Section 1200-03-18-.44 - SURFACE COATING OF PLASTIC PARTS(1) APPLICABILITY. This rule applies as follows:(a) This rule applies to any plastic parts coating line within a facility located in Davidson, Rutherford, Sumner, Williamson or Wilson County whose potential VOC emissions from all plastic parts coating lines within the facility are greater than 25 tons of volatile organic compounds (VOC's) per year and coats plastic components for any of the following uses:1. Automotive or other transportation equipment including interior and/or exterior parts for automobiles, trucks, tractors, lawn mowers, and other mobile equipment;2. Business machines and office machines, including computers, copy machines, and typewriters;3. Medical equipment housing;4. Entertainment equipment housing;5. Miscellaneous plastic parts, including toys, musical equipment housing, sporting goods, outdoor signs, and architectural structures such as doors, floors, and window frames.(b) This rule does not apply to topcoating of automotive exterior panels, which must comply with Rule 1200-03-18-.11 of this chapter.(2) DEFINITIONS. For the purpose of this rule, the following definitions apply: (a) Basecoat/clear coat: a two step topcoat system in which a highly pigmented, often metallic, basecoat is followed by a clearcoat. It results in a finished with high-gloss characteristics and often used on automotive parts.(b) Clearcoat: a transparent coating usually applied over a colored, opaque coat to improve gloss and protection to the basecoat below.(c) Colorcoat: a coating that contains pigment and provides color to a part; may constitute the topcoat or serve as the base coat portion of the basecoat//clearcoat system.(d) Electromagnetic interference/radio frequency interference (EMI/RFI) coatings: coating used in plastic business machine housing to attenuate electromagnetic and radio frequency interference signals that would otherwise pass through the plastic housings. The EMI/RFI shielding substance used in coating include copper or nickel. Zinc-arc spraying, electroless plating, conductive plastics, metal inserts, and vacuum-metallizing and sputtering are other mean of EMI/RFI shielding.(e) Flexible coating: a coating with ability to withstand dimensional changes; flexible substrates utilizing flexible coatings include thermoplastic olefin (TPO), vinyl, acrylonitrile-butadiene (ABS) alloy, reaction injection molded (RIM) and thermoplastic urethane (TPU).(f) Non-flexible coating: a coating which lacks the ability to withstand dimensional changes; non-flexible substrates utilizing non-flexible coatings include sheet molding compound (SMC), nylon, polyester, ABS, Xenoy polycarbonate, and acrylic.(g) Plastic part: a piece made from a substance that has been formed from a resin through the application of pressure or heat or both.(h) Waterborne coating: a coating which contains more than fifty percent by weight water in its volatile fraction.(3) EMISSION STANDARDS. Each owner or operator of a source subject to this rule shall limit VOC emissions from finishing operations by one of the following methods: (a) Each owner or operator of a source subject to this rule shall not cause or allow the application of any coating with VOC content in excess of these amounts: 1. Business machines, Medical equipment housing, Entertainment equipment housing and Miscellaneous plastic parts: | COATING | VOC (lb/gal) |

(b) Each owner or operator of a plastic parts coating line subject to this rule shall not: 1. Apply coatings on that line, during any one day, whose weighted average VOC content for any category exceeds the emission limits in Subparagraph (3)(a) of this rule.2. Apply coatings on that line, during any one day, whose weighted average VOC content exceeds the emission limits in Subparagraph (3)(a) of this rule by performing the calculation in paragraph .82(1) of this chapter. The calculation shall be for the daily total of all coatings of the appropriate coating category in Subparagraph (3)(a) above used in all lines subject to this rule, if such calculation is consistent with all approved lowest achievable emission rate determinations for the lines involved.(c) Each owner or operator shall apply control device requirements as follows: 1. An owner or operator of a plastic coating line subject to this rule may comply with this rule by: (i) Installing and operating a capture system and a control device on that line;(ii) 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; and(iii) Demonstrating each day that the overall emission reduction efficiency achieved is greater than or equal to the overall emission reduction efficiency required.2. An owner or operator of a plastic coating line subject to this rule electing to comply with the requirements of part 1. of this subparagraph shall ensure that:(i) 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 in this chapter, and(ii) 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.(3) COMPLIANCE CERTIFICATION, RECORDKEEPING AND REPORTING REQUIREMENTS. The owner or operator of an affected source subject to this rule shall: (a) Demonstrate compliance with this rule by using the applicable test methods specified in this chapter;(b) Except the for waterborne coatings the methods for determining VOC content may be batch formulation data certified as accurate by the coating supplier. With respect to compliance certification, initiation of recordkeeping and reporting, and completion of control system compliance testing of a source, the owner or operator of that source shall comply with the requirements of rule .03 of this chapter, except that the applicable date for initial compliance and certification and performance testing shall be November 15, 1996, rather than April 22, 1994.
With respect to petitioning for a source-specific compliance schedule according to and as provided for in rule .07 of this chapter, the owner or operator shall insure the petition is reviewed by the Technical Secretary no later than October 1, 1995, rather than October 22, 1993.
