On December 7, 1995, the . EPA promulgated a National Emission Standard for Hazardous Air Pollutants (NESHAP) for the wood furniture manufacturing industry. The NESHAP applies to all wood furniture manufacturers with the potential to emit 10 tons per year (tpy) or more of a single HAP or 25 tpy or more of a combination of HAPs. Potential to emit is defined and discussed in Section of this Manual. Existing sources emitting 50 tpy or more of HAPs are required to comply with these new federal regulations by November 21, 1997; sources emitting below 50 tpy HAPs have an extended compliance date.
