Description: In-line sediment traps were successfully deployed between September and January in three major stormwater discharges to Thea Foss Waterway (Foss Waterway) located in Commencement Bay, Tacoma, Washington. River derived fine surface sediment along the shoreline of Commencement Bay was 77 percent. This finding, in combination with higher concentrations of organic contaminants in marine rather than river sediment, indicates that riverborne sediment-bound contaminants are retained in shallow marine habitats of Commencement : Renee K.

Commencement Bay and Elliott Bay DMMP Sites The Updated Environmental Monitoring Plan (UEMP) includes the current physical monitoring requirements and procedures for the Commencement Bay (CB) and Elliott Bay (EB) sites. A description of these two sites is included in Table and site maps are provided in Figures and Sediment Traps Source Control / Monitoring Whole Water Monitoring Business Inspections Spill Response Source control Investigations and Enforcement 8 1. Scrub the storm system to remove chronic contaminants • $,/year • 75 tons removed • • 28 miles/year • $13,/mile of pipe • Enhanced Maintenance 2. Remove more sediment from. As part of Ecology’s Urban Bays monitoring program, Commencement Bay surface sediments were sampled in , , and Sediment condition was evaluated with calculated indices based on results of laboratory analyses. In , a cooperative agreement was forged between the PSAMP Sediment Component and NOAA's National Status and Trends (NS&T) Program to conduct sediment sampling in .
EPA’s summary of tier 1 sediment remediation sites with pre-monitoring and post-monitoring data (S. Ells, EPA, unpublished information, Ma ) presented during the committee’s first meeting indicates that the baseline average concentration of PCBs in surface sediment (no depth specified) at the hot spot mg/kg and lists a.

Historically, sediment quality assessment has been an important feature of many California monitoring programs. It was a major focus in the Bay Protection and Toxic Cleanup Program (BPTCP; Anderson et al. ), the California Environmental Mapping and Assessment Program (EMAP; USEPA ), the San Francisco Regional Monitoring Program (SFEI ). The toxicity of sediment samples from Commencement Bay, Washington, was measured by the survival of marine infaunal amphipods (Rhepoxynius abronius) during ten-day exposure to test sediment.
