10. Acid Sulfate Soils

10.1 General

A preliminary acid sulfate soil (ASS) investigation was conducted by Coffey Geotechnics Pty Ltd (Coffey)
for the proposed Girraween Sporting Complex on 25 January 2010, This assessment was conducted in
accordance with State Planning Policy 2/02 - Planning and Managing Development Involving Acid
Suffate Soils and associated Guideline, and the former Department of Natural Resources & Mines’
Guidelines for Sampling and Analysis of Lowland Acid Sulfate Soils (ASS) in Queensland 1998 (QASSIT,
1998).

The results of investigations confirmed the soils on the site do not contain actual acid sulphate soils
(AASS) or potential acid sulphate soils (PASS). These results are consistent with the geomorphology of
the site and other investigations in the vicinity. The management of soils on the site are therefore not
subject to the requirements of State Planning Policy 2/02. Specific ASS management and an acid sulfate
soils management plan (ASSMP) are therefore not required in the excavation and handling of these
soils.

In general terms, the Soil Surveys report concludes that acid soils do exist onsite.

10.2 Objectives

» To comply with environmental legislation relevant to acid sulfate soils (e.g. Sustainable Planning Act
2009, Environmental Protection Act 1994).

» To minimise disturbance to any acid sulfate soils, should they be identified within the project area
during the construction process.

10.3 Requirements

If at any stage through the construction of the road realignment, AASS, PASS or soils significantly acidic
in nature appear to be present, work should be ceased and the following shall occur:

» Testing of the soils of concern should occur in accordance with the Guidelines for Sampling and
Analysis of Lowland Acid Sulfate Soils in Queensland (QASSIT, 1998).

» Should the presence of ASS or PASS be confirmed, lime dosing rates should be calculated and then
applied to the soils in accordance with the QASSIT Guidelines (1998).

» Where identified, acid soils should be managed appropriately to prevent any stormwater runoff to
adjoining wetland areas and waterways.

10.4 Responsibilities

10.4.1 Construction Manager
The Construction Manager will be responsible for the following:

» Initiating any analysis and necessary treatment works of any AASS, PASS or soils significantly acidic
in nature.
