The best way to prepare for an audit/program review is to read your permit and associated documentation.  All required documentation listed in your permit and SWMP should be readily accessible at all times. 

All program reviews start with a request for basic program information including, but not limited to:

  • The current Stormwater Management Plan (SWMP).
  • The most recent annual reports.
  • MS4 Program organizational chart and associated program responsibilities.
  • Current MS4 map including outfalls and receiving waters.
  • Any formal MS4 implementation agreements with other entities.

The SWMP is a document the MS4 prepares to provide details on how they will implement the MS4 Program requirements in their jurisdiction.  The SWMP is submitted as part of the permit application and is an enforceable part of the permit. 

DEMLR will provide more information about the MS4 audit program soon.
