EPA v. KOPPERS INC - ACO

Case summary

EPA identified emission limit exceedances for VOCs and napthalene, based on the results of performance testing. Koppers also failed to obtain an appropriate operating permit for the Galesburg facility. A CAFO will be issued concurrently with the ACO and includes a penalty of $172,314. This ACO requires Koppers Inc. to obtain a federally enforceable state operating permit from Illinois EPA that requires the continuous operation and monitoring of a scrubber system controlling emissions at the Galesburg facility. The facility was not required to operate the scrubber system and was unable to provide records to confirm its regular operation. Continuous operation of the scrubber system is estimated to reduce VOC emissions by 95 tons per year and naphthalene emissions by 19 tons per year.
