Environmental Performance Demonstration Testing Class 2 permit modification

The U.S. Department of Energy is holding a 60-day public comment period and meeting on a proposed Class 2 permit modification to the Hanford Dangerous Waste Permit. If approved, the modification would allow Bechtel National Inc. to conduct environmental performance demonstration tests at the Waste Treatment and Immobilization Plant. A temporary authorization request was also submitted with this modification to allow testing in a single melter configuration. The temporary authorization allows the testing to be conducted in tandem with the comment period.
