It is the responsibility of Shadforth Project Management Team to ensure that all potential and actual acid
sulphate soils are identified onsite, prior to earth works commencing. Treatment of acid sulphate soils is
conducted, in accordance with the soil treatment section in the Queensland Acid Sulphate Soil Technical Manual
2002. In addition, an Acid Sulphate Soil Management Plan IMS-04-04 may be developed to assist in the
management of acid sulphate soils.

Potential Acid Sulphate Soils

Potential acid sulphate soils are soils containing iron sulfides (commonly pyrite), which have the potential to
produce sulfuric acid if they are drained or excavated. Preliminary investigation can be carried out using the
field test for peroxide oxidised pH (pHFOX), and identification confirmed by laboratory analysis.

Actual Acid Sulphate Soils

Actual acid sulphate soils are soils that have already undergone oxidation to produce acid. This results in a soil
pH of less than 4. Actual acid sulphate soils often exhibit a yellow and/or red mottling in the soil profile. If these
soils still contain sulfides, they have the potential to produce more acid if allowed to oxidise further. This would
be identified by a further decrease in pH. Actual acid sulphate soils should also be confirmed by laboratory
analysis.



Cultural Heritage

Shadforth take all reasonable and practical measures to ensure the protection and preservation of any potential
cultural heritage. Shadforth operations have the potential to impact cultural heritage through the use of vehicles
and machinery, moving earth, and by clearing vegetation.

A general duty of care is required for the following statutory provisions.

▪   Aboriginal Cultural Heritage Act (Old) 2003
▪   Queensland Heritage Act 1992
▪   Australian Heritage Council Act 2003
▪   Aboriginal and Torres Strait Islander Heritage Protection Act 1984

Most cultural heritage artefacts are identified and managed by the client prior to construction. However, if any
sign of potential artefacts are discovered throughout the duration of the project, work ceases immediately, the
area is isolated, and Shadforth Project Manager informed. No further work is undertaken until the relevant
authorities give clearance. All identified cultural heritage artefacts are documented on the Cultural Heritage
Artefacts Form IMS-05-66.

A search request can be undertaken prior to construction using the following website www.datsip.qld.gov.au

Pest Management

Shadforth undertake all reasonable and practical measures to ensure that invasive species are not transported
into unaffected areas during construction. Spreading of weeds and weed seeds, plant pathogens, insects, and
pest animals, has the potential to affect natural ecosystems. A general duty of care for the management of
invasive species is imposed by the following legislation.

▪   The Land Protection (Pest and Stock Route Management) Act 2002
▪   The Land Protection (Pest and Stock Route Management) Regulation 2003
