Good Site
Practices: l
Only well-maintained plant should be operated on-site and plant should
be serviced regularly during the construction program. l
Mobile plant, if any, should be sited as far away from NSRs as
possible. l
Machines and plant (such as trucks) that may be in intermittent use
should be shut down between works periods or should be throttled down to a
minimum. l
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. l
Material stockpiles and other structures should be effectively
utilised, wherever practicable, in screening noise from on-site construction
activities. |

between vessels and the seabed in all tide conditions, to ensure that undue
turbidity is not generated by turbulence from vessel movement or propeller
wash; l
all barges / dredgers should be fitted with tight fitting seals to

construction activities should not cause foam, oil, grease, scum,
litter or other objectionable matter to be present on the water within the

barges or hoppers should not be filled to a level that will cause the

impact predictions are representative, and to ensure that all the recommended
mitigation measures are implemented properly. If the water quality monitoring
data indicate that the proposed dredging works result in unacceptable water
quality impacts in the receiving water, appropriate actions should be taken
to review the dredging operation and additional measures such
as use of frame-type silt curtain, deployment of double silt curtains,
slowing down, or rescheduling of works should be implemented as
necessary. |

screens are recommended to be deployed at six selected WSD flushing water
intakes during the capital dredging. The contractor for capital dredging shall
demonstrate and ensure that the design of the silt screen will not affect the
normal operation of flushing water intake. The contractor shall obtain consensus
from all relevant parties, including WSD and Marine Department on the design
of the silt screen at each of the six selected flushing water intake points
before installation of the silt screen and commencement of the proposed
dredging works. As a mitigation
measure to avoid the pollutant and refuse entrapment problems and to ensure
that the impact monitoring results are representative, regular maintenance of
the silt screens and refuse collection should be performed at the monitoring
stations at regular intervals on a daily basis. The Contractor should be responsible
for keeping the water behind the silt screen free from floating rubbish and
debris during the impact monitoring period. |

Good Site Practices · Nomination of an approved person, such as a
site manager, to be responsible for good site practices, arrangements for
collection and effective disposal to an appropriate facility, of all wastes
generated at the site. · Training of site personnel in proper waste
management and chemical waste handling procedures. · Provision of sufficient waste disposal
points and regular collection for disposal. · Appropriate measures to minimise windblown litter and
dust during transportation of waste by either covering trucks or by
transporting wastes in enclosed containers. · A recording system for the amount of wastes
generated, recycled and disposed of (including the disposal sites). · Segregation and storage of different types of
waste in different containers, skips or stockpiles to enhance reuse or
recycling of materials and their proper disposal. · Encourage collection of aluminium cans, PET
bottles and paper by providing separate labelled bins to enable these wastes
to be segregated from other general refuse generated by the work force. · Any unused chemicals or those with remaining
functional capacity shall be recycled. |

Marine Sediments The dredged
marine sediments would be loaded onto barges and transported to the
designated disposal sites allocated by the MFC depending on their level of
contamination. Sediment
classified as Category L would be suitable for Type 1 - Open Sea
Disposal. Contaminated sediment
would require either Type 1 – Open Sea Disposal (Dedicated Sites) or Type 2 -
Confined Marine Disposal and must be dredged and transported with great care
in accordance with ETWB TCW No.
34/2002. Subject to the final
allocation of the disposal sites by MFC, the dredged contaminated sediment
must be effectively isolated from the environment upon final disposal and
shall be disposed of at the East Sha Chau Contaminated Mud Pits that are

marine sediment to be dredged have been analysed and recorded. According to the ETWB TCW No. 34/2002,
this will involve the submission of a formal Sediment Quality Report to the
DEP, prior to the dredging contract being tendered. The contractor for the dredging works shall
apply for the allocation of marine sediment disposal sites from all relevant authorities. |

Bottom opening of barges shall be fitted with
tight fitting seals to prevent leakage of material. Excess material shall be cleaned from
the decks and exposed fittings of barges and hopper dredgers before the
vessel is moved. ·
Monitoring of the barge loading shall be
conducted to ensure that loss of material does not take place during
transportation. Transport barges
or vessels shall be equipped with automatic self-monitoring devices as
specified by the DEP. ·
Barges or hopper barges shall not be filled to

Construction and Demolition Material It is
recommended that the extent of dredging of the existing seawall should be
kept to a minimum in the detailed design of the new cruise terminal to minimize
generation of C&D material.
Mitigation measures and good site practices should be incorporated in
the contract document to control potential environmental impact from handling
and transportation of C&D material.
The mitigation measures include: ·
Where it is unavoidable to have transient stockpiles of C&D material
within the Project work site pending collection for disposal, the transient
stockpiles shall be located away from waterfront or storm drains as far as
possible. ·
Open stockpiles of construction materials or construction wastes on-site should be
covered with tarpaulin or similar fabric. ·
Skip hoist for material transport should be totally enclosed by impervious sheeting. ·
Every vehicle should be washed to remove any dusty materials from its body and
wheels before leaving a construction site. ·
The area where vehicle washing takes place and the section of the road
between the washing facilities and the exit point should be paved with
concrete, bituminous materials or hardcores. ·
The load of dusty materials carried by vehicle leaving a construction
site should be covered entirely by clean impervious sheeting to ensure dust
materials do not leak from the vehicle. ·
All dusty materials should be sprayed with water prior to any loading,
unloading or transfer operation so as to maintain the dusty materials wet. ·
The height from which excavated materials are dropped should be
controlled to a minimum practical height to limit fugitive dust generation
from unloading. |
