{"abstract":"This action lists three substitutes for ozone-depleting substances (ODSs) in the fire suppression and explosion protection sector as acceptable (subject either to narrowed use limits or use conditions) under the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) program. SNAP implements section 612 of the Clean Air Act, as amended in 1990, which requires EPA to evaluate substitutes for ODSs to reduce overall risk to human health and the environment. In this Direct Final Rulemaking (FRM), EPA is issuing its decision on the acceptability of three halon substitutes in the fire suppression and explosion protection sector. EPA is issuing a companion proposal to this direct final rule elsewhere in today's Federal Register. If we receive any adverse comments, EPA will withdraw this direct final action and will consider and respond to any comments prior to taking any new, final action.","action":"Direct final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2003/01/27/03-1623.html","cfr_references":[{"chapter":null,"citation_url":null,"part":82,"title":40}],"citation":"68 FR 4004","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective on March 28, 2003, without further notice, unless EPA receives adverse comment or receives a request for a public hearing by February 26, 2003.
