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.
NR 440.76(10)(d)3.3. You shall obtain an oxygen or carbon dioxide measurement at the same time as your pollutant measurements to determine diluent gas levels, as specified in sub. (9) (b).
NR 440.76(10)(d)4.4. You shall use the equations in sub. (15) (a) to (c) to calculate emission levels at 7% oxygen, or an equivalent carbon dioxide basis, the percent reduction in potential hydrogen chloride emissions, and the percent reduction for mercury emissions. The individual test methods in Table 5 of this section shall be used for other required equations.
NR 440.76(10)(d)5.5. 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.
NR 440.76(10)(e)(e) May I conduct stack testing less often?
NR 440.76(10)(e)1.1. 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.
NR 440.76(10)(e)2.2. 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:
NR 440.76(10)(e)2.a.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.
NR 440.76(10)(e)2.b.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.
NR 440.76(10)(e)2.c.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. You may return to testing one municipal waste combustion unit subject to this section per year if you can demonstrate dioxins/furans emission levels less than or equal to 7 nanograms per dry standard cubic meter, total mass, for all municipal waste combustion units at your plant subject to this section for 2 consecutive years.
NR 440.76(10)(f)(f) May I deviate from the 13-month testing schedule if unforeseen circumstances arise? You may not deviate from the 13-month testing schedules specified in pars. (c) 2. and (e) 2. a. unless you apply to the department for an alternative schedule, and the department approves your request for alternate scheduling prior to the date on which you would otherwise have been required to conduct the next stack test.
NR 440.76(11)(11)Other monitoring requirements.
NR 440.76(11)(a)(a) Must I meet other requirements for continuous monitoring? You shall also monitor 3 operating parameters:
NR 440.76(11)(a)1.1. Load level of each municipal waste combustion unit.
NR 440.76(11)(a)2.2. Temperature of flue gases at the inlet of your particulate matter air pollution control device.
NR 440.76(11)(a)3.3. Carbon feed rate if activated carbon is used to control dioxins/furans or mercury emissions.
