• Primary project site and related facilities that the client and its contractors develops or controls; • Areas potentially impacted by cumulative impacts for further planned development of the project, any existing project or condition and other project-related developments; and • Areas potentially affected by impacts from unplanned but predictable developments caused by the project that may occur later or at a different location. Risks/Impacts should be assessed for all stages of the project cycle including: • Pre-construction; • Construction; • Operation; and • Post-closure. 151
