\_ ATTACHMENT L <br /> CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> COMPLAINT NO. ACL-003 <br /> ADMINISTRATIVE CIVIL LIABILITY COMPLAINT <br /> 1N THE MATTER OF <br /> CITY OF STOCKTON, <br /> REGIONAL WASTEWATER CONTROL FACILITY <br /> SAN JOAQUIN COUNTY <br /> This Complaint is issued to the City of Stockton (hereafter City) , based on the <br /> alleged violations of effluent limitations of Waste Discharge Requirements Order <br /> No. 80-116, and of provisions of Water Code Section 13350, which authorize the <br /> imposition of administrative liability. <br /> The Executive Officer finds, with respect to the City's acts or failures to act, <br /> the following: <br /> 1 . On eight occasions, from 3 June through 17 June, the City discharged <br /> effluent with total coliform counts greater than the effluent limita- <br /> tion of 500 MPN/100 ml . <br /> 2. On 17, 18, 19, and 20 June 1985, the Citv discharged a total of <br /> approximately 110 million gallons of effluent with pH values from 3.1 <br /> to 5.9. in violation of the effluent limitation of a minimum of 6.0. <br /> 3. On 19 and 20 June 1985 the City discharged a total of approximately 25 <br /> million gallons of effluent, with residual chlorine concentrations of <br /> uo to 10.5 ppm, in violation of the effluent limitation of 0.02 ppm. <br /> 4. The discharge of chlorine and low pH waste caused the death of <br /> approximately 5,000 fish in the San Joaquin River, according to the <br /> Department of Fish and Game (DFG) . <br /> 5. Violations described in Items 3, 4 and 5 above could have been <br /> prevented by ceasing discharge to the San Joaquin River. The City had <br /> ample storage capacity in on-site ponds available at the time. <br /> 6. The City did not have sufficient capacity to remove excess chlorine <br /> from plant effluent prior to its discharge on 19 and 20 June. <br /> Adequate dechlorination facilities would have prevented residual <br /> chlorine violations and may have prevented the fish kill . <br /> 7. The City created the conditions of high residual chlorine and low pH <br /> in its effluent by increasing the chlorine feed to the effluent in an <br /> attempt to achieve proper disinfection. The City knew that it was <br /> violating the chlorine effluent limitation within two hours, but <br /> allowed the discharge to continue for 24 hours. <br /> 8. On 19 and 20 June the City's effluent made up about 2/3 of the entire <br /> river flow. <br />
