The general ground water gradient, to the extent that it can be documented in <br />die spoil area on the Keenesburg Mine property, still trends downgradient to <br />the east. Recharge of the aquifer in the "spoil area" continues to be limited to <br />a single source, the localized infiltration of precipitation to the subsurface. <br />There is still no evidence of any significant ground water recharge to the site <br />from the Emus Draw fluvial ground water system. Ground water elevations in <br />those existing Ennis Draw wells close to the Keenesburg Mine site continue <br />to be significantly higher than in either the spoil monitor well or the ash <br />monitor wells. <br />CEC continues to believe that no adverse affect on the overall hydrologic <br />balance of the Keenesburg Mine site will result from the continued ash <br />disposal operation (or the addition of mining wastes to the ash disposal) <br />a~id/or the reclamation operations, and that ground water levels in the former <br />mined areas would be expected to recover to approximately their pre-mining <br />levels following the conclusion of CEC operations (see McWhorter report, <br />Appendix I-1 to Permit C-81-028). CEC does not anticipate that it will be <br />necessary to treat either ground or surface waters at the Keenesburg Mine <br />site. <br /> <br /> <br />AIItt-1997 -42- Stipulation #5 <br />
