Staff Assessment on Mariposa Energy Project Released
SACRAMENTO - The California Energy Commission staff released its analysis of the proposed Mariposa Energy Project today.
In its assessment, staff concluded that with the implementation of staff's recommended mitigation measures described in the conditions of certification, the proposed 200-megawatt plant would comply with all laws, ordinances, regulations, and standards (LORS), except for determinations in the areas of biological resources and transmission system engineering.
Staff plans to hold a workshop later this month to discuss the staff assessment. A supplemental staff assessment will be issued in December that will include updated analysis on biological resources and transmission system engineering.
The staff assessment provides the detailed environmental impact assessment required by the California Environmental Quality Act. It represents the Energy Commission staff's thorough and independent review of the project's potential impacts on the environment, public health, and safety.
The staff assessment is not a decision or proposed decision on the planned facility. It will serve as staff's testimony at the evidentiary hearing on the project to be scheduled by the Commission's hearing office and the committee of two commissioners reviewing the case.
The planned Mariposa Energy Project is a natural gas-fired, simple-cycle peaking facility with a generating capacity of 200 megawatts. The project, which is being proposed by Mariposa Energy, LLC, would be located in Alameda County about seven miles northwest of Tracy, seven miles east of Livermore, six miles south of Byron, and about 2.5 miles west of Mountain House.
The proposed project site is in an unincorporated area designated for agricultural use. The project is consistent with all county land use requirements. The facility would be located southeast of the intersection of Bruns and Kelso roads on a 10-acre portion of a 158-acre parcel south of the Pacific Gas & Electric Company's Bethany Compressor Station and Kelso Substation.
If approved, construction would begin in mid-2011, with commercial operation starting July 2012.
