e. CEASE AND DESIST ORDER NO. -2- AND CWC SECTION 13308 ORDER MUSCO OLIVE PRODUCTS AND THE STUDLEY COMPANY SAN JOAQUIN COUNTY 9. A review of the self-monitoring reports from January 2000 through September 2001 shows that daily flow discharged to land ranges from 8,610 to 1,616,927 gpd, and that the permit limit of 500,000 gpd was exceeded 47% of the time. During this same time, the total dissolved solids (TDS) concentrations in the wastewater ranged from approximately 2,500 to 5,600 mg/1. Dissolved Inorganic Solids (DIS)concentrations ranged from 812 to 3,712 mg/l, with an average concentration of 2,421 mg/l. These values exceed both the average and maximum DIS loading limits contained in the WDRs. Sodium and chloride are also present at elevated concentrations in the wastewater. Sodium has been reported at average concentrations of approximately 864 mg/l; chloride has been reported at average concentrations of approximately 557 mg/l. 10. The Discharger's facility is on approximately 320 acres, of which approximately 200 acres are available for land application of process wastewater. Wastewater is currently spray irrigated to land containing mainly volunteer weeds and grass. During the year 2001, the Discharger planted 10 acres with perennial grass, 15 acres of Sudan grass, and unknown acreages of oats and sorghum. Only the sudan grass appears to have grown well. Because too much wastewater is applied to the land application areas, a significant amount of tailwater is generated. In correspondence dated 27 December 2001 the Discharger reported 25 acres of winter wheat/rye has been planted. 11. The Discharger has stated that approximately 350 employees work on-site. Based on San Joaquin County Environmental Health Department (SJCEHD)records dated 25 October 2001, the facility is served by a septic tank that was sized for 164 employees. The records indicate the septic tank effluent discharges to eight, 95-feet long leach lines that are equipped with 25-feet deep seepage pits at the ends. The Discharger recently began applying industrial wastewater to the land over the leach lines. This will likely reduce the infiltration capacity of the soil and may impact the underlying groundwater quality. VIOLATIONS OF THE WASTE DISCHARGE REQUIREMENTS 12. A 2 November 2001 review of the facility and land application areas, as well as a review of the case file, revealed numerous violations of the WDRs. On 30 November 2001 a Notice of Violation was transmitted to the Discharger. The violations of the WDRs are summarized below: a. WDRs Finding No. 5 limits the wastewater flow rate at 500,000 gallons per day. Between January 2000 and September 2001, the Discharger has exceeded the flow rate 47%of the time. Additionally, the Discharger has failed to accurately monitor the flow rate using a meter. b. WDRs Findings No. 5, 7, and 17 limit the wastewater application to cropped areas. The Discharger has failed to plant crops on most of the land application areas. The small areas that have been cropped show severe plant tissue damage. c. WDRs Prohibition No. A.1 prohibits discharge of wastewater to surface water drainage courses. The Discharger has routinely used surface water drainage courses to convey wastewater. Two berms have been installed across the surface drainage to control tailwater running off the slopes from escaping the site. In addition, the Discharger has installed an overfill pipe from the one million gallon storage pond to the surface water drainage. d. WDRs Prohibition A.3 prohibits discharge of designated waste to the land application system. The Discharger is mixing designated waste into the land application wastewater CAMy D�tsET%fbrc=kcn1\M=o 01ivcWusco C&Mdoc
