Prevention of Construction
Runoff from Polluting the Nearby Watercourse and Ecological Sensitive Areas · Minimisation
of the Development Footprint. The
preliminary Master Layout Plan minimised the development footprint within the
Development Site (of approximately 1.625 ha and comprised only about 39.6% of
the total site area) so as to reduce the extent of site formation and earth
work activities, and the subsequent potential risk of construction
runoff. |

· Completion of Sha Lo
Tung Road Improvement in advance.
Before any construction works are undertaken within the Development
Site, the Sha Lo Tung Road should be improved with well designed drainage
systems. All of the surface run-off
will be collected by the temporary drainage system with sufficient number of sandtraps
(with sufficient capacity) and then discharged to the newly constructed
stormwater drainage system along the improved Sha Lo Tung Road. |

· Restrict
Earthworks to the Dry Season.
Earthworks within the Development Site will only be undertaken during
the dry season (November through March) in order to avoid the risk of
construction runoff reaching ecological sensitive areas. With the implementation of this measure,
the risk from excessive construction runoff in the event of a heavy rainstorm
can be reduced. Major earthworks will
be strictly prohibited during the wet season to minimise ecological risk to
the Sha Lo Tung Valley. |

· Adoption
of Construction Sequences. Given that
the Development Site is elongated in shape and hilly in nature, the
construction sequence should be well managed in order to limit the volume of
surface runoff and treated effluent generated on-site, in particular during
the wet season (works other than earthworks).
In order to limit the size of exposed areas and volume of the surface
runoff, the construction activities will be carried out sequentially (phase
by phase and sub-area to sub-area) rather than in parallel (refer to Site
Formation Construction Sequence as shown in Figure 3.13 in
the EIA Report and Road Improvement
Work Plan as shown in Figure 3.22 in the EIA Report). The site formation works in the northern
part of the Development Area will be carried out at a later phase in order to
avoid early exposure of the soil and hence to prevent muddy water from
spilling over into the Sha Lo Tung SSSI and Sha Lo Tung Stream as well as the wet
abandoned agricultural land. Such
arrangement will assist in ensuring that construction runoff is not
discharged into Sha Lo Tung Stream. |

· Provision
of Temporary Drainage Channels. Peripheral
temporary drainage channels (special designed U-channel, like a “J” shape
will be used) (see Figure
6.3) should be constructed along the lower side of all of the works areas
within the Development Site prior to the commencement of the construction
works. All of the natural surface
run-off will be collected by the temporary drainage system with a sufficient
number of sandtraps and oil interceptors and then discharged to the newly
constructed stormwater drainage system along Sha Lo Tung Road. The drainage system capacity shall be
designed for a 1:20 year storm event.
A sandtrap of large capacity is proposed to connect between the
temporary drainage system within the Development Site and the newly
constructed stormwater drains beneath Sha Lo Tung Road. All surface runoff within the site will be
continuously pumped to this sandtrap through a bendable water pipe (e.g.
rubber pipe) before it is discharged from the site. Due to the lower level at the surface water
collection point within the Development Site, the surface water within the
Site will be transferred to temporary storage tanks (after passing through
sandtraps) in which a submersible pump will operate to continuously pump the
surface runoff to the proposed sandtrap.
A spare submersible pump will be put in place in the storage tank for
contingency purpose. |

· Provision
of Silt Removal Facility. Sandtraps
will be provided on site for wastewater treatment before discharge. The Contractor will ensure that the
sandtraps will be large enough to handle the site runoff / discharges and
will be properly maintained. The
design of efficient silt removal facilities should be based on the guidelines
in Appendix A1 of ProPECC PN 1/94. The
effectiveness of the sand trap will be checked and maintained regularly. The sand traps should be cleaned out when
the volume of settled sediments amounts to 10% of the total volume of the
trap. |

