Project Summary: The Sunrise Cogeneration and Power Company is proposing to construct and operate a 320 MW natural gas-fired cogeneration power plant. The Sunrise site is approximately 35 miles southwest of Bakersfield, 3 miles northwest of Fellows, and 2.5 miles south of Derby Acres. The power plant and related facilities, such as the electric transmission line, natural gas pipeline, and water lines, are under the California Energy Commission's (Energy Commission) siting authority.

Issue Summary: The proposed Sunrise Cogeneration and Power Project (SPCC) will use approximately 5.4 million gallons per day of treated produced water from the Texaco California, Inc. (TCI) oilfield operations as make-up water for the heat recovery steam generator (HRSG).

Treatment processes at the existing water treatment facility located within the oilfield include oil/water separation, filtration and water softening. Water softener regeneration brine from the water treatment facility is sent to the Valley Waste Buena Vista No. 2 (Valley Waste) facility for disposal. An intervenor in the siting case, California Unions for Reliable Energy (CURE), has expressed concern that ambient concentrations of benzene and mercury, and perhaps other constituents in the produced water, exceed California hazardous waste characteristics criteria, as set forth in Title 22, California Code of Regulations, Article 2, Section 66261.10 et seq.

In addition, wastewater streams from additional treatment and use of the softened produced water at the proposed cogeneration facility may also exceed hazardous waste characteristic criteria. Wastewater from the proposed cogeneration project will also be disposed of at the Valley Waste facility. Based upon information provided by CURE, staffs of the California Department of Toxic Substances Control (DTSC) and the Energy Commission agree that additional information is necessary to determine whether hazardous waste treatment permits are necessary and whether the appropriate disposal methodology has been selected.
