New Environmental Assessment Standard for Brownfields

In November, 2013 the American Society for Testing Material (“ASTM”) adopted ASTM E1527-13 for the assessment of Brownfield properties. An ASTM Task Force has determined that more than 60% of environmental professionals are using the standard for all their Phase I assessments, and the U.S. EPA has adopted the standard for its “All Appropriate Inquiry Rule.” The new standard is more restrictive than the ASTM E1527-05 standard and is arguably more protective of the potential purchaser. Most notably, the new standard requires the environmental professional to assess the site for potential vapor intrusion – a consideration that historically has been outside of the scope of a Phase I. It should be noted that, while the EPA and ASTM have published and adopted the new standard, the new standard specifically states that a potential purchaser may satisfy the all appropriate inquiry rule by following either the ‘05 or ’13 rule.
