Pursuant to 40 CFR 60 NSPS Subpart Ja and 40 CFR 60.7(c), FIF Sinclair Woods Cross Refining LLC,
I{FSWCR, is submitting this periodic report of excess emissions in accordance with 40 CFR 60.108a(d).
Additionally, fmSWCR maintains records of discharges exceeding certain amounts in accordance with 40
CFR 60.108a(cX6). 40 CFR 108a(c)(6) requires the owner/operator to maintain records of releases that
exceed 500 lbs SOz in arry 24-hour period from any affected flare, discharges greater than 500 lbs SOz in
excess of the allowable limits from a fuel gas combustion device or sulfur recovery plant and discharges
to an affected flare in excess of 500,000 scf above baseline in any Z4-hour period. These records are to be
included in periodic excess emissions reports pursuant to 40 CFR 60.108a(d)(5). For the period of July 1,
2022 tbrottgh December 31,2022 the records maintained include the following:
Additional requirements of reporting excess emissions as required in 40 CFR 60.7(c) and 40 CFR 60.108a
were reported in quarterly CEMS reports dated 1 0/1 8 12022 and 1127 12023 .
