Requirements for Performance Tests and Design Evaluations
June 9, 2020
As stated in §§63.2354(a) and 63.2362, you must comply with the requirements for performance tests and design evaluations for existing, reconstructed, or new affected sources as follows:
Open Table
| For . . . | You must conduct . . . |
According to . . . | Using . . . | To determine . . . | According to the following requirements . . . |
|---|---|---|---|---|---|
| 1. Each existing, each reconstructed, and each new affected source using a nonflare control device to comply with an emission limit in Table 2 to this subpart, items 1 through 10 | a. A performance test to determine the organic HAP (or, upon approval, TOC) control efficiency of each nonflare control device, OR the exhaust concentration of each combustion device; OR | i. §63.985(b)(1)(ii), §63.988(b), §63.990(b), or §63.995(b) | (1) EPA Method 1 or 1A in appendix A-1 of 40 CFR part 60, as appropriate | (A) Sampling port locations and the required number of traverse points | (i) Sampling sites must be located at the inlet and outlet of each control device if complying with the control efficiency requirement or at the outlet of the control device if complying with the exhaust concentration requirement; AND (ii) the outlet sampling site must be located at each control device prior to any releases to the atmosphere. |
| (2) EPA Method 2, 2A, 2C, 2D, or 2F in appendix A-1 of 40 CFR part 60, or EPA Method 2G in appendix A-2 of 40 CFR part 60, as appropriate | (A) Stack gas velocity and volumetric flow rate | See the requirements in items 1.a.i.(1)(A)(i) and (ii) of this table. | |||
| (3) EPA Method 3 or 3B in appendix A-2 of 40 CFR part 60, as appropriate | (A) Concentration of CO2 and O2 and dry molecular weight of the stack gas | See the requirements in items 1.a.i.(1)(A)(i) and (ii) of this table. | |||
| (4) EPA Method 4 in appendix A-3 of 40 CFR part 60 | (A) Moisture content of the stack gas | See the requirements in items 1.a.i.(1)(A)(i) and (ii) of this table. | |||
| (5) EPA Method 18 in appendix A-6 of 40 CFR part 60, or EPA Method 25 or 25A in appendix A-7 of 40 CFR part 60, as appropriate, or EPA Method 316 in appendix A of 40 CFR part 63 for measuring form-aldehyde | (A) Total organic HAP (or, upon approval, TOC), or formaldehyde emissions | (i) The organic HAP used for the calibration gas for EPA Method 25A in appendix A-7 of 40 CFR part 60 must be the single organic HAP representing the largest percent by volume of emissions; AND (ii) During the performance test, you must establish the operating parameter limits within which total organic HAP (or, upon approval, TOC) emissions are reduced by the required weight-percent or, as an option for nonflare combustion devices, to 20 ppmv exhaust concentration. |
|||
| b. A design evaluation (for nonflare control devices) to determine the organic HAP (or, upon approval, TOC) control efficiency of each nonflare control device, or the exhaust concentration of each combustion control device | §63.985(b)(1)(i) | During a design evaluation, you must establish the operating parameter limits within which total organic HAP, (or, upon approval, TOC) emissions are reduced by at least 95 weight-percent for storage tanks or 98 weight-percent for transfer racks, or, as an option for nonflare combustion devices, to 20 ppmv exhaust concentration. | |||
| 2. Each transport vehicle that you own that is equipped with vapor collection equipment and is loaded with organic liquids at a transfer rack that is subject to control based on the criteria specified in table 2 to this subpart, items 7 through 10, at an existing, reconstructed, or new affected source | A performance test to determine the vapor tightness of the tank and then repair as needed until it passes the test. | EPA Method 27 in appendix A of 40 CFR part 60 | Vapor tightness | The pressure change in the tank must be no more than 250 pascals (1 inch of water) in 5 minutes after it is pressurized to 4,500 pascals (18 inches of water). |
