And the mountains of East Tennessee are getting back to being more smoky and less smoggy thanks to the Tennessee Valley Authority. The TVA says its spent $5.3 billion dollars since the 1970s curtailing air pollution from its 11 coal plants. Two of the biggest ozone-producing culprits -- sulfur dioxide and nitrogen oxide -- have reportedly been reduced by more than 90 percent. Those levels are expected to continue declining as TVA closes more coal plants and spends another $2 billion dollars on emission control.
