The Environmental Protection Agency announced that Fort Collins and the Northern Colorado region missed the federal air quality standards deadline.

The Coloradoan reports that the EPA has marked nine counties in the Northern Front Range region with serious noncompliance with the federal standard.

The front range has high ground-level ozone and smog. This might lead to respiratory health issues, as well as heart disease.

The Air Quality Control Commission passed a zero-emission vehicle standard Friday in efforts to reduce effects.
