NIAGARA FALLS – The state Department of Environmental Conservation announced Tuesday that a 45-day public comment period will begin today regarding Covanta Niagara’s brownfield cleanup plan for 15 acres of land on which the company intends to construct a new rail station to accept garbage to be hauled in from New York City.

It’s part of a $30 million expansion of the garbage incinerator’s operations, for which it was handed a 15-year property tax break last week by the Niagara County Industrial Development Agency.

The rail transfer station is to be constructed on land off 47th Street that Covanta is buying from Praxair. The DEC says radioactive slag, underground storage tanks and various contaminated sediments are to be removed or paved over.

The site was developed a century ago by the metals division of Union Carbide Corp., and later became its Linde Division. Praxair is Linde’s corporate successor. The location includes a 13,700-square-foot abandoned building once used to service locomotives.

Information on the projects and how to submit written comments is available on the DEC website.
