WASTE DISCHARGE REQUIREMENTS ORDER NO. • -3 MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY WASTEWATER TREATMENT FACILITY SAN JOAQUIN COUNTY 13. A wastewater system is used to collect and apply the industrial wastewater to land. Wastewater is collected throughout the facility by floor drains and is piped to a concrete-lined central collection sump. Depending on the strength of the wastewater, it is either directed to the Title 27 ponds or is pumped to a 1-million gallon settling pond. The Discharger can only pump to one location at a time; therefore, the destination of wastewater is determined by the activity generating the wastewater. Despite requests for the information the Discharger has not provided the logic controls or fully described how it determines whether to discharge the wastewater to the land application system or the Title 27 ponds. 14. From the 1-million gallon pond, the wastewater may either be applied directly to the land application areas or it may be stored in a new 114-million gallon storage pond prior to land application. The facility consists of 280 acres, of which approximately 200 acres are available as wastewater land application areas. 15. WDRs Order No. 97-037 states that the wastewater flow to the land application areas will be approximately 500,000 gallons per day (gpd). A review of the self-monitoring reports from January 2002 through May 2002 shows that daily flow discharged to land ranges from 76,296 to 3,729,753 gpd. 16. The treatment for process wastewater discharged to the land application areas consists of carbon dioxide neutralization of lye rinse solutions, screening solids using a mechanical screen and rake, and discharge to the 1-million gallon settling pond. 17. Lye is reclaimed in above ground stainless steel tanks located near the 1-million gallon settling pond. Lye is reclaimed through the addition of sodium hydroxide to the tank. Lye that is too contaminated for further use is discharged to the Title 27 ponds. 18. The facility is equipped with a clean-in-place system. The clean-in-place system is used to clean piping associated with the accumulation tanks in the cannery. Caustic cleaner is used in the system, and the resulting wastewater is discharged to the land application area. 19. Boiler feed water is treated with an ion exchange column. The ion exchange column is regenerated in place; the RWD reported regeneration brine is discharged to the Title 27 ponds. 20. Wastewater that is discharged to the land application system is characterized by a high organic matter and dissolved solids content. In the time period from 1 January 2002 to 31 March 2002 (the time period from which the revised Monitoring and Reporting Program was in force and prior to preparation of the RWD), the average concentrations of analytes in the wastewater discharged to the land application system were: Constituent Units Wastewater Biochemical Oxygen Demand mg/1 1,928 Electrical Conductivity µmhos/cm 4,256 Total Dissolved Solids mg/1 4,675 Dissolved Inorganic Solids mg/1 2,638 V.'du_bpu RnISSVRO+IsiJl�..\Wp1.MAx
