2.5 Summary of EM&A Requirements
The EM&A programme as specified in the
EM&A Manual has been implemented during the construction stage.
In the reporting period, impact monitoring
of LAeq, 30min noise levels was carried out at the monitoring locations as
shown in Table 1 once a week. Also, 24-hour TSP monitoring was conducted at the
monitoring locations as shown in Table 1 once a week. Impact water quality monitoring
at Telegraph Bay was also undertaken at the monitoring locations as shown in
Table 2 three working days per week at mid-ebb and mid-flood tides.
Action and Limit Levels for construction
noise and air quality as well as water quality are shown in Appendices B1 and B2 respectively. Should non-compliance of
the criteria occurs, action in accordance with the respective Event and Action
Plans for construction noise, air quality and water quality in the EM&A
Manual / Updated EM&A Manual / Silt Curtain Plan should be carried out.
Monthly monitoring of the ardeid night
roost location beside Wong Chuk Hang Nullah by qualified ecologist was also
conducted.
In addition, regular site inspection to
active works areas was carried out. The areas of inspection included the
pollution control and mitigation measures within the site. Waste management and
landscape and visual aspects were covered.
24-hour TSP samples were collected by High
Volume Sampler (Graseby-Andersen) following United Sates Environmental
Protection Agency regulations.
The sampling procedure follows to that
described in the App. B of Pt 50 in 40CFR Ch.1 (U.S. Environmental Protection
Agency). TSP is sampled by drawing air through a conditioned, pre‑weighed
filter paper inside the high volume sampler at a controlled rate. After 24‑hour
sampling, the filter paper with retained particles is collected and returned to
the laboratory for drying in a desiccators followed by weighing. TSP levels are
calculated from the ratio of the mass of particulate retained on the filter
paper to the total volume of air sampled.
The samplers have been properly
maintained. Prior to dust monitoring commencing, appropriate checks have been
made to ensure that all equipment and necessary power supply are in good
working condition.
The flow rate of the high volume sampler
with mass flow controller is calibrated using an orifice calibrator. Initial
calibration (five points) is conducted upon installation and prior to
commissioning. Calibration will be carried out every six months. The calibration
records are shown in Appendix C.
To examine the construction dust levels,
24-hour TSP monitoring was undertaken at the monitoring locations as shown in
Table 1 according to the EM&A Manual.
Monitoring results are presented
in the following table (see Appendix D for graphical plots).
The 24-hour TSP levels were within the Action Level. No exceedance was found.
This indicates that the construction activities did not have a noticeable
adverse effect on the general air quality of the project areas. However, excavation and reinstatement works
by other Project were observed in the vicinity of monitoring station DTB1 at
Telegraph Bay barging point during the reporting month, which have generated
fugitive dust emitting to the local environment. The dust suppression measures,
such as water spraying on the haul road and tipping hall, for the barging point
operation were ongoing.

Monitoring was conducted using B&K
sound analysis equipment – B&K SLM 2250. Microphone was extended 1 meter from
building facades and oriented towards the works area.
B&K 2250 sound level meters and
B&K 4231 calibrators which complied with the International Electrotechnical
Commission Publication 651:1979 (Type 1) and 804:1985 (Type 1), specification
as referred to in the Technical Memoranda to the NCO were used for the impact
monitoring. The sound level meters and calibrators are verified by the
certified laboratory or manufacturer once every two years to ensure they
perform to the same level of accuracy as stated in the manufacturer’s
specifications. The calibration records are shown in Appendix C.
Immediately prior to and following each
set of measurements at any NSR, the accuracy of the sound level meter was
checked using an acoustic calibrator generating a known sound pressure level at
a known frequency. If the
calibration levels before and after the measurement differs by more than 1.0dB,
the measurement shall be repeated to obtain a reliable result (note: maximum
deviation during this initial baseline monitoring period was 0.3dB). Periods of
prolonged or repeated overloading of the sound level meter detector were
avoided by setting the meter with adequate headroom prior to commencing
measurements. Measurements were
recorded to the nearest 0.1 dB, with values of 0.05 being rounded up.
Impact monitoring of LAeq, 30min noise
levels was undertaken to measure construction noise levels in accordance with
the Updated EM&A Manual at the monitoring locations as shown in Table 1. The
monitoring was conducted during the course of construction works, please refer
to S2.2 for major construction activities of the respective SIL(E) civil works contracts
in the
reporting month. Weather conditions throughout the monitoring period were mild
with light wind of not exceeding 2-3m/s on average.
