The Youngstown Vindicator reported today that Patriot Water Treatment LLC and the city of Warren will be blocked from treating briny wastes, effective April 1.
The order came from the Ohio Environmental Protection Agency.
The facility is the lone brine-wastewater treatment plant in Ohio. It opened last May.
Patriot Water Treatment removed some heavy metals from the waste. It was then shipped to the city's sewage plant. It was diluted and then discharged to the Mahoning River.
The wastes had high levels of total dissolved solids.
The previous permit expired Jan. 31.
The company and the city have appealed the EPA's closure of the plant that is taking brine wastewater from hydraulic fracturing or fracking in Ohio and Pennsylvania.
