Mercury Reduction

In case of a spill, contact Ohio EPA's spill hotline at 1-800-282-9378.

Mercury is a persistent bioaccumulative toxic metal that is widely used in many products (Introduction to Mercury). Once mercury is released into the environment, its toxicity, persistence and ability to travel up the food chain are important issues for human health and the environment. Ohio has a statewide health advisory for mercury from fish consumption for sensitive populations: women of childbearing age and children 15 years old or younger, issued by Ohio's Department of Health (Ohio Sport Fish Consumption Advisory). The following websites provide information on pollution prevention, alternatives to mercury containing products, locations to drop off old mercury containing products and information on what to do in case of a spill.

Great Lakes Regional Collaboration Mercury Phase-down Strategy

The Great Lakes Regional Collaboration Mercury Phase-down Strategy has been finalized (June 2008). The strategy can be accessed here.

 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
