Dust control practices as stipulated in the
Air Pollution Control (Construction Dust) Regulation should be adopted. These
practices include: Good Site Management § Good site management is important to help
reducing potential air quality impact down to an acceptable level. As a
general guide, the Contractor should maintain high standard of housekeeping
to prevent emission of fugitive dust. Loading, unloading, handling and
storage of raw materials, wastes or by-products should be carried out in a
manner so as to minimise the release of visible dust emission. Any piles of
materials accumulated on or around the work areas should be cleaned up
regularly. Cleaning, repair and maintenance of all plant facilities within
the work areas should be carried out in a manner minimising generation of
fugitive dust emissions. The material should be handled properly to prevent
fugitive dust emission before cleaning. Disturbed Parts of the Roads § Each and every main temporary access should
be paved with concrete, bituminous hardcore
materials or metal plates and kept clear of dusty materials; or § Unpaved parts of the road should be sprayed
with water or a dust suppression chemical so as to keep the entire road
surface wet. Exposed Earth § Exposed earth should be properly treated by
compaction, hydroseeding, vegetation planting or
seating with latex, vinyl, bitumen within six months after the last
construction activity on the site or part of the site where the exposed earth
lies. Loading, Unloading or Transfer of Dusty
Materials § All dusty materials should be sprayed with
water immediately prior to any loading or transfer operation so as to keep
the dusty material wet. Debris Handling § Any debris should be covered entirely by
impervious sheeting or stored in a debris collection area sheltered on the
top and the three sides. § Before debris is dumped into a chute, water
should be sprayed so that it remains wet when it is dumped. Transport of Dusty Materials § Vehicle used for transporting dusty
materials/spoils should be covered with tarpaulin or similar material. The
cover should extend over the edges of the sides and tailboards. Wheel washing § Vehicle wheel washing facilities should be
provided at each construction site exit. Immediately before leaving the
construction site, every vehicle should be washed to remove any dusty
materials from its body and wheels. Use of vehicles § The speed of the trucks within the site
should be controlled to about 10km/hour in order to reduce adverse dust
impacts and secure the safe movement around the site. § Immediately before leaving the construction
site, every vehicle should be washed to remove any dusty materials from its
body and wheels. § Where a vehicle leaving the construction
site is carrying a load of dusty materials, the load should be covered
entirely by clean impervious sheeting to ensure that the dusty materials do
not leak from the vehicle. Site hoarding §
Where a
site boundary adjoins a road, street, service lane or other area accessible
to the public, hoarding of not less than 2.4m high from ground level should
be provided along the entire length of that portion of the site boundary
except for a site entrance or exit. |

sedimentation control facilities. Channels, earth bunds or sand bag barriers
should be provided on site to direct storm water to silt removal facilities.
The design of the temporary on-site drainage system should be undertaken by
the Contractors prior to the commencement of construction (for works areas
located on the existing Airport island) or as soon as the new land is
completed (for works areas located on the new landform); § Sand/silt removal facilities such as
sand/silt traps and sediment basins should be provided to remove sand/silt
particles from runoff to meet the requirements of the TM-DSS standards under
the WPCO. The design of efficient silt removal facilities should make
reference to the guidelines in Appendix A1 of ProPECC
Note PN 1/94. Sizes may vary depending
upon the flow rate. The detailed design of the sand/silt traps should be
undertaken by the Contractors prior to the commencement of construction; § All drainage facilities and erosion and sediment
control structures should be regularly inspected and maintained to ensure
proper and efficient operation at all times and particularly during
rainstorms. Deposited silt and grit should be regularly removed, at the onset
of and after each rainstorm to ensure that these facilities are functioning
properly; § Measures should be taken to minimize the
ingress of site drainage into excavations. If excavation of trenches in wet
periods is necessary, they should be dug and backfilled in short sections
wherever practicable. Water pumped out from foundation excavations should be
discharged into storm drains via silt removal facilities; § In the event that contaminated groundwater
is identified at excavation areas, this should be treated on-site using a
suitable wastewater treatment process. The effluent should be treated
according to the requirements of the TM-DSS standards under the WPCO prior to
discharge to foul sewers or collected for proper disposal off-site. No direct
discharge of contaminated groundwater is permitted; § All vehicles and plant should be cleaned
before leaving a construction site to ensure no earth, mud, debris and the
like is deposited by them on roads. An adequately designed and sited wheel
washing facility should be provided at construction site exits. Wash-water
should have sand and silt settled out and removed regularly to ensure the
continued efficiency of the process. The section of access road leading to,
and exiting from, the wheel-wash bay to the public road should be paved with
sufficient backfall toward the wheel-wash bay to
prevent vehicle tracking of soil and silty water to
public roads and drains. All washwater should be
treated according to the requirements of the TM-DSS standards under the WPCO
prior to discharge; § Open stockpiles of construction materials or
construction wastes on-site should be covered with tarpaulin or similar
fabric during rainstorms. Measures should be taken to prevent the
construction materials, soil, silt or debris from washing away into the
drainage system; § Manholes (including newly constructed ones)
should be adequately covered and temporarily sealed so as to prevent silt,
construction materials or debris being washed into the drainage system and to
prevent stormwater runoff being directed into foul
sewers; and § Precautionary measures should be taken at any time of the year when rainstorms are likely. Actions to be taken when a rainstorm is imminent or forecasted are summarized in Appendix A2 of ProPECC Note PN 1/94. This includes actions to be taken during and/or after rainstorms. Particular attention should be paid to the control of silty surface runoff during storm events. |

