Proposed 18
holes Golf Course Layout Design For the
construction activity which is unavoidable near natural streams (within the
buffer zone), mainly the construction of crossings, preventative mitigation
measures during the construction stage should be follow by the Contractor,
they are shown as follows: l The proposed works site inside or in the
proximity of natural streams should be temporarily isolated, through by
placement of sandbags or silt curtains and properly supported by props, to
prevent adverse impacts on the stream water qualities; l The natural bottom and existing flow in
the stream should be preserved to avoid disturbance to the stream habitats; l No direct and indirect discharge into the
natural stream is allowed from any construction work activities; l Stockpiling of construction material, if
any, should be properly covered and located away from any natural stream; l Monitor rain forecast closely and cover
any exposed spoil when rainstorms are forecated. Debris should be properly disposed of
before rainstorm to avoid any inadvertent wash away into the stream; and l Removal of existing vegetation alongside
the stream should be avoided.
When disturbance to vegetation is unavoidable, all disturbed areas
should be hydroseeded or planted with suitable
vegetation to blend in with the natural environmental upon completion of
works. |

Runoff and Drainage
Management u Diversion
of upstream flows around the works areas for stream crossings and underground
pipes: To minimize the
impact of upstream runoff on the Works area by preventing storm flows
reaching the work areas. This will be done through provision of upstream
cut-off drains to intercept the flows and divert them around the Works
area. It would convey flows to
downstream stream courses, or other elements of temporary drainage systems
(such as storage facilities). u Temporary
covering the works areas during severe storm events: Significant rainstorm events can be
reasonably well forecast and when heavy rain is predicted, mitigation
measures should be provided for the vulnerable areas by using tarpaulins,
plastic sheets or other temporary covering to protect works area and minimize
damage and erosion. It is
recommended not to cover the newly establishment grass areas, and if
unavoidable, this should only to be done on a short term basis (less than 24
hours). u Silt
traps and sedimentation tanks for main discharge routes form works area: Sufficient and suitably sized silt traps
and/or sedimentation tanks should be provided at the downstream ends of the
systems to remove suspended solids prior to discharge. The discharge water quality shall be
compliant with the TM on Standards for
Effluents Discharged into Drainage and Sewerage Systems, Inland and Coastal
Waters under the WPCO. The
required volume of the sedimentation tanks will depend on the catchment area served. Multiple tanks in series may also be
required where runoff might be expected to be silty. u The design details of the temporary drainage system
at turf establishment area follow the same principles of the permanent
drainage system. However the
component pipes, tanks, lakes and/or pumps may differ in size, shape,
location, etc. from that of the permanent system, dependent upon the
temporary runoff areas as compared with those of the permanent system. Additionally or alternatively, the
temporary drainage system may consist of other methods to control soil
erosion and/or to facilitate the collection of surface water runoff. The temporary
drainage system will function during the period of time in which the
permanent system is not yet completed.
This circumstance will arise from the fact that the golf holes,
inclusive of the permanent drainage system, will be constructed individually. As a result, the permanent drainage
system may not be completed in its entirety until connection is made from
each respective golf hole area to the
lake/reservoir. As the permanent
drainage system is completed for each hole, the corresponding temporary
system will be decommissioned and reused elsewhere. The temporary drainage
system will be in use until the permanent system is functional in a given
area. Once the permanent system
is functional in a given area, the temporary system will be decommissioned
and, wherever possible, the components re-used in another temporary drainage
system installed elsewhere. It is
anticipated that the maximum duration of use for the temporary drainage
system in any given area will be one-year. The storage tanks
and/or lakes will be designed to segregate suspended solids (or pollutants as
may be the case in plant/equipment storage and refueling areas) as may be
necessary by contract requirements and reuse. u No irrigation, fertilizer and pesticide
applications to the turf would be permitted during rainstorm events or when
heavy rainstorm is predicted 24 hours before the application. u Runoff from materials storage areas,
particularly fuel and chemicals storage area should be separated from the
main drainage systems (bunded, if necessary) and
provided with dedicated facilities throughout the construction period, such
as petrol interceptors. The Contractor
shall follow good site practices and be responsible for the design,
construction, operation, and maintenance of all the mitigation measures as
specified in ProPECC PN1/94 on construction site drainage
through the construction period.
These practices include: l
Temporary
ditches should be provided to facilitate run-off discharge into appropriate
watercourses, via a silt retention pond. l
All
drainage facilities and erosion and sediment control structures should be
inspected monthly and maintained to ensure proper and efficient operation at
all times. l
Excavation
of soil that cannot be avoided during the wet season, and exposed surface or
open stockpiles should be covered with tarpaulin or other means. Other measures that need to be
implemented before, during and after rainstorms are summarized in ProPECC PN1/94. l
Exposed
soil areas should be minimized to reduce potential for increase siltation and contamination of runoff. l
Earthwork
final surfaces should be well compacted and subsequent permanent work (turf
establishment) should be immediately performed. l
The
Contractor shall contain within the site all surface runoff generated from
the construction works, concreting works, dust control and vehicle washing,
etc. l
The
Contractor shall arrange other measures, such as provision of sand bags or
temporary diversion systems to prevent washing away of soil, silt or debris
into any nearby natural streams.
Any runoff shall be diverted into appropriate sediment traps before
discharging to the nearby drainage system. The discharge water quality shall be
compliant with the TM on Standards for
Effluents Discharged into Drainage and Sewerage Systems, Inland and Coastal
Waters under the WPCO. l
The
Contractor shall observe and comply with the Water Pollution Control
Ordinance (WPCO) and its subsidiary regulations by implementing environmental
protection measures (such as the use of silt traps) and preventing any point
or non-point source of pollution. |

