ENGINEERING ISSUES

Issue relating to NC Item 1-3
Erosion and Sediment Control Plan (E&SCP)
The proposed staging of the works indicates that each stage will involve the
disturbance of large areas – approximately 100,000 m2 in total for all 3 stages
(1,220m3 of material expected to be excavated).
The proposed E&SCP for the site indicates that sediment fences are to be used with
the dual purpose of containing sediment and also functioning as clean water
diversion drains – since sediment fences are porous, it is expected that water
coming from outside the site must be treated as well.
Though 2 dams are proposed, there is no indication that these will be used as
sediment basins (or other water treatment structures) during the proposed works.

NC Information Required for Item 1
Demonstrate how Performance Outcome PO14 of the Water Quality and Drainage
Code will be achieved.
