Sustainable Remediation Initiative 1 GSR Definitions Green Remediation

Sustainable Remediation Initiative 1

GSR Definitions � � Green Remediation (EPA) “the practice of considering all environmental effects of remedy implementation and incorporating options to minimize the environmental footprints of cleanup actions”. Sustainable Remediation (SURF) “protects human health and the environment while maximizing the environmental, social, and economic benefits throughout the project life cycle. ” Green and Sustainable Remediation (ITRC) “the site-specific employment of products, processes, technologies, and procedures that mitigate contaminant risk to receptors while making decisions that are cognizant of balancing community goals, economic impacts, and net environmental effects. ” Common and aligned focus on efficiency and effectiveness 2

Sustainable Remediation … � Is: ◦ Holistic, Process Focused, Flexible & Scalable, Site Specific, Fit for Purpose, Performance Based � Is NOT: ◦ New, Technology, Excuse to do nothing (or less), Prescriptive � Benefits: ◦ Maximizes benefits & minimizes costs (environmental, social, economic)-while still protecting human health and the environment ◦ Supports stakeholder participation & acceptance ◦ Provides the best remediation 5

Common SR Process Elements 1. Select appropriate stakeholder team 2. Define current project status: 3. Choose project goals, metrics, and tools: 4. Evaluate options for project: 5. Implement most appropriate option process to reach general consensus evaluate/update conceptual site model in SR terms: social, environmental, economic prioritize key issues, select boundaries, determine appropriate evaluation level develop options fit for future use of property and evaluate with weighted costs and benefits document, monitor, optimize 9

Increasing Data Needs SR Evaluation Levels LEVEL 3 Advanced Evaluation LEVEL 2 Simple Evaluation LEVEL 1 BMPs/Strategies

SR Example 11

Level 1 – List of BMPs • • Hand Wash no car washes nearby - have no money use biodegradable soap use rain water • • Car Wash car wash is close - have no time stop by on way home from work only stop when no line • No Action • save: water, time, money 12

Level 2 – Green Remediation Metric Greenhouse gases Water Time Waste No Action Hand Wash Car Wash Red = low performance Yellow = average performance Green = good performance

Level 2 –Sustainable Remediation Metric Greenhouse gases Water Time Waste Community acceptance Cost No Action Hand Wash Car Wash Red = low performance Yellow = average performance Green = good performance

Level 3 – values and weighting Metric Greenhouse gases (lbs) Water (gallons) Time (hours) Waste (lbs) Community acceptance Cost ($) Weight No Action Hand Wash Car Wash 1 0 3 5 1 0. 5 1 4 2 0 0 0 10 0 20 1 5 2 5 5 0. 1 3. 5 1 10

SEFA � Set of Excel workbooks developed by EPA for conducting environmental footprint analyses at cleanup sites � Compatible with EPA’s Footprint Methodology � Incorporates data on materials, waste, water, energy, and air � Structured for inputting data, running calculations, and organizing outputs 16

Sustainable Remediation Tool (SRT) TM � Use for remedy selection & optimization � Two levels of detail � Eight technologies � Metrics: ◦ Air emissions, GHG emissions, energy, cost, accident risk, change in resource use � Stakeholder scoring matrix http: //www. afcee. af. mil/resources/technologytransfer/ programsandinitiatives/sustainableremediation/srt/ index. asp
