The proposed cleanup plan to address contamination in groundwater and remaining waste sites presents six alternatives for remedial action and identifies a preferred alternative. The alternatives consider several levels of soil removal and groundwater remedies that range from monitored natural attenuation to pump-and-treat methods. The preferred remedial alternative includes restrictions on access, on disturbing soils and on use of groundwater.
Proposed Class 2 permit modification for the Liquid Effluent Retention Facility and 200 Area Effluent Treatment Facility
Sept. 16, 2019 - Nov. 15, 2019
The U.S. Department of Energy (Energy) held a 60-day public comment period on a proposed modification to the Hanford Dangerous Waste Permit.

The improvements include adding a secondary waste load-out system inside ETF and adding a filter sump tank to the existing load-in station. This requires modification to the permit conditions and applicable addenda. Modifications to the addenda include revised information on the LERF and the 200 Area ETF boundary, the waste analysis plan, facility improvements, container management, leak detection, closure and inspection requirements.

Low Activity Waste Pretreatment System (LAWPS) permit modification
May 1, 2019 - June 30, 2019
The Department of Energy (DOE) Office of River Protection held a 60-day public comment period to support a Class 3 modification to the Hanford Dangerous Waste Permit. This modification requested the approval from Ecology to add a new operating unit for the Low Activity Waste Pretreatment System (LAWPS). This operating unit will pretreat (remove cesium and filter out solid particles) double-shell tank waste for subsequent vitrification in the Hanford Tank Waste Treatment and Immobilization Plant Low-activity Waste (LAW) facility.
The planned cesium removal system would be deployed in phases. Phase One would employ a Tank-Side Cesium Removal (TSCR) unit. Phase Two would either use a permanent cesium removal capability, LAWPS facility or an additional TSCR unit to support full operation of the LAW facility. This proposed modification will cover construction activities and operations needed to support the Phase One portion of the project.
