Filters Preparation
2.5.5
Wellab
Limited (HOKLAS Registration No. HOKLAS083) is a HOKLAS accredited laboratory
and responsible for the preparation of 24-hour conditioned and pre-weighed
filter papers for the monitoring team.
2.5.6
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%.
Operating/Analytical
Procedures
2.5.7
Operating/analytical
procedures for the air quality monitoring were highlighted as follows:
·
Prior to the commencement
of dust sampling, the flow rate of the HVS was properly set (between 1.1 m3
/min. and 1.4 m3 /min.) in accordance with the manufacturer's
instruction to within the range recommended in USEPA Standard Title 40, CFR
Part 50;
·
The power supply was
checked to ensure the sampler worked properly;
·
On sampling, the sampler
was operated for 5 minutes to establish thermal equilibrium before placing any
filter media at the designated air quality monitoring station;
·
The filter holding frame
was then removed by loosening the four nuts and carefully a weighted and
conditioned filter was centered with the stamped number upwards, on a
supporting screen;
·
The filter was aligned on
the screen so that the gasket formed an airtight seal on the outer edges of the
filter. The filter holding frame was then tightened to the filter holder with
swing bolts. The applied pressure should be sufficient to avoid air leakage at
the edges;
·
The shelter lid was closed
and secured with the aluminium strip;
·
The timer was then
programmed. Information was recorded on the record sheet, which included the
starting time, the weather condition and the filter number (the initial weight
of the filter paper can be found out by using the filter number);
·
After sampling, the filter
was removed and kept in a clean and tightly sealed plastic bag. The filter
paper was then returned to the HOKLAS accredited laboratory (Wellab Ltd.) for
reconditioning in the humidity-controlled chamber followed by accurate weighting
by an electronic balance with a readout down to 0.1mg. The elapsed time was
also recorded; and
·
Before weighing, all
filters were equilibrated in a conditioning environment for 24 hours. The
conditioning environment temperature should be between 25°C and 30°C and did
not vary by more than ±3°C; the RH should be < 50% and did not vary by more
than ±5%. A convenient working RH is 40%. Weighing results were returned for
further analysis of TSP concentrations collected by each filter
Maintenance/Calibration
2.5.8
The
following maintenance/calibration was required for the HVS:
·
The high-volume motors and
their accessories were properly maintained. Appropriate maintenance such as
routine motor brushes replacement and electrical wiring checking were made to
ensure that the equipment and necessary power supply are in good working
conditions; and
·
All HVS were calibrated
(five point calibration) using Calibration Kit prior to the commencement of
baseline monitoring and thereafter at bi-monthly intervals.
Instrumentation
(Sibata Model: LD-5R)
2.5.9
The
measuring procedures of the dust meters were in accordance with the
Manufacturer’s Instruction Manual as follows:
·
Placed the dust meters at
least 1.3m above ground
·
Set POWER to “ON” and make
sure that the battery level not flashed or in low level;
·
Pulled the air sampling
inlet cover up;
·
Pushed the knob at MEASURE
position;
·
Set time/mode setting to
[BG] by pushing the time setting switch. Then, started the background
measurement by pushing the start/stop switch once. It took 6 sec. to complete
the background measurement;
·
Turned knob to SENSI. ADJ
position and pressed in;
·
Pushed Start/Stop switch
once;
·
Gently returned knob to
the MEASURE position;
·
Pushed the time setting
switch to change the time setting display to [LOG] at the bottom left of the
liquid crystal display;
·
Removed the cap and
started measurement; and
·
Information such as
sampling date, time, count value and site condition were recorded during the
monitoring period.
Maintenance/Calibration
2.5.10 The following
maintenance/calibration was required for the direct reading dust meter:
·
Direct reading dust meter
shall be used in determining 1-hour TSP and 24-hour TSP at air quality
monitoring points. The direct reading dust meters have been calibrated against
high volume samplers (HVSs) bi-monthly. A 2-day, three 3-hour measurement results per day from
direct reading dust meters were taken to compare with the sampling results from
the HVSs. The correlation between the direct reading dust meters and the HVSs
were then concluded. By accounting for the correlation factor, the direct
reading dust meters are considered to achieve comparable results as that of the
HVSs.
·
The HVS used to calibrate
the direct dust monitor will need to be calibrated bi-monthly. Details of maintenance
and calibration for the HVS refers to Section 2.5.8. Calibration for the

