Event: 30-Day Public Comment Period on the Engineering Evaluation/Cost Analysis for the PUREX Complex
Category: Public Comment Periods
Event Date: July 3 - August 2

This is a message from the Tri-Party Agreement Agencies.

The U.S. Department of Energy Richland Operations Office is holding a 30-day public comment period on an Engineering Evaluation/Cost Analysis (EE/CA) for the Plutonium Uranium Extraction Complex (PUREX), located in the 200 East Area of the Hanford Site.

The EE/CA describes the proposed non-time-critical removal action options for PUREX and its attached annexes (202A Canyon, 202A East Annex and 202A West Annex). The removal action does not pertain to PUREX Tunnels 1 and 2, which were recently filled with grout for interim stabilization. A summary fact sheet is attached.

Emission units associated with PUREX covered in this EE/CA will be transitioned from the Hanford Air Operating Permit to CERCLA authority as specified in the CERCLA transition process detailed in the Air Operating Permit.

The 30-day public comment period is July 3 to August 2, and the EE/CA is available on Hanford Administrative Record, and at the Hanford Public Information Repositories.

Please submit written comments by August 2 to or by mail to:

U.S. Department of Energy
P.O. Box 650, H1-20
Richland, WA  99352

After considering the comments received from the public, DOE will confer with Washington State Department of Ecology and issue a final decision, called an Action Memorandum. Once the Action Memorandum is complete, DOE can perform the selected cleanup action.

Questions? Contact Paula Call, DOE, at, or (509) 376-2048.
