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.

CONSTRUCTION PHASE WATER QUALITY
An Erosion Hazard Assessment has been carried out for the proposed development – refer to
Appendix I for a copy of the completed Noosa Council form. As a result of this assessment, it
was determined that the site is a ‘low’ risk. During the construction phase of the development,
an Erosion and Sediment Control Program (ESCP) will need to be implemented to minimise
water quality impacts. A detailed Erosion and Sediment Control Program will be employed
throughout the site.

Details of the ESCP measures shall be provided on the operational engineering drawings for
the site earthworks and civil engineering works. The contractor shall be responsible for the
provision of the construction phase water quality objectives which shall be enforced by the
preparation and implemention of an Erosion and Sediment Control Program.

The ESCP shall be provided to all people involved with the construction, including sub-
contractors, private certifiers and regulators. These guidelines will be formed in accordance with
the Healthy Waterways Fact Sheet ‘Erosion and Sediment Control Management Plans’ and the
‘Best Practice Erosion and Sediment Control Guidelines.’
