Environmental Settlements - Oil Accountability

Projects

Each dam has operational similarities and common internal processes and equipment. The management, equipment, project layout, staffing and size, however, vary among the projects.

Each project is subject to Northwestern Division policy on oil and grease accountability to ensure that oil and grease at operating projects are properly accounted for to reduce the potential for releases of pollutants into waters of the United States.

Each project uses the Facility Equipment Maintenance (FEM) tracking system to document all equipment inspections and repairs. Inspections are performed on a routine schedule established by the individual dam. When Inspections reveal operation or maintenance issues not associated with normal operations, the project performs Assessments through which the project evaluates, repairs, or otherwise addresses such issues. The reports below contain summaries of Inspections and Assessments for each of the eight dams.

Columbia Riverkeeper - 2014 Settlement Agreement

Per the settlement agreement in Columbia Riverkeeper v. USACE, No. 2:13-md-02494-LRS (E.D. Wash.), pertaining to the Bonneville, John Day, McNary dams on the Columbia River, the U.S. Army Corps of Engineers is making available reports of monitoring and assessments that have occurred pursuant to an Oil Accountability Plan for each project.

Since EPA issued NPDES permits for *Ice Harbor Lock and Dam, *Lower Monumental Lock and Dam, *Little Goose Lock and Dam, and *Lower Granite Lock and Dam in September 2021, *The Dalles Dam in December 2022, and *Dworshak Dam in September 2023 the settlement agreement no longer requires USACE to publish the reports for these projects on this site.

Chief Joseph Dam - 2019 Offer of Judgment

Per the Offer of Judgment entered in Columbia Riverkeeper v. USACE, No. 2:19-cv-00126-RMP (E.D. Wash.) pertaining to Chief Joseph Dam on the Columbia River, the U.S. Army Corps of Engineers made available reports accounting for all oils and greases delivered to the Chief Joseph Dam to lubricate “in-water” components that may contact the Columbia River (to include the volumes of such oils and greases stored, purchased, used, recovered and disposed of during the prior calendar year) using available information.

Since EPA issued a NPDES permit for *Chief Joseph Dam in May 2023, the Offer of Judgment no longer requires USACE to publish the report for this project on this site.
