Tier 1 Preliminary Site Investigation Includes Site Owners Potential sources Potential receptors Government Regulators Available site samples compared to levels (e.g. guideline levels) Detailed Site Investigation Includes Map contamination on and off site interaction with potential receptors on and off site Tiers 2 and 3 Site owners Site Specific and Off Site Risk Assessment Catchment Manager(s) Includes ecological risk assessment Other Source Industries in Catchment Potentially Affected Local Communities Management Response Includes Site owners No Action Catchment Manager(s) Contain Contamination Remediate Contamination Other Source Industries Destroy or Dispose of Contaminated in Catchment Waste Generated Other Potentially Undertake Management Actions Affected Stakeholders as appropriate Report on and Review Management Response Figure 1 Overview of the approach taken in this Guidance – Investigation This Guidance recognises that a wide of circumstances exist for contaminated sites and that site specific approaches will be necessary. Commonwealth agencies should adopt a staged approach to assessing and managing potential PFOS/PFOA contaminated sites, consistent with the ASC NEPM tiered assessment, to inform risk management decisions. A flowchart based on the approach contained in the ASC NEPM approach is presented in Figure 2 and this includes an indication of how the ASC NEPM steps may broadly fit with the investigate, diagnose or response elements of this Guidance.
