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.

5
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.