Noise monitoring results are presented in the following

Construction Noise Mitigation Measures Plan
In accordance with the Silt Curtain Plan
for Marine-based Decommissioning of Temporary Pier at Telegraph Bay submitted
under EP condition 2.16(a), water quality monitoring will be carried out during
the marine-based demolition works at the Telegraph Bay barging point. The
baseline water quality monitoring at Telegraph Bay was scheduled and completed in
August 2014. The Water Quality Baseline Monitoring Report for Marine-based
Demolition work of the temporary pier at Telegraph Bay was submitted to EPD on 26
November 2014 and deposited at the EIAO Register OFfice on 4 December 2014.
Monitoring Methodology
Water quality was
monitored in terms of the following parameters: Dissolved Oxygen (DO, mg/L) and
Dissolved Oxygen Saturation (DO %), temperature (oC), pH, turbidity
(NTU), salinity (ppt), suspended solids (mg/L) and water depth (m) in
accordance with the EM&A Manual of the HKWDT project. All parameters were
measured in-situ whereas SS shall be determined by the laboratory.
Water samples were
taken with a water sampler, consisting of a transparent PVC cylinder of 2
litres that can be effectively sealed with cups at both ends. The water sampler
has a positive latch system to keep it open and prevent premature closure until
released by a messenger when the sampler arrives is at the pre-determined
depth.
Measurement was
taken at 3 water depths, namely, 1m below water surface, mid-depth and 1m above
sea bed, except where the water depth less that 6m, the mid-depth station may
be omitted. Should the water depth be less than 3m, only the mid-depth station
was monitored.
Duplicate in-situ
measurements and samples were collected and analyzed to ensure a robust
statistically interpretable dataset. Where the difference in value between the
first and second measurement of DO or turbidity parameters is more than 25% of
the value of the first reading, the reading was discarded and further readings
were taken.
Water samples were
stored in high-density polythene bottles, packed in ice and delivered to the
laboratory of ALS Technichem (HK) Ltd., a HOKLAS accredited laboratory. The SS
analyses followed the standard method APHA 2540D with a detection limit of
1mg/L.
A digital depth
detector was employed to determine the water depth at selected stations when
flows permit.
Calibration Requirements
On-site monitoring
equipment namely the salinity meter, pH meter, turbidity meter, dissolved
oxygen meter and temperature meter were calibrated before use. The
methodologies for the calibration are referred to the instruction manual
provided by the manufactures respectively.
The calibration records are shown in Appendix
C. Response of
sensors and electrodes was checked with certified standard solutions before
each use.
Monitoring Results
Impact water
quality monitoring was undertaken in accordance with the Silt Curtain Plan at
the respective designated monitoring locations at Telegraph Bay as shown in
Table 2 during the reporting period. Monitoring results and graphical plots are
presented in Appendix D.
3.4 Action taken in Event of Exceedance
There was no exceedance in air quality, noise and water
quality monitoring parameters recorded in the reporting period, therefore no
action was taken.
The landscape and visual mitigation
measures undertaken by the contractors during the construction phase have been
audited on a regular basis according to the EM&A Manual.
Regular inspections and audits were conducted
by the Certified Arborist as required by the EP and it was found that the
transplanting works and the tree protection works being carried out by the
civil works and transplantation contractors were in accordance with the EP/ EIA.
Necessary tree removal or protection works were being carried out in accordance
with the EP/ EIA or approved Tree Removal Application. No non-compliance was identified in the
reporting period.
No immediate hazards were noted for any of
the OVTs during reporting period.
Health conditions of the two retained and
pruned trees, Ficus elastica, located
at Wong Chuk Hang San Wai have been monitored. The contractor had enhanced the
tree protection zone and was reminded to properly maintain the protection zone.
Total of 464 trees of the SIL(E) had been
transplanted as of the reporting month. They were mostly transplanted to the
holding nursery at Chung Hom Shan and Kellett Bay, permanent receptor sites
such as Lok Ma Chau, Telegraph Bay or in-situ under project areas.
Auditing of the ecological mitigation
measures during the construction phase have been carried out on a regular basis
according
to the EM&A Manual.
Regular inspections to the works areas
around the ardeid night roost have been conducted by the ecologist to check the
ecological mitigation measures with regard to the ardeids at Wong Chuk Hang
Nullah. Inspections of the ardeid night roost have been made for any active
ardeid nests. Whilst ardeids have never been recorded nesting at this site,
precautionary checks for active nests or signs of breeding have been made.
Monthly monitoring of the ardeid night
roost location was also conducted by the ecologist from a vantage point, at Ap
Lei Chau Bridge (on the Wong Chuk Hang side), with an unobstructed view over
the area. According to the EM&A Manual, the surveys will commence
approximately one hour before sunset and continue for 20 minutes after sunset,
or until nightfall, which comes sooner. Any aggregation of night roosting
ardeid in the degraded woodland or adjacent area have been located and counted.
