Air Quality Impact Analyses (AQIA) are required in support of permit applications to demonstrate compliance with national ambient air quality standards (NAAQS), PSD increments, air quality related values (AQRV, including visibility) and other ambient criteria. We have extensive experience assessing ambient pollutant impacts from emission sources using USEPA-approved computer models, including ISCST3, CALPUFF, and AERMOD.
