What Triad Is

An innovative approach to conducting site assessment and remediation activities through 3 key elements

Strategic Project Planning Uncertainty Mgmt Dynamic Work Strategies Real-Time Measurement Technologies

4

Purpose of The Triad Approach

To provide technically defensible methodology for

managing project uncertainty

:  Site uncertainty (Sampling and Analysis)  Decision uncertainty 5

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.

6

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

Costs Saved

$2.5M

40-50% on analytical 35% 50% Not Determined 50% 10

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

A Holistic Approach

“Intensive” Project Planning Uncertainty Mgmt Conceptual Site Model Real-Time Measurement Technologies Dynamic Work Strategies

13

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 14

Conceptual Site Model (CSM)

16

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 17

19

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!

20

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 21

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 22

Comparison

 Traditional approach involves: – fixed sampling – repeat mobilizations – greater uncerta inty  Triad approach involves: – rapid field screening – reduction in uncertainty – front-end cost-loading – reduction in overall project cost 25

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 26

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 27

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” 31

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. 32

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 33
