Work is expected to begin in a few weeks to prevent further migration of hazardous materials from the Niagara Transformer Corp. plant at 1747 Dale Road in Cheektowaga.
High levels of cancer-causing polychlorinated biphenyls were found April 10 in a drainage ditch behind the plant.
Niagara Transformer has submitted plans for interim work and long-term investigation for the entire site and its impact on the surrounding environment, Martin L. Doster, the state Department of Environmental Conservation's regional engineer for hazardous waste, said Monday.
The interim plan, prepared by Woodward-Clyde Consultants, calls for intercepting ground water on the site, before it enters the ditch, and disposing of it properly, Doster said.
This will include storm-water runoff as well as underground water, and one or more monitoring wells will be dug to take samples, he added.
The process, still being worked out, may include installing pipes, Doster said.
Revisions have been asked in the plan, but Doster said he hopes work can begin within a month.
The long-term plan, to include investigation of the hazardous materials on and near Niagara Transformer property and means of eliminating any hazards, must be reviewed by the DEC here and in Albany, as well as the state Health Department, Doster said.
He expects the review to take several months.
PCB readings in a 400-foot-long stretch of the ditch, where town Highway Department employees had been working, averaged 2,500 parts per million.
Niagara Transformer has put up siphon dams and fencing along the ditch.
Much lower levels of PCBs -- 11 to 12 parts per million, which are not considered a danger -- were found in a drainage ditch near Grunner Road into which the ditch behind Dale Road flows.
