On Monday July 15 NWS offices in Colorado will begin officially issuing Air Quality Alerts in partnership with Colorado Department of Public Health & Environment (CDPHE). CDPHE's Air Pollution Control Division, in tandem with Colorado's Air Quality Control Commission (AQCC), are responsible for the protection of public health and the improvement of air quality in the state. When CDPHE issues an Ozone Action Day or other alert, the NWS will relay that information to the public via our Air Quality Alert. Check our website at www.weather.gov/bou and look on the map for the affected regions.
