Terrestrial Ecological Evaluation Process- Exclusions


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

  Compare chemical concentrations in the soil to the Table 749-3 values.  If soil values do not exceed the table values, the evaluation is complete for those chemicals.

 

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
