control device. The control efficiency of the air pollution control device shall be 

determined using EPA Reference Methods 25A and/or 18 (40 CFR Part 60, Appendix 

A) and in accordance with a protocol approved by the Air Pollution Control Officer.

Test Methods 204 and 204A through 204F (51 CFR Appendix M), as applicable, and 

technical document, “Guidelines for Determining Capture Efficiency,” dated January 9, 

1995. Subsequent to the initial compliance demonstration period, appropriate key 

system operating parameters as approved by the Air Pollution Control Officer may be 

used as indicators of the performance of the emission control system.

(9) Other test methods which are determined to be equivalent to the test methods 

specified in this rule and approved, in writing, by the Air Pollution Control Officer, 

California Air Resources Board, and EPA may be used in place of the test methods 

specified in this rule. 

(1) Perfluorocarbon (PFC) compounds shall be assumed to be absent from a coating, cleaning, or surface preparation material subject to this rule unless a manufacturer of 

the material or a facility operator identifies the specific individual compound(s) and the 

amount(s) present in the material and provides an EPA and Air Resources Board 

approved test method which can be used to quantify the specific compounds.

(2) Measurements of transfer efficiency subject to Subsection (d)(1)(vii) of this 

rule shall be conducted in accordance with the South Coast Air Quality Management 

District’s "Spray Equipment Transfer Efficiency Test Procedure for Equipment User," as 

it exists on September 25, 2002.

(3) Measurement of the VOC content of coatings, surface preparation and 

cleaning materials subject to Subsections (d)(2), (d)(3), (d)(4), (d)(5)(i), or (d)(6)(i) of
