3. Challenge: To Lower the Environmental Footprint of Cleanup Projects *as defined by US EPA, aka Green Remediation The practice of considering all environmental effects of remedy implementation and incorporating options to minimize the environmental footprints of cleanup actions. Greener Cleanups* 3

6. Why A Standard? Codify best practices Define a process for reducing environmental footprint Provide a protocol for contracting purposes Provides “brand recognition” for greener cleanups Results in a transparent documented process that is reported publicly 6

7. ASTM Guide Origins In 2008, the EPA recognized a lack of guidance on how to implement green remediation. Consistent with Federal requirements the Agency researched the option of using voluntary standard development organizations. ASTM International, Inc. responded and agreed to initiate the development a Standard, which evolved to a Standard Guide. ASTM established a task group, comprised of professionals from consulting firms, regulatory agencies, law firms, and industry, and initiated the standard writing process in October 2009. Over the next 4 years the Task Group wrote the standard and took it through ASTM’s consensus-based approval process. In November 2013, ASTM published ASTM E2893-13 Standard Guide for Greener Cleanups. 7

8. Important Notice The ASTM Standard Guide for Greener Cleanup does not affect or supersede existing regulations and guidance issued pursuant to federal cleanup statutes, including for example, the CERCLA remedy selection process provided for in the National Contingency Plan (40 CFR part 300) and associated EPA Superfund guidance. 8

9. ASTM Framework for Greener Cleanup Greener Cleanup is a Process, not a Technology  Greener cleanup principles should be integrated into cleanup projects  Applied on a phase-by-phase basis  Is not just about remedy selection and green technologies “Only is green if it works”  Focus on how to incorporate BMPs into projects 9

10. The Basics Provides a step-by-step approach Flexible, with qualitative and quantitative options Includes reporting expectations Documentation must be publicly available (inhibits “green washing”) Environmental professional must lead the team and sign attestation that the standard was followed Designed to be the industry standard; particularly if adopted by regulatory agencies 10

11. ASTM Standard Guide Overview Fundamental core is selecting BMPs Flexible evaluation process Qualitative evaluation (BMP selection) Quantitative evaluation (numerical) Standard is applied on a phase-by-phase basis 1.Site Assessment 2.Remedy Selection 3.Remedy Design and Implementation 4.Operation, Maintenance and Monitoring 5.Remedy Optimization 11

14. Standard Management Practices are not Best Management Practices Standard Management Practice (not included because routine)  Considered industry standards and are truly basic in nature  Recycling office waste  Using compact fluorescent light bulbs  Minimizing paper use with electronic filing systems Best Management Practice  Activity that reduces the environmental footprint of a remedy  ASTM developed a comprehensive list BMPs 14

15. Best Management Practices  BMPs drive environmental footprint reduction  BMPs are organized on a technology or activity basis, but are applied based on the phase of the project  BMPs assigned to EPA’s five core elements  Energy  Air Emissions  Water Impacts  Material and Waste  Land and Ecosystem  ASTM considered establishing a “bar” for the minimum number of BMPs that need to be incorporated into a project in order for it to be considered Green; realized this was arbitrary, not defensible and partial to larger projects 15

16. BMP Process “Five Steps to Greening Cleanups” 1. Opportunity Assessment  Review master list of BMPs and retains those that warrant further consideration.  Consider BMPs not on the master list  Should be a pretty straightforward exercise 2. BMP Prioritization  Identify BMPs with the greatest potential for reducing the environmental footprint and prepare prioritized list 3. BMP Selection  Unless a compelling reason to do otherwise, select each BMP from Step 2 for implementation  What is a “compelling reason to do otherwise”?  Substantive issues associated with applicability, implementation, impracticability and cost 4. BMP Implementation  Document BMPs that can not be implemented and why 5. BMP Documentation and Reporting  Record BMPs implemented  If BMPs from Steps 3 & 4 were not implemented, explain why 16

