      The Act requires that appropriate action be taken to report that environmental harm is occurring or has
      the potential to occur, unless the harm is authorised under an environmental protection policy, an
      environmental management program, a development approval, or an environmental protection order.
      This is known as the “Duty to Notify”. Failure to fulfil this duty is an offence and may result in prosecution.
