According to the findings of the Northwest New
Territories (NWNT) Traffic and Infrastructure Review conducted by the Transport
Department, Tuen Mun Road, Ting Kau Bridge, Lantau Link and North Lantau
Highway would be operating beyond capacity after 2016. This forecast has been based on the estimated
increase in cross boundary traffic, developments in the Northwest New Territories
(NWNT), and possible developments in North Lantau, including the Airport
developments, the Lantau Logistics Park (LLP) and the Hong Kong – Zhuhai –
Macao Bridge (HZMB). In order to cope
with the anticipated traffic demand, two new road sections between NWNT and
North Lantau – Tuen Mun – Chek Lap Kok Link (TM-CLKL) and Tuen Mun Western
Bypass (TMWB) are proposed.
An Environmental Impact Assessment (EIA) of TM-CLKL
(the Project) was prepared in accordance with the EIA Study Brief (No.
ESB-175/2007) and the Technical
Memorandum of the Environmental Impact Assessment Process (EIAO-TM). The EIA Report was submitted under the
Environmental Impact Assessment Ordinance (EIAO) in August 2009. Subsequent to the approval of the EIA Report
(EIAO Register Number AEIAR-146/2009), an Environmental Permit (EP-354/2009)
for TM-CLKL was granted by the Director of Environmental Protection (DEP) on 4
November 2009, and EP variation (VEP) (EP-354/2009/A) was issued on 8 December
2010. Subsequent applications for variation

The EM&A programme required environmental
monitoring for air quality, water quality and marine ecology as well as environmental
site inspections for air quality, noise, water quality, waste management,
marine ecology and landscape and visual impacts. The EM&A requirements and related
findings for each component are summarized in the following sections
As per the requirements
under Condition 2.4 of EP-354/2009/D, the Enhanced TSP
Monitoring Plan has been prepared under Contract
No. HY/2012/08. Details of the
monitoring plan are presented in the Enhanced
TSP Monitoring Plan ([1]).
In accordance with the Updated EM&A Manual and the
Enhanced
TSP Monitoring Plan, impact 1-hour TSP monitoring was conducted three (3)
times in every six (6) days and impact 24-hour TSP monitoring was carried out
once in every six (6) days when the highest dust impact was expected. 1-hr and 24-hr TSP monitoring frequency was
increased to three times per day every three days and daily every three days
respectively as excavation works for launching shaft commenced on 24 October
2014.
High volume samplers (HVSs) were used to carry out the
1-hour and 24-hour TSP monitoring in the reporting quarter at the five (5) air
quality monitoring stations in accordance with the requirements stipulated in
the Updated EM&A Manual (Figure 2.1; Table 2.1). Wind anemometer was installed at the rooftop

Three (3) Action Level exceedances of 1-hour TSP were
recorded in the air quality monitoring of this reporting period. Summary of Exceedances for Air Quality Impact
Monitoring in this Reporting Quarter is detailed in Table 2.13.
Seawall Enhancement Works at Northern Landfall has
been completed on 31 December 2017.
Notification of suspension of water quality monitoring has been approved
by EPD on 2 March 2018. Water Quality
Monitoring will be resumed prior to the start of Seawall Modification Works at
Southern Landfall in January 2019.
Impact dolphin monitoring is required to be conducted
by a qualified dolphin specialist team to evaluate whether there have been any
effects on the dolphins. In order to
fulfil the EM&A requirements and make good use of available resources, the
on-going impact line transect dolphin monitoring data collected by HyD’s Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge. Hong Kong
Link Road - Section between Scenic Hill and Hong Kong Boundary Crossing
Facilities on the monthly basis is adopted to avoid duplicates of survey

Dolphin monitoring should cover all transect lines in
Northeast Lantau (NEL) and the Northwest Lantau (NWL) survey areas twice per
month throughout the entire construction period. The monitoring data should be compatible
with, and should be made available for, long-term studies of small cetacean
ecology in Hong Kong. In order to
provide a suitable long-term dataset for comparison, identical methodology and
line transects employed in baseline dolphin monitoring was followed in the
impact dolphin monitoring.
The impact dolphin monitoring was carried out in the
NEL and NWL along the line transect as depicted in Figure 2.2. The co-ordinates of all transect lines are
shown in Table 2.6 below.

