T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluation4.16.2.1 Hazardous MaterialsA review of federal and state environmental databases, and state records was conducted to identify propertieswithin the Project Area and the Study Area that have had a release or threat of release of OHM, and may havethe potential to impact the Improvement Program. The majority of sites identified in the database search are notanticipated to present a threat to soil or groundwater within the Project Area based on the distance from theAirport, direction with respect to inferred groundwater flow direction, and/or completed remedial status. Asearch of the NPL revealed that there are no listed sites in the Project Area, Study Area, or the City of Warwick.Further review of sites within the Project Area or upgradient from the Project Area was undertaken to identifythe potential contaminants that could be encountered during construction of the proposed AirportImprovement Program. Figure 4-34 shows the locations of sites identified as a potential source of soil andgroundwater contamination.Storage and Handling of Oil Products at T.F. Green AirportFigure 4-35 shows the numerous oil management areas at T.F. Green Airport. Oil management areas include areaswhere oil products are stored or handled, such as underground and aboveground storage tanks, drums,miscellaneous oil product containers, and fueling areas. The following paragraphs provide an overview of knownaboveground and underground storage tanks on-Airport.Aboveground Storage Tanks (ASTs)RIAC and its tenants maintain 23 ASTs holding more than 300,000 gallons of petroleum products 253 (diesel fuel,gasoline, motor oil, hydraulic oil, waste oil, Jet A, aviation gas, heating oil, and truck oil) all of which are locatedinside the Airport perimeter fencing. Table 4-37 lists the on-Airport ASTs.Underground Storage Tanks (USTs)RIAC and Airport tenants maintain 20 UST systems at T.F. Green Airport, which are listed in Table 4-38.Figure 4-35 shows the location of the on-Airport USTs.According to the Spill Prevention Containment and Control Plan (Revision 3.0 dated April 2004), all USTs at theAirport have been removed or upgraded to meet EPA requirements. 254 According to a letter of complianceissued to RIAC from the RIDEM, RIAC was in compliance with Rhode Island Rules and Regulations forUnderground Storage Facilities Used for Petroleum Products and Hazardous materials at this time.A summary of Emergency Response Activities 255 in 2001 reported that subsurface soil and groundwatercontamination was discovered during excavation activities performed at the Former T.F. Green Fuel Farm withregard to the installation of an oil/water separator (Figure 4-34). Reports from January 2004 to 2010 indicate thatthe potential contaminants of primary concern (benzene, toluene, ethyl benzene, and xylene) are belowdetection limits and that other VOCs associated with the petroleum products were below actionablelevels. RIAC continues to operate the oil/water separator.253 Spill Prevention, Control, and Countermeasure Plan T.F. Green Airport, Fuss & O’Neill, Inc.
