Air
Quality
The impact
monitoring had been carried out in accordance with section 5.8 of the approved
EM&A Manual to determine the 1-hour and 24-hour total suspended
particulates (TSP) levels at the monitoring locations in the reporting month.
The sampling
frequency of at least once in every 6 days, shall be strictly observed at the
monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring, the
sampling frequency of at least 3 times in every 6 days should be undertaken
when the highest dust impact occurs.
General
meteorological conditions (wind speed, direction and precipitation) and notes
regarding any significant adjacent dust producing sources had also been
recorded throughout the impact monitoring period.
Noise
Construction noise
level shall be measured in terms of the A-weighted equivalent continuous sound
pressure level (Leq). Leq (30min) shall be used as the monitoring
parameter for the time period between 0700 and 1900 hours on normal weekdays.
For all other time
periods, Leq (5min) shall be employed for comparison with the Noise Control
Ordinance (NCO) criteria.
As supplementary
information for data auditing, statistical results such as L10 and L90
shall also be obtained for reference.
Air Quality
1-hour TSP levels
and 24-hour TSP had been measured with direct reading dust meter and High
Volume Samplers respectively. It has been demonstrated its capability in achieving
comparable results with high volume sampling method as set out in the Title 40
of the Code of Federal Regulations, Chapter 1 (Part 50).
The 1-hour TSP
meter was calibrated by the manufacturer prior to purchasing. Zero response of
the instrument was checked before and after each monitoring event.
Operation of the 1-hour TSP meter followed manufacturer’s Operation and Service
Manual. The 24-hour TSP meter was calibrated against firmware 80570-8100-V1.0.4,
annually. Operation of the 24-hour TSP meter followed manufacturer’s Operation
and Service Manual. Valid calibration
certificates of dust monitoring equipment are attached in Appendix H.
A summary of the
equipment that was deployed for the 24- hour averaged monitoring is shown in

