CEPSCI Construction Site Best Management Practices

Question 1

A stabilized construction entrance is designed to:

Accepted Answer

Remove mud and debris from vehicle tires to prevent tracking onto public roads

Answer

A stabilized construction entrance made of coarse aggregate scrapes mud and debris from vehicle tires before they exit the site, preventing sediment tracking onto adjacent paved roads and storm drain inlets.

Question 2

What is the recommended aggregate size for a stabilized construction entrance?

Accepted Answer

Coarse aggregate 1.5 to 3 inches in diameter

Answer

Coarse aggregate in the 1.5 to 3 inch range is large enough to knock mud off tires through mechanical agitation as vehicles drive over it, while remaining stable under heavy equipment loads.

Question 3

Inlet protection BMPs are installed at storm drain inlets to:

Accepted Answer

Prevent sediment-laden runoff from entering the storm drain system and being conveyed directly to receiving waters

Answer

Inlet protection devices such as sediment traps, filter bags, or curb inlet protection prevent sediment from entering storm drains and being transported directly to streams or other receiving waters.

Question 4

What is the purpose of a concrete washout area on a construction site?

Accepted Answer

To contain wash water and concrete waste from concrete trucks and equipment, preventing discharge to the stormwater system

Answer

Concrete washout areas contain highly alkaline concrete wash water and residual concrete, preventing it from entering storm drains or waterways where it could cause significant water quality impacts.

Question 5

Which BMP is most effective for controlling erosion on a steep slope that cannot be immediately seeded?

Accepted Answer

Erosion control blanket or turf reinforcement mat installed on the slope surface

Answer

Erosion control blankets or turf reinforcement mats physically protect the soil surface on steep slopes from raindrop impact and runoff erosion, providing interim stabilization until vegetation establishes.
