The tiered environment risk assessment process is a systematic approach to evaluate and manage environmental risks. It involves several key requirements to ensure a comprehensive assessment. Here are some general steps and considerations:
1. Initiating the Risk Assessment: This step involves submitting a Pre-Submission Form (PSF) to the Ministry of the Environment for review. The PSF includes property characterization and receptor characterization information.
2. Preparation of a Risk Assessment Report: This step entails conducting a risk assessment and drafting a risk assessment report. The report should include information on human health risk assessment (HHRA) and ecological risk assessment (ERA).
3. General Guidance for Conducting Risk Assessments: This section provides guidance on conducting risk assessments to support filing a Records of Site Condition (RSC).
4. Requirements Specific to Human Health Risk Assessment (HHRA): This section outlines specific requirements for assessing risks to human health.
5. Requirements Specific to Ecological Risk Assessment: This section outlines specific requirements for assessing risks to the environment.
6. Risk Management: This section addresses risk management strategies for both human health risk assessment and ecological risk assessment.
7. Alternative Risk Assessment Procedures: This section provides information on alternative risk assessment procedures that may be applicable in certain situations.
8. Risk Assessment Submission and Review Process: This section explains the submission and review process for risk assessments.
9. Publications on Human Health Risk Assessment and Ecological Risk Assessment: This section provides additional resources and publications related to risk assessments.
Please note that the specific requirements and processes may vary depending on the jurisdiction and regulations in place.
