In order to operate an effective Stormwater Pollution Prevention Program (SWPPP), there are six different Minimum Control Measures (MCMs) that must be incorporated into the SWPPP.

  • MCM 1 Public Education and Outreach - Public education outreach materials, public education implementation plan, examples of how to document outreach activities, and examples of outreach materials.
  • MCM 2 Public Participation/Involvement - Examples of how to document events held to give the public a voice in their local SWPPP.
  • MCM 3 Illicit Discharge Detection and Elimination - Regulatory mechanism to prohibit illicit discharges, illicit discharge recognition training, procedures for investigating, locating, and eliminating the source of illicit discharges, and spill response procedures.
  • MCM 4 Construction Site Stormwater Control - Site plan review procedures & items to evaluate, construction site inspection procedures and inspection checklists, and documentation of site plan reviews.
  • MCM 5 Post-Construction Stormwater Management - Legal mechanisms for long-term maintenance of structural stormwater best management practices (BMPs), site plan review checklists.
  • MCM 6 Pollution Prevention/Good Housekeeping - Facilities inventory examples; procedures for determining pond effectiveness of treating total suspended solids (TSS) and total phosphorus (TP); inspection checklists for documenting structural stormwater BMPs, stormwater management ponds, outfalls, stockpiles, and storage and material handling areas; employee training commensurate with the employee's job responsibilities.
