Recognized environmental conditions (RECs) can be identified by looking at documents, inspecting the environment, and talking to current and past property owners, managers, and renters. These include things like waste, spills, and pollution. The purpose of a Phase 1 Environmental Site Assessment (ESA) is to give a lender, buyer, or owner a solid foundation on which to base their evaluation of the property’s possible environmental concerns.