· Separate
Temporary Drainage System for Natural Runoff.
The temporary drainage system may not be able to handle high volume of
natural surface runoff from the surrounding hills during heavy
rainfalls. The surface runoff from the
Site will be separated from the natural hinterland surface runoff by
deployment of two drainage systems. To
cater for the surface water running from the hinterland in particular at the
southern end to the low profile of the Site, a separate temporary drainage
system including catchpits and drainage pipes will be used to direct the
natural surface runoff without any contamination due to site activities to
north side of the site (Figure 6.3 in the EIA Report). |

· Erection
of Site Hoardings and Chain-link Fence with Seal. Continuous site hoarding and chain-link
fence will be erected along the temporary drainage system enclosing the
entire Development Site (Figure 6.4 in the EIA Report). The hoardings and chain-link fence should
be firmly attached to the channel (any gaps are to be filled and cemented) in
order to avoid any accidental spilling over the peripheral channel to the
nearby streams. All of the excessive
runoff due to heavy rainfall or overflow of storage tanks/ sandtraps could be
retained within the Site and avoid any accidental discharges into the Sha Lo
Tung SSSI Stream as well
as the wet abandoned agricultural land.
The erection of the hoardings and chain-link fence will avoid any
additional impacts to the existing trees. |

Good Site
Practices · Discharges
to the natural water courses shall only take place when the effluent complies
with the requirements under the Water
Pollution Control Ordinance.
Discharges in the water gathering ground should meet Group A standards
for inland waters specified in the Technical Memorandum, Standards for
Effluent Discharged into Drainage and Sewerage Systems, Inland and Coastal
Waters. · All
exposed earth areas will be paved or hydroseeded as soon as possible after
earthworks have been completed, or alternatively, within 14 days of the
cessation of earthworks, where practicable.
In the event of rain or at any time when rainstorms are likely to
happen, exposed surfaces should be covered by tarpaulin or by other means. · All
drainage facilities and erosion and sediment control structures will be
regularly inspected and maintained to ensure proper and efficient operation
at all times and particularly following rainstorms. Deposited silt and grit will be removed
regularly and disposed of by spreading evenly over stable, vegetated areas. · Measures
will be taken to reduce the ingress of site drainage into excavations. If the excavation of trenches in wet
periods is necessary, they will be dug and backfilled in short sections
wherever practicable. Water pumped out
from trenches or foundation excavations will be discharged into storm drains
via silt removal facilities. · Open
stockpiles of construction materials (for example, aggregates, sand and fill
material) should be covered with tarpaulin or similar fabric during
rainstorms. Measures will be taken to
prevent the washing away of construction materials, soil, silt or debris into
any drainage system. · The
wheels of all vehicles leaving and entering the construction site shall be
washed to minimise the carry over of mud onto Sha Lo Tung Road and into the
water gathering grounds. Wheel wash
water shall be recycled and only discharged into the temporary drainage
system. · Manholes
(including newly constructed ones) will always be adequately covered and
temporarily sealed so as to prevent silt, construction materials or debris
being washed into the drainage system. · Precautions
to be taken at any time of year when rainstorms are likely, actions to 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 PN
1/94. Particular attention will be
paid to the control of silty surface runoff during storm events, especially
for areas located near steep slopes. · Oil
interceptors will be provided in the drainage system and regularly emptied to
prevent the release of oil and grease into the storm water drainage system
after accidental spillages. The oil interceptors should be
cleaned when the volume of oil amounts to 30% of the total volume of the oil
interceptor. The interceptor
will have a bypass to prevent flushing during periods of heavy rain. · The
sandtraps should be cleaned out when the volume of settled sediments amounts
to 10% of the total volume of the traps. |

