Stormwater Action Monitoring - Administering pooled resources

We administer the Stormwater Action Monitoring (SAM) program, and the Stormwater Work Group (SWG) has oversight.

As the service provider for SAM, we aim to provide credible and transparent accountability for expenditures of permittee funds to implement SAM with oversight by the PRO-C. In our role as the SAM service provider, we:

  • Track revenue and expenditures.
  • Report cash flows quarterly.
  • Contract for SAM projects.
  • Maintain transparency via websites.
  • Attend SWG and PRO-C meetings.
  • Run deliverable-based agreements for SAM projects.
Approved deliverables are authorized for payment. All SAM pooled resources from municipal stormwater permittees are held in private/local accounts. Only authorized expenditures can pull from these accounts.

Pooled resources oversight committee (PRO-C)

The PRO-C is a formal subgroup of the SWG, PRO-C Charter, that provides oversight on SAM projects' scopes, schedules, budgets, and SAM contracting decisions. The PRO-C is comprised of local government representatives (permittees) and other stakeholders (non-permittees such as state or federal government). They have regular meetings to provide transparency and accountability in spending the funds contributed by municipal stormwater permittees in Western Washington. The PRO-C meets as needed, generally four to five times per year and is organized by the SAM coordinator. The PRO-C and Ecology used a report card approach to evaluate each other's performance on SAM implementation twice during the 2013-2019 permit term: 2016 SAM Implementation Report Card and 2019 SAM Implmentation Report Card.

SAM funding

Who is included in the cost sharing program?

In 2013, permittees notified their permit managers in writing which S8.B and S8.C permit condition option they chose. The vast majority of permittees opted to pool monitoring moneys to launch this new program, SAM. (At the time the program was called RSMP — regional stormwater monitoring program).

Other resources are also contributed to the program:

  • USGS — $20,000 analyzed nearshore sediment samples for microplastics
  • Washington Department of Fish & Wildlife — analyzed mussel tissue samples for microplastics and contaminants of emerging concern
  • Ecology — donates lead staff, meeting expenses, and technical services to ensure SAM's overall success
  • USGS — $60,000 of co-op funds to conduct enhanced flow data recording using pressure transducers at 15 small streams sites
  • USGS — $50,000 of co-op funds to conduct comparisons between small stream data and National Water-Quality Assessment (NAWQA) data in the Puget Sound region in 2015
  • Washington State Department of Agriculture — $53,000 analyzed 75 stream sediment samples for an additional 100 pesticides, and a report
  • Penn Cove Shellfish — donated mussels for both rounds of mussel monitoring study in urban nearshore environments
  • City of Redmond — donates project management task on the Paired Basin Watershed study
