The 2013 ASTM Standards for Phase 1 Environmental Site Assessments (ESA) are sunsetting and are currently under revision by the ASTM Committee.

Proposed Changes to ASTM Standards for the Phase 1 Environmental Site Assessment

The American Society for Testing and Material (ASTM) requires a revision every eight years that fosters a renewal process to allow for the continuation of improvement and refining of the standard addressing the ever-changing world of environmental concerns. While the below changes have not yet finalized, it offers a glimpse of what is pending.

Notable proposed ASTM Standards changes for the Phase 1 ESA include:

• REC, CREC, and HREC definitions and clarification language
• Good customary and commercial practices
• 3^rd party provided AUL and land title searches
• Records review and tie-in to physical setting
• Site visit requirements and adjoining property requirements, based on recent litigation
• Clarification of what type of Environmental Consultants can conduct assessments
• Interviews (i.e., updating in writing by first class mail)
• More robust and detailed report requirements
• Emerging contaminants (per and polyfluoroalkyl substances (PFAS)) – man-made chemicals persistent in the environment and body
• Clarity to the definition of a Recognized Environmental Condition (REC)
• Proposed definition of “likely” within the definition of REC
