The Site is currently only partially fenced, undeveloped, and contains limited vegetation <br />established by secondary succession. A Site plan depicting the former Site features is shown <br />on Figure 2. <br />1.2 Site History <br />The Site served as a rail yard from the time when it was first developed until some time in the <br />1980s. A small railroad yard house, tool sheds, gate, scale, and rail spurs were in use at the <br />Site during its operational history, but all have since been removed. The Site is currently <br />vacant. <br />1.3 Previous Environmental Investiaations <br />In January 2007, Hull completed a Phase I ESA concurrently for the Site and an adjacent parcel <br />for the City in preparation for potential purchase by the City. Although no specific Recognized <br />Environmental Conditions were identified in connection with the Site, given the known impacts <br />to groundwater downgradient of the Site, given the nature of historical operations at the Site, <br />and given the fact that persons familiar with operations at the Site prior to 1963 were not <br />available for interviews, the Phase I concluded that the potential existed that historical <br />operations at the Site may have impacted soil and /or groundwater at the Site. Potential <br />chemicals of concern (COCs) identified in the Phase I ESA included volatile organic compounds <br />(VOCs), semi - volatile organic compounds (SVOCs), and metals. <br />Accordingly, the City retained Hull to complete a Phase II ESA. In January 2007, Hull installed <br />borings and collected soil and groundwater samples at the locations shown on Figure 2. <br />Sampling locations where concentrations of COCs in soil exceed RISC IDCLs are shown on <br />Figure 2. <br />1.4 Current Environmental Concerns <br />Based on the information provided in these investigations, it can be concluded that soil <br />contamination is present at the Site in concentrations that exceed Indiana RISC <br />Commercial /Industrial pathway- specific Closure Levels. Specifically, arsenic is present in soils <br />at the Site at a concentration exceeding the direct contact exposure pathway. Lead is present <br />in soils at the Site at a concentration exceeding the direct contact and construction worker <br />exposure pathways. Because the City has not yet determined if the Site will be added to the <br />adjacent Studebaker Automotive brownfield redevelopment (which is enrolled in the Indiana <br />HULL & ASSOCIATES, INC.
