Tri-Party Agreement Agencies announce groundwater cleanup plan at Hanford


From the Tri-Party Agreement Agencies:

The U.S. Department of Energy and the U.S. Environmental Protection Agency, with concurrence from the Washington Department of Ecology, have issued a Record of Decision (ROD) to address groundwater contamination on the Hanford Central Plateau.

A ROD is an important legal document that explains which remedies will be used to clean up contamination under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).

The ROD identifies the cleanup approach that will be used to address groundwater contamination in the Hanford Central Plateau in an area known as the 200-UP-1 Operable Unit.

Alternative 3 (35 years Active Remediation, Monitored Natural Attenuation, Hydraulic Containment, and Institutional Controls) was selected as the cleanup remedy.

Comments received on the Proposed Plan during the July-August 2012 public comment period were considered before finalizing the cleanup decision identified in the ROD.

Part III of the ROD is the Responsiveness Summary, which summarizes the public comments received and provides agency responses to those comments.

The ROD is titled Record of Decision (ROD) for Interim Remedial Action Hanford 200 Area Superfund Site 200-UP-1 Operable Unit and is available here.
