West Ridge Quarry
Site Based Management Plan


      -      straw or organic mulch may be spread over the soil to minimise potential soil erosion until the area is
             revegetated.
      If erosion occurs on treated surfaces, the area is to be re-topsoiled and sown with cover grass.


Species Selection
      Pasture grasses already located within the area shall be the preferred selected species for initial stabilisation of
      rehabilitated landform area(s).


Revegetation
      Methods: There are a range of methods for establishing vegetation including natural regeneration, hydro-mulching,
      seed broadcasting, seedling planting and direct seeding. Seed broadcasting of pasture grasses shall be the preferred
      method of establishing vegetation.
      Ground Preparation: If the area has become compacted, the area is to be ripped prior to seeding.
      Fertilisation: Slow release fertilizer shall be spread over the area being revegetated at a rate prescribed by the
      supplier.
      Watering: Direct seeding is best carried out prior to good rainfall or following soaking rain. Following seeding the area
      should be watered as required to ensure soil moisture is retained during grass establishment. The water quality
      should be tested to ensure pH is between 6.5 and 8.5 and total soluble salts concentration is less than 1000 mg/L.
      Staging: The staging of the rehabilitation works will follow the sequence of quarry development as terminal batters
      are reached. The timing of which will also depend on market and general economic conditions.


Weed and Pest Control
      Any materials (particularly such as earth, soil, mulch and straw) brought onto the Site for rehabilitation shall be
      inspected to ensure the materials are free from weeds and pests.
      Prior to the establishment of vegetation a spraying campaign may be required to control weeds to prevent migration of
      weed species into areas under rehabilitation.
      Alternative methods for controlling both grass and weeds include manual weeding, burning, slashing, weed matting
      and mulching.
      Predation (e.g. grazing animals, birds, kangaroos, hares, and insects) are risks for revegetation. Depending on the
      situation, specific measures may be required to protect the works from predation.


Demobilisation
      All temporary infrastructure and materials (including flagging tape and survey pegs) associated with the operation are
      to be removed.
      Any sumps or other temporary installations are to be backfilled, unless they have been incorporated within the final
      land use rehabilitation plan.
      All wastes are to be removed and disposed of appropriately either to licensed landfill or disposal/recycling facility.
      Any hydrocarbon contaminated soil is to be remediated.
      Landscape and batter depressed areas (e.g. borrow pits) to blend in with surrounding landform.
      Batter angles shall be such that slopes are stable, safe and will not exacerbate erosion issues.
      Disused compacted surfaces will be ripped to a depth of approximately 300mm, along contour lines where ground
      conditions and hydrology allow.
