                                                                                                       Development Application


   7.2      Operational Phase


   7.2.1      Pollutants
   The key pollutants typically generated during this phase for the entire catchment are shown in Table 18.


   Table 18: Pollutant typically generated during the operational phase

     Pollutant                                            Potential Source
     Litter / Gross Pollutants                            Waste materials, food, food packaging etc.
     Hydrocarbons                                         Fuel and oil spills, dispensing areas, car park
     Nutrients (N & P)                                    Nitrogen, Phosphorus
     Sediments                                            Aggregates bins, wind deposits and car trails
     Surfactants                                          Detergents, cleaning agents


   The development site has two catchments area based on the architectural, landscape, topography and the
   proposed stormwater measures adopted. Appendix D shows the catchment area boundary and Table 19 below
   shows a breakdown of the key pollutants generated by the catchment.


   Table 19: Catchment characteristics

     Catchment                                                    Pollutants Generated
     A:
     Paypoint building roof                                       TSS, Gross Pollutants
     Light vehicle fuel dispensing area and roof                  Nutrients
     Driveways & Landscape                                        Hydrocarbons (Light)
     Vehicle car parking                                          Hydrocarbons (Heavy)
     B:
     Landscape area                                               None


   7.2.2      Water Quality Objectives
   The total area of the site being developed is less than 2,500m² therefore the development is not required to
   achieve the TN, TP and TSS pollutant reductions outlined in the Queensland State Planning Policy (SPP) July
   2014.


   7.2.3      Stormwater Treatment Philosophy
   Waterways and other aquatic environments are valued by the community for their social, cultural, economic and
   environmental benefits. Urban runoff, contaminated with nutrients, sediment and other pollutants adversely
   impacts theses valued resources. Water Sensitive Urban Design (WSUD) is a holistic approach to the planning
   and design of urban landscapes that minimises theses negative impacts. This approach is used on this project to
   select the treatment options that considers the civil, landscape and ecological aspects of the site.


   7.2.4      Source Controls
   Rubbish bins can be an effective source control for litter and are appropriate for most developments. Bins will be
   placed in appropriate areas (such as buildings and staff amenity) to encourage thoughtful waste disposal.
