## Abstract

EPA is approving an alternative volatile organic compounds (VOC) control device for Serigraph, Inc. (Serigraph) as a revision to the Wisconsin State Implementation Plan (SIP). On May 18, 2005, the Wisconsin Department of Natural Resources submitted a request to revise the Wisconsin SIP. The revision approves Serigraph's use of a biofilter to control VOC emissions from its printing facility in Washington County, Wisconsin. The biofilter will achieve VOC emission reductions at or beyond the level of the control methods listed in the SIP. Serigraph has designed one of its plants as a permanent total enclosure (PTE), which captures all VOC emissions and routes them to the biofilter. There are no fugitive emissions from the plant. This control system will reliably control emissions at or below the level of Federally mandated emission limits.
