The first step in the Terrestrial Ecological Evaluation process is to determine if the site (area where contaminants have come to be located) has the potential to pose a risk to wildlife or plants, or affect the soil biota at the site.
Certain site circumstances provide an exclusion from any further ecological evaluation at a site because the contaminants either have no pathway to harm the plants or animals, e.g. they are under buildings or deep in the ground; or there is no habitat where plants or animals live near the contamination; or finally, the contamination does not occur at concentrations higher than is found naturally occurring in the area.
If a site meets any one of these primary exclusions, then the ecological evaluation is complete. If a site does not qualify for an exclusion, the evaluation process must be continued to either:
Make a determination about whether a simplified or a site-specific evaluation is required; or
Follow the links to the Primary Exclusion you would like to review:
Exclusion 1 - Contaminant Analysis
Exclusion 2 - Exposure Pathway Analysis - Incomplete Pathway
Exclusion 3 - Exposure Pathway Analysis - Area of Contiguous Undeveloped Land
Exclusion 4 - Contaminant Analysis - Natural Background
