Unified Emission Factors (pdf)  
Preferred method for estimating emissions of Styrene and Methyl Methacrylate from open molding of resin composites including the Boat Manufacturing Industry but not the Reinforced Plastic Composites Industries covered by 40 CFR 63, Subpart WWWW.

MACT Final Rule for Reinforced Plastic Composite Production (40 CFR 63, Subpart WWWW) 
Preferred method for estimating emissions from these facilities. (Note: For the purpose of Emission Inventories, all processes at your facility should have emissions estimated including those that may be exempted from this Emission Standard.) (If your process differs from those described in this document use above Unified Emission Factors for estimating emissions.)

Catalyst Used in the Open Molding of Composites (pdf)  
Preferred method of estimating emissions from catalyst used in resin composites.

Polyurethane Foam  
Emission estimation assistance for Diphenyl Methane Diisocyanate (MDI) emissions from polyurethane foam

Catalyst Used in the Non-Open Molding of Composites (pdf)
