The “Expansion of Hong Kong International
Airport into a Three-Runway System” (the Project) serves to meet the future air
traffic demands at Hong Kong International Airport (HKIA). On 7 November
2014, the Environmental Impact Assessment (EIA) Report (Register No.:
AEIAR-185/2014) for the Project was approved and an Environmental Permit (EP)
(Permit No.: EP-489/2014) was issued for the construction and operation of the
Project.
Airport Authority Hong Kong (AAHK) commissioned
Mott MacDonald Hong Kong Limited (MMHK) to undertake the role of Environmental
Team (ET) for carrying out the Environmental Monitoring & Audit (EM&A)
works during the construction phase of the Project in accordance with the
Updated EM&A Manual.
This is the 7th Construction Phase
Monthly EM&A Report for the Project which summarizes the monitoring results
and audit findings of the EM&A programme during the reporting period from 1
July 2016 to 31 July 2016.
Key Construction Activities in the Reporting
Month
The key construction activities of the Project
carried out in the reporting month were related to Contract P560(R) Aviation
Fuel Pipeline Diversion Works (Contract P560(R)) which involved installation of
horizontal directional drilling (HDD) casing, drilling of HDD pilot hole and
stockpiling of excavated materials from HDD operation. Site investigation
works were also carried out to support design process.
No construction work was carried out on Sheung Sha Chau Island during the ardeid’s
breeding season in the reporting month in accordance with the Updated EM&A
Manual.
EM&A
Activities Conducted in the Reporting Period
The monthly EM&A programme was undertaken
in accordance with the Updated EM&A Manual of the Project. During the
reporting period, the ET conducted thirty sets of air quality measurements,
twenty sets of construction noise measurements, as well as four environmental
site inspections, landscape & visual and waste monitoring for the Project’s construction works.
On the implementation of the SkyPier
Plan, the daily movements of all SkyPier HSFs in July
2016 were within the maximum daily cap number. A total of 836 HSF
movements under SkyPier Plan were recorded. All HSFs
had travelled through the SCZ with prevailing speed under 15 knots (8.0 to 14.8
knots) in compliance with the SkyPier Plan. Seven
ferry movements were not strictly following the diverted route. In
summary, the ET and IEC have audited the HSF movements against the SkyPier Plan and conducted follow up investigation or
actions accordingly.
Results of Impact Monitoring
All scheduled 1-hour total suspended
particulate (TSP), noise and waste monitoring were completed in the reporting
period for the relevant construction activities. No exceedance of the Action/
Limit Levels was recorded.

Monitoring Methodology
3.4.1
Monitoring Procedure
The monitoring procedures involved in the noise
impact monitoring can be summarised as follows:
a. The sound level meter was set on a
tripod at least a height of 1.2 m above the ground for free-field measurements
at monitoring stations NM1A, NM4, NM5 and NM6. A correction of +3 dB(A) was applied to the free field measurements.
b. Façade measurements were made at the
monitoring station NM3A.
c. Parameters such as frequency
weighting, time weighting and measurement time were set.
d. Prior to and after each noise
measurement, the meter was calibrated using the acoustic calibrator. If
the difference in the calibration level before and after measurement was more
than 1 dB(A), the measurement would be considered
invalid and repeat of noise measurement would be required after re-calibration
or repair of the equipment.
e. During the monitoring period, Leq,
L10 and L90 were recorded. In addition, site
conditions and noise sources were recorded on a record sheet.
f. Noise measurement results were
corrected with reference to the baseline monitoring levels.
g. Observations were recorded when high intrusive
noise (e.g. dog barking, helicopter noise) was observed during the monitoring.
3.4.2
Maintenance and Calibration
The maintenance and calibration procedures are
summarised below:
a. The microphone head of the sound
level meter was cleaned with soft cloth at regular intervals.
b. The meter and calibrator were sent
to the supplier or laboratory accredited under Hong Kong Laboratory
Accreditation Scheme (HOKLAS) to check and calibrate at yearly intervals.
