T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationIndirect ImpactsIn the event that contaminated soil is encountered, it would likely be removed and groundwater would likelybe treated on-site from six release sites (listed in the Direct Impacts section above), thereby reducing the amountof contamination in the area. USTs would also be removed as described above. Removing the USTs wouldeliminate potential future sources of contamination.Alternative B2 may impact the active remediation systems at the former Fuel Farm (although contamination inthis area may have been reduced to acceptable levels) and the Spring Green Corporation site. The constructionmay also affect the groundwater monitoring wells in place at the Mobil SS #01 site.Significant Impacts: There are no sites in the Project Area, Study Area, or City of Warwick that are listed on theNPL. Therefore there are no significant impacts in the category of Hazardous Materials, Solid Waste, andPollution Prevention as a result of Alternative B2.5.17.4.3 Alternative B4The following direct and indirect impacts may occur during the implementation of Alternative B4. Table 5-128presents a summary of these impacts.Direct ImpactsAs presented in Table 5-128, the proposed limit of disturbance for Alternative B4 could potentially encountercontaminated soil, groundwater, or surface water at four existing nearby release areas: Budget Rent-A-Car,Mobil SS# 01, the former Airport Fuel Farm, and the Truk-Away Landfill. None of these release areas fall withinthe limit of disturbance but may impact soil and/or groundwater within the limit of disturbance. These sites areassociated with the Runway 16 End (three sites) and the Runway 34 End (one site) (Figure 5-49).Based on 30 percent conceptual design plans, 180 residential and commercial parcels consisting of 146 structureswould be fully acquired for Alternative B4, including 39 mandatory acquisitions for construction, 64 voluntaryacquisitions for clearing the Runway 5 End RPZ, and 77 residential parcels are eligible for voluntaryparticipation in an acquisition program for noise mitigation (Table 5-128). Sixteen parcels would be partiallyacquired for construction (mandatory acquisition).Twenty-three of the properties consisting of eight structures that would be acquired for construction arecurrently being used for commercial or industrial purposes. The greatest number of commercial and industrialproperties that would be fully or partially acquired for construction is at the Runway 16 End in the vicinity ofthe Partially Relocated Airport Road. These properties could potentially have soil and groundwatercontamination. Alternative B4 would require demolishing Hangar No. 1, which is known to contain asbestos.Seven registered USTs would be impacted (removed) under Alternative B4 (Table 5-128). Four of the USTs areat the Runway 16 End or near the construction of the new Split Cargo Facility, and three USTs are in the vicinityof the runway protection zone at the Runway 5 End (Figure 5-49). Construction of Alternative B4 would resultin approximately 5.5 acres of asphalt (Table 5-128).Chapter 5 - Environmental Consequences 5-266 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
