Facilities Minor Activity Review Project (Tier 1). Install steel tower structures in 3G and 33S areas. Three towers in the 30G area and 1 tower in the 33S area. Towers will have high voltage switches in order to isolate sections of 115 kV line if required for maintenance. Towers will require 6 feet by 25 feet holes to be drilled; towers will then be set in the holes and backfilled with concrete; all proposed towers will be located within existing, previously disturbed areas.
