Marsh Landing Generating Stattion Corrective Measures Study

NOD - Notice of Determination

Document Description
The proposed project consists of implementation of a Department of Toxic Substances Control (DTSC) approved Corrective Measures Study (CMS) submitted by Pacific Gas and Electric Company (PG&E) in accordance with Division 20, Chapter 6.5 of the California Health and Safety Code. The CMS specifies the excavation of an estimated 250 to 300 cubic yards of soil contaminated with polynuclear aromatic hydrocarbons from specified locations and the transportation of this soil to a permitted off-site disposal facility. The soil will be excavated from an area less than an acre in size. The excavation is expected to have a maximum depth of six feet below ground surface and is estimated to take approximately three calendar weeks to complete. DTSC approval of the project is conditional upon a commitment by PG&E to investigate and remediate contaminated groundwater associated with past releases at the facility. This Notice of Determination does not apply to any future groundwater investigation or remediation activities. Activities proposed in the CMS are to occur prior to construction and operation of a 760-megawatt (MW) natural gas-fired power plant; the Marsh Landing Generating Station (MLGS). The MLGS will be constructed, owned, and operated by Mirant under a license granted by the California Energy Commission (CEC), which previously prepared and certified an environmental impact assessment (CEC Staff Assessment) as the Lead Agency for the MLGS, including proposed CMS activities, under the California Environmental Quality Act (CEQA),