· Water
Quality Monitoring should be conducted at three monitoring stations of the Sha
Lo Tung Perennial Stream (R1-U, R1-M and R1-D) (see Figure 12.2
in EIA Report for their locations). The monitoring parameters are detailed in Sections 5.2.1 and 5.3.1 of this Manual.
i.
The baseline monitoring should be
undertaken 3 days per week for at least four weeks at the designated stations
prior to the commencement of the construction works. Baseline monitoring schedule prepared by
the ET should be faxed to the IEC, EPD and WSD 1 week prior to the
commencement of baseline monitoring.
ii.
Impact monitoring for in-situ parameters and SS should be
undertaken 3 days per week during the course of construction works. Impact monitoring for oil and grease,
ammonia nitrogen, total reactive phosphorus and 5-day biochemical oxygen
demand should be carried out once per month during the construction
phase. The proposed water quality
monitoring schedule prepared by the ET should be faxed to the IEC, EPD and
WSD on or before the first day of the monitoring month. The IEC, EPD and WSD should be notified
immediately of any changes in schedule by fax.
iii.
Post-project monitoring should be
undertaken for 3 days at the designated stations within a week after the
completion of the construction works.
Post-project monitoring schedule prepared by the ET should be faxed to
the IEC, EPD and WSD 1 week prior to the commencement of post-project
monitoring. The purpose of the
monitoring is to verify that contamination to the watercourses by sewage, oil

Surface Runoff and
Drainage After identifying
the sub-divisions in the natural topography based on their drainage
characteristics it is possible to develop mitigation measures to minimize the
impact of the development on the existing drainage system and in particular
the discharge into Sha Lo Tung Stream.
The approach to drainage impact mitigation measures has as an
overriding objective to retain and maintain the existing quality and quantity
of water flow into the Sha Lo Tung natural stream systems downstream of the
Development Site. In doing so it is
intended to draw clear distinctions between the following run-off and
drainage circumstances: · Development
Site subject to vehicular traffic (“development vehicular zones”) – where the
run-off will be collected using back of kerb filter drains, trapped road
gullys and a piped stormwater system.
This will discharge run-off to a pumping station located beneath the
car park area with all flows being discharged back over the crest of the
access road and into the structured road drainage to be provided as part of
the road improvements ; · Developments
Site with no vehicular traffic (“development non-vehicular zones”) – where
porous or semi permeable paved surfaces will be used in association with
grassed swales and soakaways to attenuate run-off. Terraced construction will control the rate
of surface runoff with catchpits providing oxygenation and solids removal at
the steps formed. The run-off from the
development non-vehicular zone will be routed to pass through vortex grit
separator beneath the proposed car park (location refer to Figure 3.8 of the EIA
Report) to remove sediments associated with “first flush” flow (details
refer to Annex C of the EIA
Report). After removal of
sediments clear water can be discharged via a storage tank and non-developed
buffer zones (undeveloped naturally vegetated land between the development
boundary and the existing stream system) into the existing stream system,
which act to reduce the energy and volume of run-off flows before they enter
the existing Sha Lo Tung stream system.
The vortex grit separator will be regularly cleaned and maintained in
good working condition. The initial
frequency for clearing the vortex grit separator would be based on systematic
monitoring at the start of the wet season, after each significant rainfall
event (amber/T3 or above) and at intervals not exceeding one month between
April and October. Removal with
clearing/disposal as required. This
will provide the required information on the volume of washed down material
and this can be used to determine an effective and efficient clearing
frequency programme. |

· Adoption
of Construction Sequences. Given that
the total length of Sha Lo Tung Road is approximately 2.3km, the construction
sequence will be well managed in order to limit the volume of surface runoff
and treated effluent generated on-site, in particular during the wet season
(works other than earthworks). In
order to limit the size of exposed areas and volume of the surface runoff,
the construction activities will be carried out sequentially (phase by phase)
rather than in parallel (refer to Road Improvement Work Plan as shown in Figure 3.22 of the EIA Report. |

