Environmental Protection | Projects

Washington Closure Hanford’s Environmental Protection organization helps protect workers and the environment by ensuring cleanup work is performed within applicable state and federal environmental laws and guidelines.

The Environmental Protection organization provides subject matter expertise in environmental regulatory compliance; waste management shipping and transportation; natural, cultural, and historical compliance and mitigation; risk assessment and site closure and close-out verification and data management.

For resolution of significant environmental compliance issues, Environmental Protection serves as the principle interface between Washington Closure and U.S. Department of Energy’s Richland Operations Office, state and federal regulators, other Hanford contractors, Native American tribes and other important stakeholders.

Work on the River Corridor Closure Project is governed by the Washington Closure Hanford Environmental Protection and Compliance Policy.

Mission Completion

Environmental Protection Mission Completion (MC) (formerly the End State and Final Closure Project) is chartered to plan, execute, and control work resulting in (1) a determination that no further action is needed to protect human health and the environment and (2) obtaining a proposed “finding of suitability to transfer ” and to support transition of transfer Hanford’s River Corridor to long-term stewardship. The Integration and Assessment, Long-Term Stewardship, and Sample Design and Cleanup Verification tasks within the MC project are structured to fulfill these goals.

Ongoing, open communication among the many parties interested in Hanford Site cleanup continue as the work progresses under these tasks. This website has been created to provide an information repository and includes links to documents available for review and comment, administrative information, and dates for public involvement opportunities.
