Works to be taken for the
coming monitoring period are described as follows:
i.
finishing works for booster
pump house;
ii.
laying friction course and road
marking work;
iii.
drainage work;
iv.
landscaping and establishment
work at ground level; and
v.
TCSS and lighting cabling works
10.1.2
Potential environmental impacts
arising from the above construction activities are mainly associated with dust,
noise, site run-off and waste. However,
with the implementation of the following mitigation measures, potential impacts
to the surrounding sensitive receivers could be minimized.
10.1.3
Construction Dust
i.
frequently watering of haul
road and unpaved areas;
ii.
prohibition of any open burning
on site;
iii.
investigation of other dust
sources near air sensitive receivers;
iv.
regularly watering or covering
of open areas and stockpiles with tarpaulin sheeting;
v.
hydroseeding or covering
inactive exposed soil areas with impervious sheeting if necessary;
vi.
switching off vehicles and
equipment while not in use; and
vii.
regular maintenance of onsite
machineries and vehicles.
10.1.4
Construction Noise
i.
identification of noise sources
arising within and outside work site; and
ii.
follow-up of any exceedance
caused by the construction works.
10.1.5
Construction Run-off
i.
identification of sources of
run-off from site;
ii.
provision of
sandbags/bunds/surface channels to direct run-off to silt/sand removal
facilities;
iii.
avoidance of direct discharge of
construction wastewater into storm water drainage;
iv.
provision of adequate treatment
of construction wastewater and run-off prior to discharge; and
v.
covering of exposed slope with
tarpaulin or similar means during rainstorm.
10.1.6
Construction Waste Management
i.
avoidance of accumulation of
construction waste materials and/or general refuse on site;
