Perma-Fix Receives First Shipments of Radioactive PCBs from the U.S. Department of Energy

ATLANTA, April 22 /PRNewswire-FirstCall/ -- Perma-Fix Environmental Services, Inc. (Nasdaq: PESI) today announced the receipt of 940 gallons of radioactive Polychlorinated Biphenyls (PCB) liquids from the U.S. Department of Energy's (DOE) Paducah Gaseous Diffusion Plant located in Kevil, KY. This waste marks the first shipment to Perma-Fix of radioactive PCBs from the DOE under the Company's new authorization issued by U.S. Environmental Protection Agency (EPA) Region 4. This authorization allows the Company's Diversified Scientific Services, Inc. (DSSI) facility, located in Kingston, Tennessee, to commercially store and dispose of radioactive PCBs through thermal treatment. DOE's prime contractor at Paducah is Paducah Remediation Services, LLC, which is responsible for the management and shipment of these wastes to DSSI.

The company also announced its second shipment from CH2M HILL Plateau Remediation Company (CHPRC), the prime contractor for the DOE at the Hanford Site in Washington State. The CHRPC shipment consisted of 1,500 gallons of radioactive PCB wastes.

Perma-Fix's DSSI facility uses an EPA-authorized waste fuel boiler unit for the thermal destruction of radioactive and mixed (radioactive and hazardous) liquids and semi-solid wastes. In 2004, Perma-Fix DSSI began the permitting process to add TSCA-regulated wastes, namely radioactive PCBs, to its authorization in order to meet the demand for the treatment of government and commercially generated radioactive PCB wastes.

Currently, there are no other authorized, commercial facilities treating radioactive PCB wastes. The DOE operates a TSCA incinerator authorized to treat only DOE generated wastes, which is scheduled to begin closure activities in 2009. The DSSI authorization provides the DOE with an alternative option for disposing of radioactive PCB wastes, and it provides commercial operators an outlet to dispose of commercially generated radioactive PCBs. Additional PCB wastes from DOE and commercial generators are also scheduled for receipt this month.

Dr. Louis F. Centofanti, Chairman and Chief Executive Officer, stated, "Perma-Fix is excited about providing the DOE and commercial radioactive PCB waste generators with the first capacity for the safe destruction of radioactive PCB wastes. We appreciate the support that PRS Paducah and CHPRC have shown us by being the first into our facility for treatment. This capability will be important as the DOE works on footprint reduction, as a requirement of the American Recovery and Reinvestment Act (ARRA) monies that it has been allocated, and which Congress passed in February 2009. For commercial generators, this capacity will allow disposition of radioactive PCB wastes that have been in storage for years awaiting a disposal pathway."
