COB Energy Facility, LLC, a subsidiary of Peoples Energy Resources Corporation (PERC), proposes to construct a natural gas-fired, combined-cycle electric generating plant near Bonanza, Oregon. The Energy Facility would have a nominal generation capacity of 1,160 megawatts (MW). Electric power from the Energy Facility would enter the regional grid at the Bonneville Power Administration's (BPA's) Captain Jack Substation via a proposed 7.2-mile electric transmission line. BPA must decide whether to grant the interconnection required to connect this proposed transmission line to the Captain Jack Substation. In addition, the proposed transmission line would cross some Federal lands. The Bureau of Land Management (BLM) must decide whether to grant the necessary rights-of-way for the transmission line on approximately 44 acres of BLM land. Accordingly, BPA as the lead agency and BLM as the cooperating agency have prepared this environmental impact statement (EIS) to fulfill the requirements of the National Environmental Policy Act (NEPA). Electrical consumers in the Pacific Northwest and western states need increased power generation to serve increasing demand, and high-voltage transmission service to deliver that power. BPA will grant the interconnection if it will help to provide an adequate and reliable power supply for the region, consistent with BPA's environmental, social, and economic responsibilities. BPA intends to act consistently with its Open Access Transmission Tariff in considering the interconnection request. BLM will grant the rights-of-way if they will authorize appropriate uses of public land consistent with applicable planning documents.
