Operable Units

Below, EPA has provided a list of the remedial actions selected pertaining to each operable unit.

EPA issues Records of Decision (RODs) to explain which cleanup methods will be used at Superfund National Priorities List sites. EPA has two primary documents that it may use to identify changes to the remedies selected in RODs. EPA uses a ROD Amendment when it needs to make a fundamental change to the remedy. EPA publishes an Explanation of Significant Differences (ESD) for significant changes.

During cleanup, complex sites may be divided into several distinct areas to make the response more efficient. These areas, called operable units (OUs), may address geographic areas, specific problems, or medium (e.g., groundwater, soil) where a specific action is required.

EPA is working to improve data quality. The information presented on this page is undergoing review for accuracy and completeness, and may be subject to change.
