| Abstract |
The report gives final results of a study of the effect of two point source NOx control strategies in the Chicago Air Quality Control Region (AQCR): combustion modification and flue gas treatment. The study involved the dispersion modeling of essentially all point and area sources of NOx in the AQCR. Gaussian type dispersion models were used for nonreactive pollutants. The model results were adjusted empirically for atmospheric conversion of NO to NO2. Two averaging times were considered: annual, corresponding to the present National Ambient Air Quality Standard (NAAQS) for NO2; and 1-hour, corresponding to the anticipated new short-term NAAQS for NO2. Results of the annual modeling indicate that large point sources are not major contributors to annual average NO2 levels. However, results of the short-term modeling indicate that large point sources can be important contributors to 1-hour average NO2 levels under certain meteorological conditions. Therefore, the control of large point source emissions can result in significant improvements in short-term NO2 air quality. |
