Reinforced Plastics Composite Manufacturing -  Subpart WWWW

Applicability: eCFR Subpart WWWW [ecfr.gov]

This subpart applies to:
  1. Reinforced plastic composites production facilities at Major Sources* of HAPs that use thermoset resins or gel coats containing styrene.
  2. Any associated cleaning, mixing, HAP-containing materials storage, or repair operations.
Not subject to this subpart:
  1. Facilities used only for repair. This includes the non-routine manufacture of individual parts or components intended to repair larger items.
  2. Research and development facilities as defined in section 112 (c)(7) of the Clean Air Act.
  3. Facilities that use less than 1.2 tons per year combined of resins and gel coats containing styrene.
  4. Sources subject to NESHAP VVVV.
*Major Sources emit or have the potential to emit:
  • > 10 tons per year of a single HAP, or
  • > 25 tons per year combined HAPs.
  • Area Sources emit less than Major Sources.
Rules apply to small, area sources? No
