Event: Public Comment Period for a Proposed Class 2 Permit Modification for the Supplemental Organic-Waste Treatment Facility at the Effluent Treatment Facility
Category: Comment Period / Feedback Opportunity
Event Date: 06/23/2021 to 08/22/2021

The U.S. Department of Energy is holding a 60-day public comment period on a proposed Class 2 permit modification to the Hanford Dangerous Waste Permit, Liquid Effluent Retention Facility (LERF) and 200 Area Effluent Treatment Facility (ETF) chapter. This proposed permit modification is required to install a supplemental organic-waste treatment system at ETF.

ETF is located near the center of the Hanford Site and will process liquid waste from the Waste Treatment and Immobilization Plant in support of the Direct-Feed Low-Activity Waste approach to treating tank waste. The new organic-waste treatment system will supplement other treatment systems at ETF to ensure discharges of treated liquids from the facility meet requirements for disposal at the State Approved Land Disposal Site at Hanford.

The comment period will run from June 23 through Aug. 22. A virtual public meeting will be held July 22, 2021, at 5:30 p.m. PT. To participate, please follow the instructions below:
