SRP operates the Santan Generating Station (SGS), a steam power electric generating plant in Gilbert, Ariz. On Aug. 17, 2016, ADEQ received a request from the permittee to modify the AZPDES permit, which became effective on Feb. 20, 2014. The modification request includes a new outfall (outfall 021) that discharges to the SRP Canal System. The SRP SGS is considered a major industrial facility that discharges cooling tower blowdown with other low-volume waste sources.
