Air quality data requests will follow at a later date. The staff workshop will focus on the applicant's data responses and possible resolution of identified issues.

Staff's data requests and the Issues Identification Report are available on the Energy Commission's website at The applicant's responses will be posted on the Commission's website as soon as possible after receipt. Following the workshop, staff will consider the comments it receives and initiate preparation of the Preliminary Staff Assessment (PSA) containing staff's preliminary analysis of the WPGS AFC and the potential impacts, including recommendations for mitigation and proposed conditions of certification.


On June 30, 2008, Mirant Willow Pass LLC (applicant) submitted an AFC to the California Energy Commission proposing to develop a nominal 550 megawatt (MW) combined cycle natural gas-fired power plant in the City of Pittsburg, Contra Costa County, California. The WPGS would consist of two, natural gas-fired Siemens Flex Plant 10 generating units which utilize dry cooling technology. The generating units, which would produce a total of 550 MW, would be connected to an adjacent PG&E switchyard within the existing Pittsburg Power Plant owned by Mirant.
