Draft Hanford Sitewide Permit renewal revision 9A

Ecology is holding a 120-day public comment period for the Hanford Dangerous Waste Permit (Sitewide Permit) draft renewal Revision 9A (Rev. 9A). The permittee is the U.S. Department of Energy. The Hanford Site is in southeastern Washington state.


Rev. 9A of the Sitewide Permit will cover 52 waste sites and facilities across Hanford. In this revision, Ecology addressed more than 5,000 comments from the public, Tribal Nations, and the permittee, received during the 2012 public comment period. This feedback led to extensive revisions to incorporate the comments and address deficiencies. Ecology’s priority is to issue a current permit that is protective of human health and the environment and enforceable under state and federal regulations.
