i <br /> INFORMATION SHEET <br /> MUSCO OLIVE PRODUCTS, INC. AND <br /> THE STUDLEY COMPANY <br /> WASTEWATER DISCHARGE TO LAND <br /> SAN JOAQUIN COUNTY <br /> Musco Olive Corporation proposes to expand wastewater reclamation disposal areas from <br /> 4.5 acres to 200 acres for land application of olive process production water. The <br /> reclaimed water will be used for irrigation of crops selected to uptake the discharged water. <br /> The typical existing flow is 200,000 gpd and is proposed to increase to 500,000 gpd as the <br /> olive processing factory expands. <br /> Perched ground water is found at the facility at 29 feet below ground surface(bgs). Onsite <br /> wells do not encounter ground water 90 feet bgs. An onsite production well encountered <br /> artesian water at 250 feet bgs with a static head at 50 feet bgs. <br /> Ground water samples collected in 1985 from the perched zone contained 920 mg/1 TDS, <br /> 32 mg/l chloride, and 264 mg/1 sodium. The Musco Olive#1 production well encountered <br /> artesian water at 250 feet bgs with a static head at 50 feet bgs. Based on a single sampling <br /> event in February 1996, water quality for this well showed chloride (514 mg/L), sulfate <br /> (400 mg/L), sodium (477 mg/L), total dissolved solids (1434 mg/L), electrical conductivity <br /> (2240 µmhos/cm), and a pH of 7.8. This well will be monitored for background water <br /> quality. The discharger proposes to spray irrigate reclaimed water that contains an average <br /> of 1280 mg/1 TDS, 456 mg/1 sodium, and 228 mg/1 chloride. <br /> The Discharger will monitor the quality and application rate of wastewater to field and row <br /> crops. Application rates will be less than the infiltration rate and storage capacity of the soil <br /> in order to prevent surface water runoff. <br /> The Discharger will also monitor surface water runoff and take soil samples to analyze <br /> buildup of constituents in the soil over time. Surface water runoff from the upper parcel <br /> goes under culverts in the railroad embankments. It then commingles with the surface <br /> water runoff on the lower parcel. This water combines into one stream channel which <br /> passes diagonally through the lower site and exits the facility and flows under Highway <br /> 580 near the lined ponds into an unnamed, dry creek bed. <br /> KAS <br />
