§ 129.71a. Control of VOC emissions from the synthetic organic chemical manufacturing industry—air oxidation, distillation and reactor processes.
(a) Applicability.
(1) Except as specified in paragraph (3), this section applies to the owner and operator of a synthetic organic chemical manufacturing facility that has a vent stream originating from a process unit in which an air oxidation unit process, distillation operation or reactor process produces one or more of the chemicals listed in Table 1 as a product, coproduct, byproduct or intermediate.
(2) For purposes of this section, reference to total organic compounds or TOC in 40 CFR Part 60, Subpart III (relating to standards of performance for volatile organic compound (VOC) emissions from the Synthetic Organic Chemical Manufacturing Industry (SOCMI) air oxidation unit processes), 40 CFR Part 60, Subpart NNN (relating to standards of performance for volatile organic compound (VOC) emissions from Synthetic Organic Chemical Manufacturing Industry (SOCMI) distillation operations) or 40 CFR Part 60, Subpart RRR (relating to standards of performance for volatile organic compound (VOC) emissions from Synthetic Organic Chemical Manufacturing Industry (SOCMI) reactor processes) shall be considered equivalent to VOC as defined in § 121.1 (relating to definitions).
(3) The owner and operator of a synthetic organic chemical manufacturing facility located in this Commonwealth that has a vent stream originating from a process unit in which an air oxidation unit process, distillation operation or reactor process produces one or more of the chemicals listed in Table 1 as a product, coproduct, byproduct or intermediate shall meet the requirements of this section unless more stringent requirements in an applicable permit or plan approval issued by the Department apply.
(b) Standards.
(1) Process vents. For a process vent that is subject to equivalent VOC control provisions under an existing 40 CFR Part 60 (relating to standards of performance for new stationary sources) or 40 CFR Part 63 (relating to National emission standards for hazardous air pollutants for source categories) standard, compliance with the requirements of the existing 40 CFR Part 60 or 63 standard shall constitute compliance with the provisions of this section.
(2) Air oxidation unit processes.
(i) The owner or operator of a source with an air oxidation unit process meeting the applicability criteria in subsection (a) shall comply with the requirements of 40 CFR Part 60, Subpart III unless the source has RACT control measures approved in a permit as part of the Commonwealth’s Federally approved SIP prior to January 21, 2023.

(vii) Notwithstanding 40 CFR 60.614(c), the Department reserves the option to require testing at other times as may be required.
(3) Distillation operations.
(i) The owner or operator of a source with a distillation operation subject to subsection (a) shall comply with the requirements of 40 CFR Part 60, Subpart NNN.
