12. 310 CMR 40.0191 Response Action Performance Standard (RAPs) (3) The application of RAPS shall be protective of health, safety, public welfare and the environment and shall include, without limitation, in the context of meeting the requirements of this Contingency Plan, consideration of the following: – (e) eliminating or reducing, to the extent practicable and consistent with response action requirements and objectives, total energy use, air pollutant emissions, greenhouse gases, water use, materials consumption, and ecosystem and water resources impacts resulting from the performance of response actions through energy efficiency, renewable energy use, materials management, waste reduction, land management, and ecosystem protection. 10/21/201412

13. 310 CMR 40.0858 Detailed Evaluation Criteria (for Remedy Selection) the remedial action alternatives identified by the initial screening shall be evaluated using the following criteria: – (4) The comparative costs of the alternatives, including: (b) costs of environmental restoration, potential damages to natural resources, including consideration of impacts to surface waters, wetlands, wildlife, fish and shellfish habitat; and (c) the relative total consumption of energy resources in the implementation and operation of the alternatives, and externalities associated with the use of those resources, including greenhouse gases and other air pollutants. 10/21/201413

14. 2014 Greener Cleanups Guidance Promotion of greener cleanups consistent with Commonwealth’s mandates to improve energy efficiency, reduce emissions and expand the use of renewable energy resources where practicable. Voluntary consideration. The includes addressing five core elements or factors for reducing the environmental footprint of a cleanup. Greener cleanup considerations may not be used to override any requirement to implement a remedy to achieve the timely elimination, mitigation or prevention of such conditions. Users determine specific cleanup phase/response action for application. MassDEP advocates for the use of the ASTM Standard Guide for Greener Cleanups in addition to other available resources. 10/21/201414

15. 2013 USEPA Memo of Encouragement Assistant Administrator OSWER “[I]n the Agency’s pursuit of a cleaner, safer environment, I recommend that the regions and OSWER programs facilitate and encourage use of ASTM’s Standard Guide for Greener Cleanups in your efforts to implement greener cleanup practices.” 1510/21/2014

16. Available Guidance Resources Several guidance documents and implementing tools that have been developed by outside professional organizations: – United States Environmental Protection Agency (USEPA), August 2009, Principles for Greener Cleanups (US EPA Office of Solid Waste and Emergency Response) – USEPA, August 2014, CLU-IN | Strategies & Initiatives |Green Remediation Focus (http://cluin.org/greenremediation/)http://cluin.org/greenremediation/ – ASTM International, November 2013, Standard Guide for Greener Cleanups, E2893-13 – The Interstate Technology and Regulatory Council (ITRC), May 2011, Technology Overview, Green and Sustainable Remediation: State of the Science and Practice (GSR-1) – ITRC, November 2011, Technical/Regulatory Guidance, Green and Sustainable Remediation: A Practical Framework (GSR-2). 10/21/201416

17. OVERVIEW ASTM Standard Guide for Greener Cleanups  Structure  Only addresses green remediation  Fundamental core is selecting Best Management Practices (BMPs)  Flexible evaluation process A.Qualitative Evaluation – BMP selection B.Quantitative Evaluation (numerical assessment) – Footprint Analysis + BMP, or – Life Cycle Assessment + BMP  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 10/21/201417

18. Best Management Practices Best Management Practice (BMP) – Activity that reduces the environmental footprint of a cleanup activity – ASTM developed a comprehensive list BMPs NOT... 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 10/21/201418

19. SELECTING BMP’s ASTM Guide - BMP Table Task Group compiled table with over 160 BMPs ASTM provides 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 (LSPA Tech Practices) User can sort the Excel table by technology, core element or category 10/21/201419

20. BMP Process “Five Steps to Greening Cleanups” 1. Opportunity Assessment 2. BMP Prioritization 3. BMP Selection 4. BMP Implementation 5. BMP documentation

21. 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

22. ASTM BMP Table 2210/21/2014

23. Example P&T Selection from BMP Table 10/21/201423

24. 2. BMP Prioritization Identify BMPs with the greatest potential for reducing the environmental footprint and prepare prioritized list

25. BMP Selection – 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

26. 3. BMP Selection Unless a compelling reason to do otherwise, select each BMP from Step 2 for implementation – Document those that are not selected What is a “compelling reason to do otherwise”? – Substantive issues associated with applicability, implementation, impracticability and cost

27. BMP Selection – Step 3 Selection & Implementation  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

28. 4. BMP Implementation Again, document BMPs that can not be implemented and why

29. BMP Selection – 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

30. 5. BMP Documentation Record BMPs implemented Explain why BMPs from Steps 3 & 4 were not implemented (if any)

31. BMP Case Study No. 1 Future site use not defined Status: Remedy Selection – remedial excavation/backfill with engineered barriers and institutional controls BMP Opportunity Assessment Conducted (no QE) Summary tables prepared: – Potential BMPs – Prioritization of BMPs – Selection of BMPs – No Implementation at this stage 10/16/201331 SAMPLE

32. BMP Case Study No. 1 Selected BMPs: – Target Treatment Zones and select appropriate performance standard to minimize volume, tuck trips, emissions, etc. – Use nearby clean backfill – Use local staff/contractors – Use local biodiesel – Implement idle reduction – Establish green requirements for subcontractor selection. 10/16/201332
