T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) EvaluationAir Sparging (SVE/AS) to remediate petroleum-impacted soil, removal of buried solid waste for proper off-sitedisposal, construction of engineered controls, establishment of institutional controls, and the implementation ofa groundwater and surface water quality monitoring program. A Remedial Action Work Plan was submitted toRIDEM on March 8, 2004. The Spring Green Corporation site is considered Active by RIDEM and requireson-going remediation.The Environmental Land Use Restriction (ELUR) for the site requires annual inspection and maintenance of thesoil cap, prohibits the use of the site’s groundwater as a potable water source, and requires notification ofRIDEM for planned soil excavation activities. The ELUR will restrict future use of the site toindustrial/commercial land uses. A soil management plan was also prepared for this site.Rhode Island State Sites ListThe Rhode Island State Sites List is an inventory of properties for which RIDEM Division of Site Remediationhas reviewed site assessment data. These assessments were submitted voluntarily or as part of state regulatoryactions. The majority of the listed sites does not require further response actions pursuant to the RemediationRegulations, but may affect soil or groundwater conditions within the Project Area.Strawberry Field Estates is located at 333 Strawberry Field Road (Figure 4-34). The Strawberry Field site is listedas an inactive LUST site, but is considered an active State Site by RIDEM requiring further response actions.The Forest Company is located on the north side of Airport Road between Greenacre Avenue and CommerceDrive (Figure 4-34). The contaminants (tricholorethylene) detected in the soil and groundwater at the site aresimilar to those found at the former Mays, Marshall & Meier, Co. west of the Forest Company Site.Groundwater flow from that site is expected to flow to the southeast, in the direction of the Forest Companyproperty.Groundwater at the NE Clarklift site, which is located southeast of the Mays, Marshall & Meier, Co. site andadjacent to the Forest Company, was found to be contaminated with trichloroethylene, 1,1 dichloroethane,1,2 dichloroethylene, and vinyl chloride. RIDEM concluded that NE Clarklift is a down gradient receptor ofcontamination emanating from the Mays, Marshall & Meier Co. site. Similar to Forest Company, groundwaterat the NE Clarklift site flows in a southeasterly direction from Mays, Marshall & Meier Co. A study done byEnvironmental Advisory Group, Inc. and Ferrari Engineering, Inc. concluded that Forest Company is also adown gradient receptor.An ELUR was proposed as the remedial alternative for the site in 1998. The purpose of the ELUR is to assure thecontaminated site is not used for residential activities, groundwater at the portion of the contaminated site is notutilized as potable water, and subsurface structures are not constructed over groundwater at those portions ofthe contaminated site characterized by hazardous substances in groundwater at concentrations exceeding theapplicable RIDEM-approved Groundwater Objectives.Chapter 4 – Affected Environment 4-81 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH04_Affected_Env_JUL_2011.doc
