Note: Review and validation of this data is conducted by the CO Department of Public Health and Environment (CDPHE) and can take 8 - 12 weeks after the quarter ends. Accordingly, current performance is based on the prior quarter's results.
- This is a quarterly metric.
- The AQI did not meet the target.
- The AQI represents a combination of impacts from particulate matter and ground levels ozone concentrations.
- Higher ozone concentrations are generally observed in summer months, and the Northern Front Range region is in violation of Federal health-based ozone standards.
- A record 23 days were considered unhealthy for sensitive groups for ozone, with 2 days unhealthy for particulate matter.
- Ozone formation is influenced by many factors including intensity and hours of sunlight, stability of the atmosphere, and sources of air pollutants.
- Particulate levels were affected by large regional wildfires.
- Ozone and particulate matter are regional issues.
- Continued violation of Federal standards is expected to lead to tighter controls for contributing emissions.
- Enhanced regulatory efforts may include impacts to personal vehicle use, such as increased inspection and maintenance programs.
Local efforts to improve air quality include:
- Providing education and outreach to increase awareness about the health impacts of high pollution days, including a data monitoring website (see fcgov.com/airquality)
- Partnering with the Regional Air Quality Council (RAQC) to provide outreach regarding high ozone days
- Restrictions on outdoor solid fuel burning in residential areas
- Transportation planning efforts to reduce vehicles emissions, such as promotion of alternative transportation options and anti-idling campaigns
- Regional and local efforts to reduce emissions from oil and gas development.
- Incentive programs to replace gas powered lawn and garden equipment with electric options
