     6.5 Cultural Heritage

The Noosa River Spit was artificially reclaimed in 1978 and there has been significant dredging within the river over recent
years. There are no identified areas or items of cultural significance within the proposed area of the works, although a
cultural study can be undertaken if required.

If any potentially culturally significant items are found, the contractor will cease works immediately and advise the
Superintendent. The Superintendent will notify the traditional owners to seek their advice before works in that area can
continue.


     6.6 Waste Management

The sandy material from dredging / excavation will be used for filling containers, backfilling and foreshore nourishment within
the vicinity of the works. The sediment type is very consistent across the footprint of the works and is suitable for this
purpose.

Other wastes (rubbish etc) may be temporarily stored on site if adequately contained. The Contractor is responsible for
ensuring that all waste is disposed of at suitable onshore facilities. Every effort is to be made to ensure that litter and other
debris does not enter the waters. Any material or objects dropped onto the bed are to be recovered. Visual monitoring is to
be undertaken.

The seabed is to be checked prior to completion of the works. All waste materials (including anchor blocks and ropes used
during construction) are to be removed and not buried or left on the seabed.

The contractor is to implement an oil spill management plan.

It is not anticipated that any regulated waste will be generated as part of the works.


     6.7 Air Quality Management

Air emissions from plant and equipment are to be monitored visually to ensure air quality is acceptable throughout the works.
Exhaust is to be within the specifications of the equipment and all required maintenance is to be undertaken.
