MINING PLAN <br />Topsoil Removal and Stockpiling: <br />REQUIREMENT: Topsoil removal will occur to the depth indicated in the pre- <br />mining assessment described above. In the event pockets of soil are encountered that are thinner or <br />thicker than the indicated depth, adjustments in the salvage depth will be made. Topsoil stockpiling <br />will occur at appropriate locations on land adjacent to the anticipated mining area. <br />REQUIREMENT: Topsoil stockpiling will occur on land adjacent to the <br />anticipated mining area. These stockpiles will be located where erosion of the piles will not result in <br />excessive sedimentation into adjacent drainageways. The stockpiles should be located where a need to <br />relocate the stockpile is minimized and where replacement of the soil on backfilled land is <br />comparatively easy. <br />Discussion: Topsoil stockpile placement cannot always meet these requirements in a <br />strict sense simply because the lay of the land or indefinite sand deposit characteristics prevent this <br />from occurring. However, preventing excessive sediment discharge into drainageways will always be <br />observed, even if that means locating a stockpile further from the mining area than would be ideally <br />desirable. Rounded mound stockpiles tend to be the easiest to manage and look better, although they <br />can be difficult to produce. <br />REQUIREMENT: Topsoil stockpiles will be sloped and prepared for protective <br />seeding. The side slopes will not be steeper than 2:1. <br />Exception - If the stockpiled soil is expected to be replaced prior to stockpile <br />protection being effective, protective measures are not necessary. However, in the event that expected <br />replacement does not occur in the time frame initially anticipated, appropriate protective measures <br />will be taken. <br />Some Examples: <br />1.) Soil stripped between September and March and expected to be replaced by June of <br />the following year, need not be protected. <br />2.) Soil stripped between September and March and expected to be replaced later than <br />June of the following year, must be protected. <br />3.) Soil stripped between September and March and expected to be replaced in June, <br />but in April or May it is found that it will not be replaced until later than July, must be protected as <br />soon as it is determined that it will not be replaced as originally anticipated. <br />Coal Creek Sand Resource Amendment 3 (2005) - M-1988-044 Exhibit D Page 26 <br />
