An affiliate of Aqua Ohio, a water delivery and wastewater company, passed Monday’s deadline to purchase the old Youngstown & Southern Railroad.
The Columbiana County Port Authority and the Aqua Ohio affiliate negotiated for months over the 36-mile rail lines, but the company passed.
Port authority executives said Tuesday they are working through the problems.
In August 2012, a proposed $3 million agreement between the port authority and Tervita, a Canadian firm, fell through.
At the time, Tervita executives said they were concerned about an oil spill near the railroad property in Negley that happened in the 1990s.
