Barging
Facility: ·
Unloading of spoils to barge – the unloading process
should be undertaken within a 3-sided screen with top tipping hall. Water spraying and flexible dust curtains
should be provided at the discharge point for dust suppression. ·
Transportation of
the spoil from the construction sites to the Barging Point – watering once
along all paved haul roads for every working hour to
reduce dust emission by 91.7%. This dust suppression efficiency
is derived based on the average haul road traffic, average evaporation rate
and an assumed application intensity of 1.7 L/m2 once every
working hour. Any potential dust
impact and watering mitigation would be subject to the actual site
condition. For example, a construction
activity that produces inherently wet conditions or in cases under rainy
weather, the above water application intensity may not be unreservedly
applied. While the above watering
frequency is to be followed, the extent of watering may vary depending on actual
site conditions but should be sufficient to maintain an equivalent intensity
of no less than 1.7L/m2 to achieve the removal efficiency. The dust levels would be monitored and
managed under an EM&A programme as specified in
the EM&A Manual. ·

well-maintained plant should be operated on-site and plant should be serviced
regularly during the construction program. Ÿ Silencers
or mufflers on construction equipment should be utilized and should be
properly maintained during the construction program. Ÿ Mobile

Construction
site run-off and general construction activities: Ÿ Surface
run-off from construction sites should be discharged into storm drains via
adequately designed sand/silt removal facilities such as sand traps, silt
traps and sedimentation basins.
Channels or earth bunds or sand bag barriers should be provided on
site to properly direct stormwater to such silt removal facilities. Perimeter channels at site boundaries
should be provided on site boundaries where necessary to intercept storm
run-off from outside the site so that it will not wash across the site. Catchpits and
perimeter channels should be constructed in advance of site formation works
and earthworks. Ÿ Silt
removal facilities, channels and manholes should be maintained and the
deposited silt and grit should be removed regularly, at the onset of and
after each rainstorm to prevent local flooding. Any practical options for the diversion and
re-alignment of drainage should comply with both engineering and environmental
requirements in order to provide adequate hydraulic capacity of all drains.
Minimum distances of 100 m should be maintained between the discharge points
of construction site run-off and the existing saltwater intakes. Ÿ Construction
works should be programmed to minimize soil excavation works in rainy seasons
(April to September). If excavation in
soil cannot be avoided in these months or at any time of year when rainstorms
are likely, for the purpose of preventing soil erosion, temporary exposed
slope surfaces should be covered e.g. by tarpaulin, and temporary access
roads should be protected by crushed stone or gravel, as excavation
proceeds. Intercepting channels should
be provided (e.g. along the crest / edge of excavation) to prevent storm
run-off from washing across exposed soil surfaces. Arrangements should always be in place in
such a way that adequate surface protection measures can be safely carried
out well before the arrival of a rainstorm. Ÿ Earthworks
final surfaces should be well compacted and the subsequent permanent work or
surface protection should be carried out immediately after the final surfaces
are formed to prevent erosion caused by rainstorms. Appropriate drainage like intercepting
channels should be provided where necessary. Ÿ Measures
should be taken to minimize the ingress of rainwater into trenches. If
excavation of trenches in wet seasons is necessary, they should be dug and
backfilled in short sections.
Rainwater pumped out from trenches or foundation excavations should be
discharged into storm drains via silt removal facilities. Ÿ Open
stockpiles of construction materials (e.g. aggregates, sand and fill
material) on sites should be covered with tarpaulin or similar fabric during
rainstorms. Ÿ Manholes
(including newly constructed ones) should always be adequately covered and
temporarily sealed so as to prevent silt, construction materials or debris
from getting into the drainage system, and to prevent storm run-off from
getting into foul sewers. Discharge of
surface run-off into foul sewers must always be prevented in order not to
unduly overload the foul sewerage system. |

Regulation should be observed and complied with for control of chemical
wastes. Ÿ Any
service shop and maintenance facilities should be located on hard standings
within a bunded area, and sumps and oil

involving activities with potential for leakage and spillage should only be
undertaken within the areas appropriately equipped to control these

Hydrogeological Impact: Ÿ
For the construction works for the tunnel, station and
ventilation shafts, which
will require dewatering temporarily during their construction, the following
measures should be put in place in order to mitigate any drawdown effects to
the groundwater table during the operation of the temporary dewatering works: - Toe
grouting should be applied beneath the toe level of the temporary/permanent
cofferdam walls as necessary to lengthen the effective flow path of
groundwater from outside and thus control the amount of water inflow to the
excavation. - Recharge
wells should be installed as necessary outside the excavation areas. Water pumped from the excavation areas
should be recharge back into the ground. Ÿ In
addition, the Contractor should initially adopt suitable water control
strategies as far as practicable while undertaking the excavation works. The
water control strategies are given as follow: - Probing
Ahead: The Contractor will undertake rigorous probing of the ground ahead of
tunnel excavation works to identify zones of significant water inflow. The
probe drilling results will be evaluated to determine specific grouting
requirements in line with the tunnel advance. In such zones of significant
water inflow that could occur as a result of discrete, permeable features,
the intent would be to reduce overall inflow by means of cut-off grouting
executed ahead of the tunnel advance. - Pre-grouting:
Where water inflow quantities are excessive, pre-grouting will be required to
reduce the water inflow into the tunnel. The pre-grouting will be achieved
via a systematic and carefully specified protocol of grouting. - In
principle, the grout pre-treatment would be designed on the basis of probe
hole drilling ahead of the tunnel face. - Post-grouting:
Groundwater drawdown will be most likely due to inflows of water into the
tunnel that have not been sufficiently controlled by the pre-grouting
measures. Where this occurs post grouting will be undertaken before the

