The principal impacts associated with the beddown are related to the operational characteristics of the E-3A aircraft in terms of noise and engine emissions. Noise from aircraft operations by 1981 may contribute to an additional 549 acres of incompatible land use. An additional 7,234 inhabitants and 2,042 housing units may be located in areas around Tinker AFB considered incompatible according to AICUZ criteria. The increase in air pollutant emissions by 1981 resulting from AWACS will be equivalent to approximately 0.5 percent or less of the regional emissions reported for 1970. Increases impede, to some degree, efforts to control concentrations of these pollutants which are already exceeding standards established for the region.
