2012-29984. 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.

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.

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.
