Other high PM2.5 days include July 24, 2024, with an average of 24.74 µg/m³ and a maximum AQI of 80, and October 6, 2024, with an average of 20.00 µg/m³ and a maximum AQI of 71.

# 5. Confounders and missing data

Potential confounders include wildfire smoke, regional transport, meteorology, temperature inversion, agricultural dust, oil and gas activity, traffic, and monitor siting limitations. Missing data includes facility-level emissions, permit violation records, hospitalization data, wind and smoke data, and no causal model or source apportionment.

# 6. What cannot be concluded

No causation, permit violation, enforcement priority, compliance status, or health attribution can be concluded from this evidence packet. The data does not support conclusions about the sources of air pollution or their health impacts.

# 7. Recommended next data pulls and policy addendum candidates

Additional data pulls should include facility-level emissions, permit violation records, hospitalization data, and wind/smoke data. Policy addendums could focus on monitoring improvements, industrial activity assessments, and regional air quality collaboration.
