The U.S. EPA has approved the American Society for Testing and Materials (ASTM) Standard E1527-13 as sufficient to satisfy All Appropriate Inquiry (AAI) for potential liability under CERCLA.
Updates and revisions have been made to definitions, terms, and sections of E1527-13. As such, users of E1527-13 should make themselves familiar with these changes and the implications that they may have.
E1527-13 will impact public and private parties as prospective purchasers, innocent landowners, or contiguous property owners who intend to claim a limitation on CERCLA liability in conjunction with the purchase of a potentially contaminated property.
A comprehensive summary of all revisions to E1527-13 is available here.
