NEWARK, N.J. -- On Monday, Oct. 31, 2011 the Army Corps, U.S. Environmental Protection Agency, along with elected officials made an announcement at the secured hazardous waste site at the Diamond Alkali Superfund site about work to remove contaminated sediment from the lower Passaic River, in Newark, N.J.
The U.S. Army Corps of Engineers New York District and U.S. Environmental Protection Agency Region II are overseeing the work being performed at two sites.
Construction crews began work earlier this summer and over the past two months workers have prepared and secured the site floodwall along the Passaic. Work began on construction of a metal sheet pile enclosure in the river. Dredging is scheduled to commence next spring, with all work to be completed by the end of 2012. Contaminated sediment will be dewatered and loaded onto sealed containers for transport off-site for disposal.
Approximately 40,000 cubic yards of contaminated sediment will be removed beginning in the Spring of 2012 from within a sheet pile enclosure adjacent to the Diamond Alkali site, then piped to a processing facility that will be constructed one quarter mile downstream.
"The U.S. Army Corps of Engineers applauds the EPA for advancing this first phase of the cleanup of the Lower Passaic River." said New York District Commander Col. John R. Boulé. “However, this is just the initial step on the long journey towards a comprehensive restoration of the river. The Corps looks forward to partnering with the interagency team to make significant additional progress in the near future.”
The project was specially designed to protect the river, workers, and the community. Use of a metal sheet pile enclosure will isolate the contaminated materials from the river. Monitoring at both work locations is being performed to ensure safe operations. During construction, lengths of steel sheet piling will be joined together with the existing flood wall to surround and isolate the Phase I Work Area.
A pump and water level control gate will control water levels in the enclosure as river levels rise and fall during tides and storm events. Warning signs and navigation aids will be installed to alert mariners and boaters to steer clear of the work area. A floating, double-walled hydraulic pipeline will be placed near the southern shore of the river to deliver sediment materials directly to the nearby Upland Processing Facility. The Upland Processing Facility will be built on property approximately 1,400 feet downstream (east) of the sheet pile enclosure. The facility will remove and treat water from excavated sediment materials, as well as stormwater collected from the active work area.
