摘要

The implementation of the strategy for reduction of pollutant emissions has resulted in reduced ambient concentrations of TSP and SO2. Current levels of air quality in the study area, however, indicate that progress has not been sufficient to attain the NAAQS. At present, it is not known whether the problem lies in lack of strict enforcement of the SIP or whether the SIP is in itself insufficient. In order to make this determination, the State of Indiana initiated a review of the current SIP. Radian Corporation was retained to perform an update of the area source portion of the review. The update was designed to determine the area source emissions at a level of accuracy consistent with the higher level of detail described in the Guidelines for Air Quality Maintenance Planning and Analysis. To determine if problems will be encountered in maintaining air quality standards in the future, area and point source emissions were projected for the years 1975, 1980, and 1985.