Concrete
bridge construction No work is
allowed to come into contact with the underlying stream bed during the
concrete bridge construction.
During the construction of precast concrete
bridge, if necessary, precaution measures should be taken to ensure no
potentially polluting liquid or solid wastes fall into the stream. This is essential to avoid water
quality impacts within ecologically sensitive streams. The Contractor
shall good site follow practices, including, but no limited to:: l
Construction
work area for the precast concrete should be
outside the designated stream buffer zone area; l
The
designated work area for precast concrete work
should be covered to minimize the potential water runoff during rain from the
construction area; l
All
water used within the concrete work area should be collected, stored and
recycled to reduce resource consumption.
Stormwater runoff from the works areas fro precast concreting works should drain under gravity
towards a sedimentation basin.
The overlying water from the sedimentation basin should be recycled
for reuse within the plant. The
deposited sediment should be dewatered and the dry matter should require
disposal off-site. No water
should be discharged outside the boundary of the precast
concrete works area; l
The
use of tarpaulin sheet or other means (water impermeable texture) should be
placed beneath precast concrete beam level (must be
above the stream bed level) to capture any falling object during installation
of precast concrete bridge on the footings or
abutments; l
Prohibition
of any direct and indirect discharge into the streams; l
The
concrete bridge and footings of abutments must be completely above the high
water mark; l
All
equipment and machinery must be free of leaks or excess oil and grease; l
Equipment
refueling or servicing or storage of fuel must be undertaken at a minimum of
30 meters from the stream; l
Prevent
soil and trash from getting into stream during construction by use of silt
fence, fiber rolls, gravel bags and other effective means; l
All
bare soil (abutment slope or temporary stockpile) must be covered with
tarpaulin or other means before forecast rain; and l

