NPDES - MS4 Permit
The City of Arden Hills is permitted through the Minnesota Pollution Control Agency (MPCA) to discharge stormwater.  This permit is known as the National Pollution Discharge Elimination System (NPDES) for Municipal Separate Storm Sewer Systems (MS4).  As part of this permit the City of Arden Hills is responsible to put in place Best Management Practices (BMP’s) to control pollution and provide clean storm water discharge to the Maximum Extent Practicable (MEP).  More information on this program is available from the MPCA.

The City updated its permit application in late 2013.
