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 11, 2020. Ozone concentrations are expected to be in the Moderate to Unhealthy for Sensitive Groups range on Monday and Tuesday. Concentrations of ozone in the Unhealthy for Sensitive Groups category are most likely for locations within the Denver Metro area, including the surrounding suburbs and lower foothills. 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.
