Pharmaceuticals Production Industry: National Emission Standards for Hazardous Air Pollutants (NESHAP)

Rule Summary

These national emission standards for hazardous air pollutants (NESHAP) apply to major source facilities which produce pharmaceutical products. The major HAP emitted by these facilities include methylene chloride, methanol, toluene, and hydrogen chloride. Methylene chloride is considered to be a probable human carcinogen and the other pollutants can cause noncancer health effects in humans. The promulgated rule is estimated to reduce HAP emissions from existing facilities by 22,000 megagrams per year (Mg/yr) (24,000 tons per year [tons/yr]). It also reduces volatile organic compound (VOC) emissions.
