industry as we are aware that CO2 generally remains the least expensive agent available for these systems. Consequently, this alternative was used as the basis for the NPRM for new construction and all existing fire suppression systems on certain classes of commercial vessels in a retrofit mode. After reviewing public comment and considering the amended cost basis, we have amended the rules proposed in our NPRM and will apply this regulation only to new or refurbished vessels. This final rule Alternative Three is a modification of the NPRM Alternative Three.

    B. Small Entities

    Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have considered whether this rule would have a significant economic impact on a substantial number of small entities. A final regulatory flexibility analysis discussing the impact of this final rule on small entities is available in the docket and contained in the final regulatory analysis where indicated under ADDRESSES.

    The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000.

    The entities affected by this proposed rule are generally found under the North American Industry Classification System (NAICS) codes for water transportation. The most common NAICS codes include the following 6-digit NAICS codes for marine transportation: 483212-Coastal and Great Lakes Freight Transportation, 487210-Scenic and Sightseeing Water Transportation, and 532411-Commercial Air, Rail, and Water Transportation Equipment Leasing. A complete listing of the relevant NAICS codes may be found in the NPRM's regulatory analysis. We examined employment levels and revenue of the entities that will be affected by this final rule and based on the available data; we estimate that about 56 percent of entities affected by the final rule requirements are small under the Regulatory Flexibility Act and the SBA size standards.

    The final rule's regulatory analysis used a higher unit cost adjusted as a result of comments received on the NPRM. This higher unit cost increased the cost impacts on revenue for affected entities. This did not change our overall finding from the NPRM that this rule did not have a significant economic impact on a substantial number of small entities. As previously explained, we have significantly reduced the scope of this regulation compared to the proposed rule. We estimated the proposed rule would have directly regulated approximately 400 small entities, while we estimate this final rule will directly regulate only 31 small entities.

    As a result of our analysis of 2010 MISLE data on new construction vessels and refurbishment vessels, we concluded that small entities likely comprise 56 percent (or approximately 31 unique businesses) of the total population evaluated. Of these 31 businesses, we found revenue data on 15 entities. The balance of 16 unknown size entities was assumed to be small by SBA standards. Under our methodology, we assume an entity is small unless we can find evidence that indicates it is not. We determined that 80 percent of Start Printed Page 33869small entities would have an annual revenue impact of less than 1 percent. Further, we estimated that the impact on 93 percent of these small entities would be less than 3 percent of annual revenue. Table 3 provides details of these conclusions.

    Table 3—Comparison of NPRM and Final Rule Revenue Impacts

    CategoryNPRM resultFR resultChange

    1% < Impact ≤ 3%16%13%
    3% > Impact ≤ 5%7%
    Total100%100%
    Source: USCG Calculations.

    The final rule reduced the impact on the number of small entities affected since the vessels affected are a much smaller group of new construction and refurbished vessels and excludes the retrofit vessels originally included in the NPRM. By reducing the scope of this final rule in response to public comment, we have reduced the revenue impact not only on the whole industry, but on the small entities as well.

    Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this final rule will not have a significant economic impact on a substantial number of small entities.

    C. Assistance for Small Entities

    Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we offered to assist small entities in understanding the rule so that they could better evaluate its effects on them and participate in the rulemaking. 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 final rule would not require a new collection of information or a revision to an existing collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The Coast Guard did not receive any COI-related comments to the NPRM.

    The Coast Guard has been approving alternatives to CO2 systems under an approved collection, OMB Control Number 1625-0035. Satisfactory lockout valve and odorizing unit installation will be confirmed under current 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 evaluated this rule under E.O. 13132 and have determined that they are preemptive of State law or regulation in that Congress intended the Coast Guard to regulate the type and design of fire suppression systems aboard certain vessels. The regulations listed in this rulemaking are promulgated pursuant to 46 U.S.C. 3306, 3703, 4102, 4306, and 4502.

