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

Learn the Lingo

Do environmental terms sometimes sound like a foreign language to you? If so, you’re not alone. Many businesses and communities have difficulty keeping up with the latest environmental lingo. This feature will cover some common environmental terms you may encounter.  This time, we’ll focus on some frequently used air pollution control terminology.

Permit-to-Install and Operate (PTIO) — The type of air permit most small businesses need is the PTIO. The PTIO is required before installing and operating an air contaminant source. The PTIO lasts 5 to 10 years and is renewable.

General Permit — A general permit is an optional, “template” PTIO available to certain common air contaminant sources. Because they are developed in advance, general permits eliminate much of the review steps and speed up the permitting process.

Permit-by- Rule (PBR) — A PBR is a specific permit provision in the Ohio Administrative Code that applies to certain types of low-emitting air pollution sources. Companies may use the PBR as an option in place of the PTIO. The PBR is free, does not expire, and requires a simple, one-page notification to Ohio EPA.

De Minimis Air Pollution Source — De minimis sources emit less than ten pounds per day of any air contaminant and less than one ton per year (2,000 pounds) of any hazardous air pollutant or combination of hazardous air pollutants.  If you claim a de minimis exemption based on actual emissions, you must keep records onsite to document actual daily emissions from the source. You do not need to notify Ohio EPA if you claim a de minimis exemption.
