Title 40Chapter ISubchapter CPart 63Subpart UUU → Appendix


Title 40: Protection of Environment
PART 63—NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS FOR SOURCE CATEGORIES (CONTINUED)
Subpart UUU—National Emission Standards for Hazardous Air Pollutants for Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming Units, and Sulfur Recovery Units


Table 11 to Subpart UUU of Part 63—Requirements for Performance Tests for Organic HAP Emissions From Catalytic Cracking Units Not Subject to New Source Performance Standard (NSPS) for Carbon Monoxide (CO)

As stated in §63.1565(b)(2) and (3), you shall meet each requirement in the following table that applies to you.

For .  .  .You must .  .  .Using .  .  .According to these requirements .  .  .
1. Each new or existing catalytic cracking unit catalyst regenerator vent.a. Select sampling port's location and the number of traverse ports.Method 1 or 1A in appendix A to part 60 of this chapter.Sampling sites must be located at the outlet of the control device or the outlet of the regenerator, as applicable, and prior to any releases to the atmosphere.
   b. Determine velocity and volumetric flow rate.Method 2, 2A, 2D, 2F, or 2G in appendix A to part 60 of this chapter, as applicable.
   c. Conduct gas molecular weight analysis.Method 3, 3A, or 3B in appendix A to part 60 of this chapter, as applicable.
   d. Measure moisture content of the stack gas.Method 4 in appendix A to part 60 of this chapter.
2. For each new or existing catalytic cracking unit catalyst regenerator vent if you use a continuous emission monitoring system.Measure CO emissionsData from your continuous emission monitoring system.Collect CO monitoring data for each vent for 24 consecutive operating hours; and reduce the continuous emission monitoring data to 1-hour averages computed from four or more data points equally spaced over each 1-hour period.
3. Each catalytic cracking unit catalyst regenerator vent if you use continuous parameter monitoring systemsa. Measure the CO concentration (dry basis) of emissions exiting the control deviceMethod 10, 10A, or 10B in appendix A-4 to part 60 of this chapter, as applicable
   b. Establish each operating limit in Table 9 of this subpart that applies to youData from the continuous parameter monitoring systems
   c. Thermal incinerator combustion zone temperatureData from the continuous parameter monitoring systemsCollect temperature monitoring data every 15 minutes during the entire period of the CO initial performance test; and determine and record the minimum hourly average combustion zone temperature from all the readings.
   d. Thermal incinerator: oxygen, content (percent, dry basis) in the incinerator vent streamData from the continuous parameter monitoring systemsCollect oxygen concentration (percent, dry basis) monitoring data every 15 minutes during the entire period of the CO initial performance test; and determine and record the minimum hourly average percent excess oxygen concentration from all the readings.
   e. If you use a 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, establish operating limit for combustion zone temperatureData from the continuous parameter monitoring systemsCollect the temperature monitoring data every 15 minutes during the entire period of the CO initial performance test; and determine and record the minimum hourly average combustion zone temperature from all the readings.
   f. If you use a flare, conduct visible emission observationsMethod 22 (40 CFR part 60, appendix A-7)On and after January 30, 2019, meet the requirements of §63.670. Prior to January 30, 2019, maintain a 2-hour observation period; and record the presence of a flame at the pilot light over the full period of the test or meet the requirements of §63.670.
   g. If you use a flare, determine that the flare meets the requirements for net heating value of the gas being combusted and exit velocity40 CFR 63.11(b)(6) through (8)On and after January 30, 2019, the flare must meet the requirements of §63.670. Prior to January 30, 2019, the flare must meet the control device requirements in §63.11(b) or the requirements of §63.670.
