| 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
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. | 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.
|
| 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
| |
| 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 your kiln operating temperature within the range of acceptable temperatures (i.e., temperature profile) established for each kiln and product.
|
| 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. | i. Maintain no VE from the FF stack.
|
| 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. | |
