V. EXHIBIT E - RECLAMATION PLAN 5.01 Overburden / Topsoil Placement Traditional topsoil is not readily abundant on the subject facility site. The overburden present consists of approximately 5 ft to 10 ft of sand and weathered granite. Overburden will be removed and stockpiled within the mining limits until it is needed in reclamation. It has been determined that slopes above elevation 5800 ft will have the most public visual impact. Therefore, slopes above elevation 5800 ft will be developed by leaving intentional short breaks in the highwalls and leaving diagonal haul roads in place to break up the horizontal lines created during standard highwall and bench mining. This method of reclamation will present a more aesthetically pleasing alternative than backfilling continuous benches. The benches will be backfilled with overburden material at a slope ranging from 1.5:1 (horizontal:vertical) to 1.75:1 (horizontal:vertical) depending on the backfill material and the degree of compaction. Where and when final benches are available for backfill, overburden will be placed on the bench, shaped, and graded. Minor instability in the backfilled slopes should only be surface instability and minor slides will also help to produce a more natural looking slope. In some locations, unavoidable, localized, minor blocks and wedges will likely slide from the highwalls and benches which will serve to further break up the symmetry of mining and create more natural looking reclaimed slopes. As vegetation is redeveloped the surface will become more stable. Slopes below elevation 5800 ft will not be backfilled as they will underwater when the pit becomes used as a water storage reservoir. 5.02 Grading Grading of fill material will be performed on benches at elevation 5800 ft and higher. In general, fill material will be graded to slopes appropriate to the soil type and terrain of the area. Slopes will be graded to minimize erosion and to facilitate revegetation. Backfill at the stated slopes will not completely cover the highwalls, and the upper portions of the highwalls will remain as highwalls. The maximum graded slopes will vary between 1.5:1 and 1.75:1 (horizontal:vertical). Final grading will create a surface that is variable and somewhat irregular to give a more natural appearance while effectively carrying away drainage. 5.03 Revegetation Revegetation details will be provided by Applegate Group, Inc. 5.04 Schedule The schedule of mine development and reclamation will be provided by Applegate Group, Inc. \\Server0l\common\PROJECTS\106052-000 Parkdale Mine Plan\R.
