Closure Unit Groups at T-Plant & CWC permit modification

The Washington State Department of Ecology is holding a 45-day public comment period on a proposed agency initiated permit modification to the Hanford Dangerous Waste Permit. On Dec. 6, 2021, Ecology issued Modification No. 8C.2021.1F to the Sitewide Permit. This modification incorporated both Closure Plans and Unit Specific Permit Conditions for several groups within the Solid Waste Operations Complex (SWOC). On Jan. 5, 2022, USDOE and CPCCo appealed the modification to the Pollution Control Hearings Board. In lieu of a hearing, Ecology and the permittees agreed to mediation to settle the dispute. A settlement agreement was reached in October 2022. This permit modification would make additional changes to T-Plant and CWC units based on the settlement agreement.
