i • STAFF REPORT -2- STOCKTON COGENERATION COMPANY SAN JOAQUIN COUNTY more than 5°F in North Littlejohns Creek, 100 feet downstream of the outfall. The Order also includes an interim limitation for temperature applied at French Camp Slough. The Discharger has shown the ability to comply with the interim limitations required in Receiving Water Limitations E.1 and E.8. However, the Discharger is unable to comply with the final limitations. Since the beneficial uses of North Littlejohns Creek are not specified in the Basin Plan, the Discharger has requested a site-specific basin plan amendment to determine the beneficial uses of North Littlejohns Creek. This request was based on Draft Orders addressing petitions challenging NPDES permits for the Cities of Vacaville and Turlock that are under consideration by the State Water Resources Control Board (State Board). This Resolution amends Order 5-01-119 to provide an extension of the compliance schedules one year for Receiving Water Limitations E.1 and E.8. The extension is needed to evaluate the applicability of the pending Orders by the State Board,with respect to the Stockton Cogeneration Facility. The new compliance date will be 1 November 2003. Chlorine Residual—The Discharger also requested an extension of the effluent chlorine residual limitation required in Effluent Limitation B.1,which becomes effective 1 November 2002. The Discharger has demonstrated the ability to meet the new limitation,but requested an extension due to uncertainty that arose from recent negative chronic toxicity test results. Since chlorine is acutely toxic to aquatic life, and the Discharger is capable of meeting the new chlorine residual limitation, Regional Board staff do not recommend extending the compliance schedule. Recommendation: Adopt the proposed resolution amending Order No. 5-01-119.
