ES.01 CRBC-Kaden Joint Venture (hereafter
¡§CRBC-Kaden JV¡¨) has been awarded by Highways Department as the Main Contractor
for the Contract HY/2013/12 - Northern Connection Toll Plaza and
Associated Works (hereinafter referred as ¡§the Contract¡¨) in July 2014. This is
a Designated Project to be implemented under Environmental Permit number EP-354/2009/D (hereinafter referred as ¡§the EP¡¨).
ES.02 Action-United
Environmental Services & Consulting (hereinafter referred as ¡§AUES¡¨) has
been commissioned as the Contract Environmental Team (hereinafter referred as
¡§the ET¡¨) to implement the relevant EM&A program in accordance with the
approved EM&A Manual and the Contract requirements, as well as the
associated duties.
ES.03 According
to the Approved EM&A Manual, baseline environmental monitoring is required to be conducted prior to
commencement of the construction works.
As such, baseline monitoring including air quality, ecology,
landscape and visual and cultural heritage was conducted. During the baseline monitoring period,
no construction activities under the Project or other external influencing
factors of significant concern were observed.
ES.04 Baseline
air quality monitoring was conducted by the ET of HyD
Contract HY/2012/08 between 17 and 31 October 2013. The monitoring results and established
Action and Limit Level for 1-hour TSP and 24-hour TSP would be adopted for this
Contract.
ES.05 Baseline
survey for Pitcher Plant has been conducted within the project area in
September 2013 by a suitably qualified ecologist. During the survey, 280 nos. of
individual were identified which were in good condition. Moreover, an initial survey for Pitcher
Plant by the Contract HY/2013/12 was conducted in mid-September 2014 to confirm
the number of existing Pitcher Plant.
A total of 280 nos. of individual Pitcher Plant located at Zone 1 to 7 was
identified. Since they are occurring on the rocky slope habitat
which will be impacted by the proposed slope works (Zone 1 to 7),
transplantation is required to minimize impacts to the population.
ES.06 Initial
tree survey and photographic record for existing Landscape was conducted on 22 September 2014 for TM-CLKL
prior commencement of the project.
ES.07 Condition
survey for the Grave G1 was conducted on 23 September 2014. The grave was generally in good
condition. However, a total of 10
cracks ranged from hairline to 2.8mm were identified in the cement rendering
and mortar of bricks of the grave.

Instrumentation
2.4.1.1
High volume Samplers
(HVS) completed with appropriate sampling inlets were
employed for air quality monitoring. Each sampler was composed of a motor, a
filter holder, a flow controller and a sampling inlet and its performance
specification complies with that required by USEPA Standard Title 40, Code of
Federation Regulations Chapter 1 (Part 50).
HVS
Installation
2.4.1.2
The
following guidelines were adopted during the installation of HVS:
Sufficient support was provided to secure the
samplers against gusty wind.
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 samples.
A minimum of 2 meters separation from any
supporting structure, measured horizontally was required.
No furnaces or incineration flues were
nearby.
Airflow around the sampler was unrestricted.
The samplers were more than 20 meters from
the drip line.
Any wire fence and gate, to protect the
sampler, should not cause any obstruction during monitoring.
Filter
Preparation
2.4.1.3
Fiberglass filters
were used [Note: these filters have a collection efficiency of larger than 99%
for particles of 0.3£gm diameter]. A HOKLAS accredited laboratory was
responsible for the preparation of 24-hr conditioned and preweighed
filter papers for monitoring team.
2.4.1.4
All prepared
filters were equilibrated in the conditioning environment for 24 hours before
weighing. The conditioning environment temperature was around 25 ¢XC and not
variable by more than ¡Ó3 ¢XC; the relative humidity (RH) was <50% and not
variable by more than ¡Ó5%. A convenient working RH was 40%.
Operating/
Analytical Procedures
2.4.1.5
Operating/analytical
procedures for the air quality monitoring were highlighted as follows:
Prior to the commencement of the 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. Then the
filter holding frame was 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 aluminum 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 laboratory for weighing. The elapsed time was also recorded.
Before weighing, all filters were
equilibrated in a conditioning environment for 24 hours. The conditioning
environment temperature should be between 25¢XC and 30¢XC and not vary by more
than ¡Ó3¢XC; the relative humidity (RH) should be < 50% and not vary by more
than ¡Ó5%. A convenient working RH is 40%. Weighing results were used for
further analysis of TSP concentrations collected by each filter.
