Stormwater Action Monitoring — source identification

SAM's source control studies are focused on learning which actions by permittees and businesses in Western Washington are key to preventing illicit discharges. We are also gaining a better understanding of how to detect sources of pollution to stormwater. 

We are looking for new projects for this permit cycle see our process for new projects below. 

What are we learning?

Stormwater Action Monitoring (SAM) contracted three source identification (ID) projects during the 2013-2019 permit term. SAM source ID projects can occur at site or regional scales and the results can be used across jurisdictions.

Source ID Trainings

As part of a SAM project to update the 2013 Illicit Connection and Illicit Discharge (IC/ID) Field Screening and Source Tracing Manual, municipal government staff will have eight opportunities to attend training on updated IDDE field methods in late 2019 - early 2020. Tentative locations: Bellingham, Everett, Poulsbo, Snoqualmie, Redmond, Renton, Olympia, and Vancouver (subject to change until flyer completed).

Completed SAM source identification studies

SAM source identification projects

The following projects are now underway. The third project is approved by SWG and needs a study lead. 

What is the process for new projects?

The Stormwater Work Group (SWG) is wrapping up a year-long stakeholder process to select the SAM study topics for the next permit term. The SWG's caucuses and technical subgroups met to discuss and further narrow the list of topics developed at the February 2019 SAM priorities workshop. The SWG will recommend a final list of study topics at their June 5, 2019 meeting. A third solicitation process will begin in fall 2019 using topics recommended by the SWG in June 2019. New projects might begin as soon as fall 2020.
