The access to the pumps leading to 132132 is permanently sealed with the <br />sealing of the West District. A representative D2B data from the 2013 dewater borehole is <br />presented here. No issues have been encountered with respect to the analytical results. <br />SC -I 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.
