Phase I FAQ

What is a Phase I ESA and why do I need one?

A Phase I ESA is an assessment for environmental risk management tool used by buyers, sellers, financiers, insurers and regulators to assess and manage for potential contamination on or around a property.

How long does a Phase I ESA take and how much does it cost?
Our Phase I ESAs have an average turnaround of 10 business days. Pricing is specific to the location but we can provide you a cost in our initial discussion.
Do you need to take samples for a Phase I ESA?
No. The first step is determining if a site has potential for contamination that presents a risk to the environment or human health. We use the historical information for a property to determine areas that are most likely going to have been affected by historical or current activities, as well as to determine the substances that may be present, and where those contaminants may be present such as soil, groundwater, or soil vapour. 
What are the benefits of hiring a qualified environmental professional for a Phase I ESA?
It is a requirement to have contaminated sites assessment performed and overseen by qualified professionals in BC. The professional completing the assessment must have the Right to Practice governed by one of the Regulatory bodies of the Province (ex. BC Institute of Agrologists, Engineers and Geoscientists of BC). This ensures a standard of education and ability within the set of available practitioners.
What are the limitations and risks of a Phase I ESA?
Phase I ESAs rely upon published reports, records, historical documents and a site visit. While thorough, the scope of this assessment does not include environmental sampling and so can only provide recommendations based on historical and current data as no new data about environmental quality is generated. If warranted, sampling and analysis may be recommended through a Phase II ESA to determine if potential contaminants of concern are present. 
How can I prepare for a Phase I ESA and what documents do I need to provide?
After engaging Sage, you can provide us with applicable company records, buildings and site details, historic environmental reports, access to the property for investigation, and contact information for people familiar with the history of the Site. We will provide some tools like fillable forms to complete related to site history and agency letters for signing to allow us to conduct record searches related to the property.
What happens after the Phase I ESA?
We will provide you with the assessment and any recommendations including next steps. Often the completion of the Phase I ESA is all that is needed to control environmental risks. Sometimes further investigation such as Phase II ESA, including drilling and sampling is recommended. Next steps are often based on a risk tolerance of yourself and/or your financier.

Detailed Site Investigations (DSI)

Detailed Site Investigations (DSI)

Phase II Environmental Site Assessment and Stage 2 Preliminary Site Investigation that identify contamination often recommend a Detailed Site Investigations (DSI).  A DSI finds the extents of contamination to quantify impacts to soil, groundwater and soil vapour. The details on contaminant type, severity and amount will inform further remediation or risk assessment options.  A DSI may include off-Site investigations if contamination has moved past the Site boundaries. A DSI is required prior to remediation for any type of permit release or Certification Document from the Ministry of Environment (BC ENV).
