Air Pollution Board Emission Testing Update

Update March 22, 2020: In order to facilitate the treatment and containment of COVID-19, Governor Lee issued Executive Order No. 15 on March 19th extending motor vehicle registrations expiring March and April. The new expiration date is now June 15, 2020. Therefore, the requirements for vehicle emissions testing are suspended until further notice. The Division of Air Pollution Control will update this notice with details as to when vehicle emissions testing services will resume in the near future. The Division of Air Pollution Control will work to ensure testing services are available in enough time for vehicles to be tested prior to the extended registration due dates.

Emission testing remains in effect prior to titling or renewing a vehicle registration until repeal is approved by the United States Environment Protection Agency (EPA).

The Tennessee Department of Environment and Conservation announced in May 2019 that they will recommend elimination of emission testing in counties, including Hamilton. The State Implementation Plan revisions eliminating the vehicle emissions testing program were submitted to the EPA on February 27, 2020. The program will end 120 days after the EPA approves the State Implementation Plan revisions. Updates will be posted as they become available.
