This EA has been prepared in accordance with the National Environmental Policy Act NEPA. The analysis focused on the following environmental resources airspace management and air traffic control, noise, safety, air quality hazardous materials and waste management, biological resources, cultural resources, land use, socioeconomics, and environmental justice. Airspace management would not be impacted by the additional six primary F-22 aircraft. Additional portions of the Knik Arm, the Port of Anchorage, and land west of the Knik Arm would experience noise levels of 65 decibels dB Day-Night Average Sound Level Ldn or greater, but this change is not projected to significantly impact any human or natural resources, including threatened or endangered species. On February 22, 2011, the National Marine Fisheries Service evaluated the potential consequences and issued a finding of may affect but not likely to adversely affect Cook Inlet beluga whales. There would be no construction required. Hence, there would be no construction noise, no construction air emissions and no impacts to JBER cultural resources. Any hazardous materials associated with aircraft would be handled in the existing specialized F-22 maintenance facility and controlled to protect air and water resources. An increase of 103 base positions less than one percent of base employment is not expected to substantially affect commute times and would result in no measurable effect upon the regional economy. No on- or off-base residences are exposed to noise levels greater than 80 dB Ldn. Workers on JBER are protected against possible noise impacts by adherence to DoD noise management guidelines. The 65 dB Ldn noise contours would not extend off base over residential areas. Disadvantaged populations would not be disproportionately affected by the proposed plus-up, and there would be no health or safety impacts to children.
