VOC Emission Control System In lieu of complying with the requirements in Section or Section , an operator may comply with this rule by using a VOC emission control system in association with the solvent cleaning operation, provided that during emission-producing activities, the system complies with Sections and and either Section or Section , as applicable. The VOC emission control system s collection device(s) has a capture efficiency of at least 90 percent, by weight, of the emissions generated by the solvent cleaning operation and one of the following requirements: The VOC emission control system s control device(s) has a control efficiency of at least 95 percent, by weight, or The VOC emission control system has an output of less than 50 parts per million by weight (ppm) calculated as carbon with no dilution; or, If the solvent cleaning activity is associated with operations subject to Rule 4661 (Organic Solvents), the VOC emission control system shall meet the VOC emission control system overall capture and control efficiency requirements as specified in Rule 4661 (Organic Solvents). The VOC emission control system shall be approved by the APCO. SJVUAPCD 4663 - 9 9/20/2007 SAN JOAQUIN VALLEY UNIFIED AIR POLLUTION CONTROL DISTRICT In no case shall compliance through use of a VOC emission control system result in VOC emissions in excess of the VOC emissions which would result from compliance with Section or Section , as applicable. Administrative Requirements Compliance Statement Requirements Manufacturers of any solvents subject to this rule shall indicate on the solvent container, or on a separate product data sheet or material safety data sheet, the name of the solvent, manufacturer's name, the VOC content, and density of the solvent, as supplied. The VOC content shall be expressed in units of gm/liter or lb/gallon. Recordkeeping Requirements An operator shall comply with the following recordkeeping requirements: The operator shall retain the records specified in Sections through , as applicable, on site for a period of five years, make the records available on site during normal business hours to the APCO, ARB, or EPA, and submit the records to the APCO, ARB, or EPA upon request. Keep a copy of the manufacturer s product data sheet or material safety data sheet of the solvents used for organic solvent cleaning activities. Maintain a current list of solvents that are being used for organic solvent cleaning activities at the stationary source. The list shall include the following information: The name of the solvent and its manufacturer s name. The VOC content of the solvent expressed in grams/liter or lb/gallon. When the solvent is a mixture of different materials that are blended by the operator, the mix ratio of the batch shall be recorded and the VOC content of the batch shall be calculated and recorded in order to determine compliance with the specified limits of VOC content, as applied. The type of cleaning activity for each solvent that is being used at the stationary source in accordance with the applicable cleaning category specified in Table 1 of this rule. SJVUAPCD 4663 - 10 9/20/2007 SAN JOAQUIN VALLEY UNIFIED AIR POLLUTION CONTROL DISTRICT On and after September 20, 2007, the quantity of solvents used in solvent cleaning operations shall be recorded on a daily basis. An operator claiming exemption under Section shall keep records of any additional information necessary to confirm that 55 gallons or less of organic solvent products are used in all source operations subject to this rule at the stationary source in any rolling, consecutive 365-day period. An operator shall maintain usage records of non-compliant solvents on the days that non-compliant solvents are used. VOC Emission Control System Records An operator using a VOC emission control system pursuant to Section as a means of complying with this rule shall maintain daily records of the VOC emission control system s key operating parameters during periods of emission-producing operations. Key system operating parameters are those necessary to ensure compliance with VOC limits. The parameters may include, but are not limited to, temperatures, pressures, and flow rates. An operator shall keep records describing all maintenance work on the VOC emission control system that requires the VOC emission control system to be shut down. Test Methods Determination of VOC Content The VOC content of solvents and organic materials shall be determined by using EPA Test Method 24 or 24A, or SCAQMD Method 304 (Determination of Volatile Organic Compounds in Various Materials), or by using the manufacturer s product formulation data and the formula for Grams of VOC per liter of Material in Section The content of exempt halogenated VOCs shall be determined by using the ARB Method 432 or SCAQMD Method 303 (Determination of Exempt Compounds). Determination of Overall Capture and Control Efficiency of a VOC Emission Control System The capture efficiency of a VOC emission control system s collection device(s) shall be determined according to EPA s Guidelines for Determining Capture Efficiency, January 9, SJVUAPCD 4663 - 11 9/20/2007 SAN JOAQUIN VALLEY UNIFIED AIR POLLUTION CONTROL DISTRICT 1995 and 40 CFR 51, Appendix M, Methods 204-204F, as applicable, or any other method approved by EPA, ARB, and the APCO. The control efficiency of a VOC emission control system s control device(s) shall be determined using EPA Methods 2, 2A, or 2D for measuring flow rates and EPA Methods 25, 25A, or 25B for measuring total gaseous organic concentrations at the inlet and outlet of the VOC emission control system s control device. EPA Method 18 or ARB Method 422 shall be used to determine the emissions of exempt compounds. For VOC emission control systems that consist of a single VOC emission collection device connected to a single VOC emission control device, the overall capture and control efficiency shall be calculated by using the following equation: CECAPTURE AND CONTROL = [ CECAPTURE x CECONTROL ] / 100 % Where: CECAPTURE AND CONTROL = Overall Capture and Control Efficiency, in percent CECAPTURE = Capture Efficiency of the collection device, in percent, as determined in Section CECONTROL = Control Efficiency of the control device, in percent, as determined in Section Determination of Solvent Losses from Spray Gun Cleaning Systems The passive and active solvent losses from spray gun cleaning systems shall be determined by using SCAQMD General Test Method for Determining Solvent Losses from Spray Gun Cleaning Systems dated October 3, 1989. The test solvent for this determination shall be lacquer thinner with a minimum vapor pressure of 105 mm Hg at 20oC. The minimum temperature shall be 15oC. Multiple Test Methods When more than one test method or set of test methods is specified for any testing, a violation of any requirement of this rule established by any one of the specified test methods or set of test methods shall constitute a violation of this rule. SJVUAPCD 4663 - 12 9/20/2007 SAN JOAQUIN VALLEY UNIFIED AIR POLLUTION CONTROL DISTRICT Version of Test Methods All ASTM test methods referenced in Section are the most recently EPA-approved version that appears in the CFR as Materials Approved for Incorporation by Reference.
