ASTM E1527-05 Standard – Phase I Environmental Site Assessments
The ASTM E1527-05 Standard is the industry standard used for Phase I Environmental Site Assessments. Fully named “ASTM E1527-05 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process,” the Standard outlines the purpose and use of the Phase I ESA as well as the scope of work to be conducted, including: records review (historical and governmental records); site reconnaissance (inspection of the property and adjacent sites); interviews (with owners and occupants and local government officials); evaluation and report preparation.
The ASTM E1527-05 Standard was created by the American Society for Testing and Materials (now simply ASTM International), and is designed to meet the EPA’s requirement for All Appropriate Inquiry for environmental due diligence. The E1527 Standard for Phase I ESAs has gone through several iterations, the latest being finalized in 2005. The standard is reviewed and revised by the ASTM Committee E50 on Environmental Risk Assessment, Risk Management and Corrective Action.
