Title V Deviation Log
Log deviations as they happen with cause, corrective action, and prompt-report dates. Entries group by your permit's reporting periods and export for the semiannual report.
“What deviated this reporting period, why, and did we report it?”
Reporting periods
Set these to match the reporting periods in your permit. The permit defines what counts as a deviation and which ones need prompt reporting.

How this works
Why log deviations as they happen
- Title V permits require prompt reporting of deviations, with the probable cause and the corrective actions or preventive measures taken (40 CFR 70.6(a)(3)(iii)(B)). The permit defines “prompt.”
- Periodic monitoring reports must clearly identify every deviation in the period (40 CFR 70.6(a)(3)(iii)(A)), and the annual compliance certification draws on the same record (40 CFR 70.6(c)(5)).
- Details are easiest to capture the day they happen: times, the condition affected, what operators saw, and what was done.
Using the log
- Set the report cycle and the month a period starts so entries group the way your permit's reports do.
- Record the prompt report date when one is sent, so the periodic report can reference it.
- Export the CSV or print a period when drafting the report. The log is an AirPermitHub template, not an agency form; use your agency's report forms where required.
- Entries stay in this browser. Export regularly and keep the file with your compliance records.
