Description:

Wind sector analyses, chemical mass balances (CMB) and dispersion modeling have been used to estimate the impacts of emission sources on receptor sites. his 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 (APCDA) as part of its air emission permit plan. wo sets of 12-hour ambient air measurements for fine particulate matter and acid gases, acquired from a Versatile Air Pollution Sampler (VAPS), and meteorological measurements were obtained from a site in the immediate vicinity of the BWC. hese two data sets were acquired for the same time frame during two consecutive years with one year being measurements recorded before the source installed APCDA and the other year with the subsequent modifications. rom this data, pollutant rose plots of BWC tracers were generated and CMB receptor modeling was performed to ascertain the possible impacts of the BWC and other, local area sources at the site from different wind directions. missions 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. y 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.
