Policy Update: Phase I ESA Standard

For 25 years, The Reynolds Group has performed Phase I Environmental Site Assessments (ESA’s) as due diligence for real property portfolio acquisitions and individual real estate transactions. ASTM International, formerly known as the American Society of Testing and Materials (ASTM), recently updated and released the new standard for Phase I Environmental Site Assessments, effective in November 2013. ASTM’s previous standards set the tone for professional practice and norms for conducting such work in the industry.

The new ASTM E1527-013 (the New ASTM Phase I Standard) introduces three more refined additions that include:

  • RECs, HRECS & CRECs definitions:
    • RECs (Recognized Environmental Conditions) – clarification of definition by removing the terms “into ground, groundwater and surface water.”
    • HRECs (Historical Recognized Environmental Conditions) – revision of definition by clarifying if there is a past release of a REC at the time of the conducted Phase I ESA.
    • CRECs (Controlled Recognized Environmental Conditions) – a new category intended to apply risk based descriptions about closures of contaminated sites where no further assessment and/or remediation is required by a regulatory agency, but residual contamination remains.
  • Vapor Mitigation – consideration of potential subsurface vapor mitigation into occupied areas.
  • Regulatory Agency File Reviews – ASTM E1527-013 requires consultants to conduct more thorough file reviews or explain why they are not performed.

These three key updates further refine the old ASTM E1527-05 standard. The additional file review requirement may add some time and expense to the work.

The Reynolds Group is conforming its practice to the new standard and will perform its Phase I ESA’s based on ASTM E1527-013. You can contact The Reynolds Group at (714) 730-5397 or email [email protected] for a quote.
