What is MS4GP (EPA Phase II) and how does it affect me?

Municipal Separate Storm Sewer System General Permit (MS4GP) is the Indiana Department of Environmental Management’s (IDEM’s) response to the federal mandate known as the Environmental Protection Agency’s (EPA) Phase II requirements. The EPA's Phase II is the second part of its non-point source pollution regulation under the Clean Water Act.  Phase I included all large metropolitan areas in the United States, and Phase II included many of the more moderate sized urban areas. More information on this program can be found at the MS4 webpages. 

Everyone is affected by these regulations because individual communities, as a response to the regulations, needed to alter their existing ordinances to reduce the amount of non-point source pollution produced within their boundaries. This would lead to increased maintenance costs, new development design standards, and/or new regulations regarding fertilizer use just to name a few.
