Document Description
The Contra Costa Water District (CWWD) intends to adopt a Mitigated Negative Declaration for the proposed project. The project consists of the construction and operation of a new pump station and discharge outfall on Veale Tract to relocate agriculture drainage from its current discharge point into Rock Slough to a new location on Werner Cut/ Indian Slough. CCWD could also design and implement agricultural best management practices (BMPs) provided that BMPs were approved by Reclamation District 2065 and Veale Tract landowners, funding was made available, and if the BMPs cause no significant environmental impacts. The primary purpose of the proposed project is to reduce the adverse water quality effects of agricultural drainage from Veale Tract on the beneficial uses in Rock Slough, including CCWD's municipal water supply diversion from Rock Slough at its Contra Costa Canal Pumping Plant #1.
