Event: Ecology Led 45-day Public Comment Period on Proposed Modification to PUREX Storage Tunnels
Category: Comment Period / Feedback Opportunity
Event Date: Aug. 13 – Sept. 27, 2018

This is an Ecology led public comment period.

Second Comment Period on Proposed Modifications to PUREX Storage Tunnels
August 13, 2018 – September 27, 2018

Ecology invites you to review and comment on this proposed permit modification to the Sitewide Permit. The proposed permit modifications affect the PUREX Storage Tunnels located on the Hanford site. The tunnels store waste, mostly large equipment components, from the PUREX Plant and other onsite sources. By completing the response action for Tunnel 1 and the proposed interim closure action for Tunnel 2, the tunnels will continue to safely store the waste.

The proposed changes include draft permit language reflecting the response actions taken to grout Tunnel 1 and the proposed interim closure action for Tunnel 2. The draft changes include a proposal to fill Tunnel 2 with engineered grout to help mitigate potential threats to human health and the environment. This will not preclude remedial or final closure actions until future cleanup decisions have been reached. Because the tunnels will no longer accept waste, this proposed permit modification will add the PUREX Storage Tunnels as a closing unit to the Hanford Facility RCRA Permit, Revision 8c.
