2.05 APPLICATION FOR PERMIT FOR SURFACE OR UNDERGROUND ACTIVITIES -- <br />MINIMUM REQUIREMENTS FOR OPERATION AND RECLAMATION PLANS. <br />2.05.6 Mitigation of Surface Coal Mining Operation Impacts. (Cont'd.) <br />(3) (b) (ii) (Cont'd.) <br />The entire operations of the Bowie No. 1 Mine and the Bowie No. 1 West Mine are designed to <br />protect surface and groundwater from adverse effects. Both are monitored on the disturbed site, as <br />well as on the permit and adjacent areas. As discussed in Sections 2.05.6(3)(a)(iii), stipulations <br />attached to the Operator's FCL C -37210 require that existing on4ract and cross -tract flows be <br />protected from the effects of subsidence by limiting coal extraction in buffer zones established by the <br />BLM under Steven's Gulch and East Roatcap Creek, by formulatinga water replacement plan for <br />the repair of conveyance of storage systems and the replacement of any water' lost from an <br />adjudicated water right, and by maintaining flows for future use. <br />This plan of collection, recording, and reporting of ground and surface water quality and quantity <br />data is discussed as follows: <br />Surface Water Monitoring - Orchard Valley and Orchard Valley West Mine Sites <br />Surface water monitoring at the Operator' Bowie No. 1 Mine includes quality and quantity <br />measurement for discharges from disturbed lands. Speck parameters are measured in <br />accordance with the Operator's NPDES Discharge Permit at six NPDES discharge points upon <br />l release of flows from the disturbed areas to a natural water course. <br />J The surface runoff from disturbed areas at the portals and support facilities throughout the property <br />is totally contained within the existing sedimentation systems. Surface water is discharged and <br />monitored at sedimentation pond #4 (Outfall 002), the timber storage area sedimentation pond <br />(Outfall 003), the coal stockpile sedimentation pond (Outfall 004), the train loadoutsedimentation <br />pond (Outfall 005), and the West Mine sedimentation ponds (Outfall 006). Refer to the NPDES <br />Appendix in Volume 8A for speck information on the NPDES permit. <br />The storage capacity of the sedimentation ponds at discharge points 003, 004, 005, and 006 results <br />in infrequent discharges. Appropriate sampling analyses are conducted in the event discharge <br />occurs. <br />Required NPDES parameters include flow, total iron, total dissolved solids, total suspended solids, <br />and pH. Conditional analysis for oil and grease are also required if a visible sheen is evident on the <br />discharge. Discharge Monitoring Reports (DMR's) are filed quarterly with the Division in accordance <br />with Rule 4.05.13(2)(a)(iii), and are available for inspection by the Regulatory Authority at the <br />Operator's mine site office. Any samples which indicate a permit violation will be reported <br />immediately to the Regulatory Authority. <br />Surface water discharge monitoring will continue for such time as is deemed necessary after <br />cessation of use of underground mine workings and after surface disturbed areas have been <br />regraded and stabilized. All equipment for monitoring will be removed when it is no longer required <br />for monitoring. <br />Groundwater Monitoring - Bowie No. 1 Mine and the West Mine Site <br />The Bowie No.1 Mine East and West Mines are located several hundred feet above the watertable <br />of the area. The mines are designed to prevent toxic materials or leachates from contacting water <br />sources. <br />SkOCIL6 BE <br />)R-1L PR_04 <br />0 1/13/1) <br />
