13.14 According to the environmental audits performed in the reporting
month, the following recommendations were made:
Air
Quality Impact
· To regular water haul roads;
· 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 operated
with doors closed.
· To ensure the noise barriers were fully enclosed.
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 the site areas;
· 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 proper
function;
· To regularly maintain and ensure
water treatment facilities proper operation and function;
· To divert all the water generated from the construction site to de-silting facilities with sufficient handling
capacity before discharge; and
· To avoid or regularly clear the stagnant water in
drip trays;
Waste/Chemical
Management
· To dispose of general refuse properly;
· To clear and avoid oil stains at site areas;
· To provide proper storage areas for chemical; and
· To maintain drip trays 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 minimise 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 at the site entrances.