3.4.1
As
referred to the technical memorandum issued under the Noise Control Ordinance
(NCO), sound level meters in compliance with the International Electrotechnical
Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1)
specifications were used for carrying out the construction noise monitoring.
3.4.2
Noise
measurements were not made in fog, rain, wind with a steady speed exceeding 5
m/s or wind with gusts exceeding 10 m/s. The wind speed was checked with a
portable wind speed meter capable of measuring the wind speed in m/s.
3.4.3
Sufficient
numbers of noise measuring equipment and associated instrumentation were
prepared by the ET. All the equipment and associated instrumentation were
clearly labelled.
3.4.4
The
monitoring procedures are as follows:
·
For façade measurement,
the monitoring station was set at a point 1 m from the exterior of the
sensitive receivers building façade and set at a position 1.2 m above the
ground. For free-field measurement, the monitoring station was set at a
position 1.2 m above the ground.
·
The battery condition was
checked to ensure good functioning of the meter.
·
Parameters such as
frequency weighting, the time weighting and the interval were set as follows:
-
Frequency weighting: A
-
Time weighting: Fast
-
Interval: 30 minutes (Leq(30mins))
·
Prior to and after each
noise measurement, the meter was calibrated using an acoustic calibrator for
94.0 dB at 1000 Hz. If the difference in the calibration level before and
after measurement is more than 1.0 dB, the measurement was considered invalid and
repeat of noise measurement will be required after re-calibration or repair the
equipment.
·
At the end of the
monitoring period, the values of Leq, L10 and L90
were recorded. In addition, noise sources were recorded on a standard record
sheet.

Ecology
6.1.1
This
section was derived from the ecological monitoring conducted during the
construction phase by the Remaining Phase ET, supplemented with findings
retrieved from the First Phase ET under Service Contract No. NDO 04/2019
Environmental Team for Environmental Monitoring and Audit Works in Construction
Phase for the First Phase Development of Kwu Tung North and Fanling North New
Development Areas. This approach was undertaken to prevent redundancy in survey
efforts.
Weekly Site
Inspection
6.2.1
Weekly
site inspections by the ET from the First Phase of the KTN/FLN NDAs Project for
ecological mitigation measures are conducted as part of the overall weekly
environmental site inspections. These inspections audit the ecological
mitigation measures implemented within the active works area to ensure that the
activities do not significantly impact the ecologically sensitive receivers in
the active works areas.
Monitoring of
Measures to Minimise Disturbance to Water Birds in Ng Tung River, Sheung Yue
River, Shek Sheung River and Long Valley
6.2.2
As
stipulated in Section 12.3.2.5 of the Updated EM&A Manual, if development
under the NDAs project occurs within 200m of Sheung Yue River, Ng Tung River,
Shek Sheung River and Long Valley, weekly transect monitoring at high and low
tides (above/below 1.5m at Tsim Bei Tsui Station) should be conducted. The
monitoring aims to identify and count bird species in the river channels and
Long Valley Nature Park (LVNP) and detect any disturbances from construction
activities, following the methodology in Table 12.1 of the Updated EM&A
Manual. Monitoring in Long Valley should follow the Hong Kong Bird Watching
Society (HKBWS) bird monitoring programme's methodology for comparable and
comprehensive results.
Monitoring of
Measures to Minimise Impacts to Ma Tso Lung Stream and Siu Hang San Tsuen
Stream, and Long Valley
6.2.3
As
stipulated in Section 12.3.2.14 of the Updated EM&A Manual, aquatic fauna
monitoring should be conducted monthly during the wet season (April – October) of
the construction phase.
Monitoring of
Measures to Minimise Impacts on Ecological Sensitive Habitats from Disturbance
and Pollution
6.2.4
As
stipulated in Section 12.3.2.17 of the Updated EM&A Manual, measures to
minimize impacts should be monitored during the construction phase. The purpose
of these surveys is to assess the effectiveness of measures aimed at reducing
disturbances and pollution in ecologically sensitive habitats through standard
fauna transect surveys.

Monitoring of
Measures to Minimise Disturbance to Water Birds in Ng Tung River, Sheung Yue
River, Shek Sheung River and Long Valley
Monitoring Methodology
6.3.1
Birds
identified by their calls but not visually located were recorded as
"heard", while those observed flying over the survey area were noted
as "in flight." Species of conservation importance were also
specified. Additional information at the time of the survey, such as weather
conditions, tidal conditions, tide levels, and noticeable natural or
anthropogenic activities, were documented. For the avifauna survey,
ornithological nomenclature referenced The Avifauna of Hong Kong (Carey
et al., 2001), The Birds of Hong Kong and South China (Viney et al.,
2005), and the most recent updated lists from other sources (e.g., Hong Kong
Bird Watching Society).
Monitoring
Parameters
6.3.2
The
monitoring parameters are as follows:
·
Abundance of birds;
·
Types of habitats utilized
by birds; and
·
Notable bird behaviours
such as roosting, feeding, nesting and presence of juveniles.
Monitoring Location
6.3.3
For
this reporting month, First Phase ET conducted avifauna monitoring at Ng Tung
River, Sheung Yue River, and Long Valley, while the Remaining Phase ET
conducted avifauna monitoring at Shek Sheung River. Relevant transect routes
are summarized in Table 6.2 and illustrated in Figure 6.1 and Figure 6.2. As the sensitive receivers are large waterbirds and are
easily visible, the transect routes only needed to follow one riverbank.

