• Each layer will be controlled for stormwater construction flows with the use of construction <br />fabric/fencing and waddles where needed. Removal would occur during the dry season (Fall). <br />• Access roads for the heavy equipment will be cut into the waste rock, but will be very temporary <br />in nature. <br />• Waste rock will be placed along the cut portal face in a series of layers, with each layer being <br />compacted into place with the use of heavy equipment. <br />• The Deadman Gulch containment features will be maintained until the native channel is exposed. <br />Removal of the inlet catchment basin, pipe and outlet features will be the final portions removed <br />once all waste rock is eliminated. <br />• The waste rock will be blended into the contours of the slope. A 1 ft cap of inert alluvium <br />gathered from the Level 3 area will be placed on top of the waste rock. This cap will be <br />compacted down to a total depth of 1 foot with the use of heavy equipment. Top soil retained <br />along the perimeter of the pad, and as part of the road berm will be smoothed over the alluvium <br />surface. <br />• The entire face of the waste rock storage area will be re-seeded using the appropriate BLM <br />approved seed mix (refer to Table B.1). The seed will be applied in Spring and Fall seasons until <br />adequate re-vegetation is achieved. <br />• Storm water channels (both run-on and run-off) will be constructed to minimize the <br />potential for storm water contact with the encapsulated waste rock. A run-on channel will <br />traverse the upper edge of the waste rock repository, while a run-off channel will be <br />constructed at the toe. The run-off channel will be designed to control water energy with <br />the use of large cobble to boulder-sized materials. The purpose of this feature is to <br />control water energy and allow for sediment fall-out. <br />• Revegetation and stormwater conditions will be monitored to ensure compliance and <br />successful revegetation endpoints. <br />The resulting waste rock repository will blend with the surrounding topographic contours. The <br />waste rock will be retained within an encapusulated cell comprised of top soil and non-reactive <br />alluvium. The underlying alluvium, the waste rock, and the alluvium cap will be compacted. <br />This will assist with `shedding' of any storm water. In addition, the run-on channel will intercept <br />any storm water that may be traveling down-slope towards the waste rock storage. The runoff <br />channel will capture any sheet flow coming off the waste rock storage. These channels will have <br />large unconsolidated non-reactive materials to attenuate and dissipate flow energy and decrease <br />10
