This EA has been prepared in accordance with the National Environmental Policy Act NEPA. Specific environmental resources associated with Elmendorf AFB with the potential for environmental consequences considered in this EA include noise, safety, air quality, physical resources, biological resources, cultural resources land use and transportation, socioeconomics, and environmental justice. Under the Proposed Action, there would be no change in noise contours or sound levels beyond those for currently scheduled aircraft. Mining operations would continue in the airfield accident potential zone, which is a permitted industrial action within this area. Combustion engine and fugitive dust emissions would produce localized, short-term elevated air pollutant concentrations but would remain within confines of construction and operating permits. The expansion area does not contain wetlands or floodplains. Expansion would result in removal of trees and productive moose browse. Gravel pit reclamation would re-establish moose browse areas. Wildlife corridors along major roadways would be protected. The proposed expansion would not affect any environmental clean-up sites. Nine archeological sites lie within the proposed expansion area. As specified in the Integrated Cultural Resources Management Plan, State Historic Preservation Office consultation would be completed, and an archeological survey would be conducted of the proposed area. Future land uses would be affected since construction potential in the reclaimed area would be limited however, the area is located within the accident potential zone, which places constraints upon land uses. There would be no effects on transportation. The proposal would not change long-term base employment or expenditures. In addition, the actions as proposed would not disproportionately impact minority and low-income populations or children. The Proposed Action would have an irreversible and irretrievable effect upon the gravel resource.
