Frequently Asked Questions Regarding Phase I Environmental Assessments:

What is a Phase I Environmental Site Assessment (ESA)?

A Phase I ESA is an assessment of a parcel of commercial real estate to evaluate for visible evidence of contamination by hazardous substances or petroleum products. A typical Phase One Report will allow a buyer or lender to make an informed decision as to the potential environmental risk associated with the purchase of the property. American Society for Testing and Materials (ASTM) sets the standard for what constitutes an environmental risk or “recognized environmental condition” (REC). A REC is defined by the ASTM standard 1527 as: “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.”

What is the purpose of a Phase I ESA?

The purpose of a Phase I ESA is to gather sufficient information to develop an independent professional opinion about the environmental condition of a property and to identify actual or potential environmental contamination which may impact a property’s value. Completion of a Phase One Report will also allow the user to satisfy one of the requirements to qualify for the landowner liability protection (innocent landowner defense) from CERCLA liability.

Why is a Phase I ESA needed?

Potential buyers will complete a Phase I Environmental report to assure they are not buying a property that has an unacceptable risk of environmental liability. Most lenders will require a Phase I Report to protect their interest in a commercial property.

What type of properties do not generally require a Phase I ESA

A Phase I ESA is generally completed for commercial properties. Residential properties generally will not need a Phase One Site Assessment, unless there are special conditions, such as an underground storage tank or a known spill on the property. Residential properties may also need a Phase One if they are adjacent to a property with a known or suspected environmental condition.

What is in a Phase I ESA Report?

A Phase I ESA report contains the following:

  • Results of Inquiry by an Environmental Professional
  • Interviews with Past and Present Owners, Operators, and Occupants
  • Reviews of Historical Sources of Information
  • Searches for Recorded Environmental Cleanup Liens
  • Reviews of Federal, State, Tribal, and Local Government Records
  • Visual Inspections of the Facility and of Adjoining Properties
  • Commonly known or reasonably ascertainable information about the property.
  • The degree of obviousness of the presence or likely presence of contamination at the property, and the ability to detect the contamination by appropriate investigation.
