Why carry out an Environmental Site Assessment (ESA) – Phase I study?
In the context of refinancing or buying a property, financial institutions require their client to provide them with an environmental phase I study.
The objective of this study is to identify the presence or not of potential or existing sources of contamination on the Site under study and the surrounding properties likely to cause an environmental impact on the underlying soils and / or receiving environments.
As part of the Environmental Site Assessment (ESA) – Phase I, a site visit is carried out, as well as historical research on the property under study and the sector in order to establish the history of the Site. In addition, searches are also made in the available environmental databases, as well as with ministerial and municipal authorities.
The methodology used for this mandate is based on recommendations given in the Canadian Standard Association document number CSA Z-768-01 which includes, among others, the following:
- A review of the aerial photographs, the soil usage plans and the fire insurance maps available for the site and its neighbouring properties (and all available maps) ;
- A request of information relative to the site from government agencies ;
- A review of the present and former uses of the site and the neighbouring sites ;
- A consultation of all contaminated sites directories such as the list of contaminated sites ;
- A review of aboveground and underground tanks registries ;
- A review of the methods applied or used to control, stock and eliminate hazardous or non hazardous waste materials and the review of the disposal and management of wastewaters ;
- An inspection of all electrical equipment that could contain PCBs and CFCs ;
- An inspection of all materials that could contain asbestos, UFFI, lead paint and FCR ;
- An inspection of equipment that contain or could contain hydraulic fluids, such as elevator shafts and loading docks ;
- A review of past studies, reports or documents provided by the client or his representative ;
- A visit of the site with resources personnel in order to identify all aspects that this site and its structures may contain, as well as a visual inspection of the neighbouring properties in order to identify elements that could represent an environmental risk to the site.
A report will be presented to you within seven (7) to ten (10) working days from the date of signing of the mandate.