Maintenance
and Calibration
2.4.1.6
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 condition.
All HVS were calibrated (five point
calibration) using Calibration Kit prior to the commencement of the baseline
monitoring and thereafter at bi-monthly intervals.
1-hour TSP
Measuring
Procedures
2.4.1.7
The
measuring procedures of the 1-hour dust meter are in accordance with the
Manufacturer¡¦s Instruction Manual as follows:
The 1-hour dust meter is placed at least 1.3
meters above ground.
Set POWER to ¡§ON¡¨ and make sure that the
battery level was not flash or in low level.
Allow the instrument to stand for about 3
minutes and then the cap of the air sampling inlet has been released.
Push the knob at MEASURE position.
Set time/mode setting to [BG] by pushing the
time setting switch. Then, start the background measurement by pushing the
start/stop switch once. It will take 6 sec. to complete the background
measurement.
Push the time setting switch to change the
time setting display to [MANUAL] at the bottom left of the liquid crystal
display. Finally, push the start/stop switch to stop the measuring after 1 hour
sampling.
Information such as sampling date, time, count value and site condition were recorded during the monitoring
period.
Maintenance
and Calibration
2.4.1.8
The following
maintenance/calibration is required for the 1-hour dust meter;
Check and calibrate the meter by HVS to check
the validity and accuracy of the results measured by direct reading method at
2-month intervals throughout all stages of the air quality monitoring.
2.5.1.1
The monitoring
results, name of laboratory and calibration details, and QA/QC results and
detection limits to be referred to the Baseline Monitoring Report under the
Contract HY/2012/08.
2.6.1.1
The baseline monitoring results formed the
basis for determining the air quality criteria for the impact monitoring. The
ET shall compare the impact monitoring results with air quality criteria set up
for 24-hour TSP and 1-hour TSP. Based

3.1.1.1
Ecological
baseline EM&A will consist of undertaking the following:
a walk-over survey, prior to
construction works, of the land and streams where works will be undertaken. It
may be necessary to rope off and protect specific habitats or species of
special interest identified during the ecological surveys
3.2.1.1
The
purpose of the walk over survey will be to confirm the existing ecological conditions,
with reference to the habitat maps included in the EIA Report and the established
baseline conditions, in relation to the extent and condition of the habitats
and species noted during the walkover survey. No detailed ecological surveys of flora
and fauna will be required at this stage.
3.2.1.2
Baseline
ecological walkover was conducted on 22 September 2014 and the results are
presented in below.
Observations
3.2.1.3
Two
major landscapes within the study area were tall shrubland
and plantation according to the habitat map in the approved EIA Report. To better record specific species of
native trees and shrubland, a general record about
their habit of growth was made.
Tall Shrubland
3.2.1.4
Shrubland habitat is densely populated with a mix native tree shrubby plant species
within study area. Native tree like Acacia confuse as well as other shrubby plant species are
planted broadly in this area. Shrublands are widely distributed.
The most common one are the Acacia confusa, Leucaena leucocephala, Macaranga tanarius and Clausena lansium. They have mixed with each other and get better greening benefit. No significant change to habitat maps in
the EIA Report was observed.
Plantation
3.2.1.5
Plantation
at the study area contain mainly roadside plantation for landscape use within
the study area. The plantation part, trees, for instance, Ficus microcarpa and Ficus elastica are most widely used as
roadside (riverside) plant and landscape greening. They are common evergreen
trees in Hong Kong and can grow as tall as fifteen meters which are considered
to be very aggressive. No significant change to habitat maps in the EIA Report
was observed.
Stream
3.2.1.6
The
outlet of the stream opposite to the
River Trade Terminal is now modified to an artificial culvert. Other than that,
the habitat types within the Study area are similar to the habitat maps in the EIA report.
3.2.1.7
The
developed area such as warehouses and River Trade Terminal was observed. No significant change to habitat maps in
the EIA Report was observed.
3.2.1.8
Part
of the Butterfly Beach as designated in EIA, is located at the eastern side of
the pillar point. No significant change
to habitat maps in the EIA Report was observed.
3.2.1.9
The
habitat map of Tuen Mun is shown in Appendix B.
