According
to the environmental audit performed in the reporting month, the following recommendations
were made:
Air Quality Impact
·
To
regularly maintain the quality of machinery and vehicles on site.
·
To
implement dust suppression measures on all haul roads, stockpiles, dry surfaces
and excavation works.
·
To
provide hoarding along the entire length of that portion of the site boundary.
Noise Impact
·
To
inspect the noise sources inside the site.
·
To
space out noisy equipment and position the equipment as far away as possible
from sensitive receivers.
·
To
provide temporary noise barriers for operations of noisy equipment near the
noise sensitive receivers, if necessary.
Water Impact
·
To
prevent any surface runoff discharge into any stream course and
sea.
·
To
review and implement temporary drainage system.
·
To
identify any wastewater discharges from site.
·

To
clear the silt and sediment in the sedimentation tanks.
·
To
review the capacity of de-silting facilities for discharge.
·
To
divert all the water generated from construction site to de-silting facilities
with enough handling capacity before discharge.
·
To
avoid accumulation of stagnant
and ponding water
on site.
Ecology Impact
·
To implement Spill Response Plan in the event of
accidential spillage of or other hazardours chemicals.
·

were implemented for air compressors and other noisy equipment mounted on
construction vessels according to acoustic decoupling measures plan.
Waste/Chemical Management
·
To
check for any accumulation of waste materials or rubbish on site.
·
To ensure the performance of sorting of C&D
materials at source (during generation);
·
To carry out inspection of dump truck at site exit
to ensure inert and non-inert C&D materials are properly segregated before
