Phase I ESA

The Phase I Environmental Site Assessment (ESA) is an integral and necessary assessment service for the acquisition of bank financing, undertaking development, or collecting due diligence data prior to real estate acquisition and divestiture. Envirotech Engineering has extensive experience in conducting Phase I Environmental Site Assessments and is on the approved vendor list for many of the largest financial institutions in Canada. 

The standard scope of work for our typical Phase I ESAs includes:

  • Record Reviews to establish former owners, tenants or businesses that occupied the site as well as current and historical land use activities on the Property. This information allows us to understand what kinds of operations have occurred at the site in the past and to identify potential areas of contamination or environmental liability.
  • Site Inspections to evaluate site issues identified during the document review process and to identify and potential contaminant indicators and any other common indicators of environmental impairment.
  • Interviews to corroborate or augment information and data collected during the document review and site inspection process. Individuals with knowledge of the site are interviewed to determine if there are any current and historical land use practices at the site which may have resulting in contamination or environmental liability .

Phase I ESA reports are always compiled at the completion of each assessment detailing the findings, conclusion and recommendations of the project. Depending on the findings of our assessment, typical recommendations can include hazardous building assessments, Phase II ESAs or no action at all.
Our Phase I ESAs can be completed to meet the requirements of several standards:

  • Canadian Standards Association (CSA) Z768-01 (R2012) Phase I Environmental Site Assessment;
  • The City of Calgary Terms of Reference for a Phase I Environmental Site Assessment (2005);
  • American Standard Testing Method (ASTM) E1527-05 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process;
  • Oil and Gas Standards.
