2015 AHR Page 4 <br />pipe is presented on permit Figure 14-6. The capacity of this discharge pipe was about 75 gpm. <br />Flow ceased at discharge point 001 on March 31, 2002. Discharge point 001 was reclaimed <br />during the 1St quarter of 2008 and is no longer operational. <br />Discharge point 002 was water siphoned from the reclaimed Northwest Intake Portal at the <br />Roadside South Portals. Mine inflows that were not pumped to the preparation plant were <br />routed to an abandoned portion of the mine for discharge from this point. The preparation plant <br />was shut down during December 1999 so all mine inflows in excess of those handled by outfall <br />001, flow north to the lower portion of the mine where they were handled by the siphon, outfall <br />002. Flow ceased at discharge point 002 on March 31, 2002. <br />The following table presents the total dissolved solids concentration in Outfall 002. <br />Average TDS from Pages SE -8 = SE -11 Outfall 002 <br />Water Year <br />1999 <br />2000 <br />2001 <br />2002 <br />TDS (mg/1) <br />1558 <br />1560 <br />1500 <br />1500 <br />Discharge point 016 was put into service April 1, 2002. Discharge began April 3, 2002. This <br />gravity discharge point handles all of the water that flows into the sealed South Portal. Since it <br />is a gravity discharge point, the flow discharged will equal the flow into the mine. Table M15-1 <br />presents a summary of the monthly flow from the mine. Data page SV -14 presents a listing of <br />flow and water quality monitoring performed at this site during the Year. Data page SU -5 <br />includes a full suite analysis performed on a sample collected during the Year. The average <br />TDS value at discharge point 016 for the Year was 1260 mg/I. <br />Whole Effluent Toxicity (WET) tests were not performed during the Year. On May 3, 2005, <br />Snowcap Coal Company requested, via letter to the CDPHE, the WET tests be terminated. <br />This request was granted and the CDPS Permit was amended on June 27, 2005, becoming <br />effective on August 1, 2005. <br />Ground Water <br />The ground water monitoring points on Cottonwood and Rapid Creeks were monitored twice <br />during the Year. Results of the monitoring are listed on data page GA -2. Diagrams G15-1 thru <br />3 shows a graphical representation of the depth to water for these wells since monitoring began <br />in 1984. Table G15-1 was prepared to show average water levels in the spring and fall to <br />correspond with high and low water levels in the adjacent creeks respectively. <br />Piezometers CRDA-01 thru 06 at the Cameo Refuse Disposal Areas (CRDA) No. 1 and No. 2 <br />
