      Treatment Device         Discussion
       Gross Pollutant
            Traps              A gross pollutant trap is a treatment device designed to capture coarse sediment,
                               trash and vegetation matter in stormwater runoff – discussed for each supplier
                               option below.


                               Site A Catchment:
                                    •   SPEL – 8 (Eight) Stormsacks: or
                                    •   Ocean Protect – 8 (Eight) Ocean Guards.


                                Site B - Northern Catchment:
                                    •   SPEL – 2 (Two) Stormsacks: or
                                    •   Ocean Protect – 2 (Two) Ocean Guards.


                               Site C - Southern Catchment:
                                    •   SPEL – 4 (Four) Stormsacks: or
                                    •   Ocean Protect – 4 (Four) Ocean Guards.


                               Proposed number of gross pollutant traps for development sites will be installed in
                               all major field inlets and gully pits within the development site parking and vehicle
                               areas.


         Proprietary
      Treatment Device         Proprietary filtration devices are designed to remove nutrients and sediments
                               from stormwater runoff – discussed for each supplier option below.


                               Site A Catchment:
                                    •   SPEL – 50 (Fifty) SPELFilters: or
                                    •   Ocean Protect – 85 (Eighty-Five) Stormfilters.


                                Site B - Northern Catchment:
                                    •   SPEL – 2 (Two) SPELFilters: or
                                    •   Ocean Protect – 5 (Five) Stormfilters.


                               Site B - Southern Catchment:
                                    •   SPEL – 2 (Two) SPELFilters: or
                                    •   Ocean Protect – 6 (Six) Stormfilters.


                               All runoff from the site will pass through the cartridge filters located within the
                               proposed stormwater detention tanks across the development site.
