The MS4 permitting program gives owners or operators of municipal separate storm sewer systems approval to discharge storm water to lakes, rivers and wetlands in Minnesota. The City of Lino Lakes is an MS4. The primary goal of the MS4 general permit is to improve water quality by reducing pollutants in storm water discharges. Specifically the program aims to ensure proper management of storm water discharges into waters of the state. The mandatory requirements for MS4's is written into the National Pollutant Discharge Elimination System (NPDES ) Phase II legislation. In this legislation there are 6 minimum control measures that cities, classified as MS4's, must follow. One of these mandatory requirements is that a city develop, implement and enforce an illicit discharge detection and elimination program. The program must include, through an ordinance or other regulatory mechanism, a prohibition on non - stormwater discharges into the storm sewer system, and include appropriate enforcement procedures and actions. Federal regulations define an illicit discharge as "any discharge to an MS4 that is not composed entirely of storm water ". Illicit discharges are considered "illicit" because MS4's are not designed to accept, process, or discharge such non - stormwater wastes. The Lino Lakes Environmental Board reviewed a draft Illicit Discharge Detection and Elimination (IDDE) ordinance at the June 30th Environmental Board meeting. Suggested ordinance changes were made and reviewed again at the July 28th Environmental Board meeting. The Environmental Board recommended that the IDDE ordinance move on to the City Council.
