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

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.
