6.12
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 ensure properly maintenance
for de-silting facilities.
·
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.
·
To implement Dolphin Exclusion Zone during the installation of
bored pile casing located in the waters to the west of Airport.
·
To implement Dolphin Watching Plan after the bored piling
casing is installed.
·
To ensure the acoustically-decoupled measures 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
removing off site.
·
To
avoid any discharge or accidental spillage of chemical waste or oil directly from the
site.
·
To
avoid improper handling or storage of oil drum on site.
