WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0148 -3- MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY SAN JOAQUIN COUNTY 12. Attachment B presents a process flow diagram and describes the disposal for each waste stream. Review of the data presented in the table above and the disposal location for each waste stream reveals that high strength wastewater is discharged to the land application system. 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 central collection area from which it is either directed to the Title 27 ponds or is pumped to a 1-million gallon settling pond. Despite requests for the information, the Discharger has not 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 is directly applied to the land application areas. Once the new 84-million gallon storage pond is completed, all wastewater will be pumped from the 1-million gallon settling pond to the 84-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 February 2002 (when a flow meter was installed) through June 2002 shows that daily flow discharged to land ranges from 71,334 to 1,457,810 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 30 June 2002, the average concentrations of analytes in the wastewater discharged to the land application system were: Constituent Units Wastewater Biochemical Oxygen Demand mg/l 3,040 Electrical Conductivity µmhos/cm 4,210 I
