MEMORANDUM

TO: FILE – PACIFICORP – Currant Creek Power Plant

THROUGH: Harold Burge, Major Source Compliance Section Manager

FROM: Rob Leishman, Environmental Scientist

DATE: January 21, 2025

SUBJECT: PacifiCorp – Currant Creek Power Plant (Currant Creek), Major, NSPS, HAPs, Title IV,
Juab County, FRS # UT00000049002300026
INSPECTION TYPE: State Electronic Data Report (SEDR) Review

REVIEW DATE: January 21, 2025

SOURCE LOCATION: Near Mona Reservoir/Juab County

SOURCE CONTACT: David Blackburn – 435-623-3816

APPLICABLE
REGULATIONS: Approval Order DAQE-AN12524009-15 dated January 23, 2015 - New Source
Performance Standards (NSPS) Subparts A, Da, Dc, and GG, applies to this
source.

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 Currant Creek’s relative accuracy
performance specification test review memorandum.

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

CURRENT
RECOMMENDATIONS: All other 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.” Currant Creek was in compliance during this
reporting period. No further enforcement action is recommended.

Currant Creek’s NSPS monitoring system meets the performance standards of
40 CFR 60, Appendix B Performance Specifications.

Currant Creek’s acid rain monitoring system meets the performance standards
of 40 CFR 75 Acid Rain Performance Specifications.

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.
