Introduction

This framework represents a risk assessment process. It is based on Australia's National Environment Protection (Assessment of Site Contamination) Measure (NEPM) 1999

This involves three tiers - Tier 1 is found on the Introductory Risk Assessment page. Descriptions of the tasks involved in Tiers 2 and 3 can be found by clicking on the appropriate stage in the figure below. 

Note that the Initiation stage is an Introductory RA activity and is not undertaken in an Advanced RA. The Risk Management Decision stage has the same description for all three tiers.

Problem Identification Receptor Characterisation Risk Characterisation Exposure Assessment Toxicity Assessment This is the framework for the ERA process.  The figure has links to each stage of the ERA.
