Secondary PermitteesOur municipal stormwater permits generally cover cities and counties. However, there are other public entities (such as ports, prison complexes, parks and recreation districts, universities, or diking and drainage districts) that own or operate a stormwater sewer system located in a Phase I or Phase II city or county.
These stormwater sewer systems are also known as municipal separate storm sewer systems (MS4). A public entity with an MS4 may be required to get a secondary municipal stormwater permit.