Methodology and QA/QC results
Air
Quality
The 1-hour TSP
monitor, portable dust meters (Sibata Digital Dust Indicator Model LD-5R and
PC-3A(E) digital dust indicator) were used for the impact monitoring. The
1-hour TSP meters provides a real time 1-hour TSP measurement based on 90o
light scattering. Three 1-hour TSP level were logged per every six days.
The 24-hour TSP
monitor, High Volume Samplers (Tisch TE-5170X High Volume Air Sampler) were
used for the impact monitoring. The 24-hour TSP monitoring consists of the
following:
u The HVS
was set at the monitoring location, with electricity supply connected and
secured;
u HVS was
calibrated before commencing the 1st measurement;
u The filter
paper was weight and provided by HOKLAS lab (Acumen Laboratory and Testing
Limited and ALS Technichem (HK) Pty Ltd) before and after the sampling.
Certificate of HOKLAS accredited laboratory can be referred to Appendix J;
u The
airflow over time during sampling process was recorded by the HVS.
HVSs were free-standing with no obstruction. The following
criteria were considered in the installation of the HVS:
u Appropriate
support to secure the samples against gusty wind needed to be provided the monitoring
station;
u A
minimum of 2m separation from walls, parapets and penthouses was required for
rooftop samplers;
u No
furnace or incinerator flues was nearby;
u Airflow
around the sampler was unrestricted; and
u Permission
could be obtained to set up the samplers and gain access to the monitoring
station.
u Glass
fiber filters were labelled and sufficient filters that were clean and without
pinholes were selected;
u All filters
were equilibrated in the conditioning environment for 24 hours before weighing.
The conditioning environment temperature was around 25℃ and not varied by
more than ±3℃; the relative humidity (RH)was 40%; and
u Acumen
Laboratory and Testing Limited and ALS Technichem (HK) Pty Limited, as HOKLAS
accredited laboratory, implemented comprehensive quality assurance and quality
control programmes on the filters.
u The power
supply was checked to ensure that the HVS was working properly;
u The
filter holder and area surrounding the filter were cleaned;
u The
filter holder was removed by loosening the foul bolts and a new filter, with
stamped number upward, on a supporting screen was aligned carefully;
u The
filter was properly aligned on the screen so that the gasket formed an airtight
seal on the outer edges of the filter;
u The
swing bolts were fastened to hold the filter holder down to the frame. The pressure
applied should be sufficient to avoid air leakage at the edges;
u The
shelter lid was closed and secured with an aluminum strip;
u The HVS
was warmed- up for about 5 minutes to establish run- temperature conditions;
u A new
flow rate record sheet was inserted into the flow recorder;
u The
flow rates of the HVS was checked and adjusted to between 0.62-1.30m3min-1,
which was within the range specified in the EM&A Manual (i.e. 0.6- 1.7m3min-1);
u The programmable
timer was set for a sampling period of 24 hours, and the starting time, weather
condition and filter number were recorded;
u The
initial elapsed time was recorded;
u At the
end of sampling, the sampled filter was removed carefully and folded in half so
that only surfaces with collected particulate matter were in contact;
u The
filter paper was placed in a clean plastic envelope and sealed; all monitoring
information was recorded on a standard data sheet and
u The filters
were sent to (Acumen Laboratory and Testing Ltd and ALS Technichem (HK) Pty
Ltd) for analysis.
u The HVS
and their accessories were maintained in a good working condition. For example,
motor brushes were replaced routinely and electrical wiring was checked to
ensure a continuous power supply; and
u The
flow rate of each HVS with mass flow controller was calibrated using an orifice
calibrator, Initial calibrations of the dust monitoring equipment were conducted
upon installation and prior to commissioning. Five- point calibration was
carried out for HVS using TE-5025A and TE-5028A Calibration Kit. HVS is
calibrated bimonthly. The calibration records for the HVS is given in Appendix
H.
u The
wind speed has been recorded from Hong Kong Observatory- King’s Park
meteorological station, along with portable wind speed meter stand by as back
up when the information are not available from HKO.
Noise
All noise
measurements by the meter were set to FAST response and on the A-weighted
equivalent continuous sound pressure level (Leq) in decibels dB(A).
LAeq(30min) was used as the monitoring metric for the time period
between 0700 –1900 hours on normal weekdays. The measured noise levels were
logged every 5 minutes throughout the monitoring period.
Prior to the noise
measurement, the accuracy of the sound level meter was checked using an
acoustic calibrator generating a known sound pressure level at a known frequency.
Checking was conducted before and after the monitoring. The calibration level
before and after the noise measurement is agreed to within 1.0 dB(A).
Noise measurements
should not be made in presence of fog, rain, wind with a steady speed exceeding
5 ms-1 or wind with gusts exceeding 10 ms-1. The wind
speed was checked with a portable wind speed meter capable of measuring with
speeds in ms-1.
Air Quality
During the site
visit, both of the original proposed dust monitoring locations were rejected
due to the condition at The Coronation was not favourable for monitoring and
the access was declined by the management office of Hong Kong Community College
(HKCC) of PolyU. Two alternative air monitoring stations Yau Ma Tei Catholic
Primary School (Hoi Wang Road) and Man Cheong Building had been proposed by ET
and approved by IEC. 2 designated air monitoring locations were identified and
agreed with IEC and EPD. Details of air monitoring stations are described in
Table 3.3. The location plan of air quality monitoring stations is shown in

The waste generated from this Project includes inert
C&D materials, and non-inert C&D materials. Non-inert C&D materials
are made up of general refuse, vegetative wastes and recyclable wastes such as
plastics and paper/cardboard packaging waste. Steel materials generated from
the project are also grouped into non-inert C&D materials as the materials
were not disposed of with other inert C&D materials. With reference to
relevant handling records and trip tickets of this Project, the quantities of
different types of waste generated in the reporting month are summarised in
Table 3.11. Details of cumulative waste management data are
presented as a waste flow table in Appendix N.

