Use of Movable Barriers
Movable noise
barriers can be very effective in screening noise from particular items of
plant when constructing the Project. Noise barriers located along the active works
area close to the noise generating component of a PME could produce at least
10 dB(A) screening for stationary plant and 5 dB(A) for mobile plant provided
that the direct line of sight between the PME and the NSRs is blocked. |

Temporary Tree Nurseries Temporary tree nurseries may be set up
within the Project area at an early stage to allow small trees to grow during
the construction period. By the time
these trees are needed for landscape planting at the end of the construction
phase, they will have grown larger, require minimal pruning and suffer much
less damage during transplanting, as the moving distance from an on-site
rather than off-site nursery will be much smaller. The temporary tree nurseries can also temporarily
hold the existing trees to be transplanted if direct transplantation from
their original locations to the final recipient location is
impracticable. The locations of the
temporary tree nurseries should be carefully selected so that the trees can
also act as screen planting to block the views of the Project area from the

Dust Control Measures
To achieve compliance with the FSP, RSP and TSP
criteria during the construction phase, good practices for dust control
should be implemented to reduce dust impacts. The dust control measures are
detailed as follows: § Use of regular water
spraying (once every 2.5 hours or 4 times per day) to reduce dust emissions
from heavy construction activities (including ground excavation, earth moving,
etc.) at all active works area exposed site surfaces and unpaved roads,
particularly during dry weather. § Covering 80% of stockpiling area by
impervious sheets and spraying all dusty material with water immediately prior to any loading transfer
operations to keep the dusty materials wet during material handling at the
stockpile areas Relevant dust control
practices as stipulated in the Air Pollution Control (Construction Dust)
Regulation should be adopted: Good Site Management §
Good site management is important to help reduce potential air quality
impact down to an acceptable level. As a general guide, the Contractor should
maintain high standards of housekeeping to prevent emissions 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 §
Main temporary access points should be paved with concrete, bituminous
hardcore materials or metal plates and be 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 onto the
debris so that it remains wet when it is dumped. Transport of Dusty
Materials §
Vehicles 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
10 km/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 2.4 m 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 |

walled plant rooms or in specially designed enclosures; § locate noisy machine in a
basement or a completely separate building; § install direct noise
mitigation measures including silencers, acoustic louvres
and acoustic enclosure where necessary; and § develop and implement a regularly
scheduled plant maintenance programme so that equipment is properly operated
and serviced in order to maintain a controlled level of noise. Prior to the operation of the Project, noise commissioning tests for
all major fixed noise sources should be conducted. |

Construction Site Runoff The site practices outlined in ProPECC Note PN 1/94 should be followed as far as practicable in order to minimise surface runoff and erosion. The following measures are recommended to protect water quality of the inland areas: § At the start of site establishment, perimeter cut-off drains to direct off-site water around the site should be constructed with internal drainage works and erosion and sedimentation control facilities implemented. 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; § 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 standards under the WPCO. The design of efficient silt removal facilities should be based on 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 at all times; § Measures should be taken to minimise 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 site formation excavations should be discharged into storm drains via silt removal facilities; § 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 exit where practicable. 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; § 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 washing away of construction materials, soil, silt or debris into any 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 stormwater runoff being directed into foul sewers; § Precautions should be taken at any time of the year when rainstorms are likely. Actions should be taken when a rainstorm is imminent or forecasted and actions to be taken during or after rainstorms are summarised in Appendix A2 of ProPECC Note PN 1/94. Particular attention should be paid to the control of silty surface runoff during storm events, especially for areas located near steep slopes; and, § Bentonite slurries used on site should be reconditioned and reused wherever practicable. Temporary enclosed storage locations should be provided on site for any unused bentonite that needs to be transported away after all the related construction activities are completed. The requirements in ProPECC Note PN 1/94 should be adhered to in the handling and disposal of bentonite slurries. The Contractor would be required to obtain a license from EPD under the WPCO for discharge to the public drainage system or the marine environment. Construction site discharge should be collected by the temporary drainage system installed by the Contractor and treated or desilted on-site to fulfil the WPCO discharge license requirements before discharge. |

Interception channels should be provided (e.g. along the crest/edge of the excavation) to prevent storm runoff from washing across exposed soil surfaces. Arrangements should be in place to ensure that adequate surface protection measures can be safely carried out well before the arrival of a rainstorm. Measures will be taken to minimise water ingress into the excavation. Diverting any water from the excavated areas to on-site wastewater treatment facilities for treatment prior to discharge should also be performed. Other measures that need to be implemented before, during and after rainstorms are summarised in ProPECC PN 1/94. |

