What is a de minimis condition?
A de minimis condition is a minor issue, such as a small oil stain on pavement, that generally poses no threat to health or the environment and wouldn't be the subject of enforcement if regulators saw it.
In more detail
Phase I reports note de minimis conditions to show they were seen and judged minor. They are not RECs.
What it means when you buy
Usually nothing to act on, beyond cleanup as routine maintenance.
How the pre-screen handles it
The pre-screen does not include a site visit, so it doesn't see surface stains. It focuses on records and imagery that point to bigger issues.
