Colorado has issued Action Day alerts on consecutive days this week for both ozone and fine particulates along the Front Range, and the guidance attached to them contains a request that has drawn skepticism from residents watching smoke roll in from fires hundreds of miles away.
The state advisory tells residents that even during periods of wildfire smoke, reducing personal emissions can help decrease ozone production. The alerts were issued by the Colorado Department of Public Health and Environment together with the Regional Air Quality Council, covering the Front Range Urban Corridor from Douglas County north to Larimer and Weld counties, including the Denver-Boulder area, Fort Collins and Greeley. The current alert runs until at least 4 p.m. Thursday.
