New ASTM Standard for Phase I Environmental Site Assessments
The EPA has issued both a final rule incorporating revised ASTM International standard practices, ASTM International’s E1527–21 ‘‘Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,’’ and a proposed rule soliciting comment on this action. The final rule incorporates the new ASTM standard as one of three different standards upon which prospective purchasers of real property may rely to satisfy CERCLA’s All Appropriate Inquiries (AAI) Rule. The rule is expected to go into effect on May 13, 2022, unless EPA receives significant negative comments.
Changes to the Phase I Environmental ASTM Standard
The updated ASTM standard should help to improve of clarity of its requirements, promote a more consistent practice throughout the industry, and reduce inconsistencies from firm to firm in their findings. The key changes include:
- Important terms including Recognized Environmental Conditions (REC), Controlled REC and Historical REC were redefined in an effort to promote a more logical process of identification, and to provide additional detail of established engineering and institutional controls, when applicable.
- The requirements for historical research were bolstered to require a minimum of four standard historical resources to be consulted; previously the Environmental Professional was give more latitude to consult only as many resources as needed to satisfy the standard.
- Compliance with Phase I ESA report “shelf-life” or viability period of 180 days was clarified to be applicable to five main AAI components – interviews, visual inspection, government records review, Environmental Professional’s declaration, and search for environmental cleanup liens. The dates of completion for each must now be reported in Phase I reports.
- “Emerging contaminants” (example: PFAS compounds) are now referenced as a Non-ASTM scope topic that may be addressed in a Phase I ESA report; although, as with other Non-ASTM topics, it is not necessary to comply with AAI requirements.
