Do you need a Phase I ESA?
We deliver timely and accurate Phase I ESA’s for the Okanagan region so you can satisfy your property financiers, buyers, and regulators sooner.
Stage 1 Preliminary Site Investigation (PSI)
Stage 1 Preliminary Site Investigation (PSI): Also referred to as a Phase 1 Environmental Site Assessment (ESA) is a method used to assist in determining potential environmental liabilities due to contamination on a site or property. This process involves a detailed review of land uses and history including a site visit, record searches, personal interviews and the evaluation of related information and reporting. This information is compiled and used to determine the potential of impact on a site due to contamination.
Stage 2 Preliminary Site Investigation (PSI)
Stage 2 Preliminary Site Investigation (PSI): Also referred to as a Phase II Environmental Site Assessment (ESA) these investigations involve environmental sampling and analysis to determine the degree of contamination and characterize the type of contaminant(s).
A Stage 2 PSI Involves:
- A review of existing background information including Stage 1 PSI
- Development of sample and investigation planning
- A site investigation that may include drilling or excavating to sample soil, water, and vapour
- Data interpretation and evaluation reporting
A Stage 2 PSI May Be Used To:
- Confirm the findings of a Stage 1 / Phase I Investigation
- Supplement previous Stage 2 / Phase 2 work
- Gather information in support of Remediation measures or site redevelopment
- Establish a baseline of environmental conditions for a further Detailed Site Investigation
- Provide a due diligence measure to determine compliance with corporate stewardship
Remote location spill remediation and restoration.
Sage Environmental Consulting Ltd. was retained to provide environmental consulting services following a 4000-litre diesel spill in a remote mountainous area in BC, with regulatory involvement by the Provincial and Federal Governments. At the time of the spill the soil surface at the Site was covered in approximately 4m of snow… (continued).
What can we learn from subsurface investigations?
When an Area of Potential Environmental Concern (APEC) is identified as part of a Phase I Environmental Site Assessment (Phase 1 ESA), we provide recommendations for a Phase II ESA. Depending on the APEC and the estimated potential impacts we may recommend a subsurface investigation to assess the potential impacts to soil and if warranted, groundwater… (continued).
I need a Site Profile. What is it and who should complete it?
A Site Profile is a standardized form from the Ministry of Environment and Climate Change Strategies (MOECCS) that is used to screen certain commercial and industrial properties for potential contamination resulting from current or historical land use activities. A Site profile is often required to be completed for a property when applying for a development permit, rezoning, subdivision, soil removal or demolition of a property… (continued).
“Bercum Builders trusts the team at Sage Environmental to help us navigate the complexities of the environmental requirements pre-construction, during construction, and post-construction. As regulations continue to change and evolve, we rely on their expertise to guide us through to successful project completion.”
“From our initial meeting and throughout the project spanning 9 months, I have been impressed by Sage Environmental’s knowledge, practicality and demeanor. Sage Environmental has always exhibited professionalism beyond reproach and has been responsive to the need of a small company to contain the costs.”

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).
Schedule 2 uses are land uses or operations that are associated with a higher likelihood of potential impacts to soil, water and soil vapour. Common examples of Schedule 2 uses are gas stations, dry cleaners, and automotive repair. An identified Schedule 2 use does not mean that a property is contaminated. It does mean assessment is likely to be requested by the Ministry of Environment (BC ENV) prior to potential development, subdivision or change in zoning.
