In 2006, the U.S. Coast Guard noticed a sheen on the Penobscot River and traced it back to the Chevron terminal oil facilities located in Hampden, Maine. Numerous discharges of oil and oil constituents to soil, sediment, groundwater, pore water, and surface water (the Penobscot River) at the Chevron Site were documented from 1973 to 2008. The oil and oil constituents caused injury to riverine, wetland and floodplain habitats, groundwater resources, and recreational opportunities, in the vicinity of the Chevron Site. In July 2016, the U.S. District Court of the District of Maine approved a settlement between the State of Maine, the United States of America, on behalf of the Department of the Interior (DOI) and the National Oceanic and Atmospheric Administration (NOAA), and five previous owners/operators of the Chevron Site. The approved settlement provided $880,000 for restoration of natural resources due to discharges of oil from the Chevron Site. a Final Restoration Plan and NEPA Evaluation was released to the public in January, 2020. The Trustees Preferred Alternative was to implement four restoration projects to improve riverine habitat in the Penobscot River Watershed.
