NR 440.76(8)(b)(b) What emission limits must I meet and by when? You shall meet the emission limits specified in Tables 1 and 2 of this section. You shall meet the limits 60 days after your municipal waste combustion unit reaches the maximum load level but no later than 180 days after its initial startup. NR 440.76(8)(c)(c) What happens to the emission limits during periods of startup, shutdown and malfunction? NR 440.76(8)(c)1.1. The emission limits of this section apply at all times except during periods of municipal waste combustion unit startup, shutdown or malfunction. NR 440.76(8)(c)2.2. Each startup, shutdown or malfunction may not last for longer than 3 hours. NR 440.76(8)(c)3.3. A maximum of 3 hours of test data may be dismissed from compliance calculations during periods of startup, shutdown or malfunction. NR 440.76(8)(c)4.4. During startup, shutdown or malfunction periods longer than 3 hours, emissions data cannot be discarded from compliance calculations and all provisions under s. NR 440.11 (4) apply. NR 440.76(9)(a)(a) What types of continuous emission monitoring must I perform? To continuously monitor emissions, you shall perform the following 4 tasks: NR 440.76(9)(a)1.1. Install continuous emission monitoring systems for certain gaseous pollutants. NR 440.76(9)(a)2.2. Make sure your continuous emission monitoring systems are operating correctly. NR 440.76(9)(b)(b) What continuous emission monitoring systems must I install for gaseous pollutants? NR 440.76(9)(b)1.1. You shall install, calibrate, maintain and operate continuous emission monitoring systems for oxygen or carbon dioxide, sulfur dioxide and carbon monoxide. If you operate a Class I municipal waste combustion unit, you shall also install, calibrate, maintain and operate a continuous emission monitoring system for nitrogen oxides. You shall install the continuous emission monitoring systems for sulfur dioxide, nitrogen oxides and oxygen or carbon dioxide at the outlet of the air pollution control device. NR 440.76(9)(b)2.2. You shall install, evaluate and operate each continuous emission monitoring system according to the monitoring requirements in s. NR 440.13. NR 440.76(9)(b)3.3. You shall monitor the oxygen or carbon dioxide concentration at each location where you monitor sulfur dioxide and carbon monoxide. Additionally, if you operate a Class I municipal waste combustion unit, you shall also monitor the oxygen or carbon dioxide concentration at the location where you monitor nitrogen oxides. NR 440.76(9)(b)4.4. You may choose to monitor carbon dioxide instead of oxygen as a diluent gas. If you choose to monitor carbon dioxide, then an oxygen monitor is not required, and you shall follow the requirements in par. (g). NR 440.76(9)(b)5.5. If you choose to demonstrate compliance by monitoring the percent reduction of sulfur dioxide, you shall also install continuous emission monitoring systems for sulfur dioxide and oxygen or carbon dioxide at the inlet of the air pollution control device. NR 440.76(9)(b)6.6. If you prefer to use an alternative sulfur dioxide monitoring method, such as parametric monitoring, or cannot monitor emissions at the inlet of the air pollution control device to determine percent reduction, you may apply to the department for approval to use an alternative monitoring method under s. NR 440.13 (9). NR 440.76(9)(c)(c) How are the data from the continuous emission monitoring systems used? You shall use data from the continuous emission monitoring systems for sulfur dioxide, nitrogen oxides and carbon monoxide to demonstrate continuous compliance with the emission limits specified in Tables 1 and 2 of this section. To demonstrate compliance for dioxins/furans, cadmium, lead, mercury, particulate matter, opacity, hydrogen chloride and fugitive ash, you shall meet sub. (10) (b). NR 440.76(9)(d)(d) How do I make sure my continuous emission monitoring systems are operating correctly? NR 440.76(9)(d)1.1. You shall conduct initial, daily, quarterly and annual evaluations of your continuous emission monitoring systems that measure oxygen or carbon dioxide, sulfur dioxide, nitrogen oxides (for Class I municipal waste combustion units only) and carbon monoxide. NR 440.76(9)(d)2.2. You shall complete your initial evaluation of the continuous emission monitoring systems 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(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.
