Why Your Lender Wants a Phase I: CERCLA Liability in Plain English
Phase I, Piece by Piece is a weekly series that walks through the Phase I Environmental Site Assessment one part at a time. This is week 2.
Last week we covered what a Phase I is. This week is about why it exists: a 1980 federal law that can make you responsible for contamination you had nothing to do with.
The law: CERCLA
The Comprehensive Environmental Response, Compensation, and Liability Act, better known as Superfund, lets EPA make "potentially responsible parties" pay to clean up contaminated sites. That list includes the current owner of the property. Liability is strict (fault doesn't matter), and it can be joint and several, meaning one party can be on the hook for the whole cleanup.
For a buyer, that's the scary part. Buy a property where a plating shop dumped solvents in 1975, and you can become a responsible party the day you close.
The fix: three landowner protections
Congress built three protections for buyers who investigate before they buy. The innocent landowner defense dates to 1986; the 2002 Brownfields Amendments added the other two:
Bona fide prospective purchaser (BFPP). Protects a buyer even if they know about contamination, as long as they did All Appropriate Inquiries before buying and meet ongoing obligations.
Innocent landowner. Protects a buyer who did All Appropriate Inquiries and had no reason to know about contamination.
Contiguous property owner. Protects an owner whose property was contaminated by migration from a neighboring site.
All three require All Appropriate Inquiries before acquisition. A Phase I done to ASTM E1527-21 is how most buyers meet that requirement.
The catch: ongoing obligations
The protections aren't a one-time pass. After you buy, you have to take reasonable steps to stop or limit any release, cooperate with regulators, comply with any land use restrictions, and provide required notices. A Phase I that identifies a problem helps you know what those steps are.
Why lenders care
A lender's collateral is only worth something if the property isn't a liability. A contaminated property can lose much of its value, and a borrower facing a cleanup bill is more likely to default. A Phase I tells the lender what they're lending against.
A note on petroleum
CERCLA generally excludes petroleum. So why does every Phase I look so hard for gas stations and fuel tanks? Because state laws, including Missouri's tank rules and cleanup programs, cover petroleum releases, and lenders care about value regardless of which law applies. A leaking tank is still a problem for your deal, and it's the reason tank closures get so much attention during due diligence.
The bottom line
A Phase I is the price of admission to CERCLA's landowner protections and the first thing your lender wants to see. Talk to your environmental attorney about how the protections apply to your deal, and see how our Phase I ESAs work or request a quote.
