BUGS Reactivates GaeaCare Interest for Disaster Response; SSWM Expertise and New Technology May Provide Applications for Natural Disasters Such as Katrina.

CARLSBAD, Calif. -- U.S. Microbics, Inc. (OTCBB:BUGS) said today that it is discussing the possibility of reactivating its interest in the GaeaCare technology it helped pioneer in 2002 with Sub-Surface Waste Management, Inc. (OTCBB:SSWM), a ten percent shareholder of GaeaCare, and other technology partners for on-site facility vigilance and response for sudden and catastrophic toxic and hazardous material releases to both air and water resources. The company has been dormant for several years, but with the recent purchase by Winsted Holdings, Inc. there may be another opportunity to bring this vital technology to market for natural disasters such as the current wave of hurricanes slamming the U.S. borderline.

GaeaCare was originally planning to commence operations as a worldwide provider of 24/7 on-site facility vigilance and response for sudden and catastrophic toxic and hazardous material releases to both air and water resources. The protected facilities would be able to immediately alert emergency agencies to sudden airborne and/or surface toxic chemical releases and simultaneously begin to reduce potentially deadly effects of any gaseous cloud using naturally occurring microbial blends sprayed with water and fire retardants to precipitate toxics from the air and/or water using an enhanced proprietary formulation of nature's biological process to covert toxic materials into harmless CO2 and water.

"Cutting edge environmental engineering applications with biotechnology solutions are the hallmark of the GaeaCare systems which can be applicable to petroleum & petrochemical refiners, bulk storage tank and pipeline operators, mining, manufacturing, power & munitions plants, government environmental agencies, military installations and Homeland Defense Security Agencies," said Bruce S. Beattie, President of SSWM. "SSWM can provide both the environmental engineering and biotechnology product solutions to enable GaeaCare to capture emissions either airborne or surface released and immediately apply proprietary, all natural, non-genetically engineered microbial blends that accelerate the process of turning harmful toxics into simple CO2 and water. SSWM environmental biotechnology solutions are directly applicable and eagerly being sought by the international market where cost-effective and reasonably rapid treatment solutions are in great demand in response to both World Trade Organization and ISO conventions for strict environmental compliance as a requirement for access to consumer markets."

Robert Brehm, BUGS CEO commented, "We welcome the new owners and their renewed interest in GaeaCare and fully support their efforts to bring this valuable disaster response technology to market with our technical support."
