There are generally lower slopes and more areas suitable for the implementation
of sediment ponds and diversion channels on site. It is noted that correctly sized
sediment ponds were not utilised during construction of Stages 1 and 2.

There will be extensive use of sediment fencing, diversion channels, sediment
ponds during the construction of Stage 3 works. It is expected that Council
representatives will be invited to inspect works on an agreed frequency to ensure
that all works are acceptable. The site superintendent will be responsible for the
ongoing checking and deployment of sediment controls as the bulk earthworks
and civil works progress.

Exposed areas will be hydromulched as soon as practicable after bulk
earthworks and civil works to stabilise exposed areas. Hydromulching will occur
no later than 7 days after completion of works in an area.

Bulk earthworks and civil works will be completed and the site will be left
stabilised, with all erosion and sediment controls left in place, prior to any building
contracts commencing.

A pluviometer will be installed on site (with telemetry link) to accurately record
rainfall and send alerts (via SMS) to site staff when high levels of rainfall occur.

Water quality equipment will be installed on site to enable checking of
performance of the erosion and sediment control equipment.

it is noted there are two differing Figure 4.1A (i). The figure on page 22 is
different to the figure included in the Sediment & Erosion Control MP. Please
ensure that this plan is consistent and please show existing cutoff drains that are
proposed to remain and any further cutoff drains to be constructed.

There does not appear to be any E&SC measures for Phase 1 Figure 4.2A other
than rock check dams in the permanent cutoff drains. Please ensure all line
types are detailed within the Legend. Further, please highlight which areas will
be disturbed during Phase 1.

Please check that all other drawings are current and that the Legends show what
all line types are denoting. It is noted that Figures 4.1 to 4.5 do not currently
Show ail line types.

Please provide drawings that clearly demonstrate the stage of works being
undertaken and what measures are in place to control these works. Clearly
indicate what works are occurring during Phase 1, 2, 3, & 4 on the plans and
show the E&SC measures for each of these phases.

Please provide details on sizing of proposed sediment basins for the site as
shown on Figure 4. 1A(iii).

Please provide details of the size of the proposed cutoff drains. Further, please
indicate what storm event will they be able to cope with.

65.1 ~ 65.6 The inconsistency between these plans has been resolved and cutoff drains are

now indicated on the amended plans.
