WEST LAKE VILLAGE, CA, March 22, 1999 -- Marvin Mears, president and chief executive officer of Environmental Products & Technologies Corporation, announced today that EPTC will be among the featured speakers at the Livestock Waste Management Seminar to be held on March 31, 1999, co-sponsored by Edison AgTAC and the EPRI Agricultural Technology Alliance at the Southern California Edison AgTAC facility in Tulare, California. Representatives from the Tulare County Board of Supervisors, the Regional Water Quality Control Board, the U.S. Department of Agriculture's Natural Resources Conservation Service and the U.S. Environmental Protection Agency are also featured on the seminar agenda.

Over 100 California dairy farm owners are expected to attend the Livestock Waste Management Seminar. The Tulare area of California's Central Valley has become one of the fastest growing dairy farming areas in the country, and the rapid growth of the area's large, highly concentrated, livestock operations has already had a notable impact on the region's environment.

The Department of Agriculture and the U.S. Environmental Protection Agency jointly created the Unified National Strategy for Animal Feeding Operations, aimed at better management of the nearly 1.4 billion tons of manure created each year by the livestock raising industry. The strategy identifies approximately 450,000 animal raising and feeding operations and mandates compliance by the 20,000 largest operations within the next three years. Seminars such as the one being held on March 31 are a major source of information that allows farmers to stay ahead of the legislative curve by identifying cost-effective solutions for their animal and waste management problems.

EPTC's Closed-loop Waste Management System is designed to solve the agricultural waste problems for farm operations, including those concentrated in California's Central Valley. EPTC's presentations will discuss the environmental and waste management benefits of the system, and the company's portable aerobic Bioreactor will be displayed.

"EPTC's participation in this seminar further validates our technology and dovetails with our concentrated marketing efforts in the region," said Mears. "The economy of Tulare County is closely tied to animal raising and represents a major market for EPTC systems and services," he added.

Environmental Products & Technologies Corporation is focused on solving environmental problems to optimize the productivity of farming and large livestock operations. EPTC's Closed-Loop Waste Management System separates animal or food wastes into solids and liquid, which are processed into a nutrient-rich soil amendment, agricultural water and energy generated from methane.
