Proposed Decision Recommends License for Mariposa Energy Project


SACRAMENTO - A California Energy Commission siting committee is recommending the approval of the planned Mariposa Energy Project in northeastern Alameda County.

In its presiding member's proposed decision (PMPD) released today, the committee said the 200-megawatt facility, as mitigated, will have no significant impacts on the environment and complies with all applicable laws, ordinances, regulations, and standards.

The proposed decision was based solely on evidence developed in evidentiary hearings during the facility's certification proceeding.

The PMPD is not a final decision on the project. The siting committee released the document for 30 days of public comment. The committee will consider input before bringing the proposed decision to the full Energy Commission. The entire document can be found on the Energy Commission's website at: http://www.energy.ca.gov/sitingcases/mariposa/documents/index.html

The PMPD determined that the record, which contains a detailed environmental impact assessment required by the California Environmental Quality Act, was adequate. The record includes the Energy Commission staff's thorough and independent assessment of the project's potential impacts on the environment, public health, and safety.

The Mariposa Energy Project is a natural gas-fired, simple-cycle peaking facility. The project would be located 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. Mariposa Energy, LLC, which is owned by Diamond Generating Corporation, is the project applicant. Diamond Generating Corporation is a wholly-owned subsidiary of Mitsubishi Corporation.

The proposed project site is in an unincorporated area designated for agricultural use. 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 Pacific Gas & Electric Company's Bethany Compressor Station and Kelso Substation.
