7.0     APPLICATION TO NOOSA COUNCIL REGULATION
Development involving ASS must comply with the requirements of state and local regulations pertaining to
ASS. Locally, NC has developed the ASS Overlay Code, and its attendant guidelines, as part of the Noosa
Plan 2020. The purpose of the ASS overlay code is to ensure that the generation or release of acid and
metal contaminants from disturbance of ASS does not have adverse effects on the natural environment,
built environment, infrastructure or human health. This is achieved through compliance with the following
development performance outcomes:
    a) development ensures that the release of acid and associated metal contaminants into the
       environment is avoided by either:
            i.     not disturbing ASS when excavating or otherwise removing soil or sediment, extracting
                   groundwater or filling land; or
           ii.     treating and, if required, undertaking ongoing management of any disturbed ASS and
                   associated drainage waters.
While the site is located within ASS Overlay Code Area 2, being situated between RL 5 m and RL 20 m
AHD, the proposed works will not involve disturbance of soil or groundwater conditions at or below 5 m AHD
and therefore does not have potential to disturb ASS.
Based on our site observations, assessment of the regional geology, published ASS risk mapping proposed
works are not likely to present any significant risk associated with possible ASS disturbance.
The proposed development is therefore deemed to meet performance outcome PO1 of the NC’s ASS
Overlay Code (i.e. development does not disturb ASS).


8.0     RECOMMENDATIONS
Proposed earthworks associated with the development would have a negligible risk of encountering ASS or
affecting groundwater conditions which may impact ASS prone areas. The proposed development may
therefore proceed without need for any further specific ASS or dewatering management measures. No
further site assessment regarding ASS is warranted for the proposed development.
