Eochhead <br />Executive Director <br />Michael B. Long <br />Division Director <br />I have reviewed the hydrology monitoring plan for the Canadian strip mine and I believe that <br />stipulation #32 is no longer necessary. Stipulation #32 was applied to the 1987 permit renewal and <br />requires the mine to submit an annual water level measurement for water monitoring well #7 by <br />October 31 of each year. <br />STIPULATION NO. 32 <br />THE HYDROLOGIC MONITORING PLAN WILL CONSIST OF MONITORING THE <br />SPOII,S WELL ANNUALLY FOR WATER LEVEL AND TO SUBMIT THE RESULTS <br />TO THE DIVISION BY OCTOBER 31 OF EACH YEAR. <br />Slurco Corporation, the operator of the Canadian strip mine, has been taking annual water level <br />measurements, but in the past two years has submitted this data after October 31. This data had been <br />submitted with the annual hydrologic report. This constitutes the water monitoring program for the <br />mine. <br />The original purpose of the stipulation was to get water level data to the Division as soon as <br />possible. This was necessary so that the hydrologist could make an early evaluation of the recovering <br />spoils aquifer. The data that has been collected for the past 8 years show that water level <br />measurements have stabilized and are now at equilibrium with annual precipitation (see chart below <br />from the DM&G annual hydrologic report review). <br />
