ATTACHMENT E - REVISED NOISE AND DUST MANAGMENT PLAN
ITEM 11.1 COUNCIL 24/04/2013
Sand Extraction – Lot 75, Haag Road, Yelverton
3.5.2 Dust Screens
Screening along the boundary of the site can be used as a barrier against dust leaving the site. Screening
can occur in the form of vegetation screens, mesh fencing or stabilised stockpiles along the boundary.
As a contingency, 3m high screens of suitable textile weave material, may be erected after taking into
account the distance of current operations to the boundaries, the level of activity at the boundary and
distance to neighbours and public roads.
3.5.3 Soil Stabilisation
Dust generation on soils that have been exposed or disturbed (e.g. stockpiles, open areas) will be
stabilised through the use of various surface treatments. Adequate stabilisation using these treatments
is dependent on many factors, including soil type, level of activity in area, and location of area. The
method of surface treatment will be determined by the site supervisor on a case by case basis.
Table 3-1 lists some of the major treatments to be used for soil stabilisation along with suitability and
management requirements. These treatments require re-application over time as their effectiveness
decreases due to general wear. Restricting access to treated areas will prolong the longevity of the
treatment.
Table 3-1 Surface Treatments for Soil Stabilisation
Treatment Suitability Management
Mulch Areas where no traffic is required
(e.g. disturbed areas not in use, pit
walls)
Suitable as a short term
stabilisation agent prior to longer
term stabilisation being applied
Chemical
Stabilisation
Areas with little or moderate
traffic (e.g. site entry roads, light
vehicle tracks, laydown areas)
Vegetative Cover Non-trafficked areas where no
more disturbance will occur (e.g.
stockpiles)
Only suitable on soils that can
support vegetation
Restrict access to areas
once applied
Inspect area to determine
when re-application is
required
Apply and manage as per
manufacturers
specifications
Seed in winter to ensure
growth
Areas must be stabilised
using other techniques
until growth is adequate
Restrict access once
growth is established
Stabilisation with
gravel or similar
material
Suitable for highly trafficked areas
(e.g. haul roads)
Maintain formation of
surface with graders etc
Use in conjunction with
water application or
chemical stabilisation
The maximum height for overburden mounds and stockpiles will be limited to ≤3m, unless appropriately
stabilised with soil binding agent, while the maximum height of topsoil mounds and stockpiles will be
limited to ≤2m high.
