Project Planning and Refinement

Throughout the Project planning conceptual phase and during the development of the EIS document the primary objective was to develop a conceptual mine plan that minimised potential environmental and social impacts whilst maximising resource recovery and operational efficiency.

The conceptual mine plan incorporated the following management and mitigation measures to further reduce the impact on the environment and society:

  •       No disturbance to the alluvial black soil Liverpool Plains;

  •       The protection of the groundwater regime of the alluvial black soil Liverpool Plains with a
          minimum 900 m horizontal barrier of natural material between active mining areas and
          the highly productive Gunnedah Formation aquifer;

  •       A minimum 150 m buffer from the alluvial black soil Liverpool plains to the active mining area;

  •       Disturbance of land owned by Shenhua Watermark;

  •       No disturbance of Mt Watermark;

  •       No disturbance of the Breeza State Forest;

  •       Only one final void which is the farthest distant from the black soil Liverpool plains and
          Gunnedah Formation;

  •       The Overburden Emplacement Area merges into the natural topography (such as Mt
          Watermark and Black Mountain);

  •       Reduced slopes ( of approximately 10 degrees or less )of the Overburden Emplacement Area
          to facilitate the re-establishment of Box Gum Woodland on the mine rehabilitation and to
          achieve the maximum post-mining land capability classification practicable;

  •       Reconfiguration of the Eastern Mining Area Overburden Emplacement Area to avoid 143 ha of
          Critically Endangered Ecological Communities Box Gum Woodland;

  •       Avoidance of four Aboriginal archaeological sites of high, moderate and low significance
          within the Eastern Mining Area;

  •       Early and progressive rehabilitation of the exposed Overburden Emplacement Areas will
          reduce the generation of dust. Haul routes have been designed to reduce the exposure
          in elevated areas and to reduce haul distance;

  •       Utilising larger equipment to reduce the number of mobile fleet units operating at any one
          time;

  •       Implementation of best-practice sound power levels and operational efficiency on all of
          the large mobile fleet equipment to reduce air and noise impacts;

  •       The Coal Handling Processing Plant area and associated feed conveyors will be designed
          and clad to reduce air and noise impacts;

  •       Rail loop will be designed with the minimum grade to reduce locomotive power and noise
          levels whilst loading;

  •       A rehabilitation strategy to reinstate approximately 3,233 ha of Class III rural land capability,
          of which approximately 1,000 ha is to be used for agricultural purposes;

  •       Situating the Mine Infrastructure Area to avoid Critically Endangered Ecological
          Communities whilst affording maximum natural shielding from neighbouring properties; and

  •       The development and implementation of a Biodiversity Offset Strategy to compensate for
          any ecological impacts.
