INFORMATION SHEET <br /> ORDER NO. <br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY <br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY <br /> SAN JOAQUIN COUNTY <br /> Musco Family Olive Company and the Studley Company (Discharger) operate an olive cannery near <br /> Tracy, San Joaquin County. The Tracy facility is equipped with 734 storage tanks ranging in size from <br /> 3,600-gallons to 8,800-gallons and 98 processing tanks that are 2,500-gallons each. Additional olives are <br /> stored at the Discharger's Visalia and Orland facilities and are trucked to Tracy for processing. The <br /> facility has approximately 37,000 tons of storage capacity and an additional 10,000 tons can be processed <br /> fresh for a total storage capacity of approximately 47,000 tons. The facility can process approximately <br /> 1,000 tons per week for a total processing capacity of 52,000 tons per year. <br /> Olives are stored in an acetic acid solution prior to processing. Processing the olives requires immersing <br /> the raw olives in lye solutions to cure the olive, then drawing the lye out of the olives with successive <br /> baths of fresh water. The olives are pitted prior to canning in a brine (sodium chloride) solution. <br /> Processing occurs year round, with fresh olives processed from September through early November and <br /> stored olives processed the remainder of the year. <br /> Process wastewater generated at the facility is regulated by two separate WDRs. Order No. 96-075 <br /> regulates the two Title 27 surface impoundments that are used to store concentrated brines; Order No. <br /> 97-037 regulates the less concentrated wastewater that is applied to land. This WDR update only applies <br /> to the less concentrated wastewater. <br /> Local land use consists of industrial, residential, and agricultural operations. The site is located on an <br /> alluvial fan that generally slopes to the northeast. Topography vanes from steep to nearly level. Surface <br /> water drainage from the facility is to the Sacramento San Joaquin Delta. <br /> WASTEWATER SYSTEM <br /> A wastewater system is used to collect and apply the industrial wastewater to land. Wastewater is <br /> collected throughout the facility by floor drains and is piped to a central collection area. Despite requests <br /> for information, the Discharger has not fully described how it determines whether to discharge to the land <br /> application system or the Title 27 ponds. From the 1-million gallon pond, the wastewater may either be <br /> applied directly to the land application areas or it may be stored in a new 84-million gallon storage pond <br /> prior to land application. The facility consists of 280 acres, of which approximately 200 acres are <br /> available as wastewater land application areas. <br /> Wastewater is characterized by high concentrations of organic matter, total dissolved solids (TDS), <br /> sodium, and chloride. Waste lye solutions, carbon dioxide neutralization water, pit floatation brine, ion <br /> exchange regeneration brine, and boiler blow down are discharged to the Title 27 ponds. Lye rinse water, <br /> cooling water, wash waters (including weak lye solutions), acetic acid storage solutions,pitting machine <br /> wastewater, clean-in-place solutions, and cannery floor wastewater(despite high TDS concentration), are <br /> sent to the land application system. <br /> The treatment for process wastewater discharged to land consists of carbon dioxide neutralization of lye <br /> rinse solutions, screening solids using a mechanical screen and rake, and discharge to the 1-million gallon <br /> settling pond. , <br />
