EPA Publishes Final Rule to Eliminate ASTM E-1527 Standard Uncertainty

At the end of December 2013, the updated ASTM International Standard for Phase I Environmental Site Assessments, ASTM E1527-13, was incorporated by the EPA into its All Appropriate Inquiries (“AAI”) rule.  Complying with EPA’s AAI rule is critical to one’s ability to assert the innocent landowner defense and/or to establish oneself as bonafide prospective purchaser for purposes of CERCLA liability as provided for in the Brownfields Amendments.

When this new E1527-13 standard was adopted by the EPA last year, EPA elected not to remove the reference to the prior ASTM E1527-05 standard from its AAI rule, which left some uncertainty as to which standard would qualify for compliance with the provisions of the AAI rule.  Because the 2013 standard required evaluation of vapor migration and contained updated definitions of Recognized Environmental Conditions, it was considered the more conservative approach despite its generally higher cost*.

However, in October 2014, EPA eliminated the uncertainty surrounding which standard to follow by publishing a final rule that eliminates the 2005 standard.  This final rule will take effect October 16, 2015.  Parties undertaking environmental due diligence should confirm that any Phase I, Phase I update or reliance letter satisfies the new E1527-13 standard if they desire to seek the protections afforded by the Brownfields Amendments.
