Section 1200-03-18-.12 - CAN COATING(1) Applicability of this rule is as follows:(a) This rule applies to any can coating line used to apply the following coatings: sheet base coat, exterior base coat, interior body spray coat, overvarnish, side seam spray coat, exterior end coat, and end sealing compound coat.(b) The emission limits of this rule do not apply to can coating lines within any facility: 1. In Davidson, Rutherford, Sumner, Williamson, or Wilson County whose actual emissions without control devices from all can coating lines 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 can coating lines 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 can coating lines 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 can coating lines within the facility are less than 100 tons of volatile organic compounds (VOC's) per year.(c) An owner or operator of a facility which achieves exemption by having emissions below the 6.8 kg (15 lb)-per-day applicability threshold in Part (b)1 of this paragraph shall comply with the certification, recordkeeping, and reporting requirements of Paragraph .03(2) of this chapter.(2) For the purpose of this rule, the following definitions apply: (a) "Can" means any cylindrical single walled container, with or without a top, cover, spout, and/or handle, that is manufactured from metal sheets thinner than 29 gauge (0.0141 inches [in]) and into which solid or liquid materials are packaged.(b) "Can coating line" means a coating line in which any coating is applied onto the surface of cans or can components.(c) "End sealing compound coat" means a compound applied onto can ends that functions as a gasket when the end is assembled onto the can.(d) "Exterior base coat" means a coating applied to the exterior of a two-piece can body to provide protection to the metal or to provide background for any lithographic or printing operation.(e) "Interior body spray coat" means a coating applied to the interior of the can body to provide a protective film between the product and the can.(f) "Overvarnish" means a coating applied directly over a design coating or directly over ink to reduce the coefficient of friction, to provide gloss, and to protect the finish against abrasion and corrosion.(g) "Sheet basecoat" means a coating applied to metal in sheet form to serve as either the exterior or interior of two-piece or three-piece can bodies or can ends.(h) "Side-seam spray coat" means a coating applies to the seam of a three-piece can.(i) "Three-piece can" means a can that is made by rolling a rectangular sheet of metal into a cylinder that is soldered, welded, or cemented at the seam and attaching two ends.(j) "Two-piece can" means a can whose body and one end are formed from a shallow cup and to which the other end is later attached.(k) "Two-piece can exterior end coat" means a coating applied by roller coating or spraying to the exterior end of a two-piece can to provide protection to the metal.(3) Standards as follow apply: (a) No owner or operator of a can coating line subject to this rule shall cause or allow the application of any coating on that line with VOC content, as applied, that exceeds the following limits: | kg/L | a lb/gal |
| 1. Sheet basecoat and sheet overvarnish | 0.34 | 2.8 |
| 2. Exterior basecoat and overvarnish (two-piece can) | 0.34 | 2.8 |
| 3. Interior body spray coat | 0.51 | 4.2 |
| 4. Two-piece can exterior end coat | 0.51 | 4.2 |
| 5. Side seam spray coat | 0.66 | 5.5 |
| 6. End sealing compound coat | 0.44 | 3.7 |
a VOC content values are expressed in units of mass of VOC (kg, lb) per volume of coating (liter [L], gallon [gal]), excluding water and/or exempt compounds, as applied.
(b) As an alternative to compliance with the emission limits in Subparagraph (a) of this paragraph, an owner or operator of a can coating line may comply with the requirements of this rule by meeting the requirements of Paragraph (4) or (5) of this rule.(4) No owner or operator of a can coating line subject to this rule shall apply coatings on that line, during any day, whose weighted average VOC content exceeds the emission limits in Subparagraph (3)(a) of this rule.(5) Control device requirements as follow apply:(a) An owner or operator of a can coating line subject to this rule may comply with Subparagraph (3)(b) of this rule by:1. Installing and operating a capture system and a control device on that line;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 can coating line subject to this rule shall ensure that: 1. A capture system and control device are operated at all times that the line is in operation, 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.
