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.
