Perma-Fix Comments on Recently Published Department of Energy Notice

ATLANTA, Feb. 06, 2023 (GLOBE NEWSWIRE) -- Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the “Company”) today announced that the U.S. Department of Energy (DOE) has recently published an amendment to the 2013 Record of Decision (ROD) for the Final Tank Closure and Waste Management Environmental Impact Statement for the Hanford Site, Richland, Washington (DOE/EIS-0391, December 2012) (TC&WM EIS).

In accordance with DOE implementing procedures for the National Environmental Policy Act (NEPA), DOE prepared a supplement analysis (DOE/EIS-0391-SA-03; SA), which evaluated DOE's proposal to transport and treat certain solid and liquid secondary wastes at licensed and permitted commercial treatment facilities off the Hanford Site. DOE also proposes to potentially dispose of some of these secondary wastes (after treatment) offsite at a licensed and permitted commercial disposal facility.

This action would be implemented on an interim basis until such time as an enhanced onsite treatment capability is available for Direct-Feed Low-Activity Waste (DFLAW) operations (estimated to be approximately 10 years). This amended ROD addresses the differences in the planned management of secondary wastes from that addressed by the 2013 TC&WM EIS ROD document, and specifically addresses the anticipated role that Perma-Fix could support in the closure plan for Hanford over the next decade. A link to the Federal Register notice is available at:

Mark Duff, President and CEO of the Company, commented, “This announcement regarding the ROD amendment recognizes the unique value that Perma-Fix can provide the Department at our Perma-Fix Northwest facility in Richland, WA, and our Diversified Scientific Services Inc. (DSSI) facility in Kingston, TN, to deploy leading-edge treatment capabilities for some of the more complicated waste streams to be generated at Hanford during a 10-year period. The volumes and waste types defined in this amendment reflect our core offering and represents a significant opportunity for growth in our backlog. We remain committed to exceeding expectations by providing safe, commercial, waste processing to support the Hanford closure mission.”
