Start Preamble


Bureau of Indian Affairs, Interior.




This notice advises the public that the Bureau of Indian Affairs (BIA), with the cooperation of the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), intends to gather the information necessary for preparing an Environmental Impact Statement (EIS) for the proposed lease to Wanapa Energy Center of up to 195 acres of land held in trust by the United States for the benefit of the CTUIR in Umatilla County, Oregon. The Williams Energy Marketing and Trading Company, CTUIR, the Eugene Water and Electric Board, the City of Hermiston and the Port of Umatilla intend to jointly build and operate the Wanapa Energy Center, an approximately 1,300 megawatt electric generation plant, on the property. The purpose of the proposed project is to conjointly help provide for the economic development of the CTUIR and for the power needs of the Pacific northwest. Details on the proposed project and its location are provided in the SUPPLEMENTARY INFORMATION section. This notice also announces public scoping meetings to identify potential issues for inclusion in the EIS, distinguish those to be analyzed in depth, and eliminate from consideration those that are not significant.


Written comments on the scope and implementation of this proposal must arrive by November 21, 2001. The public scoping meetings will be held on November 5, 2001, and November 6, 2001, from 5 to 8 p.m.


You may mail or hand carry written comments to Philip Sanchez, Superintendent, Bureau of Indian Affairs, Umatilla Agency, P.O. Box 520, Pendleton, Oregon 97801.

The November 5, 2001, public hearing will be in Pendleton, Oregon. The November 6, 2001, public hearing will be in Hermiston, Oregon. Exact locations of the hearings will be determined at a later date and can be obtained from the FURTHER INFORMATION CONTACT listed below.

If you would like a map displaying the proposed project location, please contact Jerry L. Lauer, Natural Resource Officer, at the above Umatilla Agency address, telephone (541) 278-3790, or e-mail

The EIS will assess the environmental consequences of BIA approval of a proposed lease between Wanapa Energy Center, the lessee, and the CTUIR, the lessor, of part of Lots 1, 2, 3, and 4, the South Half of the Southwest Quarter, Section 7, Township 5 North, Range 29 East, Willamette Meridian, Umatilla County, Oregon. The property lies in western Umatilla County near McNary Dam on the Columbia River. The parties developing the Wanapa Energy Center plan to construct and operate the facility on this property.

The proposed project has several components. They include an electrical connection at or near the Bonneville Power Administration's McNary Substation; a natural gas-fired, combined cycle, combustion turbine electric generation plant; a natural gas supply pipeline; a water supply pipeline; and a new electric power transmission line. All proposed facilities would be located within Umatilla County, Oregon.

The proposed Wanapa Energy Center would be a combustion turbine, combined cycle electric power plant with a nominal generating capacity of 1,300 megawatts. It would consist of four essentially identical combustion turbine generators, four heat recovery steam generators (HRSG) and two steam turbines. Expanding gasses from combustion would turn rotors within the turbines that are connected to electric generators. The hot gases exhausted from the combustion turbines would be used to raise steam in the HRSGs. Steam from the HRSGs would be expanded through steam turbines that drive their own electric generators. The combustion turbines would be fueled by natural gas from either the existing Williams pipeline or an existing PGT pipeline. The facility would interconnect in either case through a new, approximately ten mile gas supply lateral.

Water to generate steam and cool the steam process at the plant would be supplied from the Port of Umatilla Regional Water Supply. A recirculation cooling system employing mechanically induced draft, evaporative cooling towers would be used. Water would be added to the cooling system to compensate for evaporative losses and blowdown. Blowdown is water bled from the cooling system to limit the build-up of salts.

The proposed Wanapa Energy Center would deliver electric power to the regional power grid at BPA's McNary Substation, using a new high voltage transmission line crossing property owned by the Port of Umatilla.
