§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 />(1) (b) (iii) (Cont'd.) <br />Surface Water Monitoring - Bowie No. 1 Mine and West Mine Sites <br />Surface water monitoring at the operator's Bowie No. 1 Mine and West <br />Mines includes quality and quantity measurement for discharges from <br />disturbed lands. Specific parameters are measured in accordance with <br />the operator's NPDES Discharge Permit at four NPDES discharge points <br />upon release of flows from the disturbed areas to a natural water <br />course. <br />The surface runoff from disturbed areas at the portals and support <br />facilities throughout the property is totally contained within the <br />existing sedimentation systems. Surface water is discharged and <br />monitored at sedimentation pond #4 (Outfall 002), the timber storage <br />area sedimentation pond (outfall 003), and the West Mine <br />sedimentation pond (Outfall 006). Refer to the NPDES Appendix in <br />Volume 8A for specific information on the NPDES permit. <br />The storage capacity of the sedimentation ponds at discharge points <br />003 and 006 results in infrequent discharges. Appropriate sampling <br />analyses are conducted in the event discharge occurs. <br />Required NPDES parameters include flow, total iron, total dissolved <br />solids, total suspended solids, and poi. Conditional analysis for oil <br />and grease are also required if a visible sheen is evident on the <br />discharge. Discharge Monitoring Reports (DMA's) are filed quarterly <br />with the Division in accordance with Rule 9.05.13 (2) (a) (iii), and <br />are available for inspection by the Regulatory Authority at the <br />operator mine site office. Any samples which indicate a permit <br />violation will be reported immediately to the Regulatory Authority. <br />Surface water discharge monitoring wi1L continue for such time as is <br />deemed necessary after cessation of use of underground mine workings <br />and after surface disturbed areas have been regraded and stabilized. <br />All equipment for monitoring will be removed when it is no longer <br />required for monitoring. <br />Groundwater Monitoring - Bowie No. 1 Mine and the West Mine Sites <br />The Bowie No. 1 Mine and West Mines are located several hundred feet <br />above the water table of the area. The mines are designed to prevent <br />toxic materials or leachates from contacting water sources. <br />• <br />/~2-) D 8 <br />/1 PP(tO VE~ <br />6/29/o y <br />Revised 12!10/93 <br />Revised 9/21/01 <br />114 <br />
