Note: (1)
The air monitoring station proposed in the EM&A Manual
(i.e. Wyler Gardens with ID: E-A14) was not available for impact dust
monitoring, therefore impact monitoring was conducted at E-A14a as an
alternative which was agreed by the ER, IEC and EPD. |
||
-
A horizontal platform with
appropriate support to secure the sampler against gusty wind was provided.
-
Two samplers should not be
placed less than 2m apart from each other.
-
The distance between the
HVS and any obstacles, such as buildings, was at least twice the height that
the obstacle protrudes above the HVS.
-
A minimum of 2 meters separation
from walls, parapets and penthouse for rooftop sampler.
-
A minimum of 2 meters
separation from any supporting structure, measured horizontally is required.
-
No furnace or incinerator
flues nearby.
-
Airflow around the sampler
was unrestricted.
-
The sampler was located
more than 20 meters from any dripline.
-
Any wire fence and gate,
required to protect the sampler, did not obstruct the monitoring process.
-
Permission was obtained to
set up the samplers and access to the monitoring station.
-
A secured supply of
electricity was obtained to operate the sampler.
·
Preparation of Filter
Paper
-
Glass fibre filters, G810
were labelled and sufficient filters that were clean and without pinholes were
selected.
-
All filters were
equilibrated in the conditioning environment for 24 hours before weighing. The
conditioning environment temperature was around 25 °C and not variable by more
than ±3 °C; the relative humidity (RH) was < 50% and not variable by more than
±5%. A convenient working RH was 40%.
-
All filter papers were
prepared and analysed by Acumen Laboratory and Testing Limited and ALS Technichem (HK) Pty Limited, which is a HOKLAS accredited
laboratory and has comprehensive quality assurance and quality control
programmes.
·
Field Monitoring
-
The power supply was
checked to ensure the HVS works properly.
-
The filter holder and the
area surrounding the filter were cleaned.
-
The filter holder was
removed by loosening the four bolts and a new filter, with stamped number
upward, on a supporting screen was aligned carefully.
-
The filter was properly
aligned on the screen so that the gasket formed an airtight seal on the outer
edges of the filter.
-
The swing bolts were
fastened to hold the filter holder down to the frame. The pressure applied was
sufficient to avoid air leakage at the edges.
-
Then the shelter lid was
closed and was secured with the aluminium strip.
-
The HVS was warmed-up for
about 5 minutes to establish run-temperature conditions.
-
A new flow rate record
sheet was set into the flow recorder.
-
On site temperature and
atmospheric pressure readings were taken and the flow rate of the HVS was
checked and adjusted at around 1.3 m3/min, and
complied with the range specified in the EM&A Manual (i.e. 0.6-1.7 m3/min).
-
The programmable digital
timer was set for a sampling period of 24 hrs, and the starting time, weather
condition and the filter number were recorded.
-
The initial elapsed time
was recorded.
-
At the end of sampling, on
site temperature and atmospheric pressure readings were taken and the final
flow rate of the HVS was checked and recorded.
-
The final elapsed time was
recorded.
-
The sampled filter was
removed carefully and folded in half length so that
only surfaces with collected particulate matter were in contact.
-
It was then placed in a clean
envelope and sealed.
-
All monitoring information
was recorded on a standard data sheet.
-
Filters were then sent
to Acumen Laboratory and Testing Limited for analysis.
·
Maintenance and
Calibration
-
The HVS and its
accessories were maintained in good working condition, such as replacing motor
brushes routinely and checking electrical wiring to ensure a continuous power
supply.
-
HVSs were calibrated using
TE-5025A Calibration Kit upon installation and thereafter at bi-monthly
intervals.
-
Calibration certificate of
the TE-5025A Calibration Kit and the HVSs are provided in Appendix I.
·

Note: (1) The noise monitoring stations proposed in the EM&A Manual (i.e.
Grand Waterfront Tower 3 with ID: E-N12 and Hang Chien Court Block J with ID:
E-N21) were not available for impact noise monitoring, therefore impact
monitoring was conducted at E-N12a and E-N21a as an alternative which was
agreed by the ER, IEC and EPD. (2) A correction of +3 dB(A) was made to the free-field measurements. |
|||
·
Monitoring Procedures
-
The sound level meter was set
on a tripod at a height of 1.2 m above the ground.
-
Façade measurement was
made at E-N12a.
-
Free field measurements was made at monitoring location E-N21a. A correction of +3
dB(A) shall be made to the free field measurements.
-
The battery
condition was checked to ensure the correct functioning of the meter.
-
Parameters such as
frequency weighting, the time weighting and the measurement time were set
as follows:
§ frequency weighting
§ time weighting: Fast
§ time measurement: Leq(30-minutes)
during non-restricted hours i.e. 0700 – 1900 on normal weekdays.
-
Prior to and after each
noise measurement, the meter was calibrated using the acoustic calibrator for
94 dB(A) at 1000 Hz. If the difference
in the calibration level before and after measurement was more than 1 dB(A),
the measurement would be considered invalid and repeat of noise measurement
would be required after re-calibration or repair of the equipment.
-
During the monitoring
period, the Leq, L10 and L90
were recorded. In addition, site
conditions and noise sources were recorded on a standard record sheet.
-
Noise measurement was
paused during periods of high intrusive noise (e.g. dog barking, helicopter
noise) if possible. Observations were recorded when intrusive noise was
unavoidable.
-
Noise monitoring was
cancelled in the presence of fog, rain, wind with a steady speed exceeding
5m/s, or wind with gusts exceeding 10m/s.
·
Maintenance and Calibration
-
The microphone head
of the sound level meter was cleaned with soft cloth at regular
intervals.
-
The meter and calibrator
were sent to the supplier or HOKLAS laboratory to check and calibrate at yearly
intervals.
-
Calibration certificates
of the sound level meters and acoustic calibrators are provided
in Appendix K.

W1 |
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

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

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
