Perma-Fix Facility Certified for Disposal at Nevada Test Site

OAK RIDGE, Tenn., April 26 /PRNewswire-FirstCall/ -- Perma-Fix Environmental Services, Inc. (Nasdaq: PESI) (BSE: PESI) (Germany: PES.BE) announced today that its wholly owned subsidiary East Tennessee Materials & Energy Corp. (M&EC) has been approved to dispose of low-level and mixed waste at the Nevada Test Site (NTS) of the U.S. Department of Energy (DOE) National Nuclear Security Administration.

This NTS approval, the first to be granted for both types of waste to a commercial treatment provider, is a key element in the new Perma-Fix/M&EC service offering for higher activity and other specialty waste streams. The NTS disposal facility, which accepts only DOE-owned low-level and mixed low- level waste, is unique among commercial and DOE disposal sites in its ability to dispose of these specialty waste streams.

Dr. Louis F. Centofanti, Perma-Fix chairman and chief executive officer, said, "We are pleased to be the first commercial treatment provider to be granted the permission to use the services of the Nevada Test Site. This certification, coupled with NTS's recently acquired permission to dispose of mixed low-level wastes and the expansion of the Perma-Fix/M&EC facility, provides a great resource to DOE in its efforts to perform clean-up projects across the U.S."

Perma-Fix/M&EC has been developing this new service offering for more than two years, said Centofanti. It will expand the M&EC capacity and capability to process waste streams that are difficult because of their radiological and chemical contamination. The Perma-Fix/M&EC facility, located at the Heritage Center, formerly known as the DOE K-25 plant, was specifically designed and constructed to treat DOE-generated wastes. It already offered the largest variety of mixed waste treatment processes in the U.S. This new service offering will be in addition to the Company's current mixed waste treatment activities.

Perma-Fix Environmental Services, Inc. is a national environmental services company, providing unique mixed waste and industrial waste management services. The Company has increased its focus on the nuclear services segment, which provides radioactive and mixed waste treatment services to hospitals, research laboratories and institutions, numerous federal agencies including DOE and the U.S. Department of Defense and nuclear utilities. The industrial services segment provides hazardous and non-hazardous waste treatment services for a diverse group of customers including Fortune 500 companies, numerous federal, state and local agencies and thousands of smaller clients. The Company operates eight major waste treatment facilities across the country.
