Pesticide Active Ingredient Production Industry: National Emission Standards for Hazardous Air Pollutants (NESHAP)
Rule Summary
The intent of these standards is to reduce emissions of hazardous air pollutants (HAP) from existing and new facilities that manufacture organic pesticide active ingredients (PAI) used in herbicides, insecticides, and fungicides.
The major HAP emitted by these facilities include toluene, methanol, methyl chloride, and hydrogen chloride (HCl). All of these pollutants can cause reversible or irreversible toxic effects following exposure.
The rule is estimated to reduce total HAP emissions from existing facilities by 2,500 megagrams per year (Mg/yr) (2,755 tons per year (tons/yr)), a reduction of 65 percent from the baseline emission level. Because many of these pollutants are also volatile organic compounds (VOC), which are precursors to ambient ozone, the rule will aid in the reduction of tropospheric ozone.
See the regulations below for more details.
