  1. Radon

Radon is a colorless, odorless radioactive gas that forms as a result of the natural decay of uranium underground. This Radon Information Sheet (PDF) explains more. According to the Environmental Protection Agency (EPA), radon is the number one cause of lung cancer among non-smokers. 

The only way to know if your home has high radon is to test. Free test kits are available to City of Aspen residents by filling out this online mail order form. After you submit a mail order form, a kit will be mailed to your home. Kits are not available for pick-up through the City of Aspen offices. 

If your home tests high for radon, it is important to install a mitigation system to reduce your risk of lung cancer. A list of certified mitigation contractors and assistance for low-income households can be found here.

  2. Idling and Smoking Vehicles
  3. Restaurant Grills

Aspen and Pitkin County regulate the number and type of fireplaces and woodstoves that can be installed in any building.  

Building permit applicants must file a fireplace / woodstove registration with the City of Aspen Building Department before the permit is issued.  

The device must be on the Colorado Certified Residential Burning Devices or EPA Certified Residential Burning Devices list.
