What is a Phase I?


A Phase I Environmental Site Assessment (ESA) is a non-intrusive investigation into current and historical site uses.  It will consist of current and historical records reviews on federal, state, and local levels, a site visit by an Environmental Professional, interviews with past occupants, property owners and others, as well as a review of various other sources of historical and current site information.  The culmination of the findings is rolled into a recommendation by the Environmental Professional as to whether or not a Recognized Environmental Condition (REC) exists at the site and whether or not the said REC requires further investigation and/or corrective action.  A Phase I ESA should follow to the extent possible and practical the standards set forth in ASTM E 1527-13.

In 1998 the necessity of performing a Phase I ESA was underscored by congressional action in passing the Superfund Cleanup Acceleration Act of 1998. This act requires purchasers of commercial property to perform a Phase I study meeting the specific standard of ASTM E 1527: Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.

The most recent standard is “Standards and Practices for All Appropriate Inquiries” 40 Code of Federal Regulations, Section 312 which drew heavily from ASTM E 1527-05 which has become known as ‘All Appropriate Inquiry’ (AAI).

Residential property purchasers need only conduct a site inspection and chain of title survey.
