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 required by Liquid Effluent Retention Facility (LERF) and 200 Area Effluent Treatment Facility (ETF) Unit Specific Permit Conditions III.3.J.2, III.3.J.2.a and III.3.J.2.b. These conditions require leak-detection upgrades be made to the 4”-WTP-001-M17 waste transfer line. These permit conditions were added by a prior permit modification dated June 28, 2021.

The LERF and 200 Area ETF are mixed-waste treatment and storage units for treating liquid effluents from operating Hanford cleanup facilities. These facilities include the 242-A Evaporator and the Waste Treatment and Immobilization Plant’s Effluent Management Facility (when it becomes operational) to support treating tank waste using the Direct-Feed Low-Activity Waste approach.

The comment period runs from March 16 through May 14, 2022. A virtual public meeting will be held on April 12, 2022, at 5:30 p.m. PT. To participate via Microsoft Teams, please follow the instructions below:
