(Silver Eagle), Minor, Davis County, FRS # UT00000049001100019 INSPECTION TYPE: State Electronic Data Report (SEDR) Review REVIEW DATE: February 7, 2024 SOURCE LOCATION: North Salt Lake/Davis County SOURCE CONTACT: Blaine Zwahlen, 435-319-6861 APPLICABLE REGULATIONS: Approval Order - DAQE-AN0101240030-16 – dated November 9, 2016 SOURCE INSPECTION EVALUATION: With the exception of sources that only monitor for opacity, quarterly report memoranda will only address the findings of the quarterly report. Approval Order and Title V permit conditions addressing continuous emission monitoring requirements will be addressed in Silver Eagle’s relative accuracy performance specification test review memorandum.

CURRENT RECOMMENDATIONS: All deviations appear to be a result of breakdown or process related problems that do not warrant issuing a violation. Silver Eagle was in compliance during this reporting period. No further enforcement actions should be taken. Silver Eagle’s NSPS monitoring system meets the performance standards of 40 CFR 60, Appendix B Performance Specifications. HIGH PRIORITY VIOLATOR (HPV): No RECOMMENDATION FOR NEXT INSPECTION: Check DAS for daily zero and span drift. Check the QC program to ensure that monitor drift is being tracked and that the source can identify excessive drift.
