Between 2000 and 2003, ACS was responsible for four different Aquifer Protection Permit (APP) submittals in support of the design and construction of additional generating capacity at the APS/Pinnacle West Energy West Phoenix Power Plant in Phoenix, Arizona. Projects included the submittal of a Clean Closure Application for an abandoned borrow pit and spray pond at Units 1, 2, and 3; complete APP applications for Combined Cycle Units 4 and 5; and an APP Significant Amendment application for Combined Cycle Unit 5. Permitted facilities included brine concentrator ponds, a brine solids drying area, surge ponds, and ancillary equipment. ACS’ responsibilities included: research and writing of all of the sections of the applications/submittals except the hydrology sections which were compiled from previous reports; acting as a liaison with the project engineering contractor and review and compilation of the engineering information required for the Best Available Demonstrated Control Technology (BADCT) sections of the applications; compilation and writing of the technical (substantive) review responses to ADEQ; and interactions with the Arizona Department of Environmental Quality (ADEQ) on behalf of the client.
