Phase I Environmental Site Assessments

A Phase I ESA identifies a Recognized Environmental Condition – the presence or likely presence of hazardous substance or petroleum product, either on the target property or an adjoining property.  Phase I ESAs are required by some lenders and recommended by most as a good practice in order to know what possible issues you are purchasing.

If completed before purchasing the property, these conditions (if found) are identified as pre-existing and the potential buyer is relieved of liability for the clean-up under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA).

A typical Phase I Environmental Site Assessment takes 3-4 weeks, with much of that time dedicated to research. The result is a report of the findings and an opinion regarding the presence of Recognized Environmental Conditions and next steps.
