Date: 08/31/2012
Location(s): Colorado
Offices(s): Western Area Power Administration-Rocky Mountain Region

Western Area Power Administration (Western) replaced approximately 55 structures on an existing l 0 mile section of the 115-k V transmission line between Beaver Creek and Big Sandy Substations in Washington County, Colorado. The Last Chance fire which began on June 25, 2012, destroyed the existing structures beyond repair. Western crews responded to this emergency and rebuilt the downed power lines to restore electrical service. The maintenance crews used existing access roads and no grading or construction of new access occurred. Ground disturbance was limited to that associated with utility trucks operating at the replacement structure sites. Emergency work was completed on July 3, 2012.
