The American Society of Testing and Materials (ASTM) is revising the Phase I Environmental Site Assessment Standard (ASTM E1527). This is the standard which guides the scope of Phase I Environmental Site Assessments (commonly called a 21E report in Massachusetts). The Phase I standard defines Recognized Environmental Condition. Determining whether a Recognized Environmental Condition is present at a property is the objective of a Phase I.
Proposed changes to the Phase I standard include:
- Revisions to the definition of Recognized Environmental Condition and Historic Recognized Environmental Condition.
- Addition of a new term – Controlled Recognized Environmental Condition.
- Clarification that vapor migration is included in the Phase I ESA standard (with reference to ASTM E2600-10; Standard Guide for Vapor Encroachment Screening).
- A new subsection specifically for regulatory file reviews.
- Revisions to the User Responsibilities section, particularly with respect to surrounding environmental lien search requirements.
The revised standard will be called ASTM E1527-13 and will likely be published in spring 2013.
