A total of 860 <br /> gallons (29.7 GPD) were evacuated from the leak detection system and pumped to the LTF. The LTF <br /> underdrain system flow was measured to be approximately 34.0 gallons per minute(gpm). <br /> West Pit Waste Water Treatment Plant <br /> During the month of November 2018, the West Pit Water Treatment Plant was operated under Colorado <br /> Department of Public Health and Environment(CDPHE)CDPS Permit No. C00045675 for discharge into <br /> the Rito Seco alluvial aquifer. During the month of November, 6,233,900 gallons (19.13 acre-feet) of <br /> treated water was discharged to the Rito Seco. There was 769,800 gallons (2.36 acre-feet) of water <br /> transferred from the West Pit to the LTF in November 2018. There was no sludge transferred from the <br /> water treatment plant drying pad to the LTF. <br /> BMRI performed the monthly visual seepage expression inspections on November 29,2018 in the historic <br /> seepage area identified in Figure 2 of the permit. No seepage expressions were observed in the historic <br /> seepage area during November 2018. <br /> BMRI measured the monthly West Pit backfill, alluvial and monitoring wells as required under in the <br /> QA/QC Plan. Measurements obtained for the monthly wells are shown in Table 3. <br /> Table 3-Monthly and Quarterly Groundwater Depth to Water <br /> Monitoring Well Identification Observation Date Depth to Water <br /> ft <br /> BF-4 11/29/2018 24.89 <br /> BF-5R 11/29/2018 30.82 <br /> BF-6 11/29/2018 30.92 <br /> M-6 11/29/2018 DRY <br /> M-7 11/29/2018 DRY <br /> M-8 11/29/2018 DRY <br /> M-9 11/29/2018 141.68 <br /> M-10 11/29/2018 25.59 <br /> M-11R 11/29/2018 38.22 <br /> M-12 11/29/2018 175.09 <br /> M-13R 11/29/2018 125.81 <br />