S6.9.1.1 |
W1 |
In accordance with the Practice Note for Professional Persons on
Construction Site Drainage, Environmental Protection Department, 1994 (ProPECC
PN1/94), construction phase mitigation measures shall include the following: Construction Runoff · 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 (both temporary and permanent drainage pipes and
culverts), earth bunds or sand bag barriers should be provided on site to
direct stormwater to silt removal facilities. The design of the
temporary on-site drainage system will be undertaken by the contractor prior
to the commencement of construction; · The dikes or embankments for flood protection should be
implemented around the boundaries of earthwork areas. Temporary ditches
should be provided to facilitate the runoff discharge into an appropriate
watercourse, through a silt/ sediment trap. The sediment/ silt traps
should be incorporated in the permanent drainage channels to enhance
deposition rates; · The design of efficient silt removal facilities should be based
on the guidelines in Appendix A1 of ProPECC PN 1/94, which states that the
retention time for silt/ sand traps should be 5 minutes under maximum flow
conditions. Sizes may vary depending upon the flow rate, but for a flow
rate of 0.1 m3/s a sedimentation basin of 30 m3 would be required and for a
flow rate of 0.5 m3/s the basin would be 150 m3. The detailed design of
the sand/ silt traps shall be undertaken by the contractor prior to the
commencement of construction; · All exposed earth areas should be completed and vegetated as
soon as possible after earthworks have been completed, or alternatively,
within 14 days of the cessation of earthworks where practicable.
Exposed slope surfaces should be covered by tarpaulin or other means; · The overall slope of the site should be kept to a minimum to reduce
the erosive potential of surface water flows, and all traffic areas and
access roads protected by coarse stone ballast. An additional advantage
accruing from the use of crushed stone is the positive traction gained during
prolonged periods of inclement weather and the reduction of surface sheet
flows; · 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 following rainstorms. Deposited
silt and grit should be removed regularly and disposed of by spreading evenly
over stable, vegetated areas; · Measures should be taken to minimize the ingress of site
drainage into excavations. If the excavation of trenches in wet periods
is necessary, they should be dug and backfilled in short sections wherever
practicable. Water pumped out from trenches or foundation excavations
should be discharged into storm drains via silt removal facilities; · Open stockpiles of construction materials (for example,
aggregates, sand and fill material) of more than 50m3 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 should always be adequately covered and temporarily sealed
so as to prevent silt, construction materials or debris being washed into the
drainage system and storm runoff being directed into foul sewers; · Precautions 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 summarized in Appendix A2
of ProPECC 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; · 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 site wheel washing
facilities should be provided at every construction site exit where
practicable. Wash-water should have sand and silt settled out and
removed at least on a weekly basis 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; · Oil interceptors should be provided in the drainage system
downstream of any oil/ fuel pollution sources. The oil interceptors
should be emptied and cleaned regularly to prevent the release of oil and
grease into the storm water drainage system after accidental spillage.
A bypass should be provided for the oil interceptors to prevent flushing
during heavy rain; · Construction solid waste, debris and rubbish on site should be
collected, handled and disposed of properly to avoid water quality impacts; · All fuel tanks and storage areas should be provided with locks and
sited on sealed areas, within bunds of a capacity equal to 110% of the
storage capacity of the largest tank to prevent spilled fuel oils from
reaching water sensitive receivers nearby; · Adopt best management practices; · All earth works should be conducted sequentially to limit the
amount of construction runoff generated from exposed areas during the wet
season (April to January) as far as practicable. |

Tunneling Works and Underground Works · Cut-&-cover tunneling work should be conducted sequentially
to limit the amount of construction runoff generated from exposed areas
during the wet season (April to January) as far as practicable. · Uncontaminated discharge should pass through sedimentation tanks
prior to off-site discharge; · The wastewater with a high concentration of SS should be treated
(e.g. by sedimentation tanks with sufficient retention time) before
discharge. Oil interceptors would also be required to remove the oil,
lubricants and grease from the wastewater; · Direct discharge of the bentonite slurry (as a result of D-wall)
is not allowed. It should be reconditioned and reused wherever
practicable. Temporary storage locations (typically a properly closed
warehouse) should be provided on site for any unused bentonite that needs to
be transported away after all the related construction activities area
completed. The requirements in ProPECC PN 1/94 should be adhered to in
the handling and disposal of bentonite slurries. |

