Overview of The Triad Approach

1. Overview of The Triad Approach Presented to: Society of American Military Engineers Orange County Post Presented by: Bill Girolamo and Bill Musser Environmental Data Solutions Group, LLC

4. Strategic Project Planning Uncertainty Mgmt Dynamic Work Strategies Real-Time Measurement Technologies What Triad Is An innovative approach to conducting site assessment and remediation activities through 3 key elements

5. Purpose of The Triad Approach To provide technically defensible methodology for managing project uncertainty: • Site uncertainty (Sampling and Analysis) • Decision uncertainty

6. Is the Triad Approach New? • No, it introduces a more systematic process. • Is Triad simply expedited, accelerated, or streamlined site characterization? • No, it involves higher level planning resulting in expedited characterization & remediation.

7. History of Triad • Formerly Expedited Site Characterization (ESC) • Initiative started in 1980’s by the DOE • Objective to reduce Assessment & Remediation Costs • Driven by approximately 20 DOE sites on the NPLs • 1993 guidelines published as ESC • Triad Technical Regulatory Guidelines, 2003 • Developed by International Technology and Regulatory Council (ITRC), 40 States Participate (www.itrcweb.org) • Funded by DOE and USEPA • Utilized the ESC to develop Triad • USEPA takes lead role in the 2000s (www.triadcentral.org) • Evolves into a Federal/State Interagency Partnership

9. Triad Benefits Enhanced Stakeholder Alignment Improved Site Decision-Making Reduced Data Collection Costs Expedited Schedules Reduced Overall Project Timeline and Cost

10. Examples of Actual Project Savings • Source: www.triadcentral.org

11. Does Triad Increase Cost? • Common misconception: • Triad adds cost to the project • Triad front-loads cost for Site Investigation, but • Reduce additional field mobilizations • Minimize rework • Shorten overall timeline and cost to closure

13. “Intensive” Project Planning Uncertainty Mgmt Dynamic Work Strategies Real-Time Measurement Technologies Conceptual Site Model A Holistic Approach

14. Strategic Project Planning • Key components: Conceptual Site Model and Decision Logic Diagrams • Concurrence from all stakeholders • Continues through life of project • Value: Reduces costs through stakeholder concurrence, therefore reduces rework

17. Dynamic Work Strategies • Execute field work based on Decision Logic Diagrams and Real-Time Measurement Technologies • Utilize site characterization real-time field data findings to decrease uncertainty • O&M activities real time monitoring allows for optimization/reduced remediation • Value: Approach decreases uncertainty and costs

18. What We Used to See

19. What We See Now Slide adapted from Columbia Technologies, Inc., 2003

20. Real-Time Measurements • New technologies allow real time data collection • Per-sample cost is cheaper, but more qualitative before conducting analyses • Decreases uncertainty • Real time monitoring results in Dynamic Work Strategies • Value: Decrease in uncertainty results in better decision making!

21. Some Key Triad Best Practices • Robust Conceptual Site Model • Focus on Decision Uncertainty • Development of an Exit Strategy • Development of Decision Logic • Use of Dynamic Work Strategies • Use of Collaborative Data Sets

22. Key Aspects of Triad Execution Sample representativeness managed for data results extrapolated to decisions Demonstrations of Method Applicability (DMAs): for real-time measurement technologies and data management tools; Agency approval maybe necessary Collaborative data sets: Real Time information used in conjunction with traditional fixed laboratory analytical results

25. Comparison • Traditional approach involves: • fixed sampling • repeat mobilizations • greater uncertainty • Triad approach involves: • rapid field screening • reduction in uncertainty • front-end cost-loading • reduction in overall project cost

26. What Makes Triad Successful? Integrates key elements into a coherent package that restructures cleanup projects Shifts resource investment -- increases front end costs, but reduces total costs Process drives stakeholders to unified site understanding from the beginning The CSM facilitates the stakeholder consensus vision

27. Manage Decision Uncertainty to Achieve End Goals • Obtain answers to achieve end-goals to: • Meet regulatory concerns • Perform cost-benefit estimates • Support site closure and reuse • Unify stakeholders’ understanding to facilitate defensible and sustainable decisions

29. Triad Roll-Out Triad successfully implemented across the Country See summaries of 30 successful projects at: http://www.triadcentral.org./user/profile/index.cfm

31. Local Agency Adoption & Use • EPA Region 9 • DoD and Region 9 Management supportive, Triad used extensively • Assured correct decision making • Reduced cost and timeline on projects • DTSC • Trained by USEPA • Supports Triad, but no formal policy • RWQCB • Trained by USEPA • Supports Triad, but no formal policy • Limited roll-out at “test sites”

32. Local Agency Adoption & Use To Promote/Test Triad: Formal management support needed Shift workloads to accommodate Triad projects Caseworkers focus on key Triad sites to reach exit strategy in timely fashion.

33. Adoption at Non-DOD Sites • Successfully applied to numerous private sector sites • Triad does not work when • Teams refuse to collaborate • Property owners or PRPs are uncooperative • Stakeholders change minds, do not honor agreements made during strategic planning

35. Summary • Triadis an innovative approach focusing on • Strategic Project Planning • Dynamic Work Strategies • Real-Time Measurement Technologies • The purpose of Triad is to Manage Project Uncertainty • The benefits of Triad are • Enhanced Stakeholder Alignment • Reduced Data Collection Costs • Expedited Schedules • Improved Site Decision-Making • Reduced Overall Project Timeline and Cost
