Which practice best describes the purpose of perimeter controls around stockpiles?

• A. To capture or redirect runoff around stockpiles to prevent erosion and sediment escape.
• B. To prevent all runoff from reaching the site.
• C. To enhance aesthetic appearance around stockpiles.
• D. To allow unrestricted access around piles.

Answer: (C)

Perimeter controls around stockpiles are meant to keep sediment on site by managing the stormwater that runs off exposed piles. When rain hits a stockpile, surface runoff can pick up fine soil and carry it away, leading to erosion and sediment leaving the site. Perimeter controls create barriers or channels that slow and direct that runoff so sediment can settle out before the water leaves the area. This protects water quality, reduces downstream erosion, and helps keep the site stable. Focusing on aesthetics or trying to prevent all runoff aren’t the real purpose here. Aesthetic improvements aren’t a primary goal of these controls, and while you can mitigate runoff, you typically can’t stop it entirely; the goal is to minimize sediment transport and keep it from leaving the site.
