Use of Receptor and Dispersion Modeling Principles in Assessing Pre-and Post-Abatement Conditions of an Emission Source

摘要

Wind sector analyses, chemical mass balances (CMB) and dispersion modeling havebeen used to estimate the impacts of emission sources on receptor sites. The paper presents the use of these models in assessing possible changes in the ambient air impact of a biomedical waste combustor (BWC) which recently installed air pollution control devices (APCDs) as part of its air emission permit plan. Emissions inventory data for the BWC were used with the industrial source complex short-term (ISCST) dispersion model to estimate ambient air concentrations at the receptor site, which were then compared with the CMB estimates. By applying these methods at similar time frames before and after APCD installation at the BWC, it was possible to determine whether these modifications were reflected in a subsequent change in the ambient air impact on the local air shed.
