Finding of No Practicable Alternative (FONPA) for Bridge Repair near Launch Facility A-06, Cascade County, Montana
Abstract
Malmstrom Air Force Base owns and maintains a vehicle bridge that spans Belt Creek near Monarch, Montana. The bridge provides access to the Intercontinental Ballistic Missile Launch Facility A-06. During the spring of 2011, high runoff eroded areas of the northern bridge abutment and nearby streambank soils. The bridge also snagged several large trees and additional floating debris that are currently lodged on the upstream side of the bridge. In order to protect the bridge and reduce impacts to Belt Creek, it is necessary to provide repairs and permanent protection of the bridge piers, embankments, and soils in the streambanks and streambeds near the bridge. This document serves as a Finding of No Practicable Alternative (FONPA) in support of this proposed action. This FONPA was prepared in accordance with Executive Order EO) 11988, Floodplain Management, as this action proposes to repair the access bridge near Launch Facility A-06 and nearby stream bank within the 100-yr floodplain of Belt Creek in Cascade County, Montana.
