13.12 According to the environmental audits performed in the reporting
month, the following recommendations were made:
Air Quality Impact
· To regular watering haul road;
· To provide vehicle washing
facilities with high pressure water jet at every discernible or designated vehicle
exit point;
· To maintain the impervious material to entirely cover the stockpile
of dusty materials; and
· To ensure all regulated machines displayed with valid Non-road Mobile Machinery (NRMM) labels.
Construction Noise Impact
· To ensure compressor was operating
with doors closed.
Water Impact
· To review and implement temporary
drainage system;
· To prevent any surface runoff
discharge into Sheung Yuen River, Ma Wat River or public
road;
· To provide sandbags or construct berm to prevent any outflow of
muddy water from site area;
· To ensure all vehicle clear of earth
and mud before leaving site;
· To ensure the drainage facilities would not be clogged with waste or
sediment to avoid overflow;
· To regularly check the condition of desilting materials for
ensuring proper function;
· To regularly maintain and ensure
water treatment facilities proper operation and functioning;
· To divert all the water generated from construction site to
de-silting facilities with sufficient handling capacity before discharge; and
· To avoid or regularly clear the stagnant water in
drip tray;
Waste/Chemical Management
· To dispose of general refuse properly;
· To clear and avoid the oil stain at site area;
· To provide proper storage area for chemical storage; and
· To maintain drip tray for chemical storage well.
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.
Ecology
· Properly erect and maintain 2m high solid barriers for protecting
Siu Hang San Tsuen Stream.
Permit/ Licences
· To display valid Permit or Licences on
site entrance.
