removed than what will be necessary for immediate redistribution. Any <br />• additional stockpiles may be placed on flat spoil backfill areas or <br />stable portions of the permit area where stockpiles will be protected <br />from external effects of both wind and water erosion. Stockpiles have <br />also been placed to avoid disturbances other than those incidental to <br />their deposition and removal. <br />Colowyo utilizes a variety of methods to protect topsoil stockpiles from <br />erosion. Colowyo will utilize one or more of the following techniques to <br />protect topsoil from erosion. Small catchment berms and ditches may be <br />employed to route surface runoff away from stockpile areas. Small sumps <br />or dozer basins may be employed to collect runoff. Adjacent disturbance <br />areas may be ripped or otherwise roughened to reduce runoff. Topsoil <br />stockpiles may be strategically placed and constructed to allow runoff to <br />be routed around stockpile locations rather than pond against a <br />stockpile. <br />Topsoil marker signs will be placed on each stockpile to prevent <br />inadvertent disturbance, unnecessary compaction or contamination. <br />At the locations where topsoil piles are located on undisturbed land, in <br />place topsoil and vegetation will not be removed prior to stockpiling <br />topsoil. <br /> <br />4 .0 6- 2 a Reyisioo s~,yn;mea ~- i 3• o i <br />Revision No. T ~ - s j <br />
