PM2.5 data indicates a consistent presence throughout the year, with no unhealthy days reported. The average PM2.5 concentration is low at 5.155 µg/m³. Ozone data is not available, with no ozone monitoring days or ozone-related rows recorded.

# 4. Highest PM2.5 dates

The highest PM2.5 concentrations occurred on the following dates:
- 2024-07-24 with an average of 20.702 µg/m³
- 2024-07-23 with an average of 20.215 µg/m³
- 2024-07-25 with an average of 13.833 µg/m³
- 2024-11-22 with an average of 13.905 µg/m³
- 2024-05-05 with an average of 13.417 µg/m³

# 5. Confounders and missing data

Potential confounders include wildfire smoke, regional transport, meteorology/wind direction, temperature inversion, agricultural dust, oil and gas activity, traffic/diesel corridors, monitor siting limitations, data completeness, and seasonal patterns. Missing data includes facility-level emissions, permit violation records, hospitalization data, wind/smoke data, causal models, and source apportionment.

# 6. What cannot be concluded

No conclusions can be drawn regarding causation, permit violations, enforcement priorities, compliance status, or health attribution. The evidence packet does not support such inferences.

# 7. Recommended next data pulls and policy addendum candidates

Further data pulls should include facility-level emissions, structured permit violation records, hospitalization data, wind and smoke data, and source apportionment analysis. Policy addendum candidates may include industrial activity monitoring, air quality impact assessments, and regional air quality coordination.