    It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled, now, that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 8101 (design, construction, alteration, repair, maintenance, operation, equipping, personnel qualification, and manning of vessels) are within the fields foreclosed from regulation by the States (See the decision of the Supreme Court in the consolidated cases of United States v. Locke and Intertanko v. Locke, 529 U.S. 89, 120 S.Ct. 1135 (March 6, 2000)). For those regulations promulgated under 46 U.S.C. 3306 and 3703, Congress directed the Secretary to prescribe regulations that would require equipment used in firefighting and fire prevention aboard certain inspected vessels. Here, the Coast Guard is promulgating regulations to require enhanced or alternative safety features on firefighting systems on board inspected vessels defined in 46 U.S.C. Chapters 33 and 37, which will improve safety. Because States may not promulgate rules within this category, preemption is not an issue under Executive Order 13132.

    Under 46 U.S.C. 4102, Congress mandated certain uninspected vessels, defined within 46 U.S.C. Chapter 41, to be equipped with fire extinguishers that meet the requirements prescribed by regulation. The Coast Guard, in considering the safety features necessary to extinguish fires promptly and effectively and, to the extent required in consultation with the Towing Safety Advisory Committee, has promulgated regulations requiring certain equipment features for uninspected vessels. These regulations do not raise any preemption concerns under Executive Order 13132 since States may not promulgate rules within this category of uninspected vessels.

    Congress mandated the Coast Guard to promulgate regulations requiring safety standards for fire extinguishers aboard uninspected commercial fishing vessels defined in 46 U.S.C. Chapter 45. Those regulations promulgated under 46 U.S.C. 4502 require certain features to make fire extinguishers readily identifiable and accessible in accordance with Congress's mandate. Because States may not promulgate rules within this category, preemption is not an issue under Executive Order 13132.

    Regulations issued pursuant to 46 U.S.C. 4302 are preemptive of State law to the extent outlined in 46 U.S.C. 4306. Under 46 U.S.C. 4306, Federal regulations establishing minimum safety standards for recreational vessels and associated equipment and the procedures and tests established to measure conformance with those standards preempt State law, unless the State law is identical to a Federal regulation, or a State is specifically provided an exemption to those regulations, or permitted to regulate marine safety articles carried or used to address a hazardous condition or circumstance unique to that State.Start Printed Page 33870

    Additionally, President Obama's Memorandum of May 20, 2009 titled “Preemption” states that “preemption of State law by executive departments and agencies should be undertaken only with full consideration of the legitimate prerogatives of the States and with a sufficient legal basis for preemption.” To that end, when a department or agency intends to preempt State law, it should do so only if justified under legal principles governing preemption, including those outlined in Executive Order 13132, and it should also include preemption provisions in the codified regulation. In accordance with this memorandum, the Coast Guard has included in the final rule regulatory text the statutory provisions granting it preemption authority as well as language indicating its intent to preempt conflicting state or local regulation, when required.

    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 (adjusted for inflation) or more in any one year. Though this rule will not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble.

    G. Taking of Private Property

    This rule will not cause 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 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 rule under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This rule is not an economically significant rule and does not create an environmental risk to health or risk to safety that may disproportionately affect children.

    J. Indian Tribal Governments

    This rule does not have tribal implications under Executive Order 13175, Consultation and Coordination With Indian Tribal Governments, because it does 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 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 standards bodies.

    This rule uses the following voluntary consensus standards: Underwriters Laboratories (UL) standards UL 2127 “Standard for Inert Gas Clean Agent Extinguishing System Units,” and UL 2166 “Standard for Halocarbon Clean Agent Extinguishing System Units,” and National Fire Protection Association (NFPA) standard 2001 “Standard on Clean Agent Fire Extinguishing Systems.” The sections that reference these standards and the locations where these standards are available are listed in the regulatory text for 46 CFR 34.01-15, 147.7, and 162.161-2.

    This rule also uses technical standards other than voluntary consensus standards. The test described in the regulatory text in 46 CFR 162.161-6 is in accordance with requirements of the International Maritime Organization, IMO MSC/Circ.848 “Revised Guidelines for the Approval of Equivalent Fixed Gas Fire-Extinguishing Systems, as referred to in SOLAS 74, for machinery spaces and cargo pump-rooms” and IMO MSC.1/Circ. 1267 “Amendments to the Revised Guidelines for the Approval of Equivalent Fixed Gas Fire-Extinguishing Systems, as referred to in 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 (clean agent) fire suppression systems. These requirements are described throughout the regulations. They are used because we did not find voluntary consensus standards that are applicable to this rule.

