Description of mitigation
• Use most effective mufflers, enclosures and low-noise tool
bits and blades;
• Investigate use of alternatives to audible reversing alarms
(such as broadband noise emitting models) or configure to
maximise forward movements of mobile plant;
• Use alternatives to diesel/petrol engines and pneumatic
units, such as hydraulic or electric-controlled units, where
feasible and reasonable;
• Use temporary noise barriers for small equipment, where
required;
• Reduce throttle settings and turn off equipment and plant
when not used; and
• Regular inspection and maintenance of all plant and
equipment; and
• Perform ongoing monitoring of noise levels at the four
farm receptors (see Chapter 9) and submit results to
FMEnv.

• Effective site drainage including cut-off drains to divert
surface runoff from exposed soils or construction areas;
• Construct temporary drainage channels to channel and
divert surface water away from any down slope land and
agricultural plots;
• Install oil/ water separators and silt traps before effluent
leaves the site;
• Implement low impact excavation, in-fill and trenching
methods;
• Minimise bare ground and stockpiles to avoid silt runoff;
• Rehabilitate and revegetate cleared areas before the next
wet season;
• Bunding of areas where hazardous substances are stored
(eg fuel, waste areas); and
• Develop and implement of a waste management plan (as
part of the ESMP).
