<br />EXHIBIT E <br />RECLAMATION PLAN <br />The reclamation plan for the Timnath Connell site is a lined water storage reservoir. It will be <br />constructed in the same sequence that has been successfully employed by Connell at the <br />Wellington Downs Site permit located immediately to the west. <br />Phasin¢ <br />Reclamation will be concurrent with mining and therefore will be completed in phases. The first <br />phase of reclamation will occur on the north end. As Connell mines the north side of the <br />property, they will begin backfilling areas not included as part of the final reservoir such as the <br />wash plant site and the stockpile areas. The outer perimeter of this area will be lined and sealed <br />to form a portion of the reservoir. As mentioned eazlier, stationary equipment will be placed on <br />the north side for the extent of the project. Therefore, only the areas on the west side of the <br />property that are not expected to be disturbed for the remainder of [he mining will be reseeded. <br />The second phase of reclamation will involve sealing and backfilling the perimeter of the <br />reservoir On-site overburden and the claystone bedrock will be used to seal the perimeter of the <br />reservoir to isolate the site from the valley fill aquifer. As the reservoir shoreline are backfilled <br />with overburden and claystone these areas will be compacted to create a liner. <br />Scrapers will be used to place overburden and claystone material along the property perimeter. <br />Wheel compaction by scrapers will primarily be used to acquire the 95% compaction <br />specification. Quality control will be used during ]fining operations to determine that compaction <br />is being achieved. This will include an evaluation and possible changes in the water <br />applications, lift thickness, and compaction method (wheel rolling, sheep's foot compactor, etc.) <br />During initial stages of the liner construction, several in-place tests will be done to deternine if <br />the compaction method is sufficient to meet the 95% standard proctor design. Thereafter <br />Connell will be conducting regular on-going compaction testing. <br />In the final phase Connell will mine [he interior of the reservoir. As strips of the property are <br />mined, Connell will closely follow with backfilling of overburden, capping with topsoil, and <br />vegetating to minimize the amount disturbance at any one time. Once [he backfilling is <br />completed the perimeter reservoir shoreline material will be graded to a 3H:1 V slope. <br />Connell plans to mine to the claystone bedrock. The claystone is generally competent and will <br />withstand erosional forces. However, some areas might not contain marketable sand and grave! <br />down to the bedrock. This area will remain exposed until the reservoir is filled with water. To <br />help suppress dust, Connell will consider seeding areas of the reservoir bottom that have a high <br />potential for dust emission. <br />
