Toxics assessment process in Puget Sound

James Maroncelli

Phase 1 of toxic loadings to PS initiated in 2006 by a coalition (PSAT+WA Ecology+…): realized that air deposition was an important pathway

Phase 2: spring 07 $300k from EPA, $300 from Ecology TPA, $55k NOAA funded all programs (because we established a framework for project prioritzation)

  1. Surface runoff
  2. Atmospheric depositino
  3. Permitted wastewater
  4. CSO discharges
  5. exchange with ocean
  6. exchange with contaminated sediments
  7. flux to/from biota


  1. residential areas contributed ~3/4 of loading
  2. permitted contributed <1%

Phase 3: hope to attain funding from national estuary, trying to align with action agenda, but didn’t want to wait in part because Norm Dix wanted to start fixing problems asap.  Year 1 projects focused on analyzing surface runoff, sediments, biota, including $310k from WA legislature on atmospheric deposition (via PSP).  First of these projects will report in June, 2009.

Phase 3, year 2: starting to use action agenda for guidance, PSP wanted an inventory of toxic chemicals by spring 2010 to inform second version of Action Agenda which is due in Sept 2010.  Projects: 3-6 may be funded, proposals due to EPA March 1; Transferring responsibility for toxic loading to PSP science panel.  Joel Baker says funding will be “pragmatic.”  Decision process for potential Oct 2009 funding is to be more formal and rely on recommendations of PSP Science Panel.
