{"data":{"id":"us/40-cfr-98.451","jurisdiction":"us","citation":"40 CFR 98.451","heading":"Reporting threshold.","body":"You must report GHG emissions under this subpart if your facility contains an electrical equipment manufacturing or refurbishing process and the facility meets the requirements of § 98.2(a)(2). To calculate total annual GHG emissions for comparison to the 25,000 metric ton CO2e per year emission threshold in § 98.2(a)(2), follow the requirements of § 98.2(b), with one exception. Instead of following the requirement of § 98.453 to calculate emissions from electrical equipment manufacture or refurbishment, you must calculate emissions of each fluorinated GHG that is a component of a reportable insulating gas and then sum the emissions of each fluorinated GHG resulting from manufacturing and refurbishing electrical equipment using equation SS-1 to this section.\nWhere:\nE = Annual production process emissions for threshold applicability purposes (metric tons CO2e).\nPj = Total annual purchases of reportable insulating gas j (lbs).\nGHGi,w = The weight fraction of fluorinated GHG i in reportable insulating gas j if reportable insulating gas j is a gas mixture. If not a mixture, use 1.\nGWPi = Gas-appropriate GWP as provided in table A-1 to subpart A of this part.\nEF = Emission factor for electrical transmission and distribution equipment (lbs emitted/lbs purchased). For all gases, use an emission factor of 0.1.\ni = Fluorinated GHG contained in the electrical transmission and distribution equipment.\n0.000453592 = Conversion factor from lbs to metric tons.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER C—AIR PROGRAMS","PART 98—MANDATORY GREENHOUSE GAS REPORTING","Subpart SS—Electrical Equipment Manufacture or Refurbishment"],"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":"69ee43c557462a46ec36390a7d23787b3e3937479f6d57e70026246032a6265c","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-98.450","next":"us/40-cfr-98.452"},"notice":"GroundRules: Original legal text.
