RECOMMENDATIONS: All deviations appear to be a result of breakdown or process related problems that do not warrant issuing a violation. Lake Side was in compliance during this reporting period. No further enforcement actions should be taken. Lake Side’s NSPS monitoring system meets the performance standards of 40 CFR 60, Appendix B Performance Specifications. Lake Side’s acid rain monitoring system meets the performance standards of 40 CFR 75 Acid Rain Performance Specifications. HPV: No 6 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.
