NR 440.76(6)(c)2.2. When the certified chief facility operator and certified shift supervisor are offsite for more than 12 hours, but for 2 weeks or less, and no other certified operator is onsite, the provisionally certified control room operator may perform the required duties without notice to, or approval by, the department. However, you shall record the period when the certified chief facility operator and certified shift supervisor are offsite and include that information in the annual report as specified under sub. (13) (h) 12. NR 440.76(6)(c)3.3. When the certified chief facility operator and certified shift supervisor are offsite for more than 2 weeks, and no other certified operator is onsite, the provisionally certified control room operator may perform the required duties without approval by the department. However, you shall take the following 2 actions: NR 440.76(6)(c)3.a.a. Notify the department in writing. In the notice, state what caused the absence and what you are doing to ensure that a certified chief facility operator or certified shift supervisor is onsite. NR 440.76(6)(c)3.b.b. Submit a status report and corrective action summary to the department every 4 weeks following the initial notification. If the department notifies you that your status report or corrective action summary is disapproved, the municipal waste combustion unit may continue operation for 90 days, but then shall cease operation. If corrective actions are taken in the 90-day period such that the department withdraws the disapproval, municipal waste combustion unit operation may continue.

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. 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)(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)(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)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)(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)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.
