Mr. Elliott R. Russell <br /> October 9, 2017 <br /> Page 2 <br /> provided them with a water level indicator for future measurements. Fremont will do the future <br /> field measurements and send results to D&A annually for review and submittal to the Division. <br /> The monitoring results are presented on Table 1 and a map of the monitoring wells is shown on <br /> Figure 1. The monitoring plan as represented in AM-01 was closely replicated. Some of those <br /> wells never existed, were located improperly, or were destroyed. Nearby wells to those <br /> originally proposed were substituted as necessary as shown on Table 1. <br /> Monitoring Hole No. 1 (279124) is the closest upgradient well to the Phase 1 cell on the former <br /> Southwest Farms property. The current water level in this well is 10 feet below ground surface. <br /> This has risen 5 feet since it was constructed in August of 2008. When the well was built, Phase <br /> 1 of the Pueblo East Pit was dewatering for mining. <br /> A more complete discussion of groundwater conditions, including the results of a 3-D model are <br /> provided in our response to the Technical Revision (TR-4), Adequacy Review. <br /> CLOSING <br /> Fremont and Stonewall,with D&A's assistance,will provide water level monitoring for the <br /> wells shown on Figure 1 through the life of the permitted mine. This will be conducted monthly <br /> until dewatering is shut-off for Phase 1 and then be converted to quarterly measurements. <br /> The information above indicates there appears to have been no injury due to the oversight of not <br /> performing the voluntary plan for groundwater monitoring. In addition, Southwest did not <br /> request the monitoring results from Fremont or Stonewall. <br /> Please call with any questions or comments. <br /> Sincerely, <br /> DEERE & AULT CONSULTANTS, INC. <br /> Don W.
