EEG’s environmental compliance and construction expertise helped PacifiCorp engineer, procure and construct (EPC) a 31-mile 345-kV transmission line, 68-mile 500-kV line, and approximately 500 structures to link the Clover Substation in Mona, Utah, with the Oquirrh Substation near West Jordan, Utah.
The transmission project straddled environmentally sensitive areas owned variously by the Bureau of Land Management (BLM), State of Utah and private parties. PacifiCorp called on EEG’s experts to work with the BLM and create and launch conservation measures to keep construction of the transmission line and substations moving, while protecting a special-status wildlife and plants habitat, wetlands and riparian areas. As part of its plan, EEG also had to consider how to control noxious weeds and navigate terrain encompassed by the Kennecott Utah Copper Corporation’s Bingham Canyon Mine, the deepest open-pit mine in the world and a designated National Historic Landmark.
EEG communicated with BLM to create a plan for construction in this area by relying on helicopters and on foot.
