There's a push in the state legislature to end emissions testing in Rutherford and five other Tennessee counties where it's currently required.
The bill, which is sponsored by two Chattanooga area lawmakers, has been introduced. Senator Bo Watson and Representative Mike Carter believe it's no longer necessary because Tennessee is now in compliance with federal clean air standards.
A report from the Tennessee Department of Environment and Conservation reported in August of last year the entire state is now in compliance with federal air quality health standards for particle pollution.
Opponents of the bill say the state's vehicle emissions testing in metro areas is an important tool to ensure clean air.
