    CONCRETE MIXER CLEAN-UP
Fully contain concrete waste washed from trucks and mixer units on-site and store where it cannot be washed from
the site, harming the environment.

    EXPOSED AGGREGATE CONCRETE SURFACES
•     Builders need to demonstrate how they intend to prepare exposed aggregate surfaces without allowing cement
      residue to flow into stormwater drains or waterways.
•     Where practicable, wash cement residue onto pervious surfaces or fully contain it within temporary sediment
      dams created from tightly stacked sand bags.
•     When suitably dry, shovel cement residue into a waste disposal bin.
•     At no time should cement residue or wastewater run-off enter the roadside gutter.
This may make it impractical on some sites for exposed aggregate driveways to be constructed. In such cases,
an alternative driveway finish must be used.


Storage of materials on hard surfaces                                SEE FACT SHEET 7



Whenever possible, materials should be stockpiled within the sediment
control zone and, where necessary, covered with waterproof sheeting to
minimise the potential for transport of sediments in stormwater.
Materials may be temporarily stored on hard surfaces only where it is
necessary to place erodible material on hard surfaces to undertake
work and no other reasonable options are available.

Grouped building lots                    SEE FACT SHEET 8



When one builder controls more than one building lot, combined-lot sediment control structures may be placed
down-slope if:
•     the combined sediment control measures provide a level of protection at least equal to that provided by
      individual lot protection
•     The builder accepts responsibility for the ongoing monitoring and maintenance of sediment control devices
•     suitable drainage and erosion control measures are applied to each building lot
•     a suitable sign is placed in a prominent location outside each lot and/or at the entrance of the
      estate indicating such controls are in place.
