          Inspection for any leaks, spills or potential contaminating activity must be performed on a
           regular basis (at least daily).
          Remove accumulated sediment or other contaminants from sediment/ pollution control devices
           on a regular basis.
          All erosion and sediment control measures must be inspected within 24 hours of expected rain
           and within 18 hours of a rainfall event.

5.5.6 Responsible Person Or Organisation

The contractor shall be responsible for the implementation and maintenance of the Erosion and
Sediment Control Measures.

5.5.7 Reporting / Review

Records such as licences, approvals, permits and inspection reports must be reviewed on a regular basis
(e.g. at least monthly) to ensure that legal compliance is met, complaints are reviewed and systems are
working to prevent contamination.




5.5.8 Corrective Actions

          Perform clean-up of any spills immediately.
          Any mud or sediment which is tracked onto public roads is to be immediately removed using dry
           clean-up methods i.e. shovel and broom.
          Remove or relocate any stockpiles of waste where there is a reasonable risk of erosion and
           sedimentation.
          Replace or repair sediment or pollution control devices if they are not maintained in good
           working condition.


6         CONCLUSION
This Stormwater Management Plan demonstrates that under the proposed concept plan stormwater
quality and quantity treatment is achievable to the levels required by State Planning Policy July 2017.

Detention and treatment will be provided in the form of a combined treatment / detention tank within
the proposed development lot.

The installation of detention and treatment on site will ensure that runoff conditions from the
developed site are consistent with the pre-developed scenario. Regular maintenance of the detention
and treatment systems will be undertaken to ensure that the systems are functioning as designed and
that the State Planning Policy and Noosa Council requirements are being met.

Any groundwater discharged from site will be tested and assessed for its levels of acidity and treated as
required to ensure that the pH is consistent with that of the downstream environment.
