3.1.4        Monitoring
      The Site Manager shall carry out monthly surveillance of on-site water storages and treatment systems.
      Site inspection of water storages and treatment systems shall be carried out by the Site Manager where practicable
      prior to anticipated runoff-producing rainfall and immediately following the event.
      The inspections should consider:
      -    condition of banks and batters;
      -    condition of inlet and outlet zones, including structure integrity, possible clogging, excessive sediment deposition
           or erosion;
      -    pollutant levels within any treatment devices; and
      -    weed infestation.

      Prior to a release event from the quarry pit voids, the Site Manager shall arrange water samples to be collected for
      laboratory analysis at the monitoring frequency and locations provided in Table 13 – Water Monitoring Frequency
      and Locations.

      The Site Manager may engage the services of a suitably qualified and experienced person to conduct the water
      quality sampling and review monitoring results to provide advice in relation to the water quality management if a
      complaint is received or if requested by the administrating authority.
      Any surface water sampling will be undertaken in accordance with The Department of Environment and Heritage
      Protection (EHP) Monitoring and Sampling Manual, September 2009 or subsequent editions.

3.1.5        Audit and Review
      The effectiveness of the stormwater, erosion and sediment control management strategies will be reviewed
      periodically and at least once every three years.

3.1.6        Reporting and Responsibility
      Complaints or incidents regarding stormwater are to be reported to the Site Manager as soon as practicable and
      recorded on the complaint register.
      The Site Manager shall maintain a record of surveillance monitoring of on-site water storages and treatment systems,
      of any corrective actions taken and complaints or incidents reported.
      Records including results of any monitoring program undertaken on-site and complaint or incidents will be kept for a
      minimum of five years for inspection by relevant statutory authorities.

3.1.7        Identification of Incident or Failure to Comply
