As a precautionary response to COVID-19, Ohio EPA is currently operating with most staff working remotely. If you are working with our staff on a current project and you know the name of the employee you are working with, email them at or call them directly. The Agency website has contact information for every district, division, and office. In order to reach us, please contact Ohio EPA’s main phone line at (614) 644-3020 or the main line for the division or office you are trying to reach.

After March 23, our district offices and Central Office will be temporarily closed and will have increasingly limited ability to receive deliveries, plans, etc. All entities are encouraged to submit plans, permit applications, etc., electronically where there are existing avenues to do so, such as the eBusiness Center (eBiz). Please refer to the list of available services on the main eBiz webpage. We encourage you to make use of all that apply, even if you have not used eBiz in the past. Plans under 25 MB can be emailed. For large plans over 25 MB, entities should work with the reviewer/division to upload via LiquidFiles. Directions for submitting docs via LiquidFiles is available on YouTube. We apologize for the inconvenience and thank you in advance for your understanding. If you wish to send hard copies of documents to any of Ohio EPA’s district offices, the best method to ensure we receive these documents is to send them via U.S. Mail. Since all offices are closed, deliveries outside of U.S. Mail (FedEx, UPS) will likely be returned because the offices are closed and deliveries cannot be made.

To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946

Emissions Testing in Other States

If a vehicle is registered in an Ohio E-Check county and is permanently, temporarily or indefinitely housed out-of-state, it is not exempt from the Ohio E-Check requirements. If the vehicle is located in a state with a testing program, you must test the vehicle and send the vehicle's original passing test certificate, a readable copy of the vehicle's registration and an Ohio E-Check Exemption/Extension application [PDF] to Ohio EPA.

*Ohio motorists will need a "reciprocal emissions inspection." If the station operator has questions, the station should call (866) 941-6277 for assistance.

**Ohio vehicles will need to be tested at a Private Inspection Center. Make sure the vehicle receives a complete test. Tune-up tests will NOT be accepted. Call the number provided to arrange an appointment.

***Ohio motorists will need to request a "Voluntary Emissions Test" so that the vehicle will not be subject to a complete safety and emissions test.
