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 epa.dswcomments@epa.ohio.gov.


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.
