SOURCE INSPECTION
SUMMARY EVALUATION: St. George City Power’s Millcreek Turbine 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.”
St. George City Power’s Millcreek Turbine was in compliance during
this reporting period. The monitoring system meets the performance
standards of 40 CFR 60, Appendix B Performance Specifications. No
further enforcement actions are recommended.
St. George City Power’s Millcreek Turbine acid rain monitoring system
meets the performance standards of 40 CFR 75 Acid Rain Performance
Specifications.
HIGH PRIORITY
VIOLATOR (HPV): No
RECOMMENDATION
FOR NEXT INSPECTION: Check DAS for daily zero and span drift.
