requirements of Rule 4.05.15 pertaining to water rights and <br />replacement. <br />The Corley Company Well is located approximately 800 feet <br />from the permit boundary, which coincides with the affected <br />area boundary, and its completion zone in the Raton Formation <br />is at least 400 feet stratigraphically above the coal seams to <br />being mined. Drawdown effects to the Corley Company Well <br />would not be expected to be present. Annual Hydrology reports <br />submitted since 1986 indicate no drawdown effect is occurring. <br />The Corley Mine Well is located approximately 1,400 feet from <br />the permitted area boundary. This well produces approximately <br />60 gpm from the abandoned workings of the Corley Mine. EFCI <br />has the rights to this water and uses the water in mining and <br />processing operations by pumping it to a storage pond (Pond 3) <br />where it can recycled through Pond 2. To date, no significant <br />drawdown effects have resulted from this use and none are <br />anticipated. <br />A well permit was issued for the Thompson Well in 1941. Total <br />depth of the well was 338 into the Rex Carbon coal seam, <br />although the source of water is a thin unit above a sandstone <br />at a depth of about 320 feet. Subsequently, the Rex Carbon <br />Underground Mine was developed beneath this area and <br />eventually encountered the well casing. A pipe was connected <br />to the well within the mine workings and water was routed to <br />the surface as a water supply for the Thompson Ranch. At <br />present, the pipe within the mine has been damaged. Also the <br />casing at the surface has been obstructed; both mine and <br />Division personnel have been unable to detect any water level <br />within the casing because of the obstruction. Available <br />information on the well indicates it is at present, abandoned. <br />Extensive drilling adjacent to this area by the operator did <br />not reveal any laterally continuous aquifer that could serve <br />as a regional water source. <br />Energy Fuels has mined the Jack O'Lantern seam about 380 feet <br />beneath the abandoned Rex Carbon Mine below the Thompson Well. <br />This area has also been mined under prior permits. The <br />Thompson Well has already been affected by historic mining in <br />the Rex Carbon and Jack O'Lantern coal seams. The Thompson <br />Well at this time is not serviceable for production or <br />monitoring of ground water. The operator is not predicting <br />any additional impacts to this well from their operation due <br />to their location below the well and intervening competent <br />sandstones. <br />The original Findings included a stipulation No.5 requiring <br />that the operator monitor water levels in the Thompson Well. <br />Because of the information outlined above, this stipulation is <br />no longer considered necessary. However, Energy Fuels has <br />agreed to comply with the Colorado Water Law if an injury from <br />their operation should occur to a valid active water right <br />holder. A series of mine dewatering wells have been installed <br />33 <br />