Whilst one limit level exceedance was observed for the
quarterly dolphin monitoring data between March and May 2018, no
unacceptable impact from the construction activities of this Contract was
recorded from the general observations.
Although the dolphins infrequently occurred along the
alignment of TM-CLKL Northern Connection Sub-Sea Tunnel Section in the past and
during the baseline monitoring period, it is apparent that dolphin usage has
been significantly reduced in NEL.
It is critical to monitor the dolphin usage in North
Lantau region in the upcoming quarters to determine whether the dolphins are
continuously affected by the various construction activities in relation to the
HZMB-related works, and whether suitable mitigation measure can be applied to
revert the situation.
There was no dredging, reclamation or marine sheet piling works in
open waters during this reporting period. Thus, Passive Acoustic
Monitoring (PAM) and the day-time monitoring of Dolphin Exclusion Zone (DEZ) by
dolphin observers were not in effect during the reporting period.
Site inspections were carried out on a weekly basis to
monitor the implementation of proper environmental pollution control and
mitigation measures under the Contract.
Thirteen (13) site inspections were carried out in the reporting quarter
on 7, 14, 21 and 28 March 2018;
4, 11, 18 and 25 April 2018;
2, 9, 16, 23 and 30 May 2018.
Key observations during the site inspections in this
reporting period are summarized in Table
2.10.

In response to the site audit findings, the
Contractors carried out all corrective actions.
A summary of the Implementation Schedule of
Environmental Mitigation Measures (EMIS) is presented in Appendix C. The necessary mitigation measures relevant to
this Contract were implemented properly.
For
air quality impact monitoring, a total of thirty-one monitoring events for both
1-hour TSP and 24-hour TSP were undertaken in which three (3) Action Level
exceedances of 1-hour TSP were recorded in the air quality monitoring of this
reporting period. (Table 2.13).
Table 2.13 Summary of
Exceedances for Air Quality Impact Monitoring in this Reporting Quarter
|
One (1) Limit Level exceedance was observed for the
quarterly dolphin monitoring data between March and May 2018, whilst no
unacceptable impact from the construction activities of the TM-CLKL Northern
Connection Sub-sea Tunnel Section on Chinese White Dolphins was noticeable from
general observations.
Cumulative statistics are provided in Appendix I.
The Environmental Complaint Handling Procedure is
provided in Figure 2.3.
No
environmental complaint was received in this reporting period.
No environmental summons was received in this
reporting period.

Potential environmental impacts arising from the above
upcoming construction activities in the coming quarterly period are expected to
be mainly associated with dust, marine ecology and waste management issues.
Impact monitoring for air quality and marine ecology
(include dolphin monitoring) are scheduled to continue for the next reporting
period.
This Eighteenth Quarterly EM&A Report presents the
findings of the EM&A activities undertaken during the period from 1 March
2018 to 31 May 2018, in accordance with the Updated EM&A Manual and the
requirements of EP-354/2009/D.
Air quality (including 1-hour TSP and 24-hour TSP and
dolphin monitoring were carried out in the reporting period. Three (3) Action Level exceedances of 1-hour
TSP were recorded in the air quality monitoring of this reporting period.
A total of 9 groups of 30 Chinese White Dolphins
sightings were recorded during the six sets of surveys
in this reporting quarter. All dolphin sightings were made during on-effort search, and eight of
the nine on-effort dolphin sightings were made on primary lines. Whilst one limit level exceedance was
observed for the quarterly dolphin monitoring data between March and May 2018, no
unacceptable impact from the construction activities of this Contract was
recorded from the general observations. Although the dolphins infrequently occurred
along the alignment of TM-CLKL Northern Connection Sub-Sea Tunnel Section in
the past and during the baseline monitoring period, it is apparent that dolphin
usage has been significantly reduced in NEL.
It is critical to monitor the dolphin usage in North Lantau region in
the upcoming quarters, to determine whether the dolphins are continuously
affected by the various construction activities in relation to the construction
works of the Contract, and whether suitable mitigation measure can be applied
to improve the situation.
Thirteen weekly environmental site
inspections were carried out in the reporting period. Recommendations on remedial actions provided
for the deficiencies identified during the site audits were properly
implemented by the Contractor. No
non-compliance event was recorded during the reporting period.
The monitoring programme has been reviewed and was
considered as adequate to cater for the nature of works in progress. Change to the monitoring programme
was thus not recommended at this stage.
The monitoring programme will be evaluated as appropriate in the next
reporting period. The ET will keep track
on the construction works to confirm compliance of environmental requirements
and the proper implementation of all necessary mitigation measures.
