DERM Permit number: SPCE01881811

The only form of dredging to be undertaken as part of this permit is the relocation of clean
sand for the purposes of beach nourishment, backfilling, filling material for Stage 1 works
and for an interim navigation channel.

Disturbance to acid sulphate soils (ASS) is to be avoided as far as practicable, should the
works disturb ASS the works must comply with Instructions for the Treatment and Management
of Acid Sulfate Soils, 2001, Queensland Government, or any updates as they become available.

Dredging works must ensure that no significant stability or hydrological changes to tidal
hydrodynamics, wave or current conditions occur either directly or indirectly in the immediate
area that could induce detrimental impacts on the adjacent coastline or beach profiles.

Material dredged under this permit must remain within the active Noosa River system, this
includes beach nourishment and material placed in underwater containment and dredged
material is not permitted to be stockpiled on land.

 

The dredge area is to be checked prior to completion of the works and all waste materials
{including anchor blocks and ropes used during the dredging) are removed prior to departure.

The operator of this development permit must monitor the visual impact of the dredging
activity on the environment by undertaking the following: |
(a) Daily observations and recording of the extent of any turbidity plume caused by }
dredging; and
(b) Daily observations and recording of the period of time the turbidity persists.

In the event that the administering authority requires water quality sampling or dredge material
sampling, all determinations of the quality of the samples must be:
(a) made in accordance with methods prescribed in the latest edition of the Department of
Environment and Resource Management Water Quality Sampling Manual; and
(b) carried out on samples that are representative of the discharge.

The measurement and reporting of any monitoring and\or nuisance levels (air, noise) must be
undertaken by a person or body possessing appropriate experience and qualifications to perform
the required measurements.

If in the opinion of an authorised person, monitoring indicates that the works are a nuisance,
the operator must:
(a) address the complaint including the use of appropriate dispute resolution if required; or
(b) immediately implement abatement measures so that the works do not result in any further
environmental nuisance.
