Carbon Dioxide Fire Suppression Systems

The Coast Guard is amending the current regulations for fire suppression systems on several classes of commercial vessels including some Subchapter T charter 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.

 

[[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.

 vessels (<100 gross tons & 2 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

 

[[Page 33863]]

 

alternatives 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

 

[[Page 33864]]

 

natural 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

 

[[Page 33865]]

 

odorizers, 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.

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:

[[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

 

[[Page 33868]]

 

cause 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.

---------------------------------------------------------------------------

 

    \1\ ``Valuing Mortality Risk Reductions in Homeland Security 

Regulatory Analyses'', DHS/CBP, June 2008.

---------------------------------------------------------------------------

 

    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

 

[[Page 33869]]

 

small 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

 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.

 

[[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

Notes to Table 76.01-5(a)

\1\ Vessels of 100 gross tons and over contracted for, on, or before May 27, 1936, and having combustible joiner

  work must be fitted with an automatic sprinkling system, except in relatively incombustible spaces.

\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[deg] 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 [deg]F. or less.

\8\ When fuel with a flashpoint of 110 [deg]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.

 

    (b) The arrangements and details of the fire detecting systems must 

meet the requirements in 46 CFR subparts 76.25 through 76.33.

37. In Sec.  76.10-5, revise paragraph (h) to read as follows:

 

 

Sec.  76.10-5  Fire pumps.

 

* * * * *

    (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.

38. Add Sec.  76.15-50 to read as follows:

 

 

Sec.  76.15-50  Lockout valves.

 

    (a) 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.

    (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.

 

[[Page 33877]]

 

    (f) Lockout valves added to existing systems must be approved by 

the Commandant as part of the installed system.

39. Add Sec.  76.15-60 to read as follows:

 

 

Sec.  76.15-60  Odorizing units.

 

    Each carbon dioxide extinguishing system installed or altered after 

July 9, 2013, must have an approved odorizing unit to produce the scent 

of wintergreen, the detection of which will serve as an indication that 

carbon dioxide gas is present in a protected area and any other area 

into which the carbon dioxide may migrate. ``Altered'' means modified 

or refurbished beyond the maintenance required by the manufacturer's 

design, installation, operation and maintenance manual.

                                                      it is not, or if seal is broken, weigh or otherwise

                                                      determine that extinguisher is fully charged with foam.

                                                      Recharge if pressure is low or if foam is needed. Replace

                                                      premixed agent every 3 years.

Inert gas..........................................  Recharge or replace cylinder if cylinder pressure loss

                                                      exceeds 5 percent of the specified gauge pressure,

                                                      adjusted for temperature. Test time delays, alarms, and

                                                      ventilation shutdowns with carbon dioxide, nitrogen, or

                                                      other nonflammable gas as stated in the system

                                                      manufacturer's instruction manual. Inspect hoses for

                                                      damage or decay. Ensure that nozzles are unobstructed.

                                                      Cylinders must be tested and marked, and all flexible

                                                      connections on fixed inert extinguishers must be tested or

                                                      renewed as required by 46 CFR 147.60 and 147.66.
