On August 21st 2013, the EPA announced its approval of the proposed changes for ASTM E1527-13. With that, we’re now only one step away from the implementation of the updated industry standard. The American Society for Testing Materials (ASTM International) has been in the process of updating the industry’s Standard Practice for Phase I Environmental Site Assessments (ESAs) to reflect recent changes in the due diligence world. Until this announcement, the updated standard was awaiting review and approval by the US Environmental Protection Agency (EPA). The EPA has now announced that the 2013 version of ASTM E1527 is compliant with the All Appropriate Inquiries regulation. In other words, they have concluded that it meets all requirements and can be used as the industry’s Standard Practice for environmental due diligence. Unless the EPA receives adverse comments by September 16, the revised standard will become effective as of November 2013.  So far, one comment has been received that may or may not be considered adverse. Some of the key changes of ASTM E1527-13 include:
  • Revised definitions of the various Recognized Environmental Conditions (REC and HREC), and the addition of a new category: the Controlled Recognized Environmental Condition (CREC), which applies to sites where the contamination incident has received a risk-based closure, but could still pose ongoing or future obligations for the owner, such as special precautions during development or maintenance of an engineering control such as a vapor barrier. These definition adjustments will allow environmental professionals to provide greater clarity in disclosing the degree of risk.
  • A greater emphasis on assessing Vapor Migration Risk and a stronger imperative for conducting regulatory file reviews. These extra requirements should improve the quality of Phase I ESAs across the board, especially for those consultants who were not already meeting these criteria. These changes will also further help clients to understand and minimize exposure to environmental risks.
