This paper describes mobile source hazardous air pollutant (HAP) emissions in the Seattle-Tacoma, Washington, urban area. Included in this inventory are mobile source emissions from both on-road (e.g., highway vehicles) and non-road (e.g., agricultural equipment) mobile sources. These mobile source emission estimates, summarized in this paper, were developed based on volatile organic compound (VOC) emissions and activity level data from the Seattle-Tacoma 1990 base year State Implementation Plan (SIP) emission inventory. The contribution of mobile source HAP emissions was compared to that of stationary area sources in the Seattle-Tacoma area. Mobile sources contributed about 83% of the benzene, 74% of the formaldehyde, and 88% of the 1,3-butadiene emissions.
