Additional Property Attributes

The Atka Old School Site (the Site) is an approximate 0.90-acre property located in the Old Village portion of Atka, AK. The Site includes the following structures: five inactive 10,000-gallon diesel ASTs, one inactive 8,000-gallon diesel AST, one inactive 4,000-gallon diesel AST, a Former Power Plant, Teacher Housing with an associated 275-gallon steel heating oil AST, a former Community Centergo Hall with an associated inactive 275-gallon steel heating oil AST, and remnants of the Old School Building. The Site is currently owned by the Native Village of Atka.
A Targeted Brownfields Assessment (TBA) of the Site was approved in March 2024. A Phase I and Phase II ESA site visit was conducted in October 2024 along with a limited Hazardous Building Materials Survey (HBMS). The Phase I ESA identified the following recognized environmental conditions: unknown impacts to soil, groundwater, indoor air and surface water from historical site operations (e.g. operation of the diesel power plant, management of coal-related wastes from former coal-fired heating sources, abandoned glycol heat exchanger lines and former drum storage), potential hazardous building materials in Site structures, and potential for impacts of lead-based paint to Site soils.
During the Phase II ESA conducted in October 2024, soil subsurface soil samples were collected from test pits, surface soil samples were collected from building driplines, and surface water and sediment samples were also collected. A limited hazardous building materials survey was conducted on all site buildings except the Teacher Housing. Groundwater samples were not collected, as groundwater was not encountered in test pits prior to hitting bedrock. Soil vapor sampling was not conducted as there were equipment limitations on the flight to Atka.
Several volatile organic compounds (VOCs), total petroleum hydrocarbons (TPH)-gasoline range organics (GRO), and TPH-diesel range organics (DRO) were detected in soils near the onsite ASTs and Old Power Plant area at concentrations above ADEC Method 2 Cleanup Criteria for migration to groundwater (ADEC 2023). It is believed that the migration to groundwater pathway at the Site is incomplete based on Site geology, however, the Alaska Department of Environmental Conservation (ADEC) may require additional data to confirm that assumption. There is a potential for vapor intrusion to indoor air for the Teacher Housing based on the presence of petroleum contamination identified in Site soils.
Soils throughout the Site had detected arsenic, antimony, thallium, lead, and mercury at concentrations above ADEC Method 2 Cleanup Criteria (over 40-inch precipitation zone) for migration to groundwater and human health and/or EPA Regional Screening Levels (RSLs). Lead was detected in certain driplines attributed to lead-based paint (LBP) and antimony, arsenic, lead and mercury were detected in one discrete location attributed to coal ash residue. ADEC may require additional sampling to determine the background concentrations of metals for the Site to evaluate if there are additional concerns related to metals in soils. Additionally, cadmium and antimony were detected in surface water above the ADEC groundwater cleanup criteria and/or EPA RSL at upgradient and cross-gradient locations, although they were not above these screening levels at downgradient locations, suggesting that the source is upgradient from the site.
Asbestos-containing Building Materials (ACBMs), LBP, and mercury-and PCB-containing components found within the Site?s structures may pose a risk to current and future Site users and the environment.
An Analysis of Brownfields Cleanup Alternatives (ABCA) was developed in May 2025. For metal-contaminated soil and hazardous building materials, it was recommended to completely remove all hazardous building materials with a licensed hazardous material abatement, demolish site structures, and remove metal-contaminated soils. A new landfill can eit
