The action evaluated in this Environmental Impact Statement (EIS) is the realignment of Cannon Air Force Base, New Mexico. The realignment is the result of the recommendations of the Defense Secretary's Commission on Base Realignment and Closure, from legislative requirements in the Base Realignment and Closure Act (Public Law 100-526), and of U.S. Air Force plans to enhance mission readiness and national security. The realignment of Cannon Air Force Base will involve the transfer of aircraft with the net result that the number of F-111s at the Base will increase by 46 planes. The associated increase in personnel will be from the current level of 3984 to 5723. The numbers of sorties and flying hours are expected to essentially double for a total of 16,500 sorties and 36,000 flying hours per year. All of these flight operations will be at subsonic speeds. In order to maintain operational efficiency and combat readiness under this realignment, on-Base military construction, creation of a new Mount Dora Military Operations Area, continued full use of the Pecos Military Operations Area, increased use of the Melrose Range, increased use of Military Training Routes, and increased aircraft operations at the Base are proposed. Off-Base flight operations will be over low population areas. Provisions of the Act preclude the examination of any alternative actions to realignment. (SDW).
