Latest information on the Lower Duwamish

Ecology, EPA, King County, and the City of Seattle work continuously to    control sources of contamination to the Lower Duwamish Waterway (LDW). We post the latest source control information on this page, including reports and updates on work underway. 

Ecology screening levels are available for Lower Duwamish Waterway cleanup sites

We released an Excel workbook and white paper (background information and instructions) that provide preliminary cleanup levels (PCULs) for Model Toxics Cleanup Act (MTCA) sites within the Lower Duwamish Waterway drainage area.  The cleanup levels can be used to screen site data to select chemicals of potential concern. They also provide a starting point for developing the final cleanup levels for sites.

Ecology fines Island Tug and Barge $8,000 for 2017 diesel spill

We fined Island Tug and Barge $8,000 for a spill of diesel fuel into the West Waterway on February 28, 2017. Half of the penalty is for the spill itself and half is for not making immediate notifications, as required by state law.
 
The company’s tug Island Wind breached its hull and a fuel tank when it struck a barge, spilling approximately 1,340 gallons of diesel. The company and its contractor, Global Diving and Salvage, mounted a prompt response and recovered 1,273 gallons of the spill. Small, unrecoverable sheens escaped into Elliott Bay. Notification to the state occurred more than 90 minutes after the incident. We also billed Island Tug and Barge $3,000 to recover the state’s costs to oversee the response.

Ecology requests public input on a proposed revision to a water quality policy

We're proposing revisions to Water Quality Policy 1-11. Water Quality Policy 1-11 guides how we evaluate data to make listing decisions on each segment of the water bodies we assess. The results are then submitted to the U.S. Environmental Protection Agency (EPA) for review and approval of the state’s list of impaired waters, also called the 303(d) list. We are updating Water Quality Policy 1-11 to improve the accuracy of assessment determinations and provide better clarity in how the agency makes decisions.
 
For more information, visit Ecology’s website. We are accepting comments from the public on the proposed revisions to Water Quality Policy 1-11 until 11:59 p.m. on March 28, 2018.

Ecology is updating Washington’s rule for hazardous waste site cleanups 

We are beginning an exploratory rulemaking to update the Cleanup Rule. This rule contains regulations for implementing the state’s environmental cleanup law, the Model Toxics Control Act (MTCA). 

We want your suggestions for general rulemaking topics, and for specific changes to any part of the Cleanup Rule. We will catalog your comments and consider them at the most appropriate time during future rulemakings. You will also have opportunities to comment during each future rulemaking.

We also welcome comments on our overall rulemaking approach. To learn more about the exploratory rulemaking process and how you can participate, visit our new Cleanup Rulemaking website.

If you received more than one Cleanup Rule notice, you’re on one or more Ecology e-mail lists. Going forward, we’ll only send Cleanup Rule updates through our MTCA-SMS-Rule-Update listserv distribution list. You’ll need to subscribe to that list to continue receiving these notices.

Not sure if you’ve already subscribed?
If one of your Cleanup Rule emails contains “MTCA-SMS-Rule-Update” in the address field, you’ve already subscribed.  You won’t need to do anything else and will continue receiving these notices. To subscribe: 

Ecology is changing a permit related to the Stericycle Environmental Solutions Georgetown cleanup

Stericycle Environmental Solutions (aka Burlington Environmental) is one of the four parties responsible for cleaning up the West of 4th site. After a recent public comment period, we amended the site's Agreed Order (legal agreement) and approved the first plans for a partial cleanup action and two pilot studies.  With our approval, Stericycle changed their state dangerous waste permit to reference the newly amended Agreed Order. The other three West of 4th responsible parties do not have such permits.

There is no public comment period related to the permit change, but Stericycle is required to notify the public about the change.

For more information, please contact William Beck, Stericycle Environmental Solutions, Inc., (425) 227-6149 or Ed Jones, Department of Ecology, (425) 649-4449 or visit the project website.
