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

Which Vehicles Must Be Tested

Testing cycle

All gasoline- and diesel-fueled vehicles, including flexible fuel and hybrid vehicles, equal to or less than 10,000 pounds gross vehicle weight rating (GVWR), 25 years old or newer from the current testing year, and registered in an E-Check county must comply with E-Check. All even-model year vehicles must be tested during the even-numbered years (e.g. a 2008 vehicle must be tested in 2014, 2016, etc.). All odd-model year vehicles must be tested during the odd-numbered years (e.g. a 2007 vehicle must be tested in 2013, 2015, etc.).

Please refer to the exempt vehicles section below for a list of vehicles that are exempt from the E-Check program.

IMPORTANT: An inspection certificate is valid for 365 days following the date of the test. You may use that same test certificate to renew your registration if your renewal date falls within 365 days from the initial test.

New vehicles

New vehicles are exempt for the first four model years. For example, 2013 to 2016 model year vehicles are exempt from testing in 2016.

Vehicles permanently exempt from the E-Check program

Some vehicles are permanently exempt from the E-Check test requirement. The following is a partial listing of permanently exempt vehicles:

Please visit the exemption/extension website for additional information.

What is the difference between a 'permanent exemption' and owning a vehicle that is permanently exempt?

Vehicles that are eligible for a permanent exemption must make arrangements for the vehicle to have a one-time visual inspection performed by An appointment that can be scheduled at the Twinsburg field Office or at one of the 23 full service test stations by calling 330-963-4479. These vehicles include:

  1. Electrically powered vehicles (onetime verification inspection by Ohio EPA Mobile Sources Section required.)
  2. Vehicles operating on alternative fuel, such as propane, butane, alcohol, or natural gas (one-time verification inspection by Ohio EPA Mobile Sources Section required.)
  3. Non-commercial vehicles weighing more than 10,000 pounds GVWR 

Several types of vehicles are permanently exempt from the E-Check test requirement and do not need a visual inspection. A complete list with a detailed explanation may be found in Ohio Administrative Code, Section 3745-26-12(c). It is not necessary for vehicle owners that are permanently exempt to be issued an exemption certificate. The most common types are listed below.

  1. Vehicles more than 25 years old, as determined by vehicle model year
  2. Commercial vehicles weighing more than 10,000 pounds GVWR
  3. Historical and collector's vehicles (contact Ohio BMV for details)
  4. Parade and exhibition vehicles (contact Ohio BMV for details)
  5. Motorcycles, recreational vehicles and motor homes (contact Ohio BMV for details)

There may be other circumstances under which you may qualify for an exemption or an extension. If you have questions, contact an Ohio EPA E-Check field office or the Ohio EPA Mobile Sources Section, P.O. Box 1049, Columbus, OH 43216-1049. Phone: (614) 644-3059.

Title transfers

Whenever a vehicle's title transfers to another individual within one of the seven E-Check counties and that vehicle's emissions test has expired, that vehicle must be tested. Vehicles within the four year exemption period do not test on a title transfer. Vehicles that are 25 years old or newer and were titled out-of-state must also be tested before they are registered in Ohio. If the previous owner has a valid test certificate, the new owner may use it to register the vehicle. In the event the previous owner does not have the certificate or is not sure if the vehicle has been tested in the last 365 days, please call 1-800-CAR-TEST to obtain this information. Please have the Vehicle Identification Number (VIN) available.

IMPORTANT: An inspection certificate is valid for 365 days following the date of the test. If a vehicle that has undergone a title change is registered within 365 days from a previous test, then the new owner will not need to have the vehicle tested again in order to register. An inspection certificate is valid for one full year from test date, regardless of title changes.
