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 Power Plant 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.
