A nearly year-long cleanup on a 20-acre spot of the former Hanna Furnace site at Buffalo Lakeside Commerce Park is underway, the state Department of Environmental Conservation announced Friday.
The $7.4 million project is expected to include the excavation and disposal of blue-colored fill contaminated with cyanide and numerous other clean-up goals near the city's Union Ship Canal, according to the DEC.
The site was used during the region's industrial heyday as an iron foundry.
In all, about 75,000 cubic yards -- just less than the volume of an Olympic swimming pool -- will be excavated in all, documents show. About 10 percent of that will be taken of site for disposal as hazardous waste, officials said.
DEC reports show that clean fill will be added and a cover will be installed at the site. That will allow the Buffalo Urban Development Corp. to redevelop the property for commercial use, the DEC said.
The project is being completed under the state's Superfund program. Work is expected to be finished next June.
