          Instructions for the Treatment and Management of Acid Sulfate Soils (Queensland Government,
           July 2001);
          Acid Sulfate Soils Management Plans for Queensland (Dear et al, June 2000); and

           Government and Planning, August 2016),



The Queensland Acid Sulfate Soil Technical Manual – Soil Management Guidelines Version 3.8 suggest the
adoption of eight (8) Management Principles associated with ASS which include;
     The disturbance of ASS should be avoided wherever possible;
     Where disturbances of ASS is unavoidable, preferred management strategies are:
               o minimisation of disturbance;
               o neutralisation;
               o hydraulic separation of sulfides either on its own or in conjunction with excivation;
               o strategic reburial (reinterment); and
               o Other management measures may be considered but must not pose unacceptably high
                   risks.
     Works should be performed in accordance with best practice environmental management;
     Any associated waters potentially contaminated by ASS disturbance must be considered in this
         plan;
     Receiving marine, estuarine, brackish or fresh waters are not to be used as a primary means of
         diluting and/or neutralising ASS or associated contaminated waters;
     Management of disturbed ASS is to occur if the ASS action criteria is reached or exceeded;
     Stockpiling of untreated ASS above the permanent groundwater table with (or without) containment
         is not an acceptable long-term management strategy. For example, soils that are to be stockpiled,
         disposed of, used as fill, placed as temporary or permanent cover on land or in waterways, sold or
         exported off the treatment site or used in earth bunds, that exceed the ASS action criteria listed in
         QASSIT Guidelines should be treated/managed; and
     The following issues should be considered when formulating ASS environmental management
         strategies:
         The sensitivity and environmental values of the receiving environment, which includes the
               conservation, protected or other relevant status of the receiving environment;
         Whether groundwaters and/or surface waters are likely to be directly or indirectly affected;
         The heterogeneity, geochemical and textural properties of soils on-site; and
         The management and planning strategies of Local Government and/or State Government,
               including Regional or Catchment Management Plans/Strategies and State and Regional
               Coastal Management Plans.

9.3 ASSESSMENT AND RECOMMENDATIONS
The proposed development is likely to involve excavation and disturbance of greater than 100 but less than
1,000m3 of soils, and the filling of greater than 500m3 of soils at or below 5.0m AHD.

Management and treatment of ASS must be undertaken in accordance with section 9.4 below.
