| For each . . . | You must . . . | Or you must . . . |
|---|---|---|
| 1. Tunnel or roller kiln equipped with a DIFF or DLS/FF | a. If you use a bag leak detection system, initiate corrective action within 1 hour of a bag leak detection system alarm and complete corrective actions in accordance with your OM&M plan; operate and maintain the fabric filter such that the alarm is not engaged for more than 5 percent of the total operating time in a 6-month block reporting period; and | i. Maintain no VE from the DIFF or DLS/FF stack; or ii. Maintain your kiln operating temperature within the range of acceptable temperatures (i.e., temperature profile established for each kiln and product. |
| b. Maintain free-flowing lime in the feed hopper or silo and to the APCD at all times for continuous injection systems; maintain the feeder setting (on a per ton of throughput basis) at or above the level established during the performance test for continuous injection systems in which compliance was demonstrated | ||
| 2. Tunnel or roller kiln equipped with a WS | a. Maintain the average scrubber liquid pH for each 3-hour block period at or above the average scrubber liquid pH established during the HF/HCl performance test in which compliance was demonstrated; and | |
| b. Maintain the average scrubber liquid flow rate for each 3-hour block period at or above the highest average scrubber liquid flow rate established during the HF/HCl and PM performance tests in which compliance was demonstrated | ||
| 3. Tunnel or roller kiln equipped with an ACI system | Maintain the 3-hour block average carbon flow rate at or above the highest average carbon flow rate established during the Hg and dioxin/furan performance tests in which compliance was demonstrated | |
| 4. Tunnel or roller kiln intending to comply with dioxin/furan emission limit without an ACI system | Maintain the average operating temperature for each 12-hour block period at or below the highest operating temperature established during the dioxin/furan performance test in which compliance was demonstrated | i. Maintain your kiln operating temperature within the range of acceptable temperatures (i.e., temperature profile established for each kiln and product. |
| 5. Tunnel or roller kiln with no add-on control | a. Maintain no VE from the stack; and | |
| b. Maintain the kiln process rate at or below the kiln process rate determined according to §63.8595(g)(1) if your total facility maximum potential HCl-equivalent emissions are greater than the HCl-equivalent limit in Table 1 to this subpart; and | ||
| c. Maintain the average operating temperature for each 12-hour block period at or below the highest operating temperature established during the dioxin/furan performance test in which compliance was demonstrated | i. Maintain no VE from the FF stack. | |
| 6. Glaze spray operation equipped with a FF | a. If you use a bag leak detection system, initiate corrective action within 1 hour of a bag leak detection system alarm and complete corrective actions in accordance with your OM&M plan; operate and maintain the fabric filter such that the alarm is not engaged for more than 5 percent of the total operating time in a 6-month block reporting period | |
| 7. Glaze spray operation equipped with a WS | a. Maintain the average scrubber pressure drop for each 3-hour block period at or above the average pressure drop established during the PM performance test in which compliance was demonstrated; and | |
| b. Maintain the average scrubber liquid flow rate for each 3-hour block period at or above the average scrubber liquid flow rate established during the PM performance test in which compliance was demonstrated | ||
| 8. Glaze spray operation equipped with a water curtain | a. Conduct daily inspections to verify the presence of water flow to the wet control system; and | |
| b. Conduct annual inspections of the interior of the control equipment (if applicable) to determine the structural integrity and condition of the control equipment | ||
| 9. Glaze spray operation equipped with baffles | Conduct an annual visual inspection of the baffles to confirm the baffles are in place | |
| 10. Spray dryer | Maintain the average operating temperature for each 4-hour block period at or above the average temperature established during the dioxin/furan performance test in which compliance was demonstrated | |
| 11. Floor tile press dryer | Maintain the average operating temperature for each 4-hour block period at or below the average temperature established during the dioxin/furan performance test in which compliance was demonstrated. |