Opportunities to minimise waste generation
and maximise the reuse of waste materials generated by the project have been incorporated
where possible into the planning, design and construction stages, and the
following measures have been recommended: § The relevant construction methods
(particularly for the tunnel works) and construction programme have been
carefully planned and developed to minimise the extent of excavation and to
maximise the on-site reuse of inert C&D materials generated by the
project as far as practicable.
Temporary stockpiling areas will also be provided to facilitate
on-site reuse of inert C&D materials.
§ Priority should be given to collect and
reuse suitable inert C&D materials generated from other concurrent
projects and the Governments PFRF as fill materials for the proposed land
formation works. § Only non-dredged ground improvement methods
should be adopted in order to completely avoid the need for dredging and
disposal of marine sediment for the proposed land formation work. § Excavation work for constructing the APM
tunnels, BHS tunnels and airside tunnels will not be down to the CMPs beneath
the fill materials in order to avoid excavating any sediments. § For the marine sediments expected to be
excavated from the piling works of TRC, APM & BHS tunnels, airside
tunnels and other facilities on the proposed land formation area, piling work
of marine sections of the approach lights and HKIAAA beacons, basement works
for some of T2 expansion area and excavation works for the proposed APM depot
should be treated and reused on-site as backfilling materials, although
required treatment level / detail and the specific re-use mode are under
development. |

The following good site practices should be performed during the construction activities include: § 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 by
tarpaulin/ similar material or by transporting wastes in enclosed containers.
The cover should be extended over the edges of the sides and tailboards. § Stockpiles of C&D materials should be
kept wet or covered by impervious sheets to avoid wind-blown dust. § All dusty materials including C&D
materials should be sprayed with water immediately prior to any loading
transfer operation so as to keep the dusty material wet during material
handling at the barging points/ stockpile areas. § C&D materials to be delivered to and
from the project site by barges or by trucks should be kept wet or covered to
avoid wind-blown dust. § The speed of the trucks including dump
trucks carrying C&D or waste materials within the site should be
controlled to about 10 km/hour in order to reduce the adverse dust impact and
secure the safe movement around the site. § To avoid or minimise dust emission during
transport of C&D or waste materials within the site, each and every main
temporary access should be paved with concrete, bituminous hardcore materials or metal plates and kept clear of
dusty materials. Unpaved parts of the road should be sprayed with water or a
dust suppression chemical so as to keep the entire road surface wet. |

If contaminated soil is identified, the following
mitigation measures are for the excavation and transportation of contaminated
materials (if any): § To minimize the incidents of construction
workers coming in contact with any contaminated materials, bulk
earth-moving excavation equipment should be employed; § Contact with contaminated materials can be
minimised by wearing appropriate clothing and personal protective equipment
such as gloves and masks (especially when working directly with contaminated
material), provision of washing facilities and prohibition of smoking and
eating on site; § Stockpiling of contaminated excavated
materials on site should be avoided as far as possible; § The use of any contaminated soil for
landscaping purpose should be avoided unless pre-treatment was carried out; § Vehicles containing any excavated materials
should be suitably covered to reduce dust emissions and/or release of
contaminated wastewater; § Truck bodies and tailgates should be sealed
to prevent any discharge; § Only licensed waste haulers should be used
to collect and transport contaminated material to treatment/disposal site
and should be equipped with tracking system to avoid fly
tipping; § Speed control for trucks carrying
contaminated materials should be exercised. 8km/h is the recommended
speed limit; § Strictly observe all relevant regulations in
relation to waste handling, such as Waste Disposal Ordinance (Cap 354), Waste
Disposal (Chemical Waste) (General) Regulation (Cap 354) and obtain all
necessary permits where required; and § Maintain records of waste generation and
disposal quantities and disposal arrangements. |

divert north of SCLKC Marine Park with a 15 knot speed limit to apply for the
part-journeys that cross high CWD abundance grid squares as indicatively
shown in Drawing No. MCL/P132/EIA/13-023. Both
the alignment of the northerly route and the portion of routings to be
subject to the speed limit of 15 knots shall be finalised prior to
commencement of construction based on the future review of up-to-date CWD
abundance and EM&A data and taking reference to changes in total SkyPier HSF numbers. § A maximum of 10 knots will be enforced
through the designated SCLKC Marine Park area at all times. |

Establishment of New Marine Protected
Areas/Linking of Existing Marine Parks § establishment of a new marine park matrix
that would comprise a new marine protection area around HKIA, adding an area
of 2,400 ha and also providing critical linkages between the current SCLKCMP
(an area of 1,200 ha) and the planned BMP (an area of 850 ha). Together, all three marine parks would make
up 4,450 ha of CWD marine park area. § A speed limit of 10 knots for all vessels to
travel within the marine parks areas. § A detailed study initiated and led by AAHK will be
carried out during the construction phase to review relevant previous
studies and collate available information on the ecological characters of the
proposed area for marine park designation and review available survey data
marine traffic and planned development projects in the vicinity. Based on the
findings, ecological profiles of the proposed area for marine park
designation would be established and the extent and location of the proposed
marine park be determined. § A management plan for the proposed marine park will be
proposed in consultation with AFCD, covering information on the
responsible departments for operation and management (O&M) of the marine
park, as well as the O&M duties of each of the departments involved. The management plan will be submitted to
Director of Environmental Protection (DEP) for approval before the
commissioning of the 3RS project. |

in place to provide timely and effective response and remediation of spillage
events. § Spill response equipment should be available
on site and regularly checked and maintained. § Operation of the fuel supply and refuelling
systems should be restricted to qualified and trained personnel with adequate
knowledge of the spill response procedures in place. § A penalty system should be set up to
discourage poor practices associated with maintenance of aircraft, vehicle
and refuelling systems by airport tenants and franchisees. § Detailed records of all spillage events
should be kept and maintained. |
