Characterization of Dioxin Emissions from Sources that Use Ball Clays. Emission Test Report: Unimin Corporation, Gleason, TN. Final Report (Non-Confidential Version)

摘要

The EPA has determined that certain ball clay mineral deposits contain naturally-occurring dioxins. Ball clay processing facilities use low temperature dryers and heated milling systems to process ball clay prior to shipment to customers. The purpose of this emission test was to characterize dioxin (and furan) emissions from these dryers and milling systems. The test results will be used by EPA to determine the need for gathering any additional data related to thermal processing of ball clay.
