Drainage plan <br />Runoff water will be contained in azeas that daylight to natural slopes by maintaining a 3' <br />high by 15' wide berm left in place by mining activity or constructed in those azeas and <br />directed to retention ponds. Runoff occurring during mining operations will flow to the <br />east. Along the eastern edge of the mining azea, a berm will be constructed to channel <br />flows into retention ponds. The ponds will have no outflow, and will be cleaned as <br />needed to maintain their function. The ponds will be located along the eastern edge of <br />the pit. Please refer to the mining plan for pond locations. Also refer to the attached <br />drawing showing pond construction detail. <br />
