device(s) shall be determined according to EPA’s technical document, 

“Guidelines for Determining Capture Efficiency,” January 9, 1995 and 40 

CFR 51, Appendix M, Methods 204-204F, as applicable, or any other 

method approved by EPA, ARB, and the APCO. 

6.3.3 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 control 

device. EPA Test Method 18 or ARB Method 422 (Determination of 

Volatile Organic Compounds in Emissions from Stationary Sources) 

shall be used to determine the emissions of exempt compounds. 

 

6.3.4 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 6.3.2 

CECONTROL = Control Efficiency of the control device, in 

percent, as determined in Section 6.3.3 

6.3.5 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. 
SJVUAPCD 4653 – 31 09/16/10

6.3.6 Transfer Efficiency 

Transfer efficiency shall be determined by one of the following: 

6.3.6.1 SCAQMD method “Spray Equipment Transfer Efficiency Test 

Procedure for Equipment User, May 24, 1989, or 

6.3.6.2 Any other test method for transfer efficiency for which written 

approval of the EPA and the APCO has been obtained.

6.4 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.
