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. To report a spill or environmental emergency, contact the spill hotline (800) 282-9378 or (614) 224-0946. This number should only be used for emergencies. For all other calls, 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.


Ohio EPA Meeting Set for Greene County Biodigester Expansion

Information Session and Hearing Scheduled March 22, 2018

Ohio EPA will hold a public meeting to discuss an application for a permit allowing Dovetail Energy LLC to expand its biosolids treatment facility in Greene County and improve the quality of its product.

An information session will begin at 6 p.m. on Thursday, March 22, at the Howard Conference Center, Greene County Career Center, 2960 W. Enon Road, Xenia. The hearing will follow to provide an opportunity for public comments on the permit application.

The company is proposing to add two new plug flow tanks that are 2,000 gallons each, a new 230,000-gallon pre-digester tank and a second 1.74 million-gallon digester tank at its 1146 Herr Road, Fairborn facility.

The facility treats biosolids from municipal wastewater treatment plants, hog manure and other approved feedstocks. The current system consists of a liquid and solids unloading area, mixing, pre-digester and digester tanks and a biosolids storage tank. Electricity is produced by the digesting process. The solids produced during treatment are land applied as fertilizer for local farm fields.

As part of the expansion plan, the company also is proposing to upgrade its process to produce exceptional quality (EQ) biosolids which have less stringent land application restrictions.

Ohio EPA will accept written comments on the permit application through March 23, 2018. Anyone may submit comments or request to be on the mailing list for information. To comment or receive information on the permit application, write to: Ohio EPA-DSW, Permits Processing Unit, P.O. Box 1049, Columbus, Ohio 43216-1049 or email


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
