Title

Addendum to Certified Environmental Impact Report Newell Creek Dam Inlet/Outlet Replacement Project

Description

The proposed Project modifications consist of a change to the maximum discharge rate of the outlet structure with a control to be installed on the new outlet discharge sleeve valve to provide a revised maximum emergency release rate of 203 cubic feet per second (cfs). This represents an increase of approximately 39 cfs above the maximum emergency release rate of 164 cfs that was evaluated in the EIR. The change is necessary to allow the valve to initially facilitate releases greater than the required emergency release in order for the facility to continue to meet drawdown requirements even with some anticipated diminished capacity as the facility ages.
