Midwest subregional modeling

Conference ·
OSTI ID:20002102
The Lake Michigan States performed subregional photochemical grid modeling in the Midwest to assess the effect of the regional NO{sub x} controls required by USEPA's recent NO{sub x} SIP call. The modeling shows that the regional (point source) NO{sub x} controls produce widespread ozone decreases. Ozone decreases occur throughout much of the modeling domain, including areas with high base concentrations. The modeled attainment tests show that Clean Air Act controls and the regional NO{sub x} controls generally show attainment of the 1-hour NAAQS. To meet the 8-hour NAAQS in all counties in the Lake Michigan area, the modeling indicates that Clean Air Act controls, the regional NO{sub x} controls, plus some additional VOC and NO{sub x} control will be needed.
