Site, and Holt (248), located approximately 14.2 miles northeast of the Site. Data for <br /> the Ripon station were available for the past nine years; based on the calculation <br /> shown, the estimated rate of recharge from percolating waters for the Ripon station is <br /> determined to be 3.68 inches. An error of 55 percent is associated with this value (Plate <br /> 15). Data for the Holt station were also available for the past nine years; based on the <br /> calculation shown, the estimated rate of recharge from percolating waters for the Holt <br /> station is determined to be 3.99 inches. An error of 54 percent is associated with this <br /> value (Plate 16). The values for the two stations were then averaged, for an estimated <br /> rate of recharge of 3.84 inches. <br /> WRCC Tracy Pumping Plant and CIMIS Holt Stations <br /> For the WRCC data, the closest WRCC station is the Tracy Pumping Plant (station <br /> 049001), located approximately 5.2 miles northwest of the Site. WRCC does not track <br /> evapotranspiration; consequently, rainfall data from the Tracy Pumping Plant and <br /> evapotranspiration data from the Holt station (the closest San Joaquin County CIMIS <br /> station to the Tracy Pumping Plant) were utilized (Plate 17). Based on the calculation <br /> shown, the estimated rate of recharge from percolating waters for this station is <br /> determined to be 4.94 inches. An error of 63 percent is associated with this value. <br /> Live Oak then averaged the recharge rates from the CIMIS station calculation and the <br /> WRCC Tracy Pumping Plant station to arrive at a recharge value of 4.39 inches for the <br /> vicinity of the project Site. <br /> Quality of Rainwater <br /> Hantzsche and Finnemore listed 1 mg/L-N as the nitrate concentration of rainwater for <br /> their original calculation; in the past, Live Oak has also utilized this value for the nitrate <br /> loading calculation. <br /> To determine a more accurate local value, Live Oak has collected rainwater during 15 <br /> recent storm events in Lodi. Each sample was collected in a clean, dry, stainless steel <br /> bowl, then decanted into a plastic container and placed on ice for transport. The <br /> samples were analyzed for nitrate by FGL Environmental of Stockton. The results of <br /> the rainwater sampling are as follows: <br /> LOGE 2637 Page 10 <br />
