Molinate Detections in MI Drainage System
After heavy rainfall events, detections of Molinate have been found at various locations throughout MI’s drainage system. These detections potentially place MI in breach of its Dept. Environment, Climate Change & Water (DECCW) licence to operate. The DECCW has been notified of the recent detections and in response, our monitoring and sampling program will be increased to ensure compliance. These detections are a timely reminder of landholder obligations regarding rice chemical use. All chemicals applied must be kept on farm for a minimum of 28 days prior to drainage. In the event of an unscheduled release of chemically treated water entering MI drainage within the 28 day period, the landholder must notify MI immediately to allow our risk management process to be enacted. We look forward to working with our customers to ensure best management practice and licence compliance. Please contact John Sutherland, Grant Gyles or Bart Challacombe on 6962 0200 for further information
MI Rice Environmental Monitoring Program
MI would also like to advise customers that it implementing the Rice Environmental Monitoring (REM) Program this season in accordance with its Water Management Works Licence No. IC5 issued by NOW.
To ensure MI customers are complying with the licence, rice growing must be within MI’s Rice Growing Policy guidelines. Policy guidelines include growing only on rice approved soils and any chemicals applied must be kept on farm for a minimum of 28 days. An updated copy of MI’s Rice Environmental Monitoring Policy will soon be available. To assist with best management practice, landholdings in single farming units are permitted to pool their annual entitlement and select the most suitable farm for rice growing. However individual flow rate share rules must also be considered when pooling annual entitlements.
