Appendix - Table 17 to Subpart XXXX of Part 63—Initial Compliance With the Emission Limits for Rubber Processing Affected Sources

As stated in § 63.6011, you must show initial compliance with the emission limits for the rubber processing affected source and conduct performance tests according to the following table:

For the following emission limit . . . You must do the following . . .
1. The applicable THC emission limit in table 15 to this subparta. Continuously measure THC emissions using a THC CEMS and mass of mixed rubber compounds processed over a period of not less than 15 days.
b. Use the applicable methods in item 2 in this table to measure exhaust flow rate in dry standard cubic feet per minute to determine THC mass emissions in grams per day using the equations and procedures in § 63.6011.
c. Demonstrate that you have achieved the applicable THC emission limits in table 15 to this subpart according to the applicable procedures in § 63.6011.
2. The applicable fPM emission limit in table 15 to this subparta. Conduct the performance test according to the site-specific plan submitted according to § 63.7(c)(2)(i).
b. Measure fPM and the mass of mixed rubber compound processed for at least 3 runs lasting at least 1 hour per run.
c. Use Method 5 in appendix A-3 to 40 CFR part 60 to measure fPM emissions.
d. Select sampling ports' location and the number of traverse ports according to Method 1 or 1A of 40 CFR part 60, appendix A-1.
e. Determine velocity and volumetric flow rate according to Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A-1 and A-2.
f. Conduct the gas analysis according to Method 3, 3A, or 3B of 40 CFR part 60, appendix A-2; as an alternative to the manual portion of Method 3B, you may use ANSI/ASME PTC 19.10-1981 (incorporated by reference; see § 63.14).
g. Measure moisture content of the stack gas using Method 4 of 40 CFR part 60, appendix A-3.
h. Demonstrate that you have achieved the applicable fPM emission limit in table 15 to this subpart according to the applicable procedures in § 63.6011.
i. Install, operate, and maintain the BLDS according to the requirements in § 63.6012(c) at the time of the initial compliance test. Standard operating procedures for the BLDS must be incorporated into the monitoring plan required by § 63.5990(e).
3. The applicable metal HAP alternative emission limit in table 15 to this subparta. Conduct the performance test according to the site-specific plan submitted according to § 63.7(c)(2)(i).
b. Measure metal HAP emissions and mass of mixed rubber compound processed for at least 3 runs lasting at least 1 hour per run.
c. Use Method 29 in appendix A-8 to 40 CFR part 60 to measure metal HAP emissions. As an alternative to Method 29 for mercury only, you may use the particulate mercury portion of ASTM D6784-16 to measure particulate mercury emissions (incorporated by reference; see § 63.14).
d. Select sampling ports' location and the number of traverse ports according to Method 1 or 1A of 40 CFR part 60, appendix A-1.
e. Determine velocity and volumetric flow rate according to Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A-1 and A-2.
f. Conduct the gas analysis according to Method 3, 3A, or 3B of 40 CFR part 60, appendix A-2; as an alternative to the manual portion of Method 3B, you may use ANSI/ASME PTC 19.10-1981 (incorporated by reference; see § 63.14).
g. Measure moisture content of the stack gas using Method 4 of 40 CFR part 60, appendix A-3.
h. Demonstrate that you have achieved the applicable metal HAP emission limit in table 15 to this subpart according to the applicable procedures in § 63.6011.
i. Install, operate, and maintain the BLDS according to the requirements in § 63.6012(c) at the time of the initial compliance test. Standard operating procedures for the BLDS must be incorporated into the monitoring plan required by § 63.5990(e).
