June 9, 2020
As stated in §63.1565(b)(1), you shall meet each requirement in the following table that applies to you.
Open Table
| For each new or existing catalytic cracking unit . . . |
And you use this type of control device for your vent . . . | You shall install, operate, and maintain this type of continuous monitoring system . . . |
|---|---|---|
| 1. Subject to the NSPS for carbon monoxide (CO) in 40 CFR 60.103 or 60.102a(b)(4) | Not applicable | Continuous emission monitoring system to measure and record the concentration by volume (dry basis) of CO emissions from each catalyst regenerator vent. |
| 2. Not subject to the NSPS for CO in 40 CFR 60.103 or 60.102a(b)(4) | a. Thermal incinerator | Continuous emission monitoring system to measure and record the concentration by volume (dry basis) of CO emissions from each catalyst regenerator vent; or continuous parameter monitoring systems to measure and record the combustion zone temperature and oxygen content (percent, dry basis) in the incinerator vent stream. |
| b. Process heater or boiler with a design heat input capacity under 44 MW or process heater or boiler in which all vent streams are not introduced into the flame zone. | Continuous emission monitoring system to measure and record the concentration by volume (dry basis) of CO emissions from each catalyst regenerator vent; or continuous parameter monitoring systems to measure and record the combustion zone temperature. | |
| c. Flare | On and after January 30, 2019, the monitoring systems required in §§63.670 and 63.671. Prior to January 30, 2019, monitoring device such as a thermocouple, an ultraviolet beam sensor, or infrared sensor to continuously detect the presence of a pilot flame, or the monitoring systems required in §§63.670 and 63.671. | |
| d. No control device | Continuous emission monitoring system to measure and record the concentration by volume (dry basis) of CO emissions from each catalyst regenerator vent. | |
| 3. During periods of startup, shutdown or hot standby electing to comply with the operating limit in §63.1565(a)(5)(ii) | Any | Continuous parameter monitoring system to measure and record the concentration by volume (wet or dry basis) of oxygen from each catalyst regenerator vent. If measurement is made on a wet basis, you must comply with the limit as measured (no moisture correction). |
