Understanding ASTM Standards in Phase 1 ESA

What Are ASTM Standards in Phase 1 ESA?

ASTM standards, such as ASTM E1527-21, establish the scope and requirements for conducting Phase 1 Environmental Site Assessments (ESAs). These assessments are designed to identify Recognized Environmental Conditions (RECs) and evaluate potential contamination risks on a subject property before its acquisition.

The rule mandates that environmental professionals follow a standardized process, ensuring consistency in environmental due diligence. Compliance with ASTM standards aligns with federal regulations such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and helps purchasers and owners mitigate liability risks.

Why ASTM E1527-21 Matters for Phase 1 ESAs

The ASTM E1527-21 standard is the latest version of the Phase 1 ESA framework, refining the process of environmental inquiries to assess contamination risks. This standard is essential for ensuring a legally defensible due diligence process, protecting buyers and lenders from unexpected environmental liabilities, and maintaining regulatory compliance.

Key Features of ASTM E1527-21:

• Comprehensive Historical Research – Expanded scope of property history research, requiring extensive review of records.
• Updated Definitions of RECs – A clearer definition of what constitutes a Recognized Environmental Condition.
• Addressing Emerging Contaminants – Acknowledgment of contaminants like per- and polyfluoroalkyl substances (PFAS).
• Enhanced Site Reconnaissance Requirements – Detailed guidance for environmental professionals to standardize property inspections.
• Inclusion of Government Regulations – Ensures due diligence aligns with state and federal environmental laws.

The Role of Phase 1 ESAs in Environmental Due Diligence

A Phase 1 ESA serves as the first step in environmental risk assessment, ensuring that real estate transactions are conducted with full knowledge of potential contamination risks. The information obtained from these assessments helps parties involved in real estate transactions make informed decisions, avoid legal issues, and comply with environmental requirements.