Groundwater from Potential Contaminated Area: · No direct discharge of groundwater from contaminated areas
should be adopted. · A discharge license under the WPCO through the Regional Office
of EPD for groundwater discharge should be applied. Prior to the excavation
works within these potentially contaminated areas, the groundwater quality
should be reviewed during the process of discharge license application. The
compliance to the Technical Memorandum on Standards for Effluents Discharged
into Drainage on Sewerage Systems, Inland and Coastal Waters (TM-DSS) and the
existence of prohibited substance should be confirmed. If the review results
indicated that the groundwater to be generated from the excavation works
would be contaminated, the contaminated groundwater should be either properly
treated in compliance with the requirements of the TM-DSS or properly
recharged into the ground. · If wastewater treatment is deployed, the wastewater treatment
unit shall deploy suitable treatment process (e.g. oil interceptor /
activated carbon) to reduce the pollution level to an acceptable standard and
remove any prohibited substances (e.g. TPH) to undetectable range. All
treated effluent from wastewater treatment plant shall meet the requirements
as stated in TM-DSS and should be discharged into the foul sewers. · If groundwater recharging wells are deployed, recharging wells should
be installed as appropriate for recharging the contaminated groundwater back
into the ground. The recharging wells should be selected at places where the
groundwater quality will not be affected by the recharge operation as
indicated in the Section 2.3 of TM-DSS. The baseline groundwater quality
shall be determined prior to the selection of the recharge wells, and submit
a working plan (including the laboratory analytical results showing the
quality of groundwater at the proposed recharge location(s) as well as the
pollutant levels of groundwater to be recharged) to EPD for agreement.
Pollution levels of groundwater to be recharged shall not be higher than
pollutant levels of ambient groundwater at the recharge well. Prior to
recharge, any prohibited substances such as TPH products should be removed as
necessary by installing the petrol interceptor. |

On-site sorting of C&D material · Geological assessment should be carried out by competent persons
on site during excavation to identify materials which are not suitable to use
as aggregate in structural concrete (e.g. volcanic rock, Aplite dyke rock,
etc.). Volcanic rock and Aplite dyke rock should be separated at the
source sites as far as practicable and stored at designated stockpile area
preventing them from delivering to crushing facilities. The crushing
plant operator should also be reminded to set up measures to prevent
unsuitable rock from ending up at concrete batching plants and be turned into
concrete for structural use. Details regarding control measures at
source site and crushing facilities should be submitted by the Contractor for
the Engineer to review and agree. In addition, site records should also
be kept for the types of rock materials excavated and the traceability of
delivery will be ensured with the implementation of Trip Ticket System and
enforced by site supervisory staff as stipulated under DEVB TC(W) No. 6/2010
for tracking of the correct delivery to the rock crushing facilities for
processing into aggregates. Alternative disposal option for the reuse
of volcanic rock and Aplite Dyke rock, etc. should be explored. |

use of recycled aggregates where appropriate; · Adopt ‘selective demolition’ technique to demolish the existing
structures and facilities with a view to recovering broken concrete
effectively for recycling purpose, where possible; · Implement a trip-ticket system for each works contract to ensure
that the disposal of C&D materials are properly documented and verified;
and · Implement an enhanced Waste Management Plan similar to ETWBTC (Works)
No. 19/2005 – “Environmental Management on Construction Sites” to encourage
on-site sorting of C&D materials and to minimize their generation during

C&D Waste · Standard formwork or pre-fabrication should be used as far as
practicable in order to minimize the arising of C&D materials. The
use of more durable formwork or plastic facing for the construction works
should be considered. Use of wooden hoardings should not be used, as in
other projects. Metal hoarding should be used to enhance the
possibility of recycling. The purchasing of construction materials will
be carefully planned in order to avoid over ordering and wastage; · The Contractor should recycle as much of the C&D materials
as possible on-site. Public fill and C&D waste should be segregated and
stored in different containers or skips to enhance reuse or recycling of
materials and their proper disposal. Where practicable, concrete and
masonry can be crushed and used as fill. Steel reinforcement bar can be
used by scrap steel mills. Different areas of the sites should be
considered for such segregation and storage. |

