Ada and Canyon County Emissions Testing Programs Terminated on July 1, 2023.
If you previously received a postcard notifying you of the test requirement, you may disregard it, even if the testing due date was prior to July 1, 2023. You are no longer required to test. If you received a letter that your registration had been revoked due to failure to comply with emission testing requirements, your registration was automatically reinstated on July 1, 2023, and no further action is required of you. If you have additional questions, please contact the Air Quality Board at 208-475-2228.
