Description:

The paper reports EPA/AEERL's progress on emissions inventory evaluation and improvement under a hazardous air pollutant (HAP) emissions research program in support of the Urban Area Source Program required under Title III of the Clean Air Act Amendments of 1990 (CAAA). he paper summarizes results of three current projects and indicates HAP emissions inventory needs. AP inventories for three urban areas--Chicago, San Francisco, and Seattle/Tacoma--were analyzed to identify area sources as defined in the CAAA. ne inventory focused on area sources; the other two were basically point source inventories that had facilities that met the area source definition. he HAPs that contribute most of the area source emissions in each inventory were identified, and 22 HAPs that were common to the inventories were selected for further analysis. ost are organic compounds. he source categories that emit these 22 HAPs were then identified; dry cleaning, degreasing, and surface coating were the highest emitting area sources of these pollutants. he CAAA require identification of 30 or more HAPs emitted by area sources which pose the "greatest threat to public health in the largest number of urban areas, " and the regulation of area sources accounting for 90% or more of each of these pollutants.
