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.
