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

The Resource rss

Helping communities and businesses access compliance, technical and financial assistance for their environmental needs.

The newly formed OCS connects customers in need of environmental assistance to the people and resources that can make that happen. OCS is the “front door” to the Agency’s services and staff travel across the state to provide Ohio communities and businesses the information they need to connect them with resources they can use.

OCS publishes a quarterly electronic newsletter and easy-to-understand technical publications. DEFA listserv subscribers receive a monthly email update (eBlast) with information on deadlines, training events and new publications. OCS coordinates DEFA’s free webinar training series. Speakers are available to present an overview of DEFA services at meetings and conferences. The office also coordinates special assistance initiatives that bring together technical and funding experts to help address environmental challenges for businesses and communities.

Please email if you are interested in any of these services, or to receive the quarterly electronic newsletter and monthly email updates. You can subscribe to our electronic listserv or other Ohio EPA listservs at:

You can also call (800) 329-7518, our compliance assistance hotline, or (614) 644-2798, our main number, with questions from Monday through Friday 8 a.m. - 5 p.m., or go to our website at: for more information. We look forward to hearing from you!

Do you want to receive the latest news from DEFA as it happens?

This summer we launched our outreach web site in a blog format called The Resource. Our monthly eBlasts and quarterly newsletters post to the blog. We post weekly updates to the blog with the latest training announcements, publications, stakeholder input opportunities, and deadline reminders. You can check our postings on the blog and subscribe via an RSS feed, which notifies you when there is a new posting. Just click on the RSS icon  to subscribe. You can subscribe for the entire blog site, or for a specific category like stakeholder input. You can also search the blog site by category/topic in the search box.

We recently added a training calendar to our website. We post DEFA webinars, other agency training and partner organizations that offer training of interest to our customers. You can view the training for a month, or in a list format. The calendar even prompts you to send yourself an email about a specific training opportunity.

The Office of Outreach and Customer Support is committed to connecting you to the latest information.
