Understanding the Changes to the ASTM Phase I Environmental Site Assessment (ESA) Standard – Webinar

May 23, 2023 @ 2:00 pm - 3:00 pm

ASTM International’s environmental assessment, risk management and corrective action committee (E50) recently revised its standard practice E1527-21 for Phase I Environmental Site Assessments (ESAs). The E1527 standard was originally published in 1993 to define “good commercial and customary practice” for conducting Phase I ESAs, as well as meeting the USEPA’s All Appropriate Inquires Rule. The latest revision, published on November 15, 2021, represents over three years of work and consensus-building by a team of over 250 experienced industry professionals, including a balance of Users and Producers. This presentation highlighted key updates to the most current version of the standard.

Elizabeth led the historical research focus group of the E1527 Task Group, which proposed revisions to reflect the current standard of care for the property due diligence industry.
