Multi-Sector Stormwater General Permit

Activities that take place at industrial facilities, such as material handling and storage, are often exposed to the weather. As runoff from rain or snowmelt comes into contact with these materials, it picks up pollutants and transports them to nearby storm sewer systems, and streams, lakes and rivers. Stormwater pollution is a significant source of water quality problems for West Virginia’s waters. In order to minimize the impact of stormwater discharges from industrial facilities, the WV NPDES program includes an industrial stormwater permitting component. Operators of industrial facilities included in one of the 20 categories of stormwater discharges associated with industrial activity that discharge or have the potential to discharge stormwater to a municipal separate storm sewer system (MS4) or directly to waters of the State require authorization under a WV/NPDES industrial stormwater permit.
