Air Quality

GeoEngineers has a growing team of environmental scientists who specialize in air quality. They calculate emissions from point sources, model dispersion, and help clients navigate the web of federal, state and local air quality requirements. We use computer models such as AERMOD, Calpuff, CMAQ and SLAB to integrate source pollutant emission rates, meteorological data, and terrain data and estimate pollutant concentrations at downwind receptor locations. We use these models as a basis for siting ambient monitors, evaluating potential exposure for risk management plans and developing control strategies to move clients into compliance with National Ambient Air Quality Standards (NAAQS), state implementation plans, and other applicable air permits (Title V Operating Permit, PSD Construction Permit, etc.).