Monitoring of
Measures to Minimise Impacts to Ma Tso Lung Stream and Siu Hang San Tsuen
Stream, and Long Valley
6.3.15 Monitoring of larger
organisms such as fish species will be carried out through direct counting,
while sampling aquatic invertebrates will involve kick-netting and
sweep-netting. Three replicates will be conducted for invertebrate sampling at
each sampling point. During kick-netting, the net will be positioned at a
location with the opening facing the water current while disturbing the
substrate through kicking to dislodge organisms from the stream bed.
Sweep-netting will be applied to water bodies without water current according
to on-site conditions. Species observed will be identified to the lowest
possible taxonomic level with their relative abundance recorded, with the use
of dissecting microscope especially for small organisms not identifiable through
the naked eye.
Monitoring Parameters
6.3.16 The monitoring
parameters are as follows:
·
Species composition and abundance;
·
Distribution of invertebrates and fish fauna;
and
·
Specify species of conservation importance, if
any.

Monitoring of Measures to Minimise Impacts on Ecological Sensitive Habitats
from Disturbance and Pollution
Monitoring Methodology
Terrestrial Mammal
6.3.25
Mammal
surveys were conducted both during the day and at night along transect routes
that may be potentially utilized by terrestrial mammals. Observations included
field signs such as droppings, footprints, diggings, and burrows left by larger
terrestrial mammals. Any mammals directly observed were recorded, and
identification was as accurate as possible based on the field signs.
6.3.26
Bat
surveys were conducted along the transect routes shortly after sunset using a
bat detector to record echolocation calls. The relative abundance of the
species encountered were estimated with reference to the baseline monitoring
results, using a scale from one (species recorded within transect routes) to
three (dominant species within transect routes), for comparison between
baseline and current monitoring results. Mammal nomenclature followed Shek
(2006).
6.3.27
Echolocation
calls of bats were recorded using a bat detector, which listed possible bat
species with similar call patterns and frequencies. The structure of the
recorded echolocation calls was later analysed to identify species as
accurately as possible. Due to the lack of literature on echolocation call
structures, field identification of some bat species in Hong Kong is
challenging, and some species could only be identified to the genus level or
remain unidentified from the recordings.
6.3.28 Identification of bat
species encountered in the surveys was made by considering the possible species
suggested by the bat detector, their distribution in Hong Kong, previous
records in the EIA Report and Baseline Monitoring Report, and the structure of the
echolocation calls (including call structure, frequency, duration, and
inter-pulse interval) with reference to relevant literature.
Herpetofauna (Amphibians and Reptiles)
6.3.29
Both
daytime and nighttime amphibian surveys were conducted whenever possible
following or during periods of rainfall, focusing on areas suitable for
amphibians (e.g., forests, shrublands, grasslands, streams, ponds, marshes,
etc.). Calling amphibians were recorded, supplemented by visual observations of
eggs, tadpoles, adult frogs, and toads.
6.3.30 Active searches of
appropriate microhabitats, such as stones, pond bunds, crevices, and leaf
debris, was primarily conducted. Observations of exposed, basking, and foraging
reptiles were also carried out. Nomenclature for amphibians and reptiles
followed Chan et al. (2005) and Karsen et al. (1998), respectively.
Butterfly and Odonates
6.3.31 Butterflies and
dragonflies observed along the transects were identified and counted. Special
attention was given to their preferred habitats, such as watercourses,
fishponds, and vegetated areas. Nomenclature and protection status of the
species followed Lo et al. (2005) for butterflies and Tam et al. (2011) for
dragonflies.
Monitoring Parameters
6.3.32 The monitoring
parameters are as follows:
·
Species composition;
·
Abundance;

