Current Issues

SMARM 2018 marked the 30th Sediment Management Annual Review Meeting of the multi-agency Dredged Material Management Program (DMMP).  Originally referred to as the Puget Sound Dredged Disposal Analysis (PSDDA) program, the now-statewide DMMP continues to evolve with current science and policy.  This page is dedicated to documentation of current issues as the evolution continues.

Monitoring Ideas Workshop: June 20, 2018

Why are we doing this?

This workshop is a continuation of the process we have been engaged in for the last several years to more effectively address bioaccumulatives in the Dredged Material Management Program.  Over the last several years a number of factors have come together indicating a need for the DMMP to explore these issues, including: project-related issues, emerging science on the effects of bioaccumulatives to higher trophic levels and Endangered Species in Puget Sound, and changing policy such as Ecology's 2013 Sediment Management Standards rule revision. This process has been an evolving journey, as DMMP agencies and public stakeholders alike have gathered information, explored existing data, and discussed various options for moving forward.

What have we done so far?

At the 2016 Sediment Management Annual Review Meeting (SMARM), we discussed the origins of the Dredged Material Management Program, including Site Condition II and how bioaccumulatives were addressed during PSDDA.  At the 2017 SMARM we looked at issues and challenges related to bioaccumulatives and reviewed the current DMMP dredged material guidelines and monitoring procedures for bioaccumulatives.  Mounting interest let to a workshop in November 2017 (details below) on bioaccumulatives.  Based on input given at the November workshop we were encouraged to review existing monitoring data to identify problems and data gaps.  At the 2018 SMARM we focused on disposal site monitoring and the monitoring framework, including both strengths and weaknesses of the current monitoring approach.   Preliminary ideas for potential improvements to the monitoring plan were presented and discussed.

We want your ideas!

As a next step in the process of addressing bioaccumulatives at the dredged material disposal sites, we want to hear your ideas!  All ideas regarding monitoring questions, measurement techniques and endpoints, ways to assess bioaccumulatives, and anything else related to open-water disposal site monitoring are welcomed and encouraged.  The workshop will be run by an outside moderator and run as a brainstorming event, focused on coming up with ideas and absent of judgement.  We will provide some history and context at the beginning of the workshop.  We hope you will join us!  

Details

The workshop will be held on June 20th, 2018 from 9am to 12pm at the Port of Tacoma's Fabulich Center, Room 110.  Click here for the workshop flyer.

Stakeholder Discussion: November 1, 2017

An interactive discussion between the DMMP agencies and stakeholders was held on Wednesday, November 1, 2017, to explore the regulatory foundations of the Dredged Material Management Program and how those relate to emerging science and changing regulations.  Click on links below for PDF documents.
