National Summary
Polluted stormwater runoff is commonly transported through municipal separate storm sewer systems (MS4s), from which it is often discharged untreated into local water bodies. To prevent such pollution, many MS4s, which are publicly owned or operated stormwater conveyance systems (including municipally owned storm sewer systems, systems operated by universities, local sewer districts, hospitals, military bases, prisons, etc.), are required to obtain coverage under a stormwater permit.
