ENTEK

Air Toxics Health Risk Assessment Status

DEQ called in ENTEK International LLC to the Cleaner Air Oregon program on March 4, 2019. ENTEK is currently working on its Emissions Inventory which is the first step of the Cleaner Air Oregon health risk assessment process. DEQ created Cleaner Air Oregon facility web pages as part of an ongoing commitment to communities to be transparent and provide access to a facility’s health risk assessment information. Facility correspondence and deliverables are provided below.

About the Facility

ENTEK is a battery separator manufacturing facility that has operated in Lebanon since 1984. The facility manufactures lead acid separator material using a mix of oil and product specific additives such as polyethylene and silica. Lithium ion separator materials are manufactured using the same method without the use of silica. The mixture is extruded at an elevated temperature into desired shapes, and the oil is extracted from the microporous plastic product using a trichloroethylene bath.
