Publication Summary

The Washington State Department of Ecology (Ecology) encouraged the public to comment on the removal of the 324 and 327 Buildings in the 300 Area of the Hanford Site from the Air Operating Permit (AOP) during a public comment period held March 20 through April 21, 2006. The emissions from these buildings will no longer be regulated by the AOP. The permit modification will remove requirements for monitoring and control of radioactive air emissions at the 324 and 327 Buildings by the AOP. Instead, the air emissions will be regulated by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in the new 300 Area removal action work plan. The work plan involves decontaminating and decommissioning the buildings, their stacks, and related facilities.
