T.F. Green Airport Improvement ProgramEnvironmental Impact Statement and Final Section 4(f) Evaluationrelease sites, thereby reducing the amount of contamination in the area. USTs would also be removed whichwould eliminate potential future sources of contamination.5.17.8 Avoidance and MinimizationAlternatives B2 and B4 would not result in significant impacts as defined in FAA Order 1050.1E. They would bedesigned and constructed in compliance with applicable local, state, and federal laws and regulationsconcerning hazardous or solid waste management. Measures to protect workers and the environment would berequired before and during construction. This section describes measures to avoid and minimize direct andindirect impacts identified for Alternatives B2 and B4. Mitigation is not proposed because all state and federallaws can be met.5.17.8.1 AvoidanceBased on the location of existing and potential contamination sites and regulated materials issues, there are nomeasures that entirely avoid the impacts.5.17.8.2 MinimizationAlthough there are no measures that would avoid encountering subsurface contamination or generating wastematerials, the following preventive measures can be used during construction to minimize any potential costincreases or construction schedule delays. The following measures will help to minimize the impacts fromsubsurface contamination and waste materials.Coordination with Rhode Island Department of Environmental ManagementTo minimize the construction impacts from known release areas, response plans would be developed incoordination with RIDEM and in accordance with federal and state regulations.Preliminary InvestigationsAlternatives B2 and B4 would involve acquiring numerous properties and demolishing buildings, includingthose with commercial and industrial histories. Just as with the process RIAC already has in place with theCompleted and Current Part 150 VLAPs, due diligence in the form of environmental site assessments will beconducted after acquisition and before demolition of the properties. Specifically, preliminary investigations ofeach property would be conducted to assess and prevent the direct impacts of demolishing buildings containingACM and/or LBP. Preliminary investigations may include a Phase 1 Environmental Site Assessment prior tocommercial or industrial property acquisition, pre-demolition Inspection/Transaction Screen for ACM, LBP, orregulated waste materials, and any follow-up investigations required to address Recognized EnvironmentalConditions identified during Phase 1 Site Assessments. Additionally, during the design of the PreferredAlternative, properties where releases have been identified but not fully characterized (such as the Truk-AwayLandfill) 454 may also require additional investigation to further define the limits of contamination.454 The Department of Administration is responsible for the Truk-Away Landfill. A Site Investigation Report was submitted to the RIDEM on September 18,2008 for the Truk-Away Landfill by EA Engineering, Science and Technology, Inc. RIDEM has not commented on this report or the remedial alternativescontained therein as of the time of this filing.Chapter 5 - Environmental Consequences 5-268 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
