Western Electric, a company owned by AT&T since 1882, was merged into AT&T Technologies, Inc. in 1984. AT&T has assumed responsibility for the remediation of this facility. Relevant supporting materials, including Sanborn Maps, affidavit of a knowledgeable person, and documents obtained from various sources including the NJDEP, are included as Exhibits to this Summary of Evidence and are referenced as appropriate in the text. The sediment sampling data was produced to EPA in January 1994 and April 1996. This Summary of Evidence reflects only the information collected to date, and therefore is not a complete or final analysis of the facts relevant to Western Electric's (and/or its successors-in- interest) liability for costs associated with the Passaic River. The text of this document is organized so as to provide only the relevant evidence indicating Western Electric to be a Potentially Responsible Party for the Passaic River Study Area. Section 2.0 provides an Executive Summary chart identifying the evidence presented within the text, as well as a summary of conclusions which have been reached based upon this evidence. Sections 3.0 and 4.0 summarize the operating History and Discharge History of the former Western Electric facility. Section 5.0 identifies environmental contaminants detected in Passaic River Study Area sediments adjacent to the former Western Electric facility. Section 6.0 presents a summary of these findings. 853890005 2.0 SUMMARY OF CONCLUSIONS The evidence presented in this document, which is summarized in the accompanying Executive Summary chart, supports the following conclusions: | • Numerous hazardous substances have been stored, used and/or produced at the former Western Electric facility during Western EJectric's tenancy. • There are several known and documented discharge pathways to the Passaic River Study Area from the former Western Electric facility. • The historic discharge of hazardous substances from the former Western Electric facility to the Passaic River Study Area has been documented. • Hazardous substances like and including those known to have been used at the former Western Electric facility are present in Passaic River Study Area sediments. Based on these conclusions, Western Electric and its' relevant successors-in-interest should be named as Potentially Responsible Parties for the Passaic River Study Area. 853890006 EXECUTIVE SUMMARY - WESTERN ELECTRIC COMPANY (AT&T) (Al of May 30. 19%) DOCUMENTED DISCHARGES OTHER PATHWAYS TO HAZARDOUS SUBSTANCES LOCATION AND HAZARDOUS SUBSTANCES OF HAZARDOUS SUBSTANCES DISCHARGE USED AT FACILITY FINANCIAL COMPANY YEARS TYPE OF OPERATION STORED/USED/PRODUCED AT TO FACILITY/RIVER HAZARDOUS •DENTIFIED IN PASS ATC VIABILITY OF OPERATION FACILITY SUBSTANCES RIVER SEDIMENTS ADJACENT TO SITE Weoera Electric (AT&T) Wenern Eleclric a) Hiatorkslly Ihe WE ammonia DnchareeitoRmy • Potential procesa wane copper ATAThu 100 Central Avenue located within me facility manufactured and boric acid water and/or spills cyanide reported asaeU Kearny, NJ southern puitiuu of • Prior to conatraclion of Ac discharged lo floor drains lead of over $87 the Pamk River product! that were utilized chlorofluorocarbon facility waate water treatment plant located in manufacturing (ncfcucy billion as of Current Owner/Ooerator: Study Ana on Ihe in the tdecommunkalion! chromium Irioxide in 1973 process waate water and auembly building! dial nickd 1995.