Details of the Influencing
Factors
6.3.42
The
details of the influencing factors were adopted from the observations of the
First Phase ET. During the monitoring of measures to minimize disturbance to
waterbirds in Long Valley and Sheung Yue River, anthropogenic activities such
as excavation and other construction activities were observed near Long Valley.
It should also be noted that the Long Valley Nature Park has been opened to
the public since 09 November 2024. Potential increase in people visiting the
park may potentially impact the habitats in Long Valley and cause disturbances
to the bird communities in this area. Construction works were also observed along
Sheung Yue Riverr.
6.3.43
During
the monitoring of measures to minimize disturbance to waterbirds in Ng Tung
River, various anthropogenic activities were observed, such as construction
works along Transect T2, recreational use of remote-control boats and toy helicopters
in both Transects T1 and T2, and recreational fishing along these two transects.
Survey Summary
6.3.44

Landscape and Visual
7.1.1
According
to the approved EM&A manual and Updated EM&A Manual for the First Phase,
site audits should be undertaken at least once every two weeks during the construction
period, by the Environmental Team. Particularly, to check that the proposed
landscape and visual mitigation measures are properly implemented and
maintained as per their intended objectives. Mitigation measures recommended in
the EIA Report as the audit requirements including, preservation of existing
vegetation, transplanting of affected trees, compensatory tree planting,
control of night-time lighting glare, erection of decorative screen hoarding
and management of construction activities and facilities.
7.2.1
Bi-weekly
landscape and visual site audits were carried out by the ET during the
reporting period. Inspections were carried out on 2, 16 and 28 April 2026 for
ND/2024/01, 2, 17 and 28 April 2026 for ND/2024/02, 15 and 27 April 2026 for
ND/2024/03, 10 and 24 April 2026 for ND/2024/04, 9 and 21 April 2026 for
ND/2024/06, 9 and 23 April 2026 for ND/2024/07. No particular observation was
recorded in this reporting period.
7.3.1
Should
any non-compliance of the criteria occur, action in accordance with the Event
and Action Plan in Appendix 7.1 shall be followed.
8.1.1
According
to the approved EM&A Manual and Updated EM&A Manual for the First Phase,
an ambient arsenic monitoring is required to be conducted in KTN during the
clean-up processes of arsenic containing soil and the construction phase.
8.1.2
The RSP
concentration was measured by HVS equipped with PM10 selector (PM10 HVS)
following the "Reference Method for the Determination of Particulate
Matter as PM10 in the Atmosphere" Part 50 Chapter 1 Appendix J, Title 40
of the Code of Federal Regulations of the USEPA.
8.1.3
The
Dust-laden air was drawn through PM10 HVS fitted with a conditioned
pre-weighting filter paper, at a controlled rate. After sampling for 24-hour,
the filter paper with retained PM10 particulates was collected and returned to
the laboratory for drying in a desiccator followed by accurate weighting.
24-hour average RSP levels were calculated from the ratio of the mass of PM10
particulates retained on the filter paper to the total volume of air sampled.
8.1.4
The
weighted filter paper was prepared for arsenic testing through a "Hot Acid
Extraction Procedure". The extracted material was tested for arsenic by
using Inductively Coupled Plasma/Mass Spectrometry (ICP/MS). The extraction and
testing were referenced to the following methods:

