It’s also good for our tourism economy dependent upon clear skies and viewsheds.

The issue is tremendously complicated. Ozone in the stratosphere provides a shield from ultraviolet radiation. That beneficial ozone layer has been partially destroyed by manmade chemicals, although the hole in the ozone layer is shrinking.

At ground level, ozone is a harmful pollutant that can trigger a variety of health problems, especially for children, the elderly, and people of all ages who have asthma or other lung diseases. Ground-level ozone occurs when pollutants emitted by cars, industrial plants and other sources — in this region, particularly coal-fired power plants — chemically react in the presence of sunlight. The result is smog.

But, in another layer of complexity, ozone targets are more difficult to meet for high-elevations cities, including Colorado’s Front Range, and in desert states like Arizona with a high level of naturally occurring ozone. Wind can move ozone over long distances.
