MINING PLAN <br />2. In the case where the mining area is large enough that implementing the concept in <br />item 1 above will not work, the mining process will be implemented in such a fashion <br />that backfill material stockpiled on top of mineable sand will only have to be moved <br />once to do the backfilling. <br />3. As a rule, freshly removed soil and overburden will not be stockpiled on top of <br />replaced soil and overburden. Instead, when an area is backfilled it will be seeded at <br />the next planting period. <br />4. In most cases, this process of stockpiling works best if the soil and overburden is <br />stockpiled adjacent to the mining area AND parallel to the direction of mining. <br />Stockpiling ahead of the operation (in an area that will be mined next) can be done, but <br />greatly increases the cost of backfilling due to increased haulage costs. Stockpiling <br />behind the mining operation should only occur with an initial cut into a new mining <br />area. <br />The object of this pre-planning of the stockpiling locations is to create a situation <br />where the overburden can simply be pushed back into the mined out pit and then the <br />soil spread over the top of the backfilled area. In this way, backfilling is least <br />expensive and reclamation can be implemented more promptly. <br />6. It is also important to keep access corridors to the mining operation in locations that do <br />not block the ability to reclaim mined out areas. That is, temporary access roads should <br />not be arranged so they go through areas that are being reclaimed. Ideally, access roads <br />should follow routes that go around the perimeter of lands being reclaimed so the <br />reclamation of a relatively large area is not divided into smaller units. When a <br />reclamation parcel is broken into a patchwork of smaller pieces by various roads or <br />other mining activities, those areas reclaimed later often remain visibly different from <br />the older reclamation for decades. Eventually the appearance of the reclaimed areas <br />will merge, but that can take a very long time. Although keeping access corridors away <br />from reclamation is not required, whenever possible, it should be implemented in the <br />interest of efficient reclamation. It will be recognized that such a separation is not <br />always feasible or necessarily efficient in all cases. When separation is not possible it <br />should always be for a good reason. <br />Coal Creek Sand Resource Amendment 3 (2005) - M-1988-044 Exhibit D Page 42 <br />
