Pollution Control (Construction Dust) Regulation & Good Site Practices ·
Use of regular watering, with complete coverage, to reduce dust
emissions from exposed site surfaces and unpaved roads, particularly during
dry weather. ·
Use of frequent watering for particularly dusty construction areas and
areas close to ASRs. ·
Side enclosure and covering of any aggregate or dusty material storage
piles to reduce emissions. Where
this is not practicable owing to frequent usage, watering should be applied
to aggregate fines. ·
Open stockpiles should be avoided or covered. Where possible, prevent placing dusty
material storage piles near ASRs. ·
Tarpaulin covering of all dusty vehicle loads transported to, from and
between site locations. ·
Establishment and use of vehicle wheel and body washing facilities at
the exit points of the site. ·
Provision of wind shield and dust extraction units or similar dust
mitigation measures at the loading points, and use of water sprinklers at the
loading area where dust generation is likely during the loading process of
loose material, particularly in dry seasons/ periods. ·
Imposition of speed controls for vehicles on unpaved site roads. 8 kilometers per hour is the
recommended limit. ·
Where possible, routing of vehicles and positioning of construction
plant should be at the maximum possible distance from ASRs. ·
Every stock of more than 20 bags of cement or dry pulverised fuel ash
(PFA) should be covered entirely by impervious sheeting or placed in an area
sheltered on the top and the 3 sides. ·
Cement or dry PFA delivered in bulk should be stored in a closed silo
fitted with an audible high level alarm which is interlocked with the
material filling line and no overfilling is allowed. ·
Loading, unloading, transfer, handling or storage of bulk cement or
dry PFA should be carried out in a totally enclosed system or facility, and
any vent or exhaust should be fitted with an effective fabric filter or
equivalent air pollution control system |

To minimize the potential water quality impacts from
the nullah reconstruction works, the practices outlined below should be
adopted where applicable: Ÿ The proposed works should
be carried out within the dry season between October and March when the flow
in the open nullah is low. Ÿ The use of less or
smaller construction plants may be specified to reduce the disturbance to the
nullah bed. Ÿ Temporary storage
of materials (e.g. equipment, filling materials, chemicals and fuel) and
temporary stockpile of construction materials should be located well away
from the nullah and any water courses during carrying out of the construction
works. Ÿ Stockpiling of
construction materials and dusty materials should be covered and located away
from the nullah any water courses. Ÿ Construction
debris and spoil should be covered up and/or disposed of as soon as possible
to avoid being washed into the nullah and nearby water receivers. Ÿ Construction
activities, which generate large amount of wastewater, should be carried out
in a distance away from the nullah, where practicable. Ÿ Construction
effluent, site run-off and sewage should be properly collected and/or
treated. Ÿ Any works site
inside the nullah should be temporarily isolated,
such as by placing of sandbags or silt curtains with lead edge at bottom and
properly supported props to prevent adverse impact on the water quality. Ÿ Proper shoring may
need to be erected in order to prevent soil/mud from slipping into the nullah
and nearby watercourse. Ÿ Supervisory staff
should be assigned to station on site to closely supervise and monitor the
works. |

The incident report should provide sufficient
details for the evaluation of any environmental impacts due to the spillage
and assessment of the effectiveness of measures taken. ·
In case any spillage or accidents results in
significant land contamination, EPD should be informed immediately and the
Project operator should be responsible for the cleanup of the affected
area. The responses procedures described in Sections 6.65-6.66 of the
EIA Report should be followed accordingly together with the land
contamination assessment and remediation guidelines stipulated in the Guidance Manual for Use of Risk-based
Remediation Goals for Contaminated Land Management and the Guidance Note for Contaminated Land
Assessment and Remediation. |

Good Site Practice: ·
Only
well-maintained plant should be operated on-site and plant should be serviced
regularly during the construction program; ·
Mobile plant,
if any, should be sited as far from noise sensitive receivers (NSRs) as
possible; ·
Machines and
plant (such as trucks) that may be in intermittent use should be shut down
between work periods or should be throttled down to a minimum; ·
Plant known
to emit noise strongly in one direction should, wherever possible, be
orientated so that the noise is directed away from the nearby NSRs; and ·
Material
stockpiles and other structures should be effectively utilized, wherever
practicable, in screening noise from on-site construction activities. |
