1. Total hydrocarbons

a. Measure the total hydrocarbon concentration at the outlet of the final control device or in the stack

Method 25A at 40 CFR part 60, appendix A-7. Conduct each test run for a minimum of 1 hour.

2. Total organic HAP

a. Measure the total organic HAP concentration at the outlet of the final control device or in the stack

i. Method 18 at 40 CFR part 60, appendix A-6 and ASTM D6420-99.^a Conduct each test run for a minimum of 1 hour.

ii. Method 320 at 40 CFR part 63, appendix A and ASTM D6348-03.^a Conduct each test run for a minimum of 1 hour.

3. Vinyl chloride

a. Measure the vinyl chloride concentration at the outlet of the final control device or in the stack

Method 18 at 40 CFR part 60, appendix A-6. Conduct each test run for a minimum of 1 hour.

4. Hydrogen chloride

a. Measure hydrogen chloride concentrations at the outlet of the final control device or in the stack

i. Method 26 at 40 CFR part 60, appendix A-8, collect 60 dry standard liters of gas per test run; or

ii. Method 26A at 40 CFR part 60, appendix A-8, collect 1 dry standard cubic meter of gas per test run.

5. Dioxin/furan

a. Measure dioxin/furan concentrations on a toxic equivalency basis (and report total mass per isomer) at the outlet of the final control device or in the stack

Method 23 at 40 CFR part 60, appendix A-7 and collect 5 dry standard cubic meters of gas per test run.

6. Any pollutant from a continuous, batch, or combination of continuous and batch process vent(s)

a. Select sampling port locations and the number of traverse points

Method 1 or 1A at 40 CFR part 60, appendix A-1.

b. Determine gas velocity and volumetric flow rate

Method 2, 2A, 2C, 2D, 2F, or 2G at 40 CFR part 60, appendix A-1 and A-2.

c. Conduct gas molecular weight analysis and correct concentrations the specified percent oxygen in Table 1 or 2 to this subpart

Method 3, 3A, or 3B at 40 CFR part 60, appendix A-2 using the same sampling site and time as HAP samples.

d. Measure gas moisture content

Method 4 at 40 CFR part 60, appendix A-3.
