significantly from readings on April 8, 2011 and May 10, 2011. The water level went from 32.04 feet to <br />18.98 feet. The water level went down to 21.66 feet on June 8, 2011. It appears that the water level in <br />Monitor Well N has continued to drop through this quarter and was at 23.13 feet on September 8, 2011. <br />We were advised that the wash plants had produced approximately 133,185 tons of waste coal during the <br />month of July 2011: approximately 113,034 tons during August 2011: and approximately 113,981 tons <br />during September 2011. It is our understanding that the fines being produced at the wash plant, which <br />consists of approximately 10 to 20 percent of the total materials being produced, are being pumped <br />underground into the mine. <br />Based on our limited observations and compaction test results, it appears that the pile is currently being <br />constructed and maintained in general accordance with the project specifications and plans submitted under <br />2.05.3(8) and that the potential hazard to human life and property at the site in its present condition is <br />minimal. This report fulfills the quarterly inspection requirements as specified by Rules 4.09.1(11)(a), <br />4.09.1(11)(b), 4.10.2(2)(a) and 4.10.2(2)(b). <br />If you have any questions regarding tl/s report or our observations, please contact this office. <br />Sincerely, <br />NWCC, INC., <br />Timothy S.
