NR 440.26(6)(c)(c) The average coke burn-off rate (Mg (tons) per hour) and hours of operation shall be recorded daily for any fluid catalytic cracking unit catalyst regenerator subject to sub. (3), (4) or (5) (b) 2.
NR 440.26(6)(d)(d) For any fluid catalytic cracking unit catalyst regenerator under sub. (3) that uses an incinerator-waste heat boiler to combust the exhaust gases from the catalyst regenerator, the owner or operator shall record daily the rate of combustion of liquid or solid fossil-fuels and the hours of operation during which liquid or solid fossil-fuels are combusted in the incinerator-waste heater boiler.
NR 440.26(6)(e)(e) For the purpose of reports under s. NR 440.07 (3), periods of excess emissions that shall be determined and reported are defined as follows:
NR 440.26 NoteNote: All averages, except for opacity, shall be determined as the arithmetic average of the applicable 1-hour averages, e.g., the rolling 3-hour average shall be determined as the arithmetic average of 3 contiguous 1-hour averages.
NR 440.26(6)(e)1.1. Opacity. All 1-hour periods that contain 2 or more 6-minute periods during which the average opacity as measured by the continuous monitoring system under par. (a) 1. exceeds 30%.
NR 440.26(6)(e)2.2. Carbon monoxide. All 1-hour periods during which the average CO concentration as measured by the CO continuous monitoring system under par. (a) 2. exceeds 500 ppm.
NR 440.26(6)(e)3.3. Sulfur dioxide from fuel gas combustion.
NR 440.26(6)(e)3.a.a. All rolling 3-hour periods during which the average concentration of SO2 as measured by the SO2 continuous monitoring system under par. (a) 3. exceeds 20 ppm (dry basis, zero percent excess air); or
NR 440.26(6)(e)3.b.b. All rolling 3-hour periods during which the average concentration of H2S as measured by the H2S continuous monitoring system under par. (a) 4. exceeds 230 mg/dscm (0.10 gr/dscf).
NR 440.26(6)(e)4.4. Sulfur dioxide from Claus sulfur recovery plants.
NR 440.26(6)(e)4.a.a. All 12-hour periods during which the average concentration of SO2 as measured by the SO2 continuous monitoring system under par. (a) 5. exceeds 250 ppm (dry basis, zero percent excess air); or
NR 440.26(6)(e)4.b.b. All 12-hour periods during which the average concentration of reduced sulfur (as SO2) as measured by the reduced sulfur continuous monitoring system under par. (a) 6. exceeds 300 ppm; or
NR 440.26(6)(e)4.c.c. All 12-hour periods during which the average concentration of SO2 as measured by the SO2 continuous monitoring system under par. (a) 7. exceeds 250 ppm (dry basis, zero percent excess air).
NR 440.26(7)(7)Test methods and procedures.
NR 440.26(7)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2).
NR 440.26(7)(b)(b)
NR 440.26(7)(b)1.1. The emission rate (E) of PM shall be computed for each run using the following equation:
=
where:
E is the emission rate of PM, kg/Mg (lb/ton) of coke burn-off
cs is the concentration of PM, g/dscm (gr/dscf)
Qsd is the volumetric flow rate of exhaust gas, dscm/hr (dscf/hr)
Rc is the coke burn-off rate, Mg/hr (ton/hr) coke
K is a conversion factor, 1,000 g/kg (7000 gr/lb)
NR 440.26(7)(b)2.2. Method 5B or 5F shall be used to determine particulate matter emissions and associated moisture content from affected facilities without wet FGD systems; only Method 5B shall be used after wet FGD systems. The sampling time for each run shall be at least 60 minutes and the sampling time for each run shall be at least 0.015 dscm/min (0.53 dscf/min) except that shorter sampling times may be approved by the department when process variables or other factors preclude sampling for at least 60 minutes.
NR 440.26(7)(b)3.3. The coke burn-off rate (Rc) shall be computed for each run using the following equation:
