(c) was relied upon in the preparation of the risk assessment.

 

 

(ii) Risk Assessment Objectives

State the objectives of the ecological risk assessment and include an indication of,

(b) the ability to meet those objectives.

 

(b) Receptor Characterization

 

Describe in detail the characteristics of every valued ecosystem component, both on and off the RA property, identified in the ecological conceptual site model.

 

(c) Exposure Assessment

  (i) Pathway Analysis

Describe in detail every exposure pathway identified in the ecological conceptual site model. Justify which exposure pathways are incomplete.

 

 

(ii) Exposure Estimates

For every complete exposure pathway, state,

 

 

 

(a) the relative frequency and duration of actual or potential exposures;

 

 

 

(b) the relative magnitude of exposure to the valued ecosystem components, using measured contaminant exposure concentrations or concentrations predicted through fate and transport modelling in a manner compatible with that used in the human health risk assessment; and

 

 

 

(c) given the uncertainty described under the heading of “Problem Formulation”, how does this uncertainty affect the outcomes of the exposure assessments conducted under clauses (a) and (b).

 

(d) Hazard Assessment

 

State the potential adverse effects on the valued ecosystem components associated with their exposure to each contaminant of concern.

 

 

 

For each contaminant of concern,

 

 

 

(a) describe the relationship between the magnitude of exposure to the contaminant from each route of exposure and the probability of the occurrence of the adverse ecological effect identified in the Hazard Assessment;

 

 

 

(b) if the data permits, propose a toxicity reference value for each of the routes of exposure identified in clause (a); and

 

 

 

(c) analyze the sources of uncertainty in the data used to conduct the hazard assessment, including any gaps or variability in the data and state how such uncertainty could affect the assessment.

 

(e) Risk Characterization

  (i) Interpretation of Ecological Risks

For each contaminant of concern, having regard to the exposure assessment and the hazard assessment, state the risk attributable in respect of that contaminant to each exposure route for the valued ecological components on the RA property, using either a quantitative or qualitative analysis.

 

 

(ii) Quantitative Interpretation of Ecological Risks

A quantitative analysis that has been undertaken for a contaminant of concern must include the following:

 

 

 

  1. For each valued ecosystem component, provide a comparison of the toxicity reference value proposed in the “Hazard Assessment” to the exposure estimate proposed in the “Exposure Assessment” to derive an estimate of the degree of risk at the RA property in the absence of any measures that have been taken or are being proposed at the RA property which have the effect of reducing the risk from the contaminant of concern.

 

 

 

  2. Provide narrative to describe all magnitudes, comparisons and limitations relied upon to derive the risk under paragraph 1.

 

 

 

  3. Taking into consideration any risk management measures being proposed in the risk assessment, propose and justify an ecological standard for the contaminant, ensuring that the standard achieves the same level of protection for each valued ecosystem component that is intended to be achieved by the applicable full-depth generic site condition standard for that contaminant.

 

 

(iii)  Qualitative Interpretation of Ecological Risks

A qualitative analysis that has been undertaken for a contaminant of concern must include the following:

 

 

 

  1. Provide a justification for why a quantitative analysis was not undertaken.

 

 

 

  2. Describe the justification process being used as part of the qualitative analysis. The justification process includes a non-numeric characterization of risk and may include a numeric assessment of exposure or toxicity for screening purposes and risk prioritization.

 

 

 

  3. Taking into consideration any risk management measures being proposed for the RA property, propose and justify an ecological standard for the contaminant, ensuring that the standard achieves the same level of protection for each valued ecosystem component that is intended to be achieved by the applicable full-depth generic site condition standard for that contaminant.

 

 

(iv)  Special Considerations

If a RA property is,

 

 

 

(a) located within 30 metres of an “area of natural significance”, includes such an area, is adjacent to such an area or part of such an area, the justification for the ecological standard being proposed for the RA property must ensure that the standard is protective of the conditions that causes the area to be an area of natural significance; and

 

 

 

(b) subject to section 41 or 43.1 of the regulation, the justification for the ecological standard being proposed for the RA property must take into account the site conditions that make section 41 or 43.1 of the regulation apply to the RA property.

 

 

(v) Interpretation of Off-Site Ecological Risks

For each contaminant of concern, assess whether the ecological standard being proposed for the RA property is likely to result in a concentration greater than the applicable full depth site condition standard at the nearest ecological receptor located off the RA property and, if this is the case for any contaminant, specify the contaminant, the applicable site condition standard for that contaminant and the property where the ecological receptor is located and describe the ecological receptors that may be impacted.

 

 

(vi)  Discussion of Uncertainty

Having regard to the discussions of uncertainty under headings “Exposure Assessment” and “Hazard Assessment”, state how such uncertainty could affect the interpretation of risk advanced in this report section and the need to manage such risks.
