and are located on Plate 1. Table 14 lists the discharge amounts for the <br />period of record that started February. 1985. <br />Water quality data for Pond No. 2 have been analyzed since January. 1985. <br />are presented in Table 15. Also shown ie a single lab analysis for <br />discharge from Pond No. 5. No quality data are available for the single <br />discharge from Pond No. 1. <br />' Examination of data from Pond No. 2 indicate that discharges averaged 2.03 <br />mg/1 total iron and 46 mg/1 total suspended solids. The discharge permit <br />requires that the limitations for total iron to be 3.5 mg/1 for a 30-day <br />average and 7.0 mg/1 as a daily maaimum; total suspended solid limitations <br />are 35 mg/1 for a 30-day average and 70 mg/1 for the daily maximum. The <br />data for Pond No. 2 show that. of the 24 samples analyzed. the daily <br />maximum for total iron was exceeded only on October 11. 1985. The total <br />iron content of the discharge water was 8.46 mg/1 on that date. The <br />average of 2.03 mg/1 for the 24 samples was under the limit of 3.5 mg/1. <br />The average for total suspended solids for 24 samples was 46 mg/1 and the <br />daily maximum was exceeded for four samples for the period of record. <br />![IPB WATSE I10?LOW9 <br />Mine inflows are estimated to be 142.5 acre-feet per year. based upon <br />adjusted records to reflect the full calendar year for 1985. This <br />estimate is based upon adjusted pumping records for three locations used <br />for dewatering of the mine. Actual pumping records are summarized in <br />Table 16. The adjusted amounts are 141.91 acre-feet for the North Entry <br />Well. 0.45 acre-feet for the North Sump Pump and 5.26 acre-feet for the <br />Fan Pump, for a total of 147.62 acre-feet for 1985. The amount of water <br />brought into the mine for use was 5.13 acre-feet. metered at the <br />Onderground Meter and adjusted for a complete year. This amount should be <br />deducted from the total dewatering amount pumped. resulting in an annual <br />mine inflow estimate of 142.5 acre-feet for 1985. <br />- 4 - <br />
