Also known as an Environmental Site History, a PSI is a study of the background or history of land ownership, occupation and use over time. The aim is to determine if activities of environmental significance have occurred on the land and determine if further assessment is warranted for the proposed use of the site. Often this study is accompanied with a Site Contamination Declaration Form (PlanSA Practice Direction 14).
