We are holding a 45-day public comment period addressing proposed modifications to the Hanford Dangerous Waste Permit, for the Integrated Disposal Facility (IDF).
We are reopening the public comment period to allow the public to comment on the changes made based on public comments received during our previous public comment period in 2021.
This public comment period will address a Class 3 permit modification to the IDF portion of the Dangerous Waste Permit. This modification:
- Adds three dangerous waste management units (an additional disposal cell, a storage area, and a treatment area) to IDF.
- Provides detailed information which supports operation of the facility.
Located on the Hanford Site, IDF is an engineered disposal facility geared to receiving immobilized low-activity waste (ILAW) from the Waste Treatment Plant at Hanford, along with other low-level waste from site operations.
IDF is set to be a permanent disposal site for the ILAW containers, along with other mixed low-level waste streams. The facility currently has two disposal cells, which can be expanded at a future date.
