The State Water Resources Control Board (State Water Board) is a Responsible Agency for the Project. The State Water Board’s Clean Water State Revolving Fund (SRF) Program is financing the Project. The proposed Project serves to replace aging standby generators and auxiliary equipment, and to adequately supply reliable standby power to existing plant electrical loads for peak demand periods and to facilitate future standby power improvements. The Project will (1) Replace six existing standby engine generators in a new Standby Power Building containing three new minimum-rated 2.5 megawatt (MW) standby engine generators, with space for one additional future minimum-rated 2.5 MW generator, and associated electrical and control equipment; (2) Construct transformers, to be located on the eastern side of the Standby Power Building; (3) Construct one new above-ground 20,000-gallon fuel storage tank, with space for a future tank, to be located along the western side of the new Standby Power Building; (4) Add new duct banks as follows: (a) Approximately 100 feet of 480-volt duct bank from the Standby Power Building to Switchgear SWGR-SE (to be constructed under a separate project), and (b) approximately 200 feet of 480-volt duct bank from Substation No. 2 to the Odor Control Building; and (5) Demolish selected structures and equipment. All construction activities associated with the project will occur within the existing Alvarado Wastewater Treatment Plant (WWTP) site.
