Air Quality Permitting: We have extensive experience preparing Prevention of Significant Deterioration (PSD) construction permit applications, Title V initial and renewal operating applications, synthetic minor source, and minor source applications in various states throughout the United States. These permitting actions have included air dispersion modeling analyses and control technology reviews.
Air Quality Regulatory Analyses: Our air quality professionals have far-reaching experience with various federal and state regulations and pending regulations. We apply that knowledge to help our customers plan capital projects and long-term budgets.
Air Quality Compliance: We apply our expert knowledge of federal, state, and local air quality regulations when partnering with customers to develop compliance strategies.
Air Dispersion Modeling: We apply our expert knowledge of federal and state modeling requirements to demonstrate compliance with the National Ambient Air Quality Standards and state air quality standards. This modeling is conducted in accordance with Appendix W utilizing AERMOD. Our professionals have utilized Tier I, Tier II, and Tier III methodologies such as ARM2, PVMRM, and OLM to demonstrate compliance with the 1-hr NO2 standard.
Air Quality Emissions Inventories: Our air quality professionals have decades of experience preparing emission inventories for facilities from general manufacturing to refineries to oil and gas operations.
Air Quality Greenhouse Gas Support: We use our process expertise to help facilities prepare greenhouse gas monitoring plans and estimate emissions for the Mandatory Reporting Rule.
Toxic Release Inventories: Our process expertise is used to help facilities evaluate facility operations to determine Toxic Release Inventory applicability and prepare the Form A or Form R reports.
