ASTM Transaction Screen Assessment

Phase I Environmental Site Assessment (ESA)

A Phase I Site Assessment is the gold standard for evaluating the environmental liability associated with a real estate transaction. The Phase I helps clients meet the legal requirements for the CERCLA innocent landowner defense. The Phase I ESA’s are done by Environmental Professionals (EP) utilizing ASTM E1527-13 and EPA’s All Appropriate Inquiry (AAI)standards. A Phase I ESA includes a site inspection by an Environmental Professional; historical research including historical aerial photographs, Street Directories, Sanborn Atlases, and Topographical Maps; Permits; Regulatory research including EPA and DEP Databases, Building Permits, Planning Records, Fire Department records, and Health Department reports; and Interviews with site owners, occupants, and tenants.


Transaction Screen Assessment

A Transaction Screen Assessment is a cost-effective environmental due diligence report that is prepared in accordance with ASTM 1528-14 Standard Practice for Limited Due Diligence. A Transaction Screen Assessment is essentially a scaled down version of a Phase I ESA. A Transaction Screen includes a site visit, review of regulatory records, interviews with key personnel, and limited historical research.


Records Search with Risk Assessment (RSRA)

The RSRA is a risk screening tool performed by an Environmental Professional who analyzes data to determine whether a property is a “low risk” or a “high risk” for contamination. A RSRA includes a review of EPA and DEP Databases; a review of Sanborn Fire Insurance Atlases and/or historic aerial photographs; an Environmental Questionnaire; and a risk rating (Low or High).
