4.      Water Quality

4.1 Construction Phase


Potential exists during the construction phase for sediment to become mobilised by stormwater as suspended solids
from the erosion of exposed soil areas and stockpiles, and as a result of spillages from construction and plant
operations.

Stormwater quality during the construction phase of the development should be addressed in an Erosion and
Sediment Control Plan. The plan should address construction phase erosion and sediment control issues in
accordance with the Institute of Engineers Australia (Qld)Erosion and Sediment Control Guidelines. The Erosion and
Sediment Control Plan should also be in accordance with the Water Sensitive Urban Design Guidelines for South
East Queensland.


The following measures should generally be implemented prior to the commencement of construction:


     Education of all site workers in sediment and erosion procedures;
     Specified storage areas for construction materials and plant that are bunded to prevent any spillages from
     escaping; and
     Construction of silt fences and catch drains adjacent to the downstream boundaries to divert runoff to temporary
     sediment basins.


The following measures should be implemented during the construction phase of the project:


     Temporary sedimentation basins should be constructed in accordance with Council’s requirements;
     Silt fences should be erected downstream of all disturbed areas; and
     All erosion and sediment control devices should be regularly inspected and maintained following storm events.
