Illicit Discharge Detection and Elimination in Storm Drains Manual - Part 1

Mark P. Rossow, PhD, PE Retired


Course Outline

This five-hour online course incorporates the experience of more than 20 Phase I communities that were surveyed about their practices, levels of program effort, and lessons learned. These communities took many different approaches to solve the IDDE problem, provided great insights on common obstacles, and set realistic expectations.  The course summarizes this information to help 1) Define important terminology and understand key illicit discharge concepts; 2) Conduct an audit to understand community needs and capabilities; 3) Establish adequate legal authority; 4) Develop a tracking system to map outfalls and document reported illicit discharges; 5) Conduct desktop analyses to prioritize targets for illicit discharge control; 6) Conduct rapid reconnaissance of the stream corridor to find problem outfalls; 7) Apply new analytical and field methods to find and fix illicit discharges; 8) Educate municipal employees and the public to prevent discharges; and 10) Estimate costs to run a program and conduct specific investigations

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

This course teaches the following specific knowledge and skills:

Intended Audience

This course is intended primarily for civil, environmental, and hydraulic engineers concerned with storm water management.

Benefit to Attendees

A person completing this course will be familiar with and able to apply procedures for planning and implementing an IDDE program.

Course Introduction

Studies have shown that dry weather flows from the storm drain system may contribute a larger annual discharge mass for some pollutants than wet weather storm water flows.  Detecting and eliminating these illicit discharges involves complex detective work, which makes it hard to establish a rigid prescription to “hunt down” and correct all illicit connections.  Frequently, there is no single approach to take, but rather a variety of ways to get from detection to elimination.

Course Content

This course is based on Chapters 1-10 of the U.S. Environmental Protection Agency document, “Illicit Discharge Detection and Elimination, A Guidance Manual for Program Development and Technical Assessments” by E. Brown, D. Caraco, and R. Pitt, October, 2004.  The Technical Appendices from the manual are included as reference material.

Course Summary

Designed with a broad audience in mind, including agency heads, program managers, field technicians and water quality analysts, this course provides Phase II communities with guidance for the development and implementation of their own programs. The course addresses the broad range of administrative and technical considerations involved with setting up an effective IDDE program.