17. BMP - Step 1 Opportunity Assessment Greener Cleanup BMP Table Task Group painstakingly compiled table with over 160 BMPs ASTM intends to provide the table in Excel format as an “Adjunct” Arranged by category, core element and technology  10 Categories (e.g., power & fuel, materials, vehicles…)  5 Core elements  11 Technologies (e.g., SVE, P&T, excavation…) User strongly encouraged to add BMPs to the table User can sort the Excel table by technology, core element or category 17

19. Example Selection from BMP Table

20. BMP Step 2 - Prioritization  Supplement P&T system with plant based extraction  Use variable frequency drives  Operate system in off-peak hours  Install amp meters to evaluate consumption rates  Use gravity flow where feasible  Purchase renewable energy credits  Use on-site generated renewable energy  Use excess steam as an energy source 20

21. BMP Step 3 - Selection  Supplement P&T system with plant based extraction  Use variable frequency drives  Operate system in off-peak hours  Install amp meters to evaluate consumption rates  Use gravity flow where feasible  Purchase renewable energy credits  Use on-site generated renewable energy 21

22. BMP Step 4 - Implementation  Supplement P&T system with plant based extraction  Development changed and area is now paved eliminating space for plants  Use variable frequency drives  Operate system in off-peak hours  Install amp meters to evaluate consumption rates  Use gravity flow where feasible 22

23. BMP Step 5 - Documentation Include tables generated in Steps 1 through 4 Follow requirements in Section 8 and the example Technical Summary Form outline in Appendix X2 23

24. Section 7: Quantitative Evaluation Overview  Most applicable to large and complex site  Types of quantitative evaluation  Footprint Analysis  Life Cycle Assessment  Seven step process  Uses for quantitative evaluation  Opportunity Evaluation  Technology Evaluation  Metrics for BMPs

25. Section 7: Quantitative Evaluation Approach Define the scope of the assessment and system boundaries Collect and organize input information for analysis Run calculations, for example using EPA’s SEFA* or other tool Conduct a sensitivity analysis, identify target footprint elements Use quantitative evaluation findings to select BMPs (Section 6) 25

26. Interpreting Results: Targeting Areas for Footprint Reduction Baseline Footprint Key contributor is diesel fuel combustion during truck transport of waste off-site Optimization #1 → no idling during loading As en example: We’ll focus our optimization efforts on particulate matter emissions. Optimization #2 → no idling during loading → use particulate filters 26

27. Baseline → air stripping with GAC → discharge to POTW Optimization #1 → enhance air stripping → eliminate GAC Optimization #2 → all the above (Opt #1) → discharge to surface water Optimization #3 → all the above (Opt #2) → install renewable energy continued Interpreting Results: Targeting Areas for Footprint Reduction

28. Section 8: Documentation and Reporting Step 1: Document for each phase BMP Summary Tables  List applicable BMPs, prioritized by anticipated environmental benefit  Identify those implemented  Include rationale for those not implemented  Identify BMPs required by law or regulation Quantitative Evaluation Report, if applied 28

29. Section 8: Documentation and Reporting Step 2: Make publicly available Technical Summary (Appendix X2 form)  General Information  Environmental Footprint Reductions BMP Summary Tables and Quantitative Evaluation Report, if applicable (for each phase) Self-Declaration 29

30. Section 8: Public Availability Public repository Post on a website Submit to a regulatory agency, with prior agency consent ASTM will post on website. Contact Kate McClung at: kmcclung@astm.org 30

31. Section 8: Timing for Reporting Based on:  Needs of the user  Requirements or agreements with a regulatory program  Commitments through contractual agreements or with stakeholders Recommends results be reported after implementation of cleanup activities 31

32. Summary of Key Attributes Voluntary: Not mandating new cleanup evaluation Flexible: Guide vs. Practice Universal: Program neutrality facilitates implementation Transparent: Public availability of decisions & outcomes Tool: Appendix X3 BMP Table ASTM: Provides brand recognition 32
