Waste Treatment Plant permit modification

Hanford Dangerous Waste Permit

Feb. 1, 2021 - March 17, 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 Waste Treatment and Immobilization Plant (WTP), located in Part III, Operating Unit Group 10.

The permittees are the U.S. Department of Energy, Office of River Protection, and Bechtel National, Inc. The Waste Treatment Plant (WTP) is located on the Hanford Site in Southeast Washington. 

Review and comment

The modification proposal and supporting documents are on our Hanford public comment periods page.

Proposed changes

This permit modification will update Chapter 11, Closure Plan. This Closure Plan identifies the actions necessary to close WTP permitted Dangerous Waste Management Units (DWMU). This includes the removal of dangerous and mixed waste and the decontamination of the permitted DWMU, ancillary equipment, and the associated secondary containment systems, if necessary. 

Submittal of this closure plan completes the requirements of III.10.C.8.b and Compliance Schedule items LAW-8 and EMF-8, located in Appendices 1.3 and 1.4 of the WTP Dangerous Waste Permit.

WTP background

The Hanford Waste Treatment & Immobilization Plant (WTP) is a waste management facility under construction just outside the eastern boundary of the 200 East Area of the Hanford site. It is regulated by the Hanford Sitewide Permit. When completed, the WTP will chemically separate, treat, and immobilize the majority of Hanford’s 56 million gallons of radioactive and chemical waste currently stored in 177 underground tanks using a process called vitrification.

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