3.3.1.1
During the Environmental Impact Assessment
(EIA) Stage of the TM-CLKL (which was approved on 23 October 2009), no Pitcher
Plant (Nepenthes mirabilis) was identified within the proposed works
area of the toll plaza. It was believed that the Pitcher Plant area identified
would not be directly impacted by the toll plaza works and the only mitigation measures
required were to install hoarding at the perimeter of the proposed works area
to avoid encroachment into the Pitcher Plant area. However, during an ecology
survey for the TMWB EIA in late 2011, Pitcher Plant was identified within the
proposed works area for the TM-CLKL toll plaza. Pitcher Plant is protected under the
Forestry Regulations (subsidiary legislation of the Forests and Countryside
Ordinance, Cap. 96) and the Protection of Endangered Species of Animals and
Plants Ordinance (Cap. 586). Discussion with Agriculture, Fisheries and
Conservation Department (AFCD) (27 October 2012) has confirmed that if the
TM-CLKL project was to impact the Pitcher Plant area that further mitigation
measures for the Pitcher Plant would be required under the TM-CLKL project. As
such, the project proponent Highways Department (HyD)
has appointed AECOM to undertake baseline survey and propose a transplantation strategy
for Pitcher Plant to be affected by the proposed TM-CLKL project.
3.3.1.2
A baseline Pitcher Plant survey was conducted
in September 2013 by a suitably qualified ecologist. The aim of the survey was to update,
identify and record the location, number, health condition (i.e. good, fair, or
poor), and suitability for transplantation of the affected individuals in order
to provide details for the transplantation exercise. Each identified individual
was tagged. The habitats present and representative plant species were
recorded.
3.3.1.3
The assessment area included the slope above
the toll plaza on which the Pitcher Plant populations have been previously
identified. The slope was surveyed
to identify the extent of the Pitcher Plant populations particularly those that
occur within and adjacent to the proposed works site.
Baseline Results on September 2013
3.3.1.4
The south-facing slope above the proposed
toll plaza supports a mosaic of shrubland, rocky
slope, plantation and watercourse habitats. Pitcher
Plant was recorded in the rocky slope, shrubland and
watercourse habitats. The rocky slope habitat comprised some exposed boulders
and bare ground; however, much of it has been naturally regenerated by shrubland species such as Dichotomy Forked Fern (Dicranopteris pedata), with
some encroachment by scattered Brisbane Box (Lophostemon confertus) saplings from the adjacent
plantation habitat. This habitat supported a Pitcher Plant population (see Zones 1-7 in Appendix C)
of
approximately 0.5 ha in size and 259 Pitcher Plants (see Appendix C,
Plates 1-3)).
3.3.1.5
In addition, three small areas (see Zones 8 ¡V 10 in Appendix C) of Pitcher Plant were recorded along
the watercourse in the shrubland habitat (see Appendix C,
Plate 4).
The watercourse comprised a narrow, shallow flow over bedrock with occasional
small, very shallow pooled areas. There is evidence that part of the flow is
being diverted for human use. Riparian vegetation comprised the shrubland habitat in which the watercourse flowed. Abundant
tree/shrub species found in the shrubland habitat
included Dwarf Mountain Pine (Baeckea frutescens), Pop-gun
Seed (Bridelia tomentosa), Eurya spp., Hong Kong Gordonia (Gordonia axillaris),
Pond Spice (Litsea glutinosa),
Pines (Pinus spp.), Wild Coffee (Psychotria asiatica), Rose Myrtle (Rhodomyrtus tomentosa),
Hedge Sageretia (Sageretia thea), and Brisbane Box (Lophostemon confertus).
While the understorey was dominated by Dichotomy
Forked Fern (Dicranopteris pedata), with
frequent Greenbrier (Smilax china),
and occasional Hainan Galangal (Alpinia hainanensis), Oriental Blechnum
(Blechnum orientale),
Bentham¡¦s Rosewood (Dalbergia benthami), Dianella (Dianella ensifolia), and Chinese Silvergrass
(Miscanthus sinensis).
3.3.1.6
The health and condition of the Pitcher Plant
individuals was assessed and each plant was assessed, tagged and photographed
by Pegasus Greenland Ltd.. All plants were assessed as
being in ¡§fair¡¨ health condition as summarized in Table 3. As the plants mostly grew on rock faces
with thin soils, the successful removal and transport of the existing
individuals is likely to be challenging given the weak nature of the plant¡¦s
roots.

