Section 1200-03-18-.13 - COIL COATING(1) Applicability of this rule is as follows:(a) This rule applies to any coil coating operation.(b) This rule does not apply to any coil coating operation within a facility:1. In Davidson, Rutherford, Sumner, Williamson, or Wilson County whose actual emissions without control devices from all coil coating operations within the facility are less than 6.8 kilograms (kg) (15 pounds [lb]) of volatile organic compounds (VOC's) per day or whose maximum theoretical emissions from all coil coating operations within the facility are less than 10 tons of volatile organic compounds (VOC's) per year;2. In Hamilton or Shelby County whose potential VOC emissions from all coil coating operations within the facility are less than 25 tons of volatile organic compounds (VOC's) per year; or3. In any other county whose potential VOC emissions from all coil coating operations within the facility are less than 100 tons of volatile organic compounds (VOC's) per year.(2) For the purpose of this rule, the following definitions apply: (a) "Coil" means any continuous metal strip with thickness of 0.15 millimeter (mm) (0.006 inch [in]) or more that is packaged in a roll or coil.(b) "Coil coating line" means a web coating line where coating is applied to coil.(c) "Coil coating operation" means a coating application station and its associated flashoff area, drying area, and/or drying oven wherein coating is applied and dried or cured on a coil coating line. A coil coating line may include more than one coil coating operation.(3) Standards as follow apply:(a) No owner or operator of a coil operation subject to this rule shall cause or allow the application of any coating on that operation with VOC content in excess of 0.31 kilograms per liter (kg/L) (2.6 pounds per gallon [lb/gal]) of coating, excluding water and/or exempt compounds, as applied.(b) As an alternative to compliance with the emission limit in Subparagraph (a) of this paragraph, an owner or operator of a coil coating operation may meet the requirements of Paragraph (4) or (5) of this rule.(4) No owner or operator of a coil coating operation subject to this rule shall apply coatings on that operation, during any day, whose weighted average VOC content exceeds the emission limit in Subparagraph (3)(a) of this rule.(5) Control device requirements as follow apply:(a) An owner or operator of a coil coating operation subject to this rule may comply with this rule by: 1. Installing and operating a capture system and a control device on that operation;2. Determining for each day the overall emission reduction efficiency needed to demonstrate compliance. The overall emission reduction needed is the lesser of the value calculated according to the procedure in this chapter or 95 percent; and3. Demonstrating each day that the overall emission reduction efficiency achieved is greater than or equal to the overall emission reduction efficiency required.(b) An owner or operator of a coil coating operation subject to this rule shall ensure that: 1. A capture system and control device are operated at all times the coating operation is in use, and the owner or operator demonstrates compliance with this rule through the applicable coating analysis and capture system and control device efficiency test methods specified in this chapter; and2. The control device is equipped with the applicable monitoring equipment specified in this chapter, and the monitoring equipment is installed, calibrated, operated, and maintained according to the vendor's specifications at all times the control device is in use.Tenn.
