EMCON Announces Innovative Value-Added Client Service Capability.

SAN MATEO, Calif.--(BUSINESS WIRE)--Nov. 29, 1995--A computer program developed by EMCON (NASDAQ:MCON) to alert clients about exceedances of critical threshold values and calculate risks at minimal cost has proven popular with EMCON clients.

The program, called TRIGGERS, is designed to easily determine if a chemical in soil, water, or air "triggers" a regulatory response for the complex maze of state and federal standards. This program is especially attractive to national companies who are cutting back on staff and must deal with regulatory analysis in a large number of states where "in-house" expertise on all state regulations is burdensome.

EMCON has signed agreements within the past month to provide TRIGGERS access with several national clients who chose the service because of the low cost and the up-to-date data the program provides.

The current version contains approximately 10,000 promulgated values including drinking water standards, groundwater protection standards, RCRA action levels, CERCLA preliminary remediation goals, National Ambient Air Quality Standards, OSHA permissible exposure limits, EPA hazardous waste numbers, treatment standards, and emergency planning and notification values.

EMCON is a nationally recognized consulting firm providing services in environmental engineering, waste management, air and water quality management and construction. Established in 1971, EMCON offers its environmental services from over 40 offices nationwide to private and public sector clients in the United States and abroad.
