Article 3 of 3 - Environmental Site Assessments (ESAs) are critical for managing environmental risks and ensuring the safety of properties over time. While most people are familiar with Phase I and II ESAs, there are actually six phases in total.
Phase III ESA, or Delineation, includes additional intrusive testing and a plan to mitigate environmental issues. It characterizes the size and source of contamination, develops a plan to address identified contaminants, involves regulatory authorities for cleanup, and ensures proper remediation and compliance.
Phase IV ESA, or Remedial Action Plans (RAPs), builds upon findings from prior assessments (Phase I and Phase II) that confirm the presence or absence of contaminants and their extent. The focus is on developing detailed plans for addressing contamination, and without a well-defined RAP, it’s challenging to proceed with site cleanup.
Phase V ESA, or Implementation and Evaluation, involves executing the planned remediation actions, conducting a thorough assessment after remediation to verify compliance with cleanup goals, and preparing a Record of Site Condition (RoSC) or Certificate of Clearance if the site meets regulatory standards. Successful completion of Phase V ensures that the site is safe for its intended use.
Finally, Phase VI ESA, or Long-Term Monitoring, involves ongoing monitoring and maintenance of the site after remediation to ensure long-term environmental protection and compliance.
Remember that all six phases of ESAs are crucial for managing environmental risks and ensuring the safety of properties over time.
