NR 440.26(7)(j)3.c.c. Fresh feed sulfur content shall be calculated for each 8-hour period using the following equation:
where:
Sf is the fresh feed sulfur content expressed in percent by weight of fresh feed
n is the number of separate fresh feed streams charged directly to the riser or reactor of the fluid catalytic cracking unit
Qf is the total volumetric flow rate of fresh feed charged to the fluid catalytic cracking unit
Si is the fresh feed sulfur content expressed in percent by weight of fresh feed for the “ith” sampling location
Qi is the volumetric flow rate of fresh feed stream for the “ith” sampling location
NR 440.26(7)(j)4.4. Calculate a 7-day average (arithmetic mean) sulfur content of the fresh feed using all of the fresh feed sulfur content values obtained during 7 successive 24-hour periods.
NR 440.26(8)(8)Reporting and recordkeeping requirements.
NR 440.26(8)(a)(a) Each owner or operator subject to sub. (5) (b) shall notify the department of the specific provisions of sub. (5) (b) with which the owner or operator elects to comply. Notification shall be submitted with the notification of initial startup required by s. NR 440.07 (1) (c). If an owner or operator elects at a later date to comply with an alternative provision of sub. (5) (b), then the department shall be notified by the owner or operator in the report described in par. (c).
NR 440.26(8)(b)(b) Each owner or operator subject to sub. (5) (b) shall record and maintain the following information:
NR 440.26(8)(b)1.1. If complying with sub. (5) (b) 1.:
NR 440.26(8)(b)1.a.a. All data and calibrations from continuous monitoring systems located at the inlet and outlet to the control device, including the results of the daily drift tests and quarterly accuracy assessments required under Appendix F, Procedure 1 of 40 CFR part 60, incorporated by reference in s. NR 440.17;
NR 440.26(8)(b)1.b.b. Measurements obtained by supplemental sampling required under sub. (6) (a) 13. and 40 CFR 60.106 (k) for meeting minimum data requirements; and
NR 440.26(8)(b)1.c.c. The written procedures for the quality control program required by Appendix F, Procedure 1 of 40 CFR part 60, incorporated by reference in s. NR 440.17.
NR 440.26(8)(b)2.2. If complying with sub. (5) (b) 2., measurements obtained in the daily Method 8 testing, or those obtained by alternative measurement methods, if sub. (7) (i) 12. applies.
NR 440.26(8)(b)3.3. If complying with sub. (5) (b) 3., data obtained from the daily feed sulfur tests.
NR 440.26(8)(b)4.4. Each 7-day rolling average compliance determination.
NR 440.26(8)(c)(c) Each owner or operator subject to sub. (5) (b) shall submit a report except as provided by par. (d). The following information shall be contained in the report:
NR 440.26(8)(c)1.1. Any 7-day period during which:
NR 440.26(8)(c)1.a.a. The average percent reduction and average concentration of sulfur dioxide on a dry, O2-free basis in the gases discharged to the atmosphere from any fluid cracking unit catalyst regenerator for which the owner or operator seeks to comply with sub. (5) (b) 1. is below 90% and above 50 ppmv, as measured by the continuous monitoring system prescribed under sub. (6) (a) 8., or above 50 ppmv, as measured by the outlet continuous monitoring system prescribed under sub. (6) (a) 9. The average percent reduction and average sulfur dioxide concentration shall be determined using the procedures specified under sub. (7) (h);
NR 440.26(8)(c)1.b.b. The average emission rate of sulfur dioxide in the gases discharged to the atmosphere from any fluid catalytic cracking unit catalyst regenerator for which the owner or operator seeks to comply with sub. (5) (b) 2. exceeds 9.8 kg SOx per 1,000 kg coke burn-off, as measured by the daily testing prescribed under sub. (7) (i). The average emission rate shall be determined using the procedures specified under sub. (7) (i); and
NR 440.26(8)(c)1.c.c. The average sulfur content of the fresh feed for which the owner or operator seeks to comply with sub. (5) (b) 3. exceeds 0.30% by weight. The fresh feed sulfur content, a 7-day rolling average, shall be determined using the procedures specified under sub. (7) (j).
NR 440.26(8)(c)2.2. Any 30-day period in which the minimum data requirements specified in sub. (5) (d) are not obtained.
NR 440.26(8)(c)3.3. For each 7-day period during which an exceedance has occurred as defined in par. (c) 1. a. to c. and 2.:
NR 440.26(8)(c)3.a.a. The date that the exceedance occurred;
NR 440.26(8)(c)3.b.b. An explanation of the exceedance;
NR 440.26(8)(c)3.c.c. Whether the exceedance was concurrent with a startup, shutdown or malfunction of the fluid catalytic cracking unit or control system; and
NR 440.26(8)(c)3.d.d. A description of the corrective action taken, if any.
