These impacts must be identified, evaluated and managed to minimise the risks. The OceanaGold Heath, Safety, Environment and Community (HSEC) compliance standards are an integral part of OGNZL’s business and provide the basis for a HSEC management system. The implementation and maintenance of the HSEC management system provides the means to manage and minimise risks, comply with legislation and OceanaGold Standards, and provides the framework for continuous improvement in Health, Safety, Environment and Community management and performance. HSEC Compliance Standards follow a hierarchical structure where documents must meet and support the requirements of those of higher levels (see Figure 1). This PHMP sits in the fifth tier as an Operation Specific Document. The scope of the HSEC Compliance Standards cover all activities undertaken by OceanaGold employees and contractors that have the potential to affect Health, Safety, Environmental and Community performance. The HSEC Compliance Standards apply to all operations and facilities, including the entire lifecycle of operations, from exploration through to operation and closure, until lease relinquishment occurs.
