  (3) The owner or operator of a combustion control device tested under subsection (b)(3)(C) of this section electing to comply with the 275 ppmv outlet limit in the control requirements of this division shall establish a correlation between firebox or combustion chamber temperature and the VOC emissions level. The owner or operator shall also establish minimum and maximum temperatures or other operating parameters that will be continuously monitored to demonstrate the VOC concentration is equal to or less than 275 ppmv as measured at the outlet of the device.

(d) A flare used to comply with the control requirements in this division must meet the requirements of 40 CFR §60.18(b) - (f) (as amended through December 22, 2008 (73 FR 78209)).

Devices failing the visible emissions test must comply with the following.

  (1) The owner or operator shall follow the manufacturer's repair instructions, if available, or best combustion engineering practices for any necessary repairs.

  (2) Upon returning to operation from maintenance or repair activity, each device must pass an EPA Method 22 visual observation test (40 CFR Part 60, Appendix A-7, Section 11) as described in this subsection.

  (3) The owner or operator shall operate a control device following the manufacturer's written operating instructions, procedures and maintenance schedule to ensure good air pollution control practices for minimizing emissions.

(f) A control device for which a performance test is waived in accordance with 40 CFR §60.8(b) (as amended August 30, 2016 (81 FR 59809)) is exempt from the testing requirements of this section.
