What is a Phase I ESA ? 

Did your bank tell you that you need a Phase I ESA, but aren’t sure where to start?

Essel is here to help. 

What is a Phase I ESA? 

A Phase I Environmental Site Assessment is an environmental report that documents the history of a property. 

Engineers conduct Phase I ESAs on all types of property, including residential, commercial, industrial, or agricultural properties. They’re even conducted on undeveloped lands. 

The report, conducted by an environmental firm, examines the history of the site down to its earliest available records. In a Phase I ESA, the firm conducting the examination is looking for any “high-risk uses” of the property or adjacent properties that might contribute to a REC on the property in question. An REC is an acronym for a “recognized environmental condition.” 

Some common “high-risk uses” of a property include: 
  • It was previously used as a gas station, service station, or repair shop.
  • Previously, the property was used as a junkyard, metal shop, or automobile salvage.
  • The property used to be a dry cleaner’s for any number of years. 

The possibility of a REC on the property could warrant further testing of soil and groundwater for contamination. Engineers often refer to as a Phase II Environmental Site Assessment (Phase II ESA) or a soil vapor test. 

There are many different types of RECs that vary in levels of complexity and importance. The most common RECs are related to abandoned oil wells, leaky underground storage tanks (USTs), residual dry cleaning chemicals, or improperly disposed of or stored chemical waste. 

Please note that no sampling is conducted on the property during a Phase I ESA. A Phase I ESA is a visual inspection of the property where engineers comb through records, conduct a site visit, and talk to former property owners, the owners of adjacent properties, and relevant others. As previously mentioned, a Phase I ESA determines if one should perform further testing on the property.
