It is CEC's position that no adverse affect on the overall hydrologic balance of the <br />Keenesburg Mine site will result from, a continuation of the ash disposal operation, <br />from the limited addition of mine waste rock to the B -Pit ash disposal, or from the <br />continuing reclamation operations. Ground water levels in the former coal <br />extraction areas should be expected to recover to their approximate pre -mining <br />levels following the conclusion of all CEC operations (see McWhorter report, <br />Appendix I-1 to Permit C-81-028). Treatment of either the ground water or the <br />surface waters at the Keenesburg Mine site is not anticipated to be necessary. <br />Notice: In the course of applying for, and obtaining approval to dispose of mine <br />waste rock in the ash disposal pit (B -Pit) at the Keenesburg Mine site, CEC <br />submitted, and received CDPHE approval for, a Ground -Water Monitoring Plan. <br />As a requirement of the approval, CEC is providing notice that the data developed <br />under the Monitoring Plan for 2011 has been placed in the operating records at the <br />site office. This is the fifteenth such notice relative to the Ground -Water <br />Monitoring Plan. <br />LIST OF MONITOR WELLS <br />This table summarizes monitor well information, to include: well designation, top of <br />casing elevation, location, and aquifer monitored. The wells monitored during 2015 <br />were: <br />
