Short description: EXTRACT: The ERA framework provides a structured approach for assessing the risks to ecology from chemical contamination in soils (a requirement under Part 2A (Contaminated Land) of the Environmental Protection Act 1990). The framework consists of a three-tiered risk assessment process: Tier 1 of the risk assessment is a screening step based on a comparison of chemical analyses of site soils with a soil screening value (SSV) for the contaminants of potential concern. Tier 2 uses a choice of tools (ecological surveys and biological testing) to gather evidence for any harm to ecological receptors (plant and animal species) present at the site. Tier 3 seeks to attribute the harm to the chemical contamination. It has been designed to establish whether pollutant linkages are likely to exist between the contamination and the designated ecological receptors; and gather sufficient information for making decisions regarding whether harm to these receptors is occurring or could occur in the future.
