Illinois EPA administers federally delegated NPDES stormwater permits requiring uniform construction and municipal stormwater controls that apply on top of any local stormwater ordinances.
Under the Illinois Environmental Protection Act (415 ILCS 5/) and 35 Ill. Adm. Code 309, IEPA issues NPDES permits for stormwater discharges. Construction sites disturbing one or more acres must obtain ILR10 general permits and implement Stormwater Pollution Prevention Plans. MS4 communities require ILR40 permits with six minimum control measures. These federally driven obligations apply universally and cannot be waived by local governments, even where municipalities lack their own stormwater ordinances.
Discharging sediment-laden runoff without an ILR10 permit, failing to implement SWPPP at construction sites, or unpermitted illicit discharges to storm sewers.
