Attainment Status

As the chart below shows, Yolo-Solano currently meets the EPA’s health standards for five of those pollutants. For the other two — ground-level ozone and fine particulate pollution — Yolo-Solano is considered to be a part of a regional non-attainment area.


We also have a more detailed table showing our attainment status for the criteria pollutants along with the standards.

Because our air quality does not meet federal standards for ozone or fine particulates, Yolo-Solano AQMD must complete detailed plans to show how those standards will be reached by the EPA’s deadlines.  To see more on the planning efforts, see the following pages:
