Municipal Separate Storm Sewer System. (MS4). An MS4 is a conveyance or system of conveyances that is: • owned by a state, city, town, village, or other public entity that discharges to waters of the U.S., • designed or used to collect or convey stormwater (e.g., storm drains, pipes, ditches), • not a combined sewer, and • not part of a sewage treatment plant, or publicly owned treatment works (POTW).

Municipal Separate Storm Sewer System. (MS4s). An MS4 is a conveyance or system of conveyances that is: • owned by a state, city, town, village, or other public entity that discharges to waters of the U.S., • designed or used to collect or convey stormwater (e.g., storm drains, pipes, ditches), • not a combined sewer, and • not part of a sewage treatment plant, or publicly owned treatment works (POTW). [Source: EPA]. The communities located with the urbanized area of Xxxxxxx and Xxxxx counties, as defined by EPA, are defined as an MS4s. 6) Stormwater Management Plan (SWMP). EPA’s National Pollutant Discharge System (NPDES) requires small, medium, and large communities to obtain NPDES permits and develop stormwater management programs. The communities located within the Papillion Creek Watershed have developed a Stormwater Management Plan (SWMP) that describes stormwater control practices that will be implemented consistent with permit requirements to minimize the discharge of pollutants from the sewer system. MS4s are required to develop, implement, and enforce a stormwater management program. The SWMP focus is to describe how the MS4 will reduce the discharge of pollutants from its sewer system and addresses these program areas: • Construction Site Runoff Control • Illicit Discharge Detection and Elimination • Pollution Prevention/Good Housekeeping • Post-Construction Runoff Control • Public Education and Outreach • Public Involvement/Participation Program Effectiveness
