The Engineering Forum (EF), established in the late 1980s, is a group of engineers and scientists that supports the Superfund and RCRA programs in each of the ten EPA Regional Offices. As one of the EPA Technical Support Project’s (TSP) three technical forums, the EF is a medium for exchanging technical information regarding innovative site cleanup and characterization technologies. Monthly technical talks focus on site-specific engineering problems encountered, alternatives and solutions, and lessons learned. After each presentation, information regarding upcoming events and training are discussed and time for an Open Mic discussion is provided. If you are a Superfund, Resource Conservation and Recovery Act (RCRA), Brownfields, state or federal environmental professional who is interested in solving technical issues, register for any technical talks listed below that interest you and join the discussion!

Presentations are specifically designed for EPA staff including RPMs, OSCs, Corrective Action Managers, Superfund and Technology Liaisons, Chemists, Biologists, Physical Scientists, and Engineers from within EPA regions, program offices, laboratory system, and headquarters personnel as well as environmental professionals from state agencies, tribes, the U.S. Army Corps of Engineers, U.S. Dept. of Energy, and other federal agencies of all experience levels. THIS TRAINING IS NOT OPEN TO ACADEMIA, CONTRACTORS, CONSULTANTS OR OTHER PRIVATE ENTITIES.

We will try to meet any special accommodations necessary for our participants as possible if given a minimum of two weeks notice. You will be prompted to indicate if you need any special accommodations upon registering for these events.

*This training is offered free of charge to all registrants who are confirmed to attend. One CLP will be issued for each session attended when you register and log on with the registration link provided to enable your attendance to be confirmed.*
 

Region 10 Remedial Project Manager Jacob Moersen will present on the Wyckoff/Eagle Harbor Superfund Site located in Bainbridge Island, Washington. Located only a short ferry ride from Seattle, the former wood treatment facility began operations in the early 1900s and grew to become one of the largest producers of creosote- and pentachlorophenol-treated wood in the country. Federal and state agencies began investigating in the early 1980s after receiving reports of cancerous lesions in fish and elevated PAH concentrations in sediment. The site was listed on the National Priorities List in 1987 and the facility ceased operations shortly thereafter.

An RI/FS was completed in 1991 and followed by a series of removal actions in the mid-1990s to stabilize the Site. A 2000 Record of Decision called for a reinforced sheet pile wall to support steam-enhanced extraction in the upland. Unfortunately, a robust thermal pilot study failed to meet objectives, and the contingency remedy of capping and groundwater treatment was mired in controversy. EPA recently issued two Record of Decision Amendments (RODAs) for the Site. The 2018 RODA identified road improvements, beach dredging and capping, and replacement of the failing sheet pile wall. The 2019 RODA selected in-situ stabilization/solidification (ISS) of 250,000+ cubic yards of contaminated soil in the upland along with a slurry cutoff wall and low-permeability vegetated cap. Upon completion of cleanup activities, the Site will be transformed into a public park.

This presentation will provide an overview of ongoing activities, including the following:

• Lessons Learned: DES task order acquisition, award and kickoff for beach and upland design.
• Schedule and Sequencing: Planned DES design and RES construction activities including integration with the replacement wall being led by the U.S. Army Corps of Engineers.
• Risk Management: Remediation risk register and/or climate vulnerability assessment screening.

A connection link for this training will be included in the automatic registration receipt emailed to you immediately after registering for this training. We recommend adding this link to your calendar as soon as you receive it, being careful to note the correct time zone for the training - Eastern Standard Time in case of this training.
