“using, conserving and enhancing the community's resources so that ecological processes, on which life depends, are maintained, and the total quality of life, now and in the future, can be increased”
The core objectives of the strategy are:
a path of economic development that safeguards the welfare of future generations

conceptual site model for the site under consideration
related to potential contaminants at the site
environmental and socioeconomic impacts and burdens and to maximise economic and social values
utilised to facilitate planning of sustainable site assessment as this process proceeds through various phases
a sustainable remediation strategy to mitigate potential risks posed by complete or (potentially complete) exposure pathways identified in the CSM
tier of risk assessment to determine if it is more sustainable to continue with higher tiers of risk assessment or progress to remediation

Planning sustainable SAR Assessment of site contamination NEPM Numerous references economic, social and environmental aspects:
Date November 2015 A presentation to ACLCA SA 21
Volume 1 Section 6 relates to assessment of site contamination principles Principle 16 relates to options for site clean-up and/or management. ASC NEPM amendment of 2013 included insertion of: “When deciding which option to choose, the sustainability (environmental, economic and social) of each option should be considered, in terms of achieving an appropriate balance between the benefits and effects of undertaking the option”
Planning sustainable SAR Using tools in the planning process A range of tools, metrics and methods are available for undertaking an evaluation, screening and selection of appropriate sustainable remediation methodologies
Date November 2015 A presentation to ACLCA SA 22
Planning sustainable SAR Role of site contamination auditor Guidelines for the site contamination audit system are under revision. July 2015 draft provides additional guidance on the aims of the audit system to provide:
consideration of financial, social and environmental aspects of site contamination assessment and remediation”
Date November 2015 A presentation to ACLCA SA 23
The draft guidelines indicate that auditors are expected to:
carrying out an audit;
the auditor to make appropriately informed risk based decisions in accordance with the guidance provided in the ASC NEPM;
auditor to make that decision;

Conclusions Sustainable Site Assessment and Remediation The concept of Sustainable Development is well established and has been at the core of Australian environmental legislation for over two decades. Fundamental to this is the need to consider social, economic and environmental aspects in planning and implementation of works to address
Our understanding has now developed such that we have the tools, methods, appreciation and decision making processes to undertake site assessment and remediation which meets our needs but does not compromise the ability of future generations to meet theirs.
Date November 2015 A presentation to ACLCA SA 47
Now all we have to do is implement and improve them!
