Most REAs provide all the appropriate inquiries into the current and previous ownership and uses of the subject property consistent with good commercial and prudent environmental practices in an effort to minimize liability prior to purchasing property, and follows, at a minimum, the latest protocols set forth by The American Society for Testing & Materials (ASTM) Standard E1527, Standard Practice for Environmental Site Assessments, Phase I Environmental Site Assessment Process and and U.S. Environmental Protection Agency's All Appropriate Inquiry (AAI) Final Rule 40 CFR Part 312.
EPA’s AAI rule further requires an environmental assessor to also qualify as an environmental professional. An environmental professional is someone with sufficient education, training, and experience to exercise professional judgment and develop opinions and conclusions. Such an environmental professional must have:a state or tribal issued certification or license and three years of relevant full-time work experience; or a Baccalaureate degree or higher in science or engineering and five years of relevant full-time work experience; or ten years of relevant full-time work experience.
