ATG Completes Start-Up Phase of New Thermal Processing System; GASVIT System Will Enable Thermal Processing of Low-Level Mixed Waste.

Business Editors

FREMONT, Calif.--(BUSINESS WIRE)--Oct. 5, 2000

ATG Inc. (Nasdaq:ATGC), a leading provider of low-level radioactive and low-level mixed waste treatment services, today announced that it has successfully completed the initial start-up phase of its proprietary GASVIT(TM) thermal processing system.

GASVIT(TM) is a gasification/vitrification technology installed at the Company's Low Level Mixed Waste ("LLMW") facility in Richland, WA. The final step of the start-up phase, executed by the Company on September 28, 2000, included a five-day thermal heat-up operation resulting in the production of molten glass in the GASVIT(TM) melter.

The next phase is the pre-operation demonstration of the GASVIT(TM) system. Surrogate material will be systematically processed to test the system as an integrated unit. Similar to the initial start-up of ATG's SAFGLAS(TM) system, employees will operate the entire GASVIT(TM) system and process non-radioactive material during the demonstration period.

Previously, it took ATG approximately 60 days to complete the pre-commercial demonstration of its SAFGLAS(TM) system, and the Company currently anticipates a similar time frame for the GASVIT(TM) system.

ATG's LLMW facility consists of both thermal and non-thermal treatment processes. The Company commenced non-thermal LLMW processing in December 1999. The facility has a non-thermal capacity of 8,000 metric tons per year, and a thermal capacity of 1,250 metric tons per year under its present permit. ATG presently has multi-year contracts to treat LLMW with U.S. Department of Energy facilities in Washington, Tennessee, New York and California.

"It has been a full five years since we started work on the LLMW facility," said Doreen Chiu, president and chief executive officer ATG. "Our achievements in both thermal and non-thermal LLMW processing will enable us to serve the sizable DOE and commercial LLMW market, and position us to play a key role in the important environmental clean-up and LLMW treatment business," added Ms. Chiu.
