For SBA lenders
Short answer
A Phase II Environmental Site Assessment (ESA) is required when a Phase I ESA identifies Recognized Environmental Conditions (RECs) that suggest potential contamination impacting the collateral's value or the borrower's liability.
If a Phase I ESA, which is a non-invasive investigation, reveals RECs (e.g., historical spills, underground storage tanks, adjacent contaminated properties), the lender must evaluate the risk. If the RECs indicate a high probability of actual contamination that could materially affect the property's value or create cleanup liability for the borrower/lender, a more intrusive Phase II ESA (involving sampling and testing) is then required to determine the nature and extent of the contamination.
A Phase I ESA on a property collateralizing a 7(a) loan finds evidence of a former dry cleaner operation with unknown waste disposal practices. This REC triggers the need for a Phase II ESA to sample soil and groundwater for contaminants associated with dry cleaning chemicals.
