FREMONT, Calif.--(BUSINESS WIRE)--May 16, 2000

ATG Inc. (Nasdaq:ATGC), a leading provider of low-level radioactive and low-level mixed waste treatment services, today announced that it has been awarded a multiple-year low-level radioactive waste processing contract from Flour Hanford Inc.

ATG estimates the potential total value of the contract to be approximately $3 million over the two-year base contract period and the two one-year option periods.

Flour is the U.S. Department of Energy's (DOE) Management Integration Contractor for the Hanford Reservation near Richland, Wash. The contract, which started on May 9, 2000, is intended to improve the efficiency of low-level waste disposal at Hanford in a manner that preserves valuable land resources. The work will be performed at ATG's Richland, Wash., facilities.

"DOE Hanford is one of ATG's long-time valued customers," said Doreen Chiu, president and chief executive officer of ATG. "This contract brings the value of current DOE Hanford contracts, which includes on-going mixed waste contracts, to over $33 million. We are very pleased to have the opportunity to continue to serve the DOE complex."

The low-level waste to be processed includes paper, plastic, wood, metal, glass, asbestos and general debris resulting from the decontamination and decommissioning of DOE's nuclear facilities at Hanford.

In performing the work, ATG plans to employ predominantly non-thermal techniques that will reduce the volume of the low-level wastes. ATG will package the processed materials in a manner that fully complies with the Hanford waste acceptance criteria. The processed materials will be returned to DOE for ultimate placement in disposal trenches on the Hanford Reservation.
