Air Emission Permitting and Compliance Evaluations

Geosyntec air practitioners have experience across the United States providing permitting assistance to our clients under federal, state, and local air construction and operating permit programs. We have a proven track record of crafting strategic approaches to air permitting that often result in the avoidance of major source permitting requirements, like Prevention of Significant Deterioration (PSD) or non-attainment area New Source Review.

Clean Air Act (CAA) regulations have been a focus area for U.S. Environmental Protection Agency's regulatory agenda over the past few years. Without change in this emphasis, CAA regulations will continue to be in flux, with existing rules being revised and new rules being promulgated at a rate that makes compliance all the more challenging. Our air practitioners' experiential understanding of policy, regulation, and drivers results in effective and efficient compliance solutions for our clients.

Working with clients, Geosyntec practitioners provide the necessary framework to implement comprehensive environmental management strategies that allow facilities to meet compliance requirements. Among the compliance programs we have helped design include those governing emission inventory reporting, Title V annual and semi-annual reporting, greenhouse gas (GHG) reporting, and deviation reporting.

These projects include new facility permits, permit modifications, and permit renewals as well as determinations of Best Available Control Technology (BACT) and Lowest Achievable Emission Controls (LAER). We routinely conduct regulatory applicability determinations for NSR/PSD, New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAPs), Maximum Achievable Control Technology (MACT), Reasonably Available Control Technology (RACT), and state-specific requirements.