being released into the water column or deposited in the locations other than
designated location; · All vessels shall be sized such that adequate draft 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; · Before moving the vessels which are used for transporting
dredged material, excess material shall be cleaned from the decks and exposed
fittings of vessels and the excess materials shall never be dumped into the
sea except at the approved locations; · Adequate freeboard shall be maintained on barges to ensure that
decks are not washed by wave action. · The Contractors shall monitor all vessels transporting material
to ensure that no dumping outside the approved location takes place. The
Contractor shall keep and produce logs and other records to demonstrate
compliance and that journeys are consistent with designated locations and copies
of such records shall be submitted to the engineers; · The Contractors shall comply with the conditions in the dumping
license. · All bottom dumping vessels (Hopper barges) shall be fitted with
tight fittings seals to their bottom openings to prevent leakage of material; · The material shall be placed into the disposal pit by bottom
dumping; · Contaminated marine mud shall be transported by spit barge of
not less than 750m3 capacity and capable of rapid opening and discharge at
the disposal site; · Discharge shall be undertaken rapidly and the hoppers shall be
closed immediately. Material adhering to the sides of the hopper shall not be
washed out of the hopper and the hopper shall remain closed until the barge
returns to the disposal site. · For Type 3 special disposal treatment, sealing of contaminant
with geosynthetic containment before dropping designated mud pit would be a
possible arrangement. A geosynthetic containment method is a method whereby
the sediments are sealed in geosynthetic containers and, the containers would
be dropped into the designated contaminated mud pit where they would be
covered by further mud disposal and later by the mud pit capping at the disposal
site, thereby fulfilling the requirements for fully confined mud disposal. |

of Chemical Wastes; · Containers used for the storage of chemical wastes should be
suitable for the substance they are holding, resistant to corrosion,
maintained in a good condition, and securely closed, have a capacity of less than
450 L unless the specification has been approved by EPD, and display a label
in English and Chinese in accordance with instructions prescribed in Schedule
2 of the regulation; · The storage area for chemical wastes should be clearly labelled
and used solely for the storage of chemical waste, enclosed on at least 3
sides, have an impermeable floor and bunding of sufficient capacity to
accommodate 110% of the volume of the largest container or 20% of the total volume
of waste stored in that area, whichever is the greatest, have adequate
ventilation, covered to prevent rainfall entering, and arranged so that
incompatible materials are adequately separated; · Disposal of chemical waste should be via a licensed waste
collector, be to a facility licensed to receive chemical waste, such as the
Chemical Waste Treatment Centre which also offers a chemical waste collection
service and can supply the necessary storage containers, or be to a reuser of
the waste, under approval from EPD. |

In
accordance with the Practice Note for Professional Persons on Construction
Site Drainage, Environmental Protection Department, 2023 (ProPECC PN 2/23),
construction phase mitigation measures shall include the following: Construction
Runoff · 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 (both temporary
and permanent drainage pipes and culverts), earth bunds or sandbag barriers
should be provided on site to direct stormwater to silt removal
facilities. The design of the temporary on-site drainage system will be
undertaken by the contractor prior to the commencement of construction; · The dikes or
embankments for flood protection should be implemented around the boundaries
of earthwork areas. Temporary ditches should be provided to facilitate
the runoff discharge into an appropriate watercourse, through a silt/
sediment trap. The sediment/ silt traps should be incorporated in the
permanent drainage channels to enhance deposition rates; · The design of
efficient silt removal facilities should be based on the guidelines in
Appendix A1 of ProPECC PN 2/23, which states that the retention time for
silt/ sand traps should be 5 minutes under maximum flow conditions.
Sizes may vary depending upon the flow rate, but for a flow rate of 0.1 m3/s
a sedimentation basin of 30 m3 would be required and for a flow
rate of 0.5 m3/s the basin would be 150 m3. The
detailed design of the sand/ silt traps shall be undertaken by the contractor
prior to the commencement of construction; · All exposed earth
areas should be completed and vegetated as soon as possible after earthworks
have been completed, or alternatively, within 14 days of the cessation of
earthworks where practicable. Exposed slope surfaces should be covered
by tarpaulin or other means; · The overall slope
of the site should be kept to a minimum to reduce the erosive potential of
surface water flows, and all traffic areas and access roads protected by
coarse stone ballast. An additional advantage accruing from the use of
crushed stone is the positive traction gained during prolonged periods of
inclement weather and the reduction of surface sheet flows; · 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 following rainstorms. Deposited silt and grit
should be removed regularly and disposed of by spreading evenly over stable,
vegetated areas; · Measures should
be taken to minimize the ingress of site drainage into excavations. If
the excavation of trenches in wet periods is necessary, they should be dug
and backfilled in short sections wherever practicable. Water pumped out
from trenches or foundation excavations should be discharged into storm
drains via silt removal facilities; · Open stockpiles
of construction materials (for example, aggregates, sand and fill material)
of more than 50m3 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 should
always be adequately covered and temporarily sealed so as to prevent silt,
construction materials or debris being washed into the drainage system and
storm runoff being directed into foul sewers; · Precautions 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 summarized in Appendix A2 of ProPECC PN 2/23.
Particular attention should be paid to the control of silty surface runoff
during storm events, especially for areas located near steep slopes; · 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 site wheel washing facilities should be provided at
every construction site exit where practicable. Wash-water should have
sand and silt settled out and removed at least on a weekly basis 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; · Oil interceptors
should be provided in the drainage system downstream of any oil/ fuel
pollution sources. The oil interceptors should be emptied and cleaned
regularly to prevent the release of oil and grease into the storm water
drainage system after accidental spillage. A bypass should be provided
for the oil interceptors to prevent flushing during heavy rain; · Construction
solid waste, debris and rubbish on site should be collected, handled and
disposed of properly to avoid water quality impacts; · All fuel tanks
and storage areas should be provided with locks and sited on sealed areas,
within bunds of a capacity equal to 110% of the storage capacity of the
largest tank to prevent spilled fuel oils from reaching water sensitive
receivers nearby; · Adopt best
management practices; · All earth works
should be conducted sequentially to limit the amount of construction runoff
generated from exposed areas during the wet season (April to September) as
far as practicable. |

