Public comment periods

Want to share your input about cleanup efforts at Hanford? On this page, you can download documents, find out dates when you can submit your comments, and find out where to share your comments electronically through eComments.
Public comments are accepted over a 30, 45 or 60-day period. During that time you can share your input with us about specific changes in the permits we regulate. We review all comments and then issue a Response to Comments document, which will be posted online after the comment period has closed. View open and closed public comment periods.

Before submitting your comments, you can review or download relevant documents below, or you can review them in person at any of the Hanford Information Repositories.
