  4. SEFA Overview of Greener Cleanups • Green Remediation: The practice of considering all environmental effects of remedy implementation and incorporating options to minimize the environmental footprints of cleanup actions • Goal of Footprint Analysis: Identify the most significant contributors to a project’s environmental footprint and better focus efforts to reduce them • EPA published Footprint Methodology February 2012 • SEFA is a companion tool to EPA’s Footprint Methodology • SEFA was originally posted on Clu-in April 2012 and updated August 2014 SpreadsheetsforEnvironmentalFootprintAnalysis EPA’s May 2013 Webinar discussed the Methodology in greater detail Find the Footprint Methodology and SEFA at http://clu-in.org/greenremediation/methodology/index.cfm

  5. SEFA The Role of Footprint Analysis in Greener Cleanups Small cleanup project, or standard cleanup approach Green Remediation Goals in Cleanup Project (Client request, Contractual Requirement, Regulatory requirement, etc) Select and apply specific best management practices Large complex projects Quantify footprint, prioritize reduction targets • ASTM Standard Guide for Greener Cleanups (E2893): • Codifies best practices and defines a process for reducing environmental footprint • Includes over 160 BMPs and outlines process for straight BMP application or use of quantification • Useful protocol for contracting purposes • Results in a transparent documented process that is reported publicly

  8. Basics of SEFA SpreadsheetsforEnvironmentalFootprintAnalysis • SEFA is… • a set of Excel workbooks developed by EPA • designed for conducting environmental footprint analyses at clean-up sites • compatible with EPA’s Footprint Methodology • set up in “blank slate” template format • structured for inputting data, running calculations, and organizing outputs originally designed for internal EPA use placed on EPA web page for public access updated in August 2014

  9. SEFA has been updated for ease of use and flexibility of application P Simplified and consolidated data entry Acknowledgements to the following TetraTech staff (past and present) who developed the original SEFA worksheets and made the current updates: Doug Sutton Mike Pavarini Rob Greenwald P Increased flexibility for user-specific inputs P Graphical outputs in chart format P Notes and instructions for all key features P Calculator for groundwater well construction In this webinar we will focus on the features of the updated SEFA worksheets

  10. Basics of SEFA SEFA in the context of Greener Cleanups SEFA Before Run Footprint Analysis Identify Areas for Reduction Apply BMPs Achieve Footprint Reductions After original clean-up ––––––––––––––––––––> greener clean-up

  11. Basics of SEFA These are the 7 steps recommended in EPA’s Footprint Methodology. SEFA in the context of EPA’s Footprint Methodology Set Goals and Scope of Analysis 1 Gather Remedy Information 2 SEFA Quantify Onsite Materials & Waste Metrics 3 SEFA helps to quantify the metrics. Quantify Onsite Water Metrics 4 Quantify Energy & Air Metrics 5 Qualitatively Describe Affected Ecosystem Services 6 Present Results 7

  12. Basics of SEFA Three Excel Workbooks Main Workbook Input Workbook Calculations Workbook • User enters basic site and remedy information • User sets up analytic structure • User enters data for remedy activities • Workbook compiles • the intermediate results • No data entry by user in this workbook • Workbook makes the footprint calculations Workbook provides summary of results The user sets up the analytic structure The user enters information about the remedy The workbooks exchange data and process the results

  13. MAIN WORKBOOK User sets up the basic structure of the footprint analysis User may identify up to six Remedy Components … Site Name and Remedy Name … to reflect stages of the remedy

  14. MAIN WORKBOOK User sets up the basic structure of the footprint analysis • The Remedy Components can be set up to differentiate among various aspects of the remedy. • different stages of the remedy • alternative remedy designs • specific remedy activities • separate years in the remedy Bioremediation Year 1 Pump and Treat Hazardous Waste Transport Bioremediation Year 2 Pump and Treat w/ UV Municipal Solid Waste Transport Bioremediation Year 3 Pump and Treat w/ Solar Power Remediation Materials Bioremediation Year 4 Pump and Treat w/ Re-injected GW Grid Electricity Close-out Year 5 Off-Site Services Personnel Transportation

