18 July 2019


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 will be provided in the form of a combined bioretention/detention basin located along
the Northern boundary of the site and a detention tank located under the main entry to the new
building. The combined bioretention/detention basin will provide stormwater treatment for the
proposed development.

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.
