phase I ESA


The Phase I Environmental Site Assessment is a very common report used to identify potential or existing environmental contamination liabilities for real estate properties.  Early history of Phase I ESA’s date back to the 1970’s with studies assessing the risks of owning commercial properties potentially contaminated with toxic chemicals or disposal.  Creation of today’s Phase I ESA was largely a result of the U.S. courts passing the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA).     

In addition to providing protections under CERCLA, a Phase I ESA may identify:

  • Conditions that devalue a property

  • Indicators of Business Environmental Risk

  • Environmental conditions that present a risk to employees, customers, and/or residents

  • Issues that may result in regulatory enforcement actions

Environmental Transaction Screening Assessment

If the prospective purchaser decides they would like a less rigorous environmental assessment, as is sometimes the case, White Buffalo Environmental can provide an Environmental Transaction Screening Assessment that evaluates environmental risk, but does not include all of the steps necessary to meet the requirement for establishing CERCLA Landowner Liability Protection.
