Illinois construction stormwater checkpoint
Illinois EPA describes coverage at one acre or more, including a larger common plan; clearing, grading and excavation are land disturbance.
Officially sourcedFor construction-related clearing, check Illinois EPA when disturbance reaches one acre or is part of a larger common plan; smaller work can still have other requirements.
Questions
- Is the purpose construction or development rather than forestry management?

- What other local, wetland, floodplain or environmental rules apply below the threshold?
- How and when will disturbed soil be stabilized?
