Future Changes in Vehicle Emission Program

Public Chapter 953 was enacted by the 110th General Assembly and signed by Governor Haslam on May 15, 2018. The law seeks to eliminate the vehicle emissions testing program (Inspection and Maintenance Program) implemented by the  Tennessee Department of Environment and Conservation, Division of Air Pollution Control when the state receives EPA approval to do so.  The law did not seek to eliminate the program immediately. Therefore, the program will continue in Hamilton, Rutherford, Sumner, Williamson, and Wilson counties until EPA approves the state’s request to eliminate the program.  The law allowed Metropolitan Nashville/Davidson County to choose whether to continue its program and the
Metropolitan Council voted to keep the testing program.  Information included on this page is intended to provide basic information about the law change and questions the change may generate. The Division will periodically update this page as further information is gained.
