Document Description
PG&E is proposing to temporarily lower the minimum instream flows below the Pit 3 dam and Pit 5 diversion dam to 75 cubic feet per second (cfs) in order to perform dive inspections of its Pit 3 dam and Pit 5 diversion dam facilities. Flows will be reduced from 280 cfs at the Pit 3 dam and 350 cfs at the Pit 5 diversion dam. Dive inspections are required as a result of flood events that occurred from February 3-21, 2017, in accordance with the Pit 3 Dam Safety Surveillance Monitoring Program and the Pit 5 standard operating procedures.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
15301, Class 1
Reasons for Exemption
The Class 1 exemption applies because the Project involves minor operational alterations to an existing facility with no construction or expansion of use. Temporary reduction of instream flows at the Pit 3 dam and Pit 5 diversion dam will not have a significant adverse effect on the environment. The lower instream flows are required so divers can safely enter the water to inspect the dams. There is no reasonable possibility that the Project will have a significant effect due to unusual circumstances.
