Illicit discharges occur due to illicit connections to the municipal separate storm sewer system (“MS4”) from residential, business, industrial or commercial establishments. As a result of illicit connections, contaminated storm water, wastes or wastewater enters into storm drains or directly into local waters without receiving treatment from a wastewater treatment plant. Illicit connections may be intentional or may be unknown to the property or business owner. Illicit discharges to the city storm water system can cause excessive discharges of pollutants to surface waters and groundwater. These discharges can negatively impact public health, welfare, and the environment by transporting and depositing pollutants. [Code 2006 § 14-1-1.
