GENERAL DESCRIPTION OF PROJECT
On March 29, 2001, East Altamont Energy Center, LLC, a wholly owned subsidiary of Calpine Corporation, filed an Application for Certification (AFC) for a nominal 1,100 MW power plant called the East Altamont Energy Center (EAEC). The proposal is for a natural-gas-fired, combined-cycle generating facility with a 230-kilovolt (kV) switchyard and approximately 0.5 miles of new 230-kV transmission lines.
The applicant's proposed site lies within a 174-acre parcel of land under the applicant's control, located in unincorporated Alameda County, approximately one-mile west of the San Joaquin County line and 1.0 mile southeast of the Contra Costa County line. The site is bordered by Byron Bethany Road to the north, Kelso Road to the south, and Mountain House Road to the west. If built, the plant would occupy up to 55 acres near the center of the property, with the remainder available for lease as agricultural land.
The project is estimated to have a capital cost of between $400 and $500 million. If the project is approved by the Energy Commission, the applicant plans to begin construction in June 2002 and complete construction in June 2004. The project would provide for a peak of approximately 400 construction jobs over a two-year period and up to 40 skilled positions throughout the life of the project.
Energy Commission Facility Certification Process
The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
