The news comes in the American Lung Association's latest State of the Air 2014 Report, released annually.

The report grades state and local area air quality on an A through F scale by comparing local ozone and small-particulate concentrations with the federal air quality standards.

Although many areas, especially within California, were given failing grades, Lake County passed with flying colors.

Lake County received an “B” grade for ozone, an “A” grade for short term particulate pollution, and is ranked the Cleanest County in the Nation for annual particulate average concentrations for the second consecutive year.
