SOURCE INSPECTION
SUMMARY EVALUATION: Hunter 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.”
Hunter was in compliance during this reporting period. No further
enforcement actions should be taken.
Hunter’s NSPS monitoring system meets the performance standards of
40 CFR 60, Appendix B Performance Specifications.
Hunter’s 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.
Check the QC program to ensure that monitor drift is being tracked and
that the source can identify excessive drift.
