Hanford Sitewide Permit

We are launching a public comment on the draft renewal of the Hanford Sitewide Permit – one of our most important tools for ensuring Hanford’s cleanup supports our mission of preserving clean land, air, and water for our communities.

The permit covers 52 waste sites and facilities at Hanford and is one of our primary resources for overseeing Energy’s treatment, storage, and disposal of hazardous and radioactive waste. Ecology’s priority is to have a current, enforceable, consistent, and implementable permit that is protective of human health and the environment.

The Hanford Site currently operates under the Hanford Sitewide Permit (Permit) Revision 8C. This current Permit is made up of 22 facilties and waste sites, also known as unit groups. The Permit also includes standard permit conditions and attachments.

On June 29, 2026, a 120-day public comment period will open for Revision 9A (Rev. 9A) and continue to Oct. 27, 2026. We encourage the public to review and submit comments.
