WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0148 -2-
<br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY
<br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY
<br /> SAN JOAQUIN COUNTY
<br /> BACKGROUND
<br /> 6. Musco Family Olive Company processes approximately one-half the total table olive crop in the
<br /> State. In 1999,the Discharger acquired an olive packing facility in Visalia, closed that facility,
<br /> and transferred the production to Tracy, without first making improvements to its existing
<br /> wastewater treatment or disposal system. That consolidation has lead to an increase in wastewater
<br /> flow rates and numerous violations of WDRs Order No. 97-037. The Regional Board responded
<br /> to the violations with various enforcement actions that are described below.
<br /> 7. The facility processes and cans olives on a year-round basis and generates wastewater with
<br /> extremely high concentrations of dissolved solids, sodium, and chloride. Processing consists of
<br /> receiving olives, storage in acetic acid solutions, curing in sodium hydroxide (lye), pitting, and
<br /> canning in a brine solution.
<br /> 8. Fresh olives are received at the facility during the harvest period of September through early
<br /> November each year. During,the harvest period, fresh olive processing and canning occurs.
<br /> Stored olives are processed the remainder of the year.
<br /> 9. The facility has approximately 37,000 tons of storage capacity and an additional 10,000 tons can
<br /> be processed fresh for a total storage capacity of approximately 47,000 tons. The facility can
<br /> process approximately 1,000 tons per week for a total processing capacity of 52,000 tons per year.
<br /> 10. The facility is equipped with 734 storage tanks ranging in size from 3,600-gallons to 8,800-gallons
<br /> and 98 processing tanks that are 2,500-gallons each. Additional olives are stored at the
<br /> Discharger's Visalia and Orland facilities and are trucked to Tracy for processing.
<br /> 11. The quality of the individual wastewater streams was described in the RWD. A summary is
<br /> presented below. The source of each of the streams is presented in the flow diagram found in
<br /> Attachment B, which is attached hereto and made part of the Order by reference. All of the
<br /> wastewater streams described below are mixed in the 1-million gallon settling pond prior to
<br /> discharge to the land application areas. Other waste streams are discharged to the Title 27 ponds.
