03/21/2001 18:07 b ERD > 12f194683163 N0.178 906 III. Facility Overview Wellhead Power,LLC will operate a 49 MW generating unit,nominal,near Pacific as &Electric's Tesla substation site. The acreage for the proposed generating ficility G used for farming of annual crops. The placement of the facility has been chosen to minimize negative impacts to the landowner's operations and for convenient interconnection with PG&E's natural gas and electric transmission lines, which will both be within approximately 250 feet of the project site. The generating unit, associated equipment and buildings, and open space on the site will encompass approximately 1-5 acres and areas requiring protection and security will be enclosed with chain-link security fencing. It is expected that the generating unit will primarily operate during the period of June 1 through October 31 between the hours of 10:00 a.m-to 9:00 p.m, on weekdays- However,depending on the power supply situation in California,the generating unit could operate additional hours depending primarily on air permit 1mritations. The project is expected to be in service for an initial three-year terra, and depending upon contract and state peaking requirements up to eight years. The generating equipment win consist of gas turbine generators; modular control cabinets; associated ancillary equipment necessary to support operations of the gas turbine such as lube-oil skids,water pumps,water tanks, emissions control rnonitoM and a substation to increase the voltage from the generation voltage of 13.8 kV to the voltage of the adjacent transmission he of 115M It is expected the primary generators will be 49 mw Pratt&Whitney Twin-Pac gas turbine generator with associated equipment, or another equivalent natural gas fired turbine. The equipment selection when finalized will comply with all necessary permitting requirements. Environmental Considerations-, Water Resotoces and Waste Water Disposal Water will likely be used for one or two purposes, emission controland/or inlet-air cooling. Actual water requnenients will be driven by equipment selection,but usage is --- expected to be between 5 000 and 30,000 gallons lei' 1,0-houroperational day.ote at some equipment requires the use of water to reduce emissions, and the high volume water-use case would be due primarily to if such emissions controls are used. With an expected 100 to 125 days of operations per year,water usage would be between 500,000 and 3,000,000 gallons annually,or less than%acre-foot. WaUbead will either permit and develop a private well,or acquire water from the site-owner's well to serve this water requirement. Should the need for wastewater disposal be present(none is currently anticipated),necessary permits would be obtained before any discharge takes place.
