West Virginia Erosion Control (2026)

Key Facts

Trigger: 1 acre disturbed
Required plan: SWPPP with BMPs
Mining rules: WV Code §22-3
Inspection cadence: Weekly plus rain events
Enforcement: WV DEP

Full Breakdown

Construction operators disturbing one or more acres must obtain coverage under the WV/NPDES Construction Stormwater General Permit and prepare a Stormwater Pollution Prevention Plan addressing erosion controls, sediment basins, stabilized entrances, and inspection schedules. Surface mining and oil-and-gas operations follow separate but parallel sediment-control rules under §22-3 and §22-6A. The DEP Division of Water and Waste Management enforces statewide standards, and MS4 municipalities must adopt local ordinances at least as stringent as the state benchmark, ensuring uniform protection of streams from sediment pollution.

Violations & Penalties

Failure to install required BMPs or maintain SWPPP records can result in stop-work orders, fines up to $25,000 per day, and required corrective action.

Frequently Asked Questions

What erosion controls are required on small homesites?

Sites under one acre fall outside NPDES coverage, but local sediment-control ordinances and the WV nuisance law against muddy runoff onto neighbors and roads still apply.

Do farms have to follow erosion-control rules?

Routine agricultural operations are exempt from NPDES construction permits, though confined animal feeding operations and conservation plans may impose separate state requirements.
