Ohio EPA Considering Permit Variance for Liberty Center Wastewater Plant

A request to grant a variance from the mercury limits allowed in the Liberty Center wastewater treatment plant discharge permit will be the topic of an Aug. 28, 2018, Ohio EPA public meeting. An information session will begin at 6 p.m., immediately followed by a public hearing at the Liberty Center Municipal Building, 110 East St.

If approved, the variance would allow the facility to continue to discharge mercury at current levels which average less than 5 parts per trillion (ppt). The facility would be required to identify the sources of mercury in the discharge and take steps to eliminate or minimize those sources. It would not allow an increase in mercury discharged from the facility.

The water quality standard for mercury discharges in the Lake Erie Basin is 1.3 ppt monthly average. The village’s treatment plant is located at 231 S. Damascus St. and discharges to the Maumee River.

Comments on the proposed permit modification may be presented at the hearing or submitted in writing to Ohio EPA Division of Surface Water, Permits Processing Unit, P.O. Box 1049, Columbus, Ohio 43216-1049, or by email to epa.dswcomments@epa.ohio.gov. The public comment period ends Sept. 4. Please include the entity name or the permit number (2PB00039) with the comments. Following consideration of public comments, Ohio EPA will decide to whether to approve or deny the variance.


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.
