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 firstname.lastname@epa.ohio.gov 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

Although Ohio’s vehicle anti-tampering law has been in effect for more than 25 years, vehicle owners, autobody shops, dealerships and auction houses are still being affected by tampered vehicles.

Tampering with a vehicle’s emissions control systems creates more air pollution and can result in high repair costs. Tampering can also negatively affect vehicle performance and void warranties.

So what’s illegal? According to Ohio Revised Code Section 3704.16, tampering means "to remove permanently, bypass, defeat, or render inoperative, in whole or in part, any emission control system that is installed on or in a motor vehicle." Tampering includes acts such as: removing the catalytic converter from a vehicle and installing a straight pipe; removing the substrate from inside the catalytic converter (cleaning it out); removing an air pump or disabling the air pump by removing the air pump belt; or installing a nonstandard thermostatic air cleaner.

The law enhances Ohio EPA’s authority to enforce existing tampering-related prohibitions such as selling or installing a device on a vehicle that would damage or bypass any emission control system. The prohibitions in the law apply to vehicles sold as is as well as those sold with warranties.

To help ensure that those affected understand their responsibilities, Ohio EPA’s Division of Air Pollution Control (DAPC) and Office of Compliance Assistance and Pollution Prevention (OCAPP) hosted a webinar on Oct. 2. This webinar defined illegal tampering and gave examples of different tampering scenarios. To view the recorded webinar, go to: youtu.be/K8QzuJarHH8.

Violation could result in fines or felony charges. In 2018, an Ohio auto dealership was fined $40,000 for selling tampered vehicles. To request assistance, file a complaint or get more information visit epa.ohio.gov/dapc or call (614) 644-2270.
