Urbanized areas are more likely to have activities that contribute pollutants to stormwater runoff, like applying anti/deicing mixtures to roads; fueling vehicles; grease, oil, and other spills; landscaping; and using pesticides and fertilizers. Urbanized areas have a large amount of impervious surfaces, or surfaces that rain and snowmelt cannot pass through, such as streets, driveways, rooftops, parking lots and sidewalks. Stormwater runoff from these surfaces travels faster and in higher amounts, damaging rivers, streams, and wetlands; destroying aquatic habitats; increasing the amount of pollutants that enter surface waters; and limiting groundwater recharge and the MS4 program is to help mitigate the impact. | ||

+ | 1 An MS4 located fully or partially within an urbanized area as determined by the latest Decennial Census and owned or operated by a publicly owned entity that has the potential resident capacity, bed count occupancy, or average daily user population of 1,000 or more.

+ | |||
+ | 2 An MS4 owned or operated by a municipality with a population of 10,000 or more. | ||
+ | |||
+ | 3 An MS4 owned or operated by a municipality with a population of at least 5,000 and discharges or has the potential to discharge stormwater to one of the following: | ||
+ | 4 A water identified as an outstanding resource value water as identified in Minn R. 7050.0180, subparts 3 and 6. | ||
+ | 5 A water identified as a trout lake or trout stream as identified in Minn. R. 6264.0050, subparts 2 and 4. | ||

+ | |||
+ | Owners or operators of MS4s that meet the above criteria must submit an MS4 General Permit to the MPCA. Under the permit, the owner or operator is required to reduce the amount of sediment and pollution carried from stormwater to surface and ground water to the maximum extent practicable. Additionally, the permit requires the system owner or operator to develop a stormwater pollution prevention program (SWPPP) that incorporates best management practices (BMPs) most appropriate to their MS4. | ||
