Establish the average operating temperature based on the performance test as specified in § 63.1185(a).\n(c) Following the performance test, measure and record the average operating temperature of the incinerator as specified in § 63.1185(b) of this subpart.\n(d) Maintain the operating temperature of the incinerator so that the average operating temperature for each three-hour block period never falls below the average temperature established during the performance test.\n(e) Operate and maintain the incinerator as specified in your operations, maintenance, and monitoring plan required by § 63.1187 of this subpart.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER C—AIR PROGRAMS","PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES","Subpart DDD—National Emission Standards for Hazardous Air Pollutants for Mineral Wool Production"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-40.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:04Z","sha256":"309bb72b5a020fb91382fbe2ef2c65b1e96cca2039b60c04cba29bb377111b6f","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-63.1181","next":"us/40-cfr-63.1183"},"notice":"GroundRules: Original legal text.
