J.E. McAmis, Inc., has just announced that the company is working on pile removal and in water sand capping of the Astoria Marine Construction Company (AMMCO) site in Astoria, OR.
The site is contaminated with hazardous chemicals from historical ship manufacturing and repair operations.
Contamination is in soil on the property and in nearby riverbed sediment in the Lewis and Clark River near the mouth of the Columbia River.
In coordination with AMCCO, tribal governments, and a community advisory group, DEQ selected a remedy in 2017 to clean up contamination on the site and in the adjacent riverbed.
AMCCO has started demolishing activities of onsite buildings and structures in preparation for performing the cleanup and sand capping operations that are currently underway.
McAmis is providing the marine side work in support of the larger effort being managed by DEQ and Maul Foster & Alongi.
AMCCO is implementing the cleanup remedy with DEQ oversight. The cleanup will be complete by November 2020.
