Evaluation of Airport Emissions within State Implementation Plans

More than 150 of the nation's commercial service airports are located in EPA-designated nonattainment or maintenance areas for one or more criteria pollutants designated by the U.S. Environmental Protection Agency. Federal funding or approvals of future airport development at these facilities may be affected by policies and regulations contained in the State Implementation Plan (SIP), now required by the Clean Air Act Amendments of 1990. The SIP outlines a plan to reduce pollutant emissions and concentrations, bringing nonattainment and maintenance areas into compliance with national standards.

ESA is collaborating in the development of a guidebook for airport operators and state and local air quality planners that describes the development of the airport emissions inventories for inclusion in SIP documents. We are assisting with the research and analysis that will assist airports and state and local air quality agencies in better representing airport emissions sources in their SIP emissions budgets. The guidebook will include guidance on how to develop airport emissions inventories, and direction on how to harmonize future airport emissions estimates with aviation forecasting protocols.

ESA's research and coordination of the guidebook will be a useful tool to help civilian commercial service and general aviation airports to quantify and reduce harmful pollutants and emissions, ultimately enabling the aviation industry to become more sustainable and environmentally friendly.
