Phase 1 Environmental Site Assessments in Cornwall
Phase 1 ESAs for Cornwall properties use whichever framework applies — CSA Z768-01 or O. Reg. 153/04.
Phase 1 Environmental Site Assessments in Cornwall
Financing and transaction work generally uses CSA Z768-01; O. Reg. 153/04 is required where a Record of Site Condition, rezoning or permit is involved.
We carry out Phase 1 Environmental Site Assessments in Cornwall using records review, a site visit and interviews to flag potential contamination, with no sampling involved at this stage. We attend from our Ottawa office, roughly 88 km away — close enough that a site visit is never the bottleneck.
The Phase 1 ESA page covers the full process and what the report contains.
A Phase 2 ESA follows when a concern is identified — see our Phase 2 ESA page for Cornwall.
