NR 440.76(9)(d)3.3. For initial and annual evaluations, you shall collect data concurrently, or within 30 to 60 minutes, using your oxygen or carbon dioxide continuous emission monitoring system, your sulfur dioxide, nitrogen oxides, or carbon monoxide continuous emission monitoring systems, as appropriate, and the appropriate test methods specified in Table 3 of this section. You shall collect the data during each initial and annual evaluation of your continuous emission monitoring systems following the applicable performance specifications in 40 CFR part 60, Appendix B, incorporated by reference in s. NR 440.17 (1). Table 4 of this section shows the performance specifications that apply to each continuous emission monitoring system.
NR 440.76(9)(d)4.4. You shall follow the quality assurance procedures in 40 CFR part 60, Appendix F, Procedure 1, incorporated by reference in s. NR 440.17 (1), for each continuous emission monitoring system. The procedures include daily calibration drift and quarterly accuracy determinations.
NR 440.76(9)(e)(e) Am I exempt from any requirements to evaluate continuous emission monitoring systems under 40 CFR part 60, Appendix B or F, incorporated by reference in s. NR 440.17 (1)? Yes, the accuracy tests for your sulfur dioxide continuous emission monitoring system require you to also evaluate your oxygen or carbon dioxide continuous emission monitoring system. Therefore, your oxygen or carbon dioxide continuous emission monitoring system is exempt from the following 2 requirements:
NR 440.76(9)(e)1.1. Relative accuracy requirement in 40 CFR part 60, Appendix B, section 2.3 of Performance Specification 3, incorporated by reference in s. NR 440.17 (1).
NR 440.76(9)(e)2.2. Relative accuracy test audit in 40 CFR part 60, Appendix F, section 5.1.1, incorporated by reference in s. NR 440.17 (1).
NR 440.76(9)(f)(f) What is my schedule for evaluating continuous emission monitoring systems?
NR 440.76(9)(f)1.1. You shall conduct annual evaluations of your continuous emission monitoring systems no more than 13 months after the previous evaluation was conducted.
NR 440.76(9)(f)2.2. You shall evaluate your continuous emission monitoring systems daily and quarterly as specified in 40 CFR part 60, Appendix F, incorporated by reference in s. NR 440.17 (1).
NR 440.76(9)(g)(g) What must I do if I choose to monitor carbon dioxide instead of oxygen as a diluent gas? You shall establish the relationship between oxygen and carbon dioxide during the initial evaluation of your continuous emission monitoring systems. You may reestablish the relationship during annual evaluations. To establish the relationship, use the following 3 procedures:
NR 440.76(9)(g)1.1. Use Method 3A or 3B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), to determine oxygen concentration at the location of your carbon dioxide monitor.
NR 440.76(9)(g)2.2. Conduct at least 3 test runs for oxygen. Make sure each test run represents a 1-hour average and that sampling continues for at least 30 minutes in each hour.
NR 440.76(9)(g)3.3. Use the fuel-factor equation in Method 3B in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), to determine the relationship between oxygen and carbon dioxide.
NR 440.76(9)(h)(h) What is the minimum amount of monitoring data I must collect with my continuous emission monitoring systems and is the data collection requirement enforceable?
NR 440.76(9)(h)1.1. Where continuous emission monitoring systems are required, you shall obtain 1-hour arithmetic averages. Make sure the averages for sulfur dioxide, nitrogen oxides and carbon monoxide are in parts per million by dry volume at 7% oxygen, or the equivalent carbon dioxide level. Use the 1-hour averages of oxygen or carbon dioxide data from your continuous emission monitoring system to determine the actual oxygen or carbon dioxide level and to calculate emissions at 7% oxygen, or the equivalent carbon dioxide level.
NR 440.76(9)(h)2.2. You shall obtain at least 2 data points per hour in order to calculate a valid 1-hour arithmetic average. Section NR 440.13 (5) (b) requires your continuous emission monitoring systems to complete at least one cycle of operation, sampling, analyzing and data recording for each 15-minute period.
NR 440.76(9)(h)3.3. You shall obtain valid 1-hour averages for 75% of the operating hours per day for 90% of the operating days per calendar quarter. An operating day is any day the unit combusts any municipal solid waste or refuse-derived fuel.
NR 440.76(9)(h)4.4. If you do not obtain the minimum data required in subds. 1. to 3., you are in violation of the data collection requirement regardless of the emission level monitored, and you shall notify the department according to sub. (13) (h) 5.
NR 440.76(9)(h)5.5. If you do not obtain the minimum data required in subds. 1. to 3., you shall still use all valid data from the continuous emission monitoring systems in calculating emission concentrations and percent reductions in accordance with par. (i).
NR 440.76(9)(i)(i) How do I convert my 1-hour arithmetic averages into the appropriate averaging times and units?
NR 440.76(9)(i)1.1. You shall use the equation in sub. (15) (a) to calculate emissions at 7% oxygen.
NR 440.76(9)(i)2.2. You shall use section 4.3 of Method 19 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), to calculate the daily geometric average concentrations of sulfur dioxide emissions. If you are monitoring the percent reduction of sulfur dioxide, use section 5.4 of Method 19 to determine the daily geometric average percent reduction of potential sulfur dioxide emissions.
NR 440.76(9)(i)3.3. If you operate a Class I municipal waste combustion unit, you shall use section 4.1 of Method 19 to calculate the daily arithmetic average for concentrations of nitrogen oxides.
NR 440.76(9)(i)4.4. You shall use section 4.1 of Method 19 to calculate the 4-hour or 24-hour daily block averages, as applicable, for concentrations of carbon monoxide.
NR 440.76(9)(j)(j) What is required for my continuous opacity monitoring system and how are the data used?
NR 440.76(9)(j)1.1. You shall install, calibrate, maintain and operate a continuous opacity monitoring system.
NR 440.76(9)(j)2.2. You shall install, evaluate and operate each continuous opacity monitoring system according to s. NR 440.13.
NR 440.76(9)(j)3.3. You shall complete an initial evaluation of your continuous opacity monitoring system according to Performance Specification 1 in 40 CFR part 60, Appendix B, incorporated by reference in s. NR 440.17 (1). You shall complete the evaluation within 60 days after your municipal waste combustion unit reaches the maximum load level at which it will operate, but no more than 180 days after its initial startup.
NR 440.76(9)(j)4.4. You shall complete each annual evaluation of your continuous opacity monitoring system no more than 13 months after the previous evaluation.
NR 440.76(9)(j)5.5. You shall use tests conducted according to Method 9 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), as specified in sub. (10) (d), to determine compliance with the opacity limit in Table 1 of this section.
