Small Site (AUTOMATIC COVERAGE for 1 Acre or More but Less than 5 Acres)
Full Breakdown
Land-disturbing work of one acre or more in Washington County must run the erosion and sediment controls spelled out in the SWPPP required by DEQ construction permit ARR150000. Typical measures include silt fencing, straw wattles, erosion-control blankets, a stabilized construction entrance, and inlet protection. Disturbed ground must be stabilized promptly, with permanent vegetation or hardscape at completion. Fayetteville and Springdale grading permits require a local erosion plan and site inspections. Given the Illinois River and Beaver Lake watersheds and karst subsurface, sediment reaching a stream or sinkhole is treated as a serious water-quality violation.
Violations & Fines
Missing or failed controls bring stop-work orders and daily fines until corrected. Sediment discharged to a waterway escalates to significant DEQ penalties for each day the violation continues.
