from this rule for low volume of solvent usage, pursuant to 

Section 104.1, shall maintain records of the type and volume 

of solvent used, as required by Section 502, on an annual 

basis.

501.4 Emission Control Equipment: Any person using emission control equipment 

pursuant to this rule shall maintain records, on a daily basis, of key system 

operating parameters for emission control equipment, including, but not limited

available to the Air Pollution Control Officer upon request.

503 TEST METHODS

503.1 Determination of VOC Content: VOC content of solvents shall be determined in 

accordance with United States Environmental Protection Agency (U.S. EPA) 

Method 24 and Sections 401 and 503.2 of this rule.

503.2 Determination Of Compounds Exempt From VOC Definition: Compounds 

exempt from the VOC definition, as listed in Rule 102, Definitions, shall be 

determined in accordance with ASTM D4457-91 or ARB Method 432. If any of 

the perfluorocarbons or volatile 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 EPA-approved test method 

used to make the determination of these compounds.

503.3 Determination Of VOC Composite Partial Pressure: VOC composite partial 

pressure shall be determined in accordance with ASTM E260-96 for organic 

compounds, and ASTM D3792-91 for water content as applicable, and Sections 

403 and 503.4 of this rule.

503.4 Determination of Vapor Pressure: Vapor pressure of a VOC shall be determined 

in accordance with ASTM Method D2879-96, or may be obtained from a 

published source such as:

503.4.1 "The Vapor Pressure of Pure Substances", Boublik, Fried, and Hala; 

Elsevier Scientific Publishing Company, New York, 1973.

503.4.2 "Perry's Chemical Engineer's Handbook", McGraw-Hill Book Company, 

1984.