Dredging
during Construction of Desalination Plant’s intake and outfall The intake and
outfall pipelines will be constructed by dredging the seabed to form a trench
and backfilled with a layer of bedding material (quarry run stone) before
putting the pipelines in place.
Once in place, the pipelines are covered with layers of rock armour on top of the pipelines to protect the pipelines
against damage by wave action.
The alternative backfilling material is from rock excavated during
site formation if suitable. The materials used
for the backfilling at the intake and outfall pipelines are stone and rock armour only. Transfer of
backfilling materials onto the seabed from barge should be conducted by
careful grabbing and unloading to seabed (to minimize sediment migration),
thereby minimize impacts on water quality to nearby water sensitive
receivers. As a preventative measures, silt curtain
will also be required during the backfilling activities. The expected backfilling duration is
approximate 2 months. The Contractor
shall use backhoe for dredging works at a water depth of less than In order to avoid
pollution during dredging, transporting and dumping of marine mud. Pollution avoidance measures shall
include but not be limited to the following: · The maximum daily dredging rate for closed
grab dredger should be · The maximum daily dredging rate for
backhoe should be · Silt curtain should be installed for any
dredging methods to protect the WSRs; · Closed grabs or sealed grabs should only
be used for locations with water depths > · Backhoe should only be used for locations
with water depths < · All equipment should be designed and
maintained to minimise the risk of silt and other
contaminants being released into the water column or deposited in locations
other than designated location; · Mechanical grabs should be designed and maintained
to avoid spillage and should seal tightly while being lifted; · No trailing suction hopper dredgers would
be deployed for the dredging of marine mud; · All vessels should be sized such that
adequate clearance is maintained between vessels and the sea bed at all
states of the tide to ensure that undue turbidity is not generated by
turbulence from vessel movement or propeller wash; · All pipe leakages should be repaired
promptly and plant shall not be operated with leaking pipes; · Before moving the vessels which are used
for transporting dredged materials excess material should be cleaned from the
decks and exposed fittings of vessels and the excess materials should never
be dumped into the sea except at the approved locations; · Adequate freeboard should be maintained on
barges to ensure that decks are not washed by wave action; · The Contractor should monitor all vessels
transporting material to ensure that no dumping outside the approved location
takes place. The contractor should keep and produce logs and other records to
demonstrate compliance and that journey times are consistent with designated
locations and copies of such records should be submitted to the engineer; · All bottom dumping vessels should be
fitted with tight fitting seals to their bottom openings to prevent leakage
of material; · Loading of barges and hoppers should be
controlled to prevent splashing of dredged material to the surrounding water,
and vessels should not be filled to a level which will cause overflowing of
material or polluted water during loading or transportation; and · The engineer may monitor any or all
vessels transporting material to check that no dumping outside the approved
location nor loss of material during transportation
takes place. The contractor should provide all reasonable assistance to the
engineer for this purpose. In addition,
baseline water quality monitoring before commencement of the marine works
shall be carried out in the nearby waters to obtain baseline information for
subsequence monitoring. Regular
and frequent water quality monitoring shall be carried out throughout the
whole construction period to ensure the water quality during construction is
well within the established environmental guidelines and standards. Silt Curtain In order to minimize impacts during the
whole construction period of desalination plant’s intake and discharge
outfall, silt curtains should be utilized to minimize sediment
migration. The Contractor shall
be responsible for the design, installation and maintenance of the silt
curtains to minimize the impacts on the water quality and the protection of
water sensitive receivers. The
design and specification of the silt curtains shall be submitted by the
Contractor to the Engineer for approval.
Area of the silt curtain to enclose the works area should be minimized
in order to reduce the disturbance of ecological sensitive areas nearby. A typical suspended solids reduction of 75% can be achieved with the
incorporation of silt curtain. Two-layer silt curtains have generally been
used for dredging projects of larger scale to further ensure this reduction.
However, as the scale of proposed project is considered small, it is
recommended to use single layer silt curtain which can achieve a minimum 75%
suspended solids reduction. Silt curtains
shall be formed from tough, abrasion resistant, permeable membranes, suitable
for the purpose, supported on floating booms in such a way as to ensure that
the sediment plume shall be restricted to within the limit of the works area. The silt curtain
shall be formed and installed in such a way that tidal rise and fall are
accommodated, with the silt curtains always extending from the surface to the
bottom of the water column. The removal and reinstallation of such curtains
during typhoon conditions shall be as agreed with the Director of Marine
Department. The Contractor shall regularly inspect the
silt curtains and check that they are moored and marked to avoid danger to
marine traffic. Any damage to the silt curtain shall be repaired by the
Contractor promptly and the works shall be stopped until the repair is effected to the satisfaction of the Engineer. |

