Full Breakdown

Under WV Code §22-11 the Department of Environmental Protection issues general and individual NPDES permits for stormwater discharges associated with construction sites disturbing one or more acres, industrial activities, and Municipal Separate Storm Sewer Systems (MS4s). Operators must implement Stormwater Pollution Prevention Plans, install best management practices, and conduct routine inspections. MS4 communities must adopt local programs meeting state minimum measures including illicit discharge detection and post-construction runoff controls. Federal Clean Water Act requirements flow through the state program.

Violations & Penalties

Discharging without a permit or violating SWPPP terms can trigger WVDEP penalties up to $25,000 per day per violation under §22-11-22 and federal enforcement.
