In November 2006, the EPA created a new set of standards to conduct All Appropriate Inquiry (AAI) through Phase I Site Assessments. AAI Site Assessments involve more research and interviews than ASTM 1527-00, the former Phase I standard. While both guidelines are still accepted, AAI is the highest level of liability protection available. ASTM has also updated its standard (1527-05) to comply with AAI regulations.
