Approval and Promulgation of Implementation Plans; Tennessee: Approval of Source Specific Revisions to the Nonregulatory Portion of the Tennessee SIP Regarding Emission Limits for Particulate Matter and Volatile Organic Compounds

The EPA is approving two requests by the Tennessee Department of Air Pollution Control (TDAPC) to incorporate revised permits for eight facilities into the Tennessee State Implementation Plan (SIP). All of the permits affected by this action were previously approved into the SIP to meet various Clean Air Act (CAA) and regulatory requirements. EPA is approving an April 9, 1997, submittal from TDAPC that amends permits for the Soda Recovery Furnace and the Smelt Tank at Willamette Industries Inc., Kingsport, to establish revised particulate matter (PM) emission limits for these units. The revised emission limits will have a net positive impact on ambient air quality. An April 14, 1997, submittal from the Chattanooga-Hamilton County Air Pollution Control Bureau (CHCAPCB), through TDAPC, revises the permits as amended by agreed order for seven miscellaneous metal parts coaters located in Hamilton County to qualify them as a synthetic minor sources. Based on supplemental information received from CHCAPCB, EPA has concluded that one of these seven facilities is now a new source and thus need not be included in this approval action. EPA is approving the revised permits for the remaining six facilities into the SIP.
