WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0148 -7- MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY SAN JOAQUIN COUNTY lbs/ac-day. These values exceed the BOD effluent limitations presented in Section C. The Discharger is required to take the necessary steps to reduce its BOD to meet the conditions of this Order. OTHER WASTE STREAMS 33. Solid waste generated at the site includes olive pits, stem waste, waste olives, screened solids, steel cans, and cardboard, plastic, paper, and miscellaneous trash. Olive pits and stems are sold as biomass and burned at cogeneration plants or pulverized and incorporated into compost. Some olive pits are spread onto the dirt roads at the site. Waste olives are transported offsite for animal feed or offsite land disposal. Screened solids are transported offsite for land disposal at a landfill. Steel cans, plastic,paper, and miscellaneous trash are hauled by a disposal company to a landfill. 34. The Discharger submitted a Draft Stormwater Pollution Prevention Plan (S WPPP) on 5 June 2002 to address industrial activities at the facility that are exposed to storm water. Stormwater that falls on areas of industrial activity is collected and discharged to the 1-million gallon settling pond. Stormwater that falls on land application areas is collected and pumped to either the 1-million gallon settling pond or the 84-million gallon storage pond. Stormwater that falls on areas of the facility that are not likely to be contaminated is proposed for bypass around the 84-million gallon storage pond and discharge to the natural drainage feature. In two areas, stormwater that falls on the facility is not collected, and the revised SWPPP must address this issue. 35. 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, and as described in the 29 May 2002 Revised Report, Domestic Wastewater System, the facility is served by a septic tank system that was sized for 164 employees. The Discharger has reevaluated the domestic wastewater system as required by Time Schedule Order No. R5-2002-0014 and determined an expansion is required. 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. In accordance with the SJCEHD requirements, the Discharger will expand the existing septic system by adding four additional 95-feet long leach lines that will each terminate with a 25-feet deep seepage pit. The Discharger has stated that it will no longer apply wastewater over the leach lines or seepage pits. Domestic wastewater is not commingled with the process water that is land applied. ENFORCEMENT HISTORY 36. Due to numerous violations of its WDRs, on 17 November 2000 the Executive Officer issued Cleanup and Abatement (C&A) Order No. 5-00-717 to the Discharger. The C&A Order required the Discharger to prepare technical reports and construct wastewater treatment system improvements to comply with WDRs No. 97-037 by 1 November 2001. 37. Because the Discharger did not comply with the C&A Order, the Regional Board adopted California Water Code (CWC) Section 13308 Time Schedule Order(TSO)No. R5-2002-0014 on 25 January 2002. The TSO provided interim higher flow and DIS limits, required control of nuisance odors, installation of groundwater monitoring wells, an evaluation of the domestic
