|(a) Approved Test Methods and Testing Requirements. Compliance with the requirements in this division must be determined by applying one or more of the following test methods, as appropriate. As an alternative to the test methods in paragraph (1) of this subsection, the volatile organic compounds (VOC) content of coatings and, if necessary dilution solvent, may be determined by using analytical data from the material safety data sheet. (1) The owner or operator shall demonstrate compliance with the VOC limits in §115.453 of this title (relating to Control Requirements), by applying the following test methods, as appropriate. Where a test method also inadvertently measures compounds that are exempt solvent an owner or operator may exclude the exempt solvent when determining compliance with a VOC limit. The methods include: (A) Method 24 (40 Code of Federal Regulations (CFR) Part 60, Appendix A); (B) American Society for Testing and Materials (ASTM) Test Methods D1186-06.01, D1200-06.01, D3794-06.01, D2832-69, D1644-75, and D3960-81; (C) the United States Environmental Protection Agency (EPA) guidelines series document "Procedures for Certifying Quantity of Volatile Organic Compounds Emitted by Paint, Ink, and Other Coatings," EPA-450/3-84-019, as in effect December, 1984; (D) additional test procedures described in 40 CFR §60.446 (as amended through October 17, 2000 (65 FR 61761)); and (E) minor modifications to these test methods approved by the executive director. (2) The owner or operator shall determine compliance with the VOC limits for automobile and light-duty truck assembly coating processes in §115.453(a)(3) of this title by applying the following test methods in addition to paragraph (1) of this subsection, as appropriate. The methods include: (A) Protocol for Determining the Daily VOC Emission Rate of Automobile and Light-Duty Truck Topcoat Operations (EPA-453/R-08-002); (B) the procedure contained in subparagraph (A) of this paragraph for determining daily compliance with the alternative emission limitation in §115.453(a)(3) of this title for final repair. Calculation of occurrence weighted average for each combination of repair coatings (primer, specific basecoat, clearcoat) must be determined by the following procedure; (i) the relative occurrence weighted usage calculated as follows for each repair coating:
Attached Graphic (ii) the occurrence weighted average (Q) in pounds of VOC per gallon of coating (minus water and exempt solvents) as applied, for each potential combination of repair coatings calculated according to this subparagraph;
Attached Graphic (C) the procedure contained in 40 CFR Part 63, Subpart PPPP, Appendix A (as amended through April 24, 2007 (72 FR 20237)), for reactive adhesives; and (D) the procedure contained in 40 CFR Part 60, Subpart MM (as amended October 17, 2000 (65 FR 61760)) for determining the monthly weighted average for electrodeposition primer. (3) The owner or operator shall determine compliance with the vapor control system requirements in §115.453 of this title by applying the following test methods, as appropriate: (A) Methods 1 - 4 (40 CFR Part 60, Appendix A) for determining flow rates, as necessary; (B) Method 25 (40 CFR Part 60, Appendix A) for determining total gaseous nonmethane organic emissions as carbon; (C) Method 25A or 25B (40 CFR Part 60, Appendix A) for determining total gaseous organic concentrations using flame ionization or nondispersive infrared analysis; (D) additional performance test procedures described in 40 CFR §60.444 (as amended through October 18, 1983 (48 FR 48375)); or (E) minor modifications to these test methods approved by the executive director. (4) The owner or operator of a surface coating process subject to §115.453(a)(5) or (b) of this title shall measure the capture efficiency using applicable procedures outlined in 40 CFR §52.741, Subpart O, Appendix B (as amended through October 21, 1996 (61 FR 54559)). These procedures are: Procedure T - Criteria for and Verification of a Permanent or Temporary Total Enclosure; Procedure L - VOC Input; Procedure G.2 - Captured VOC Emissions (Dilution Technique); Procedure F.1 - Fugitive VOC Emissions from Temporary Enclosures; and Procedure F.2 - Fugitive VOC Emissions from Building Enclosures. (A) The following exemptions apply to capture efficiency testing requirements. (i) If a source installs a permanent total enclosure that meets the specifications of Procedure T and that directs all VOC to a control device, then the capture efficiency is assumed to be 100%, and the source is exempted from capture efficiency testing requirements. This does not exempt the source from performance of any control device efficiency testing that may be required. In addition, a source must demonstrate all criteria for a permanent total enclosure are met during testing for control efficiency. (ii) If a source uses a vapor control system designed to collect and recover VOC (e.g., carbon adsorption system), an explicit measurement of capture efficiency is not necessary if the following conditions are met. The overall control of the system can be determined by directly comparing the input liquid VOC to the recovered liquid VOC. The general procedure for use in this situation is given in 40 CFR §60.433 (as amended through October 17, 2000 (65 FR 61761)), with the following additional restrictions. (I) The source must be able to equate solvent usage with solvent recovery on a 24-hour (daily) basis, rather than a 30-day weighted average. This verification must be done within 72 hours following each 24-hour period of the 30-day period. (II) The solvent recovery system (i.e., capture and control system) must be dedicated to a single process line (e.g., one process line venting to a carbon adsorber system); or if the solvent recovery system controls multiple process lines, the source must be able to demonstrate that the overall control (i.e., the total recovered solvent VOC divided by the sum of liquid VOC input to all process lines venting to the control system) meets or exceeds the most stringent standard applicable for any process line venting to the control system. (B) The capture efficiency must be calculated using one of the following protocols referenced. Any affected source must use one of these protocols, unless a suitable alternative protocol is approved by the executive director and the EPA. (i) Gas/gas method using temporary total enclosure (TTE). The EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Procedure T. The capture efficiency equation to be used for this protocol is:
Attached Graphic (ii) Liquid/gas method using TTE. The EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Procedure T. The capture efficiency equation to be used for this protocol is:
Attached Graphic (iii) Gas/gas method using the building or room enclosure (BE) in which the affected source is located and in which the mass of VOC captured and delivered to a control device and the mass of fugitive VOC that escapes from BE are measured while operating only the affected facility. All fans and blowers in the BE must be operating as they would under normal production. The capture efficiency equation to be used for this protocol is:
Attached Graphic (iv) Liquid/gas method using a BE in which the mass of liquid VOC input to process and the mass of fugitive VOC that escapes from BE are measured while operating only the affected facility. All fans and blowers in the building or room must be operated as they would under normal production. The capture efficiency equation to be used for this protocol is:
Attached Graphic (C) The operating parameters selected for monitoring of the capture system for compliance with the requirements in §115.458(a) of this title (relating to Monitoring and Recordkeeping Requirements) must be monitored and recorded during the initial capture efficiency test and thereafter during facility operation. The executive director may require a new capture efficiency test if the operating parameter values change significantly from those recorded during the initial capture efficiency test. (5) Test methods other than those specified in paragraphs (1) - (4) of this subsection may be used if approved by the executive director and validated by Method 301 (40 CFR Part 63, Appendix A). For the purposes of this paragraph, substitute "executive director" each place that Method 301 references "administrator." (b) Inspection requirements. The owner or operator of each surface coating process subject to §115.453 of this title shall provide samples, without charge, upon request by authorized representatives of the executive director, the EPA, or any local air pollution agency with jurisdiction. The representative or inspector requesting the sample will determine the amount of coating needed to test the sample to determine compliance.
