March 8, 2005 NOA PROJECT NUMBER E04070B Sludge and other solids shall.be removed from wastewater treatment equipment, sumps, ponds etc. as needed to ensure optimal plant operation and adequate hydraulic capacity. Drying operations shall take place such that leachate does not impact the quality of ground or surface F1 water. 8.8 Groundwater Limitations F1 The discharge, in combination with other sources, shall not cause underlying groundwater to contain waste constituents in concentrations greater than natural background water quality. 8.9 Provisions FState Board Resolution No 68-16 requires that the discharge be required to meet waste discharge requirementswhich will result in Best Practices Terminal Control (BPTC) of the discharge to assure that pollution or nuisance will not occur and the highest water quality consistent with the maximum benefit to the people of the United States be maintained. 8.10 Treatment Asparagus will be spray washed on a conveyor with uncooled non-chlorinated water. The clean asparagus will then be packed into boxes and sprayed for five to seven minutes with chilled chlorinated water in two hydro-cooler units. The chlorine concentration will be 50 to 60 mg/l and this water will be recycled during processing activities. Starting in 2005, hydrocooler water will be treated by sodium thiosulfate to neutralize free chlorine then be discharged into the wastewater pond twice weekly as recommended by the BPTC. Cherries will be rinsed with non cooled water followed by the chilled chlorinated water. The chlorine concentration will be 50 to 60 mg/1 and this water will be recycled during processing activities. Starting in 2005, the hydrocooler water will be treated by sodium thiosulfate to neutralize free chlorine then be discharged into the wastewater pond twice weekly as recommended by the BPTC. ILI Stormwater is collected from paved areas and buildings and is piped to the storage pond. Because industrial wastewater is mixed with stormwater in the pond, all the water collected in Hi the pond will be handled and disposed of as industrial wastewater. A balance that demonstrates adequate storage and disposal capacity for the wastewater and stormwater that will be generated on site is presented in MPF's RWD. (See appendix) MPF's treatment of process wastewater consists of screening prior to discharge into the wastewater pond. Wastewater in the pond will be further treated through biological activity, settling and volatilization of organic compounds. If the pond generates odors or if the dissolved oxygen (DO) level is less than 1.0 mg/1 then an aerator will be added to the pond. Wastewater effluent data collected during 2004, showed DO levels ranging from 3.8 mg/1 to 14.0 mg/l. These levels indicate no aeration will be needed immediately. Fi 7
