H. Discharge of Water into an Underground Mine <br /> At the time of this permit renewal, water has not been <br /> diverted or discharged into any underground mine in <br /> conjunction with on-going mining and reclamation activities at <br /> the Southfield Mine. <br /> However, the Division approved Technical Revision No. 19, as a <br /> response to Stipulation No. 20, which outlines plans for a <br /> closed-loop system within the Southfield Mine. Water will be <br /> pumped from one area of the mine and discharged via a pipeline <br /> to previously abandoned workings within the mine. This <br /> revision was approved on 24 October 1994 . <br /> I. Stream Buffer Zones <br /> There are no perennial streams or surface drainages in the <br /> Southfield Mine area or loadout that support significant <br /> biological communities . <br /> J. Probable Hydrologic Consequences <br /> Ground Water Description and Consequences <br /> The permitted area lies on the southern terminus of the <br /> Chandler Syncline, where the Southfield Mine is currently <br /> mining the Red Arrow and the Jack O 'Lantern seams of the <br /> Vermejo Formation. <br /> Groundwater resources in the permit and adjacent areas are <br /> limited in extent due to lenticular lithologies of the <br /> potential water-bearing units and because of previous <br /> underground coal mine dewatering. Three adjudicated wells <br /> were identified within the permit and hydrologically adjacent <br /> areas : the Corley Mine Well, the Corley Company Well and the <br /> Thompson Well . The Corley Mine Well produces water from mine <br /> workings in the Vermejo Formation. The Corley Company Well <br /> produces from the Raton Formation. The Thompson Well is <br /> within the permit area and was developed in a localized coarse <br /> gravel lens on top of sandstone above the Rex Carbon Seam. <br /> The operator has collected baseline ground water data for the <br /> newly permitted area through Permit Revision 1, approved in <br /> March of 1991 . Permit Revision 01 added 1, 235 acres to the <br /> original permitted area for a total of 2 , 823 acres prior to <br /> 1993 .