Accidental Spillage The Contractor should register as a chemical waste producer if chemical wastes are produced from construction activities. The Waste Disposal Ordinance (Cap 354) and its subsidiary regulations in particular the Waste Disposal (Chemical Waste) (General) Regulation should be observed and complied with for control of chemical wastes. This will prevent contamination of top soil and water pollution due to construction site runoff. Maintenance of vehicles and equipment, involving activities with potential for leakage and spillage, should only be undertaken within areas appropriately equipped to control these discharges. Oils and fuels should only be stored in designated areas which have pollution prevention facilities. To prevent spillage of fuels and solvents to any nearby storm water drain, all fuel tanks and storage areas should be provided with locks and be sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity of the largest tank. The bund should be drained of rainwater after a rain event. Disposal of chemical wastes should be carried out in compliance with the Waste Disposal Ordinance. The Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes published under the Waste Disposal Ordinance details the requirements to deal with chemical wastes. General requirements are given as follows: § Suitable containers should be used to hold the chemical wastes to avoid leakage or spillage during storage, handling and transport. § Chemical waste containers should be suitably labelled, to notify and warn the personnel who are handling the wastes, to avoid accidents. § Storage
area should be selected at a safe location on site and adequate space should
be allocated to the storage area. |

Inert
and Non-inert C&D materials
In
order to minimise impacts resulting from collection and transportation of
inert C&D materials for off-site disposal, the inert C&D materials
should be reused on-site as fill
material as far as practicable. In addition, inert C&D materials
generated from excavation works could
be reused as fill materials in local projects that
require public fill for reclamation.
The
surplus inert C&D materials will be disposed of at the Government’s PFRFs
for beneficial use by other projects in Hong Kong.
The
C&D materials generated from general site
clearance should be sorted on site to segregate any inert materials for reuse
or disposal of at PFRFs whereas the non-inert materials will be disposed of
at the
designated landfill site. In
order to monitor the disposal of inert and non-inert C&D materials at
respectively PFRFs and the designated landfill site, and to control
fly-tipping, it is recommended that the Contractor should follow the DEVB
Technical Circular (Works) No.6/2010 for Trip Ticket System for Disposal of
Construction & Demolition Materials issued by Development Bureau. In
addition, it is also recommended that the Contractor should prepare and
implement a Waste Management Plan detailing their various waste arising and
waste management practices in accordance with the relevant requirements of
the ETWB Technical Circular (Works) No. 19/2005 Environmental Management on
Construction Site.

Chemical
Waste
If
chemical wastes are produced at the construction site, the Contractor will be
required to register with the EPD as a chemical waste producer and to follow
the guidelines stated in the “Code of Practice on the Packaging Labelling and
Storage of Chemical Wastes”. Good quality containers compatible with the
chemical wastes should be used, and incompatible chemicals should be stored
separately. Appropriate labels should be securely attached on each chemical
waste container indicating the corresponding chemical characteristics of the
chemical waste, such as explosive, flammable, oxidising, irritant, toxic,
harmful, corrosive, etc. The Contractor should use a licensed collector to
transport and dispose of the chemical wastes at the approved Chemical Waste
Treatment Centre or other licensed recycling facilities, in accordance with
the Waste Disposal (Chemical Waste) (General) Regulation.
Potential environmental impacts arising from the handling
activities (including storage, collection, transportation and disposal of
chemical waste) are expected to be minimal with the implementation of
appropriate mitigation measures as recommended.

If contaminated soil is identified, the following mitigation measures are for the excavation and transportation of contaminated materials (if any): § To minimise 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. § 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

Sensitive
Design and Disposition All proposed hard structures should be
sensitively designed in a manner that responds to the existing and planned
landscape context, and minimises potential adverse landscape and visual
impacts. The structural design should
seek to reduce the apparent visual mass through the use of natural materials
such as wooden frame and semi-transparent panels. Subdued tones should be considered for the
colour palette with non-reflective finishes to reduce glare effect. Site specific
measures, such as the disposition of the key structures closer to the
northern slopes, the design of building forms as extension along the existing
slope topography, the use of concave roof form and the location of ride
platforms on or near the slopes to minimise structural support, should also
be considered for better integration with the surroundings and minimisation
of potential visual impacts. |

of possible light pollution and night-time glare to the surroundings. Consideration shall be made by the lighting
designers to the following measures: § Lighting shall be
designed with due consideration of mounting height and direction of light
fixtures so as not to point directly towards any sensitive receiver. § Lighting shall be
arranged with due consideration of reflectance so as to avoid glare effect. § Lighting shall be regularly
monitored during operation. § Lights located
adjacent or in proximity to neighbours shall be carefully designed to prevent
possible light intrusion. § Lighting operation
schedule shall specify only lights necessary for security to be left on after
business hours. § Paving materials
should be selected as necessary to reduce potential glare from surface
reflectance. § Particular attention
should be paid to the use of lighting having a high intensity or harsher tone
(e.g. metal halide lamps). § Lights shall generally
be models having precise cut-off range (such as full cut-off optics where
available and practicable) and if necessary be fitted with adjustable
anti-glare shields. |
