Dredging operations

The only form of dredging to be carried out is the relocation of accumulated clean sand for the
purpose of beach replenishment, maintaining navigational channels and maintaining flood
mitigation profiles.

 

4-G2

Approved programs of dredging include:

1. aprogram to trial recycling of clean uncontaminated sand from Noosa Spit Beach to Noosa
Main Beach using a submarine sea shifter for a two (2) year period (being 31 December 2009
to December 2011 inclusive); and

2. the permanent recycling of clean uncontaminated sand from Noosa Spit Beach to Noosa
Main Beach using a submarine sand shifter to be constructed on or before the expiry of the
abovementioned trial recycling program.

 

4-G3

All dredging works are to be conducted within the designated ‘area of sand extraction’ for
placement in the designated ‘area of sand deposition’ as per the approved plan in Schedule 5 —
Figure 3 of this environmental auhtority.

 

4-G4

Within two (2) months of completion of the permanent recycling facility, all structures and
associated equipment used for the trial program must be removed and any disturbed areas must
be appropriately stabilised and rehabilitated.

4-W1 The only contaminants permitted to be released to any waters (including the bed or banks of such
waters) are sediments necessarily disturbed during dredging, and the placement of dredge
material.

4-W2 There must be no impact as a result of the sand shifting facility or associated works on the Noosa
River, including but not limited to, impact on water quality, hydrology and ecology.

4-W3 Release points
Contaminants that may cause environmental harm must not be directly or indirectly released to
any waters from the authorised place at any location other than those listed below:
1. wastewater discharge point from the dredged material placement pipe or the discharge point

of any drainage system used during the transfer of dredge material; and

2. dredging action while extracting material.

4-W4 Environmental impact investigation

The holder of the environmental authority must investigate, at six (6) monthly intervals, the
environmental impacts of the activity and submit a report outlining the investigation and its
findings to the administering authority within one (1) month of the final monitoring result being
received for that period. The report must address the following:

1. volume of material relocated; and

2. current profiles across the ‘area of deposition’.
