RISK BASED ENVIRONMENTAL ASSESSMENT
AN OVERALL RISK ASSESSMENT ADDRESSES THE UNDERLYING PHYSICAL RISKS, UPON WHICH THE NON-PHYSICAL RISKS DEPEND:
Environmental and Geotechnical Risks
Legal and Permitting
Social and Political
Financial
Safety and Human Health
Operational Risks
RISK BASED ENVIRONMENTAL ASSESSMENT
IMPACT COMPENSATION
RESIDUAL IMPACTS
IMPACT MITIGATION