General
Construction Activities Debris and
refuse generated on-site should be collected, handled and disposed of
properly to avoid entering adjacent watercourse. Stockpiles of construction materials
should be kept covered when not being used. Oils and fuels
should only be stored/handled in designated areas
with pollution prevention facilities.
Oil interceptors need to be regularly inspected and cleaned to avoid
wash-out of oil during storm conditions. Contractor
should provide a safe storage area for chemicals on site. The Contractor is required to register
as a chemical waster producer if chemical wastes would be produced from the
construction activities. All fuel tanks
should be provided with locks and be sited on sealed areas within bunds of
capacity equal to 110% of the storage capacity of the largest tank. Good
housekeeping practices and staff training are required to minimize careless
spillage and keep the work space in a tidy and clean
conditions at all times.
Accidental spillage of chemicals in the works area would directly
affect the aquatic environment.
It is recommended that the Contractor should develop management procedures
for chemical and implement an emergency plan to deal with chemical spillage
in case of an accident. Disposal of chemical wastes should be
carried out in compliance with the Waste Disposal Ordinance. The chemical waste should be
transported to a facility licensed to receive chemical waste, such as the
Chemical Waste Treatment Facility at Tsing Yi. The Code of Practice on the Packaging,
Labelling and Storage of Chemical Wastes details
the requirements to deal with chemical wastes. |

clean the chemical toilets on a regular basis which will be and disposed of at government sewage
treatment facilities; ·
Regular
environmental audit on the construction site can provide an effective control
of any malpractices and can achieve continual improvement of environmental
performance on site. It is
anticipated that sewage generation during the construction phase of the
project would not cause water pollution problem after undertaking all
required measures; and ·
Notices
should be posted at conspicuous locations to remind the workers not to
discharge any sewage or wastewater into the nearby environment during the
construction phase of the project. |

Concrete batching plant All water used
within the concrete batching plant will be collected, stored and recycled to
reduce resource consumption. This
includes water used in the concrete batching process, truck cleaning, yard
washing and dust suppression spraying.
All spent dust suppression effluent will be collected and
recycled. To minimize the
potential water quality impacts that may generate from the concrete batching
plant, a drainage system should be provided in this
site. The batching plant area should be channelled
to collect concrete washings for further treatment before reuse on-site and
prevent concrete washings from directly entering the any stream or seawater. Site runoff should also be collected
through the drainage system. To minimize the generation of contaminated site
runoff from concrete production area, the concrete batching plant should be
sheltered. Concrete
washings and site runoff should be pumped to a wastewater treatment system
with a sedimentation unit for removal of suspended solids such as waste
concrete particles, silt and grit in order to achieve the discharge
standards. pH
adjustment should also be applied if the pH value of the collected concrete
washings and site runoff is higher than the pH range specified in the
discharge licence. This can be achieved by adding
neutralizing regents, i.e. acidic additive. A discharge licence
should be applied from The drainage
system should be maintained on a regular basis to remove the deposits on the
channels. The sedimentation and pH adjustment systems should also be checked
and maintained by competent persons to ensure that the systems are
functioning properly at all times. The deposited
sediment will be dewatered and the dry matter will require disposal
off-site. The estimated maximum
concentrate batching operation period during construction is 20 months. Sand, gravel
and other bulk materials will be delivered from the production area by
conveyor boats or derrick barges to the temporary barging point, and the
material will then be loaded onto dump trucks by loaders and delivered to the
on-site storage areas. Regular
environmental inspections should be conducted to check the environmental
performance of daily operation.
These inspections will ensure proper installation and maintenance of
pollution control measures, such as checking of sedimentation basin,
wastewater recycling facility and enclosure of stockpiles, and the
implementation of other mitigation measures. |

