YKF NWR - School Underground Storage Tank Assessme

Summary: Background The project is initiated by the U.S. Fish and Wildlife Service (USFWS) for the Yukon Flats National Wildlife Refuge (NWR) located in Beaver, Alaska. The mission of this project is to assess a potential undocumented underground storage tank (UST) at the Beaver BIA School site, which is crucial for environmental safety and compliance with regulations regarding potential contamination from Diesel Regulated Organic (DRO). The goal is to confirm the presence of the UST and evaluate any associated contamination in soil and groundwater. Work Details The contractor will perform the following tasks: 1. Conduct a Ground Penetrating Radar (GPR) survey to detect the presence of an underground storage tank. 2. If a tank is confirmed, conduct a bore scope evaluation of the fill tube to check if it was filled with inert material before abandonment. 3. Perform soil boring sampling around the tank to assess vertical and horizontal contamination levels. 4. Conduct groundwater sampling to determine if contamination exists in groundwater. 5. Analyze samples for Diesel Range Organics (DRO), Gasoline Range Organics (GRO), and other contaminants using specified EPA methods. 6. Prepare a Site Characterization Report and Corrective Action Completion Report detailing findings and recommendations for remediation if necessary. Period of Performance The contract period will commence on July 6, 2026, and conclude by November 30, 2026. Place of Performance The work will be performed at the Beaver BIA School site within the Yukon Flats National Wildlife Refuge, Alaska, which is accessible only by plane or boat. Bidder Requirements Bidders must be small businesses as this solicitation is set aside for small business participation. Contractors must demonstrate qualifications as an ADEC-qualified environmental professional under Alaska regulations, possess relevant experience in conducting GPR surveys and contaminated site investigations. Incumbent Analysis (see Incumbents section for more detail) This opportunity appears to have a confirmed closely related prior contract, 140FS126P0123, awarded to Tanana Commercial Company for $70,811 (05/05/26–12/31/26). The prior work involved contaminated soil and groundwater evaluation at the INNOKO NWR, which aligns with the current requirement to assess suspected contamination and characterize soil and groundwater for DRO if an undocumented UST is detected. Both efforts focus on environmental investigation at National Wildlife Refuge sites and use similar sampling/analytical approaches to determine contamination presence and extent.
