See also the discussion regarding the H-10 well where <br />that monitor well has remained dry. <br />Once a year, samples of water are taken of water transferred to D2B and D2B2 and summarized <br />as follows: No is;sues were encountered with respect to the analytical results. <br /> D2B D2B2 <br />Date H TSS H TSS <br />December 31, 2007 8.72 17 mg/1 8.49 14 mg/1 <br />June 13, 2006 8.58 12 mg/1 8.15 39 mg/1 <br />June 6, 2005 8.57 10 mg/1 NA NA <br />December 28, 2(104 8.53 6 mg/1 NA NA <br />SC-1 Well -Rollins Sandstone <br />Monitor well SC'-1 is located just east of the reclaimed Sanborn Creek mine portal area. <br />Well SC-1 was completed in the Rollins Sandstone, which is located 40 to 50 feet below the B- <br />Seam. Monitoring data were historically collected from well SC-1 prior to any substantial <br />mining in the B-Seam of the Sanborn Creek Mine. The SC-1 well is located up-gradient relative <br />• to the Rollins Sandstone unit which is located stratigraphically under the footprint of the mining <br />activities. <br />14 <br />
