Illicit Discharge Detection and Elimination

The Center for Watershed Protection has been working with Dr. Robert Pitt of the University of Alabama to research the most cost effective and efficient discharge detection techniques currently in use around the country, and synthesize these findings into specific guidelines on illicit discharge identification and removal. This project was made possible through funding from an EPA cooperative agreement.

The final product of this project is the Illicit Discharge Detection and Elimination Guidance Manual, a comprehensive manual that outlines practical, low cost, and effective techniques to for program managers and practitioners to use. The guidelines include details on the types of testing used to detect illicit discharges, information on estimating program costs in terms of capital and personnel expenses, and timelines that estimate how long program implementation will take.

The Illicit Discharge Detection and Elimination Guidance Manual provides
valuable guidance for Phase II NPDES MS4 communities and others seeking to establish Illicit Discharge Detection and Elimination (IDDE) programs and investigate non-storm water entries into storm drainage systems. The manual also has application for Phase I communities looking to modify existing programs, and for groups interested in conducting public outreach and awareness activities as part of watershed restoration projects.
