Welcome to the Illinois Environmental Protection Agency

 *Updates

Due to the Coronavirus pandemic, vehicle emissions testing has been temporarily suspended. All test stations will be closed through April 30, 2020. The closure may be extended depending on circumstances. The Secretary of State’s Office (S0S) has extended vehicle registration expiration dates to at least 30 days after SOS Drivers Services facilities reopen, allowing motorists to wait to have their vehicles tested and renew vehicle registrations. SOS Drivers Services facilities are currently closed through April 30, 2020. The Illinois Air Team Call Center remains open and available to address motorist emission testing questions.

We safeguard environmental quality, consistent with the social and economic needs of the State, so as to protect health, welfare, property and the quality of life.
