What We're Doing about Ozone in Boulder County

Clean Air Challenge

Together with the Boulder County Clean Air Consortium (BCCAC), which is a group of community leaders in the private and public sectors who share a commitment to improving air quality in Boulder County, we sponsor the Clean Air Challenge each summer to reduce summer air pollution (ozone). In a typical year, the participants in the Clean Air Challenge reduced at least 124 pounds of ozone-forming emissions and 38 tons of carbon dioxide (the primary greenhouse gas contributing to global warming).

Ozone Action Plan

We played an active role in a recent rulemaking before the state Air Quality Control Commission. We:

  • Convened a coalition of local governments and environmental groups.
  • Developed emission reduction proposals.
  • Reviewed and provided testimony on strategies.
  • Created a compromise proposal with industry that led to the adoption of the most stringent strategy in the Ozone Action Plan.

Air Quality Monitoring

We work with the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division to monitor local levels of ozone and other air pollutants by:

  • Monitoring levels of various pollutants, including ozone. You can review the data from the South Boulder Creek ozone monitor located just south of Boulder along Colorado Highway 93.
  • Inspecting stationary sources of volatile organic compounds (VOCs), which contribute to ozone formation, to ensure compliance with state and federal air pollution regulations and permits.

Ozone & Air Toxics Study

In partnership with the University of Colorado at Boulder, we completed a Boulder County air toxics study in 2007-2008. The study revealed the movement and formation of ozone on both the eastern and western edges of Boulder County. The study measured:

  • Levels of VOCs, such as benzene, toluene, ethylbenzene, xylenes and hexane and carbonyls (e.g. formaldehyde, acetaldehyde, and acrolein).
  • Ozone levels in Boulder, Lyons, Longmont, and Niwot Ridge (in the mountains on the western edge of Boulder County).
