摘要

The US Environmental Protection Agency (EPA) recently announced the selection of a final cleanup plan for the first stage of a two-phased project to remove dioxin-laden sediment from the lower Passaic River. The cleanup plan, outlined in an Action Memorandum signed by EPA on January 9, 2009, involves mechanical dredging of 40,000 yd3 of sediment with mechanical processing to dewater the sediment on land nearby.rnThe plan implements a June 2008 agreement between EPA, Occidental Chemical Corporation and Tierra Solutions, Inc. (Tierra) under which the companies agreed to remove, in two phases, a total of 200,000 yd3 of contaminated sediment from the portion of the river directly in front of the Diamond Alkali Superfund site in downtown Newark.rnThat agreement calls for 40,000 yd~3 of the most contaminated sediments to be removed, treated and disposed of at one of a handful of facilities permitted nationwide to accept such waste. The agreement also requires the companies to remove an additional 160,000 yd~3 of sediment with lower concentrations of dioxin and place them in a confined disposal facility.
