Site Directive (also referred to as Limited Site Directive)

The Transaction Screen (see ASTM E 1528-93, Environmental Site Assessments) is an inquiry process designed to meet CERCLA’s “innocent landowner” defense, but does not require the judgment of an environmental professional. It includes a questionnaire with guidelines for interviewing owners and occupants of a property, observing site conditions, and conducting limited research. Based on the results, the user can determine whether additional information is required, proceed to a Phase I ESA, or research other areas of concern. The same type of process can be applied to other lines of inquiry.
