Public Comment Period for Permit Modification to Allow for Disposal of Mixed Low-Level Waste at the Integrated Disposal Facility

The U.S. Department of Energy is providing notice of a 60-day public comment period on a Class 3 proposed modification to the Hanford Facility Dangerous Waste Permit. This proposed modification would support operations and allow for disposal of mixed low-level waste in both disposal cells of the Integrated Disposal Facility, add receipt of mixed low-level wastes from Hanford Site operations, and allow for the construction of a treatment pad and a storage pad.

The comment period is from Dec. 16, 2019, to Feb. 14, 2020.


A public meeting will be held Jan. 21, 2020, at 5:30 p.m. at the Richland Public Library, 955 Northgate Drive, Richland, WA 99352. If you are unable to attend in person, you can participate via webinar, ID#619-229-539.
