DEC seeks public comments on GM’s Lockport brownfield plan

LOCKPORT – The state Department of Environmental Conservation announced it will take public comments until Sept. 14 on General Motors’ proposal to clean up a brownfield around four buildings at the GM Components Holdings plant in Lockport.

The plan calls for keeping the buildings intact while injecting a soluble organic substrate into the ground water to enhance the breakdown of chlorinated volatile organic chemicals on the site, which is south of Building 9 and a parking lot. The contaminants in the ground produced vapor beneath Buildings 7, 7A, 8 and 10. Building 7 is the primary manufacturing facility at the auto parts plant, although the others also are used for that purpose.

The total brownfield area, most of which is covered either by buildings or parking lots, totals 127.6 acres out of the entire 342-acre GM complex. It is in the central and southeastern portions of the GM property and is located entirely within the part of the GM property that lies within the City of Lockport’s borders.
