13.13 According to the
environmental audits performed in the reporting month, the following
recommendations were made:
Air Quality Impact
¡P To regular water haul roads;
¡P To provide vehicle washing facilities with high pressure water jet at
every discernible or designated vehicle exit point;
¡P To maintain the impervious
material to entirely cover the stockpile of dusty materials; and
¡P To ensure all regulated
machines displayed with valid Non-road Mobile Machinery (NRMM) labels.
Construction Noise Impact
¡P To ensure compressor operated with doors closed.
¡P To ensure the noise barriers were
fully enclosed.
Water Impact
¡P To review and implement temporary drainage system;
¡P To prevent any surface runoff discharge into Sheung Yuen River, Ma Wat
River or public road;
¡P To provide sandbags or
construct berm to prevent any outflow of muddy water from site area;
¡P To ensure all vehicle clear of earth and mud before leaving the site areas;
¡P To ensure the drainage
facilities would not be clogged with waste or sediment to avoid overflow;
¡P To regularly check the
condition of desilting materials for proper function;
¡P To regularly maintain and ensure water treatment facilities proper
operation and function;
¡P To divert all the water
generated from the construction site to
de-silting facilities with sufficient handling capacity before discharge; and
¡P
To avoid
or regularly clear the stagnant water in drip trays;
Waste/Chemical Management
¡P To dispose of general refuse
properly;
¡P To clear and avoid oil stains at site areas;
¡P To provide proper storage
areas for chemical; and
¡P
To
maintain drip trays for chemical storage well.
Landfill Gas Hazard
¡P ¡§No Smoking¡¨ and ¡§No Naked Flame¡¨ notices
in Chinese and English should be posted prominently around the construction
site.
Land Contamination
¡P 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
¡P
Properly
erect and maintain 2m high solid barriers for protecting Siu Hang San Tsuen
Stream.
Permit/ Licences
¡P To display valid Permit or
Licences at the site entrances.
