Emergency Generator Emissions and Dispersion Modeling System Analysis
HMMH provided construction air permitting services for a new Supplemental Powerhouse at the Airbus Final Assembly Line–USA facility in Mobile, Alabama. The powerhouse adds utility capacity for aircraft assembly and painting operations at the Airbus complex.
HMMH calculated criteria pollutant emissions from the new equipment, including seven boilers, two diesel-powered fire pumps, and a cooling tower. The team identified applicable federal and state air regulations and evaluated emissions from the new powerhouse together with those from the previously permitted Central Utility Plant. This gave the design-build team a basis for addressing air permitting requirements across both utility facilities.
HMMH prepared the Minor Source Construction Air Permit application and coordinated with the Alabama Department of Environmental Management to support an expedited review. The agency issued the permit less than two months after the application was submitted.
