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

Ohio EPA offers the Permit Wizard as a tool to assist small- to medium-sized businesses determine their permit requirements.  Also see pages 29-35 of the Ohio EPA Guide to Environmental Permitting in Ohio.


National Pollutant Discharge Elimination System

The National Pollutant Discharge Elimination System (NPDES) requires a permit for all facilities discharging pollutants from a point source to a water of the state. Pollutants are broadly defined as any type of industrial, municipal or agricultural wastewater. Examples of point sources are publicly owned treatment works, industrial facilities and urban runoff. See Ohio NPDES Permit Naming Protocol for permit naming convention. Ohio EPA administers the following NPDES programs:

  • Individual - An individual NPDES permit is unique to a specific facility.
  • General - A general NPDES permit covers facilities with similar operations and wastewater. A general permit is a potential alternative to an individual permit for facilities meeting certain eligibility criteria.
  • Pretreatment - The pretreatment program regulates industrial facilities discharging wastewater to publicly owned treatment works.
  • Storm Water - Storm water discharge is generated by runoff from impervious areas such as paved streets, parking lots and building rooftops. Some storm water discharges are considered point sources and require coverage by an NPDES permit.
  • Biosolids - Biosolids are the nutrient-rich organic materials resulting from the treatment of sewage. Proper disposal of biosolids may require a permit.
  • Concentrated Animal Feeding Operation - Livestock operations meeting certain criteria may require an NPDES permit.

Permit to Install Program

A Permit-to-Install (PTI) is needed for any installation or modification of a wastewater treatment, conveyance or disposal system. Sanitary sewer extension, wastewater treatment plant construction, onsite sewage treatment systems installation, and sewage holding tank installation are examples of projects that may require a PTI.  

401 Certification & Isolated Wetland Program

The 401 Certification and Isolated Wetland Program evaluates projects that physically impact a stream, lake or wetland. Examples of physical impact include the dredging, filling or relocation of a water resource.
