Tri-S Environmental performed a site inspection to review operations at a large semi-conductor manufacturing facility which produced silicon wafers for flash memory drives. The purpose of the Site inspection and records review was to develop an overview of environmental compliance at the facility. Confirmation of the site layout, inspection of hazardous materials/waste management practices and observations of general operating and housekeeping practices were the central focus. Tri-S Environmental also conducted a historic land investigation for the Site to determine potential environmental risks posed by historic on-site or offsite facilities. The review also included the analysis of three wastewater systems, two water treatment plants and an extensive air emissions treatment system at the facility which was the largest flash memory wafer plant in the world at the time.
