Table 4 of Subpart AAAAAAA of Part 63—Operating Limits
If you comply with the emission limits using * * * You must establish an operating value for * * * And maintain a * * *
a The 3-hour averaging period applies at all times other than startup and shutdown, as defined in § 63.2. Within 24 hours of a startup event, or 24 hours prior to a shutdown event, you must normalize the emissions that occur during the startup or shutdown, when there is no production rate available to assess compliance with the lb/ton of product emission limits, with emissions that occur when the process is operational. The emissions that occur during the startup or shutdown event must be included with the process emissions when assessing compliance with the emission limits specified in Tables 1 and 2 of this subpart.
b As an alternative to monitoring the inlet gas temperature and pressure drop, you can use a leak detection system that identifies when the filter media has been comprised.
c As an alternative to monitoring the ESP voltage, you can monitor the ESP instrumentation (e.g. light, alarm) that indicates when the ESP must be cleaned and maintain a record of the instrumentation on an hourly basis. Failure to service the ESP within one hour of the indication is an exceedance of the applicable monitoring requirements specified in § 63.11563(a).
d If you are not using a control device to comply with the emission limits specified in Table 2 of this subpart, the process parameters and corresponding parameter values that you select to demonstrate continuous compliance must correlate to the process emissions.
1. A thermal oxidizer Combustion zone temperature The 3-hour average combustion zone temperature at or above the operating value established as specified in § 63.11562(a)(2) and (b)(2).
2. A high-efficiency air filter or fiber bed filter a. Inlet gas temperature b, andb. Pressure drop across device b The 3-hour average inlet gas temperature within the operating range established as specified in § 63.11562(a)(2) and (b)(3).The 3-hour average pressure drop across the device within the approved operating range established as specified in § 63.11562(a)(2) and (b)(3).
3. An electrostatic precipitator (ESP) Voltage c to the ESP The 3-hour average ESP voltage c at or above the approved operating value established as specified in § 63.11562(a)(2) and (b)(3).
4. Process modifications (i.e., a control device is not required) Appropriate process monitoring parameters.d The monitoring parameters within the operating values established as specified in § 63.11562(c)(2).
