Section 4.13 of 45CSR7 addresses potential hazardous material emissions. This section requires that the
utmost care and consideration of potential harmful effects from air emissions be evaluated from
manufacturing process source operations that emit hazardous particulate matter. These compounds include, but
are not limited to lead, arsenic, beryllium, asbestos and mercury (these compounds happen to have plantwide
de minimus thresholds established in Table 45-13A of 45CSR13). The DAQ is required to make these evaluations
based on the adequacy, efficiency and emission potential of these facilities, while working in conjunction
with other appropriate governmental agencies.
