SOURCE INSPECTION
SUMMARY EVALUATION: Holcim is maintaining its COMS as required in R307-170 and 40
CFR 603. Cylinder gas audits were conducted as required.

CURRENT
RECOMMENDATIONS: Holcim experienced multiple FID monitor failures warranting
replacement of the unit. Several options including rental units
were used until a permanent replacement unit could be procured
on October 6, 2024. Sufficient explanation of the events leading
up to the monitor failure and replacement was included in the
appendix to the cover letter.

All other 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.” Holcim was in compliance during
this reporting period. No further enforcement actions should be
taken. Holcim’s NSPS monitoring system meets the
performance standards of 40 CFR 60, Appendix B 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.
