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

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.