· Provision
of Temporary Drainage Channels. To
prevent the discharge of silty surface run-off to the existing watercourse,
an effective temporary drainage system will be introduced for the road
improvement work. Prior to the
construction, temporary hoarding will be erected and sandbags be placed at
toe of the hoarding within the works site (refer to Figure 6.4
in the EIA Report) as to prevent
any silty water flowing out of the works site. As shown in Figure 3.22
in the EIA Report, at least two
temporary sandtraps connecting with temporary surface drainage will be
proposed at each phase of road improvement works (except Phase 3) prior to
discharging into the nearest watercourse to avoid any excessive sediment or
blockage of existing natural drainage system.
Similar to the construction activities within the Development Site,
all of the surface run-off generated along the section close to Sha Lo Tung
Valley (approximately half of the Phase
3) will be collected by the temporary drainage system with a sufficient
number of sandtraps (with sufficient capacity) and oil interceptors and then
discharged to the newly constructed stormwater drainage system along the
improved Sha Lo Tung Road. The
drainage system capacity shall be designed for a 1:20 year storm event. A sandtrap of large capacity is proposed to
connect between the temporary drainage system within the Development Site and
the newly constructed stormwater drains beneath Sha Lo Tung Road. All surface runoff within the site will be
diverted to this sandtrap before it is discharged out from the site. Due to the lower level at the surface water
collection point within the Development Site, the surface water within the
Site will be stored in temporary storage tanks (after passing through
sandtrap) in which a submersible pump will operate to continuously pump the
surface runoff to the proposed upstream sandtrap. A spare submersible pump will be put in
place in the storage tank for contingency purpose. |

Practices · Discharges
to the natural water courses shall only take place when the effluent complies
with the requirements under the Water Pollution Control Ordinance. Discharges in the water gathering ground
should meet Group A standards for inland waters specified in the Technical
Memorandum, Standards for Effluent Discharged into Drainage and Sewerage
Systems, Inland and Coastal Waters. · All
exposed earth areas will be paved or hydroseeded as soon as possible after
earthworks have been completed, or alternatively, within 14 days of the
cessation of earthworks, where practicable.
In the event of rain or at any time when rainstorms are likely to
happen, exposed surfaces should be covered by tarpaulin or by other means. · All
drainage facilities and erosion and sediment control structures will be
regularly inspected and maintained to ensure proper and efficient operation
at all times and particularly following rainstorms. Deposited silt and grit will be removed
regularly and disposed of by spreading evenly over stable, vegetated areas. · Measures
will be taken to reduce the ingress of site drainage into excavations. If the excavation of trenches in wet
periods is necessary, they will be dug and backfilled in short sections
wherever practicable. Water pumped out
from trenches or foundation excavations will be discharged into storm drains
via silt removal facilities. · Open
stockpiles of construction materials (for example, aggregates, sand and fill
material) should be covered with tarpaulin or similar fabric during
rainstorms. Measures will be taken to
prevent the washing away of construction materials, soil, silt or debris into
any drainage system. · The
wheels of all vehicles leaving and entering the construction site shall be
washed to minimise the carry over of mud onto Sha Lo Tung Road and into the
water gathering grounds. Wheel wash
water shall be recycled and only discharged into the temporary drainage
system. · Manholes
(including newly constructed ones) will always be adequately covered and
temporarily sealed so as to prevent silt, construction materials or debris
being washed into the drainage system. · Precautions
to be taken at any time of year when rainstorms are likely, actions to 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 PN 1/94. Particular attention will be paid to the
control of silty surface runoff during storm events, especially for areas
located near steep slopes. · Oil
interceptors will be provided in the drainage system and regularly emptied to
prevent the release of oil and grease into the storm water drainage system
after accidental spillages. The oil interceptors should be
cleaned when the volume of oil amounts to 30% of the total volume of the oil
interceptor. The interceptor
will have a bypass to prevent flushing during periods of heavy rain. · The
sandtraps should be cleaned out when the volume of settled sediments amounts
to 10% of the total volume of the traps. |

· Good
management and control can prevent generation of significant amount 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:
i.
Segregation and storage of different
types of waste in different containers, skips or stockpiles to enhance reuse or
recycling of material and their proper disposal;
ii.
Encourage collection of aluminium cans
and waste paper by individual collectors during construction with separate
labelled bins being provided to allow the segregation of these wastes from
other general refuse generated by the workforce;
iii.
Any unused chemicals and those with
remaining functional capacity be recycled as far as possible;
iv.
Use of reusable non-timber formwork to
reduce the amount of C&D materials;
v.
Prior to disposal of construction waste,
wood, steel and other metals should be separated, to the extent practical for
re-use and/or recycling to reduce the quantity of waste to be disposed at
landfills;
vi.
Proper storage and site practices to
reduce the potential for damage or contamination of construction materials;
and

