NR 440.77(8)(b)(b) By what date must I conduct the initial performance test? The initial performance test shall be conducted within 60 days after your CISWI unit reaches the charge rate at which it will operate, but no later than 180 days after its initial startup.

NR 440.77(9)(a)(a) How do I demonstrate continuous compliance with the emission limitations and the operating limits?

NR 440.77(9)(a)1.1. You shall conduct an annual performance test for particulate matter, hydrogen chloride and opacity for each CISWI unit as required under s. NR 440.08 to determine compliance with the emission limitations. The annual performance test shall be conducted using the test methods listed in Table 1 of this section and the procedures in sub. (7) (a).

NR 440.77(9)(a)2.2. You shall continuously monitor the operating parameters specified in sub. (6) (b) or established under sub. (6) (c). Operation above the established maximum or below the established minimum operating limits constitutes a deviation from the established operating limits. Three-hour rolling average values shall be used to determine compliance (except for baghouse leak detection system alarms) unless a different averaging period is established under sub. (6) (c). Operating limits do not apply during performance tests.

NR 440.77(9)(a)3.3. You shall only burn the same types of waste used to establish operating limits during the performance test.

NR 440.77(9)(b)(b) By what date must I conduct the annual performance test? You shall conduct annual performance tests for particulate matter, hydrogen chloride and opacity within 12 months following the initial performance test. Subsequent annual performance tests shall be conducted within 12 months following the previous one.

NR 440.77(9)(c)1.1. You may test less often for a given pollutant if you have test data for at least 3 years, and all performance tests for the pollutant (particulate matter, hydrogen chloride or opacity) over 3 consecutive years show that you comply with the emission limitation. In this case, you do not have to conduct a performance test for that pollutant for the next 2 years. You shall conduct a performance test during the 3rd year and no later than 36 months following the previous performance test.

NR 440.77(9)(c)2.2. If your CISWI unit continues to meet the emission limitation for particulate matter, hydrogen chloride or opacity, you may choose to conduct performance tests for these pollutants every 3rd year, but each test shall be within 36 months of the previous performance test.

NR 440.77(9)(c)3.3. If a performance test shows a deviation from an emission limitation for particulate matter, hydrogen chloride or opacity, you shall conduct annual performance tests for that pollutant until all performance tests over a 3-year period show compliance.

NR 440.77(9)(d)1.1. You may conduct a repeat performance test at any time to establish new values for the operating limits. The department may request a repeat performance test at any time.

NR 440.77(9)(d)2.2. You shall repeat the performance test if your feed stream is different than the feed streams used during any performance test used to demonstrate compliance.

NR 440.77(10)(a)1.1. If you are using a wet scrubber to comply with the emission limitation under sub. (6) (a), you shall install, calibrate to manufacturers’ specifications, maintain and operate devices (or establish methods) for monitoring the value of the operating parameters used to determine compliance with the operating limits listed in Table 2 of this section. These devices or methods shall measure and record the values for these operating parameters at the frequencies indicated in Table 2 of this section at all times except as specified in par. (b) 1.

NR 440.77(10)(a)2.2. If you use a fabric filter to comply with the requirements of this section, you shall install, calibrate, maintain and continuously operate a bag leak detection system as follows:

NR 440.77(10)(a)2.a.a. You shall install and operate a bag leak detection system for each exhaust stack of the fabric filter.

NR 440.77(10)(a)2.b.b. Each bag leak detection system shall be installed, operated, calibrated and maintained in a manner consistent with the manufacturer’s written specifications and recommendations.

NR 440.77(10)(a)2.c.c. The bag leak detection system shall be certified by the manufacturer to be capable of detecting particulate matter emissions at concentrations of 10 milligrams per actual cubic meter or less.

NR 440.77(10)(a)2.d.d. The bag leak detection system sensor shall provide output of relative or absolute particulate matter loadings.

NR 440.77(10)(a)2.e.e. The bag leak detection system shall be equipped with a device to continuously record the output signal from the sensor.

NR 440.77(10)(a)2.f.f. The bag leak detection system shall be equipped with an alarm system that will sound automatically when an increase in relative particulate matter emissions over a preset level is detected. The alarm shall be located where it is easily heard by plant operating personnel.

NR 440.77(10)(a)2.g.g. For positive pressure fabric filter systems, a bag leak detection system shall be installed in each baghouse compartment or cell. For negative pressure or induced air fabric filters, the bag leak detector shall be installed downstream of the fabric filter.

NR 440.77(10)(a)2.h.h. Where multiple detectors are required, the system’s instrumentation and alarm may be shared among detectors.

NR 440.77(10)(a)3.3. If you are using something other than a wet scrubber or fabric filter to comply with the emission limitations under sub. (6) (a), you shall install, calibrate to the manufacturers’ specifications and maintain and operate the equipment necessary to monitor compliance with the site-specific operating limits established using the procedures in sub. (6) (c).

NR 440.77(10)(b)1.1. Except for monitor malfunctions, associated repairs and required quality assurance or quality control activities (including, as applicable, calibration checks and required zero and span adjustments of the monitoring system) you shall conduct all monitoring at all times the CISWI unit is operating.
