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.
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/
