Production resin, tooling resin a. Atomized 0.014 × (Resin HAP%)2.425\nb. Atomized, plus vacuum bagging with roll-out 0.01185 × (Resin HAP%)2.425\nc. Atomized, plus vacuum bagging without roll-out 0.00945 × (Resin HAP%)2.425\nd. Nonatomized 0.014 × (Resin HAP%)2.275\ne. Nonatomized, plus vaccum bagging with roll-out 0.0110 × (Resin HAP%)2.275\nf. Nonatomized, plus vacuum bagging without roll-out 0.0076 × (Resin HAP%)2.275\n2. Pigmented gel coat, clear gel coat, tooling gel coat All methods 0.445 × (Gel coat HAP%)1.675\n1 Equations calculate MACT model point value in kilograms of organic HAP per megagrams of resin or gel coat applied. The equations for vacuum bagging with roll-out are applicable when a facility rolls out the applied resin and fabric prior to applying the vacuum bagging materials. The equations for vacuum bagging without roll-out are applicable when a facility applies the vacuum bagging materials immediately after resin application without rolling out the resin and fabric. HAP% = organic HAP content as supplied, expressed as a weight-percent value between 0 and 100 percent.","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 VVVV—National Emission Standards for Hazardous Air Pollutants for Boat Manufacturing"],"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":"16d2f79adc54dfbe322ba2614aa72b294a055345d964b1c8439101a3b6f60e38","source_id":"us-cfr","stale":true,"prev":"us/40-cfr-table-2-to-subpart-vvvv-of-part-63","next":"us/40-cfr-table-4-to-subpart-vvvv-of-part-63"},"notice":"GroundRules: Original legal text.
