Clean Air Act
This action promulgates national emission standards for hazardous air pollutants (NESHAP) for the pesticide active ingredient (PAI) production source category under section 112 of the Clean Air Act (CAA or Act). The intent of the standards is to reduce emissions of hazardous air pollutants (HAP) from existing and new facilities that manufacture organic PAI used in herbicides, insecticides, and fungicides. The standards protect human health and the environment by reducing HAP emissions to the level corresponding to the maximum achievable control technology (MACT) through the use of pollution prevention measures and control strategies. The major HAP emitted by facilities covered by this rule include toluene, methanol, methyl chloride, and hydrogen chloride. 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 (2,755 tons per year), a reduction o f 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. The emission reductions achieved by these standards, when combined with the emission reductions achieved by other similar standards, will achieve the primary goal of the CAA, which is to "enhance the quality of the Nation's air resources so as to promote the public health and welfare and the productive capacity of its population."

The July 16, 1992 source category list included an agricultural chemicals industry group that contained 10 source categories. Today's final rule groups these 10 agricultural chemicals source categories into one source category, renames the source category, and adds additional chemical production processes to the source category.
