Current through Register Vol. XLI, No. 50, December 13, 2024

Section 45-21-11 - Can Coating

11.1. Applicability.

11.1.1. This section 11. 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.

11.1.2. The emission limits of this section 11. do not apply to coating lines within any facility whose actual emissions without control devices from all can coating lines within the facility are less than 6.8 kilograms (kg) (15 pounds [lb]) volatile organic compound (VOC) per day. An owner or operator of a facility whose emissions are below this applicability threshold shall comply with the certification, recordkeeping, and reporting requirements of subdivision 11.7.1.

11.2. Definitions. -- As used in this section 11., all terms not defined herein shall have the meaning given them in section 2.

11.2.1. "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.

11.2.2. "Can coating line" means a coating line in which any coating is applied onto the surface of cans or can components.

11.2.3. "End sealing compound coat" means a compound applied onto can ends that functions as a gasket when the end is assembled onto the can.

11.2.4. "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.

11.2.5. "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.

11.2.6. "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.

11.2.7. "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.

11.2.8. "Side-seam spray coat" means a coating applied to the seam of a three-piece can.

11.2.9. "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.

11.2.10. "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.

11.2.11. "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.

11.3. Standards.

11.3.1. No owner or operator of a can coating line subject to this section 11. shall cause or allow the application of any coating on that line with VOC content, as applied, that exceeds the limits in Table 45-21A.

Table 45-21A

Emission Limit	kg/L	lb/gal^a
Sheet basecoat and sheet overvarnish	0.34	2.8
Exterior basecoat and overvarnish (two-piece can)	0.34	2.8
Interior body spray coat	0.51	4.2
Two-piece can exterior end coat	0.51	4.2
Side seam spray coat	0.66	5.5
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]), minus water and exempt compounds, as applied.

11.3.2. As an alternative to compliance with the emission limits in subdivision 11.3.1., an owner or operator of a can coating line may comply with the requirements of this section 11. by meeting the requirements of subsection 11.4. or subsection 11.5.

11.4. Daily-weighted average limitations. -- No owner or operator of a can coating line subject to this section 11. shall apply coatings on that line, during any day, whose daily-weighted average VOC content, calculated in accordance with the procedure specified in section 43., exceeds the emission limits in subdivision 11.3.1.

11.5. Control devices. -- An owner or operator of a can coating line subject to this section 11. shall comply with this section 11. by:

11.5.1. Installing and operating a capture system on that line;

11.5.2. Installing and operating a control device on that line;

11.5.3. Determining for each day the overall emission reduction efficiency needed to demonstrate compliance. The overall emission reduction needed for a day is the lesser of the value calculated according to the procedure in subsection 43.2. for that day or 95 percent; and

11.5.4. Demonstrating each day that the overall emission reduction efficiency achieved for that day, as determined in subsection 44.3., is greater than or equal to the overall emission reduction efficiency required for that day.

11.6. Test methods. -- The test methods found in sections 41. through 44. shall be used to determine compliance with this section 11.

11.7. Recordkeeping and reporting.

11.7.1. An owner or operator of a can coating line that is exempt from the emission limitations in subsection 11.3. shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.2.

11.7.2. An owner or operator of a can coating line subject to this section 11. and complying with subsection 11.3. by the use of complying coatings shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.3.

11.7.3. An owner or operator of a can coating line subject to this section 11. and complying with subsection 11.4. by daily-weighted averaging shall comply with the certification, recordkeeping, and reporting requirements in subsection 4.4.

11.7.4. An owner or operator of a can coating line subject to this section 11. and complying with subsection 11.5. by the use of control devices shall comply with the testing, reporting, and recordkeeping requirements in subsection 4.5.
