15. Where proprietary devices are proposed as an option- demonstrate that the methodology for
    pollutant reduction modelling for the proprietary device is fully endorsed by Stormwater Australia
    for their pollutant reduction efficiencies, consistent with the Water by Design MUSIC modelling
    guidelines, and that the applicant is satisfied with the maintenance costs likely to be involved with
    maintaining the water quality treatment train to perform as modelled.

Response:
Refer correspondence from Morgan Consulting Engineers included within Attachment 3 which includes
documentation from Humes Water Solutions which demonstrates that the methodology for the
pollutant reduction pollutant modelling is consistent with the Water By Design MUSIC modelling
guidelines. Additionally, the documentation demonstrates compliance with the Draft Stormwater
Australia – Stormwater Quality Improvement Device Evaluation Protocol.


16. Provide the MUSIC modelling files used to size and design the proposed water quality treatment
    train.

Response:
Refer attached MUSIC modelling files.


17. Provide a preliminary drainage plan to demonstrate that drainage from the proposed water quality
    treatment train can be achieved.

Response:
Refer correspondence from Morgan Consulting Engineers included within Attachment 3 and amended
Stormwater Management Plan which includes a preliminary drainage plan demonstrating that
drainage from the proposed water quality treatment train can be achieved.


18. Demonstrate the proposed water quality treatment train will not increase the amount of
    excavations needed into Acid Sulphate Soils and will not be subject to groundwater influence.

Response:
Refer correspondence from Morgan Consulting Engineers included within Attachment 3 which
confirms that an Acid Sulfate Soils Assessment and Management Plan will be provided and that
groundwater influence is not considered possible.


The Information and Referral Stage of IDAS has now concluded. We ask that you now provide details
of adjoining owners in order that we may commence the public notification of the application.

Should you have any questions with respect to the above, please do not hesitate to contact me direct.

Yours faithfully