Tunnelling
Works and Underground Works · Cut-&-cover
tunnelling work should be conducted sequentially to limit the amount of construction
runoff generated from exposed areas during the wet season (April to
September) as far as practicable. · Uncontaminated
discharge should pass through sedimentation tanks prior to off-site
discharge; · The wastewater
with a high concentration of SS should be treated (e.g. by sedimentation
tanks with sufficient retention time) before discharge. Oil
interceptors would also be required to remove oil, lubricants and grease from
the wastewater; · Direct discharge
of the bentonite slurry (as a result of D-wall) is not allowed. It
should be reconditioned and reused wherever practicable. Temporary
storage locations (typically a properly closed warehouse) should be provided
on site for any unused bentonite that needs to be transported away after all
the related construction activities area completed. The requirements in
ProPECC PN 2/23 should be adhered to in the handling and disposal of
bentonite slurries. |

Groundwater
from Potential Contaminated Area: · No direct
discharge of groundwater from contaminated areas should be adopted. · A discharge
license under the WPCO through the Regional Office of EPD for groundwater
discharge should be applied. Prior to the excavation works within these
potentially contaminated areas, the groundwater quality should be reviewed
during the process of discharge license application. The compliance to the
Technical Memorandum on Standards for Effluents Discharged into Drainage on
Sewerage Systems, Inland and Coastal Waters (TM-DSS) and the existence of
prohibited substance should be confirmed. If the review results indicated
that the groundwater to be generated from the excavation works would be
contaminated, the contaminated groundwater should be either properly treated
in compliance with the requirements of the TM-DSS or properly recharged into
the ground. · If wastewater
treatment is deployed, the wastewater treatment unit shall deploy suitable
treatment process (e.g. oil interceptor / activated carbon) to reduce the
pollution level to an acceptable standard and remove any prohibited
substances (e.g. TPH) to undetectable range. All treated effluent from
wastewater treatment plant shall meet the requirements as stated in TM-DSS
and should be discharged into the foul sewers. · If groundwater
recharging wells are deployed, recharging wells should be installed as
appropriate for recharging the contaminated groundwater back into the ground.
The recharging wells should be selected at places where the groundwater
quality will not be affected by the recharge operation as indicated in the
Section 2.3 of TM-DSS. The baseline groundwater quality shall be determined
prior to the selection of the recharge wells, and submit a working plan
(including the laboratory analytical results showing the quality of
groundwater at the proposed recharge location(s) as well as the pollutant
levels of groundwater to be recharged) to EPD for agreement. Pollution levels
of groundwater to be recharged shall not be higher than pollutant levels of
ambient groundwater at the recharge well. Prior to recharge, any prohibited
substances such as TPH products should be removed as necessary by installing the
petrol interceptor. |

