Ecology hires a contractor to support the Green-Duwamish Pollutant Loading Assessment
Ecology secured a contract with RESPEC to provide technical support for the HSPF (Hydrological Simulation Program – FORTRAN) Watershed Model. RESPEC will help set up the Pollutant Loading Assessment (PLA) model so it better addresses the management scenarios. In addition, the RESPEC contract will provide technical support for the Soos Creek Total Maximum Daily Load study, led by our Environmental Assessment Program.
The PLA Technical Advisory Committee met on February 19, 2020 to discuss important project updates. Meeting minutes will be posted on the project document page when available.

Green-Duwamish Pollutant Loading Assessment update
The Green-Duwamish Pollutant Loading Assessment (PLA) is an ongoing modeling project aimed at identifying sources of pollution in the Green-Duwamish watershed and strategies to reduce those sources. As of January 2020, our PLA Team is currently preparing the preliminary calibration results from the watershed model.
Agreed Order finalized for Emerald Gateway Site
Ecology finalized the Agreed Order for the Emerald Gateway Site on January 15, 2020. The order requires the Potentially Liable Party to investigate environmental conditions, develop a cleanup plan, and conduct an interim (partial) cleanup. The interim action will remove soil from a portion of the site to allow for redevelopment of the property.
We held a public comment period for the draft Agreed Order and draft Interim Action Workplan for in November of 2019. The Agreed Order and other documents are on the Emerald Gateway cleanup webpage.
