Terminal 91 Ecology Cleanup site – This site is regulated under both a dangerous waste permit
and a Model Toxics Control Act Order. Cleanup of the upland portion of the site was completed
in 2015 and long-term operation and maintenance, cover inspection and compliance
monitoring has begun. The Order also requires investigation and cleanup of newly discovered
upland discrete units.
Terminal 117 Sediments, Bank and Uplands – EPA identified the Port’s Terminal 117 in South
Park as an Early Action Area. The T-117 cleanup and now long-term monitoring work is
performed by the Port with a cost sharing agreement with the City. The upland and sediment
cleanup actions along with interim restoration of the site at T-117 were completed in 2016.
Long-term monitoring and maintenance of the site began in 2017/18, which includes annual
upland inspections, biennial sediment sampling, and annual reporting. Inspection of the
adjacent city stormwater system in the neighborhood is performed by the City.
Terminal 30 Cleanup – Terminal 30 supports an active, in-situ groundwater treatment system
consisting of air sparging, soil vapor extraction, free-phase petroleum product recovery, and
treatment of recovered vapors under an Ecology MTCA Consent Decree. The Port completed
construction of the treatment system in 2019 and began operations in September. Long-term
operation, maintenance and monitoring of the treatment system is expected to continue for
several years.
