35.4. Test methods and procedures.

35.4.1. To be in compliance with paragraph 35.3.3.a., each owner or operator of a petroleum solvent dry cleaning facility subject to this section 35. shall:

35.4.1.a. Calculate the weight of VOCs vented from the dryer emission control device calculated by using Methods 1, 2, and 25A of 40 CFR Part 60, Appendix A with the following specifications:

35.4.1.a.1. Field calibration of the flame ionization analyzer with propane standards;

35.4.1.a.2. Laboratory determination of the ratio of the flame ionization analyzer response to a given parts per million (ppm) by volume concentration of propane to the response to the same ppm concentration of the VOCs to be measured; and

35.4.1.a.3. Determination of the weight of VOCs vented to the atmosphere by:

35.4.1.a.3.A. Multiplying the ratio determined in subparagraph 35.4.1.a.2. by the measured concentration of VOC gas (as propane) as indicated by the flame ionization analyzer response output record;
