WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0148 -26- <br /> MUSCO FAMILY OLIVE COMPANY AND THE STUDLEY COMPANY <br /> WASTEWATER TREATMENT AND LAND DISPOSAL FACILITY <br /> SAN JOAQUINCOUNTY <br /> a. By 1 November 2002, the Discharger shall submit a report describing the following: <br /> i. The installation of sufficient aerators in both the 1-million gallon and the 84- <br /> million gallon ponds such that the requirements of Discharge Specification No. <br /> B.5 will be continuously met. The report shall clearly show the calculations used <br /> to determine the number and size of the aerators. <br /> ii. When a portable sprayer tank was purchased, and how and when the portable <br /> sprayer tank will be used to provide rapid odor suppression around the banks and <br /> water surface of the ponds. <br /> iii. The installation and location of sufficient flow meters to comply with the flow <br /> measurement requirements of Monitoring and Reporting Program No. <br /> R5-2002-0148. <br /> iv. The retrofitting of the irrigation system such that all sprayfields can be operated <br /> with short (i.e., 15 minute) irrigation durations. <br /> b. By I November 2002, the Discharger shall submit a workplan for additional <br /> characterization of(a) groundwater quality around the 84-million gallon storage pond <br /> consisting of a minimum of one well upgradient and two wells downgradient of the <br /> storage pond, (b)percolate quality under the LTUs, and(c) additional studies needed to <br /> investigate the groundwater hydrogeology of the facility that will include, at a <br /> minimum, investigation of the high TDS concentrations measured at Well MW-2, <br /> installation of additional wells to replace monitoring wells that have gone dry since <br /> installation, and further investigation of the occurrence and quality of groundwater <br /> beneath the land application areas. The goal of the investigation is to determine the <br /> background groundwater quality at the site and measure any impact to groundwater <br /> quality caused by wastewater storage ponds. Monitoring wells shall be constructed to <br /> yield representative samples from the aquifers identified in the July 2002 groundwater <br /> monitoring report and shall comply with applicable well standards. In addition, the <br /> workplan shall describe the installation of an adequate number of pan lysimeters to <br /> determine percolate quality in areas unaffected by wastewater application as well as in <br /> areas to which wastewater is applied. The workplan shall be consistent with, and <br /> include the items listed in, the first section of Attachment D, "Items to be Included in a <br /> Monitoring Well/Lysimeter Installation Workplan and Installation Report of Results." <br /> C. At least 60 days prior to allowing stormwater to bypass the 84-million gallon storage <br /> pond, the Discharger shall submit a technical report that describes specific numerical <br /> water quality criteria to determine if the bypass of stormwater around the storage pond <br /> is protective of surface water quality. Upon approval of the Executive Officer, <br /> wastewater that is consistent with the criteria may be discharged past the 84-million <br /> gallon storage pond. The discharge must remain in compliance with all stormwater <br /> permit requirements. <br /> d. By 31 March 2003, the Discharger shall submit a BPTC Salinity Source Reduction <br /> Plan for each waste constituent. The report shall describe each process that generates <br /> wastewater, the estimated daily flow for each waste stream, and chemical <br />
