BUGS Subsidiary Entering Final Negotiation Phase in Mexico Emergency Response Centers; SSWM/ETI Team Plans to Implement Two to Four Centers by the End of 2006.

CARLSBAD, Calif. -- Robert Brehm, CEO of U.S. Microbics, Inc. (OTCBB:BUGS)(BCN:615212), an innovative environmental products and services company, announced that its majority owned subsidiary, Sub-Surface Waste Management of Delaware, Inc., (OTCBB:SSWM), and its Mexico subsidiary company, Environmental Tec International, S.A. de C.V. (ETI), have entered the final negotiation phase to initially equip and staff and operate eleven Environmental Emergency Response Centers (ERC) in Veracruz. The Centers are being set up to address civil protection and exposure to toxic releases such as fuel and oil spills that occur periodically as well as during storm events such as hurricanes.

Brehm elaborated, "We have made significant progress in Mexico this year with new contracts from the electric utility and new cleanup projects in Puebla and Veracruz. We are now entering the final negotiation phase of establishing regional emergency response centers to protect citizens from environmental disasters. Not only are we providing environmental engineering services but we will also be enhancing the economic and social environment of Veracruz by establishing technical training and new jobs as the centers are implemented."

Brehm further commented, "SSWM and ETI are in final negotiations with Governor Herrera of Veracruz and his staff to formalize the financing schedule for the capital equipment to be ordered from SSWM for the centers, and to develop specific siting and implementation schedules for the eleven centers under the terms of an ETI five year operating agreement. ETI is also currently interviewing Mexico and USA subcontractors to determine resource capability and availability for the project which plans to implement two to four centers by the end of 2006.

Brehm continued, "The emergency response centers project is no small task for any company. SSWM/ETI has done an excellent job by bringing both the project and the financing to the table, providing business development services with key government officials and coordinating US and foreign subcontractors. We expect the ERC project and other projects under contract and pending in various states of Mexico will provide record-breaking revenue year in FY 2006 and 2007 and put us on solid financial ground for the foreseeable future!"
