The Colorado Department of Public Health on Wednesday issued indoor burning restrictions for the Denver metro area because of poor visibility standards expected Thursday for the second consecutive day.

The “Action Day for Visibility” applies to the seven-county Denver metro area that includes Boulder and means that indoor wood-burning is prohibited except for certain approved devices or in homes where burning is the primary source of heat and an exemption letter has been issued, according to a news release.

The CDPHE issued the same advisory on Tuesday for Wednesday. The latest action day will continue until at least 4 p.m. Thursday because limited atmospheric mixing and ventilation will result in poor visibility.

The state health department looks at ozone, fine particulate matter, carbon monoxide, nitrogen dioxide and visibility when determining air quality for the Front Range. With the exception of visibility, the other categories are expected to be in good condition Thursday. However, fine particulate matter might dip into the moderate range.
