Air Toxics Program


Air toxics reduction efforts are coordinated by The Planning and Policy Program. Activities of the program range from reviewing and commenting on national toxics reduction efforts to assisting local communities in addressing air toxics.

 

Division successes to date include air toxics monitoring, inventorying and inspection of air toxics sources, assistance to city and county agencies, stakeholder involvement, working with other department programs (Water Quality, Environmental Epidemiology) and collaborating with the US Environmental Protection Agency (EPA).

 

Air toxics are also referred to as hazardous air pollutants.

 

While all pollutants are toxic, EPA lists 188 air toxics as distinct from "criteria pollutants." Criteria pollutants include ozone, carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter and lead.

 

The Air Pollution Control Division conducts several activities that control or prevent air toxics, including:

 

  • Automobile inspection and maintenance
  • Clean Fuel and alternative fuel use
  • Ozone reduction awareness efforts to reduce volatile organic chemicals
  • Chlorofluorocarbon reduction and phase-out
  • Air pollution control technology requirements for industry
  • Pollution Prevention efforts in industries and communities statewide

 

The air division also conducts activities to measure and analyze hazardous air pollutants in Colorado. These include:

 

  • Hazardous air pollutant inventory development, such as databases of stationary source emissions and the Colorado Diesel Exhaust Emissions Study (2003)
  • Pollution modeling, which estimates emissions of air toxics, their transport in air and their effect on ambient (outdoor) air quality
  • Air monitoring, to measure the quantity of specific pollutants in the air.
  • Risk assessment of inhalation exposure (with the Disease Control and Environmental Epidemiology Division)
