Abstract:
In the present research work, an environmental policy procedure for setting a cap on emissions, as a crucial step in any total emission control system, has been provided and evaluated. It is shown that general regulations on emission intensities and rates do not guarantee that ambient air quality standards are met in intense industrial zones. Local emission limits are necessary to meet ambient air quality standards in these zones. To that end, we used dispersion simulators to back-calculate pollutant concentration thresholds for a large and intense energy system in the Assaluyeh region of southern Iran. Verified modeling results indicate 218 d of pollutant concentration threshold exceedance in Assaluyeh in a simulated year. Back-calculation to assess the total permissible emission level indicates the need for 68% reduction in total emission to meet ambient air quality standards. We then used the model to help identify effective control strategies, including emission reductions and appropriate timing of specific operations.
