Calpine Construction Finance Company (Calpine), the project owner, filed a petition, dated January 10, 2007, with the California Energy Commission requesting to delete conditions of certification AQ-32 (5) and AQ-32 (6).

The 540 megawatt project was certified by the Energy Commission on April 14, 1999, and began commercial operation on July 2, 2001. The facility is located in Sutter County, near Yuba City, California.


Calpine is requesting deletion of conditions of certification AQ-32 (5) and (6). Condition AQ-32 (5) limits the number of startup hours per combustion turbine generator (CTG) to 400 hours per year and 102 hours per quarter. Condition AQ-32 (6) limits the maximum duration of shutdowns to 300 hours-per-year and 76 hours per calendar quarter. Calpine believes that these durational limits may force the facility to shutdown during periods of critical power demand based on recent experience when the quarterly duration limit for startups was approached.

Calpine states that conditions AQ-32 (5) and (6) are unnecessary because startup emissions are sufficiently limited by conditions AQ-32 (2) and (4), which limit the amount of time that the CTGs can remain in shutdown and startup modes per incident; AQ-32 (11), which limits the emissions during startup and shutdown modes per incident; and AQ-32 (12), (13), and (14), which limit daily, quarterly, and annual emissions from the facility. No changes to any emission limits have been requested.


The purpose of the Energy Commission's review process is to assess the impacts of this proposal on environmental quality, and public health and safety. The review process includes an evaluation of the consistency of the proposed changes with the Energy Commission's Decision and if the project, as changed, will remain in compliance with applicable laws, ordinances, regulations, and standards (Title 20, Calif. Code of Regulations, section 1769). Energy Commission staff is currently analyzing the request and will publish an analysis in the next several weeks. A public hearing for the purpose of approving or denying the amendment proposal will subsequently be held at a regularly scheduled Energy Commission business meeting.

This Notice of Receipt is being mailed to interested parties and property owners adjacent to the project site who may want to participate in the amendment process.

The petition is available on the Energy Commission's website at http://www.energy.ca.gov/sitingcases/sutterpower/compliance/index.html. The staff analysis (when published), and the Energy Commission Order (if approved), will also be posted on the website. If you would like to receive a hard copy of the petition, staff's analysis, and/or the Energy Commission Order if the changes are approved, please complete the enclosed Information Request Form and return it to the address shown.
