Consulting / Permitting

consulting permitting articleAQS provides consulting services to ensure that our clients establish and maintain air-related environmental compliance. Our experience, expertise, and innovative personnel provide our clients with the resources necessary to navigate the complex regulatory "terrain".


Construction or expansion of an industrial facility, or modification of operations will likely trigger air quality permitting requirements. Federal permitting programs such as Title V and PSD/NSR (including BACT and LAER determinations) can include emissions inventories, GEP evaluations, air quality analyses (including dispersion modeling, ambient air quality & meteorological monitoring), and regulatory applicability analysis.

We have successfully completed hundreds of permit applications ranging from single-source Registrations through Title V/PSD in both utility and industrial sectors.
