The owners of the Alabama landfill that is taking about 10,000 tons per day of coal-ash waste from a collapsed Tennessee Valley Authority storage site in Kingston, Tenn., have filed for bankruptcy. Perry Uniontown Ventures I LLC, which owns the Arrowhead Landfill in Perry County, filed papers in federal court in Mobile last month saying facility operators Phillips & Jordan and Phill-Con Services are withholding money they have received from TVA. The operators claim an “outstanding balance” owed them by the owners. A spokesman for the landfill owners says the site will continue to operate, and a TVA official says “we have been assured” by landfill operators the facility will continue to receive ash for the foreseeable future. No backup site has been chosen. As of last month, TVA had shipped 1.3 million tons of waste by train to the landfill, but the operations are opposed by nearby residents.
