Buying or selling property that is known to have some contamination can be a challenge. Under Wisconsin’s Spill Law, responsibility for investigating the extent of contamination and restoring the environment falls not just on those who caused the contamination, but also the current property owner, regardless of whether they had anything to do with it. For this reason, buyers generally look for a discounted price or indemnification from the seller when they know there is a contamination issue.
What if you don’t know for sure if there is contamination?
When it comes to property with a history of commercial or industrial use, prospective buyers (or their lenders), routinely hire environmental consultants to help them evaluate the potential for contamination to exist. These investigations start with a Phase I Environmental Site Assessment (ESA), which typically consists of a site visit, a review of historical records and environmental data bases, and interviews with owners to identify what are referred to as recognized environmental conditions (RECs). However, no testing of soil or groundwater is completed.
If the Phase I indicates there is reason to believe the property is or could be contaminated, the consultant will generally recommend a Phase II ESA, which would involve environmental sampling to confirm or rule out the suspected contamination. From the buyer’s perspective, this information allows them to evaluate legal, business and environmental risks based on known data.
Do you have to allow additional testing?
But what about the seller? Should a seller allow the buyer to conduct a phase II ESA or not? Or should a seller get ahead of the issue and do its own phase II to know just what the issues may be? These are difficult decisions because once an owner knows about the presence of contamination, they are legally obligated to report it to the DNR.
This notification has consequences. If the contamination is limited and no remediation needed, the DNR may determine no further action is required. But, if the DNR determines that further investigation is needed, it will issue what is referred to as responsible party letter, informing the owner of their legal obligation to engage a qualified environmental consultant to determine the full nature and extent of the contamination in soil and groundwater. This could lead to investigating whether contamination has gone beyond the property line and even whether contaminated vapors have migrated to indoor air at the property and adjacent properties.
