Carbon Dioxide Fire Suppression Systems on Commercial Vessels

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.

[[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:

* These are average unit costs for lockout valves. Final rule unit cost estimates for odorizers did not change
  since the NPRM.

[[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

    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.

Sec.  34.15-50  Lockout valves--T/ALL.

    (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.
    (f) Lockout valves added to existing systems must be approved by 
the Commandant as part of the installed system.

18. Add Sec.  34.15-60 to read as follows:

Sec.  34.15-60  Odorizing units--T/ALL.

    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.

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.

0
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.

0
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.

0
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.

    (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.

    (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.
    (i) 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.
    (ii) The lockout valve design or locking mechanism must make it 
obvious whether the valve is open or closed.
    (iii) 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.
    (iv) 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.
    (v) Lockout valves added to existing systems must be approved by 
the Commandant as part of the installed system.
    (8) 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

and the arrangement, pumps, sea connections, and sources of power must 
be such as to ensure that a fire in any one space will not put all of 
the fire pumps out of operation. However, 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 system using 
carbon dioxide or a clean agent complying with 46 CFR subpart 95.16 may 
be accepted as an alternate method of extinguishing any fire that could

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.
    (f) Lockout valves added to existing systems must be approved by 
the Commandant as part of the installed system.

Sec.  193.15-17  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.