    M. Environment

    We have analyzed this 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 concluded that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. This rule is categorically excluded under section 2.B.2, figure 2-1, paragraph (34) (d) of the Instruction and 6 (a) of the “Appendix to National Environmental Policy Act: Coast Guard Procedures for Categorical Exclusions, Notice of Final Agency Policy” (67 FR 48243, July 23, 2002).” This rule involves regulations concerning vessel operation safety standards and regulations concerning equipping of vessels. An environmental analysis checklist and a categorical exclusion determination are available in the docket where indicated under ADDRESSES.

    (b) The lockout valve must be a manually operated valve located in the discharge manifold prior to the stop valve or selector valves. When in the closed position, the lockout valve must provide complete isolation of the system from the protected space or spaces, making it impossible for carbon dioxide to discharge in the event of equipment failure during maintenance.

    (c) The lockout valve design or locking mechanism must make it obvious whether the valve is open or closed.

    (d) A valve is considered a lockout valve if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it.

    (e) The master or person-in-charge must ensure that the valve is locked open at all times, except while maintenance is being performed on the extinguishing system, when the valve must be locked in the closed position.

    2 On vessels contracted for prior to November 19, 1952, electric or pneumatic detecting may be substituted.
    3 On vessels contracted for prior to January 1, 1962, a steam smothering system may be accepted. However, although existing steam smothering systems may be repaired, replaced, or extended, no new system contracted for on or after January 1, 1962, will be permitted.
    4 Protection of auxiliary boilers, fuel oil units, valves, and manifolds are not required on vessels contracted for prior to November 19, 1952.
    5 Not required on vessels less than 300 gross tons (except on an international voyage) using fuel with a flashpoint higher than 110° F., where the space is normally manned.
    6 Not required on vessels contracted for prior to November 19, 1952.
    7 Not required on vessels less than 300 gross tons nor on vessels contracted for prior to November 19, 1952, except when fuel, including starting fuel, has a flashpoint of 110 °F. or less.
    8 When fuel with a flashpoint of 110 °F. or lower is used, the space containing the fuel tanks must be protected by a carbon dioxide or clean agent system as described in 46 CFR subpart 95.16.

    (h) If a vessel uses main or auxiliary oil fired boilers or internal combustion propulsion machinery, and is required to have two fire pumps, the pumps must be in separate spaces and the arrangement of pumps, sea connections, and sources of power must be arranged to ensure that a fire in any one space will not put all of the fire pumps out of operation. However, in vessels of less than 300 feet in length, when it is shown to the satisfaction of the Commandant that it is unreasonable or impracticable to meet this requirement due to the size or arrangement of the vessel, or for other reasons, the installation of a total flooding carbon dioxide or clean agent extinguishing system may be accepted as an alternate method of extinguishing any fire that affects the powering and operation of at least one of the required fire pumps.

    (b) The lockout valve must be a manually operated valve located in the discharge manifold prior to the stop valve or selector valves. When in the closed position, the lockout valve must provide complete isolation of the system from the protected space or spaces, making it impossible for carbon dioxide to discharge in the event of equipment failure during maintenance.

    (c) The lockout valve design or locking mechanism must make it obvious whether the valve is open or closed.

    (d) A valve is considered a lockout valve if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it.

    (e) The master or person-in-charge must ensure that the valve is locked open at all times, except while maintenance is being performed on the extinguishing system, when the valve must be locked in the closed position.Start Printed Page 33877

    (7) A lockout valve must be provided on any carbon dioxide extinguishing system protecting a space over 6,000 cubic feet in volume and installed or altered after [July 9, 2013. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.

    (8) The lockout valve must be a manually operated valve located in the discharge manifold prior to the stop valve or selector valves. When in the closed position, the lockout valve must provide complete isolation of the system from the protected space or spaces, making it impossible for carbon dioxide to discharge in the event of equipment failure during maintenance.

    (9) The lockout valve design or locking mechanism must make it obvious whether the valve is open or closed.

    (10) A valve is considered a lockout valve if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it.

    (11) The master or person-in-charge must ensure that the valve is locked open at all times, except while maintenance is being performed on the extinguishing system, when the valve must be locked in the closed position.
