Integrated Disposal Facility permit modification

Hanford Dangerous Waste Permit

Sept. 13, 2021 - Oct. 28, 2021, 11:59 p.m.

We're holding a 45-day public comment period addressing proposed modifications to the Hanford Dangerous Waste Permit for the Integrated Disposal Facility (IDF).

The permittees are the U.S Department of Energy, Richland Office and the Central Plateau Cleanup Company. IDF is 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

This draft permit modification for the existing IDF Operating Unit Group 11 incorporates new and modified information that includes the addition of three dangerous waste management units: 

  • Operation of an additional disposal cell 
  • Storage area
  • Treatment area 

The draft permit also provides detailed information to support the operation of IDF.

For more information see the Nuclear Waste Program public comment page.

IDF background

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. Leachate will be monitored, collected, and treated as needed.
