Update: 2021-22 MDUSD Action Plan for AQI Ratings based on school zip code
Posted 8/20/21

Based on the fluctuating Air Quality Index due to recent wildfires, the Mt. Diablo Unified School District has created an "action plan" that includes possible restrictions to school activities to protect the health of staff and students.

The district is using the Air Quality Index as reported in each individual school's zip code based on AirNow.Gov data.
