The U.S. Department of the Interior, through the U.S. Fish and Wildlife Service, is soliciting bids for the removal and replacement of a diesel fuel storage tank at the Green Lake National Fish Hatchery in Ellsworth, Maine. The project entails replacing an existing 2,000-gallon above-ground tank with a new 1,000-gallon tank, including the removal of the old tank, installation of the new tank, and reconnection of supply lines for an emergency generator. This upgrade is crucial for maintaining operational efficiency and safety standards at the hatchery, which will continue operations during the project. Interested contractors should note that quotes are due by January 13, 2026, with a site visit scheduled for January 7, 2026, and all inquiries must be directed to Christa Garrigas at christa_garrigas@fws.gov by January 8, 2026. The estimated construction cost is between $25,000 and $100,000, with work expected to commence on January 20, 2026, and conclude by February 20, 2026.
