40 CFR Part 82

[EPA-HQ-OAR-2011-0111; FRL-9757-5]
RIN 2060-AQ84

Protection of Stratospheric Ozone: Listing of Substitutes for 
Ozone Depleting Substances--Fire Suppression and Explosion Protection

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal in part of direct final rule.

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

SUMMARY: On September 19, 2012, the Federal Register published a direct 
final rule and a companion proposed rule issuing listings for three 
fire suppressants under EPA's Significant New Alternatives Policy 
program. Because EPA received adverse comment concerning C7 
Fluoroketone, we are withdrawing that part of the direct final rule 
that listed C7 Fluoroketone acceptable subject to narrowed use limits 
as a substitute for halon 1211. Other listings in that direct final 
rule will take effect on December 18, 2012.

DATES: Effective December 14, 2012, EPA withdraws the entire entry for 
``Streaming: C7 Fluoroketone as a substitute for Halon 1211'' in 
Appendix S to Subpart G of Part 82 in the direct final rule published 
at 77 FR 58035, September 19, 2012.

FOR FURTHER INFORMATION CONTACT: Bella Maranion, Stratospheric 
Protection Division, Office of Atmospheric Programs; Environmental 
Protection Agency, Mail Code 6205J, 1200 Pennsylvania Avenue NW., 
Washington DC 20460; telephone number (202) 343-9749, fax number, (202) 
343-2338; email address at maranion.bella@epa.gov. The published 
versions of notices and rulemakings under the SNAP program are 
available on EPA's Stratospheric Ozone Web site at http://www.epa.gov/ozone/snap/regs.

SUPPLEMENTARY INFORMATION: On September 19, 2012, the Federal Register 
published a direct final rule and a companion proposed rule issuing 
listings for three fire suppressants under EPA's Significant New 
Alternatives Policy program (77 FR 58035). Because EPA received adverse 
comment concerning C7 Fluoroketone, we are withdrawing that part of the 
direct final rule that listed C7 Fluoroketone.
    The listing would have found C7 Fluoroketone acceptable subject to 
narrowed use limits, as a substitute for halon 1211 for use as a 
streaming agent in portable fire extinguishers in nonresidential 
applications. We stated in that direct final rule that if we received 
adverse comment by October 19, 2012, that we would publish a timely 
withdrawal in the Federal Register. We subsequently received one 
adverse comment on that part of the direct final rule, but no comments 
on the other listings in the direct final rule. The other listings in 
that direct final rule, finding Powdered Aerosol F and Powdered Aerosol 
G acceptable subject to use conditions as substitutes for halon 1301 
for use as a total flooding agent in normally unoccupied areas, will 
take effect on December 18, 2012. EPA intends to address the adverse 
comment concerning C7 Fluoroketone in a subsequent final action, which 
will be based on the parallel proposed rule published on September 19, 
2012 (77 FR 58081). As stated in the direct final rule and the parallel 
proposed rule, we will not institute a second comment period on this 
action.

    Dated: December 5, 2012.
Gina McCarthy,
Assistant Administrator, Office of Air and Radiation.
    Accordingly, the entire entry for ``Streaming: C7 Fluoroketone as a 
substitute for Halon 1211'' in Appendix S to Subpart G of Part 82 in 
the direct final rule published on September 19, 2012 (77 FR 58035) is 
withdrawn as of December 14, 2012.
