Each new and existing kiln that is used to process clay refractory products that is subject to the PM limits specified in items 10.c. 11.c, 12.a, and 13.a of Table 1 to this subpart | Measure PM emissions | Method 5 of 40 CFR part 60, appendix A-3 | 22. Each new and existing kiln that is used to process clay refractory products that is subject to the Hg limits specified in items 10.d. 11.d, 12.b, and 13.b of Table 1 to this subpart | Measure Hg emissions | Method 29 of 40 CFR part 60, appendix A-8 | ASTM D6784-16 a may be used as an alternative to EPA Method 29 (portion for Hg only). | 23. Each new and existing kiln that is used to process clay refractory products and is equipped with an activated carbon injection 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. | 24.
