Air Pollution Board Emission Testing Update

Update June 22, 2020: Vehicle Emission Testing remains in effect prior to titling or renewing a vehicle registration until repeal is approved by the United State Environment Protection Agency (EPA). All area testing centers are open with limited contact testing and contactless payment. To view area testing centers hours of operation and Opus Inspection’s updated COVID-19 policies and procedures visit www.tnvip.org . All tag renewals require an emission test. An emission test is also required for ALL first time applications purchased June 1, 2020 and after.

First time applications with a purchase date prior to June 1, 2020 do not require an emission test.

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.
