Final Environmental Assessment for Proposed Infrastructure to Support East Airfield Expansion, Hill Air Force Base. Utah
Abstract
Hill AFB proposes to accommodate current USAF missions by constructing power transmission facilities and vehicular access to the C-130 hangar area on Hill AFB. The proposed action includes all work necessary to develop power transmission facilities and vehicular access to the C-130 hangar area on Hill AFB. The power transmission facilities would consist of an above ground power line, a substation, and a buried power line. The vehicular access would consist of widening an existing 2-lane section of road and moving an existing fence; constructing new roadway and fence; and constructing a guard shack for a new east gate on Hill AFB. The power facilities would require less than 0.2 acres of ground disturbance (4,000 linear feet of trench at a width of 3 feet or less, and under I ,000 square feet for the substation pads). The road and guard shack would disturb approximately 7 acres (5,000 linear feet at an assumed width of 60 feet, and the guard shack to reside within the same footprint). Power poles would be installed with augers, and fencing would be installed using either augers or slide hammers. The deepest point of excavation would be 10 feet bgs at the location of the power pole to be placed adjacent to the substation. The remainder of the facilities would be constructed by excavating 7 feet of soil or less. While open. the sides of any excavations would be sloped at 1.5 horizontal to 1.0 vertical or other such angle as approved by the design and geotechnical engineering contractors. The construction contractor would restore all impacted surfaces to their original condition.
