Additional Property Attributes

The property began as a saltery in 1929. In 1939 it was upgraded to a saltery and fish meal plant. According to a 1939 United States Survey 2496 it consisted of fuel oil tanks, meal plant, boilers, herring oil tanks, two warehouses, six above ground diesel tanks, rooming house, mess house, bunk house, two cabins, and a radio cabin. The area was heavily impacted by the 1989 Exxon Valdez Oil spill and weathered oil remains on the beach and in the tideland. An additional diesel spill occurred in September of 1989 which also impacted Thumb Bay. A study was conducted in 2003 to identify, map, and quantify polynuclear aromatic hydrocarbons (PAH) in sediments along shorelines of the Prince William Sound. This property was one of the sites investigated. 2,540 square meters of PAH-impacted sediment were identified in the study. A phase two environmental site assessment (ESA) was conducted in 2004. The ESA documented historic petroleum releases to the surface soil from bulk fuel storage, miscellaneous petroleum storage, and flaking lead-based paint from tanks. Petroleum and lead were found about the applicable DEC cleanup levels in surface soils. Contamination may have migrated into the subsurface soil, groundwater, sediment and surface waters. Minimal cleanup of scrap metals and solid waste took place in 2015. EPA conducted a Targeted Brownfields Assessment in 2021 and identified multiple RECs that required additional characterization. Soil, groundwater, and surface water was sampled for contaminants of concern. Additionally, inventory of unlabeled drums, tanks, and other containers and a hazardous building material assessment was completed. DEC provided additional site characterization activities in 2022-23 building on work performed on the TBA. Surface soil, surface water, and groundwater samples were collected. Background metals samples and a bedrock investigation also occurred during the 2022 field sampling. Surface soil concentrations were detected above state cleanup levels in several areas. Additional soil delineation and groundwater sampling is recommended for 2023 field season.