Calibration certificates of the
sound level meters and acoustic calibrators used in the noise monitoring are
provided in Appendix C.

As the construction activities were small in
scale during the reporting period and far away from the monitoring stations,
major sources of noise dominating the monitoring stations observed during the
construction noise impact monitoring were aircraft noise at NM3A and NM5,
aircraft noise and helicopter noise at NM6, road traffic noise at NM1A and
school activities at NM4 in this reporting month.
No exceedance of the Action/ Limit Level was
recorded at all monitoring stations in the reporting period.
4.1
Monitoring Requirements
In accordance with the Updated EM&A Manual,
the waste generated from construction activities was audited once per week to
determine if wastes are being managed in accordance with the Waste Management
Plan (WMP) prepared for the Project, contract-specific WMP, and any statutory
and contractual requirements. All aspects of waste management including waste
generation, storage, transportation and disposal were assessed during the
audits. The Action and Limit levels of the construction waste are provided in Table 4.1.

Waste
Management Status
Weekly monitoring of the Project construction
works was carried out by the ET on 6, 14, 20 and 27 July 2016 to check and
monitor the implementation of proper waste management practices during the
construction phase.
For Contract P560(R) Aviation Fuel
Pipeline Diversion Works, recommendations were provided during monitoring
including proper plugging of drip tray to avoid any leakage on 6 July 2016,
replacement/ repair of broken drip tray on 20 July 2016. The contractor had
followed up with implementation of mitigation measures.
The P560(R) Contractor was advised
to properly maintain a recording system, maximize the reuse of C&D
materials and properly maintain site tidiness.
Based on the updated information, about 284 m3 excavated
materials were produced from the HDD launching site in
July 2016. The generated excavated materials were temporarily stored at storage
and stockpiling area at Chun Ming Road adjacent to Tradeport
Logistic Centre on the airport island. The excavated material will be reused in
the Project.
In addition, metals, paper and
plastic were recycled during the reporting month. 1.2 tonnes of general refuse
were disposed of to the West New Territories (WENT) Landfill in July 2016. No
Construction and Demolition (C&D) material was disposed off-site during the
reporting month. No exceedances of the Action and Limit Levels were recorded in
the reporting period.
5.1
Environmental Site Inspection
Weekly site inspection of the construction
works was carried out by the ET on 6, 14, 20 and 27 July 2016 to monitor the
implementation of proper environmental pollution control and mitigation
measures for the Project. Site inspections were also conducted independently by
the Project’s Independent Environmental Checker (IEC) on 8 and 20 July 2016. Observations have been recorded in
the site inspection checklists and passed to the Contractor together with the
appropriate recommended mitigation measures where necessary.
The key observations from site
inspection and associated recommendations were related to the improvement of
efficiency of wastewater treatment facilities, proper maintenance of drip tray
and provision of wheel washing before leaving the construction site.
In addition, CNP compliance check
of the use of powered mechanical equipment during restricted hour was carried
out by the ET on 11 July 2016. The use of powered mechanical equipment was
complied with the requirements of CNP.
A summary of implementation status
of the environmental mitigation measures for the construction phase of the
Project during the reporting period is provided in Appendix
B.
5.2
Audit of Route Diversion and Speed Control of the SkyPier High Speed Ferries
The
Marine Travel Routes and Management Plan for High Speed Ferries of SkyPier (the SkyPier Plan) has
been submitted to the Advisory Council on the Environment (ACE) for comment and
subsequently submitted to and approved by EPD in November 2015 under EP Condition
2.10. The approved SkyPier Plan is available on the
dedicated website of the Project. In the SkyPier
Plan, AAHK committed to implementing the mitigation measure of requiring high
speed ferries (HSFs) of SkyPier travelling between
HKIA and Zhuhai / Macau to start diverting the route with an associated speed
control across an area (i.e. Speed Control Zone (SCZ)) with high Chinese White
Dolphin (CWD) abundance. The route diversion and speed restriction at the
SCZ have been implemented since 28 December 2015.
