Air Quality Reports
The San Luis Obispo County Air Pollution Control District (APCD) prepares a variety of reports on air quality monitoring performed at various sites throughout the county, including annual reports summarizing air quality data collected for a given year; reports on special air quality monitoring studies conducted for a specific purpose; long-term air quality trend analyses; and mandated reports on our air quality monitoring network. The various reports are presented below.
Annual Report
The Annual Air Quality Report describes the network of air monitoring sites operated in the county for that calendar year (occasionally 2 years are combined); the different pollutants measured at each site; the state and federal health standards that must be met for each pollutant; the three highest concentrations measured for each pollutant at each site during that year; and trend charts presenting several years of concentration data for both ozone and particulate matter, the two pollutants of most concern in our county.
Current and historical Annual Air Quality Reports are available below1.

Since 2010, the District has been upgrading and standardizing our data compilation and analysis methods, including improvements to data accuracy by switching to electronic data tabulation rather than the manual count method used previously. A comprehensive review of the data presented in previous annual reports was also conducted to identify and correct any data discrepancies compared to current methods; this review revealed some tabulation errors in the pollutant trend charts presented in reports prior to 2010. Addenda have been added to the 1999-2009 Annual Reports to correct those errors; a detailed discussion in the 2008-2009 Annual Report and referenced in the other reports describes the specific errors corrected and some of the new data review and presentation protocols now in place.
Network Plan
The APCD has finished preparing the 2012 Ambient Air Monitoring Network Plan. The Network Plan provides a comprehensive description of our air pollution monitoring efforts along with a discussion of changes we anticipate over the next 18 months. The document is available in various formats to the public including downloadable files from this website and hardcopy reports available by request from our office. The public review period for this document will end on August 9, 2012 after which any changes will be incorporated prior to submittal to the USEPA and California Air Resources Board. Please submit any comments or suggestions related to this report to Karl Tupper or Jaime Contreras at the District office.
Network Assessment
The network assessment is a more detailed examination and assessment of the more technical aspects of the monitoring program performed every five years. The last network assessment was completed in 2010.
