7Why Green and Sustainable Remediation (GSR)?
Reduced impacts• Emissions/
greenhouse gases (GHGs)• Energy/Water/Waste• Ecosystems
Simplified, reproducible results• Quantify desired metrics
Improved stakeholder engagement• Community benefited from trails installed
on new cap cover to river• Educational opportunities • Collaboration with local college

GSR PlanningEstablish GSR Goals
25
Key consideration of sustainable remediation
GSR stakeholders are typically a subset of the project stakeholders
New stakeholders may be identified solely on GSR interest
Engage at appropriate points during the cleanup project
For GSR, stakeholder involvement should be more frequent or to a greater effort than required by regulatory program
Includes GSR and non-GSR information
GSR PlanningStakeholder Involvement
26
Remedy Construction Example: distribution of information by monthly newsletter
Remedy Evaluation & Selection Example: interactive dialogue pertaining to limiting excavation
Stakeholder involvement can be interpreted and fulfilled in many different ways
GSR PlanningStakeholder Involvement Examples
27
Establish metric(s) for each GSR goal Consider boundary conditions, funding,
contracts, schedule, experience Quantitative vs. qualitative metrics Some metrics identified in Table 4-1 of

87Brownfield Site (Level 3)Summary
Benefits of GSR approach• Triad process expedited investigation and
redevelopment, improved remediation • Community institutions were strengthened • Air emissions (including GHG) were reduced• Project catalyzed neighborhood revitalization and job
creation will reduce poverty Challenge to implementing GSR
• Weighting social, economic and environmental metrics was difficult
Lessons learned• Tool selection depends on amount of information
available and technologies being evaluated
88
Key Lessons from Case Studies
Flexibility: GSR process can be applied to a variety of sites, remediation phases and regulatory programs
Communication: Communication with stakeholders is critical to successful application of GSR
Assumptions: Because evaluation methods are new, users must understand the assumptions of the tools being used
Holistic: This holistic approach will minimize a project’s life cycle impacts
