SOURCE INSPECTION
SUMMARY EVALUATION: Graymont is maintaining its COMS 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.”

Graymont was in compliance during this reporting period. No
further enforcement actions should be taken. Graymont’s NSPS
monitoring system meets the performance standards of
40 CFR 60, Appendix B Performance Specification 1.

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.

ATTACHMENT: Excel spreadsheet review.
