What to Expect from an ASTM Phase 1 Environmental Site Assessment

Introduction

In the world of commercial real estate, environmental due diligence is essential to minimize risks associated with contamination and ensure regulatory compliance. The ASTM Phase 1 Environmental Site Assessment (ESA) is the gold standard for this process, providing a detailed analysis of potential environmental liabilities that could impact a property’s value or future use.


This guide will walk you through what a Phase 1 ESA entails, why it’s essential for CRE investors, lenders, and developers, and how KOW Building Consultants helps you navigate the process with confidence.


What is an ASTM Phase 1 Environmental Site Assessment?

The ASTM Phase 1 ESA (standardized as ASTM E1527) is a preliminary assessment conducted to identify potential environmental concerns or contamination risks on a property. It is designed to evaluate whether past or present activities on or near the property may have introduced hazardous substances or pollutants, which could lead to costly cleanups or legal liabilities.


The assessment typically covers four major components:

  1. Site Visit: A visual inspection of the property and its surroundings to identify any signs of contamination.

  2. Historical Records Review: Research into the property’s historical uses and ownership records to uncover past activities that may have posed environmental risks.

  3. Environmental Database Search: Reviewing government and environmental databases for documented incidents or contamination reports related to the property.

  4. Interviews: Discussions with current owners, tenants, and local government officials to gather additional context on the property’s history and any potential environmental concerns.



Why is a Phase 1 ESA Important for CRE Investments?

A Phase 1 ESA is often required by lenders, investors, and regulatory bodies because it helps:

  • Identify Potential Contamination: Understanding any existing or potential contamination early on prevents costly surprises post-acquisition.

  • Minimize Legal and Financial Risks: Completing an ESA helps establish the “All Appropriate Inquiries” (AAI) standard required by the EPA to qualify for certain liability protections under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

  • Facilitate Informed Decision-Making: Knowing the environmental conditions of a property can guide investment decisions, from adjusting the purchase price to budgeting for potential remediation costs.

  • Satisfy Lender Requirements: Lenders often mandate a Phase 1 ESA to mitigate their financial exposure and ensure compliance with environmental standards.


What Does the Phase 1 ESA Process Look Like?

The Phase 1 ESA process typically involves the following steps:

  1. Preliminary Site Visit and Property Inspection

    • Environmental professionals conduct a thorough inspection, looking for visible signs of contamination, such as petroleum stains, storage tanks, or unusual odors.

  2. Historical Research

    • This phase includes analyzing historical aerial photos, city directories, topographic maps, and Sanborn fire insurance maps to trace the property’s previous uses.

  3. Review of Environmental Databases

    • Specialized databases are used to check for records of environmental incidents, contamination reports, or hazardous material storage near the property, ensuring all known environmental records are covered.

  4. Interviews with Stakeholders

    • Interviews are conducted with people familiar with the property, including owners, tenants, and local officials, to gain further insights into past or present environmental risks.

  5. Report Compilation

    • Finally, all findings are compiled into a comprehensive report, detailing any Recognized Environmental Conditions (RECs) that may require further investigation or remediation.


What are Recognized Environmental Conditions (RECs)?

One of the key outcomes of a Phase 1 ESA is identifying any Recognized Environmental Conditions (RECs). These are environmental issues that could present a risk of contamination and may need further assessment (often through a Phase 2 ESA). Examples of RECs include:

  • Evidence of underground storage tanks

  • Historical use of hazardous materials

  • Documented contamination incidents


If RECs are found, further analysis (typically a Phase 2 ESA) may be required to determine the extent of contamination and identify appropriate remediation actions.


When Should a Phase 1 ESA be Conducted?

A Phase 1 ESA is typically conducted in the following scenarios:

  • Before Property Acquisition: Ensures that investors have a complete understanding of any environmental liabilities before closing.

  • Prior to Financing or Refinancing: Lenders often require a Phase 1 ESA as part of the underwriting process.

  • During Redevelopment or Change in Property Use: If a property’s use is changing, an ESA helps identify potential environmental impacts associated with the new activities.

  • For Compliance with Regulatory Requirements: Certain government projects or transactions require an ESA to comply with federal, state, or local regulations.
