VOC content shall be displayed as grams of VOC per liter of coating (or pounds of VOC per gallon), including water and exempt compounds, pursuant to Section 404. d. For all material, recommendations r egarding thinning, reducing, or mixing with any VOC containing material, as defined in Section 251. e. For all material, VOC content may be calculated using product formulation data, or may be determined using the test method in Section 502.1.
501.3 USAGE RECORDS: Any person within the District using materials regulated by this rule shall update and maintain the records as follows: a. Monthly: 1. Records of total applied volume for each coating, coating remover (stripper), surface preparation and cleanup material, specified by category as listed in Sections 301, 302, 303, and 305. 2. The method of application, specified by coating category or other material category as listed in Sections 301, 302, and 303 including a designation for touch-up and repair operations, as applicable. 3. Records of total applied volume for each material type exceeding the VOC limits specified in Sections 301, 303, 305.3, and 305.4 by name/code/manufacturer and coating category. b. Daily: 1. If, pursuant to Section 306, an emission control device is used as a means of complying with this rule, records of the material type by name/code/manufacturer and the total applied volume of each
material. 2. For non-compliant materials, as defined in Section 236, records regarding the use, including the lack of use, of each material type by name/code/manufacturer and the total applied volume of each
material.
501.4 CONTROL EQUIPMENT: Any person using an emission control device pursuant to Section 306 as a means of complying with this rule shall maintain such records as required by the Operation and Maintenance Plan in Section 407 on a daily basis.
501.5 DURATION OF RECORDS: Such records shall be maintained on-site for five years and made available for review by the Air Pollution Control Officer upon request.

502 TESTING PROCEDURES:
502.1 DETERMINATION OF VOC CONTENT: VOC content of coatings, coating removers (strippers), and surface preparation and cl eanup material shall be determined using EPA Reference method 24 and Sections 403 and 404 of this rule and Section 502.5
of this rule.
502.2 DETERMINATION OF ACID CONTENT: Measurement of acid content shall be determined in accordance with ASTM D 1613-06.
502.3 DETERMINATION OF COLLECTION EFFICIENCY: Collection efficiency shall be determined in accordance with the U.S. EPA technical guideline document, “Guidelines for Determining Capture Effi ciency,” dated January 9, 1995. Individual capture efficiency test runs subject to U.S. EPA technical guidelines shall be determined by: a. Applicable U.S. EPA methods 204, 204A, 204B, 204C, 204D, 204E, and/or 204F; or b. Any other method approved by the U.S. EPA, the California Air Resources Board, and the Air Pollution Control Officer.SACRAMENTO METROPOLITAN AQMD RULES AND REGULATIONS

October 28, 2010 451-13 502.4 DETERMINATION OF CONTROL EFFICIENCY: Efficiency of control equipment shall be determined in accordance with EPA Method 18, 25, 25A, EPA Method 2 or 2C (whichever is applicable), and Section 405.
502.5 DETERMINATION OF COMPOUNDS EXEMPT FROM VOC DEFINITION: Compounds exempted from VOC definition, as listed in Section 220, shall be determined in accordance with ASTM D 4457-02 (2008) or ARB Method 432. If any of the perfluorocarbons are being claimed as exempt compounds, the person makingthe claim must state in advance which compounds are present, and the EPAapproved test method used to make the determination of these compounds.
502.6 DETERMINATION OF METAL CONTENT: Measurement of metal content shall be conducted and reported in accordance with the South Coast Air Quality Management District's Method 318, “Determination of Weight Percent Elemental Metals in Coatings by X-ray Diffraction”.
502.7 DETERMINATION OF SOLIDS CONTENT: Solids content of coatings shall be determined using EPA Reference method 24.
502.8 MULTIPLE TEST METHODS: When more than one test method or set of test methods is specified for any testing, a vi olation 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.SACRAMENTO METROPOLITAN AQMD RULES AND REGULATIONS
