NR 440.26(7)(i)(i) For the purpose of determining compliance with sub. (5) (b) 2., the following reference methods from 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17, and calculation procedures shall be used except as provided in subd. 12.:
NR 440.26(7)(i)1.1. One 3-hour test shall be performed each day.
NR 440.26(7)(i)2.2. For gases released to the atmosphere from the fluid catalytic cracking unit catalyst regenerator:
NR 440.26(7)(i)2.a.a. Method 8 as modified in subd. 3. for moisture content and for the concentration of sulfur oxides calculated as sulfur dioxide.
NR 440.26(7)(i)2.b.b. Method 1 for sample and velocity traverses.
NR 440.26(7)(i)2.c.c. Method 2 calculation procedures, data obtained from Methods 3 and 8, for velocity and volumetric flow rate.
NR 440.26(7)(i)2.d.d. Method 3 for gas analysis.
NR 440.26(7)(i)3.3. Method 8 shall be modified by the insertion of a heated glass fiber filter between the probe and first impinger. The probe liner and glass fiber filter temperature shall be maintained above 160°C (320°F). The isopropanol impinger shall be eliminated. Sample recovery procedures described in Method 8 for container No. 1 shall be eliminated. The heated glass fiber filter also shall be excluded; however, rinsing of all connecting glassware after the heated glass fiber filter shall be retained and included in container No. 2. Sampled volume shall be at least 1 dscm.
NR 440.26(7)(i)4.4. For Method 3, the integrated sampling technique shall be used.
NR 440.26(7)(i)5.5. Sampling time for each run shall be at least 3 hours.
NR 440.26(7)(i)6.6. All testing shall be performed at the same location. Where the gases discharged by the fluid catalytic cracking unit catalyst regenerator pass through an incinerator-waste heat boiler in which auxiliary or supplemental gaseous, liquid or solid fossil fuel is burned, testing shall be conducted at a point between the regenerator outlet and the incinerator-waste heat boiler. An alternative sampling location after the waste heat boiler may be used if alternative coke burn-off rate equations, and, if requested, auxiliary/supplemental fuel SOx credits, have been submitted to and approved by the department prior to sampling.
NR 440.26(7)(i)7.7. Coke burn-off rate shall be determined using the procedures specified under par. (b) 3., unless subd. 6. applies.
NR 440.26(7)(i)8.8. Calculate the concentration of sulfur oxides as sulfur dioxide using equation 8-3 in Section 6.5 of Method 8 to calculate and report the total concentration of sulfur oxides as sulfur dioxide
.
NR 440.26(7)(i)9.9. Sulfur oxides emission rate calculated as sulfur dioxide shall be determined for each test run by the following equation:
=
where:
is the sulfur oxides emission rate calculated as sulfur dioxide, kg/hr (lb/hr)
is the sulfur oxides emission concentration calculated as sulfur dioxide, g/dscm (gr/dscf)
Qsd is the dry volumetric stack gas flow rate corrected to standard conditions, dscm/hr (dscf/hr)
K is a conversion factor, 1,000 g/kg (7,000 gr/lb)
NR 440.26(7)(i)10.10. Sulfur oxides emissions calculated as sulfur dioxide shall be determined for each test run by the following equation:
where:
is the sulfur oxides emissions calculated as kg sulfur dioxide per Mg (lb/ton) coke burn-off
