Appendix - Table 5 to Subpart EEEE of Part 63—Requirements for Performance Tests and Design Evaluations

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:

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, and each existing affected source using a nonflare control device to comply with an emission limit in Table 2b to this subpart, items 1 through 3	a. A performance test to determine the organic HAP (or, upon a pproval, 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) 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) Method 2, 2A, 2C, 2D, or 2F in appendix A-1 of 40 CFR part 60, or 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) Method 3A or 3B in appendix A-2 of 40 CFR part 60, as appropriate ¹	(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) 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) Method 25 or 25A in appendix A-7 of 40 CFR part 60, as appropriate. Method 316, Method 320 ⁴, or Method 323 in appendix A of this part if you must measure formaldehyde. You may not use Methods 320 2 4 or 323 for formaldehyde if the gas stream contains entrained water droplets	(A) TOC and formaldehyde emissions, from any control device	(i) The organic HAP used for the calibration gas for 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 TOC emissions are reduced by the required weight-percent or, as an option for nonflare combustion devices, to 20-ppmv exhaust concentration.
			(6) Method 18 ³ in appendix A-6 of 40 CFR part 60 or Method 320 2 4 of appendix A to this part, as appropriate. Method 316, Method 320 2 4, or Method 323 in appendix A of this part for measuring formaldehyde. You may not use Methods 320 or 323 if the gas stream contains entrained water droplets	(A) Total organic HAP and formaldehyde emissions, from non-combustion control devices	(i) During the performance test, you must establish the operating parameter limits within which total organic HAP emissions are reduced by the required weight-percent.
	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		Method 27 of 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).

¹ The manual method in American Society of Mechanical Engineers (ASME) PTC 19.10-1981-Part 10 (2010) (incorporated by reference, see § 63.14) may be used instead of Method 3B in appendix A-2 of 40 CFR part 60 to determine oxygen concentration.

² All compounds quantified by Method 320 of appendix A to this part must be validated according to Section 13.0 of Method 320.

³ ASTM D6420-18 (incorporated by reference, see § 63.14) may be used instead of Method 18 of 40 CFR part 60, appendix A-6 to determine total HAP emissions, but if you use ASTM D6420-18, you must use it under the conditions specified in § 63.2354(b)(3)(ii).

⁴ ASTM D6348-12e1 (incorporated by reference, see § 63.14) may be used instead of Method 320 of appendix A to this part under the following conditions: the test plan preparation and implementation in the Annexes to ASTM D6348-12e1, Sections A1 through A8 are mandatory; the percent (%) R must be determined for each target analyte (Equation A5.5); %R must be 70% ≥ R ≤ 130%; if the %R value does not meet this criterion for a target compound, then the test data is not acceptable for that compound and the test must be repeated for that analyte (i.e., the sampling and/or analytical procedure should be adjusted before a retest); and the %R value for each compound must be reported in the test report and all field measurements must be corrected with the calculated %R value for that compound by using the following equation: Reported Results = ((Measured Concentration in Stack))/(%R) × 100.
