Class II Air Dispersion Modeling
A major steel manufacturing facility in Alabama was undergoing a significant capacity expansion. Our team modeled emissions from multiple new and modified sources using EPA's AERMOD modeling system, incorporating site-specific meteorological data, complex terrain features, and nearby source interactions.
Steps to Success:
- We evaluated impacts against all applicable National Ambient Air Quality Standards (NAAQS) and Prevention of Significant Deterioration (PSD) increments.
- We demonstrated compliance across all pollutants and averaging periods.
- We supported a successful PSD permit approval with no modeling-related conditions or delays.
