Project Title: Availability of Voluntary Cleanup Project Remedial Action Work Plan for Comment
Babylon Yard (LIRR) Site No. V00385-1
Project Location: Region 1, Suffolk County, Town of Islip, Hamlet of West Islip, south of Foxglove Rd. and adjacent to the Rail Road Tracks.
Brief Project Description: The Metropolitan Transportation Authority/Long Island Rail Road (LIRR) currently operates the Babylon Yard Substation which is situated in the southwestern portion of the larger Babylon Yard Rail Road facility. The LIRR commenced operation of substations from the early 1930s through 1951 that utilized mercury rectifiers. These rectifiers allowed the LIRR to receive 60-cycle, alternating current (AC) from local utilities and convert it to direct current (DC) for use as a source of electric power for its locomotives and electric passenger car fleet. It is believed that during the early 1980s, the mercury rectifiers were taken out of service and physically removed from the Babylon Yard Substation and replaced with non-mercury containing solid state equipment. Uncertainties surrounding the work practices that may have been employed when managing the operation and maintenance of these mercury rectifiers are suspected to be the cause of contamination.
Environmental Investigations at the site confirmed the impacts of mercury contamination to the surface and subsurface soils at the site. The investigations also confirmed the presence of Polychlorinated biphenyls (PCBs) in soils adjacent to electrical transformers. The majority of the contamination ( mercury and PCBs) is present in shallow soils from the surface to 4 feet below grade. The mercury and PCB contamination is limited to the LIRR property.
Reports describing the investigations are available at the Public Document Repositories listed below.
Proposed Remedial Action: The proposed remedial action for the Babylon Yard Substation includes the excavation and off-site disposal of approximately 61 cubic yards of mercury and PCB contaminated soils. The depth of excavation varies from the current grade (ground surface) to four feet below grade. Removal and off-site disposal of surface and subsurface contaminated soils from the site will mitigate the potential for the direct exposure to contaminated soil. A deed restriction to restrict future uses of the property will be required in the event that any contaminated soils, above soil cleanup guidance levels, remain in place after excavation activities.
The LIRR intends to redevelop the Babylon Yard Substation after excavation activities are completed to increase the yard’s current train storage capacity. Two sets of tracks and associated equipment will be installed over the former electric substation area.
Comment Period: The Remedial Action Work Plan, dated November 2006 and the associated November 29, 2006 and December 13, 2006 letter addenda are available for review at the locations below. Written comments regarding this work plan and the proposed remedy will be accepted for 30 days following the date of this notice. Written comments expressing objection or opposition to the proposed remedial action must explain the basis of that opposition and identify specific grounds which would lead the Department to impose significant changes to the work plan. No formal response will be made to comments received, but, as a result of comments, the Department may reevaluate and make revisions to the work plan.
