    Abstract

    Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also referred to as Superfund, contaminated bottom sediments were remediated in the Thea Foss and Wheeler-Osgood Waterways in Tacoma, Washington under the oversight of the Environmental Protection Agency (EPA) at a cost of $105M.  Sources of Contaminants of Concern (COCs) continue to exist in the drainage basins and are conveyed to the waterways via stormwater (municipal and private), aerial deposition, marinas, and groundwater discharges. 

    Since stormwater is one of the potential sources, the City of Tacoma is implementing a stormwater source control program (started in 2001) to protect the quality of waterway sediments and the integrity of the cleanup.  The program is supported by post-construction sediment quality monitoring; stormwater, base flow, and storm sediment monitoring; and a validated contaminant transport model of the waterway (EPA WASP model).  Contaminants of concern in waterway sediments include polycyclic aromatic hydrocarbons (PAHs) and bis(2-ethylhexyl)phthalate (DEHP).  These contaminants are associated with various ongoing sources including municipal stormwater, marinas, atmospheric deposition, and groundwater discharges, many of which are common or ubiquitous in modern urban environments.  The WASP model predictions in Thea Foss Waterway show excellent agreement with seven years of observed post-construction sediment quality data, validating the ability of the model to link pollutant loads to sediment concentrations, and predict the effects of source control actions on waterway sediment quality. 

    The City’s multi-pronged stormwater source control program consists of best management practices, business inspections, public education, source tracing investigations, and stormwater treatment.  Over the 15 year period (August 2001-September 2016), these efforts have resulted in statistically significant reductions in suspended sediments, lead, zinc, PAHs, and DEHP, in spite of the inherently high variability of stormwater data.  In recent years, the City performed basin-wide street sweeping and system-wide storm sewer cleaning in selected drainages to remove residual contaminated sediments that may continue to degrade stormwater quality. Street Sweeping and system-wide sewer cleaning resulted in statistically significant reductions in PAHs and metals.  Finally, the City developed a GIS-based pollutant loading model of its urban drainages (HSPF model) to evaluate the cost-effectiveness of various treatment technologies and management practices for reducing pollutant loads in stormwater; including in-line treatment vaults, street sweeping, and low-impact development (LID).  The model results identify areas and land uses that contribute disproportionately to stormwater pollution, where source control efforts are best focused, and recommendations for cost-effective source control investments.

    2017 AWRA Washington State Conference

    The 100 Year Anniversary of the Washington Water Code: Where We Came From and Where We’re Going

    October 3, 2017

    8:00 AM to 5:00 PM

    (Reception 5:00 to 7:00 PM)

    Mountaineers Seattle Program Center

    7700 Sand Point Way NE, Seattle, WA

     

    The AWRA-WA welcomes you to join us for an interdisciplinary investigation of Washington water from adjudication to technical analysis.  This year’s conference includes an intriguing reflection of the past 100 years of the Washington Water Code, its implementation, and a look forward to the next 100 years.  Stresses from population growth and increasing uncertainty from climate change will test the state’s ability to manage an over allocated resource.  How will we adapt? Do we have the technical and policy tools to meet the challenges ahead?


    AWRA-WA is proud to announce keynote speaker Charles Wilkinson – Distinguished Professor, Moses Lasky Professor of Law at the University of Colorado School of Law.  For his full bio, please click the image below.


    Professor Wilkinson will present:  Western Water Law and Policy in the Modern Era: Has Washington Made the Needed Changes?

     

    Our conference program includes the following five sessions:


    Session 1: Early Water Code History – Reflecting on the historic cultural significance of water from time-immemorial through early statehood, including the early history of water right appropriation, establishment and development of the surface water code from 1917 through the Water Resources Act of 1971.  This is the era of water appropriation.

    Moderator: Andy Dunn, RH2

    Pre-Water Code History- Tom Ring, Yakama Nation

    Water Code History- Tom McDonald, Cascadia Law Group

     

    Session 2: Contemporary Water Code History – Marking the change from water right appropriation to recognition of competing needs, including protecting the quality of the environment and the natural interrelationships of surface and ground waters, this session will reflect on establishment of the instream flows, management of water resources, and quantification through adjudications and market-based reallocation.

    Moderator: Dave Christensen, Department of Ecology

    Water Management and Instream Flow- Ken Slattery, retired from Department of Ecology

    Protecting Instream Flow- Hal Beecher, retired from Department of Fish and Wildlife

    Adjudication and Reallocation- Bob Barwin, retired from Department of Ecology


    Session 3: Defining Future Risks – The water code must be able to respond to changes in water availability, water demand, population, and climate.  This session will discuss some of the technical, legal, and social issues that will drive future water management and the need for collaboration and adaptability.

    Moderator: Steve Hirschey, King County

    Water Availability and Reliability: Legal Perspective- Peter Dykstra, Plauche & Carr LLP

    The Public Interest and the Future of Water Law- Rachael Paschal Osborn, Attorney at Law

    Future Out of Stream Supply and Demand- Jennifer Adam, Washington State University


    Session 4: Identifying Possible Solutions – Future solutions to challenges in water resources may be found in current actions that work with today’s code; this session will look at conflict resolution, legal water right certainty, and solutions through infrastructure, including storage and conveyance.

    Moderator: Tyson Carlson, Aspect Consulting

    Conflict Resolution- Lynette de Silva, Oregon State University

    Achieving Legal Certainty- Adell Amos, University of Oregon

    Storage – J. Ryan Brownlee, Aspect Consulting, LLC

    Methow Valley Irrigation District- Lisa Pelly, Trout Unlimited


    Session 5: Panel on Legislative Change and Funding Needs – Our conference concludes with a facilitated panel including representatives from agency, legislative, and stakeholder groups discussing what changes need to be made to water management and the water code, and how they will be supported and funded in a time of shrinking state and federal budgets.

    Moderator: Adam Gravley, Van Ness Feldman LLP

    Charles Wilkinson, University of Colorado

    Scott Revell, Roza Irrigation District

    Derek Stanford, Representative of 1st Legislative District