Key audit findings for the SkyPier
HSFs travelling to/from Zhuhai and Macau against the requirements of the SkyPier Plan during the reporting period are summarized in
Table 5.1. The daily movements of all SkyPier HSFs
in July 2016 were within the maximum daily cap number. Status of compliance
with annual daily average of 99 movements will be further reviewed in the
annual EM&A Report.
In total, 836 ferry movements between HKIA SkyPier and Zhuhai / Macau were recorded in July 2016 and
the data are presented in Appendix H. The time spent for the SkyPier
HSFs travelled through the SCZ in July were presented in Figure 5-1. It will take 9.6 minutes to travel through the SCZ
when the SkyPier HSFs adopt the maximum allowed speed
of 15-knot within the SCZ. Figure
5-1 shows that all the SkyPier HSFs spent more than 9.6 minutes to travel through
the SCZ.
Figure 5‑1 Duration of
the SkyPier HSFs travelled through the SCZ for July
2016
Seven ferry movements were not strictly following the
diverted route as recorded on 1, 8, 9, 11, 12, 15 and 22 July 2016. Notices
were sent to the ferry operators and the investigation results revealed that
they were related to safety / emergency situations presented as follows:
￭
Case on 1,
8, 9, 11, 12 and 15 July 2016: HSF captains reported that the deviations of routing were due to
strong tidal current. Ferry operators were requested
to provide further supporting evidence as justification. Follow up action will
be taken if valid reasons / supporting evidence cannot be provided.
￭
Case on 22
July 2016: This case is under investigation.
Another deviation case of not strictly following the
diverted route on 21 June 2016 has been followed up. Investigation found that
the vessel captain required to give way to
floating obstructions including buoy, marine refuse and bamboo raft for safety
reason. After that, the HSF returned to the normal route following the SkyPier Plan.

Key Environmental Issues for the Coming Reporting
Period
The key environmental issues for the Project in
the coming reporting period are expected to be associated with the construction
activities of P560(R) Contract and these include:
￭
Generation of dust from
construction works;
￭
Noise impact from
operating equipment and machinery on-site;
￭
Generation of site
surface runoffs and wastewater from activities on-site;
￭
Management of
stockpiles;
￭
Sorting, recycling,
storage and disposal of general refuse and construction waste;
￭
Management of chemicals
and avoidance of oil spillage on-site.
The impact water quality and CWD monitoring, and ecological monitoring at Sha Chau will be
commenced in August 2016. The implementation of required mitigation measures by
the Contractor will be monitored by the ET.
6.3
Monitoring Schedule for the Coming Reporting Period
The impact water quality and CWD monitoring
will be commenced on 1 August 2016. A tentative schedule of the planned
environmental monitoring work in the next reporting period is provided in Appendix D.
The key construction activities of the Project
carried out in the reporting month were related to the Contract P560 Aviation
Fuel Pipeline Diversion which involved installation of HDD casing, drilling of
HDD pilot hole and stockpiling of excavated materials
from HDD operation. Dust suppression measures including wheeling
washing, watering and covering of excavated materials and establishment of site
hoarding have been implemented.
Construction dust, noise and waste monitoring
were carried out in the reporting period. No breach of the Action or Limit
Levels in relation to the air quality, construction noise and waste monitoring
were recorded in the reporting month. All site observations made by the
ET were recorded in the site inspection checklists and passed to the Contractor
together with the recommended follow-up actions.
On the implementation of the SkyPier
Plan, the daily movements of all SkyPier HSFs in July
2016 were within the maximum daily cap number. A total of 836 HSF
movements under SkyPier Plan were recorded. All HSFs
had travelled through the SCZ with prevailing speed under 15 knots (8.0 to 14.8
knots) in compliance with the SkyPier Plan. Seven
ferry movements were not strictly following the diverted route. In
summary, the ET and IEC have audited the HSF movements against the SkyPier Plan and conducted follow up investigation or
actions accordingly.
