Aviation continues to be a growth industry in the United States, and this growth has resulted in an increase in traffic at the nation's major airports accompanied by a corresponding increase in emissions. In addition, as EPA's emission control strategies for other non-aviation sectors take effect, aviation emissions sources could become more pronounced and, as a result, a more significant component of future SIPs. Regulations require that all federal actions be in conformance with applicable SIPs, with the understanding that non-conformance could affect the potential for federal funding of future airport development projects. Improving the ability to generate airport emissions inventories may help improve the process of preparing SIPs and aid in the consideration of future airport improvements. Guidebook users will find the information particularly useful as they prepare these airport-related emissions inventories for incorporation into SIPs. The proposed procedures apply to airports of every size (small, medium, large) and function (commercial, GA) and to users of every skill level. This Guidebook and accompanying Airport Emissions Estimator Tool can help to assure users that their airport emissions inventories are up to date and in a form that is appropriate for SIPs. As a result, both airports and regulatory agencies will benefit. |
