SUMMARY EVALUATION: Huntington 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. Huntington was in
compliance during this reporting period. No further compliance action is
recommended.
Huntington’s NSPS monitoring system meets the performance standards
of 40 CFR 60, Appendix B Performance Specifications. Huntington’s
acid rain monitoring system meets the performance standards of 40 CFR
75 Acid Rain Performance Specifications.
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.”
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 that
the source can identify excessive drift.
