Information Required

2. Provide a detailed Erosion and Sediment Control Management Plan, prepared by a
CPESC or RPEQ, which includes information on, but not limited to:
        2.1. Staging of the works and how each stage will be stabilised immediately after
        being completed;
        2.2. How areas that are not part of the final cut/fill pad but will be disturbed as part
        of the works (access tracks, manoeuvring areas, etc.) will be stabilised in the short
        and long term;
        2.3. How “dirty” water will be managed;
        2.4. How “clean” water will be diverted from the destabilised area;
        2.5. How will diversion drains be stabilised, namely the ones that divert clean
        water;
        2.6. Maintenance regime of the proposed controls;
        2.7. Where the topsoil will be stockpiled and how it will be stabilised.

3. Provide CPESC or RPEQ certification that all proposed E&S controls, for each of the
proposed construction stages, have been sized in accordance with relevant standards
and legislation, and suitable contingency measures will be available onsite, or able to
be deployed to site prior to being required.

Response

An Erosion and Sediment Control plan accompanies this response. Note that the control
measures outlined in the report have been depicted on drawing 1995-C1101.

Issue
Building pad levels and building envelopes.
Information Required
4. Update the earthworks plan (DWG 19553-C1100A) to include minimum building pad
levels in order to demonstrate compliance with Condition 35.
5. Update the earthworks plan to show building envelopes and the current level of the dam
top-of-embankment on Lot 8 and demonstrate compliance with Condition 32(d) of DA
approval RAL19/0018.
6. Either remove the extension proposed for the dam on Lot 8 or reduce the building
envelope on this lot so that the enlarged dam does not encroach into the building envelop.
