Appendix - Table 3 to Subpart LLLLL of Part 63—Requirements for Performance Tests a b

For—	You must—	Using—	According to the following requirements—
1. All particulate matter, total hydrocarbon, carbon monoxide, and carbon dioxide emission tests	a. Select sampling port's location and the number of traverse points	i. EPA test method 1 or 1A in appendix A to part 60 of this chapter	A. For demonstrating compliance with the total hydrocarbon percent reduction standard, the sampling sites must be located at the inlet and outlet of the control device prior to any releases to the atmosphere.
			B. For demonstrating compliance with the particulate matter mass emission rate, THC destruction efficiency, THC outlet concentration, or combustion efficiency standards, the sampling sites must be located at the outlet of the control device prior to any releases to the atmosphere.
2. All particulate matter and total hydrocarbon tests	Determine velocity and volumetric flow rate	EPA test method 2, 2A, 2C, 2D, 2F, or 2G, as appropriate, in appendix A to part 60 of this chapter
3. All particulate matter and total hydrocarbon tests	Determine the gas molecular weight used for flow rate determination	EPA test method 3, 3A, 3B, as appropriate, in appendix A to part 60 of this chapter
4. All particulate matter, total hydrocarbon, carbon monoxide, and carbon dioxide emission tests	Measure moisture content of the stack gas	EPA test method 4 in appendix A to part 60 of this chapter
5. All particulate matter emission tests	Measure the asphalt processing rate or the asphalt roofing manufacturing rate and the asphalt content of the product manufactured, as appropriate
6. Each control device used to comply with the particulate matter emission standards	Measure the concentration of particulate matter	EPA test method 5A in appendix A to part 60 of this chapter	For demonstrating compliance with the particulate matter standard, the performance tests must be conducted under normal operating conditions and while manufacturing the roofing product that is expected to result in the greatest amount of hazardous air pollutant emissions.
7. All opacity tests	Conduct opacity observations	EPA test method 9 in appendix A to part 60 of this chapter, or ASTM D7520-16 d f	Conduct opacity observations for at least 3 hours and obtain 30, 6-minute averages.
8. All visible emission tests	Conduct visible emission observations	EPA test method 22 in appendix A to part 60 of this chapter	Modify EPA test method 22 such that readings are recorded every 15 seconds for a period of consecutive observations totaling 60 minutes.
9. Each combustion device used to comply with the combustion efficiency or THC standards	a. Measure the concentration of carbon dioxide b. Measure the concentration of carbon monoxide	EPA test method 3A in appendix A to part 60 of this chapter EPA test method 10 in appendix A to part 60 of this chapter
	c. Measure the concentration of total hydrocarbons	EPA test method 25A in appendix A to part 60 of this chapter
10. Each control device used to comply with the THC reduction efficiency or outlet concentration standards	Measure the concentration of total hydrocarbons	EPA test method 25A in appendix A to part 60 of this chapter
11. Each combustion device	Establish a site-specific combustion zone temperature operating limit	Data from the CPMS and the applicable performance test method(s)	You must collect combustion zone temperature data every 15 minutes during the entire period of the 3-hour performance test, and determine the average combustion zone temperature over the 3-hour performance test by computing the average of all of the 15-minute readings.
12. Each control device used to comply with the particulate matter emission standards	Establish a site-specific inlet gas temperature operating limit; and if not complying with § 63.8689(d), also establish site-specific limits for the pressure drop range (i.e., a minimum and a maximum pressure drop) across the device e	Data from the CPMS and the applicable performance test method(s)	You must collect the inlet gas temperature and pressure drop b data every 15 minutes during the entire period of the 3-hour performance test, and determine the average inlet gas temperature and pressure drop c over the 3-hour performance test by computing the average of all of the 15-minute readings. The inlet gas temperature operating limit is set at +20 percent of the test run average inlet gas temperature measured in units of degrees Celsius or degrees Fahrenheit. The maximum (or minimum) pressure drop is set as the maximum (or minimum) average pressure drop of the performance test runs which demonstrated compliance with the applicable emission limit.
13. Each control device that is neither a combustion device nor a control device used to comply with the particulate matter emission standards	Establish site-specific monitoring parameters	Process data and data from the CPMS and the applicable performance test method(s)	You must collect monitoring parameter data every 15 minutes during the entire period of the 3-hour performance test, and determine the average monitoring parameter values over the 3-hour performance test by computing the average of all of the 15-minute readings.
14. Each flare used to comply with the THC percent reduction or PM emission limits	Assure that the flare is operated and maintained in conformance with its design	The requirements of § 63.11(b)

^a For initial performance tests, as specified in § 63.8686(b), you may request that data from a previously-conducted emission test serve as documentation of conformance with the emission standards and operating limits of this subpart.

^b Performance tests are not required if: (1) The emissions are routed to a boiler or process heater with a design heat input capacity of 44 MW or greater; or (2) the emissions are introduced into the flame zone of a boiler or process heater.

^c As an alternative to monitoring the pressure drop across the control device, owners or operators using an ESP to achieve compliance with the emission limits specified in Table 1 to this subpart can monitor the voltage to the ESP.

^d If you use ASTM D7520-16 in lieu of EPA test method 9, then you must comply with the conditions specified in this footnote. During the digital camera opacity technique (DCOT) certification procedure outlined in Section 9.2 of ASTM D7520-16, you or the DCOT vendor must present the plumes in front of various backgrounds of color and contrast representing conditions anticipated during field use such as blue sky, trees, and mixed backgrounds (clouds and/or a sparse tree stand). You must also have standard operating procedures in place including daily or other frequency quality checks to ensure the equipment is within manufacturing specifications as outlined in Section 8.1 of ASTM D7520-16. You must follow the record keeping procedures outlined in § 63.10(b)(1) for the DCOT certification, compliance report, data sheets, and all raw unaltered JPEGs used for opacity and certification determination. You or the DCOT vendor must have a minimum of four (4) independent technology users apply the software to determine the visible opacity of the 300 certification plumes. For each set of 25 plumes, the user may not exceed 15 percent opacity of any one reading and the average error must not exceed 7.5 percent opacity. This approval does not provide or imply a certification or validation of any vendor's hardware or software. The onus to maintain and verify the certification and/or training of the DCOT camera, software and operator in accordance with ASTM D7520-16 and this letter is on the facility, DCOT operator, and DCOT vendor.

^e You may conduct two separate performance tests to establish the operating limits for pressure drop range (i.e., one performance test to establish a minimum pressure drop operating limit and one performance test to establish a maximum pressure drop operating limit); however, you may choose to establish either, or both, the minimum and maximum pressure drop operating limits using the requirements of § 63.8689(d) in lieu of the requirements specified in this Table.

^f Incorporated by reference, see § 63.14.
