501.3.2 A person using emission control equipment as a means of alternate compliance with this rule pursuant to Section 304, shall maintain daily records of key system operating and maintenance procedures which will demonstrate continuous operation and co mpliance of the emission control system during periods of emission- producing activities. Key system operating parameters are those necessary to ensure compliance with the requirements of Section 304, and as defined in Section 235.

501.4 Retention of Records : All records required by this rule shall be retained for at least three years, except for sources subject to Rule 507, Federal Operating Permit Program , which shall be retained for at least five years. Such records shall be made available to the Air Pollution Control Officer, upon request.

502 VOC EMISSION THRESHOLD: If VOC emissions for any calendar year exceed 10,000 pounds, additional recordkeeping documentation will be required per Rule 511, Potential To

Emit.

503 TEST METHODS:

503.1 Determintation of VOC Content : VOC content of coatings, solvents, strippers and surface preparation materials shall be determined in accordance with United States Environmental Protection Agency (USEPA) Method 24 or Method 24A.

503.2 Determination of Compounds Exempt From VOC Definition : Exempt compounds referenced in Section 224 and listed in Rule 102, Definitions , shall be determined in
accordance with ASTM D 4457-85 “Standard Test Method for Determination ofAugust 20, 2009

Placer County APCD Rules and Regulations 245
− 13 Dichloromethane and 1,1,1-Tricholorethane in Paints and Coatings by Direct Injection into a Gas Chromatograph” or California Air Resources Board Method 432 “Determination of Dichloromethane and 1,1,1-Tricholorethane in Paints and Coatings”. If any perfluorocarbons or volat ile cyclic and linear methyl siloxanes are being claimed as exempt compounds, the person making the claim must state in advance which compounds are present and the USEPA-approved test method used to make the determination of these compounds.

503.3 Determination of Control Efficiency : Control efficiency of emissions control equipment referenced in Section 304, shall be determined in accordance with USEPA Method 25 or 25A: and USEPA Method 2 or 2C (whichever is applicable). USEPA Method 18 or CARB Method 422 “Determination of Volatile Organic Compounds in Emissions from Stationary Sources” may be used to determine emissions of exempt compounds.

503.4 Determination of Collection Efficiency : Collection efficiency of the control equipment
referenced in Section 304 shall be determined in accordance with U.S.EPA’s “Guidelines for Determining Capture E fficiency, January 9, 1995”. Individual collection efficiency test runs subject to the U.S.EPA’s technical guidelines shall be determined by:

503.4.1 40 CFR 51, Appendix M, Methods 204-204F; or

503.4.2 The South Coast AQMD “Protocol for Determination of Volatile Organic Compound (VOC) Capture Efficiency”; or

503.4.3 Any other method approved by the USEPA, the California Air Resources Board, and the Air Pollution Control Officer.

503.5 Metallic/Iridescent Topcoat : The determination of a coating as metallic/iridescent shall be made using the South Coast Air Quality Management District “Spectrographic Method for the Analysis of Carbon Dust and Carbon Laminates,

December 1985”.

503.6 Acid Content : The acid content of pretreatment wash primers shall be measured and reported in accordance with South Coast Air Quality Management District “Laboratory Methods for Analysis for Enforcement Samples”, and ASTM D1613-06 “Standard Test Method for Acidity in Volatile Solvents and Chemical Intermediates Used in Paint, Varnish, Lacquer, and Related Products”.

503.7 Emissions From Spray Gun Cleaning Systems : Determination of emissions of VOC from spray gun cleaning systems shall be made using South Coast Air Quality Management District “General Method for Determining Solvent Losses From Spray Gun Cleaning Systems”, October 1989.

503.8 Transfer Efficiency : Determination of transfer efficiency shall be made using South Coast Air Quality Management District Te st Method “Spray Equipment Transfer Efficiency Test Procedure for Equipment Users”, May 24, 1989.

503.9 Multiple Test Methods : When more than one test method or a 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 te st methods shall constitute a violation of

this rule.August 20, 2009
