Restoration of <br />ground water Surface facilities and underground workings of the Foidel Creek Mine lie downhill from <br />rechar a to CDMG regulation es the outcrop belt that rims the Twentymile Park Syncline. Ground water is recharged in <br />appro mate 4.05.11(3) y this outcrop belt. The mine has not disturbed the rocks in this outcrop belt and, <br />reminin rate consequently, does not diminish the amount of recharge. <br /> Compliance with the Basic Standards for ground water, as explained in item G, above, <br /> indicate the pennittee is preventing adverse impacts to ground water quality outside the <br /> permit area. Monitoring data indicate the permittee is preventing impacts to water quantity <br /> outside the permit area. Mining has dropped the potentiometric surface of the Wadge <br />N.

Pumping for <br />the permit area mine use is probably the cause of a drop of few hundred feet in the potentiometric surface <br /> of the Trout Creek Sandstone at the mine's Trout Creek Sandstone wells 001-83-106 and <br /> 001-83-107.
