Alluvial wells 1 through 9, 11, 12 and 14 through 17 will be monitored <br />quarterly for field parameters. A full suite sample will be obtained semi- <br />annually during the second and fourth quarters. <br />Culverts 1 through 4 were monitored quarterly for field parameters. A full <br />suite sample from List 1 was to be obtained semi - annually during the second <br />and fourth quarters. Technical revision #59 demonstrated vegetation was <br />established on the outslopes of the unit train loadout and sedimentation <br />control other than vegetation was not required. Therefore, after the May <br />2009 approval of technical revision #59, monitoring of culverts 1 through 4 is <br />no longer necessary. <br />The sediment ponds will be monitored in accordance with discharge permit <br />requirements. During August of each year a sample will be obtained and <br />analyzed for the parameters on List 2 if the sediment ponds discharge. <br />Mine inflows will be measured semi - annually for field parameters. An annual <br />full suite analysis will be obtained for any point source of inflow greater than 5 <br />gallons per minute. Results of the mine inflow monitoring including a seep <br />location map and seep rate of flow will be submitted with the annual <br />hydrologic report. During the development of the main entries under Terror <br />Creek, mine inflows will be measured and reported to the DRMS quarterly. <br />When the main entries under Terror Creek are complete, mine inflow <br />monitoring frequency will revert to semi - annually. In the west mining area <br />mine inflow and reporting will be used to substantiate dry conditions up <br />gradient and to further evaluate the need for additional monitoring. <br />Small area exemptions shown on Map 20 will be monitored quarterly. The <br />Applicant will use its best efforts to obtain samples. The samples will be <br />analyzed for pH, conductivity and total settleable solids. Samples will be in <br />compliance if they contain settleable solid levels of 0.5 ml /I or less and the pH <br />is greater than 6.5 and less than 9.0. <br />The following pages list the water monitoring stations. <br />PR -14 2.05-127 09/12/14 <br />
