In the vibrant city of Toronto, where development and growth are constant, ensuring the environmental integrity of properties is paramount. For property owners, real estate developers, attorneys, and land developers, understanding the intricacies of environmental site assessments is crucial. At Fisher Engineering Limited in Markham, we specialize in providing comprehensive environmental services, including Phase II Environmental Site Assessments (ESAs), to help navigate the complexities of site contamination and development. Our mission is to create Solid Foundations for livable environments, ensuring that our clients can build, develop, and manage properties with confidence.
What is the Purpose of a Phase II Investigation?
A Phase II ESA is a detailed investigation that goes beyond the surface to assess the subsurface environmental conditions of a site. This phase is triggered by findings from a Phase I ESA, which identifies Areas of Potential Environmental Concern (APECs) or Recognized Environmental Conditions (RECs). The primary purpose of a Phase II ESA is to characterize the nature and extent of contamination, if any, by collecting and analyzing soil and groundwater samples. This information is essential for determining the need for remediation or cleanup and for supporting development approval applications, such as filing a Record of Site Condition (RSC) with the Ministry of the Environment, Conservation and Parks (MECP).
In Toronto, Phase II ESAs are conducted in accordance with Ontario Regulation 153/04, which outlines the requirements for environmental site assessments. The process involves drilling boreholes, installing monitoring wells, and conducting laboratory analyses to assess the presence of contaminants of concern (COCs) in soil and groundwater. This comprehensive approach ensures that property owners and developers have a clear understanding of the environmental conditions on their site, which is vital for commercial, development, and remediation/cleanup processes.
What Triggers a Phase II ESA?
A Phase II ESA is typically triggered when a Phase I ESA identifies potential environmental hazards or APECs that require further investigation and evaluation. These hazards might include past uses of the property that could have led to contamination, such as industrial activities, underground storage tanks, or other potentially contaminating activities (PCAs). The Phase I ESA provides a preliminary assessment of these risks. If there is evidence suggesting actual contamination or a high likelihood of contamination, a Phase II ESA is necessary to gather more detailed information.
For instance, if a property in Ontario has a history of industrial use, such as manufacturing or fuel storage, a Phase I ESA might identify these past activities as APECs. A Phase II ESA would then be conducted to determine if contaminants like hydrocarbons or heavy metals are present in the soil or groundwater. This detailed analysis is crucial for informing remediation strategies and ensuring compliance with environmental regulations.
The Process of a Phase II ESA
The process of conducting a Phase II ESA involves several key steps:
1. Preparation and Planning: Before commencing on-site work, it is essential to review previous reports, prepare a sampling and analysis plan (SAP), and clear public and private underground utility services to avoid any potential hazards.
2. Site Investigation: This involves drilling boreholes and/or excavating test pits to collect soil samples and installing monitoring wells to assess groundwater conditions. The location of these boreholes and wells is carefully planned based on the APECs identified in the Phase I ESA.
3. Sampling and Analysis: Soil and groundwater samples are collected and analyzed in an accredited laboratory to determine the presence and concentration of contaminants. This data is critical for understanding the environmental condition of the site and for developing strategies for remediation if necessary.
4. Reporting and Recommendations: The findings from the Phase II ESA are compiled into a comprehensive report that outlines the environmental conditions of the site, any contaminants present, and recommendations for further action. This report is essential for property owners and developers seeking to move forward with development plans.
