Updated Standards for Phase I Environmental Assessment

On February 27, 2023 by Schnader in Publications

Megan Harmon published an alert, titled, “Updated Standards for Phase I Environmental Assessment.”

On December 15, 2022, the United States Environmental Protection Agency (“EPA”) finally recognized ASTM Standard E1527-21 as satisfying the All Appropriate Inquiry (“AAI”) Rule (40 CFR Part 312), the standard which is used to evaluate the environmental condition of commercial property. The EPA issued proposed rules in early 2022 and then withdrew them later in 2022. This ASTM standard updates ASTM E1527-013 adopted in 2013. This new version, as well as the old ASTM E1527-13 standard, are intended to satisfy the requirements of AAI. They are and will become the standard for environmental assessments or what are called a Phase I.
