Open Table
| For each control device used to meet the emission limit in Table 1 or 2 to this subpart for the following pollutant . . . | You must . . . | Using . . . |
|---|---|---|
| 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. |
