ORDER NO.R5-2002-0148 - 20 - <br /> INFORMATION SHEET <br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY <br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY <br /> SAN JOAQUIN COUNTY <br /> dissolved oxygen content in the upper 12 inches of any liquid impoundment to be maintained at no less <br /> than 1.0 mg/L. <br /> Technical Reports Required by the Provisions <br /> The Discharger is required to submit a workplan for characterization of groundwater quality and <br /> percolate quality at the land treatment units (land application areas). The groundwater well workplan <br /> will allow further evaluation of groundwater conditions upgradient and downgradient of the newly <br /> constructed 84-million gallon storage pond and in the land application areas. In addition, installation of <br /> lysimeters are required to determine the quality of the percolate at the bottom of the land treatment units <br /> (at a depth of five feet). Lysimeters shall be installed in both the land application areas and in an area <br /> where no land application of wastewater has occurred. <br /> The Discharger is required to submit a BPTC Salinity Source Reduction Plan because the available data <br /> on groundwater quality, wastewater quality, and crop uptake indicates the wastewater application could <br /> impact groundwater quality. This Workplan must contain plans to reduce the concentration of TDS <br /> constituents, organic constituents, and hydraulic loading. <br /> The Discharger is required to submit an assimilative capacity report for the LTUs (land application <br /> areas). The report shall evaluate the LTU's capacity to treat the wastewater constituents being applied. <br /> This requirement is needed to determine the adequacy of the land treatment. The wastewater contains <br /> high concentrations of constituents, such as sodium and chloride, that are not biologically treated and an <br /> evaluation of the effectiveness of land treatment to protect groundwater quality is needed. <br /> The Discharger shall submit a technical report describing specific numerical water quality criteria prior <br /> to being allowed to bypass the 84-million gallon storage pond. This item is discussed above in <br /> "Discharge Prohibition A.5." <br /> The Discharger is required to submit an Operation and Maintenance Plan to ensure that all persons <br /> responsible for irrigation and monitoring are aware of their responsibilities and are appropriately trained. <br /> This is required because a single reference document that includes the WDRs, instructions for operation, <br /> odor minimization procedures, and other information must be available to operators of the system in a <br /> timely manner. Because the Discharger will be storing odor control chemicals on site that are expected <br /> to be used infrequently, it is important for operators to be able to refer to the O&M Plan for use <br /> instructions. <br /> The Discharger is required to submit a Groundwater Well and Lysimeter Installation Report to <br /> document the installation of the wells and lysimeters. <br /> The Discharger is required to submit a Background Groundwater Quality and Percolate Quality Report. <br /> This report is required to allow determination of the effect of wastewater application on the groundwater <br /> quality. If a groundwater quality degradation is observed, upon request of the Executive Officer the <br /> Discharger will be required to submit a Groundwater Mitigation Plan. <br /> AMENDED <br /> TRO: 9/6/02 <br />
