Annual <br />Hydrology Reports are stand alone documents containing, the methods and <br />results of all monitoring activities. In addition, monitoring has been conducted in <br />accordance with the NPDES Permit as described in Exhibit 22, NPDES Permit, <br />and summarized in the Annual Hydrology Reports. <br />Current and historic monitoring locations are generally described below: <br />NE -001-G: A grab sample station from the New Elk Mine remediation system <br />permitted under the NPDES Permit No. COG -310069. The station was <br />established to monitor water discharging from the UST facilities area. NE -001-G <br />is sampled at its outfall prior to discharging into D-16, which flows into pond <br />007, a site monitored under NPDES Permit No. CO -0000906. <br />NE -004: Grab sample of the discharge from the primary spillway of sediment <br />Section 2.05 RN -6 Repaginated 10/21/16 <br />
