Environmental site assessments on PEI

Why it matters

Former garages, fuel sites, dry cleaners, machine shops, and some farm and industrial uses can leave contamination in soil or groundwater. Cleanup can be expensive and slow. It can also stop a lender from lending. Many lenders require an environmental site assessment on commercial property, and a buyer has good reason to want one regardless.

Phase I

A Phase I assessment is a review, not a dig. A qualified consultant looks at the site’s history, government records, aerial photos, and the current condition, and interviews people who know the property. It identifies areas of potential concern. It does not prove a site is clean. It tells you where to look next. In Canada, Phase I reports are commonly done to a recognized national standard. Ask your consultant which one the report follows, and who can rely on it.

Phase II

If the Phase I finds a concern, a Phase II tests for it. That usually means soil samples, groundwater wells, and lab results compared with the applicable criteria. A Phase II takes longer and costs more, and results can lead to more testing. It can change the price, the structure of the deal, or whether the deal happens at all.

PEI rules and records

The province keeps a public Contaminated Site Registry that you can search by community or parcel number. PEI’s Petroleum Hydrocarbon Remediation Regulations require environmental site assessments under them to be done by a site professional, and set out how remediation, monitoring, and closure reports work. They also deal with notifying the province about certain findings. Ask your consultant what a finding may trigger, and your lawyer what it means for the deal.

Fuel tanks on commercial sites can fall under the province’s Petroleum Storage Tanks Regulations. Ask what tanks exist, or used to exist, and whether removals were documented.

Checklist

Before the environmental condition comes off:

• Contaminated Site Registry search by PID
• Seller’s past environmental reports and closure letters
• History of the site and neighbouring sites
• Fuel tanks, past and present, and removal records
• Phase I by a qualified consultant, with reliance for you and your lender
• A plan and time for a Phase II if the Phase I recommends it
• Your lawyer’s view on who carries cleanup risk after closing

Worked example: a former service station next door

Illustrative example only. The figures are made up to show the method. They are not PEI market data or averages.

A buyer is looking at a small retail building. The Phase I notes that a property across the road was a service station decades ago, and recommends limited testing near the shared boundary. The buyer’s 21-day condition has 9 days left. The consultant says a Phase II needs about three weeks.

The options are to ask for an extension, to negotiate a price that reflects the unknown, or to walk away. Closing on a recommendation you have not followed is the riskiest choice. Lenders often will not lend until the question is answered.

Who pays for the Phase II is also negotiable. Some sellers agree to share it. Put the arrangement in writing.
