On October 6, 2014, EPA finalized an amendment to the “All Appropriate Inquiries” (AAI) rule to remove the reference to ASTM E-1527-05. 79 Fed. Reg. 60087. This means that ASTM E-1527-05 is no longer adequate to establish landowner and lender liability protections under CERLA. Buyers, sellers, and lenders take note: you will now need to ensure that your AAI is conducted under the newer 2013 ASTM standard.
“All Appropriate Inquiries,” or AAI, is the process of evaluating a property’s environmental conditions and assessing the likelihood of any contamination. Buyers, Sellers and Lenders involved in the transfer of real estate, including real estate transferred as part of a corporate merger, acquisition or asset sale, know that ASTM E-1527 is the typical starting point for conducing AAI and thus obtaining landowner and lender liability protections under the environmental statute CERCLA. In 2013, the 2005 ASTM standard was revised (see our article, SOMETHING NEW IS IN THE AIR: Important Changes to ASTM E 1527 “Phase I” Environmental Due Diligence, to read more about the 2013 revisions). EPA’s policy at the time was that both ASTM E1527-05 and E1527-13 were consistent with the AAI rule at 40 CFR Part 312. Now, however, EPA has amended the AAI rule to remove the reference to ASTM E-1527-05, thus rendering the 2005 standard inadequate for establishing CERCLA landowner and lender liability protections.
The amendment comes after EPA received many adverse comments in response to its decision to allow both ASTM E1527-05 and E1527-13. Commenters stated that using two standards could create confusion, especially since even ASTM no longer recognizes 2005 as meeting its standards for good customary business practice. EPA ultimately agreed, and is now requiring the 2013 standard to establish AAI. Thus, if you are commissioning a Phase 1 audit report to establish AAI, you will need to make sure the environmental consultant performing the Phase 1 relies upon ASTM E1527-13.
