In a partial draft assessment, California Energy Commission staff found that Riverside Public Utilities' proposed 96 MW project would not result in significant environmental impacts if recommended conditions were incorporated into the project. The proposed plant is being reviewed under the commission's small power plant exemption, which was created for projects under 100 MW that qualify for a negative declaration under the California Environmental Quality Act because of minimal environmental harm. The project would be located on a 12-acre site near the city's wastewater plant in a light-industrial and manufacturing zone. It would use wastewater for cooling and include a zero-liquid-discharge system, and it would hook into Sempra's high-voltage lines. Staff await a historical survey report, as well as Federal Aviation Agency and Riverside County Airport Land Use Commission determinations, because the plant would be half a mile from an airport. The final staff study is expected to be released July 28.
