It’s about maintainingthe delicate balance betweenProfit, People and Planet:the new corporateTriple Bottom Line

Sustainable Organizations : What are the Drivers?

Development of sustainable projects and organizations requires the management and cohesion of conflicting priorities: Profit: Corporate and shareholder value, stakeholders, industry, bankers People: Employees, Consumers, Communities, Countries (governments) Planet: Meeting global and local agreed-upon environmental standards

How to manage the pressure?

ORGANIZATION

Rising Stakeholder Expectations

Growing Complexity of Sustainability Issues

Multiplication of Principles, Indicators,

Guidelines, etc.

Sustainability: Two Levels of Application

1. To integrate sustainability principles in organizational management:BenchmarkingSustainability corporate planCarbon-neutral strategiesCommunity involvementEco-efficiency

2. To integrate sustainability at the project level:Decision support toolsLife-cycle analysisGHG inventoryEco-efficiencyEvaluation of social impacts

GoldSET© : a Tool to Help Integrate SD at the Project Level

GoldSET ©A Sustainability Support Decision Tool developed to help project managers and engineers:

1. Embed the Triple Bottom Line principles at the project level (bottom-up approach)

2. Manage conflicting pressures from various stakeholders

3. Make transparent and impartial decisions

4. Reduce the overall economic impacts through optimization

The best approach from a sustainability standpoint is based on: The biggest, most balanced triangle. Highest performance in each dimension Balanced performance between all dimensions Local specificities must be considered in selecting the option

Project Description Presence of a diesel plume covering approximately 20,000 m2

Apparent thickness ranges from 5 cm to 2 m Potential for off-site impacts Free phase product located in fractured bedrock

Contaminated Area

Yard

Case Study : Contaminated Yard

Objectives & Concerns1. Minimize expansion and

migration of LPH and dissolved phase plumes

2. Prevent off-site migration3. Avoid potential litigation

Case Study : A First Paradigm Shift!

The path that led to new investigations:• Unsatisfactory results from the Extraction program (cost vs. results)• Client’s desire to go forward with sustainability activities

The performance of five different remedial technologies were explored with GoldSET:

1. Interceptor Sumps2. Interceptor Trench3. MPE (Multi-Phase Extraction)4. Well-Based Hydraulic Barrier5. In-Situ Treatment by Oxygenation Barrier

The performance of the technologies in each aspect results from the integration of the scores for each indicator

Three options seem to perform better based on the results from the first iteration

Case Study : A First Paradigm Shift!

GoldSET: A First Paradigm Shift!

Second Iteration GoldSET allows the refinement of the evaluation by deselecting options

When comparing only the three best options from the first iteration, it became obvious that the Hydraulic Barrier was underperforming when compared to the other two options

The option was ignored and testing took place with the other two

A detailed analysis of the indicators showed that the differentiation came from an underperformance in seven different aspects

It’s the integration of the performance for each of the indicator that sums up the overall performance of each option

Pilot Test Findings and a Second Paradigm Shift

Data analysis from MPE testing showed erratic behaviour of the LNAPLthicknesses (well screen submerged and increase in LNAPL thick.) This observation challenged the way we interpreted diesel transport

with a water table fluctuating between the overburden and the fractured bedrock

Pilot Testing for the oxygenation of groundwater showed that biodegradation activities were occurring underneath the site

Based on the new conceptual model, the monitoring for natural attenuation was considered in the subsequent evaluation of options

November 19, 2010 28

Pilot Test Findings and a Second Paradigm Shift

The natural attenuation option was evaluated and considered to be the preferred remedial option, pending collection additional data

A Tiered Approach with GoldSET

• Preliminary evaluation• Qualitative criteria• Indirect stakeholder involvement

Tier 1

• Semi-quantitative evaluation• First order of magnitude estimations• Stakeholder consultations

Tier 2

• Detailed evaluation• Quantification of key criteria based on modeling,

life-cycle/cost-benefit analyses• Extensive stakeholder consultations

Tier 3
