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.
NR 440.76 NoteNote: The data obtained from your continuous opacity monitoring system are not used to determine compliance with the opacity limit.
NR 440.76(9)(k)(k) What additional requirements must I meet for the operation of my continuous emission monitoring systems and continuous opacity monitoring system? You shall use the required span values and applicable performance specifications in Table 4 of this section.
NR 440.76(9)(L)(L) What must I do if any of my continuous emission monitoring systems are temporarily unavailable to meet the data collection requirements? You shall refer to Table 4 of this section. It shows alternate methods for collecting data when systems malfunction or when repairs, calibration checks or zero and span checks keep you from collecting the minimum amount of data.
NR 440.76(10)(10)Stack testing.
NR 440.76(10)(a)(a) What types of stack tests must I conduct? You shall conduct initial and annual stack tests to measure the emission levels of dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash.
NR 440.76(10)(b)(b) How are the stack test data used? You shall use results of stack tests for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash to demonstrate compliance with the emission limits in Table 1 of this section. To demonstrate compliance for carbon monoxide, nitrogen oxides and sulfur dioxide, see sub. (9) (c).
NR 440.76(10)(c)(c) What schedule must I follow for the stack testing?
NR 440.76(10)(c)1.1. You shall conduct initial stack tests for the pollutants listed in par. (a) within 60 days after your municipal waste combustion unit reaches the maximum load level at which it will operate, but no later than 180 days after its initial startup.
NR 440.76(10)(c)2.2. You shall conduct annual stack tests for the same pollutants after the initial stack test. You shall conduct each annual stack test no later than 13 months after the previous stack test.
NR 440.76(10)(d)(d) What test methods must I use to stack test?
NR 440.76(10)(d)1.1. You shall follow Table 5 of this section to establish the sampling location and to determine pollutant concentrations, number of traverse points, individual test methods, and other specific testing requirements for the different pollutants.
NR 440.76(10)(d)2.2. You shall make sure that stack tests for all the pollutants consist of at least 3 test runs, as specified in s. NR 440.08. You shall use the average of the pollutant emission concentrations from the 3 test runs to determine compliance with the emission limits in Table 1 of this section.
