JD Supra Washington, DC

Environmental Protection Agency, on March 14, 2022, 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. Despite EPA’s request for comment on the rule, the agency indicated that it does not anticipate adverse pushback. The rule is expected to go into effect on May 13, 2022, unless EPA receives significant negative comments.
