What is the purpose of Phase I and Phase II Environmental Site Assessments, and when are they typically required?

• A. Phase I identifies potential contamination; Phase II involves sampling if Phase I flags risks; required by lenders and purchasers
• B. Phase I identifies potential contamination; Phase II involves expansion of the facility; required by tenants only
• C. Phase I is the remediation step; Phase II is auditing; not used
• D. Phase I is not related to contamination; Phase II is for permits

Answer: (B)

Phase I and Phase II Environmental Site Assessments are used to evaluate environmental risk in real estate transactions. Phase I is a non-intrusive review of the site's history and current conditions—looking at records, prior uses, aerial photographs, interviews, and a brief site visit—to identify any indicators of potential contamination. If Phase I flags risks, Phase II involves sampling and laboratory analysis of soil, groundwater, and sometimes building materials to confirm whether contamination is present and to determine its extent. These assessments are typically required by lenders and purchasers as part of due diligence to assess financial and regulatory risk, with Phase II only performed when Phase I suggests potential issues.
