Table 2 to Subpart AAAAA of Part 63—Startup and Shutdown Emission Limits for Kilns and Coolers
| For . . . | You must meet the following emission limit | You have demonstrated compliance, if after following the requirements in § 63.7112 . . . | 1. All new and existing lime kilns and their associated coolers equipped with an FF or an ESP during each startup | Emissions must not exceed 15 percent opacity (based on startup period block average) | i. Installed, maintained, calibrated and operated a COMS as required by the general provisions of subpart A of this part and according to PS-1 of appendix B to 40 CFR part 60, except as specified in § 63.7113(g)(2);
ii. Collected the COMS data at a frequency of at least once every 15 seconds, determining block averages for each startup period and demonstrating for each startup block period the average opacity does not exceed 15 percent. | 2. All existing lime kilns and their associated coolers that have a wet scrubber during each startup | See item 2.b of table 3 to this subpart for emission limit | See item 1 of table 6 to this subpart for requirements for demonstrating compliance. | 3. All new and existing lime kilns and their associated coolers equipped with an FF or an ESP during shutdown | Emissions must not exceed 15 percent opacity (based on 6-minute average opacity for any 6-minute block period does not exceed 15 percent) | i. Installed, maintained, calibrated and operated a COMS as required by the general provisions of subpart A of this and according to PS-1 of appendix B to 40 CFR part 60, except as specified in § 63.7113(g)(2);
ii. Collecting the COMS data at a frequency of at least once every 15 seconds, determining block averages for each 6-minute period and demonstrating for each 6-minute block period the average opacity does not exceed 15 percent. | 4. All existing lime kilns and their associated coolers that have a wet scrubber during shutdown | See item 2.b of table 3 to this subpart for emission limit | See item 1 of table 6 to this subpart for requirements for demonstrating compliance. | 5. All new and existing lime kilns that use dry sorbent injection or carbon injection during startup and shutdown | When a lime kiln is in startup or shutdown (as defined in § 63.7143), the operating limits for sorbent and/or carbon injection do not apply in table 3 to this subpart, and the lime kiln operator shall ensure that sorbent or carbon injection is in operation until the unit is no longer in startup or shutdown.
During startup and shutdown, the control device shall be operated in accordance with manufacturer's recommendations or by a site-specific operating procedure for startup and shutdown events. | 6. All new and existing lime kilns that use a thermal oxidizer during startup and shutdown | 6. When a lime kiln is in startup or shutdown (as defined in § 63.7143), the temperature limits for a thermal oxidizer in table 3 to this subpart do not apply and the lime kiln operator shall ensure that the thermal oxidizer is in operation until the unit is no longer in startup or shutdown.
During startup and shutdown, the control device shall be operated in accordance with manufacturer's recommendations or by a site-specific operating procedure for startup and shutdown events. |
