and Managing Development Involving Acid Sulfate Soils’ with reference to the SPP
Guideline: Acid Sulfate Soils’, the Guidelines for Sampling and Analysis of Lowland Acid
Sulfate Soils in Queensland 1998° and the Queensland Acid Sulfate Soil Technical Manual:
Soil Management Guidelines’. (Refer to: www.nrm.qld.gov.aw/land/ass/policies).

If the proposed development will involve excavations of soil or sediment below 5m AHD
that total between 100m? and 1000m? in volume, or involves filling with between 500m’ and
1000 m? of material then NRMW advise that ASS investigations and management should be
undertaken in accordance with the above-mentioned documents to the satisfaction of
Council, however do not need to be sent to NRMW for review.

Irrespective of the volume of disturbance, specific reference should be made to Section 9 of
the SPP Guideline that discusses treatment levels required to treat all potential and existing
acidity. These treatment levels are based on mass (tonnes) of soil to be excavated and levels
of sulfidic sulfur (percentage). For low level, medium level, high level and very high level
of treatment, the Draft SPP Guideline provides advice on suitable management measures.
For extra high treatment levels, ie where greater than 25 tonnes of agricultural lime is
necessary, a detailed environmental management plan is required. For disturbances less than
1000m?, NRMW can provide assistance to local governments when developments entail an
extra high treatment category, and for smaller scale disturbances, the guidelines associated
with the SPP should be consulted.

THIRD PARTY ADVICE

Aboriginal Cultural Heritage Act 2003

Under section 23 of the Aboriginal Cultural Heritage Act 2003 a person who carries out an
activity must take all reasonable and practicable measures to ensure the activity does not
harm Aboriginal cultural heritage (the "cultural heritage duty of care"). Maximum penalties
for breaching the duty of care are $750,000 for a corporation and $75,000 for an individual.

You will comply with the cultural heritage duty of care if you are acting in accordance with
gazetted cultural heritage duty of care guidelines. An assessment of your proposed activity
against the duty of care guidelines will help determine whether or to what extent Aboriginal
cultural heritage may be harmed by your activity. It will also help determine if you need to
undertake a search of the cultural heritage database and register.

If following an assessment of the duty of care guidelines you believe cultural heritage may
be harmed by your proposed activity, you should contact the Cultural Heritage Coordination
Unit for further advice on (07) 323 83838 or e-mail cultural [email protected].
