SAE's No. 1-17. With the exception of the NW-1 ventilation shaft <br />SAE, all other areas have been final bond released (4.05.2(3)(b)(i)). <br />B. Stream Channel Diversions <br />No stream diversion remain within the permit area. <br />C. Surface and Ground Water Monitoring <br />1. The applicant demonstrated that ground water monitoring was no <br />longer necessary and the Division approved the termination of ground <br />water monitoring as documented in the SL-06 bond release written <br />findings (August 2008) (4.05.13(1)): <br />2. The applicant demonstrated that surface water monitoring was no <br />longer necessary and the Division approved the termination of surface <br />water monitoring as documented in the SL-06 bond release written <br />findings (August 2008) (4.05.13(2)): <br />D. Probable Hydrologic Consequences <br />The probable hydrologic consequences concerning ground water of the <br />Golden Eagle mine were detailed for active mining operations and post- <br />mining conditions. Due to the Golden Eagle Mine now being in a reclaimed <br />condition, the ground water probable hydrologic consequences are detailed <br />for the post-mining condition 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 <br />pre-mine static water level in the aquifer is re-established, discharge via the <br />natural discharge point will be subdued. The Purgatoire River is the likely <br />discharge recipient, probably near the center of the Raton Basin. The <br />same situation would hold true for any springs in the overburden, which <br />exist where drainages have intercepted the piezometric surface of the <br />overburden aquifer. Until the overburden aquifer resaturates to <br />approximate pre-mine levels, flows from the springs in the overburden will <br />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 <br />closure could occur in areas over entries where subsidence was not <br />projected during active mining. It is likely that isolated subsidence would <br />13
