Flickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Virginia Brannon <br />Director <br />Annual Hydrology Reports (AHRs) for the King Coal Mine were received electronically by the <br />Division on July 26, 2011; July 25, 2012; and June 26, 2013. The A14R for each year is divided <br />into two separate documents — one each for the King I and King II Mines. The Division has <br />reviewed the AHRs submitted for 2011, 2012 and 2013 for compliance with the Rules and with <br />the requirements of the GCC's DRMS permit. Comments are provided below. <br />Rules 2.05.6( )(ivy end 4.05.13 (1) & (2) - Hydrologic MonUorinp Plans _ <br />Ground Water Monitoring <br />Kim <br />1. Twelve parameters are to be monitored for the King I Wiltse Well, an alluvial well <br />located downstream of the mine's surface facilities- The well has been sampled since <br />1982, and was sampled quarterly for each of the three subject years, in accordance with <br />2.04.7 p. 7. Data for each of the listed parameters was reported. <br />2. The AHRs do not indicate the laboratory method used for determination of Calcium, <br />Iron, Magnesium, Manganese, and Sodium concentrations. <br />With future AHRs, please indicate whether the results represent Dissolved or Total <br />concentrations. <br />3. The graph provided indicates that Conductivity has been increasing overall since <br />sampling first began in 1982. However, measurements of TDS do not reflect the same <br />trend. <br />Please include a written discussion of the observed results in future AHRs (see <br />comment (c)(iii), below). <br />office of Office of <br />Mined Land Reclamation Denver • Grand )unction • Durango Active and Inactive Mines <br />
