Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Reasons for Exemption
The Class 1 categorical exemption applies because the Project involves minor operational alterations to an existing facility with no construction or expansion of use. The Project involves flow prescriptions and ramping rates from Dam 7 into the San Joaquin River for the benefit of aquatic species and recreation. The Class 6 exemption applies to the long-term monitoring, which will not result in a serious or major disturbance to an environmental resource. There is no reasonable possibility that the Project will have a significant effect due to unusual circumstances.
