Information Request - 2212-32529 SRA

                                                                                                    2212-32529 SRA

        Volumes, indicates that the project will involve dredging up to 136,000 tonnes within the ‘dredge
        channel’ but the total amount of material required for the sand plugs and beach nourishment is
        144,500 tonnes. Therefore, it is unclear where the remaining 8,500 tonnes of material will be
        sourced and the characteristics of the material.
        This information is required for SARA to determine compliance with PO8 and PO13 of State
        Code 8 of SDAP.
        Action:
        Demonstrate that material from an alternative source to the ‘dredge channel’ is suitable for beach
        nourishment and construction of the sand plugs. In particular, confirm the following:
           the source of the 8,500 tonnes of material which is unaccounted for
           the characteristics of the material and whether it matches the receiving environment in
            terms of type and size
           that the material does not contain contaminants at unacceptable levels
           that the material is appropriate for the proposed use.

 Volume of Dredge Material

 3.     Issue:
        Based on the information provided, the amount of material to be dredged is unclear. Specifically,
        the Noosa Spit Coastal Protection Environmental Assessment prepared by BMT Commercial
        Australia Pty Ltd, dated 23rd November 2022, reference R.A10342.002.01_Environmental
        Assessment.docx and revision 01, indicates that the project will involve:
              dredging up to 85,000m3
              14,000m3 of sand to fill the northern sand plug
              17,000m3 of sand to fill the southern sand plug.
        However, contradicting this, Table 1.1 Summary of volumes and tonnages of the Memorandum
        prepared by BMT Commercial Australia Pty Ltd, dated 05/01/2023 and reference
        M.A10342.001_Revised-Design-Drawings-and-Dredge-Volumes, indicates that the project will
        involve:
              dredging up to 80,000m3
              11,450m3 of sand to fill the western sand plug
              10,85m3 of sand to fill the eastern sand plug.
        Action:
        Confirm the exact volume of material to be dredged and the volume of fill required for each sand
        plug in tonnes.
        Note: The total volume of material should inform your response to Item 2 of this request.

 Timing of Dredging

        The Letter prepared by BMT Commercial Australia Pty Ltd, dated 23 November 2022 and
        reference L.A10342.002.01.Information Request Response.docx, indicates dredging will most
        likely be undertaken between April and September.
