Public Comment Period on a Class 2 Permit Modification to the Hanford Dangerous Waste Permit, “Liquid Effluent Retention Facility and 200 Area Effluent Treatment Facility” Chapter

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 and 200 Area Effluent Treatment Facility” chapter. This proposed permit modification is necessary to add an Acetonitrile Distillate Loadout Facility, acetonitrile distillate tote storage, acetonitrile distillate storage tanks, and brine storage tanks to the 200 Area Effluent Treatment Facility (ETF). These new dangerous-waste management units are necessary to support waste management operations resulting from the receipt of liquid effluent from Hanford’s Waste Treatment and Immobilization Plant.

The Liquid Effluent Retention Facility and ETF are mixed-waste treatment and storage units for treating liquid effluents from operating Hanford cleanup facilities. These facilities will process liquid waste from the Waste Treatment and Immobilization Plant in support of Hanford’s Direct-Feed Low-Activity Waste Program for treating tank waste.

The comment period will run from April 6 through June 4, 2022. A virtual public meeting will be held on May 10, 2022, at 5:30 p.m. PT. To participate via Microsoft Teams, please follow the instructions below:
