“Nashville and the surrounding counties stopped emission testing in the last year. EPA approved, the air quality in Nashville has improved.”
Since the emission equipment on the cars on the road hardly changed that can’t be the reason.
“Does this mean vehicle emissions testing is gone for good in Davidson County?
Not necessarily.
According to provisions in state law, if Davidson County becomes noncompliant with Environmental Protection Agency air quality standards, the EPA could mandate the county institute an emissions program again in the future.
But local health department officials say emissions testing controls just 2% of the county’s total emissions of pollutant Nitrogen Oxide.
“Our feeling is that if we do slide into non-attainment, it won’t be because we don’t have vehicle emissions testing,” Metro Health Department Policy Director Tom Sharp said. “We’ll have other things that we’ll need to address.”
But it's been a few years since I've seen or heard about the brown haze hanging over Nashville.
But as the Tennessean article I just posted pointed out. Vehicle emissions is only 2%.
There was a municipal waste to thermal burning plant downtown from 1974 to 2004. I wonder how much pollution that thing put out.
