A storm inlet lacks protection while disturbed soil drains toward it. What is the correction?
Correct Answer
C) Install inlet protection before sediment reaches the storm sewer
Install suitable inlet protection promptly and maintain upstream erosion controls. Choose a system compatible with drainage and overflow needs; blocking the inlet indiscriminately can create flooding. EPA describes inlet protection as a secondary control, ideally installed before disturbance. Source: https://www.epa.gov/system/files/documents/2021-11/bmp-storm-drain-inlet-protection.pdf
