40 CFR Appendix Table 18 to Subpart UUU of Part 63, Requirements for Performance Tests for Organic HAP Emissions From Catalytic Reforming Units

Table 18 to Subpart UUU of Part 63 - Requirements for Performance Tests for Organic HAP Emissions From Catalytic Reforming Units

As stated in § 63.1566(b)(2) and (3), you shall meet each requirement in the following table that applies to you.

For each new or existing catalytic reforming unit . . . You must . . . Using . . . According to these
requirements . . .
1. Option 1: Vent to a flare a. Conduct visible emission observations Method 22 ( 40 CFR part 60 , appendix A-7) On and after January 30, 2019, the flare must meet the requirements of § 63.670 . Prior to January 30, 2019, 2-hour observation period. Record the presence of a flame at the pilot light over the full period of the test, or the requirements of § 63.670 .
b. Determine that the flare meets the requirements for net heating value of the gas being combusted and exit velocity 40 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 .
2. Option 2: Percent reduction or concentration limit a. Select sampling site Method 1 or 1A ( 40 CFR part 60 , appendix A). No traverse site selection method is needed for vents smaller than 0.10 meter in diameter. Sampling sites must be located at the inlet (if you elect the emission reduction standard) and outlet of the control device and prior to any releases to the atmosphere.
b. Measure gas volumetric flow rate Method 2, 2A, 2C, 2D, 2F, or 2G ( 40 CFR part 60 , appendix A), as applicable
c. Measure TOC concentration (for percent reduction standard) Method 25 (40 part 60, appendix A) to measure nonmethane TOC concentration (in carbon equivalents) at inlet and outlet of the control device. If the nonmethane TOC outlet concentration is expected to be less than 50 ppm (as carbon), you can use Method 25A to measure TOC concentration (as hexane) at the inlet and the outlet of the control device. If you use Method 25A, you may use Method 18 ( 40 CFR part 60 , appendix A) to measure the methane concentration to determine the nonmethane TOC concentration Take either an integrated sample or four grab samples during each run. If you use a grab sampling technique, take the samples at approximately equal intervals in time, such as 15-minute intervals during the run.
d. Calculate TOC or nonmethane TOC emission rate and mass emission reduction Calculate emission rate by Equation 1 of § 63.1566 (if you use Method 25) or Equation 2 of § 63.1566 (if you use Method 25A). Calculate mass emission reduction by Equation 3 of § 63.1566 .
e. For concentration standard, measure TOC concentration. (Optional: Measure methane concentration.) Method 25A ( 40 CFR part 60 , appendix A) to measure TOC concentration (as hexane) at the outlet of the control device. You may elect to use Method 18 ( 40 CFR part 60 , appendix A) to measure the methane concentration
f. Determine oxygen content in the gas stream at the outlet of the control device Method 3A or 3B ( 40 CFR part 60 , appendix A), as applicable
g. Calculate the TOC or nonmethane TOC concentration corrected for oxygen content (for concentration standard) Equation 4 of § 63.1566
h. Establish each operating limit in Table 16 of this subpart that applies to you for a thermal incinerator, or 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 flame zone Data from the continuous parameter monitoring systems Collect the temperature monitoring data every 15 minutes during the entire period of the initial TOC performance test. Determine and record the minimum hourly average combustion zone temperature.
i. If you do not use a control device, document the purging conditions used prior to testing following the minimum requirements in the operation, maintenance, and monitoring plan. Data from monitoring systems as identified in the operation, maintenance, and monitoring plan Procedures in the operation, maintenance, and monitoring plan.
