13.11 According
to the environmental audits performed in the reporting month, the following
recommendations were made:
Air
Quality Impact
· To
enhance the dust suppression measures such as water spraying on all haul roads
and exposed work site area;
· To
maintain the impervious material to entirely cover the stockpile of dusty materials;
· To
ensure all regulated machines displayed with valid Non-road Mobile Machinery
(NRMM) labels; and
· To
keep public road near work site area clean and free of dust.
Water Impact
· To
prevent any surface runoff discharge into nearby drainage or stream;
· To
divert all the water generated from construction site to de-silting facilities
with enough handling capacity before discharge;
and
· To
ensure the drainage facilities would not be clogged with waste to avoid
overflow.
Waste/Chemical Management
· To
properly dispose of general refuse on site;
· To
avoid improper handling, storage and disposal of oil drums or chemical
containers on site; and
· To
store chemical waste/waste oil properly in the designated place before
disposal.
Landscape
& Visual Impact
· To
clear the construction materials/wastes properly within the tree protection
zone.
· Retained
trees should be carefully protected.
· Dull green fencing should be secured with no gaps
or no holes.
Landfill
Gas Hazard
· “No Smoking” and “No Naked Flame” notices in
Chinese and English should be posted prominently around the construction site.
Land
Contamination
· Stockpiling site(s) should be lined with
impermeable sheeting and bunded. Stockpiles should be properly covered by
impermeable sheeting to reduce dust emission during dry season or contaminated
run-off during rainy season. Watering should be avoided on stockpiles of soil
to minimize runoff.
