Illinois Construction
Stormwater Inspections
Illinois's General NPDES Permit ILR10 governs stormwater discharges from construction activities disturbing one or more acres. Administered by the Illinois EPA, the permit was reissued in 2023 with enhanced electronic reporting requirements. Illinois's flat terrain and extensive agricultural drainage networks require careful management of construction stormwater to protect downstream water quality.
