Important Considerations
The ASTM transaction screen, Phase I and Phase II Environmental Site Assessments (ESAs) differ both in intent and scope.
The ASTM transaction screen is a method of site assessment involving interviews of owners and occupants of the property and a site inspection. The transaction screen can be completed by the owner or other party attempting to assess the environmental property risk. It is important to note that completion of the transaction screen does not shield owners from certain liabilities for cleanup under federal law.
A Phase I ESA is a more in-depth inspection of a site including a review of pertinent records, a site visit, interviews with past and present owners, occupiers and operators of a property, and interviews with local government officials. Many parts of the Phase I and Phase II ESAs can only be completed by a qualified professional.
A Phase II ESA is a more in depth study undertaken when a site is deemed to pose an environmental risk. It typically involves testing the site for contaminants. A Phase II Environmental Site Assessment can either be triggered by a Phase I ESA or a Transaction Screen. The primary purpose of a Phase II ESA is to determine the level of contamination identified in either the Phase I assessment or the Transaction Screen.
Innocent Landowners: Public Law 107-118, Section 223 clarifies what action landowners must take to satisfy the "all appropriate inquiries" requirement of the defense. After May 31, 1999: ASTM "Standard Practice for Environmental Site Assessment: Phase 1 Environmental Site Assessment Process"
