When calculating total dioxins/furans, zero may be used for congeners that are below the estimated detection limit (EDL). For estimated maximum possible concentration (EMPC) results, zero may be used when the EMPC is below the EDL, otherwise the EMPC must be used in determining total dioxins/furans. To demonstrate compliance for carbon monoxide, nitrogen oxides, and sulfur dioxide, see § 60.6470.","path":["Title 40—Protection of Environment","CHAPTER I—ENVIRONMENTAL PROTECTION AGENCY","SUBCHAPTER C—AIR PROGRAMS","PART 60—STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES","Subpart WWWW—Emission Guidelines and Compliance Times for Large Municipal Waste Combustors Constructed on or Before January 23, 2024"],"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":"d36c0f292ab86234a64c200502f838fe9b89af4bf775c9cc447baf269a47891d","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-60.6515","next":"us/40-cfr-60.6525"},"notice":"GroundRules: Original legal text.
