Kansas Erosion Control Law: Statewide Environmental Rules Rules (2026)

Key Facts

Trigger: 1+ acre disturbance
Required plan: SWPPP on site
Inspections: Every 7 days minimum
Authority: KDHE NPDES program

Full Breakdown

KDHE's stormwater construction general permit, issued under K.S.A. 65-165, applies uniformly across Kansas. Operators must develop and implement a Stormwater Pollution Prevention Plan identifying potential pollutants, sediment and erosion controls such as silt fence, inlet protection, stabilized construction entrances, and post-construction stabilization. Inspections are required at minimum every seven days and after qualifying rain events. Records must be kept on site. Local ordinances may add stricter requirements and inspection regimes but cannot remove KDHE BMP obligations or the SWPPP duty.

Violations & Penalties

Sediment discharges or missing SWPPPs draw KDHE notices of violation, stop-work orders, and civil penalties; repeat violators face escalating fines under K.S.A. 65-170d.

A Stormwater Pollution Prevention Plan documents site-specific erosion and sediment controls, inspections, and corrective actions required by KDHE during construction.
