Western Area Power Administration (WAPA) proposes to conduct routine maintenance to structures on its Long House Valley - Kayenta (LHV-KAY) and Kayenta - Shiprock (KAY-SHR) 230-kV Transmission Lines located on Navajo Tribal Trust Lands in Navajo County, Arizona. Structures 74/5 and 77/1 on the LHV-KAY Transmission Line and Structures 88/3 and 89/2 on the KAY-SHR Transmission Line require maintenance to clean-out and remove accumulated sand, sediment and vegetation from around the steel lattice footers and from inside the structure footprint. Due to the shifting soils along both Transmission Lines, this maintenance is needed to help maintain the overall stability and longevity of the structures. Equipment utilized for structure maintenance would include track dozer, backhoe, skid-steer loader, utility trucks and other rubber-treaded vehicles. To access the work areas, maintenance crews will use existing access roads. No road maintenance activities are authorized as part of this Categorical Exclusion (CX).
