Summary Information

The Astoria Marine Construction Company, or AMCCO, site is located along the Lewis and Clark River near Astoria, Oregon. In 2012 EPA deferred a Superfund listing of AMCCO with the condition that DEQ lead the remedial investigation and cleanup. The site and adjacent river sediments are contaminated with tributyltin and heavy metals from ship refurbishing operations since 1926. AMCCO completed a Remedial Investigation and Feasibility Study in May 2015 and presented the results, along with a draft feasibility study, to DEQ and the Community Advisory Group. The Feasibility Study proposed cleanup options requiring curtailment of the site’s current shipyard activities. DEQ advised the company that options presented in the feasibility study fail to meet criteria regarding current and future uses of the site, and requested AMCCO to develop a long-term business plan to ensure the shipyard selects appropriate cleanup options that comply with DEQ cleanup standards. During 2016, DEQ continued coordination with tribal representatives and the CAG to get their review and input on the Staff Report (DEQ proposed plan) for the remedy at this cleanup site.
DEQ issued the Record of Decision (ROD) for the cleanup remedy in February 2017, which incorporates comments provided by Tribal governments and the community of Astoria. DEQ coordinates with natural resource trustees including Federal, State, and representatives from four Tribes. Restoration could occur as early as next summer and remedy implementation in 2019. DEQ will continue to communicate with trustees and the community on project milestones, and to ensure concerns are considered during remedy design and construction.
In October 2018, DEQ sought public comment on its proposed agreement to clean up historical contamination at Astoria Marine Construction Company, or AMCCO. Under the agreement, AMCCO will implement the cleanup remedy identified in DEQ’s 2017 Record of Decision and will be released from further liability. DEQ will perform maintenance of the in-water area, using DEQ orphan program funds, after the cleanup remedy is implemented. The cleanup consent judgement (filed March 21, 2019) and site factsheet can be downloaded from the document links below.
In early 2020, Astoria Marine Construction Company started demolishing activities of onsite buildings/structures in preparation of performing the selected cleanup in in the Summer. Upland cleanup activities began in June and in-water cleanup in July. The majority of the cleanup has been completed as of November 2020; however, the north yard cap and additional stormwater upgrades will be completed in Summer 2021.
