water discharged directly from the mine in ten (10) years. During the second quarter of <br />1995, wet spring weather caused the mine to fill and begin discharging iron laden water. <br />In order to treat this iron laden water, a 4" diameter pipe was installed to convey the <br />discharge from the No. 3 mine to the long pond. The discharges from the mines were <br />combined effective August 11, 1995. <br />The water treatment ponds (long pond, T-1, T-2, and P-9) at the No. 1 Mine Site are <br />considered permanent and support the developed water resources postmining land use. <br />Additionally, the portal area, 36-inch culvert, 6-inch pipe, bridge, and pipeline corridor are <br />considered permanent to support the developed water resources postmining land use. <br />Ponds <br />Based on a vegetation survey performed during July 1992, a demonstration was made that <br />untreated drainage from the reclaimed mine site does not contribute additional suspended <br />solids above natural conditions. Therefore, sedimentation control is no longer required at <br />• the No. 1 or No. 3 Mine Sites. See the discussion beginning on page 4-19 for more details. <br />Pond P-1 was a depression to dissipate energy in front of a culvert located between the <br />No. 1 Mine and the No. 3 Mine. The pond was backfilled and reclaimed late in 1994. <br />Pond P-2 was a sediment pond for the water tank area. It was backfilled and reclaimed <br />late in 1994. Pond P-3 was the sediment pond for the No. 3 Mine. The embankment on <br />this pond was breached in 1994. Pond P-4 is the depression to dissipate energy in front <br />of the culvert located north of the entrance to the No. 1 Mine. No reclamation is required <br />for this pond since it is not actually a pond because it was revised when the mine was <br />reclaimed in 1987. Ponds P-5, P-6, P-7 and P-8 were energy dissipater ponds. They <br />were all reclaimed in 1994. <br />• <br />4-ii (Rev. 5/01) <br />
