Environmental Site Assessments are performed prior to property transfer or the closing of industrial and commercial real-estate transactions to determine if recognized environmental conditions exist on a subject property.

Phase I Environmental Site Assessments (ESA)
A Phase I Environmental Site Assessment (ESA) is the gold standard for evaluating the environmental liability associated with a real estate asset.  A Phase I ESA is used to identify actual and potential environmental concerns and contamination at a Site which may impact the property value or affect claim to an “innocent land owner” exemption following acquisition.

What is a Phase I Environmental Site Assessment?
A Phase I Phase I Environmental Site Assessment (ESA) is the initial step in environmental due diligence, conducted to evaluate and assess the environmental conditions of a property. It provides valuable insights into the historical use of the site and identifies any existing or potential environmental liabilities. It aims to identify recognized environmental conditions (RECs) and potential sources of contamination that may impact the property’s value or pose risks to human health and the environment.

American Environmental Phase I ESA reports are prepared by experienced Geologist and Environmental Professionals in accordance with the most recent American Society for Testing and Materials (ASTM) Standard E 1527, Standard Practice for Environmental Site Assessment: Phase I Environmental Site Assessment Process. This practice is the industry standard for conducting ESAs and is the basis for justifying due diligence satisfies the Comprehensive Environmental Response Compensation and Liability Act’s (CERCLA) requirements for Landowner Liability Protections.

The Key Components of American Environmental Phase I ESA:
A thorough review of historical records, site inspections, and interviews to identify recognized environmental conditions (RECs) and potential sources of contamination.

  1. Historical Research: Our experienced team conducts extensive research to uncover the property’s historical uses, past activities, ownership, and potential environmental concerns or sources of contamination. American Environmental review historical records, maps, aerial photographs, historical land use records, and regulatory databases to identify any past activities that may have led to contamination.
  2. Site Inspection: A physical inspection of the property is conducted to assess current conditions and identify potential environmental concerns. Our experienced environmental team examines buildings, structures, storage tanks, and surrounding areas for evidence of spills, leaks, or environmental hazards.
  3. Interviews and Documentation: Interviews with current and past property owners, occupants, and local officials are conducted to gather additional information about the property’s history and potential environmental issues. We also review relevant documents, such as permits, environmental reports, and regulatory filings.
  4. Expert Analysis and Phase I ESA Report: Based on the findings of the investigation, a detailed Phase I ESA report is prepared, outlining the environmental conditions of the property, identifies any RECs or potential sources of contamination, and provides recommendations for further assessment or mitigation, if necessary. Our reports are clear, concise, and compliant with industry standards and regulatory requirements.

The Importance of Phase I ESAs and Benefits of Conducting a Phase I ESAs:

  • Risk Management: Conducting a Phase I ESA helps property owners and prospective buyers identify potential environmental risks early in the due diligence process. This allows for informed decision-making and risk management strategies to minimize liabilities and protect investments.
  • Regulatory Compliance: Phase I ESAs are often required by lenders, insurers, and regulatory agencies as part of property transactions and development projects. Compliance with ASTM standards ensures that the assessment meets industry best practices and regulatory requirements.
  • Liability Protection: By conducting due diligence through a Phase I ESA, property owners may qualify for liability protections under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) “innocent landowner defense” or “bona fide prospective purchaser” provisions.
