Phase I Environmental Site Assessment
A Phase I Environmental Site Assessment (ESA) – 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 purpose of an Phase I ESA is to identify existing and potential site contamination and may assist in reducing uncertainty about potential liabilities and could highlight that further investigation is necessary for the site.
The Phase I ESA is a details 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.
A Phase I ESAs can help you make informed decisions about a property transactions, and can identify baseline environmental conditions of a property prior to a sale.
The process of compiling an Phase I ESA involves the review of current and past land uses (includes a site visit), record searches, personal interviews and an analysis of record searches, which includes 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.
