mixture. Work in Area "B" will need to be completed before this storage area can be <br />abandoned and reclaimed. <br />Access Haul Road ("D") <br />Reclamation of this road will be the second-to-last item scheduled. With the <br />exception of Area "A", the road is needed for access to all the sub-areas. The road will be <br />reclaimed with procedures similar to those used in the past. A track excavator will start at <br />the top of the road -pulling the toe of the road back up to the road surface. This material <br />will then be sloped and blended into the road escarpment -leaving erosion control bars in <br />place. Experience with this procedure has shown that a sufficient amount of gypsiferous <br />soil can be blended into the top of the slope -leaving enough growth medium base for <br />vegetation. As the final procedure, seed will be hand broadcasted on the newly <br />constructed slope immediately above the excavator and continue as the excavator works <br />itself down the road. Scheduling here may or may not accommodate late-fall seeding but <br />vegetation results will be monitored. <br />Previous Uaner Mining Area ("E") <br />This sub-area is the northern-most location of previous mining operations. When <br />mining was concluded here, an escarpment of approximately 100 feet was left in place. <br />Mitigation has been in progress for several years with on-going reclamation efforts. <br />The reclamation has been approached by back filling and sloping against the escarpment. <br />A series of slopes and mounds (stabilized, top-soiled and vegetated) have been developed <br />with the process proceeding down slope. Standard and successful erosion control <br />methods developed through the years are incorporated into this site. During periodic site <br />visitations, BLM and DMG representatives have concurred that on-going reclamation in <br />this area is successful. <br />Fill material used in re-sloping consists of reject gypsum wallboazd material. <br />Reclamation has proceeded in accordance with a Notice of Backfill Activity described in <br />the Colorado Land Reclamation Act for the Extraction of Construction Material. This act <br />is administered by the Colorado Division of Minerals and Geology. <br />The material has proved to compact well and has produced stable slopes similar to <br />slopes constructed elsewhere with clastic material. The sloping procedure consists of <br />placing the wallboard material in small lifts and compacting the lifts with a track dozer. <br />Additional compacted lifts of clastic material are then added as capping. Topsoil <br />applications and seeding methods are similaz to other areas where reclamation has been <br />successful. <br />Another reclamation technique used on these slopes is the addition of mulching <br />material consisting of trees and brush. This mulch is cleared and stockpiled along with <br />topsoil prior to mining activity. Mulch placement provides soil stabilization, reduces <br />4 <br />
