IC/ID Field Screening Guidance Manual and Training

Herrera, the Washington Stormwater Center, and King County received a Grant of Regional or Statewide Significance from the Washington State Department of Ecology to develop a guidance manual for field screening and tracing the sources of illicit connections and illicit discharges (IC/ID). The manual provides a single, detailed source of information intended for use by municipal staff throughout Washington. In developing the manual, Herrera surveyed Washington municipalities with stormwater permits about their current methodologies, reviewed available literature, and facilitated discussions with ROADMAP and the Eastern Washington Stormwater Coordinators Group. We also developed training materials and provided three trainings in Wenatchee, Everett, and Puyallup to a total of 135 attendees from about 60 local agencies. The IC/ID manual and training videos are available on the Washington Stormwater Center website: www.wastormwatercenter.org/illicit-connection-illicit-discharge.
