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

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
