                 Best practice measures shall be utilised during the construction phase to minimise the potential impacts
                 of the pollutants mentioned above. Detailed Erosion and Sediment Control Management Plans should
                 be developed in conjunction with the Operational Works design prior to construction works commencing
                 in accordance with the International Erosion Control Association (IECA) - "Best Practice Erosion and
                 Sediment Control (BPESC) document" and overseen by a Certified Professional in Erosion and
                 Sediment Control (CPESC) or Registered Professional Engineer Queensland (RPEQ).
                 Through their principal contractor, the developer shall be responsible for ensuring that temporary
                 sediment and erosion controls are installed and maintained correctly.
                 5.6.1.1 Pollutants
                 The pollutants that would typically be generated during the construction of the proposed development
                 are outlined in Table 2.

                  Pollutant               Source
                  Litter                  Paper, construction packaging, food packaging, cement bags, offcuts
                  Sediment                Unprotected exposed soils and stockpiles during earthworks and building
                  Hydrocarbons            Fuel and oil spills, leaks from construction equipment
                  Toxic Materials         Cement slurry, asphalt prime, solvents, cleaning agents, wash waters e.g.
                                          from tile works)
                  Ph Altering             Acid sulphate soils, cement slurry
                  Substances
                 5.6.1.2 Potential Impacts
                 Construction activities can have a potential impact on water quality. Removal of vegetation, earthworks
                 and changes to drainage patterns can result in erosion and sediment being washed into waterways.
                 This can impact the physical-chemical parameters of the receiving water, the decline in the health of
                 aquatic ecosystems, and overall aesthetics. The potential impacts on the development site's
                 surrounding receiving waters will be minimised during the construction phase with typical measures
                 outlined below. These measures should be adequately detailed on erosion and sediment control plans
                 as part of the development's Operational Works application.
                 5.6.1.3 Performance Objectives
                 The amount of runoff traversing and discharging from the site while under construction should be kept
                 to a minimum. This will restrict soil erosion and mobilisation of sediments and pollutants through and
                 off the site. During the construction phase, stormwater runoff at discharge points shall comply with the
                 objectives detailed in QLD SPP (July 2017).
                 5.6.1.4 Control Measures
                 The following are typical treatment measures that should be implemented before the commencement
                 of any construction works. Detailed erosion and sediment control procedures shall be based on the
                 erosion and sediment control plans lodged at the Operational Works phase.
                 5.6.1.5 Maintenance
                 Maintenance of erosion and control treatment measures (such as sediment fences) will be undertaken
                 if it is observed that they have not been properly installed or the capacity of the measure falls below
                 75%.
                 5.6.1.6 Minimise Disturbance Area
                 Clearing of land is to be minimised to areas planned to be actively under construction in the near term
                 (e.g. within the next 3-6 months).
