Box San Francisco, CA Fax : August 16, 2017 (Pacific Gas and Electric Company ID U 39 M) Public Utilities Commission of the State of California Subject: Add Five Hydroelectric Watershed Areas to Hazardous Substance Mechanism Purpose Pacific Gas and Electric Company (PG&E) hereby requests California Public Utilities Commission (Commission or CPUC) approval to include additional sites within five hydroelectric watershed areas in the Hazardous Substance Cost Recovery Account as referenced within Gas Preliminary Statement Part AN and Electric Preliminary Statement Part S, Hazardous Substance, in compliance with Decision (D.) PG&E has identified various hydroelectric facilities within five watershed areas which historical operations included the use, storage, and/or repair of utility equipment that contained mercury and may have contained other hazardous substances. PG&E plans to conduct environmental assessments at these sites to identify and remediate hazardous substance releases which may have occurred in order to protect worker safety, public health, and the environment. A description of all five watershed areas and associated hydroelectric facilities is set forth in Attachment I to this filing. The watershed areas and locations are as follows: Watershed Area Location Shasta Pit #1 Powerhouse, Shasta County Pit #4 Powerhouse, Shasta County Pit #6 Powerhouse, Shasta County Pit #7 Dam, Shasta County James Black Powerhouse, Shasta County Cow Creek Powerhouse, Shasta County Volta #1 Powerhouse, Shasta County Inskip Powerhouse, Tehama County South Powerhouse, Tehama County