Good
management and control can prevent the generation of significant amounts of
waste. Waste reduction is best achieved at the planning and design
stage, as well as by ensuring the implementation of good site
practices. Recommendations to achieve waste reduction include: u 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; u separate labelled bins shall be
provided to segregate aluminium cans from other general refuse generated by
the work force, and to encourage collection of by individual collectors; u any unused chemicals or those with
remaining functional capacity shall be recycled; u maximising the use of reusable
steel formwork to reduce the amount of C&D material; u prior to disposal of C&D waste,
it is recommended that wood, steel and other metals shall be separated for
re-use and / or recycling to minimise the quantity of waste to be disposed of
to landfill; u proper storage and site practices
to minimise the potential for damage or contamination of construction
materials; u
plan and stock construction materials carefully to minimise amount of
waste generated and avoid unnecessary generation of waste; u minimize over ordering of concrete,

be reused on-site as backfilling material. C&D waste, such as wood,
plastic, steel and other metals should be reused or recycled and, as a last
resort, disposed of to landfill. A suitable area(s) should be designated
within the site for temporary stockpiling of C&D material and to
facilitate the sorting process. The stockpiling/sorting area should be

Chemical
Waste Where
the construction processes produce chemical waste, the Contractor must

standing surfaces draining via oil interceptors shall be provided in works
area compounds. Interceptors will be regularly emptied to prevent release of
oils and grease into the surface water drainage system after accidental
spillages. The interceptor should have a bypass to prevent flushing during
periods of heavy rain. Oil and fuel bunkers should be bunded
to prevent discharge due to accidental spillages or breaches of tanks. Waste
collected from any grease traps should be collected and disposed of by a
licensed contractor. Any
construction plant which is likely to leak oil,
should have absorbent inert material e.g. sand, placed beneath it. This
material should be replaced on a regular basis and the contaminated material
should be stored in a designated, secure place. Any sand used for soaking oil
waste is classified as chemical waste and should be disposed of in accordance
with the Waste Disposal (Chemical
Waste) (General) Regulations. Lubricants
and waste oils are likely to be generated during the maintenance of vehicles
and mechanical equipment. Used lubricants will be collected and stored in
individual containers which are fully labelled. The
containers should be stored in a designated secure place. If possible such
waste should be sent to oil recycling companies; there are also companies
which collect empty oil drums for reuse or refill. Oil
and lubricant wastes are classified as chemical wastes, and if not recycled,
should be collected by licensed collector and should be treated at the
Chemical Waste Treatment Centre, Tsing Yi, or other
sites licensed for disposal of waste oil. A trip ticket system operates to
control the movement of such chemical waste and tickets have to be produced
upon the request of Some
paints and solvents are classified as chemical waste and, if used on site,
will be subject to the stringent requirements of the Waste Disposal (Chemical Waste) (General) Regulation. Empty paint
cans should be recycled or collected as waste. Any dry paint waste should be
swept up and collected in containers for disposal. No lubricants, oils, solvents or
paint products should be allowed to discharge into water courses, either by
direct discharge, or as contaminants carried in surface water runoff from the

A
closed low flow drainage system is proposed to capture runoff by collecting
surface water from the majority of the proposed third golf course and pump it
back to the existing reservoir for reuse in irrigation. The drainage system design and concept
approach for the proposed third golf course is similar to the existing golf
course, which has been seen as successful, to minimize the impacts to nearby

