The discharge is estimated to have been approximately 63,000 gallons (about 1,500 barrels) of oil. The discharge occurred during a high-flow event, with oil affecting approximately 85 river miles and associated floodplain. The discharge, along with associated response activities, adversely affected natural resources within the jurisdictions of the United States and the State of Montana, the Yellowstone River and adjoining shorelines, including, but not limited to, the floodplain, shoreline, wetlands and other riparian areas, islands, fields, pastures, bottomlands, grasslands and shrublands. This final Programmatic Damage Assessment and Restoration Plan and Environmental Assessment for the ExxonMobil Pipeline Company July 1, 2011 Yellowstone River Oil Spill (restoration plan) has been prepared by the State of Montana and the U.S. Department of the Interior, collectively acting as Trustees for the restoration of natural resources and public use services that were exposed and/or injured by the Yellowstone River oil spill.
