On April 21, 2003, the Modesto Irrigation District (MID) filed an application for Small Power Plant Exemption (SPPE) seeking an exemption from the California Energy Commission's licensing requirements.

MID proposes to construct and operate a 95-megawatt (MW) generation plant called the Modesto Irrigation District Electric Generation Station (MEGS). The project is proposed to be located on a 12.25-acre site at South Stockton Avenue and Doak Boulevard in Ripon, California, in San Joaquin County and will occupy approximately six acres near the northern side of the project site. If an exemption is granted, the applicant will need to secure the appropriate licenses and permits for the project from various local, state and federal agencies.

The 95-megawatt natural gas-fired simple cycle plant will consist of two General Electric LM 6000 SPRINT combustion turbines. Part of the proposed project includes the construction of approximately 1/4-mile of new 69-kilovolt sub-transmission line and fiber optic cable, approximately 1/4-mile of new eight-inch natural gas supply line, and water supply and wastewater tap lines into the existing City of Ripon lines located on South Stockton Avenue.

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.
