GREENER CLEANUPS ESTIMATING ENVIRONMENTAL FOOTPRINTS USING SEFA SPREADSHEETS FOR ENVIRONMENTAL FOOTPRINT ANALYSIS Carlos Pachon, US EPA HQ (Superfund) October 28, 2014 Karen Scheuermann, US EPA Region 9
Purpose of SEFA Webinar Provide a basic understanding of SEFA Demonstrate general organization and specific functions of the SEFA worksheets SEFA Spreadsheets for Environmental Footprint Analysis Open forum for discussion of footprint analyses and advanced features in SEFA Notes: This webinar will be very technical, getting into the details of the SEFA worksheets Participants should already have a solid understanding of greener cleanups Participants should already be familiar with EPA’s Footprint Methodology Additional experience likely needed to run a footprint analysis on SEFA 2

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 Spreadsheets for Environmental Footprint Analysis EPA’s May 2013 Webinar discussed the Methodology in greater detail SEFA is a companion tool to EPA’s Footprint Methodology SEFA was originally posted on Clu-in April 2012 and updated August 2014 Find the Footprint Methodology and SEFA at http: //clu-in. org/greenremediation/methodology/index. cfm 4
The Role of Footprint Analysis in Greener Cleanups Green Remediation Goals in Cleanup Project (Client request, Contractual Requirement, Regulatory requirement, etc) Small cleanup project, or standard cleanup approach Large complex projects Quantify footprint, prioritize reduction targets SEFA Select and apply specific best management practices ASTM Standard Guide for Greener Cleanups (E 2893): • 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 5

Basics of SEFA is… a set of Excel workbooks developed by EPA Spreadsheets for Environmental Footprint Analysis 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
SEFA has been updated for ease of use and flexibility of application P P P Simplified and consolidated data entry Increased flexibility for user-specific inputs Graphical outputs in chart format Notes and instructions for all key features Acknowledgements to the following Tetra. Tech staff (past and present) who developed the original SEFA worksheets and made the current updates: Doug Sutton Mike Pavarini Rob Greenwald Calculator for groundwater well construction In this webinar we will focus on the features of the updated SEFA worksheets
SEFA in the context of Greener Cleanups Basics of SEFA Before SEFA After Run Footprint Analysis Identify Areas for Reduction Apply BMPs Achieve Footprint Reductions original clean-up ––––––––––> greener clean-up
These are the 7 steps recommended in EPA’s Footprint Methodology. S E F A Basics of SEFA in the context of EPA’s Footprint Methodology 1 Set Goals and Scope of Analysis 2 Gather Remedy Information 3 Quantify Onsite Materials & Waste Metrics 4 Quantify Onsite Water Metrics 5 Quantify Energy & Air Metrics 6 Qualitatively Describe Affected Ecosystem Services 7 Present Results SEFA helps to quantify the metrics.

Basics of SEFA What if…. … I use reclaimed water instead of public water for dust control? Testing Alternative Scenarios ? … 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?

Demonstrate Key Features in SEFA Instructor opens SEFA Workbooks and demonstrates key features in the worksheets All three workbooks must be open at the same time 33
Demonstrate Key Features in SEFA Recap this has been a very simple site and remedy for a real site, can enter as much or as little detail as may be appropriate SEFA provides: format for data entry application of footprint conversion factors compilation of results The user: sets up structure of analysis to reflect site provides remedy inputs and documentation enters data directly into the spreadsheets Your footprint analysis can be tailored to specific questions at your site EPA is using SEFA at some of our cleanup sites and we welcome the use of SEFA by site owners and PRPs 34
Demonstrate Key Features in SEFA has additional features such as: Modeling renewable energy sources Instructions in SEFA provide full information on these features Tutorial illustrating all features of SEFA will be available on Clu-in Modeling carbon storage (e. g. from planting trees) Overriding fuel usage rates Representing alternative modes of transport and fuels These and other features in SEFA allow flexibility for accurately modeling specific site and remedy conditions. 35