Plan and stock construction materials
carefully to reduce amount of waste generated and avoid unnecessary
generation of waste. |

· Good
management and control can prevent generation of significant amount 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:
i.
Segregation and storage of different
types of waste in different containers, skips or stockpiles to enhance reuse
or recycling of material and their proper disposal;
ii.
Encourage collection of aluminium cans
and waste paper by individual collectors during construction with separate
labelled bins being provided to allow the segregation of these wastes from
other general refuse generated by the workforce;
iii.
Any unused chemicals and those with
remaining functional capacity be recycled as far as possible;
iv.
Use of reusable non-timber formwork to
reduce the amount of C&D materials;
v.
Prior to disposal of construction waste,
wood, steel and other metals should be separated, to the extent practical for
re-use and/or recycling to reduce the quantity of waste to be disposed at
landfills;
vi.
Proper storage and site practices to
reduce the potential for damage or contamination of construction materials;
and
vii.
Plan and stock construction materials
carefully to reduce amount of waste generated and avoid unnecessary
generation of waste. |

Detailed
Engineering Design Avoiding Habitat and Vegetation Loss · The
preliminary Master Layout Plan minimised the impacts on the secondary
woodland and trees within the Development Site. The detailed engineering design should
adopt the principle of balancing the minimising loss of trees (therefore
secondary woodland) and ecological habitats with the visual impact of the Project. This has been demonstrated in the
preliminary Master Layout Plan which
preserved majority of the secondary woodland (in which only approximately
0.03 ha would be affected). Provision
of an additional 20 m wide non-building buffer between the Sha Lo Tung SSSI

of Sha Lo Tung Road Improvement in advance.
Before any construction works are undertaken within the Development
Site, the Sha Lo Tung Road should be improved with well designed drainage
systems. All of the construction
run-off will be collected by the temporary drainage system with sandtrap
(with sufficient capacity) and then discharged to the newly constructed

· Restricted
Earthworks to the Dry Season. Major
Earthworks within the Development Site will only be undertaken in the dry
season (November to March) in order to avoid the risk of construction runoff
reaching ecological sensitive areas.
With the implementation of this measure, the risk from excessive
construction runoff in the event of a heavy rainstorm could be
prevented. Major earthworks will be
strictly prohibited during the wet season to minimise any ecological risk to
the Sha Lo Tung Valley. |

· Adoption
of Construction Sequences. Given that
the Development Site is elongated in shape and hilly in nature, the
construction sequence should be well managed in order to limit the volume of
surface runoff and treated effluent generated on-site, in particular during
the wet season (works other than earthworks).
In order to limit the size of exposed area and volume of the surface
runoff, the construction activities will be carried out sequentially (phase
by phase and sub-area to sub-area) rather than in parallel (refer to Site
Formation Construction Sequence as shown in Figure 3.13
in the EIA Report). Such arrangement
will help ensure that no construction runoff will discharge into Sha Lo Tung
Stream. |

· Provision
of Temporary Drainage Channels. Peripheral
temporary drainage channels (special designed U-channel, like a “J” shape
will be used) should be constructed along low side of all of the works areas
within the Development Site prior to the commencement of the construction works
(refer to Figure 6.3 in the EIA Report). All of the construction run-off will be
collected by the temporary drainage system with a sufficient number of
sandtraps and oil interceptors and then discharged to the newly constructed
stormwater drainage system along the Sha Lo Tung Road. A sandtrap of large capacity is proposed to
connect between the temporary drainage system within the Development Site and
the newly constructed stormwater drains beneath the Sha Lo Tung Road. All surface runoff within the site will be
diverted to this sandtrap before it is discharged from the site. Due to the lower level at the surface water
collection point within the Development Site, the surface water within the
Site will be stored to temporary storage tank (after passing through
sandtrap) in which a submersible pump will operate to continuously pump the
surface runoff to the proposed sandtrap.
A spare submersible pump will be put in place in the storage tank for
contingency purpose. Dual power supply
or ring main supply and standby submersible pumps will also be provided to
prevent the occurrence of emergency discharge of surface runoff into nearby
SSSI and CA zones. In accordance with
Section 8.2.4 of Geotechnical Manual for Slopes, the design of temporary