Ÿ Mitigation
measures for minimizing water quality impacts from construction site runoff
and general construction activities should be applied. Other good site
practices include: - All
vessels should be sized so that adequate clearance is maintained 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. - All
hopper barges should be fitted with tight fitting seals to their bottom
openings to prevent leakage of material. - Construction
activities should not cause foam, oil, grease, scum, litter or other
objectionable matter to be present on the water within the site. - Loading
of barges and hoppers should be controlled to prevent splashing of material
into the surrounding water. Barges or
hoppers should not be filled to a level that will cause the overflow of
materials or polluted water during loading or transportation. |

Sediments:
Ÿ The basic
requirements and procedures for excavated sediment disposal specified under
ETWB TC(W) No. 34/2002 shall be followed. Ÿ The Project
Proponent should agree in advance with MFC of CEDD on the site allocation.
Subject to the final decision by MFC, Type 1 sediments are typically disposed
to South Cheung Chau and/or East of Ninepin as open sea disposal while Type 2
sediments are disposed to East Sha Chau as confined
marine disposal. Ÿ Sampling and
Testing Plan(s) should be prepared in accordance with ETWB
TC(W) No. 34/2002. Site investigation, based on the
Sediment Sampling and Testing Plan(s), should be carried out in order to
confirm the disposal arrangements for the proposed excavated sediments. A
Sediment Quality Report (SQR) should then be submitted to EPD for agreement
prior to the tendering of the construction contract, discussing in details
the site investigation, testing results as well as the delineation of each of
the categories of excavated materials and the corresponding types of
disposal. Ÿ The
excavated sediments is expected to be loaded onto the dumping trucks and
transferred to the barging point where the sediments would be transported via
barge to the existing designated disposal sites allocated by the MFC. The
excavated sediment would be disposed of according to its determined disposal
options and ETWB TC(W) No. 34/2002. Ÿ Requirements
of the Air Pollution Ordinance (Construction Dust) Regulation, where
relevant, shall be adhered to during excavation, transportation and disposal
of sediments. Ÿ Stockpiling
of contaminated sediments should be avoided as far as possible. If temporary stockpiling of contaminated
sediments is necessary, the excavated sediment should be covered by tarpaulin
and the area should be placed within earth bunds or sand bags to prevent leachate from entering the ground, nearby drains and/or
surrounding water bodies. The
stockpiling areas should be completely paved or covered by linings in order
to avoid contamination to underlying soil or groundwater. Separate and clearly defined areas should
be provided for stockpiling of contaminated and uncontaminated
materials. Leachate,
if any, should be collected and discharged according to the Water Pollution
Control Ordinance (WPCO). Ÿ In order
to minimize the potential odour / dust emissions during excavation and
transportation of the sediment, the excavated sediments should be wetted
during excavation / material handling and should be properly covered when
placed on trucks or barges. Loading of
the excavated sediment to the barge should be controlled to avoid splashing
and overflowing of the sediment slurry to the surrounding water. Ÿ The
barge transporting the sediments to the designated disposal sites should be
equipped with tight fitting seals to prevent leakage and should not be filled
to a level that would cause overflow of materials or laden water during
loading or transportation. Ÿ In
order to minimize the exposure to contaminated materials, workers should,
when necessary, wear appropriate personal
protective equipments (PPE) when handling contaminated sediments. Adequate washing and cleaning facilities
should also be provided on site. |

work is adequate and has been carried out in accordance with the endorsed CAR
and RAP. Information such as soil treatment/disposal records (including trip
tickets), confirmatory sampling results and photographs should be included in
the RR. No construction work should be carried out prior to endorsement of
the RR by EPD. Ÿ In
order to minimise environmental impacts arising
from the handling of potentially contaminated materials, the following
environmental precautionary measures are recommended to be utilised during the course of any required site
remediation: - Excavation
profiles must be properly designed and executed with attention to the
relevant requirements for environment, health and safety; - Excavation
should be carried out during dry season as far as possible to minimise
contaminated runoff from contaminated soils; - Supply
of suitable clean backfill material is needed after excavation; - If
proposed remediation methods employ chemical oxidation methods as the
contaminant mass reduction technology, chemicals will be securely and
separately stored away from sources of ignition or oxidisable
items. Handling will be undertaken by
personnel with appropriate training and Personal Protective Equipment; - Vehicles
containing any excavated materials should be suitably covered to limit
potential dust emissions or contaminated wastewater run-off, and truck bodies
and tailgates should be sealed to prevent any discharge during transport or
during wet conditions; - Speed
control for the trucks carrying contaminated materials should be enforced; - Vehicle
wheel and body washing facilities at the site’s exit points should be
established and used; and - Pollution
control measures for air emissions e.g. from biopile
blower, noise emissions e.g. from blower, and water discharges e.g. runoff
control should be implemented and complied with relevant regulations and
guidelines.” |
