Survey limited to the parcel identified at 529 East Colfax, utilized an approximate 4-foot grid in both north-south and east-west directions. Notes that the western and northwestern portions of the property were snow-covered and that snow interferes with the radar signal; therefore survey not performed on these areas of the site. The report noted that the southern side of property was covered with plowed snow and was therefore considered inaccessible. Site conditions for accessible areas were identified as a muddy gravel surface with staining water present in isolated areas of the property. SER90 stipulated that "saturated conditions at the surface partially inhibited the radar signal, which reduced the clarity of the data generated. However, SER90 stated that the quantity of shallow and near-surface anomalies may be masking the identification of "deeper" anomalies (3-feet or greater). Analysis of the data revealed the presence of large metallic anomalies on the eastern side of the property that would be consistent with the presence of USTs lying end to end, as well as the presence of an excavated area surrounding the tanks. The presence of tanks was evident on the north-south scans; however the east-west profile indicated several shallow anomalies that appeared to be masking the presence of the tank system. Phase II Environmental Site Assessment - dated June 18, 2008, as completed for the Indiana Finance Authority, c% Indiana Brown fields Program, as prepared by Hull & Associates, Inc. Planned scope of services for the project included: 1) Completion of a surface geophysical survey using GPR in an effort to locate orphaned Underground Storage tanks (USTs) beneath the site in areas of historical petroleum station operations; 2) Installation of up to seven direct-push soil borings and analysis of soil samples to identify the potential presence of chemicals of concern in areas that may have been impacted by historical operations at the site; 3) Collection of groundwater samples to evaluate the potential presence of COCs in groundwater underlying the site; and 4) Preparation of a Phase II Report Subsurface anomalies consistent with USTs were detected on the eastern portion of the site by the GPR performed by SER90. During the installation of borings SB-3 and SB-4 in the vicinity of the suspected USTs, no abnormal resistance was noted while drilling, and no evidence of a UST was noted during the logging of soils from the boring. Borings installed in pre-selected locations consistent with anomalies identified from GPR Survey and Potential former UST/Dispenser Island Location based on Phase I Site Assessment. No soil or groundwater samples collected during the investigation exhibited concentrations of COCs exceeding Indiana RISC IDCLs, nor were laboratory detection limits exceeded at any sampling location. Therefore, based upon the results of the Phase II Site Investigation, Hull Associates determined that historical operations at the site did not appear to have impacted soil or groundwater underlying the site. No Further Action Determination Pursuant to Risk Integrated System of Closure (RISC) - dated July 28,2008, as issued by the Indiana Department of Environmental Management Brownfields Staff, as presented to the City of South Bend, Department of Community and Economic Development The document summarizes the background information regarding historical operations conducted at the subject site, and references the Phase I/II Environmental Site Assessments conducted by Hull and Associates.
