A0004-AA007595-AAL-01 SPEL Approval Request Letter · MCU14/0102.05

         installed to collect vehicle dispensing spillage, blown in rain and tanker delivery
         spillages.
         It is recommended to engage a suitably qualified hydraulic consultant to design
         the Fuel Dispensing Area (FDA), Uncovered Forecourt Area (UFA) and the tanker
         unloading area hydraulic management systems. Arcadis suggests the use of a
         specifically designed SPEL Puraceptor system to treat stormwater runoff in the
         Fuel Dispensing Area.
         Independent testing on the SPEL systems concluded the following removal
         efficiencies:
               97% Total Suspended Solids (TSS)
               100% >5mm Gross Pollutant Solids (GP)
               99.9% of light liquids (TPH) (certified discharge quality of 5ppm or less)
               >30% particulate specialisation of phosphorous and nitrogen.
               <0.1mg/L hydrocarbon content (minimum requirement is 10mg/L)
         A risk assessment has been completed by SPEL proposing to use a
         P.070.S.C1.2C Puraceptor for the site. The risk assessment has been included
         in Appendix J.
         The Puraceptor tank and associated infrastructure is to be installed prior to the
         stormwater infrastructure discharging to Council assets.


Please do not hesitate to contact me should you have any queries regarding the above.


Yours sincerely
