Air Quality & Your Health  

Visit our website to find out more information on how air quality can affect your health. You can also pick up the series of brochures for this campaign at several local medical offices, fitness facilities, and the APCD and Public Health offices. 


Campfire Etiquette
Follow these clean burning tips to protect yourself and fellow campers from the harmful health effects of wood smoke! 

  • Don't smoke your neighbors out. Smoke from camp fires is a common source of outdoor air pollution. Be careful not to build your campfire too close to your neighbors or homes nearby. Not everyone appreciates a campfire - especially those with allergies or health issues.
  • Before you strike the match, make sure that campfires are in fact allowed on your site. 
  • Keep your campfire small.
  • Burn only "seasoned" and dry firewood.
  • Don't Burn: garbage, plastics, Styrofoam, rubber, waste solvent, paint, oil, treated wood, particle board, plywood, driftwood, coal and charcoal, and colored or glossy paper. They can produce noxious, corrosive smoke and fumes which may be toxic to your family and pets.
  • Once you are done with the fire, ensure it is put out completely. A smoldering pile of ash may disrupt the sleep of many in your vicinity. You may not be very popular in the morning!

Air Quality Trends Report

Since 1970, air quality monitoring has been conducted in San Luis Obispo County. As shown in the report linked below, significant improvements in air quality have been observed in most areas of the county over the past 20 years, despite significant increases in population and vehicle miles traveled during that period. On March 27, the APCD Board received the 1991 - 2011 Air Quality Trends Report that evaluated ozone and particulate matter measurements countywide. 
To read more about the detailed trends analysis, please visit the links below. 

Letter to ARB Regarding Ag Tractor Regulation
At its March meeting, the APCD Board voted to send a letter to the California Air Resources Board (ARB) requesting an exemption from the proposed State Regulation on In-Use Mobile Agricultural Equipment. 

The proposed regulation is the result of the State's commitment in the 2007 State Implementation Plan (SIP) to achieve emission reductions necessary to bring the San Joaquin Valley into attainment with the federal ozone standard through regulation of mobile agricultural equipment.

APCD staff believes emission reductions from mobile agriculture equipment that operate in SLO County will not assist the San Joaquin Valley in meeting their clean air requirements. The APCD recognizes the significant hardship such a regulation could put on our local economy in the near future. In support of this position, the Board sent a letter to ARB requesting an exemption for SLO County from upcoming requirements for existing mobile agricultural equipment. 

Change to the Air Quality Index Scale


In December 2012, the U. S. Environmental Protection Agency (EPA) lowered the primary annual PM2.5 standard to 12.0 μg/m3 to further protect public health. EPA also modified the AQI scale to incorporate the new standard. 


The AQI scale has four categories that best represent local air quality conditions: Good, Moderate, Unhealthy for Sensitive Groups, and Unhealthy.  The upper end of the range for the "Good" AQI category (an index value of 50) will now be reached when PM2.5 concentrations hit 12.0 μg/m3, the level of the new annual standard. The upper end of the "Moderate" category (100 AQI) will remain the same and is set at the level of the 24-hour PM2.5 standard (35 μg/m3). 


The new scale took effect on March 18, 2013. This new scale will likely result in an increase in the number of air quality days in SLO County reported as Moderate.  It is important to note that the general air quality in the county is expected to remain the same - the AQI scale is changing, not the local air quality conditions.
