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.
