Pit 3 Dam PH-37A Weir Modification Project
Document Type
NOE - Notice of Exemption

Document Description
FERC has requested modifications to an existing weir to capture only leakage from the left dam abutment, rather than as is the current situation where leakage from both the hillside and the left abutment are captured and measured together. PG&E intends to make these modifications by constructing a new weir on top of the training wall on the left abutment downstream of the dam, and modify the existing low-level weir to capture and accurately measure the hillside flows alone by adding a leakage containment wall to the existing containment wall.
