Finding of No Significant Impact (FONSI) For Demolition of Buildings 113, 130, 140, 141, 256, 257, and the Boresight Tower at New Boston Air Force Station, New Hampshire.

摘要

The proposed action evaluated in this environmental assessment (EA) is the demolition of Building 113 (radio equipment shelter), Building 130 (former waste water treatment plant) Building 140 (generator shelter), West wing of Building 141 (former Logistics building) Building 256 (fuel vault), Building 257 (fueling station), the Boresight Tower, removal of associated infrastructure and the addition of 500 square feet of pavement adjacent to Building 134. The action could start during late 2010 or spring of 2011 and should conclude by 2012. The proposed action is needed to eliminate operation and maintenance costs for unnecessary structures on New Boston Air Force Station (NBAFS). Four other alternatives were evaluated including: Alternative 2, complete demolition of Building 141 leaving pavements, Alternative 3 demolition of Building 141 and construction of a new building, Alternative 4, repair of Building 141 and Alternative 5 no action (i.e., maintain buildings). This EA evaluated the potential impacts to air quality, noise levels, topography, geology, soils, water resources, ecological resources, cultural resources, land use, recreation, visual resources, socioeconomics, and health and safety. On the basis of this assessment, it was determined that the proposed action would result in only minor to negligible localized, short-term, or temporary impacts to the environment as compared to alternatives 2-5. The demolition of Buildings 113, 130, 141 (West wing), 256 257, and the Boresight Tower would result in a negligible to minor incremental addition to impacts that have occurred from other construction activities in the vicinity of NBAFS and would create and adverse effect to a contributing element to the NBAFS Cold War Historic District.
