The U.S. Environmental Protection Agency has announced the start of construction needed to remove contaminated sediment from the lower Passaic River. This is an important milestone in the cleanup of this heavily contaminated stretch of the Passaic adjacent to the Diamond Alkali Superfund site in Newark, New Jersey. The sediment in this area of the river is highly contaminated with dioxin, which can cause serious health effects, including cancer. Vertical steel walls will be installed in the river to enclose the area, making it possible for EPA to remove the sediment without spreading contamination during dredging. EPA Regional Administrator Judith A. Enck was joined by Senator Robert Menendez, Congressmember Bill Pascrell, Jr., U.S. Army Corps of Engineers Colonel John Boule and New Jersey Department of Environmental Protection Commissioner Bob Martin to mark the start of the cleanup.
“ The cleanup of this section of the Passaic River will remove the most highly contaminated sediment, which is a continuing source of contamination flowing downstream ,” said Judith A. Enck, EPA Regional Administrator. “ This is a critical step toward the ultimate goal of cleaning up this river and making it an asset to the communities along its banks.”
“ The cleanup of the lower Passaic River, one of the most severely contaminated waterways in the world, is a top environmental priority of the Christie Administration, ” said New Jersey DEP Commissioner Bob Martin . “ New Jersey has been steadfast in its position that those companies responsible for this egregious, intentional pollution be held accountable for the cost of cleaning it up. Today marks an important step toward our ultimate goal — a fully restored and healthy Passaic River that can once again be a swimmable and fishable natural resource to benefit Newark and New Jersey’s other overburdened urban communities. ’’
“ The U.S. Army Corps of Engineers applauds the EPA for advancing this first phase of the cleanup of the Lower Passaic River ,” said Col. John R. Boule’ II , the Army Corps’ New York District Commander. “ 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. ”
Under a June 2008 agreement between EPA and Occidental Chemical Corporation and Tierra Solutions, Inc., the companies will remove 200,000 cubic yards of contaminated sediment from the badly contaminated area directly in front of the Diamond Alkali site. The EPA and the U.S. Army Corps of Engineers will oversee the work.
The cleanup of the lower Passaic River has been divided into two phases. The first phase of cleanup announced today is designed to protect the river, workers conducting the cleanup and the communities along the river. In this first phase, about 40,000 cubic yards of the most highly contaminated sediment will be removed and then piped to a processing facility beginning in the spring of 2012. That facility is currently under construction a quarter mile downstream from the Diamond Alkali site at 117 Blanchard Street. There, the water will be squeezed from the contaminated sediment, treated and then transported by rail to a licensed disposal facility. Air and water monitoring at the work locations will ensure safe operations.
In the planned second phase of the project, 160,000 cubic yards of sediment, much of it with lower levels of contamination than the first 40,000 cubic yards, will be removed from the same area of the Passaic River. The two-phase removal project is just one installment in a more comprehensive investigation of the contamination and evaluation of cleanup options for the lower eight miles of the Passaic River and possibly other stretches of the river and Newark Bay.
