Section 117.2135 - Monitoring, Notification, and Testing Requirements(a) Oxygen (O) monitors. If the owner or operator installs an O monitor, the criteria in § 117.8100(a) of this title (relating to Emission Monitoring System Requirements for Industrial, Commercial, and Institutional Sources) should be considered the appropriate guidance for the location and calibration of the monitor.(b) Nitrogen oxides (NO) monitors. If the owner or operator installs a continuous emissions monitoring system (CEMS) or predictive emissions monitoring system (PEMS), the CEMS or PEMS must meet the requirements of § 117.8100(a) or (b) of this title. If a PEMS is used, the PEMS must predict the pollution emissions in the units of the applicable emission limitations of this division.(c) Monitor installation schedule. Installation of monitors must be performed in accordance with the schedule specified in § 117.9210 of this title (relating to Compliance Schedule for Dallas-Fort Worth Eight-Hour Ozone Nonattainment Area Minor Sources).(d) Testing requirements. The owner or operator of any unit subject to § 117.2110 of this title (relating to Emission Specifications for Eight-Hour Attainment Demonstration) shall comply with the following testing requirements. (1) Each unit must be tested for NO, carbon monoxide (CO), and O emissions.(2) One of the ammonia monitoring procedures specified in § 117.8130 of this title (relating to Ammonia Monitoring) must be used to demonstrate compliance with the ammonia emission specification of § 117.2110(h)(2) of this title for units that inject urea or ammonia into the exhaust stream for NO control.(3) For units not equipped with CEMS or PEMS, all testing must be conducted according to § 117.8000 of this title (relating to Stack Testing Requirements). In lieu of the test methods specified in § 117.8000 of this title, the owner or operator may use American Society for Testing and Materials (ASTM) D6522-00 to perform the NO, CO, and O testing required by this subsection on natural gas-fired reciprocating engines. If the owner or operator elects to use ASTM D6522-00 for the testing requirements, the report must contain the information specified in § 117.8010 of this title (relating to Compliance Stack Test Reports).(4) Test results must be reported in the units of the applicable emission specifications and averaging periods. If compliance testing is based on 40 Code of Federal Regulations Part 60, Appendix A reference methods, the report must contain the information specified in § 117.8010 of this title.(5) For units equipped with CEMS or PEMS, the CEMS or PEMS must be installed and operational before testing under this subsection. Verification of operational status must, at a minimum, include completion of the initial monitor certification and the manufacturer's written requirements or recommendations for installation, operation, and calibration of the device.(6) Initial compliance with the emission specifications of § 117.2110 of this title for units operating with CEMS or PEMS must be demonstrated after monitor certification testing using the NO CEMS or PEMS.(7) For units not operating with CEMS or PEMS, the following apply.(A) Retesting as specified in paragraphs (1) - (4) of this subsection is required within 60 days after any modification that could reasonably be expected to increase the NO emission rate.(B) Retesting as specified in paragraphs (1) - (4) of this subsection may be conducted at the discretion of the owner or operator after any modification that could reasonably be expected to decrease the NO emission rate, including, but not limited to, installation of post-combustion controls, low-NO burners, low excess air operation, staged combustion (for example, overfire air), flue gas recirculation, and fuel-lean and conventional (fuel-rich) reburn.(C) Stationary, reciprocating internal combustion engines not equipped with CEMS or PEMS must be periodically tested for NO and CO emissions as specified in § 117.8140(a) of this title (relating to Emission Monitoring for Engines).(8) Testing must be performed in accordance with the schedule specified in § 117.9210 of this title.(9) All test reports must be submitted to the executive director for review and approval within 60 days after completion of the testing.(10) The owner or operator of an affected unit in the Dallas-Fort Worth eight-hour ozone nonattainment area must submit written notification of any CEMS or PEMS relative accuracy test audit (RATA) or testing required under this section to the appropriate regional office and any local air pollution control agency having jurisdiction at least 15 days in advance of the date of RATA or testing.(e) Run time meters. The owner or operator of any stationary diesel engine claimed exempt using the exemption of §117.2103(5), (8), (9), or (10) of this title (relating to Exemptions) shall record the operating time with a non-resettable elapsed run time meter.30 Tex.
