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

Arkansas Erosion and Sediment Control Permit Standards

Heavy RestrictionsApplies statewide across Arkansas (2026)

Arkansas regulates erosion and sediment control statewide through the NPDES construction stormwater program. Sites disturbing one or more acres must implement engineered erosion controls under DEQ oversight. Local jurisdictions may add stricter rules but cannot waive state minimums.

Key Facts

Trigger: 1+ acre disturbed
Stabilization: 70% vegetative cover
Inspection: Weekly plus rain events
Permit: ARR150000 General

Full Breakdown

Erosion and sediment control on Arkansas construction sites is governed by the NPDES Construction General Permit ARR150000 issued under Arkansas Code 8-4-101 and DEQ Regulation 6. Operators must develop and follow a Stormwater Pollution Prevention Plan addressing perimeter sediment controls, stabilized construction entrances, slope protection, and sediment basins. Inspections are required after rainfall events of 0.5 inches or greater and at least every 7 days. Final stabilization requires 70% perennial vegetative cover. The Arkansas Natural Resources Commission supports voluntary conservation but the regulatory floor is the state DEQ permit. Local soil-disturbance ordinances may impose additional requirements.

Violations & Penalties

Inadequate controls trigger DEQ Notice of Violation, mandatory corrective action, civil penalties, and potential stop-work orders. Off-site sediment damage may bring private nuisance claims.

Frequently Asked Questions

Can Arkansas cities require erosion permits below the one-acre threshold?

Yes. Cities may adopt stricter local erosion ordinances applying to smaller sites, but they cannot waive the state NPDES requirements for sites of one acre or more.

What documents must Arkansas construction sites keep on-site?

The signed SWPPP, NOI coverage letter, inspection reports, rainfall logs, and any corrective action records must be available on-site for DEQ inspectors throughout active construction.
