FAQ

An illegal discharge is any discharge to the municipal separate storm sewer system (MS4) that is not rain water, unless exempted by local ordinance. These may occur due to illegal connections to the storm drain system in which wastewater enters the storm drains (e.g. floor drains connected to the storm drain system). Direct dumping or placement of waste so that it can enter the storm drain system is also a form of illegal discharge. Learn more about illegal discharges.
