NEW YORK The U.S. Environmental Protection Agency has released Alcoa Inc.s plans for cleaning up some four decades worth of pollutants from the Grasse River in upstate New York.
Alcoa operates two aluminum smelters in nearby Massena, N.Y., which have a combined nameplate annual capacity of 252,000 tonnes.
Pittsburgh-based Alcoa estimates that EPAs proposal will cost it $85 million in its third-quarter results.
The proposed remedial action plan is now open for public comment until Nov. 15. The EPA will review the comments and issue a final decision. Alcoa will then initiate the planning and design phase, which will take two to three years, the company said.
The field work will take about four years, with the majority of the funding for the project expected to be spent between 2016 and 2020.
"Alcoa has worked cooperatively with the EPA to address the PCB (polychlorinated biphenyl) sediments in the Grasse River, and we are pleased to see this important step in the remediation process move forward," Alcoa vice president and chief sustainability officer Kevin Anton said in a statement.
