The Environmental Protection Agency’s (EPA) Clean Water Act of 1972 introduced the National Pollutant Discharge Elimination System (NPDES) which addressed sources of pollution including Municipal Separate Storm Sewer Systems (MS4). Phase II NPDES regulations issued in 1999 regulated Columbus and urbanized areas in Bartholomew County. The Clean Water Act NPDES is an unfunded mandate.
The NPDES permit contains elements called minimum control measures (MCM) that, when implemented, should result in a significant reduction in the discharge of pollutants.
Columbus continues to implement the following MCM’s:
- Public Education and Outreach
- Public Participation and Involvement
- Illicit Discharge Detection & Elimination
- Construction Erosion & Sediment Control
- Post Construction Best Management Practices
- Municipal Operations Pollution Prevention and Good Housekeeping
