How should stockpiles be managed to prevent erosion and sediment escape?

• A. Cover or stabilize stockpiles, locate away from drainage, implement perimeter controls around them, and use temporary runoff controls.
• B. Leave stockpiles exposed to wind and rain to allow natural compaction.
• C. Locate stockpiles near drainage and divert runoff into them.
• D. Remove stockpiles immediately after placement.

Answer: (D)

The key idea is to remove the sediment source as quickly as possible to minimize erosion and sediment escape. Stockpiles expose loose soil to rain impact, runoff, and wind, which can detach soil and transport it off-site. By removing stockpiles immediately after placement, you eliminate the opportunity for wind- or water-driven erosion to occur, making sediment control much simpler and more effective. If material must remain on site longer, stabilization or covering and appropriate runoff controls are still important, but the most direct way to prevent erosion is to minimize the exposure time by removing the pile as soon as it’s no longer needed. Leaving piles exposed or located near drainage and trying to divert runoff into them increases erosion risk, so removal addresses the problem at its source.
