ASTM/AAI-Compliant Phase I Environmental Site Assessments (ESAs)

A Phase I Environmental Site Assessment (ESA) is a vital component of environmental due diligence for commercial real estate transactions. This assessment investigates whether a property has any environmental concerns  due to historical or current uses, especially those involving operating in certain industries that deal with hazardous materials or  substances.

Our experienced environmental professionals conduct thorough site evaluations in accordance with the most current ASTM E1527 standards and the EPA’s All Appropriate Inquiries (AAI) rule. By identifying Recognized Environmental Conditions (RECs), we help you make informed decisions and limit potential liability under CERCLA regulations.

    Understand Your Site

    A Phase I ESA doesn’t just evaluate property, but it also protects your financial future. If RECs are discovered, we’ll guide you through the next step, whether that’s further investigation with a Phase II ESA or alternative risk management options.

What to Expect From a Phase I ESA

Our comprehensive Phase I ESA process includes:

  • Records Review – Examining historical land use through aerial imagery, topographic maps, city directories, and federal/state environmental databases.
  • Site Reconnaissance – A physical inspection of the property and surrounding areas to identify visible signs of potential contamination.
  • Interviews – Conversations with current and past owners, occupants, operators, and local regulators to gather site-specific environmental information.
  • Professional Report – A detailed report summarizing findings, identifying any RECs, and recommending next steps (such as a Phase II ESA, if needed).

Why Order a Phase I ESA?

A properly conducted Phase I ESA offers:

  • Legal Protection – Helps buyers, lenders, and lessees qualify for the “Innocent Landowner Defense” under CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act) by showing they conducted all appropriate inquiry prior to purchase or lease, potentially reducing liability for preexisting environmental contamination.
  • Risk Mitigation – Protects your investment by identifying potential environmental liabilities before closing.
  • Regulatory Compliance – Meets federal and state requirements and often satisfies lender or SBA environmental due diligence obligations.
  • Decision-Making Clarity – Understand the site’s condition before purchase, development, or refinancing.
