Environmental Site Assessement (ESA) Phase I

What is an ESA Phase I, why is it needed?

Environmental Site Assessment (ESA) Phase I – also referred to a Stage 1 Preliminary Site Investigation (PSI) – is typically required as a due diligence measure in support of a real estate or financing agreement for a property. The ESA is a detail orientated report that analyses the potential for actual or potential contamination of a site or property, and the potential environmental liabilities associated with the identified contamination if present.

The process of compiling an ESA involves the review of current and past land uses (includes a site visit), record searches, personal interviews and an analysis of the results of record searches including the Ministry of Environment’s Site Registry for contaminated sites. All gathered information is compiled and used to assess the potential of actual or potential contamination on a site, and if found the impact of the identified contamination.

Origo Environmental provides ESA Phase I reports that:

  • Are completed in accordance with the Environmental Management Act;
  • Fulfills Canada Mortgage and Housing Corporation CMHC guidelines and requirements;
  • Complies with the Canadian Standard Association (CSA) Standard Z768-01 – Phase I Environmental Site Assessment (R2016; and,
  • Fulfills the requirements of the BC Ministry of Environment (MOE).

We use drones to assess what out sites look like now. This is useful to assess current conditions and any remediation work required.

Why is an ESA needed?

  • To meet requirements of a development or re-development;
  • Provides real estate due diligence for a buyer;
  • Assists a vendor in expediting a sale of a property;
  • Property insurance renewals;
  • Financing and re-financing a property;
  • Commencing a lease period to establish the baseline condition of a property;
  • Lease termination to assess if contamination has become present/increased during the lease period;
  • Assessing a “brownfield property” that may have been vacant or under-utilized and where past industrial or commercial activities may have resulted in contamination; and,
  • A due diligence assessment to provide compliance with a corporate stewardship measure or policy.
