INTERNAL MEMO <br />TO: Jim Stark 1 Apri12004 <br />FROM: Jim Bur <br />SUBJ: Deserado ( -1981-018) 2003WY AHR Review <br />The review of the Deserado 2003 AHR has been completed. The report is satisfactory <br />and meets the operator's obligations. <br />A review as per the predictions made in the PHC. <br />(1) PHC: Very little water will be pumped to the surface from the underground <br />mine. <br />This prediction was accurate. According to the AHR, no water has been pumped to the <br />surface since the fire in January, 1996. <br />(2) PHC: Gronndwater inflow into the mine will be very low. <br />A statement is made in the AHR that the mine is essentially dry. This prediction appears <br />to be accurate. <br />(3) PHC: Mine inflows are predicted to not exceed 5 to 10 gpm. <br />The Division requested inclusion of mine inflow data in the AHR in last year's review. <br />On page 9 of the report, a statement appears indicating that water is pumped from the D- <br />seam mine For storage at the rate of 8 gpm. This may represent the figure for inflow. If <br />so, the prediction in the PHC is accurate. Whatever the case, the Deserado Min is a very <br />dry mine. <br />(4)PHC: The local groundwater table may be lowered as mining proceeds. <br />This has apparently occurred. The water level in bedrock monitoring wells has dropped <br />as mining activity approached and the wells have gone dry as mining has passed. <br />
