k4 KLEINFELDER I` 8. PROCESSING WASTE/DETENTION POND 6. As requested by Mr. Mike Huggins of SJCEHD, this section provides some additional information regarding the processing waste at the California Nuggets facility. According to Mr. L Trickey, the detention pond located at the northwest comer of the facility has an approximate capacity of 404,000 gallons and is used for the storage of water from corn peeling, steeping, and cooking operations. This water contains small amounts of starch, citric acid, and lime. 6. According to Mr. Trickey, the exact amounts of these constituents are unknown at this time and no analytical data has been provided to our firm. The approximate water usage at the facility is 160,000 gallons/month. In addition to the commercial water drained to the pond, stormwater runoff during the winter months is also diverted to the pond. The monthly/yearly amount of stormwater runoff is unknown at this time. The water in the pond reportedly can be used for irrigation of the almond trees after being blended with fresh well water. 9. CONCLUSIONS As shown above, we calculate 2.4 mg/1 of nitrate-nitrogen (N) in groundwater resulting from the existing leach fields, a result that is below the state standard of 10 mg/l. Based on this relatively low level of nitrate-nitrogen, we anticipate that the impact on surrounding wells will be minimal. As the detention pond is down gradient from the existing septic systems, we do not anticipate that any discharge into the pond would have an impact on the existing septic systems. The Stanislaus River is the nearest natural water body to the site and is located approximately 2 miles south of the site, but is generally not down gradient. Based on this distance and the relatively low nitrate-nitrogen levels calculated, we anticipate that the pact to water bodies will be �. minimal. �� G The results of our percolation tests mdlcate that a suitable soil percola�trr t exists at each test location at depths of between 3 and 3 %2 feet below existing site grade. A suitable soil condition for septic percolation tests is defined as a stratum capable of percolating water at a rate of 60 minutes per inch (min/inch) at a depth of up to 3.5 feet below existing site grade. Based on these results, it is our professional opinion that the existing permitted septic tank/leach trench sewage disposal systems should adequately serve the facility, provided they are appropriately Lsized for the facility. 10. LIMITATIONS L The conclusions of this report arc based on the information provided regarding the existing development and on the site conditions. It was assumed that the percolation test results are representative of the subsurface conditions in the general area. 6. 31917.GO1/ST03R1695 November 11,2003 ©2003 Kleinfelder,Inc. Page 6 of 7 L
