Air Quality Monitoring Results
Monitoring Parameters
3.1.
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.
3.2.
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.
3.3.
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.
Monitoring Equipment
3.4.
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).
3.5.
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 certificate of dust monitoring equipment is attached in Appendix
H.
3.6.
A summary of the equipment that was deployed for
the 24- hour averaged monitoring is shown in Table 3.1. The TSP
monitoring was conducted as per the schedule presented in Appendix G.

Monitoring Methodology and QA/QC results
3.8.
The 1-hour TSP monitor, portable dust meters (Sibata
Digital Dust Indicator Model LD-5R) was 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.
3.9.
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 I;
u The airflow over
time during sampling process was recorded by the HVS.
3.10.
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 Any wire fence and
gate, to protect the sampler, should not cause any obstruction during
monitoring
u A secured supply
of electricity is needed to operate the samplers.
3.11.
Preparation of Filter Papers:
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.
3.12.
Field Monitoring:
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 1.13-1.19 m3min-1, which
was within the range specified in the EM&A Manual (i.e. 0.6- 1.7 m3min-1);
u The programmable
timer was set for a sampling period of 24 hours ±hour, 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) for analysis.
3.13.
Maintenance and Calibration:
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 Calibration Kit and TE-5028A Calibration KIT. HVS is
calibrated in fortnightly Intervals. The calibration records for the HVS is
given in Appendix H.
3.14.
Wind Data Monitoring:
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 if malfunction
occurred or data was not recorded from HKO.
Monitoring Locations
3.15. During the site visit, air quality monitoring station Hong Kong
International Trade and Exhibition Centre had been recommended in the approved
EM&A Manual. A designated air quality monitoring location was identified
and agreed with IEC and EPD. Detail of the air monitoring station is described
in Table 3.2. The location plan of air quality monitoring stations is

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 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 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 September) 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
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 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.

· All the tanks, containers,
storage area should be bunded and the locations should be locked as far as
possible from the sensitive watercourse and stormwater drains;
· The Contractor should register
as a chemical waste producer if chemical wastes would be generated. Storage
of chemical waste arising from the construction activities should be stored
with suitable labels and warnings.
Disposal of chemical wastes
should be conducted in compliance with the requirements as stated in the
Waste Disposal (Chemical Waste) (General) Regulation.

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.

· 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 the course of construction.

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.

Land-based Sediment
· All construction plant and
equipment shall be designed and maintained
to minimize the risk of silt, sediments, contaminants or other pollutants 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.

Chemical Waste
· Chemical waste that is
produced, as defined by Schedule 1 of the Waste Disposal (Chemical Waste)
(General) Regulation, should be handled in accordance with the Code of
Practice on the Packaging, Labelling and Storage 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

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.
· Aluminum 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.

· Prior to commencement of the
excavation works at the contamination zone, the zone should be clearly marked
out on site and the surface levels recorded. Excavation of contaminated
material should be undertaken using dedicated earth-moving plant.
· The excavated contaminated
soils would be stockpiled at designated area on site and covered by sheet to
prevent dispersion of contamination during stockpiling.
· The Contractor should pay
attention to the selection of suitable groundwater lowering schemes and
discharge points if the groundwater table is higher than the contaminated
soils during excavation. The Contractor should also obtain a valid Water
Pollution Control Ordinance (WPCO) discharge licence from EPD where
applicable.
