Approved by EPA September 1, 2000 (65 FR 53172) effective October 31, 2000.

     (a)  The owner or operator of any facility subject to the provisions of this undesignated head (relating to Adipic Acid Manufacturing) shall install, calibrate, maintain, and operate a continuous emissions monitoring system (CEMS) for measuring nitrogen oxides (NO_x) from the absorber.

     (b)  Any CEMS installed subject to subsection (a) of this section shall meet all requirements of 40 Code of Federal Regulations (CFR), Part 60, §60.13; 40 CFR 60, Appendix B, Performance Specification 2; and quality assurance procedures of 40 CFR 60, Appendix F, except that a cylinder gas audit may be performed in lieu of the annual relative accuracy test audit required in Section 5.1.1.

     (c)  As an alternative to CEMS, the owner or operator of units subject to continuous monitoring requirements under this undesignated head may, with the approval of the executive director, elect to install, calibrate, maintain, and operate a predictive emissions monitoring system (PEMS).  The required PEMS shall be used to measure NO_x emissions for each affected unit and shall be used to demonstrate continuous compliance with the emission limitations of §117.305 of this title (relating to Emission Specifications.  Any PEMS shall meet the requirements of §117.319 of this title (relating to Notification, Recordkeeping, and Reporting Requirements) and §117.213(c)(1)-(3) of this title (relating to Continuous Demonstration of Compliance).

     (d)  The owner or operator of an affected facility shall establish a conversion factor for the purpose of converting monitoring data into units of the emission standard (in pounds NO_x per ton of acid produced) as specified in 40 CFR 60, Subpart G, §60.73(b).  NO_x emissions data recorded by the CEMS or PEMS shall be represented in terms of both parts per million by volume and pounds NO_x per ton of acid produced.

     (e)  After the initial demonstration of compliance required by §117.311 of this title (relating to Initial Demon-stration of Compliance), compliance with §117.305 of this title shall be determined by the methods required in this section.  Compliance with the emission limitations may also be determined at the discretion of the executive director using any Texas Natural Resource Conservation Commission compliance method.
