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.
