MASSENA -- The New York State Department of Environmental Conservation is taking public comments on a Brownfield clean-up application at the Alcoa west plant.
The work, according to the DEC, will remove polychlorinated biphenyls from the former Continuous Mill site, which was decommissioned in 2000. Hydraulic systems in machines used there between 1954 and 1972 used PCBs. Sampling conducted in 2011 showed the mill's floor slab had PCB contamination levels of about 50 parts per million - federal regulations call for premeditation at 10 parts per million.
A news release from DEC says the former furnace area and coiler pit showed "significantly higher concentrations."
The Brownfield applications is available for review at the Massena Public Library, 41 Glenn St. Go to http://www.dec.ny.gov/chemical/60058.html for information about how to submit comments.
