Stormwater Management Program Plan

The Village of River Grove is an operator of a Municipal Separate Storm Sewer System (known as MS4), per the Illinois Environmental Protection Agency’s (IEPA) National Pollution Discharge Elimination System (NPDES) Phase II Program.

The ILR40 NPDES Permit for MS4 communities requires that the Village of River Grove develop, implement, and enforce a Stormwater Management Program Plan (SMPP) designed to reduce the discharge of pollutants into neighboring waterways to the maximum extent practicable, to protect water quality, and to satisfy the water quality requirements as intended by the Clean Water Act (as amended in 1987).