· Separate
Temporary Drainage System for Natural Runoff.
The temporary drainage system
may not be able to handle high volume of natural hinterland surface runoff
from the surrounding hills during heavy rainfalls. The surface runoff from the Site could be
separated from the natural hinterland surface runoff by deployment of two
drainage systems. To cater for the
surface water running from the hinterland in particular at the southern end
to the low profile of the Site, a separate temporary drainage system
including catchpits and drainage pipes is proposed to direct the natural
surface runoff without any contamination due to site activities to north side
of the site (refer to Figure 6.3 in the EIA Report). |

· Erection
of Site Hoardings and Chain-link Fence with Seal. Site hoardings and chain-link fence will be
erected along the temporary drainage system enclosing the whole Development
Site (refer to Figures 6.3
& 6.4). The hoardings and chain-link fence should
be erected firmly attached to the channel (any gaps are to be filled and
cemented) in order to avoid any accidental spilling over the peripheral
channel to the nearby streams. All of
the excessive runoff due to heavy rainfall or overflow of sandtraps/ storage
tanks could be retained within the Site and avoid any accidental discharges
into the Sha Lo Tung Stream. The
erection of the hoardings and chain-link fence should avoid any additional
impacts to the existing trees. |

Vegetation
Transplantation · Bamboo
Orchid and Willow-leaved Camellia were identified as being of conservation
interest within the Development Site.
As a mitigation measure, the affected individuals (if confirmed as
necessary during detailed engineering design) will be transplanted to
suitable nearby habitats prior to the construction phase as far as
practicable. A detailed vegetation
survey on the plant species will be conducted within the Development Site by
a suitably qualified botanist/ ecologist to identify and record the affected
individuals prior to the commencement of site clearance works. The survey will also serve to identify any
other plants of conservation interest which may be present in the Development
Site (eg Viburnum hanceanum) which
also need transplanting. Feasibility
and suitability of transplanting the affected plant species will be carefully
studied and suitable receptor sites will be identified. A detailed transplantation proposal
providing information on transplantation methodology, recipient site,
implementation programme, watering requirement, post-transplantation
monitoring and personnel involved shall be submitted to and approved by EPD,
AFCD and District Lands Office.
Transplantation will be supervised by a suitably qualified botanist/
horticulturist. After transplantation,
monitoring will be undertaken to check the performance and health conditions
of the transplanted individuals on a weekly basis for the first month after
transplantation and on a monthly basis for an additional eleven months. Remedial actions will be discussed with EPD,
AFCD and District Lands Office in the event of unsuccessful transplantation. |

Good Site Practice · Erect
fences along the boundary of the works area before the commencement of works
to prevent vehicle movements, and encroachment of personnel, onto adjacent
areas in particular the Pat Sin Leng Country Park, Conservation Area and Sha
Lo Tung Valley (including Sha Lo Tung SSSI and streams); · Restrict
the number of workers within the Development Site during construction and
request workers do not enter the ecologically sensitive areas, such as the
Sha Lo Tung SSSI (unless necessary for the works to be undertaken in the
Ecological Reserve) during working hours, throughout the construction phase; · Regularly
check the work site boundaries to ensure that they are not breached and that
damage does not occur to surrounding areas in particular the Pat Sin Leng
Country Park, Conservation Area and Sha Lo Tung Valley (including Sha Lo Tung
SSSI and streams); · Reinstate
temporarily affected areas immediately after completion of construction
works, through on-site tree/shrub planting.
The tree/shrub species will be chosen with reference to those in the
surrounding area and/or Annex F2 in EIA Report; and, · No
night time construction works within the Development Site. |

