Exhibit E Skull Creek Sand Project <br /> Phase 2 - Soils Handling <br /> As shown in Exhibit D, prior to mining all recoverable soils within the affected area will first be <br /> salvaged (between 2"-6") and stored in windrow stockpiles surrounding the various operational <br /> areas as depicted on Map D-3. These stockpiles will be bermed and seeded with the interim <br /> seed mix detailed below in Table 3 to establish interim plant growth and to avoid soil loss by <br /> erosion. Soil salvage volumes are estimated at a depth of approximately 6 inches as depicted on <br /> Map D-3, but actual salvage volumes will vary dependent on site conditions. The final salvage <br /> volumes will be surveyed and reported to the division and will also be used to estimate the final <br /> cover depth for reclamation. <br /> As mining of the open pits progresses and concurrent backfill and regrading is completed, soil <br /> from the windrow stockpiles will be placed over the top of backfill at a depth determined by the <br /> final salvage survey. <br /> Phase 2 - Mulching and Seeding <br /> Once the soil has been placed, the soil will be mulched, strawed and seeded. Mulch and straw <br /> will both be applied at a rate of 1.5 tons per acre in the re-soiled areas. Seed will be applied <br /> using a drill seeder with 3 different mixes being utilized. Table 1 shows the mix that will be used <br /> for the reclaimed open pit areas. Table 2 is the mix that will be used in the areas where the <br /> Product and SPRS stockpiles are located as well as the roads and surface disturbance areas <br /> surrounding them. Table 3 shows the interim seed mix that will be used for soil stockpiles <br /> during mining to stabilize the piles. Timing for application of seed will preferentially occur <br /> during the months of October, November and possibly December depending on weather <br /> conditions and prior to significant snowfall. This timing has been proven to maximize the <br /> establishment of reclaim vegetation. <br /> Table 1: Revegetation Seed Mixture for the Pit Lands at the Skull <br /> Creek Sand Project <br /> Rate* <br /> (## Seeds/ft2 <br /> PLS/Ac) <br /> SHRUBS <br /> Artemisia tridentate subsp.
