80 LISTER AVE

The Diamond Alkali Superfund Site includes the former pesticides manufacturing plant and surrounding properties at 80 and 120 Lister Avenue in Newark, New Jersey, the Lower Passaic River Study Area, the Newark Bay Study Area and the extent of contamination. The Lower Passaic River Study Area includes the 17-mile tidal stretch of the river from Dundee Dam to Newark Bay, and tributaries. The Newark Bay Study Area includes Newark Bay and portions of the Hackensack River, Arthur Kill and Kill Van Kull. Because the problems posed by the upland part of the site are significantly different from those in the Passaic River and Newark Bay, the site was divided into three operable units: the 80 and 120 Lister Avenue properties, the Lower Passaic River Study Area, and the Newark Bay Study Area. The area is both densely populated and heavily industrialized. From 1951 to 1969, the Diamond Alkali Company (subsequently known as the Diamond Shamrock Chemicals Company) owned and operated a pesticides manufacturing plant at 80 Lister Avenue in Newark. The property was used for manufacturing by numerous companies for more than 100 years. The mid-1940s marked the beginning of the manufacturing operations related to the current site conditions, including the production of DDT and phenoxy herbicides. Subsequent owners used the property until 1983, when sampling at the site and in the Passaic River revealed high levels of dioxin. Dioxin (also known as 2,3,7,8-tetrachlorodibenzo-p-dioxin or TCDD) is an extremely toxic chemical and an unwanted byproduct of the manufacture of certain chemicals which were produced at the site. Since Occidental Chemical Corporation (OCC) is a successor to the Diamond Shamrock Chemicals Company, OCC is required to perform remedial activities at the 80 and 120 Lister Avenue properties and the Newark Bay Study Area under the Superfund program. For the Lower Passaic River Study Area, a more innovative approach is being taken. In 2004, EPA formed a partnership with the U.S. Army Corps of Engineers (the Corps), New Jersey Department of Transportation (NJDOT), U.S. Fish and Wildlife Service (USFWS), National Oceanic and Atmospheric Administration (NOAA) and New Jersey Department of Environmental Protection (NJDEP) to conduct a joint study of the Lower Passaic River. The joint study is an integration of a Remedial Investigation/Feasibility Study (RI/FS) under Superfund and a Feasibility Study under the Water Resources Development Act (WRDA). A group of 43 potentially responsible parties (PRPs), including OCC, is required to provide funding for the Superfund portion of the integrated study. In May 2007, a group of 73 PRPs (named the Cooperating Parties Group or CPG), including the above 43, took over the performance of the Superfund portion of the study, under EPA oversight.
