Title 7 Natural Resources and Environmental Control
1124 Control of Volatile Organic Compound Emissions
18.0 Vinyl Coating
01/11/1993
18.1 Applicability
18.1.1 The provisions of 18.0 of this regulation apply to any vinyl coating line.
18.1.2 The provisions of 18.0 of this regulation do not apply to:
18.1.2.1 Application of vinyl plastisol to fabric to form the substrate that is subsequently coated.
18.1.2.2 Any vinyl coating line within a facility whose actual emissions without control devices from all vinyl coating lines within the facility are less than 6.8 kilograms (kg) (15 pounds [lb]) of volatile organic compounds (VOCs) per day.
18.1.3 An owner or operator of a facility whose emissions are below the applicability threshold in 18.1.2.2 of this regulation shall comply with the certification, recordkeeping, and reporting requirements of 18.7.1 of this regulation.
18.1.4 Any facility that becomes or is currently subject to the provisions of 18.0 of this regulation by exceeding the applicability threshold in 18.1.2.2 of this regulation will remain subject to these provisions even if its emissions later fall below the applicability threshold.
18.1.5 Any facility that is currently subject to a state or federal rule promulgated pursuant to the Clean Air Act Amendments of 1977 by exceeding an applicability threshold is and will remain subject to these provisions, even if its throughput or emissions have fallen or later fall below the applicability threshold.
18.2 Definitions. As used in 18.0 of this regulation, all terms not defined herein shall have the meaning given them in the November 15, 1990 Clean Air Act Amendments (CAAA), or in 2.0 of this regulation.
“Vinyl coating line” means a web coating line where a decorative, functional, or protective coating is applied to a continuous web of vinyl or vinyl-coated fabric. Lines used for coating or printing on vinyl and coating or printing on urethane are considered vinyl coating lines.
18.3 Standards
18.3.1 No owner or operator of a vinyl coating line subject to 18.0 of this regulation shall cause or allow the application of any coating on that line with VOC content in excess of 0.45 kilograms per liter (kg/L) (3.8 pounds per gallon [lb/gal]) of coating, excluding water and exempt compounds, as applied.
18.3.2 As an alternative to compliance with the emission limit in 18.3.1 of this regulation, an owner or operator of a vinyl coating line subject to 18.0 of this regulation may meet the requirements of 18.4 or 18.5 of this regulation.
18.4 Daily-weighted average limitation. No owner or operator of a vinyl coating line subject to 18.0 of this regulation shall apply, during any day, coatings on any such line whose daily-weighted average VOC content, calculated in accordance with the procedure specified in Appendix C of this regulation, exceeds the emission limit in 18.3.1 of this regulation.
18.5 Control devices
18.5.1 An owner or operator of a vinyl coating line subject to 18.0 of this regulation may comply with 18.0 of this regulation by:
18.5.1.1 Installing and operating a capture system on that line.
18.5.1.2 Installing and operating a control device on that line.
18.5.1.3 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 3.0 of Appendix C of this regulation for that day or 95% .
18.5.1.4 Demonstrating each day that the overall emission reduction efficiency achieved for that day, as determined in 3.0 of Appendix D of this regulation, is greater than or equal to the overall emission reduction efficiency required for that day.
18.5.2 An owner or operator of a vinyl coating line subject to 18.0 of this regulation shall ensure that:
18.5.2.1 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 18.0 of this regulation through the applicable coating analysis and capture system and control device efficiency test methods specified in Appendix B, Appendix D and Appendix E of this regulation and in accordance with the capture efficiency test methods in Appendix D of this regulation.
18.5.2.2 The control device is equipped with the applicable monitoring equipment specified in 2.0 of Appendix D of this regulation, 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.
18.6 Test methods. The test methods found in Appendix A through Appendix D of this regulation shall be used to determine compliance with 18.0 of this regulation.
18.7 Recordkeeping and reporting
18.7.1 An owner or operator of a vinyl coating line that is exempt from the emission limitations in 18.3 of this regulation shall comply with the certification, recordkeeping, and reporting requirements in 4.2 of this regulation.
18.7.2 An owner or operator of a vinyl coating line subject to 18.0 of this regulation and complying with 18.3 of this regulation by the use of complying coatings shall comply with the certification, recordkeeping, and reporting requirements in 4.3 of this regulation.
18.7.3 An owner or operator of a vinyl coating line subject to 18.0 of this regulation and complying with 18.4 of this regulation by daily-weighted averaging shall comply with the certification, recordkeeping, and reporting requirements in 4.4 of this regulation.
18.7.4 An owner or operator of a vinyl coating line subject to 18.0 of this regulation and complying with 18.5 of this regulation by the use of control devices shall comply with the testing, reporting, and recordkeeping requirements in 4.5 of this regulation.
