<br />' further effects of mining should be realized in the Pit #1 area. As a result, in October 1990 CMLRD <br />approved Technical Revision 04 to the permit which eliminated the requirement to monitor these wells. <br />Well 7, located in the reclaimed area, was dry from 1981 through 1984 samplings, however, has had water <br />since then. Water level in Well 7 may indicate the development of a spoils aquifer which may be due to the <br />general increase of pit water in the adjacent up dip Kerr Surface Mine which is currently being reclaimed. <br />' All monitoring data collected is exhibited on the attached Figure and Data Tables. TR-04 approved in <br />October 1990 eliminated the requirement to monitor water quality of this well. Water level data will continue <br />to be collected during an annual sampling in September. <br />NPDES SAMPLING <br />Surface water runoff from the disturbed areas of the mine was passed through one of the three <br />sedimentation ponds prior to discharge. NPDES reports were filed with both the Water Pollution Control <br />Division of the Colorado Department o[ Health and CMLRD. No discharges were made during the 1990 <br />monitoring period. <br />1 <br />,' <br />1 <br />1 <br />1 <br />1 <br />
