will involve cutting and filling approximately 70,000 cy of material. An <br />as built contour map will be submitted to the Division at the time of a bond <br />reduction request (1"=50, 10'C.I.). <br />The sediment and detention ponds, P-1 through P-9 and the refuse pond, at <br />the mine site will remain in place during the initial phase of final <br />reclamation. Drainage from the regraded areas will be diverted into the <br />three sediment ponds to the maximum extent possible. The collection ditches <br />remaining or being extended for the initial phase of reclamation are shown <br />on Drawings D-4-15 and D-14-16. Small area exemptions are being requested <br />for the No. 1 Mine portal area and the new fan site for the No. 1 Mine. <br />(These areas are shaded on Drawings D-4-15 and 0-4-16). Straw dikes will <br />be installed along the base of these regraded areas until seeding and mulching <br />can be done. The straw mulch in these small area exemptions will be stabilized <br />• <br />by crimping or netting. <br />As part of final reclamation, permanent diversion structures will be installed <br />along the contours shown on Drawing D-4-11. These diversions channels drain <br />runoff from the reclaimed refuse embankment. Drainage from the area above <br />the refuse embankment will continue to flow along the County road, diverted <br />permanently away from the head of the disposal site. <br />0— 4-49a (New 8-14-87) <br />