  15. INPUT WORKBOOK User sets up the structure for data entry

  16. INPUT WORKBOOK User sets up the structure for data entry User sets up a data entry tab for each activity in the footprint analysis Up to 14 data entry tabs can be included in each footprint analysis.  Make a copy of the Input Template tab  Name the new tab to reflect the activity

  17. Basics of SEFA Conceptual Approach to Setting up SEFA Worksheets

  18. INPUT WORKBOOK Taking a closer look at the Input Template Color coding of the cells helps in data entry  drop-down menus  from look-up tables or calculated values  data entry by user pink blue yellow The pink and yellow cells provide user flexibility in data entry

  19. INPUT WORKBOOK User enters specific information about the remedy Link to Remedy Component Input Template Tab page 1 Personnel Transportation • Looks like lots of blank cells to fill in, but… • use only the cells that are relevant to the site • enter as much (or as little) detail as needed On-site Equipment Use and Transport User should note any assumptions and items that are screened out • Natural Gas • and • Landfill Gas On-Site Electricity Usage

  20. INPUT WORKBOOK User enters specific information about the remedy Input Template Tab page 2 Materials Use and Transport • Where do we get inputs for the footprint analysis? • Feasibility Study • Cost Estimate • Engineering Designs • Literature Search • Professional Judgment Waste Disposal and Transport Water Use User should provide references and supporting calculations

  21. INPUT WORKBOOK User enters specific information about the remedy Input Template Tab page 3 Off-Site Laboratory Analysis Other Voluntary Renewable Energy Use The data entry tabs make certain calculations such as fuel usage. Other Energy Use and Air Emissions Space for Notes, References, and Supporting Calculations Results of the data entry tabs are compiled in the Input Summary tab.

  22. INPUT WORKBOOK Link to the Input Summary tab This tab compiles the inputs and results from the data entry tabs User enters the names of the data entry tabs Subtotals are compiled for each data entry tab and (not shown) for each Remedy Component On-site diesel use Diesel & gasoline for transport The results are sent to the Calculations Workbook Three pages of compiled results Input Summary tab

  23. CALCULATIONS WORKBOOK Make footprint calculations Energy GHG NOx SOx PM HAPs Materials, Energy, Water, Waste, and Off-site Support Activities Units and Usage The Calculations Workbook receives results from the Input Workbook … … and applies footprint conversion factors. Seven pages of footprint calculations No data entry by the user in this Workbook … … but the user may access the intermediate results from the worksheets. Results are sent to Main Workbook

  24. MAIN WORKBOOK Summarize and present results Materials Waste This table compiles the results as recommended in EPA’s Footprint Methodology. Water Energy Air Emissions

  25. MAIN WORKBOOK Summarize and present results This chart is generated automatically in SEFA. SEFA generates basic charts for Energy, GHG, NOx, SOx, PM, and HAPs.

  26. MAIN WORKBOOK Summarize and present results • The user has access to intermediate results • in SEFA • understand contributors to the remedy footprint • target areas for footprint reduction The user can make charts like this from results in the Calculations Workbook.

  27. Basics of SEFA Testing Alternative Scenarios SEFA can be used to compare footprints for alternative scenarios What if…. ? … I use reclaimed water instead of public water for dust control? ? … I use biodiesel instead of conventional diesel? ? … I conduct more extensive site investigation, leading to reduction of the amount of contaminated soil sent to the landfill?

  28. Basics of SEFA SpreadsheetsforEnvironmentalFootprintAnalysis • SEFA is… • a set of Excel workbooks developed by EPA • designed for conducting environmental footprint analyses at clean-up sites • compatible with EPA’s Footprint Methodology • set up in “blank slate” template format • structured for inputting data, running calculations, and organizing outputs Can be set up to reflect any remedy design Automatically applies footprint conversion factors Compiles results consistent with EPA Methodology
