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.

(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?

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.

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.

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.

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.

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.

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.

The individual test methods in Table 5 of this section shall be used for other required equations.

5. You may apply to the department under s. NR 440.08(2) for approval to use a reference method with minor changes in methodology, to use a shorter sampling time or smaller sampling volume or for a waiver of the requirement for a performance test because you have demonstrated by other means that you are in compliance. You may apply to the administrator as allowed under s. NR 440.08(2) for approval to use an equivalent method or an alternative method the results of which the administrator has determined are adequate for demonstrating compliance.

(e) May I conduct stack testing less often?

1. You may test less often than required under par. (c) 2. if you own or operate a Class II municipal waste combustion unit and if all stack tests for a given pollutant over 3 consecutive years show you comply with the emission limit. In that case, you are not required to conduct a stack test for that pollutant for the next 2 years. However, you shall conduct another stack test within 36 months of the anniversary date of the third consecutive stack test that shows you comply with the emission limit. Thereafter, you shall perform stack tests every 3rd year but no later than 36 months following the previous stack tests. If a stack test shows noncompliance with an emission limit, you shall conduct annual stack tests for that pollutant until all stack tests over 3 consecutive years show compliance with the emission limit for that pollutant. The provision applies to all pollutants subject to stack testing requirements: dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash.

2. You may test less often for dioxins/furans emissions if you own or operate a municipal waste combustion plant that meets the following 2 conditions. First, you have multiple municipal waste combustion units onsite that are subject to this section. Second, all those municipal waste combustion units have demonstrated levels of dioxins/furans emissions less than or equal to 7 nanograms per dry standard cubic meter, total mass, for 2 consecutive years. In that case, you may choose to conduct annual stack tests on only one municipal waste combustion unit per year at your plant. This provision only applies to stack testing for dioxins/furans emissions and is subject to the following 3 conditions:

a. You shall conduct the stack test no more than 13 months following a stack test on any municipal waste combustion unit subject to this section at your plant. Each year, you shall test a different municipal waste combustion unit subject to this section and shall test all municipal waste combustion units subject to this section in a sequence that you determine. Once you determine a testing sequence, it may not be changed without approval by the department.

b. If each annual stack test shows levels of dioxins/furans emissions less than or equal to 7 nanograms per dry standard cubic meter, total mass, you may continue stack tests on only one municipal waste combustion unit subject to this section per year.

c. If any annual stack test indicates levels of dioxins/furans emissions greater than 7 nanograms per dry standard cubic meter, total mass, you shall conduct subsequent annual stack tests on all municipal waste combustion units subject to this section at your plant.

2. For municipal waste combustion units with a design not based on heat input capacity, you shall use the maximum designed charging rate.

(e) Capacity of a batch municipal waste combustion unit. You shall calculate the capacity of a batch municipal waste combustion unit as the maximum design amount of municipal solid waste that can be charged per batch multiplied by the maximum number of batches that can be processed in 24 hours. Calculate the maximum number of batches by dividing 24 by the number of hours needed to process one batch. Retain fractional batches in the calculation. For example, if one batch requires 16 hours, the municipal waste combustion unit can combust 24/16, or 1.5 batches, in 24 hours.

(f) Quarterly carbon usage. If you use activated carbon to comply with the dioxins/furans or mercury limits, you shall calculate the required quarterly usage of carbon using the equation in subd.

1. for plant basis or the equation in subd. 2. for unit basis. 1. `Plant basis.'

See Image

where:

C is the required quarterly carbon usage for the plant in kilograms or pounds

fi is the required carbon feed rate for the municipal waste combustion unit in kilograms or pounds per hour. The required carbon feed rate is the average carbon feed rate during the most recent mercury or dioxins/furans stack tests, whichever has a higher feed rate.

hi is the number of hours the municipal waste combustion unit was in operation during the calendar quarter.

n is the number of municipal waste combustion units, i, located at your plant.

2. `Unit basis.'
