County - FRS # UT00000049000700030

INSPECTION TYPE: State Electronic Data Report (SEDR) Review

REVIEW DATE: April 25, 2024

SOURCE LOCATION: East Carbon/Emery County

SOURCE CONTACT: Rusty Netz, [phone] ext. 107

APPLICABLE
REGULATIONS: Title V Operating Permit
Permit Number: 700030005

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 Sunnyside’s relative accuracy performance
specification test review memorandum.

SOURCE INSPECTION
SUMMARY EVALUATION: Sunnyside maintains its CEMS as required in R307-170 and
40 CFR 60.13.

CURRENT
RECOMMENDATIONS: All deviations appear to be a result of breakdown or process
related problems that do not warrant issuing a violation. Periods
of excess emissions that were recorded by the CMS in service on
each point source during this reporting period are summarized in
the SEDR and described in Pivot Table 400 “Excess Emissions
Review.” Sunnyside was in compliance during this reporting
period. No further enforcement actions should be taken.
Sunnyside’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.
