Environment resources

NOPSEMA has developed a series of advice documents to inform and assist stakeholders to interpret and meet the requirements of the Offshore Petroleum and Greenhouse Gas Storage (Environment) Regulations 2009 (Environment Regulations). Policy documents provide NOPSEMA's interpretation of legislative requirements and guideline documents provide guidance on how to meet those legislative requirements. Guidance note documents provide NOPSEMA's expectations on a specific environmental management topic and information papers provide further information, background and practices on a topic to foster improved environmental management outcomes.
