- Table 3 to Subpart AAAAA of Part 63—Operating Limits
As required in § 63.7090(b), you must meet each operating limit in the following table that applies to you, except for kilns and coolers during startup and shutdown (See table 2 to this subpart for operating limits during startup and shutdown).
| For . . . | You must . . . | 1. Each lime kiln and each lime cooler (if there is a separate exhaust to the atmosphere from the associated lime cooler) equipped with an FF | Maintain and operate the FF such that the BLDS or PM detector alarm condition does not exist for more than 5 percent of the total operating time in a 6-month period; and comply with the requirements in § 63.7113(d) through (f) and table 6 to this subpart. In lieu of a BLDS or PM detector maintain the FF such that the 6-minute average opacity for any 6-minute block period does not exceed 15 percent; and comply with the requirements in § 63.7113(f) and (g) and table 6 to this subpart. | 2. Each lime kiln equipped with a wet scrubber | a. Maintain the 3-hour block exhaust gas stream pressure drop across the wet scrubber greater than or equal to the greater of the pressure drop operating limit established during the most recent performance test for PM and HCl; and
b. Maintain the 3-hour block scrubbing liquid flow rate greater than or equal to the greater of the flow rate operating limit established during the most recent performance test for PM and HCl. | 3. Each lime kiln equipped with an electrostatic precipitator | Install a PM detector and maintain and operate the ESP such that the PM detector alarm is not activated and alarm condition does not exist for more than 5 percent of the total operating time in a 6-month period, and comply with § 63.7113(e); or, maintain the ESP such that the 6-minute average opacity for any 6-minute block period does not exceed 15 percent, and comply with the requirements in § 63.7113(g); and comply with the requirements in § 63.7113(f) and table 6 to this subpart. | 4. Each PSH operation subject to a PM limit which uses a wet scrubber | Maintain the 3-hour block average exhaust gas stream pressure drop across the wet scrubber greater than or equal to the greater of the pressure drop operating limit established during the performance test for PM and HCl; and maintain the 3-hour block average scrubbing liquid flow rate greater than or equal to the greater of the flow rate operating limit established during the performance test for PM and HCl. | 5. All affected sources | Prepare a written OM&M plan; the plan must include the items listed in § 63.7100(d) and the corrective actions to be taken when required in table 6 to this subpart. | 6. Each emission unit equipped with an add-on air pollution control device | a. Vent captured emissions through a closed system, except that dilution air may be added to emission streams for the purpose of controlling temperature at the inlet to an FF; and
b. Operate each capture/collection system according to the procedures and requirements in the OM&M plan. | 7. Each lime kiln equipped with dry sorbent injection | Maintain the 3-hour block dry sorbent flow rate greater than or equal to the flow rate operating limit established during the most recent performance test for HCl. | 8. Each lime kiln equipped with a thermal oxidizer | Maintain the 3-hour block average combustion chamber temperature greater or equal to the greater of the combustion chamber operating limit established in the most recent performance test for total organic HAP and D/F. | 9. Each lime kiln equipped with activated carbon injection | Maintain the 3-hour block activated carbon injection flow rate greater than or equal to the greater of the flow rate operating limit established during the most recent performance test for total organic HAP, D/F, and mercury. |
