Perma-Fix Awarded a $23 Million Contract by Fluor Hanford for Thermal Treatment of Mixed Low-Level Waste

OAK RIDGE, Tenn., Oct 26, 2004 /PRNewswire-FirstCall via COMTEX/ -- Perma-Fix Environmental Services, Inc. (Nasdaq: PESI; BSE: PESI) (Germany: PES.BE) has been awarded a multi-year contract valued at approximately $23 million for the treatment of mixed low-level wastes generated at the Department of Energy's (DOE) Hanford Site.

The Hanford Site, located in southeastern Washington State and covering 586 square miles, was a plutonium production complex that played a pivotal role in the nation's defense for more than 40 years. Today, under the direction of DOE, the Hanford Site is engaged in the largest environmental clean-up project in the world. Fluor Hanford, a prime contractor supporting DOE's cleanup mission at Hanford, has awarded this contract to Perma-Fix to provide specialized thermal treatment for a variety of mixed low-level radioactive wastes generated at Hanford. Some of these mixed wastes are currently in storage awaiting treatment while additional wastes will be generated through ongoing site operations.

Perma-Fix will utilize the capabilities of its Nuclear Segment's three mixed waste treatment facilities to accomplish this work for the term of the three-year contract. The variety and complexity of these mixed wastes require specialized technical expertise and operational capacity that will be provided using the synergistic capabilities of each of our facilities. Dr. Louis F. Centofanti, Perma-Fix chairman and chief executive officer, stated, "The award of this contract is very gratifying to Perma-Fix in that Fluor Hanford continues to be confident of our capability to address some of the most challenging waste streams that result from the Department of Energy's cleanup efforts. We have performed similar work for Fluor Hanford, and we will continue to support DOE and its contractors with their goals to clean up the legacy of the Cold War."
