As stated in §63.8445, you must conduct each performance test in the following table that applies to you:
Open Table
| For each . . . | You must . . . | Using . . . | According to the following requirements . . . |
|---|---|---|---|
| 1. Tunnel kiln | a. Select locations of sampling ports and the number of traverse points | Method 1 or 1A of 40 CFR part 60, appendix A-1 | Sampling sites must be located at the outlet of the APCD and prior to any releases to the atmosphere for all affected sources. |
| b. Determine velocities and volumetric flow rate | Method 2 of 40 CFR part 60, appendix A-1 | You may use Method 2A, 2C, 2D, or 2F of 40 CFR part 60, appendix A-1, or Method 2G of 40 CFR part 60, appendix A-2, as appropriate, as an alternative to using Method 2 of 40 CFR part 60, appendix A-1. | |
| c. Conduct gas molecular weight analysis | Method 3 of 40 CFR part 60, appendix A-2 | You may use Method 3A or 3B of 40 CFR part 60, appendix A-2, as appropriate, as an alternative to using Method 3 of 40 CFR part 60, appendix A-2. ANSI/ASME PTC 19.10-1981 (incorporated by reference, see §63.14) may be used as an alternative to the manual procedures (but not the instrumental procedures) in Methods 3A and 3B. | |
| d. Measure moisture content of the stack gas | Method 4 of 40 CFR part 60, appendix A-3 | ||
| e. Measure HF, HCl and Cl2 emissions | i. Method 26A of 40 CFR part 60, appendix A-8; or | You may use Method 26 of 40 CFR part 60, appendix A-8, as an alternative to using Method 26A of 40 CFR part 60, appendix A-8, when no acid PM (e.g., HF or HCl dissolved in water droplets emitted by sources controlled by a WS) is present. ASTM D6735-01 (Reapproved 2009) (incorporated by reference, see §63.14) may be used as an alternative to Methods 26 and 26A. | |
| ii. Method 320 of appendix A of this part | When using Method 320 of appendix A of this part, you must follow the analyte spiking procedures of section 13 of Method 320 of appendix A of this part, unless you can demonstrate that the complete spiking procedure has been conducted at a similar source. ASTM D6348-03 (Reapproved 2010) (incorporated by reference, see §63.14) may be used as an alternative to Method 320 if the test plan preparation and implementation in Annexes A1-A8 are mandatory and the %R in Annex A5 is determined for each target analyte. | ||
| f. Measure PM emissions or non-Hg HAP metals | i. For PM only: Method 5 of 40 CFR part 60, appendix A-3; or | ||
| ii. For PM or non-Hg HAP metals: Method 29 of 40 CFR part 60, appendix A-8 | |||
| g. Measure Hg emissions | Method 29 of 40 CFR part 60, appendix A-8 | ASTM D6784-02 (Reapproved 2008) (incorporated by reference, see §63.14) may be used as an alternative to Method 29 (portion for Hg only). | |
| 2. Tunnel kiln with no add-on control | Establish the operating limit(s) for kiln process rate if the total facility maximum potential HCl-equivalent emissions are greater than the HCl-equivalent limit in Table 1 to this subpart | HCl-equivalent limit in Table 1 to this subpart and emissions and production data from the HF/HCl/Cl2 performance test | Using the procedures in §63.8445(g)(1), you must determine the maximum process rate(s) for your kiln(s) that would ensure total facility maximum potential HCl-equivalent emissions remain at or below the HCl-equivalent limit in Table 1 to this subpart. The maximum process rate(s) would become your site-specific process rate operating limit(s). |
| 3. Tunnel kiln that is complying with PM and/or Hg production-based emission limits | Determine the production rate during each PM/Hg test run in order to determine compliance with PM and/or Hg production-based emission limits | Production data collected during the PM/Hg performance tests (e.g., no. of pushes per hour, no. of bricks per kiln car, weight of a typical fired brick) | You must measure and record the production rate, on a fired-product basis, of the affected source for each of the three test runs. |
| 4. Tunnel kiln equipped with a DLA | a. Establish the operating limit for the average pressure drop across the DLA | Data from the pressure drop measurement device during the HF/HCl/Cl2 performance test | You must continuously measure the pressure drop across the DLA, determine and record the block average pressure drop values for the three test runs, and determine and record the 3-hour block average of the recorded pressure drop measurements for the three test runs. The average of the three test runs establishes your minimum site-specific pressure drop operating limit. |
| b. Establish the operating limit for the limestone feeder setting | Data from the limestone feeder during the HF/HCl/Cl2 performance test | You must ensure that you maintain an adequate amount of limestone in the limestone hopper, storage bin (located at the top of the DLA), and DLA at all times during the performance test. You must establish your limestone feeder setting, on a per ton of fired product basis, one week prior to the performance test and maintain the feeder setting for the one-week period that precedes the performance test and during the performance test. | |
| c. Document the source and grade of limestone used | Records of limestone purchase | ||
| 5. Tunnel kiln equipped with a DIFF or DLS/FF | Establish the operating limit for the lime feeder setting | Data from the lime feeder during the HF/HCl/Cl2 performance test | For continuous lime injection systems, you must ensure that lime in the feed hopper or silo and to the APCD is free-flowing at all times during the performance test and record the feeder setting, on a per ton of fired product basis, for the three test runs. If the feed rate setting varies during the three test runs, determine and record the average feed rate from the three test runs. The average of the three test runs establishes your minimum site-specific feed rate operating limit. |
| 6. Tunnel kiln equipped with a WS | a. Establish the operating limit for the average scrubber liquid pH | Data from the pH measurement device during the performance HF/HCl/Cl2 performance test | You must continuously measure the scrubber liquid pH, determine and record the block average pH values for the three test runs, and determine and record the 3-hour block average of the recorded pH measurements for the three test runs. The average of the three test runs establishes your minimum site-specific liquid pH operating limit. |
| b. Establish the operating limit for the average scrubber liquid flow rate | Data from the flow rate measurement device during the HF/HCl/Cl2 and PM/non-Hg HAP metals performance tests | You must continuously measure the scrubber liquid flow rate, determine and record the block average flow rate values for the three test runs, and determine and record the 3-hour block average of the recorded flow rate measurements for the three test runs. The average of the three test runs establishes your minimum site-specific liquid flow rate operating level. If different average wet scrubber liquid flow rate values are measured during the HF/HCl/Cl2 and PM/non-Hg HAP metals tests, the highest of the average values become your site-specific operating limit. | |
| 7. Tunnel kiln equipped with an ACI system | Establish the operating limit for the average carbon flow rate | Data from the carbon flow rate measurement conducted during the Hg performance test | You must measure the carbon flow rate during each test run, determine and record the block average carbon flow rate values for the three test runs, and determine and record the 3-hour block average of the recorded carbon flow rate measurements for the three test runs. The average of the three test runs establishes your minimum site-specific activated carbon flow rate operating limit. |
