Section 20.2.32.114 - EMISSION MONITORING

A. The owner or operator of a facility subject to 20.2.32.111 NMAC shall install, calibrate, maintain and operate a CEMS, approved by the Department, which shall continuously measure and record nitrogen dioxide concentrations in the flue gases released into the atmosphere from each unit of coal burning equipment. Continuous emissions monitoring shall apply during all periods of operation of the coal burning equipment, including periods of startup, shutdown and malfunction, except for CEMS breakdowns, repair, calibration checks, and zero and span adjustment. All sampling points for monitoring nitrogen dioxide concentrations shall be approved in writing by the Department.

B. The CEMS required by this section shall complete a minimum of one cycle of operation (sampling, analyzing, and data recording) for each successive 15 minute period. One-hour averages shall be computed from four or more data points equally spaced over each one-hour period. Data recorded during periods of CEMS breakdown, repairs, calibration checks and zero and span adjustments shall not be included in the daily averages computed under this paragraph.

C. When CEMS emission data required under this section are not obtained because of CEMS breakdowns, repairs, calibration checks and zero and span adjustments, emission data will be obtained by using other monitoring systems approved by the Department and the Administrator or one of the reference methods specified by the US EPA in 40 CFR Part 60, Appendix A, to provide emission data for a minimum of 18 hours in each day, midnight to midnight, in at least 22 out of 30 successive days.

D. The CEMS installed and used pursuant to this section shall be operated, installed and maintained in accordance with the performance specifications and other requirements set forth by the US EPA in 40 CFR Part 60, Appendix B, Performance Specifications 2 and 3. In the event of significant breakdown of the CEMS, the owner or operator shall demonstrate to the Department after the repair work that the CEMS continues to meet the applicable performance specifications. The Department may require the owner or operator to conduct a performance test of the equipment as specified in 40 CFR Part 60, Appendix B, but not more frequently than once per year unless the Department has reason to believe that the CEMS is not operating within the applicable performance specifications. An alternate means of verifying the performance of the CEMS may be used if approved by the Department and the Administrator. The Department may also perform independent audits on the CEMS.

E. Each CEMS required under this section shall be subject to the quality assurance requirements of 40 CFR Part 60, Appendix F. All reports required thereunder shall be submitted to the Department.
