DEVIATIONS: 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.”

SUMMARY EVALUATION: Lake Side maintains its CEMS as required in R307-170 and
40 CFR 60.13.

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

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.
