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

摘要

The U.S. Environmental Protection Agency (EPA) is proposing to list three substitutes for ozone-depleting substances in the fire suppression and explosion protection sector as acceptable subject to use restrictions under the EPA's Significant New Alternatives Policy (SNAP) program. This program implements section 612 of the Clean Air Act, as amended in 1990, which requires EPA to evaluate substitutes for ozone-depleting substances and find them acceptable where they pose comparable or lower overall risk to human health and the environment than other available substitutes. In the "Rules and Regulations" section of this Federal Register, we are listing three fire suppression substitutes as acceptable subject to use restrictions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule; in such case, the final rule will become effective as provided in the accompanying direct final rule.
