What is the storage requirement for a temporary sediment basin as per EPA guidelines?

The correct answer reflects the guidelines set by the Environmental Protection Agency (EPA) regarding the storage volume required for temporary sediment basins in construction sites. According to the guidelines, a temporary sediment basin should provide a minimum storage requirement of 3,600 cubic feet per acre of disturbed area. This volume is crucial because it helps to effectively capture and retain sediment, allowing for adequate settling before the water is discharged from the site, thereby preventing sediment pollution in nearby water bodies.

This storage capacity is based on the need to manage stormwater runoff and to mitigate the impacts of erosion and sedimentation during construction activities. By ensuring that 3,600 cubic feet of storage is available per acre, a temporary sediment basin can adequately reduce the amount of sediment carried off-site, protecting both land and water resources.

Other options do not meet the recommended capacity outlined by the EPA for effective sediment control in temporary basins, which is why they do not align with the established standards.
