2. www.clu-in.org/greenremediation 1 Environmental Footprint Analysis Evaluate the amount or intensity of the five core elements Apply footprint analysis to the largest and most complex clean-up sites Use results to target and reduce the greatest contributors to the footprint Core Elements Materials & Waste Energy Air Water Land & Ecosystems EPA’s Footprint Analyses are Aligned to Our Green Remediation Core Elements

3. www.clu-in.org/greenremediation 2 Environmental Footprint Analysis However, we do not conduct an impact assessment. In our Footprint Analyses we use some of the principles of a Life-Cycle Assessment. Impact assessments may be considered in future work by EPA in Green Remediation. We Use “Life-Cycle Assessment Thinking” in Our Footprint Analyses

4. www.clu-in.org/greenremediation 3 Environmental Footprint Analysis off-site activities: manufacturing energy production other support activities transportation to and from facility on-site activities (inside facility fence line) We include resource extraction wherever possible. We include on-site activities, transportation, and off-site activities. We do not include the manufacturing of on-site construction equipment or the building of off-site infrastructure. Boundaries of Our Environmental Footprint Analyses

5. www.clu-in.org/greenremediation 4 Environmental Footprint Analysis Common Remediation Materials and Services Encountered in Our Footprint Analyses Potable water PVC Steel Concrete Clay Granular activated carbon Emulsified vegetable oil Trees Fertilizers Potassium permanganate Hydroxide peroxide Acetic acid Zero-valent iron UV lamps Materials Solid waste disposal Hazardous waste disposal Laboratory analysis Wastewater treatment Reactivation of granular activated carbon Off-Site Services Gasoline Diesel fuel Natural gas Grid electricity PV cells Energy approx 40 common remediation materials or services

6. www.clu-in.org/greenremediation 5 Environmental Footprint Analysis Energy Total energy Grid electricity Air Emissions CO2 equivalents NOx SOx Particulates Air toxics May Include Other Contaminants Mercury Lead Dioxins Environmental Parameters Addressed in Our Footprint Analyses Water Local groundwater extracted Local potable water used Total water Waste Solid (non-hazardous) waste Hazardous waste Materials Refined materials used Unrefined materials used we include each of these parameters for reasons of global, regional, or local interest

7. www.clu-in.org/greenremediation 6 EPA Region 9’s Green Remediation Pilot Study In Our Green Remediation Pilot Study We Conducted Footprint Analyses on Clean-ups at Three Pilot Sites Constructing a bioreactor at Travis Air Force Base, one of the Pilot Sites in the Green Remediation Pilot Study Photo courtesy of Travis AFB Gained experience in estimating the environmental footprints of clean-ups Developed a library of resources for site remediation activities Constructed an analytic framework in spreadsheet format for use at other sites Posted results and resources on EPA web page at www.clu-in.org/greenremediation EPA HQ is using experience gained from the Pilot Study in the development of an EPA-wide methodology for footprint analyses at clean-up sites

8. www.clu-in.org/greenremediation 7 EPA Region 9’s Green Remediation Pilot Study Romic East Palo Alto – Pump & Treat CO2e Emitted (lbs) electricity production carbon regeneration wastewater treatment at POTW Example of results from an environmental footprint analysis that can be useful for targeting areas for footprint reduction.

9. www.clu-in.org/greenremediation 8 Develop EPA methodology for estimating environmental footprints must be practical for ease of application at active sites must provide information that is useful for site decisions Conduct streamlined footprint analyses at selected clean-up sites reduce the environmental footprint for remedies already in place provide information during analysis of remedy alternatives Apply principles of the footprint analysis program-wide Reducing the environmental footprints of our clean-up programs    Moving Forward with Footprint Analyses

10. www.clu-in.org/greenremediation 9 Results of Environmental Footprint Analyses at our Pilot Sites are Posted on EPA’s Web Page at: www.clu-in.org/greenremediation Questions and Comments to: Karen Scheuermann, EPA Region 9 scheuermann.karen@epa.gov The Environmental Footprint Analyses were conducted by EPA Region 9 and funded by EPA Headquarters Resources
