40 C.F.R. § 60.106
(h)
For the purpose of determining compliance with
§ 60.104(b)(1), the following calculation procedures shall be used:
(1)
Calculate each 1-hour average concentration (dry, zero percent oxygen, ppmv) of sulfur dioxide at both the inlet and the outlet to the add-on control device as specified in
§ 60.13(h). These calculations are made using the emission data collected under
§ 60.105(a).
(2)
Calculate a 7-day average (arithmetic mean) concentration of sulfur dioxide for the inlet and for the outlet to the add-on control device using all of the 1-hour average concentration values obtained during seven successive 24-hour periods.
(3)
Calculate the 7-day average percent reduction using the following equation—
(4)
Outlet concentrations of sulfur dioxide from the add-on control device for compliance with the 50 ppmv standard, reported on a dry, O2-free basis, shall be calculated using the procedures outlined in §
60.106(h)(1) and
(2) above, but for the outlet monitor only.
(5)
If supplemental sampling data are used for determining the 7-day averages under
paragraph (h) of this section and such data are not hourly averages, then the value obtained for each supplemental sample shall be assumed to represent the hourly average for each hour over which the sample was obtained.
(6)
For the purpose of adjusting pollutant concentrations to zero percent oxygen, the following equation shall be used:
(i)
For the purpose of determining compliance with
§ 60.104(b)(2), the following reference methods and calculation procedures shall be used except as provided in paragraph (i)(12) of this section:
(1)
One 3-hour test shall be performed each day.
(2)
For gases released to the atmosphere from the fluid catalytic cracking unit catalyst regenerator—
(i)
Method 8 as modified in
§ 60.106(i)(3) for moisture content and for the concentration of sulfur oxides calculated as sulfur dioxide,
(ii)
Method 1 for sample and velocity traverses,
(iii)
Method 2 calculation procedures (data obtained from Methods 3 and 8) for velocity and volumetric flow rate, and
(iv)
Method 3 for gas analysis.
(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.
(4)
For Method 3, the integrated sampling technique shall be used.
(5)
Sampling time for each run shall be at least 3 hours.
(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 Administrator prior to sampling.
(7)
Coke burn-off rate shall be determined using the procedures specified under
paragraph (b)(3) of this section, unless paragraph (i)(6) of this section applies.
(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 (Cso x).
(9)
Sulfur oxides emission rate calculated as sulfur dioxide shall be determined for each test run by the following equation:
(10)
Sulfur oxides emissions calculated as sulfur dioxide shall be determined for each test run by the following equation:
(11)
Calculate the 7-day average sulfur oxides emission rate as sulfur dioxide per Mg (ton) of coke burn-off by dividing the sum of the individual daily rates by the number of daily rates summed.
(12)
An owner or operator may, upon approval by the Administrator, use an alternative method for determining compliance with
§ 60.104(b)(2), as provided in
§ 60.8(b). Any requests for approval must include data to demonstrate to the Administrator that the alternative method would produce results adequate for the determination of compliance.
