Atlanta - June 14, 2007 — Perma-Fix Environmental Services, Inc. (Nasdaq: PESI; BSE: PESI; Germany: PES.BE), today announced that it has completed its acquisition of Nuvotec USA, Inc. (Nuvotec) and its wholly owned subsidiary, Pacific EcoSolutions, Inc. (PEcoS), for $11.2 million. PEcoS , based in Richland, Washington is a nuclear waste management company that treats both low level and mixed waste. In connection with the transaction, Perma-Fix issued $2.0 million in shares of Perma-Fix common stock and $2.5 million in debt instruments payable over a four year period to those Nuvotec shareholders that qualify as accredited investors, $2.3 million in cash to both non-accredited and accredited Nuvotec shareholders, and up to $4.4 million of cash earn-out to both non-accredited and accredited Nuvotec shareholders, which could vary dependent on meeting or exceeding certain future revenue thresholds over a four year period. Perma-Fix assumed $9.4 million of debt, plus the debts and obligations of PEcoS incurred in the ordinary course of PEcoS’ business. PEcoS’ facility is permitted to treat, store and process low level radioactive and mixed waste, and is located adjacent to the Department of Energy’s (DOE) Hanford site.

Dr. Louis F. Centofanti, Chairman and Chief Executive Officer, stated, “This important milestone is beneficial to Perma-Fix on many levels, as it increases our treatment capacity, expands our west coast presence, and secures PEcoS’ radioactive and hazardous waste permits and licenses. The PEcoS facility is located adjacent to the Hanford site and provides us access to treat some of the most complex nuclear waste streams in the nation. This is an important step in the development of our strategy to become a focused nuclear services company.”
