You can always weigh in on cleanup anytime by contacting your elected officials and sharing your input with others by commenting on news stories and writing letters to the editor. You can also ask questions, share your input,  and express your concerns with the Tri-Party Agencies by emailing



Meetings are held throughout the year for educational outreach purposes, giving updates and soliciting public input on the Hanford remediation efforts. By attending meetings, you have the opportunity to ask questions, increase your understanding of the issues and weigh in on what kind of future you want for the Hanford site. 



Take the lead in educating others about Hanford cleanup. Host a movie night or HC presentation in your home, on your campus, or in a community space. We at HC are eager to share information and cultivate an informed public in the PNW to weigh in on Hanford's remediation. Email to get started.

tips on writing an effective COmment

  1. Stick to one neatly written or typed page.
  2.  In a short first paragraph, state your purpose. Use the rest of the letter to explain your position. Be factual and polite. 
  3. Stick to one subject or issue per comment.
  4. If a document is the subject, cite it by name and number - if applicable.
  5. Include your name and address. The Tri-Party Agencies respond directly to each comment individually.