Daily Stream
Monitoring · Daily
stream monitoring should be undertaken along Sha Lo Tung Stream next to the
Development Site (the stream monitoring section) as shown in Figure 12.2 in the EIA Report during the construction phase. No more than three weeks prior to the
commencement of the construction phase and the impact monitoring, a baseline
stream monitoring will be undertaken on three occasions (days) for a week. Within a week after the completion of the
construction works, a post-project stream monitoring will be carried out on
three occasions (days). · The
qualified person (Environmentalist/ Ecologist with at least 3 years relevant experience
in field surveys) should walk along the stream bank of the stream monitoring
section to identify the signs of the impact.
Stream photographic records at five fixed locations along the stream
should be established during baseline, impact and post-project monitoring. The stream photographic records should be
reviewed and compared so as to identify any daily changes of the stream
condition. Should any signs of the
impact observed during the stream monitoring and confirmed or suspected to be
related to the construction work activities, the construction works should be
halted immediately until the pollution source(s) can be identified. A Preliminary Daily Stream Monitoring
Checklist is presented in Annex C
of the EM&A Manual. · Should
any signs of the impact be observed during the stream monitoring, the actions
listed in the Event and Action Plan in Table 8.2 in this Manual should be
carried out. |

Biological
Monitoring · The
species composition and relative abundance of riparian vegetation, adult
odonate and fish communities along Sha Lo Tung perennial streams
(particularly in the proximity to the development site) and the wet abandoned
agricultural land are considered as biological indicators of the aquatic
habitat conditions. Any stream
pollution due to uncontrolled surface runoff from the proposed development
would influence the water quality of Sha Lo Tung perennial streams and / or pools
within the wet abandoned agricultural land at the northeast of but outside the
Development Site, and therefore also the associated floral and faunal
communities. · A
baseline biological monitoring for the riparian vegetation, adult odonate and
fish communities should be conducted once during the wet season and once
during the dry season along the Sha Lo Tung Stream and the wet abandoned
agricultural land (exact location refer to Figure 12.2
in the EIA report) prior to the
commencement of any construction works.
The species diversity, relative abundance and community structure of
the riparian vegetation, adult odonate and fishes should be recorded during
the monitoring. Riparian vegetation,
as well as the aquatic plants, encountered and their relative abundance will
be recorded with special attention to the signs of pollution, ie mud, observed
on the leave surface. Adult odonate
(with particular focus on stream specialists) will be surveyed using the
transect count method (Figure 12.2 in the EIA Report). Any adult odonate within 10 m from either
side of the survey transect (stream monitoring section as shown in Figure 12.2 in the EIA Report) will be identified and counted. The fishes (with particular focus on Hong
Kong Paradise Fish, Small Snakehead and Predaceous Chub) will be surveyed of
by direct observation and active searching/ trapping if necessary. The fishes encountered and their relative
abundance will be recorded along the stream monitoring section. The biological monitoring shall be
conducted by experienced ecologist(s) of more than 3 years experience on
riparian vegetation, adult odonate and fish communities. · The impact
biological monitoring for the riparian vegetation, adult odonate and fish
communities should be conducted biweekly through out the construction
period. Baseline and impact monitoring
data, in particular the species composition, diversity and relative
abundance, should be compared, any substantial differences in habitat
characteristics (e.g., water quality, riparian and aquatic vegetation) and
the seasonality of the fauna should be noted.
· Operational
monitoring, following the methodology of the baseline stream hydrology and
biological monitoring, should be conducted quarterly within the first three
years after the completion of construction works (a total twelve
occasions). Remedial actions will be
discussed with the EPD and AFCD in the event of a change in stream hydrology
(ie less stream flow) or decline in species diversity and relative abundance
of adult dragonflies and fishes. Seasonal
changes should be taken into account in identifying the change in stream
hydrology (ie reduction in stream flow) or decline in species diversity and
relative abundance of adult dragonflies and fishes). |

