For SBA lenders
Short answer
If undisclosed environmental contamination is discovered post-closing, the lender must immediately notify the SBA, conduct further due diligence (e.g., Phase II ESA), and work to mitigate the risk to collateral and the SBA's interest.
SOP 50 57 requires lenders to act prudently upon discovery of environmental issues. This includes informing the SBA, assessing the scope and cost of remediation, and taking commercially reasonable actions to protect the collateral and prevent further contamination or financial loss. Failure to act diligently can jeopardize the guaranty.
Six months after closing, a borrower discovers underground storage tanks leaking on the collateral property. The lender immediately contacts the SBA, orders a Phase II ESA, and explores remediation options to protect its security interest.
