Monitoring Methodology and QA/QC results
Air
Quality
3.3.1.
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.
3.3.2.
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.
3.3.3.
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.
3.3.4.
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.
3.3.5.
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 and ALS Technichem (HK) Pty Ltd) for
analysis.
3.3.6.
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.
3.3.7.
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

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 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.

Accidental Spillage
In order to prevent accidental spillage of chemicals, the
following is recommended:
· 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.

Construction and Demolition Material
· Maintain temporary stockpiles and reuse excavated fill material
for backfilling and reinstatement;
· Carry out on-site sorting;
· Make provisions in the Contract documents to allow and promote
the 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 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 licence.
· 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.

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.

Excavation of the Contaminated Soil
· 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.
