FAQ · Sioux City

When is a Phase I ESA required?

Lenders typically require a Phase I ESA on commercial property transactions to establish the innocent-landowner defense under CERCLA. It is a records-and-reconnaissance study — no sampling is performed.

What triggers a Phase II?

A Phase II is recommended when the Phase I identifies recognized environmental conditions, such as historical industrial use, nearby releases, or suspect storage tanks.
