• 2.05.3 <br />The 2,600 yd' of material removed was used to construct a buttress at the existing refuse pile, as <br />shown in the Reclaimed Configuration & Reclamation Cross Sections of Volume 6A. This <br />represents less than I% of the total fill (266,700 yd'), to be used for backfilling the west portal <br />site. In addition, due to the swell factor, there is more material available for backfilling (266,700 <br />yd') than was removed (230,000 yd'). Therefore, the removal of 2,600 yd' should have no impact <br />on achieving approximate original contour. <br />Part of the above referenced plans for cutslope stabilization at the West Mme portal were <br />completed, but due to another small failure at the site, the repair plan was modified. The current <br />repair required relocation of the existing topsoil stockpile to an azea immediately east of its <br />previous location. The new location of the stockpile is shown in Map 8-7, (OVWM) Facilities. <br />The topsoil stockpile was relocated into a portion of the existing material storage area as shown <br />on the above map. Prior to relocating the topsoil, the collection ditch at the toe of the existing <br />stockpile was filled and the collection ditch rerouted as shown on Map 8-7. <br />A dozer, or other piece of mobile equipment, pushed the topsoil from its present to its new <br />location. Additionally, the available topsoil on which the original stockpile was constructed was <br />removed from the site above the potential failure area. The new topsoil stockpile ties in with the <br />east facing slope upon which the east end of the existing stockpile now rests. The topsoil <br />stockpile was stabilized with the temporary seed mixture presented in section 2.05.4(2)(e)(ii). <br />The existing collection ditch was rerouted as shown on Map 8-7. The ditch was constructed as <br />per the previously approved specification. <br />The cutslope on the north side of the portal azea has experienced minor failures over the past <br />couple of years (1993 t), and it is anticipated that it will continue to do so into the future. The <br />maintenance plan for the area will allow for natural sloughege of the cutslope, and periodic <br />maintenance of the drainage ditches on these slopes. The portal bench at the base of this area will <br />be blocked off so that property damage potential is minimised. Likewise, this will warn <br />employees and other personnel to stay out of this area. <br />Any material that may slide off of the cutslope will be left as is unless it interferes with the <br />operation. If it does interfere with the operation it will be picked up and hauled to the waste rock <br />disposal site unless fill material is needed for minor construction projects at the mine. <br />In the event a slide occurs and a ditch is blocked, the ditch will be reestablished. A dozer will be <br />used to open up the ditch to provide positive drainage from the site. The site will be examined <br />monthly to determine if ditch maintenance will be required. <br />• Upon completion of mining activities, the stockpiled topsoil will be redistributed over the re- <br />graded fill material. The site will then be vegetated as per the plan presented in Section 2.05.4. <br />TR-32 <br />_t3_ <br />9199 <br />Z/ g/oo <br />