During the reporting month, the monthly
night ardeid survey was conducted on 21st
November 2014 commenced at 1635hr.
No ardeids was observed roosted at this location.
Nevertheless, the roosting site at Wong
Chuk Hang shall be maintained in good condition, and proper mitigation measures
will be kept for the tree protection within the site. Proper tree protection
measures have been implemented as far as practicable by the contractor to the
current and potential roost trees retained on site.
Plant Species of Conservation Interest
Detailed field survey led by the ecologist
was undertaken in March and early May 2011 to ascertain the presence of any
rare or protected flora species to be affected. The surveys covered all above
ground works areas of the project and the survey results were presented in the Detailed
Transplanting Baseline Survey Report submitted under the Environmental Permit.
As in the Detailed Transplantating
Baseline Survey Report, two plant species of conservation interest recorded in
the degraded woodland to the south of Wong Chuk Hang Nullah, namely herb Houttuynia cordata and tree Aquilaria sinensis (including
seedlings), and planted young tree Ailanthus
fordii (including seedlings) recorded in a plantation area near Hong Kong
Park will be influenced by the project works. Other plant species of
conservation interest identified will be protected on-site and appropriate tree
protection measures would be established if needed. Health condition of the
most plant species protected in-situ generally remained unchanged as in the
Detailed Transplanting Baseline Survey Report. However, it is noted that health
condition of Ailanthus fordii (tree
no. OCP-T2231), which is outside the active works area at Wong Chuk Hang San
Wai, was found to remain in generally fair physiologically condition. Two Aquilaria sinensis, which are located
outside the active works area to the north of Nam Fung Road, were found in very
poor health condition and suspected to be dead specimens. The two transplanted Aquilaria sinensis have been removed in Nov 2013.
Regular monitoring on the transplanted A. fordii within the works area has been
conducted. The transplanted A. fordii
were in fair health condition and protection fences have been maintained around
the receptor sites. Condition of one transplanted young seedling A.
fordii has grown
satisfactorily with new
leaves developed from the apical bud. while
the retained tree T3 has
remained in satisfactory condition.
According to the Transplanting Proposal
for H. cordata submitted in Sep 2011,
post transplantation maintenance period were undertaken throughout the 12-month
and have been completed.
Mitigation measures on waste management
have been implemented in accordance with the site waste management plans for
the respective civil works contracts. The C&D materials have been disposed
of at the public fill reception facilities while C&D wastes have been
disposed of at the landfills. Operation of the barging point at Telegraph Bay
has been terminated by September 2014. Quantities of wastes disposed in the reporting
period are summarized in the following table:

Implementation of Environmental Mitigation
Measures
Regular site inspections were undertaken
by the ET in accordance with the EM&A Manual to check the implementation of
environmental mitigation measures in the EIA. The contractors' performance on
environmental matters was assessed. The environmental mitigation measures are
being implemented by the civil works contractors where appropriate. A schedule
of the implementation of mitigation measures identified in the SIL(E) EIA is
given in Appendix F.
The findings from the site inspections and
the associated recommendations on improvement to the environmental protection
and pollution control works were raised to the contractors for reference and/
or action. Observations against the implementation of the mitigation measures
recommended in the EP/ EIA are summarized as follows:

Solid and Liquid Waste Management Status
Base on the findings of the site
inspections, the Contractors’ performance in solid and liquid waste management
were acceptable and compliance with the EIA requirements were demonstrated. The
current management standard should be maintained.
The IEC conducted site inspections for respective
works areas on 12, 25 and 27 November 2014. Minor irregularities including
provision of movable noise barriers as necessary and enhancing site drainage
system and dust suppression measures were observed during the site inspections.
Follow up actions had been taken by the respective civil works contractors.
Future key issues envisaged in the coming
month include noise, dust and wastewater from site works, disposal of C&D
wastes arising as well as tree protection on site. The ET will continue the
implementation of the EM&A programme in accordance to the EM&A
Manual.
It is concluded from the environmental
monitoring and audit works for the SIL(E) Project that the construction works
were undertaken in an appropriately environmentally sensitive manner in the
reporting period. The environmental protection and pollution control measures
provided by the respective civil works contractors were generally acceptable
apart from some minor irregularities which were rectified timely by the
contractors.
The ET will continue the implementation of
the EM&A programme in accordance to the EM&A Manual and to a level
consistent with MTRCL's Corporate Sustainability Policy.
