If you have submitted a written request and received permission with a burner identification number, please adhere to the instructions below. The Department will be working hard all winter to assess dispersion conditions and expected air quality in your area, and identify a timeframe that will minimize the impacts of your proposed burns to air quality.
- Please check this website often. It will be updated Monday through Friday, excluding holidays, by 5:00 pm. Burning “windows of opportunity” are infrequent and forecasts are subject to change.
- Determine if your assigned wintertime burn identification number is listed as having a possible “window of opportunity” on a given day. If so, call the Department's Open Burning Program Permitter Doug Kuenzli at 444-4267 at least 24 hours prior to the proposed date to create a burn plan. Please only call between 8:00 am-4:00 pm.
- Notify local fire control authorities prior to igniting your burn.
- At the completion of your burn, call the meteorologist to note the accomplishment achieved and indicate whether any future service will be required.
Thank you for working with the Air Resources Management Bureau to accomplish your burn.
