Comment Period

Closure Unit Groups at T Plant and Central Waste Complex

Hanford Dangerous Waste Permit

Sept. 21, 2020 - Nov. 4, 2020, 11:59 p.m.

We're reopening this 45-day public comment period addressing proposed modifications to the Hanford Dangerous Waste Permit. We decided to reopen this public comment period because we discovered that one of the permit documents was unavailable to the public on our website. 

The permittees are the U.S. Department of Energy and co-operated by CH2M Hill Plateau Remediation Company. The T Plant Complex and Central Waste Complex are located on the Hanford Site in Southeastern Washington.

Review and comment

The modification proposal and supporting documents are on our Hanford public comment periods page.

Proposed changes

The proposed modification is to close seven container storage areas (unit groups) listed below. The unit groups are going into the Site-wide Permit part 5, as closure unit groups.

  • T Plant 277-T Building, Closure Unit Group 27
  • T Plant 277-T Outdoor Storage Area, Closure Unit Group 28
  • T Plant 271-T Cage, Closure Unit Group 29
  • T Plant 211-T Pad, Closure Unit Group 30
  • T Plant 221-T Sand Filter Pad, Closure Unit Group 37
