Any waiver request must also be accompanied with documentation of the reference method measured concentration, and documentation that it is less than 50% of the emission limit or standard. The waiver must be based on the measured value at the time of the waiver.

When required by this chapter, the owner or operator shall monitor carbon monoxide (CO) exhaust emissions from an affected unit using one or more of the following methods: (1) install, calibrate, maintain, and operate a: (A) continuous emissions monitoring system (CEMS) in accordance with (a) or (a) of this title (relating to Emission Monitoring System Requirements for Industrial, Commercial, and Institutional Sources; and Emission Monitoring System Requirements for Utility Electric Generation Sources), as applicable; or (B) predictive emissions monitoring system (PEMS) in accordance with (b) or (b) of this title, as applicable; or (2) sample CO as follows: (A) with a portable analyzer (or 40 Code of Federal Regulations (CFR) Part 60, Appendix A reference method test apparatus) after manual combustion tuning or manual burner adjustments conducted for the purpose of minimizing nitrogen oxides (NOX) emissions whenever, following such manual changes, either of the following occur:
13 Texas Commission on Environmental Quality Page 13 (i) NOX emissions are sampled with a portable analyzer or 40 CFR Part 60, Appendix A reference method test apparatus; or (ii) the resulting NOX emissions measured by CEMS or predicted by PEMS are lower than levels when CO emissions data was previously gathered; and (B) sample CO emissions using the test methods and procedures of 40 CFR Part 60 in conjunction with any relative accuracy test audit of the NO X and diluent analyzer. Adopted May 23, 2007 Effective June 14, Ammonia Monitoring. When required by this chapter, one of the following ammonia monitoring procedures must be used to demonstrate compliance with the applicable ammonia emission specifications of this chapter for gas-fired or liquid-fired units that inject urea or ammonia into the exhaust stream for nitrogen oxides (NOX) control. (1) Mass balance. Ammonia emissions are calculated as the difference between the input ammonia, measured by the ammonia injection rate, and the ammonia reacted, measured by the differential NOX upstream and downstream of the control device that injects urea or ammonia into the exhaust stream. The ammonia emissions must be calculated using the following equation. Figure: 30 TAC (1) Where: a 6 NH O2 = 10 c d b = ammonia parts per million by volume (ppmv) at reference oxygen. Reference oxygen on a dry basis is 3.0% for boilers and process heaters; 0.0% for fluid catalytic cracking units (including carbon monoxide (CO) boilers, CO furnaces, and catalyst regenerator vents); 7.0% for boilers and industrial furnaces that were regulated as existing facilities by the United States Environmental Protection Agency 40 Code of Federal Regulations Part 266, Subpart H (as was in effect on June 9, 1993), wood-fired boilers, and incinerators; 15% for stationary gas turbines (including duct burners used in turbine
14 Texas Commission on Environmental Quality Page 14 exhaust ducts), gas-fired lean-burn engines, and lightweight aggregate kilns; and 3.0% for all other units; a = ammonia injection rate (in pounds per hour (lb/hr))/17 pound per pound-mole (lb/lb-mol); b = dry exhaust flow rate (lb/hr)/29 lb/lb-mol; c = change in measured NOX concentration across catalyst (ppmv at reference oxygen); and d = correction factor, the ratio of measured slip to calculated ammonia slip, where the measured slip is obtained from the stack sampling for ammonia during an initial demonstration of compliance required by this chapter and using the methods specified in of this title (relating to Stack Testing Requirements). (2) Oxidation of ammonia to nitric oxide (NO). Convert ammonia to NO using a molybdenum oxidizer and measure ammonia slip by difference using a NO analyzer. The NO analyzer must be quality assured in accordance with the manufacturer's specifications and with a quarterly cylinder gas audit with a 10 parts per million by volume (ppmv) reference sample of ammonia passed through the probe and confirming monitor response to within ± 2.0 ppmv. (3) Stain tubes. Measure ammonia using a sorbent or stain tube device specific for ammonia measurement in the 5.0 to 10.0 ppmv range. The frequency of sorbent/stain tube testing must be daily for the first 60 days of operation. After the first 60 days of operation, the frequency may be reduced to weekly testing if operating procedures have been developed to prevent excess amounts of ammonia from being introduced in the control device and when operation of the control device has been proven successful with regard to controlling ammonia slip. Daily sorbent or stain tube testing must resume when the catalyst is within 30 days of its useful life expectancy. Every effort must be made to take at least one weekly sample near the normal highest ammonia injection rate. (4) Other methods. Monitor ammonia using another continuous emissions monitoring system or predictive emissions monitoring system procedure subject to prior approval of the executive director. Adopted May 23, 2007 Effective June 14, Emission Monitoring for Engines.
15 Texas Commission on Environmental Quality Page 15 (a) Periodic testing. When required by this chapter, the owner or operator of any stationary internal combustion engine shall test engine nitrogen oxides (NOX) and carbon monoxide (CO) emissions as follows. (1) The methods specified in of this title (relating to Stack Testing Requirements) must be used. (2) The owner or operators shall sample: (A) on a biennial calendar basis; or (B) within 15,000 hours of engine operation after the previous emission test, under the following conditions: (i) install and operate an elapsed operating time meter; and (ii) submit, in writing, to the executive director and any local air pollution agency having jurisdiction, biennially after the initial demonstration of compliance: (I) documentation of the actual recorded hours of engine operation since the previous emission test; and sampling. (II) an estimate of the date of the next required (3) Engines used exclusively in emergency situations are not required to conduct the testing specified in paragraph (2) of this subsection. (b) Proper operation. When required by this chapter, the owner or operator of any stationary internal combustion engine shall check the engine for proper operation by recorded measurements of engine NOX and CO emissions at least quarterly and as soon as practicable within two weeks after each occurrence of engine maintenance that may reasonably be expected to increase emissions, oxygen sensor replacement, or catalyst cleaning or catalyst replacement. Stain tube indicators specifically designed to measure NOX concentrations may be acceptable for this documentation, provided a hot air probe or equivalent device is used to prevent error due to high stack temperature, and three sets of concentration measurements are made and averaged. Portable NOX analyzers are also acceptable for this documentation. Quarterly emission testing is not required for those engines whose monthly run time does not exceed ten hours. This exemption does not diminish the requirement to test emissions after the installation of controls, major repair work, and any time the owner or operator believes emissions may have changed.
