A Transaction Screen Assessment (TSA) is a limited environmental due diligence tool used primarily in commercial real estate transactions to identify potential environmental concerns without conducting intrusive testing. Conducted in accordance with ASTM E1528-22 standards, a TSA typically includes a site visit, visual inspection of the property and surrounding areas, a review of regulatory and historical records, and interviews with property owners or operators using a Transaction Screen Questionnaire. It is designed to provide a cost-effective, lower-scope alternative to a Phase I Environmental Site Assessment, helping lenders and buyers assess environmental risk before proceeding with a transaction.