On-site
sorting of C&D material · Geological
assessment should be carried out by competent persons on site during
excavation to identify materials which are not suitable to use as aggregate
in structural concrete (e.g. volcanic rock, Aplite dyke rock, etc.).
Volcanic rock and Aplite dyke rock should be separated at the source sites as
far as practicable and stored at designated stockpile area preventing them
from delivering to crushing facilities. The crushing plant operator
should also be reminded to set up measures to prevent unsuitable rock from
ending up at concrete batching plants and be turned into concrete for
structural use. Details regarding control measures at source site and
crushing facilities should be submitted by the Contractor for the Engineer to
review and agree. In addition, site records should also be kept for the
types of rock materials excavated and the traceability of delivery will be
ensured with the implementation of Trip Ticket System and enforced by site
supervisory staff as stipulated under DEVB TC(W) No. 6/2010 for tracking of
the correct delivery to the rock crushing facilities for processing into
aggregates. Alternative disposal option for the reuse of volcanic rock
and Aplite Dyke rock, etc. should be explored. |

Waste · Standard
formwork or pre-fabrication should be used as far as practicable in order to
minimize the arising of C&D materials. The use of more durable
formwork or plastic facing for the construction works should be
considered. Use of wooden hoardings should not be used, as in other
projects. Metal hoarding should be used to enhance the possibility of
recycling. The purchasing of construction materials will be carefully
planned in order to avoid over ordering and wastage; · The
Contractor should recycle as much of the C&D materials as possible
on-site. Public fill and C&D waste should be segregated and stored in
different containers or skips to enhance reuse or recycling of materials and
their proper disposal. Where practicable, concrete and masonry can be
crushed and used as fill. Steel reinforcement bar can be used by scrap
steel mills. Different areas of the sites should be considered for such
segregation and storage. |

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; · Before
moving the vessels which are used for transporting dredged material, excess
material shall be cleaned from the decks and exposed fittings of vessels and
the excess materials shall never be dumped into the sea except at the
approved locations; · Adequate
freeboard shall be maintained on barges to ensure that decks are not washed
by wave action. · The
Contractors shall monitor all vessels transporting material to ensure that no
dumping outside the approved location takes place. The Contractor shall keep
and produce logs and other records to demonstrate compliance and that
journeys are consistent with designated locations and copies of such records
shall be submitted to the engineers; · The
Contractors shall comply with the conditions in the dumping license. · All
bottom dumping vessels (Hopper barges) shall be fitted with tight fittings
seals to their bottom openings to prevent leakage of material; · The
material shall be placed into the disposal pit by bottom dumping; · Contaminated
marine mud shall be transported by spit barge of not less than 750m3
capacity and capable of rapid opening and discharge at the disposal site; · Discharge
shall be undertaken rapidly, and the hoppers shall be closed immediately.
Material adhering to the sides of the hopper shall not be washed out of the
hopper and the hopper shall remain closed until the barge returns to the
disposal site. · For
Type 3 special disposal treatment, sealing of contaminant with geosynthetic
containment before dropping designated mud pit would be a possible
arrangement. A geosynthetic containment method is a method whereby the
sediments are sealed in geosynthetic containers and, the containers would be
dropped into the designated contaminated mud pit where they would be covered
by further mud disposal and later by the mud pit capping at the disposal
site, thereby fulfilling the requirements for fully confined mud disposal. |

General
Refuse · General refuse
generated on-site should be stored in enclosed bins or compaction units
separately from construction and chemical wastes; · A reputable waste
collector should be employed by the Contractor to remove general refuse from
the site, separately from construction and chemical wastes, on a daily basis
to minimize odour, pest and litter impacts. Burning of refuse on
construction sites is prohibited by law. · Aluminium cans
are often recovered from the waste stream by individual collectors if they
are segregated and made easily accessible. Separate labelled bins for
their deposit should be provided if feasible; · Office wastes can
be reduced through the recycling of paper if volumes are large enough to
warrant collection. Participation in a local collection scheme should
be considered by the Contractor. |

Screen Planting · Tall
screen/buffer trees, shrubs and climbers should be planted, in so far as is
possible, to soften and screen proposed structures such as roads and central
strip, vertical edges and buildings and to enhance streetscape greening
effect where appropriate. Indiscriminate use of trees for screening must be
avoided and the principle of ‘right tree for the right place’ must be
followed. This detail will be provided at the Detailed Design stage. This
measure may additionally form part of the compensatory planting and will
improve and create a pleasant pedestrian environment. |
