¡P
To
implement dust suppression measures on all haul roads, stockpiles, dry surfaces
and excavation works.
¡P
To
provide hoarding along the entire length of that portion of the site boundary.
Noise Impact
¡P
To
inspect the noise sources inside the site.
¡P
To
space out noisy equipment and position the equipment as far away as possible
from sensitive receivers.
¡P
To
provide temporary noise barriers for operations of noisy equipment near the
noise sensitive receivers, if necessary.
Water Impact

prevent any surface runoff discharge into any stream course and
sea.
¡P
To
review and implement temporary drainage system.
¡P
To
identify any wastewater discharges from site.
¡P

To
clear the silt and sediment in the sedimentation tanks.
¡P
To
review the capacity of de-silting facilities for discharge.
¡P
To
divert all the water generated from construction site to de-silting facilities
with enough handling capacity before discharge.
¡P
To
avoid accumulation of stagnant
and ponding water
on site.
Ecology Impact
