H. Discharge of Water into an Underground Mina <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 O1 added 1,235 acres to the <br />original permitted area for a total of 2,823 acres prior to <br />1993.
