Illicit Discharge, Detection and Elimination (IDDE)

Minimum Control Measure #3
Program Objectives Illicit or illegal discharges can lead to pollutants reaching the Cache La Poudre and/or South Platte Rivers. Parameters of special concern include heavy metals, toxics, oil and grease, solvents, nutrients, pathogens, and bacteria. The objectives of the City of Greeley's Illicit Discharge Detection and Elimination (IDDE) Program include the minimization, tracking, controlling, and reporting of illicit discharges into and out of the City's stormwater drainage system, to the maximum extent practicable.

Because there is not a significant industrial presence within the Phase II permit boundary of Greeley, the primary focus of the IDDE program will be on educating the public and local businesses as to how their activities could potentially affect the quality of local receiving waters.
General objectives of the IDDE Program include:
  • Meet the IDDE requirements of the Water Quality Control Division's (WQCD) Stormwater Phase II Program, including quick and effective responses to illicit discharges to the City's stormwater drainage system.
  • Promote proper and consistent illicit discharge detection and elimination methodologies.
  • Promote cooperation regarding IDDE programs among and between all Phase II permittees.
By successfully implementing our IDDE Program, we can:
  • Reduce or eliminate careless or illegal discharges to our stormwater drainage system that can result in pollutants reaching local water bodies like the Poudre and South Platte Rivers or areas of natural importance via stormwater.
  • Reduce or eliminate pollutant discharges that can affect safety and health, water quality, wildlife, and eventually damage the quality of life in the City.
  • Control or eliminate illicit discharges to and from our stormwater drainage system.
