2. The applicant demonstrated that surface water monitoring was no longer <br />necessary and the Division approved the termination of surface water <br />monitoring as documented in the SL -06 bond release written findings (August <br />2008) (4.05.13(2)): <br />C. Probable Hydrologic Consequences <br />The probable hydrologic consequences concerning ground water of the Golden <br />Eagle mine were detailed for active mining operations and post -mining conditions. <br />Due to the Golden Eagle Mine now being in a reclaimed condition, the ground <br />water probable hydrologic consequences are detailed for the post -mining condition <br />only and are as follows: <br />• Reduction of ground water discharge to streams <br />• Reduction of overburden spring flow <br />• Ion changes in the ground water system <br />After mine closure, flooding of the existing workings will occur. Until the pre - <br />mine static water level in the aquifer is re-established, discharge via the natural <br />discharge point will be subdued. The Purgatoire River is the likely discharge <br />recipient, probably near the center of the Raton Basin. The same situation would <br />hold true for any springs in the overburden, which exist where drainages have <br />intercepted the piezometric surface of the overburden aquifer. Until the <br />overburden aquifer re -saturates to approximate pre -mine levels, flows from the <br />springs in the overburden will be reduced or cease entirely. <br />Subsidence fracturing and rubblization in the overburden could also cause <br />decreases in spring flows in the overburden. Subsidence after mine closure could <br />occur in areas over entries where subsidence was not projected during active <br />mining. It is likely that isolated subsidence would have minimal to negligible <br />effects on springs. <br />Upon flooding of the workings, the water quality in the coal seam and overburden <br />will be similar to water quality observed during mining. Some degradation of this <br />water will occur due to contact with rubblized gob and other mine areas. <br />IV. Topsoil <br />No specific approvals are granted under this section. <br />V. Sealing of Drilled Holes and Underground Openings <br />All openings have been permanently sealed, (4.07.3). <br />13 <br />
