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.

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.

RCRA (Resource Conservation and Recovery Act, 1976) — Regulations established under this act set management standards for hazardous and nonhazardous waste.

MSDS (Material Safety Data Sheet) — Part of the Hazard Communication Standards set up by the Occupational Safety and Health Administration (OSHA) to protect workers from chemical hazards. The MSDS for a chemical outlines: composition of the substance, trade name, manufacturer’s name, hazards and precautions for handling the material.

TCLP (Toxicity Characteristic Leaching Procedure) — A laboratory test used to detect the concentration of heavy metals (such as mercury, cadmium, lead, etc.) and/or organics in an extract of waste. Wastes that contain toxic contaminants in concentrations that are greater than regulatory levels are classified as hazardous wastes.

TSDF (Treatment, Storage and Disposal Facilities) — A facility that conducts hazardous waste treatment, storage or disposal activities. Facilities must receive an EPA permit for these activities.
