The Environmental Protection Agency (EPA) is taking final action to approve a state plan submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC) on May 12, 2017, and supplemented on February 9, 2018, for implementing and enforcing the Emissions Guidelines (EG) applicable to existing Commercial and Industrial Solid Waste Incineration (CISWI) units. The State plan provides for implementation and enforcement of the EG, as finalized by EPA on June 23, 2016, applicable to existing CISWI units for which construction commenced on or before June 4, 2010, or for which modification or reconstruction commenced after June 4, 2010, but no later than August 7, 2013. The State plan establishes emission limits, monitoring, operating, recordkeeping, and reporting requirements for affected CISWI units. Since all the CISWI units in the State are located at the Eastman Chemical Company in Kingsport, Tennessee, the State has issued the facility an operating permit, the terms of which are the relevant provisions of the EG, and has submitted the permit as part of its State plan.
