This Record of Decision (ROD) presents the selected remedial action plan for the Lehigh Valley Railroad Derailment inactive hazardous waste disposal site which was chosen in accordance with the New York State Environmental Conservation Law (ECL). The remedial program selected is not inconsistent with the National Oil and Hazardous Substances Pollution Contingency Plan of March 8, 1990 (40 CFR 300). This decision is based upon the Administrative Record of the New York State Department of Environmental Conservation (NYSDEC) for the Lehigh Valley Railroad Derailment site and upon public input to the Proposed Remedial Action Plan (PRAP) presented by the NYSDEC. A bibliography of the documents include as part of the Administrative Record is included. Actual or threatened release of hazardous waste constituents for this site, if not addressed by implementing the response action selected in this ROD, presents a current or potential threat to human health and environment. Based upon the results of the Remedial Investigation/Feasibility Study (RI/FS) for the Lehigh Valley Railroad Derailment site, approximately three acres of the site at and around the site of the derailment have been designated as a Corrective Action Management Unit (CAMU) for the purpose of remediating the site. The first one and one-half acres contains soils contaminated with trichloroethene which will be treated in ex-situ soil vapor extraction units to be located in the vicinity of the spill site. The treatment area will be the second one and one-half acres (exact size dependent upon design) of the CAMU. Once treated, the soils will be placed back into their original location. Description of the selected remedies are given.