0.2 ha due to the Sha Lo Tung Road Improvement) and plantation (approximately 0.43 ha due to
the Sha Lo Tung Road Improvement). The
compensatory planting will be planted on-site, within the Development Site and
the Ecological Reserve. The concept of
the proposed compensatory planting at the Development Site is presented in Figures 10.5a-c in the EIA Report. The proposed
planting area within the Ecological Reserve is recommended in
grassland shrubland mosaic to the north of Lei Uk and the northeast of the
Development Site (refer to Figures 9.2 and 10.5b in the EIA
Report). It should be noted that the location and
size of the compensatory planting should be approved by AFCD and EPD. The selection of planting species shall be
made with reference to the species identified in Annex F2 in the EIA Report and be native to Hong Kong or the South
China region. The arrangement of the
on-site compensatory planting, i.e. tree/ shrub mix and exact location, will

· Provision
of Temporary Drainage Channels. To
prevent the discharge of silty surface run-off to the existing watercourse,
an effective temporary drainage system will be introduced for the road improvement
work. Prior to the construction,
temporary hoarding will be erected and sandbags be placed at the toe of the
hoarding within the works site (refer to Figures 6.3 & 6.4 in the EIA Report) to prevent any silty water
flowing out of the works site. As
shown in Figure 3.22
in the EIA Report, at least two temporary sandtraps connecting with temporary
surface drainage will be proposed at each phase of road improvement works
(except Phase 3) prior to discharging into the nearest watercourse to avoid any
excessive sediment or blockage of existing natural drainage system. Similar to the construction activities
within the Development Site, all of the surface run-off generated along the
section close to Sha Lo Tung Valley (approximately half of the Phase 3) will
be collected by the temporary drainage system with a sufficient number of
sandtraps (with sufficient capacity) and then discharged to the newly
constructed stormwater drainage system along the improved Sha Lo Tung Road. A sandtrap is proposed to connect between
the temporary drainage system within the Development Site and the newly
constructed stormwater drains beneath the Sha Lo Tung Road. All surface runoff within the site will be
diverted to this sandtrap before it is discharged from the site. Due to the lower level at the surface water
collection point within the Development Site, the surface water within the
Site will be stored in temporary storage tanks (after passing through
sandtraps) in which a submersible pump will operate to continuously pump the
surface runoff to the proposed sandtrap.
A spare submersible pump will be put in place in the storage tank for
contingency purpose. |

A detailed vegetation survey on these plant species will be conducted
along the Sha Lo Tung Road by a suitably qualified botanist/ ecologist to
identify and record the affected individuals prior to the commencement of
site clearance works. The survey will
also serve to identify any other plants of conservation interest which may be
present in along the Sha Lo Tung road (eg Viburnum
hanceanum) which also need transplanting.
Feasibility and suitability of transplanting the affected plant
species will be carefully studied and suitable receptor sites will be
identified. Detailed transplantation

· If laying of drainage
pipes is considered necessary adjacent to LF01, it is recommended that the
construction method be reviewed to avoid and minimise potential construction
vibration impact to LF01. If potential
construction vibration is considered unavoidable, a vibration monitoring
should be conducted by the construction contractor during the construction
work adjacent to LF01. The monitoring
should include:
i.
A pre-condition survey for LF01 conducted by a structural
engineer to record the state of the feature (including all cracks) before
construction work commences;
ii.
Trial test of vibration generated from ground borne
vibration related works;
iii.
Evaluation and review of the construction method to avoid
and minimise the potential impact; and
iv.
Recommendation of vibration monitoring and protection
measures. This would include the
establishment of a vibration limit, monitoring frequency and protective
measures to be agreed with the Engineer and AMO. · In addition, during the
construction stage of the Sha Lo Tung Road Improvement adjacent to LF01, the
construction contractor should ensure visitors’ safe access to the
shrine. A temporary fence with access
entrance should be erected to prevent any direct impact to LF01 during the
construction work. |
