What is a Phase 1 ESA and the New AAI Rule?
The purpose of an Environmental Site Assessment (ESA) Process is to identify recognized environmental conditions. These are the presence or likely presence of any hazardous substances or petroleum products on "The Property" under conditions that indicate an existing release, a past release or a material threat of a release into structures, ground, groundwater or surface water of "The Property" even under conditions in compliance with laws.
The Environmental Protection Agency (EPA) has established federal standards and practices for conducting all appropriate inquiries as required under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The final rule establishes specific regulatory requirements and standards for conducting all appropriate inquiries into the previous ownership and uses of a property for the purposes of meeting the all appropriate inquiries provisions necessary to qualify for certain landowner liability protections under CERCLA.
