About CALs

Community Air-Quality Levels (CALs) are used to describe air quality in terms of how harmful the level of particulate matter (PM) pollution in the air is to human health. The CALs are derived using similar methods as EPA’s Air Quality Index (AQI).

You should use both IVAN Air Monitoring and government air data to understand the air quality levels around you. When comparing health recommendations from both sources, you should follow the most health protective recommendation.

*Sensitive groups include children, teens, older adults, pregnant women, and people with heart, lung, or other chronic diseases

Report an air problem

If you are experiencing an emergency, call 9-1-1.

Step 1. Report to the San Joaquin Valley Air Pollution Control District.

Call 1-800-870-1037 as soon as you notice a problem with air quality. Their website lists what information to provide in order to support their investigations. It also describes what to expect when you submit a complaint.

Step 2. Report on IVAN.

After contacting the SJVAPCD, we recommend that you also submit a record of the problem here on IVAN FRESNO, including a note that SJVAPCD has been contacted. This ensures that the Environmental Justice Task Force is aware of the complaint and that the complaint is documented on the IVAN FRESNO website.
