T <br />Nla)- 29. 201 8 <br />Mr. Eric Scott <br />Division of Reclamation. Mining, and Safety <br />Colorado Department of Natural Resources <br />1313 Sherman Street, Room 215 <br />Denver. Colorado 80203 <br />Re: Status of TR05 Corrective Actions - Mine Permit ?4-2008-082 <br />Dear Eric: <br />Please find enclosed the monitor well data through 5f2-12018 for the A&W Monitor Well and <br />MW -107 located north of the Stage 613 Pit. To date, the water levels in the A&W Monitor well <br />have recovered to the elevation measured last summer. We will continue to check the levels in <br />these wells to determine the effectiveness of the Containment Berm constructed in Stage 68, but <br />believe that we have minimized the impact of Stage 6 on the hydrologic balance. <br />At this time, we believe the water levels have recovered enough to allow the A&W Well to <br />operate without any impacts. A&W has confirmed this to us in informal communications. <br />Nevertheless, to determine the water level and productian status of the A&W Well. we hate <br />been in contact with A&W Water's Attorney, Wes Knc11. and their Water Engineer, Jason <br />Henderson, to schedule a time to conduct a second pun• p test on the well. We expect the test to <br />be completed on or around the 20" of June. We "ill fon%ard the results of the test to you once <br />that is completed. <br />In addition, we commissioned Deere and Ault Consultants, Inc. of Longmont, Colorado to <br />complete the stability analysis of the existing Containrrent Berm in Stage 6B (see attached scope <br />of work), If needed, they will make recommendations 'or the design of the berm should it be <br />necessary to raise the berm to further improve .cater levels in the area. At this time, it appears <br />that the heightened berm may not be necessary either For hydrologic balance purposes or to allow <br />A&W to use its well at the permitted pumping rate. In any event, the drilling of the berm was <br />completed on 5?23!2018. We expect the results of the Stability Analysis to be complete by the <br />end of June. When that is received, we will issue a follow-up report to communicate the results <br />of their analysis. <br />If you have an) questions or need additional information please let me kno%%. <br />Thank y ou, <br />�rr ......... <br />Joe Lamanna <br />General Manager - AgoreQates <br />Read) NINed Cnnerete Company, 11778 1 52, Fort Lupton.
