equipment shall be determined in accordance with applicable EPA Methods 

18, 25, 25A, EPA Method 2 or 2C; and Section 406. (1) U.S. EPA Method 18, 

25 or 25A, for VOC concentration, and (2) U.S. EPA Method 2 or 2C for flow 

rates, as applicable, and calculated in accordance with Section 406.

502.5502.4 Determination Of of Control Equipment Efficiency: Efficiency of the 

emission control equipment shall be based upon test measurements made in 

accordance with:

502.54.1 USEPA Method 18, 25 or 25A, for VOC concentration, and

502.54.2 USEPA Method 2 or 2C for flow rates, as applicable, and 

calculated in accordance with Section 406402.

502.65 Determination of Collection Capture Efficiency: Collection Capture efficiency 

shall be determined in accordance with U.S. EPA technical guideline 

Document, Guidelines for Developing Capture Efficiency dated January 9, 

1995.

Individual capture efficiency test runs subject to U.S. EPA technical guidelines 

shall be determined by:
