Requests to limit driving of non- ZEV vehicles (i.e., gas or diesel) are now in effect until at least 4 p.m. Tuesday, August 3, 2021. Ozone concentrations are expected to be in the Unhealthy for Sensitive Groups to Unhealthy range, and concentrations of fine particulates are expected to reach the Unhealthy for Sensitive Groups category on Monday and Tuesday. The highest concentrations of ozone are most likely in the western portions of the Denver Metro area, and elevated levels of both pollutants are possible throughout the Colorado Front Range Region, from Fort Collins and Greeley southward through Colorado Springs.For areas included in this advisory that are not expected to reach the Unhealthy for Sensitive Groups (USG) air quality designation, we request that activities, such as driving non-ZEV vehicles (i.e., gas or diesel), be reduced to lessen the impacts on neighboring air quality. Additional air pollution in this region may directly worsen air quality or contribute to precursors which may also adversely affect air quality.
