Revised, January 1985 <br />for total dissolved solids and total suspended solids at the inflow <br />points; and cfor total dissolved solids, total suspended solids, total <br />iron and total manganese, along with oil and grease when visually present <br />at the discharge points. Data from discharge points will be included in <br />the quarterly Discharge Monitoring Reports under NPDES Permit CO-0027154. <br />Trap efficiencies will be computed utilizing data on TSS collected simul- <br />taneously at inflow and outflow points. Data from effluent monitoring <br />sites 24 and 76 will be included in the Annual Hydrologic Monitoring <br />Reports. <br />The list of analyses to be performed on sull-suite groundwater and <br />surface water samples is based on a revised guideline issued by the <br />Colorado Mined Land Reclamation Division. Table C, Revised Parameter <br />List, delineates the analyses to be performed on groundwater and surface <br />water samples. The analyses performed on water samples from designated <br />sites will be included in the Annual Hydrologic Monitoring Report. <br />In addition to the existing ground water monitoring installations, <br />two spoil aquifer monitor wells will be installed and monitored when <br />backfilling and final grading are completed. The two wells, designated <br />008-SP-4 (Middle Creek Mine) and 008-SP-5 (Mine No. 3), shown on. Map 4a, <br />Mine No. 3 Hydrology, will be located at the deepest end of each pit, <br />where saturation is most likely to be present. The spoil monitor wells <br />will be monitored and sampled on the same schedule as deep aquifer moni- <br />tor wells, as shown in Table B. <br />-4a- <br />
