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

DSW Guidance Documents

The Division of Surface Water maintains guidance documents to provide standard operating guidelines for use by Division of Surface Water employees as they carry out job duties related to water quality and permitting. These staff carry out a variety of tasks ranging from environmental sampling, modeling, facility inspections, plan review and permit writing, all of which have certain requirements stipulated in statute or regulations. Guidance documents provide background and instructions to staff relative to key aspects of their work. This internal guidance does not affect the requirements found in the referenced rules and statutes.

If you would like a copy of any of the guidance documents that are not available in PDF format, call the Division of Surface Water at 614-644-2001 or write to:
