Will the Adoption of the ASTM E1527-21 Standard Practice Result in an Increased Phase I ESA Cost?
EPA’s Final Rule approving the ASTM E-1527-21 became effective on February 13, 2023, meaning that the updated standard may now be used to satisfy the All Appropriate Inquiry (AAI). This is a critical development for property purchasers seeking to qualify for the bona fide prospective purchaser (BFPP) safe-harbor defense to property liability under Federal and some state Superfund laws. EPA’s approval of the ASTM E1527-21 Standard came by a notice of Final Rule published December 15, 2022, following an extended review process.
