AHR Adequacy for 2020 Report year. <br /> 1. Please verify that water level was measured for well 259 in 2020 or,explain why it was not <br /> measured. If measurements were conducted,please provide the data as revised pages to the 2020 <br /> AHR. Also,assure that water levels are monitored as stipulated in the permit. <br /> 2. Figure 2 the monitoring locations map was missing from the submittal. <br /> 3. Table 3A of the WF permit lists Yampa River Alluvium and surface water monitoring sites; <br /> specifically the YAW wells 1,2, 5 and 6,as well as surface water sites Y1 and Y2. These <br /> monitoring locations are not listed on Table 1B of the AHR. Please explain the monitoring status <br /> of the above mentioned monitoring points and why they were not monitored in 2020. DRMS <br /> notes that alluvial wells AVF wells 3 through 5 were monitored in 2020. Please provide DRMS <br /> with the correct sampling frequency for these wells, and update the permit with revised pages. <br /> Also assure that and future AHR submittals include the above mentioned wells in sampling data. <br /> 4. As per Table 8 of the Williams Fork permit DRMS finds that total Hardness constitutes a sampled <br /> parameter. DRMS finds that was omitted from monitoring in 2020 and is not listed in the suite of <br /> monitored analytes on Table 3B of the 2020 AHR. Going forward please assure monitoring for <br /> hardness and update the analytes list requiring monitoring on the appropriate AHR tables. <br /> 5. MCM needs to be timely in submitting surface water monitoring information,and sediment pond reports <br /> to The Division. <br />
