Characterization of PM 10 and TSP (Total Suspended Particulate) Air Quality Around Western Surface Coal Mines

摘要

This document is directed to those managers and technical staff of coal industry and air pollution regulatory agencies needing information on the general impact of surface mines on ambient particulate matter concentrations. The document addresses both PM(10), which is a measure of particles generally smaller than 10 micrometers by a sampler with a 50% efficiency at 10 micrometers, and Total Suspended Particulate (TSP), as measured by a high volume sampler. Estimates of PM(10) and TSP concentrations are developed from actual measurements, from previous dispersion modeling and from modeling three scenarios representing a range of mine sizes and configurations. The results are compared to the Prevention of Significant Deterioration (PSD) regulations and the National Ambient Air Quality Standards (NAAQS). Both maximum controls and typical controls are considered, and distances from mine boundaries where PSD and/or NAAQS are exceeded are discussed.
