242-A Evaporator Class 3 - New Wall Penetrations

Ecology is holding a 45-day public comment period on a proposed modification to the Hanford Dangerous Waste Permit. This modification proposes allowing facility upgrades associated with the new waste transfer lines from the Double-Shell Tank (DST) System to the 242-A Evaporator. The original transfer lines failed pressure tests in 2018 and must be replaced. Specifically, this modification allows penetrating a wall to install the transfer lines and to perform modifications in the pump-room. These new transfer lines will allow the 242-A Evaporator to continue to treat DST waste, reducing DST waste volume, and allowing for continued Single-Shell Tank waste retrievals.
