The COB Energy Facility would be constructed on a site near the rural community of Bonanza, in Klamath County, Oregon. Generating components of the project would be constructed in either one or two phases, including four air-cooled combustion turbine generators fueled with natural gas, four heat recovery steam generators, and two steam turbines. Additional facilities include a new 7.2-mile-long 500-kV transmission line, a new 4.1-mile-long natural gas pipeline, a 2.8-mile-long water pipeline, a 20-acre wastewater evaporation pond or a 3,770-foot-long irrigation pipeline to deliver wastewater to a 31-acre pasture, a 4.7-acre stormwater infiltration basin, a 1.5-acre stormwater retention pond, and various tanks, buildings, exhaust stacks, parking, and storage areas. Natural gas to fuel the combustion turbines would be supplied by way of a new 4.1-mile-long, 20-inch-diameter pipeline from a Gas Transmission Northwest's Bonanza Compressor Station. The new pipeline would be constructed within private easements adjacent to or near Klamath County road rights-of-way. Although COB Energy Facility generators would use air-cooled condensers, the project would use an average of 72 gallons per minute for steam production and station service, up to a maximum of 210 gallons per minute. The source of this water would be one existing and two new wells near the project site, drawing from a deep aquifer consistent with a State of Oregon water right permit expected to be incorporated into the State energy facility site certificate. Process wastewater would either be used to irrigate pasture or held in a lined pond to evaporate. Sanitary water would be routed to an onsite septic tank then discharged to a leach field. No wastewater would be discharged to surface waters. The COB Energy Facility would interconnect to the FCRTS at Captain Jack Substation, 7.2 miles south of the project site. PERC would construct a new 500-kV transmission line from the project site to Captain Jack Substation. Part of the transmission line would cross public land managed by the Bureau of Land Management. BPA would install additional electrical equipment at Captain Jack Substation. At this time, PERC has not requested specific points of delivery.
