Environmental Risk and impact assessment methodology
In accordance with Regulations 13(5) and 13(6) of the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (OPGGS(E)), an environmental impact and risk assessment was undertaken to evaluate the impacts and risks arising from the planned operational activities (planned activities), the unplanned events (non-emergency and emergency events) and spill response activities.
Chevron Corporation has an established risk management framework developed specifically to meet Operational Excellence (OE) expectations for performing health, environment and safety (HES) risk assessments. Environmental risk assessments were undertaken in accordance with the Chevron Corporate HES Risk Management Process and the Chevron RiskMan2 Procedure, including the Chevron Integrated Risk Prioritisation Matrix. The approach generally aligns with the processes outlined in Australian Standard/New Zealand Standard (AS/NZS) ISO 31000:2009 Risk Management and Handbook 203: 2012 Managing Environment-Related Risk.