To
avoid impacts on hard coral colonies, a floating barging point (Figure 9.8)
is proposed to replace the original design (baring point supported by
piles) (Figure 9.7).
This could avoid any construction or damage on the shallow waters
where the corals are located.
Impacts on corals would thus be avoided. |

To compensate loss of trees, a total of 42

planted on the new golf course (see tree survey reports). 90% of these trees are native, while
76% of these will be light to heavy standard trees, which will provide
instant breeding and foraging habitats for birds and butterflies. The use of light to heavy standard
trees is more preferable to seedlings as bigger trees provide habitats of

Since the exact
cut areas on site during construction by the Contractor have not been
determined at this stage, the Contractor should implement the suitable
precautions and preventive measures for the discovery of buried or abandoned
ordnance during the construction. Moreover, it is recommended that standard
good practice should be implemented during the construction phase in order to
minimize any potential exposure to contaminated soils or groundwater. These
measures include: · The Contractor should sweep the area of
intended excavation with a metal detector to check any ordnance underneath
the ground prior to any excavation. · For any detection of metals under the
ground, the Contractor should cease work immediately before confirming the
identity of the cause. For any suspect of artillery ordnance, Hong Kong
Police Force should be informed. · The use of bulk earth-moving excavator
equipment would minimise construction workers’
potential contact with the contaminated materials; · Exposure to any contaminated materials can
be minimised by the wearing of appropriate clothing
and personal protective equipment such as gloves (when interacting directly
with suspected contaminated material), providing adequate hygiene and washing
facilities and preventing smoking and eating during such activities; · Stockpiling of contaminated soil should be
avoided. If this cannot be avoided, the stockpile of contaminated materials
should be segregated from the uncontaminated ones. Moreover, the contaminated
materials should be properly covered with waterproof material (e.g. tarpaulin
sheet) to avoid leaching of contaminants, especially during rainy season. · 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 leakage during transport or during wet conditions; · Only licensed waste haulers should be used
to collect and transport any contaminated material to an appropriate disposal
site and procedures should be developed to ensure that illegal disposal of
waste does not occur; · Necessary waste disposal permits should be
obtained, as required, from the appropriate authorities, in accordance with
the Waste Disposal Ordinance (Cap 354),
Waste Disposal (Chemical Waste)
(General) Regulation (Cap 35), as required; · Records of the quantities of wastes
generated and disposed of should be maintained; · Adequate washing facilities should be
provided on site; and · In accordance with good construction
practice, silt traps should be used to reduce the impact to drainage caused
by suspended solids arising from disturbed ground, or any construction
materials such as cement and gravel. Groundwater should be disposed of in
accordance with the Water Pollution Control
Ordinance (Cap 358). |

Based on preliminary
site investigation, the site is considered as a potentially land contaminated
site as hotspots of contamination of lead and sulphur
were identified. Further
investigation for land contamination at this site is therefore required and
is detailed in the Contamination Assessment Plan ( |

Prevention
of Contamination Impact In order to prevent the chemicals from contaminating
the land, a Turfgrass Management Plan ( As present in the water quality assessment section,
four main chemicals are used for existing golf courses,
they are nitrogenous fertilizers, herbicides, fungicides and insecticides.
The approach should be to minimize application of fertilizers and this is
also driven by economic requirements to minimize recurrent costs. Healthy growth rates are achieved when
the grass is not over fertilized or over watered. A balanced programme allows the grass to stand up to wear and
develop disease resistance. In line with existing practice, the following
mitigation measures will be implemented: ·
Nutrient
status will be monitored every 6 months of the year through the aid of soil
and leaf tissue tests. Tests help determine the optimum nutrient provisions
for turf grass. ·
A
slow release fertilizer will be used to help minimize the amount of nitrate
leached from the soil. ·
Applying
low quantity of fertilizer is recommended to minimize the leaching due to the
active uptake. ·
Applications
will not be made if heavy rain is forecast to minimize the significant
nitrogen runoff. |
