We're holding a 45-day public comment period addressing proposed modifications to the Hanford Dangerous Waste Permit for the Liquid Effluent Retention Facility (LERF) and the 200 Area Effluent Treatment Facility (ETF).
The permittees are U.S. Department of Energy and Washington River Protection Solutions. The LERF and 200 Area ETF facilities are located on the Hanford Site in southeastern Washington.
The modification proposal and supporting documents are on our Hanford public comment periods page.
This permit modification would allow the addition of a liquid retention basin to LERF.
The improvements include:
Modifications to the permit addenda include:
The Liquid Effluent Retention Facility and Effluent Treatment Facility, along with the Treated Effluent Disposal Facility, are all part of the Liquid Waste Processing Facility (LWPF). LWPF began construction in 1992 and became operational in 1995. The focus of the three facilities is to process a variety of Hanford Site waste containing high levels of chemical contamination and low levels of radioactive contamination.
ETF processes liquid waste, removing chemical and radioactive contaminants. LERF comprises of a series of retention basins made to store liquid waste until it can be processed at ETF.
