precipitation to the subsurface. There is no evidence of any significant <br />ground water recharge to the site from the Ennis Draw fluvial ground water <br />system. Ground water elevations in the sampled Ennis Draw wells close to <br />the Keenesburg Mine site are significantly higher than in either the spoil <br />monitoring well (SMW-2) or in the ash monitoring wells (AMW-1 or <br />AMW-2). <br />It is CEC's position that no adverse affect on the overall hydrologic balance <br />of the Keenesburg Mine site will result from, a continuation of the ash <br />disposal operation, from the limited addition of mine waste rock to the B -Pit <br />ash disposal, or from the continuing reclamation operations. Ground water <br />levels in the former coal extraction areas should be expected to recover to <br />their approximate pre -mining levels following the conclusion of all CEC <br />operations (see McWhorter report, Appendix I-1 to Permit C-81-028). <br />Treatment of either the ground water or the surface waters at the <br />Keenesburg Mine site is not anticipated to be necessary. <br />Notice: In the course of applying for, and obtaining approval to dispose of <br />mine waste rock in the ash disposal pit (B -Pit) at the Keenesburg Mine site, <br />CEC submitted, and received CDPHE approval for, a Ground -Water <br />Monitoring Plan. As a requirement of the approval, CEC is providing <br />notice that the data developed under the Monitoring Plan for 2011 has been <br />placed in the operating records at the site office. This is the fifteenth such <br />notice relative to the Ground -Water Monitoring Plan. <br />61 <br />
