Pollution Prevention & Good Housekeeping


This control measure covers a lot of ground. From using best management practices for municipal operations such as equipment maintenance, grounds maintenance and snow removal practices, to administering an employee training program on stormwater management and water quality, to implementing retrofit projects to reduce DCIA, and much much more!


Relevant terms

Retrofit: means a project that modifies an existing developed site for the primary purpose of disconnecting DCIA.


Employee Training

Partners for a Clean Environment (PACE) provides free online stormwater training presentations, SOPs, and BMPs related to municipal stormwater operations.

Employee training video for parks maintenance and stormwater protection from Minnesota.

Retrofit program

This impervious cover disconnection spreadsheet created by NEMO decades ago may be useful for DCIA disconnection tracking purposes today.

Municipal operations and maintenance

This BMP guidance from Minnesota Pollution Control Agency provides lots of fact sheets for model programs for maintaining winter road materials, applying fertilizer/chemicals to park and open properties, reducing pet waste, washing vehicles, and many more.

Many towns are already doing good work preventing polluted runoff from their own properties, roads and operations. We’d like to highlight some existing practices towns and institutions are using to meet the many aspects of this control measure and we’ll update this page with examples as we collect them.

Task list

Where the deadline for new MS4 permittees differs from the deadline for exisiting permittees, the second deadline in parenthesis applies to new permittees.
