If a PTE does not exist, then a temporary total enclosure must be constructed and verified using EPA Method 204, and capture efficiency testing must be determined using EPA Methods 204B through E of appendix M to 40 CFR part 51.\n(b) The capture efficiency of an oven is to be considered 100 percent, provided the oven is operated under negative pressure.","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 WWWW—National Emissions Standards for Hazardous Air Pollutants: Reinforced Plastic Composites 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":"4774ceadf9c8f04bd4a8298c047f74370392d763638e919900c81d47a38d6f3b","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-63.5870","next":"us/40-cfr-63.5880"},"notice":"GroundRules: Original legal text.
