Culverts 1 through 4 were monitored quarterly for field parameters. A full suite <br />sample from List 1 was to be obtained semi-annually during the second and fourth <br />quarters. Technical revision #59 demonstrated vegetation was established on the <br />outslopes of the unit train loadout and sedimentation control other than vegetation <br />was not required. Therefore, after the May 2009 approval of technical revision #59, <br />monitoring of culverts 1 through 4 is 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 analyzed <br />for the parameters on List 2 if the sediment ponds discharge. <br />Mine inflows will be measured semi-annually for field parameters. An annual full <br />suite analysis will be obtained for any point source of inflow greater than 5 gallons <br />per minute. Results of the mine inflow monitoring including a seep location map and <br />seep rate of flow will be submitted with the annual hydrologic report. During the <br />development of the main entries under Terror Creek, mine inflows will be measured <br />and reported to the DRMS quarterly. When the main entries under Terror Creek are <br />complete, mine inflow monitoring frequency will revert to semi-annually. In the west <br />mining area 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 Applicant <br />attempt to obtain samples. The samples will be analyzed for pH, conductivity and <br />total settleable solids. Samples will be in compliance if they contain settleable solid <br />levels of 0.5 ml/I or less and the pH is greater than 6.5 and less than 9.0. <br />The following pages list the water monitoring stations. <br />TR -103 2.05-127 05/15 <br />
