ALBANY, NY – The U.S. Environmental Safety Company (EPA) has reached an settlement to dismantle the Powerhouse and Allen Mill in Hudson Falls, NY, with Normal Electrical Firm (GE) and the amenities’ proprietor Niagara Mohawk Energy Company (NMPC), which is owned by Nationwide Grid. The buildings are being taken down due to their deteriorated situation and shall be rigorously dismantled in accordance with situations spelled out in an settlement with the businesses to keep away from a launch of polychlorinated biphenyls (PCBs) and different hazardous substances into the Hudson River. Underneath the phrases of the authorized settlement, GE and NMPC pays EPA’s oversight prices.
The settlement requires NMPC and GE to submit detailed plans to EPA outlining how the constructions shall be taken down with out releasing hazardous substances into the river. The plans embody air, floor water and groundwater monitoring. A Group Air Monitoring Plan will embody an outline of the monitoring method and sampling strategies on the website. That info shall be used to find out acceptable measures to restrict air impacts to the encircling group from website contaminants and mud throughout the work. The businesses are additionally reimbursing EPA for the prices incurred for planning the work.
“This settlement minimizes any launch of hazardous supplies equivalent to PCBs into the river as these buildings are taken aside rigorously and safely,” mentioned EPA Regional Administrator Lisa F. Garcia. “It is usually necessary to protect in opposition to introducing contamination from areas subsequent to and beneath the buildings into the river because the buildings come down.”
The Allen Mill is a former textile mill that was constructed within the mid-1800s and borders the previous GE Hudson Falls facility. The Powerhouse, which is straight away downstream from the Allen Mill, was constructed in 1907 and provided hydroelectric energy to the Mill by way of a system of raceways and tunnels that have been excavated into the bedrock.
Throughout a 30-year interval ending in 1977, PCBs have been discharged into the Hudson River from GE’s two capacitor manufacturing crops positioned in Fort Edward and Hudson Falls. PCB releases from the crops induced vital floor and below-ground contamination. The previous GE Fort Edward and Hudson Falls plant websites are being addressed below New York State’s Superfund program. Underneath New York State Division of Environmental Conservation (DEC) oversight, a tunnel drain assortment system was put in on the Hudson Falls website in 2007-2009, to cease the migration of website PCBs to the river. GE carried out dredging within the higher Hudson River to take away PCB-contaminated sediment, below EPA oversight, between 2009-2015. As well as, DEC directed GE to undertake an intensive soil remedial program on the Hudson Falls website, which eliminated contaminated soil right down to bedrock. PCB contamination stays within the bedrock and is being managed by the tunnel drain assortment system and the groundwater extraction and remedy system working on the GE Hudson Falls facility.
DEC Commissioner Basil Seggos mentioned, “New York State DEC continues to supervise the Hudson Falls website cleanup to make sure the ultimate treatment is protecting of public well being and the surroundings. In partnership and coordination with EPA, the demolition challenge is advancing safely to forestall PCBs from migrating into the river.”
The Powerhouse deconstruction work is scheduled to start in early August. The work will start with the Powerhouse and proceed with the Allen Mill sooner or later. If the Powerhouse work can’t be accomplished this season, it will likely be suspended throughout the winter months and can start once more in spring 2023.
