What Is a Phase 1 Environmental Site Assessment?
A Phase 1 Environmental Site Assessment (Phase 1 ESA) is a due-diligence investigation of a property's environmental history. It is the first step in identifying potential or existing environmental contamination liabilities. Conducted in accordance with ASTM Standard E1527-21 and the EPA's All Appropriate Inquiries (AAI) rule under 40 CFR §312, a Phase 1 ESA is required by most lenders, investors, and commercial real estate buyers before closing a transaction.
Who Needs a Phase 1 ESA?
Commercial real estate buyers and sellers, banks and SBA loan applicants, property investors and developers, government agencies, and attorneys handling real estate transactions all require Phase 1 ESAs.
