Commercial Phase I Environmental Site Assessments – Alberta

Basin Environmental Ltd. (Basin) provides Phase I Environmental Site Assessment (ESA) services to oil and gas, industrial and commercial industries.  Basin’s personnel have conducted Phase I ESA’s throughout Alberta including Edmonton, Calgary, Red Deer, Fort McMurray, Peace River, Edson, Valleyview, Fox Creek, Grande Prairie, Cold Lake, Lethbridge, Brooks, Medicine Hat and Fort McLeod. Our Edmonton and Calgary offices provide easy access to projects throughout northern and Southern Alberta. 

Phase I Environmental Site Assessment’s are a non-intrusive site investigation designed to assess the environmental condition of a site and/or building(s).  It assesses the risk of potential environmental liability at a property associated with current or historical activities at the site and neighboring properties.  It includes a historical review, site visit and personal interviews.

The typical scope of our Alberta Phase I Environmental Site Assessments includes the following:

  • A review of current title as well as historical title search.
  • A review of current/historical aerial photographs.
  • A search of the Environmental Law Centre.  
  • A search of the Petroleum Tank Management Association of Alberta
  • Completion of a site inspection to identify potential concerns on the Alberta property.
  • Interview with the current owner of the property.
  • Preparation of a report documenting the findings, conclusions, and recommendations arising from the study.

The final report follows the Canadian Standards Association (CSA) document “Z768-01 Phase I Environmental Site Assessment”, dated November 2001 in addition to meeting Alberta Environment requirements.  Environmental Site Assessments assist in reducing uncertainty about potential environmental liabilities and in making informed decisions about property transactions.  Our client base includes energy companies, realtors, property developers, lending institutions and business owners. 

A Phase I ESA does not include the collection or laboratory analyses of samples of soil, groundwater, or other materials; these activities are associated with Phase II Environmental Site Assessments.
