SafetyCâu 573 / 700
A large earthwork site keeps tracking mud onto the public street. Which best management practice (BMP) BEST addresses this under the site's storm water plan?
a.Sweep the mud into the storm drain each evening
b.Wash the street with a hose into the gutter
c.Ignore it because rain will wash it away
d.Install a stabilized construction entrance and clean tracked sediment from the street
Giải thích
A stabilized construction entrance of crushed rock knocks mud off tires before vehicles reach pavement, and any tracked sediment should be swept up and disposed of properly, not washed into drains. Options a and b send sediment straight into the storm drain system, a violation. Option c allows pollution to reach waterways. Preventing and cleaning track-out protects water quality and keeps the site compliant.
