additional 3 . 5 acres was added to the permit for a total of <br /> 2 , 826 . 4 acres . Technical Revision 25 , approved 10 October, <br /> 1, 996, removed 84 . 8 acres from the permit area . The current <br /> permit encompasses 2 , 735 . 6 acres . The wells used to <br /> accumulate baseline data serve to monitor both water quality <br /> and quantity effects before the effects extend to the wells to <br /> the north of the permitted area, in the direction of <br /> subsurface flow. If in the future, data suggest that drawdown <br /> to the Corley wells is occurring, the operator may be required <br /> to install additional monitoring wells closer to the wells of <br /> interest and meet the requirements of Rule 4 . 05 . 15 pertaining <br /> to water rights and replacement . <br /> The Corley Company Well is located approximately 800 feet from <br /> the permit boundary, which coincides with the affected area <br /> boundary, and its completion zone in the Raton Formation is at <br /> least 400 feet stratigraphically above the coal seams that <br /> were mined. Drawdown effects to the Corley Company Well would <br /> 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 /> and recycling it 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 . The <br /> total depth of the well is 338, into the Rex Carbon coal seam, <br /> although the source of water is a thin unit above sandstone at <br /> 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. The <br /> casing at the surface has been obstructed; consequently, both <br /> mine and Division personnel have been unable to detect any <br /> water level within the casing. Available information on the <br /> well indicates it is, at present, abandoned. Extensive <br /> drilling adjacent to this area by the operator did not reveal <br /> any laterally continuous aquifer that could serve as a <br /> regional water source . <br /> Southfield Mine Permit Renewal 03 <br /> 40 <br />
