Site Characteristics

General Site Description: The site is generally flat and a flood-control levee separates the upland from the adjacent tidal mudflats of the Lewis and Clark River. The approximate ground elevation of the site is 5-8 feet above mean sea level.
Site History: AMCCO was founded in 1924 to manufacture and repair wooden-hulled fishing and ferry boats, tugboats, and yachts. During World War II, the shipyard added larger shipways and expanded operations for construction of military vessels. During the Korean Conflict, and the Vietnam War, the company built wooden-hulled minesweepers and subchasers. In addition, AMCCO refurbished previously mothballed warships. During the peak production period from 1940-1960 the facility employed more than 400 full-time workers. In the 1960s, work for the U.S. Navy decreased and operations transitioned toward fishing and tug boat repair. After 1985, AMCCOs business primarily involved repairs of fishing boats.
Contamination Information: (3/4/97 GMW) Based on a written complaint about improper waste management at this ship sandblasting and repair facility, staff from DEQ's Northwest Region visited the site in June 1996. The inspectors found several piles of sandblast grit at the site, and collected samples from each; DEQ's lab found that the "old" grit pile qualified as an Oregon-only hazardous waste, since it failed the Aquatic Toxicity test (likely due to tributyl tin). The waste grit came from sandblasting operations in several building near the Lewis & Clark River. DEQ also found petroleum contamination in on-site surface water, especially in an area around a building that housed leaking hoist motors. (GMW 6/25/97) A site visit for CRL eligibility found the grit piles removed, but areas of residual grit in several locations. There was also an area of oil-soaked soil underneath some above-ground waste-oil storage tanks. The owner of the business also indicated the possibility that pre-1950 operations in the docks along the Lewis & Clark River caused sediment contamination there. About 8 feet of silt have accumulated in these docks since that time.

(8/24/09 smf) EPA completed a Site Inspection of the site in 2007-08, encountering elevated concentrations of tributyltin (TBT), metals, petroleum, PAHs and other SVOCS, and BTEX in the site's surface soils and waste sandblast grit; TBT, metals, and BTEX in the site's shallow groundwater; and TBT, metals, and petroleum in Lewis & Clark River sediments along the site.
Manner and Time of Release: Disposal of sandblast grit on-site, and into the Lewis and Clark River; sandblasting operations over open water (larger ships that don't fit into building). Time of release: 1924 to 1996. Also burning of site refuse at the burn area on the dike north of the ship buildings.
Hazardous Substances/Waste Types: Tributyl tin, RCRA metals, petroleum hydrocarbons, PAHs, other SVOCs, BTEX, PCBs, and dioxins.
Pathways: The site is located on Jeffers Slough and the Lewis and Clark River, and is within 1 mile of Youngs Bay. Ecological exposure to sediments and human fish consumption are the primary aquatic pathways of concern. Site contaminants of concern are also widespread in shallow soil across the upland portion of the site, particularly at the former burn area, north of the ship building. Direct contact with soil is another primary pathway.
Environmental/Health Threats: Anadromous fish species, bottom-feeders, and wildlife that feed on them could be threatened by contaminants flushed from the site into Jeffers Slough or the Lewis and Clark River. Worker contact with site soil also represents a health threat.
Status of Investigative or Remedial Action: (GMW 6/25/97) Characterization of residual grit piles, oil-stained areas, and dock sediments is needed to evaluate threats to ecological receptors. The biggest concern is waste sandblast grit with embedded paint chips, which most likely contains tributyl tin, copper, and other compounds designed to kill aquatic and marine organisms, as demonstrated by the 100 percent mortality result in an Aquatic Toxicity Test on the spent grit. Following the RI and endangerment assessment, remedial action(s) should be carried out to ensure long-term protection of the environment. Further state action at this site warrants a medium priority. AMCC should be added to the Site Response Waiting List and added to the Confirmed Release List.

(8/24/09 smf) A 2007-08 SI by EPA confirmed the presence of elevated concentrations of TBT and metals in Lewis & Clark River sediments; and TBT, metals, petroleum, PAHs, other VOCs, and BTEX in site soils. Site groundwater was contaminated with TBT, metals, and BTEX. Further investigation and cleanup are needed.

(7/21/15 RKW/SR) In March 2011, EPA had proposed the site for inclusion on EPA’s list of most contaminated sites in the nation, the Superfund National Priorities List. In September 2012, EPA deferred the site listing and transferred site management to DEQ. AMCCOs contractors performed a remedial investigation in two phases from 2013 to 2015. The RI (including a risk assessment) and the FS were submitted in May 2015. Comments on the RI/FS were submitted in July 2015.

(12/7/16 RKW/SR) DEQ requested modification of the FS to include a cleanup alternative that would preserve the ship rails so the facility could continue operations. An economic analysis of the business was also requested to help with DEQ remedy selection. Revised FS in February 2016 included a ship rail preservation option but it was very costly. The economic analysis concluded that long-term profitability was unlikely due to long deferred maintenance in light of the upcoming cleanup. DEQs Staff Report was released April 15, 2016. The proposed remedy included excavation of on-site hot spot soil as well as hot spot sediment for consolidation below a concrete cap behind the dike. Remaining upland soil contamination was to be capped with gravel and remaining sediment contamination covered with a 6 inch sand layer. Many of the comments received emphasized the importance of the shipyard to the local fishing community.

After the comment period a letter was received from Clatsop Economic Development Resources (CEDR) proposing 5-10 year moratorium on the cleanup and subsequent closure of the AMCCO facility. After much input from community DEQ agreed to grant the site owner a deferral on cleanup, now to be completed within 5 years of signing of the ROD. This will give the community more time to plan for a replacement facility following cleanup.

In August 2016 DEQ met with representatives of the Yakama Nation in Toppenish, Washington to discuss their concerns with the proposed remedy. Their primary concern was the future inevitable sea level rise due to climate change and the subsequent inundation of the on-site soil cell containing the site waste. DEQ later agreed to change the remedy to off-site disposal of the hot spot soil and sediment. Other aspects of the rememdy would be unchanged.

In February 2017 DEQ issued the Record of Decision, which details the selected cleanup for the AMCCO site.
