Document Description
The proposed project would replace existing, aging facilities at the WPCP, including replacements of the headworks facility, primary treatment facilities, switchgear building, standby generator, and heat recovery system at the power generation facility. Access roadways and fencing would also be altered or replaced, a stormwater channel along the southeast boundary of the WPCP site would be filled, and dewatering would be relocated within the WPCP site. These alterations will occur within the main plant as well as in surrounding areas of the WPCP. For the oxidation ponds, the proposed Project may include, but is not limited to, construction of a new road by expanding the existing levees between Pond 1 and 2 on the west side of Note: Review Per Lead & Addendum Moffett Channel, replacement of existing pipelines, and extension of the primary effluent pipeline to new equalization basin. Following adoption of the IS/MND, the city proceeded with design of the primary treatment facility, including making adjustments to the design to better meet city objectives. Project modifications have been made to the facilities that would be constructed within the plant fenceline.