Instrumentation
8.5.1
HVS
(GMW PM10 (TE6070X)) complete with appropriate sampling inlets was employed for
24-hour RSP monitoring. The sampler was composed of a motor, a filter holder, a
flow controller and a sampling inlet and its performance specification complied
with that required by USEPA Standard Title 40, Code of Federation Regulations
Chapter 1 (Part 50).
8.5.2
The
following guidelines were adopted during the installation of HVS:
·
a horizontal platform with
appropriate support to secure the samplers against gusty wind was provided;
·
no two samplers were
placed less than 2 meters apart;
·
the distance between the
sampler and an obstacle, such as buildings, was at least twice the height that
the obstacle protrudes above the sampler;
·
a minimum of 2 meters of
separation from walls, parapets and penthouses was required for rooftop
samplers;
·
a minimum of 2 meters
separation from any supporting structure, measured horizontally was required;
·
no furnace or incinerator
flue was nearby;
·
airflow around the sampler
was unrestricted;
·
the sampler was more than
20 meters from the dripline;
·
any wire fence and gate,
to protect the sampler, were not cause any obstruction during monitoring;
·
permission was obtained to
set up the samplers and to obtain access to the monitoring stations; and
·
a secured supply of
electricity was needed to operate the samplers
Operating/analytical
procedures for the operation of HVS
·
Prior to the commencement of the dust sampling,
the flow rate of the high volume sampler was properly set (between 1.1 m3
/min. and 1.4 m3 /min.) in accordance with the manufacturer's
instruction to within the range recommended in USEPA Standard Title 40, CFR
Part 50;
·
The power supply was checked to ensure the
sampler worked properly. On sampling, the sampler was operated for 5 minutes to
establish thermal equilibrium before placing any filter media at the designated
air monitoring station;
·
The filter holding frame was then removed by
loosening the four nuts and a weighted and conditioned filter was carefully
centered with the stamped number upwards, on a supporting screen;
·
The filter was aligned on
the screen so that the gasket formed an airtight seal on the outer edges of the
filter. The filter holding frame was then tightened to the filter holder with
swing bolts. The applied pressure was sufficient to avoid air leakage at the
edges;
·
The shelter lid was closed
and secured with the aluminium strip;
·
The timer was then
programmed. Information was recorded on the record sheet, which included the
starting time, the weather condition and the filter number (the initial weight
of the filter paper can be found out by using the filter number);
·
After sampling, the filter
was removed and sent to the Wellab Ltd. for weighing. The elapsed time was also
recorded; and
·
Before weighing, all
filters were equilibrated in a conditioning environment for 24 hours. The
conditioning environment temperature was between 25°C and 30°C and did not vary
by more than ±3°C; the relative humidity (RH) was < 50% and did not vary by more
than ±5%. A convenient working RH was 40%. Weighing results were further
analysis of RSP concentrations collected by each filter.
8.6.1
The
following maintenance/calibration was required for the HVS:
·
The high volume motors and
their accessories were properly maintained. Appropriate maintenance such as
routine motor brushes replacement and electrical wiring checking were made to
ensure that the equipment and necessary power supply were in good working
condition; and
·
High volume samplers were
calibrated at bi-monthly intervals using TE-5025A Calibration Kit throughout
all stages of the ambient arsenic monitoring.
8.7.1
Quartz
filters of size 8” x 10” were labelled before sampling. A HOKLAS accredited
laboratory, Wellab Ltd., was responsible for the preparation of 24-hour
conditioned and pre-weighed filter papers for the monitoring team. The balance
for weighting filter paper was regularly calibrated against a traceable
standard.
8.7.2
All
filters, which were prepared and 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%.
8.7.3
Wellab

1. The construction work has not commenced in the
reporting month.
13.1.2 Potential environmental
impacts arising from the above construction activities are mainly associated
with construction noise impact, water quality impact, ecological impact, waste
management, and landscape and visual.
Dust
•
Regular watering to reduce dust emissions from
exposed site surface;
•
Stockpile of dusty materials shall be covered
entirely by impervious sheeting;
•
Provide vehicles washing facilities at all site
exits to wash away any dusty materials from vehicle body;
•
NRMM Labels should be displayed on the
applicable equipment on site by the Contractor;
•
Provision of water sprinklers along the haul
road for dust suppression.
Noise
•
Only well-maintained plant should be operated
on-site, and plant should be maintained regularly during the construction
programme; and
•
Quality Powered Mechanical Equipment (QPME)
should be adopted as far as possible.
Water Quality
•
No effluent discharge would be allowed before
acquired the effluent discharge license;
•
Surface run-off from construction sites should
be discharged into dedicated discharge point via adequately designed sand/ silt
removal facilities;
•
Channels/ earth bunds/ sandbags barriers should
be provided on site to properly direct stormwater to silt removal facilities;
•
Silt removal facilities, channels and manholes
should be maintained, and the deposited silt and grit should be removed
regularly;
•
Open stockpiles of construction materials on
sites should be covered with tarpaulin or similar fabric during rainstorms; and
•
Perimeter channels should be provided on site
boundaries where necessary to intercept stormwater run-off from outside the
site so that it will not wash across the site.
Waste Management
•
Provision of sufficient waste disposal points
and regular collection of waste;
•
Regular cleaning and maintenance programme for
drainage system; and
•
Chemical containers shall be stored with drip
tray underneath.
Landscape and Visual
•
Construction activities shall be carefully
designed to minimize impact on existing retained trees.
Land Contamination
•
Stockpiling site(s) should be lined with
impermeable sheeting and bunded. Stockpiles should be properly covered by
impermeable sheeting to reduce dust emission during dry season or contaminated
run-off during rainy season. Watering should be avoided on stockpiles of soil
to minimise runoff.
Landfill Gas Hazard
•
“No Smoking” and “No Naked Flame” notices in
Chinese and English should be posted prominently around the construction site.
Ecology
•
Properly erect and maintain 2m high solid
barriers for protection.
•
An individual of orchid Eulophia cernua was found growing
underneath the pipeline adjacent to the access road leading to the summit of
the Table Hill Freshwater Service Reservoir for Contract No. ND/2024/06. The
species of conservation importance should be fenced off for protection to minimise
the potential impacts aroused from nearby construction activities as far as
possible.
