Municipal operations have the potential to impact stormwater. Preventing stormwater pollution from municipal operations not only protects stormwater, but also sets a good example of how stormwater is managed in your jurisdiction to those who live, work, and visit your community.

The MS4 General Permit requires permittees to maintain an inventory of municipally owned facilities that may pollute stormwater (MS4 General Permit Part III.D.6.a.). Examples of such facilities include:

  • composting,
  • equipment storage and maintenance facilities,
  • hazardous waste disposal facilities,
  • hazardous or solid waste handling and transfer facilities;
  • landfills,
  • parks,
  • pesticide storage areas,
  • public parking lots,
  • public golf courses;
  • public swimming pools,
  • public works yards,
  • recycling facilities,
  • salt storage areas,
  • vehicle storage and maintenance (e.g., fueling and washing) yards, and
  • materials storage yards.

In addition, the permittee must implement best management practices (BMPs) to reduce the impacts of these facilities to surface water (MS4 General Permit Part III.D.6.b.).
