What is required of an illicit discharge detection and elimination program?

Recognizing the adverse effects illicit discharges can have on receiving waters, the Phase 2 rule requires an operator of a regulated small MS4 to develop, implement, and enforce an illicit discharge detection and elimination program. This program must include the following:

  • A storm sewer system map, showing the location of all outfalls and the names and location of all waters of the United States that receive discharges from those outfalls.
  • Through an ordinance, or other regulatory mechanism, a prohibition (to the extent allowable under State, Tribal, or local law) on non-stormwater discharges into the MS4, and appropriate enforcement procedures and actions.
  • A plan to detect and address non-stormwater discharges, including illegal dumping, into the MS4.
  • The education of public employees, businesses, and the general public about the hazards associated with illegal discharges and improper disposal of waste.
  • The determination of appropriate best management practices (BMPs) and measurable goals for this minimum control measure.