Baseline Results on September 2014
3.3.1.7
Before commencement of the construction of
the Contract, the initial survey was conducted by Hong Kong Landscape in
September 2014 to confirm the location and number of the affected Pitcher Plants
by the proposed TM-CLKL project. During
the initial survey in September 2014, a total of 280 nos. of individual Pitcher
Plant located at Zone 1 to 7 was identified. They are occurring on the rocky slope
habitat which will be impacted by the proposed slope works (Zone 1 to 7). Each identified individual were tagged
and photographed. The location map
of the pitcher plants is shown in Appendix C.
3.3.1.8
280 nos. of Pitcher Plants identified in the
initial survey will require transplantation to minimize impacts to the
population. For those unaffected
Pitcher Plant in Zone 8 to 10, fencing or other physical barriers will be
erected for protection.
3.3.1.9
A transplantation proposal for Pitcher Plant in Zone 1 to 7 was submitted
to EPD and AFCD for agreement separately.
4.1.1.1
A
one off survey shall be conducted prior to commencement of any construction works.
A photographic record of the site
at the time of the contractor¡¦s possession of the site shall be prepared by the
Contractor and approved by the ER.

5.1.1.1
The
EIA has recommended that EM&A for cultural heritage resources is undertaken
during construction phase of the project. Implementation of the mitigation
measures recommended by the EIA will be monitored through the site audit
programme.
5.2.1.1
Prior
to construction, a baseline survey of the grave G1 should be undertaken to
establish the existing condition.
5.2.1.2
The
purpose of the baseline condition survey was to record the existing condition
of the grave and comprised the following task.
1.
Identification of grave near the Project Site;
2.
Carry out visual inspection for the condition
survey;
3.
Record the existing condition and evaluation
of structural integrity of the grave;
4.
Record the exact location of the grave prior
to construction commencement. This information formed the baseline information
for reference during construction phase;
5.
Submission of all records such as
photographs, grave locations, all detected cracks, defects and damage, if any.
5.3.1.1
The condition survey was conducted on 23
September 2014 and the finding area presented below.
5.3.1.2
The historical grave was identified during
the EIA stage of the project and the location of the grave (G1) was shown in Figure
5.1. It was observed that
plenty of bushes was grown around the grave. The general view of the grave was shown
in Figure
5.2.
|
5.4.1.1
The Grave G1 is generally in good
condition. However, a total of 10
cracks ranged from hairline to 2.8mm were identified in the cement rendering
and mortar of bricks of the grave. The
location of the cracks are shown in Figure
5.3. Detailed information
such as crack width and photographic record of the grave are summarized in Table

All
measures undertaken by the Contractor during the construction phase in the vicinity
of the grave shall be audited by the Environmental Team (ET), on a regular
basis to ensure compliance with the intended aims of the recommended mitigation
measures. Site inspections should be undertaken at least once per week throughout
the construction period adjacent to these properties. The main aim of the
survey is prevention of any possible damage to the grave and to ensure that the
proposed mitigation measures are implemented. The broad scope of the audit will
involve supervision of the following:
non-contact
effects of the engineering works, such as vibration from pneumatic drills which
could cause damage, such as foundation or wall cracks and loosening of tiles or
fixtures; and
contact between the historic structures and equipment and materials associated
with the engineering works.
5.5.1.2
Specifically,
the monitoring programme will entail the following tasks:
the extent of the agreed works areas should
be regularly checked during the construction phase to ensure the buffer with a
minimum of 1.0m set back of the permanent structure and a minimum of 0.7m
clearance from the grave, can be maintained during construction, and
ensure no stockpiling or equipment storage is affecting the structures.

Baseline survey for Pitcher Plant has been
conducted within the project area in September 2013 by a suitably qualified
ecologist. During the survey, a
total of 280 nos. of individual were identified in Zones 1 to 10 which were in
good condition. Moreover, an
initial survey for Pitcher Plant by the Contract HY/2013/12 was conducted in
mid-September 2014 to confirm the number of existing Pitcher Plant. A total of 280 nos. of individual
Pitcher Plant located at Zone 1 to 7 was identified. Since they are
occurring on the rocky slope habitat which will be impacted by the proposed
slope works (Zone 1 to 7), transplantation is required to minimize impacts to
the population.
6.1.1.4
Initial tree survey and photographic record
for existing Landscape was conducted on 22 September 2014 for TM-CLKL prior commencement of the
project.
6.1.1.5
Condition survey for the Grave G1 was
conducted on 23 September 2014. The
grave was generally in good condition.
However, a total of 10 cracks ranged from hairline to 2.8mm were
identified in the cement rendering and mortar of bricks of the grave.
