Monitoring & Reporting Air Quality

Keeping an eye on air quality in SLO County

Keeping a close watch on all air quality conditions throughout SLO County with our network of monitoring stations.

As stewards of healthful air supporting a healthy environment, part of the APCD’s mission is to promote community and individual responsibility for air quality.  The APCD keeps a close watch on all air quality conditions throughout SLO County with our network of monitoring stations. The data collected is then used to pinpoint where the air quality stands on the Air Quality Index (AQI) which is an index for reporting daily air quality.

The AQI tells you how clean or polluted your air is and what associated health effects might be a concern for you and is a standardized indicator of the air quality in a given location. The AQI categories have been assigned specific colors to help individuals easily understand the impact of air pollution. For example, the color orange means that conditions are “unhealthy for sensitive groups,” while green means that conditions are “good.” Each color represents a different level of health concern, with six total health concern levels.

The APCD also implements a number of programs to protect the general public against toxic air contaminants. Through the California Environmental Quality Act, the APCD reviews development projects to assess the potential air quality impacts. If a project has the potential to expose sensitive receptors then the APCD will request modifications to the project to protect those individuals. Another very successful program to reduce toxic air emissions is the Lower Emission School Bus Program (LESBP). The LESBP is intended to reduce school children's exposure to diesel particulate matter by providing funding to the school to replace and retrofit old school buses. Over $2 million has been allocated to San Luis Obispo County as part of this program.
