Potential impact Desired<br />

Outcome<br />

4.3 Terrestrial Soils<br />

and Geology:<br />

• Earthworks<br />

and soil<br />

compaction<br />

• Increased<br />

erosion and<br />

Minimise soil<br />

loss, reduce<br />

erosion and<br />

decrease, risk<br />

of siltation of<br />

water<br />

resources and<br />

sedimentation risk of<br />

of water contamination<br />

resources<br />

• Potential<br />

contamination<br />

from spills<br />

4.4 Water Resource<br />

impacts:<br />

• Potential<br />

contamination<br />

from<br />

accidental<br />

spills and<br />

increased<br />

erosion and<br />

runoff<br />

• Water use<br />

Description of mitigation<br />

• Minimisation of concentrated transportation and<br />

excavation during decommissioning to reduce erosion;<br />

• Rehabilitation and revegetation of the site following<br />

demolition and levelling before the next wet season;<br />

• Update and implement waste management plan, to be<br />

updated as part of the Site Closure and Restoration Plan.<br />

• Store hydrocarbons, fuels, lubricants and chemicals in<br />

bunded and lockable oil storage containers, with hoses<br />

and gauges kept within the bund.<br />

• Regular checking and maintenance of all plant and<br />

machinery to minimise the risk of fuel or lubricant<br />

leakages;<br />

• Training of relevant staff in safe storage and handling<br />

practices, and rapid spill response and cleanup<br />

techniques;<br />

• Minimise stockpiling, 10 m buffer zone between drainage<br />

channels and stockpiles (leaving existing vegetation in<br />

place and shield stockpiles using geotextiles if necessary;<br />

• Correct and timeous waste separation, storage and<br />

disposal of demolition waste and chemicals (including<br />

transformer oil, residual sludge from the wastewater<br />

treatment works and diesel) and/ or incidents and spills<br />

at licensed waste disposal facility; and<br />

• Decommission or cap (if to remain in use) the<br />

groundwater abstraction borehole(s) to prevent the<br />

development of a potential pathway for contaminants.<br />
