Time Oil Seattle Terminal
Client: Cantera Development Group
Overview of Floyd|Snider Contributions
Project Summary
Floyd|Snider was retained by Cantera Development Group in mid-2018 to facilitate cleanup and redevelopment of a vacant, 10.
In coordination with Ecology, we identified and filled key data gaps for design of a cleanup action and prepared a supplemental RI/FS for site-wide cleanup. The cleanup action included remediation of seven distinct operational areas in upland and shoreline areas of the Site, utilizing a combination of excavation, in situ stabilization, and in situ groundwater treatment to address multiple indicator hazardous substances in soil and groundwater.
The cleanup action development and construction were completed on an expedited timeline to accommodate the anticipated site redevelopment activities. The primary project milestones of the final Prospective Purchaser Consent Decree and construction completion were achieved over a time period of less than 4 years from initial engagement, amid regulatory agency and supply chain disruption caused by the global COVID-19 pandemic.

Our Approach
Our expertise in establishing cleanup standards under the Model Toxics Control Act allowed Floyd|Snider to streamline the cleanup by combining properties that had previously been addressed separately under the Ecology cleanup process into one holistic site, with indicator hazardous substances to define the key contaminants and cleanup areas driving risks to environmental receptors.
Our strategic approach to integrating cleanup and future site use goals included prioritizing remedial technologies such as in situ stabilization to achieve contaminant mass reduction without future operation and maintenance and additionally improve soil geotechnical conditions for future building construction.
Floyd|Snider leveraged our strong teaming relationships to partner with regional experts in the selected remedial technologies, ensuring efficient design and construction of the cleanup action. We continue to coordinate closely with Ecology to adaptively manage long-term monitoring of the site following cleanup action construction, collecting key performance data while minimizing costs.
Project Milestones
2020. Final Prospective Purchaser Consent Decree
2022. Cleanup Action Construction Completion
Our Approach
Floyd|Snider worked closely with Ecology and the client throughout the cleanup process to ensure that the cleanup met the dual goals of protection of human health and the environment and property redevelopment.
