Future Key Issues
As informed by the Contractor, Phase I Reclamation works
for the Northern Landfall was substantially completed in December 2014, a
proposal letter was sent to EPD on 21 May 2015 to seek approval for the
temporary suspension of Water Quality Monitoring. Subsequently, a letter from EPD on 5 June
2015 stated that they have no strong objection to the temporary suspension of
the water quality monitoring. Water
Quality Monitoring was suspended from 6 June 2015 effectively and will resume
when Phase II Reclamation commences in the fourth quarter of 2016 tentatively.
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.
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-354/2009A) was issued on 8 December
2010. Subsequent applications for
variation of environmental permits (VEP), EP-354/2009/B,
EP-354/2009/C and EP-354/2009/D, were
granted on 28 January 2014, 10 December 2014 and 13 March 2015, respectively.

As informed by the Contractor, Phase I Reclamation
works for the Northern Landfall was substantially completed in December 2014, a
proposal letter was sent to EPD on 21 May 2015 to seek approval for the
temporary suspension of Water Quality Monitoring. Subsequently, a letter from EPD on 5 June
2015 stated that they have no strong objection to the temporary suspension of
the water quality monitoring. Water
Quality Monitoring was suspended from 6 June 2015 effectively and will resume
when Phase II Reclamation commences in the fourth quarter of 2016
tentatively.
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 effort.

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 December 2015 and February 2016, 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 2, 9, 16, 23 and 30 December 2015; 6, 13, 20 and 27 January 2016; 3, 11, 17
and 24 February 2016.
Key observations during the site inspections in this
reporting period are summarized in Table
2.10.

One limit level exceedance of impact dolphin
monitoring was recorded in this reporting quarter. Following the review of monitoring data and
marine works details in accordance with the procedures stipulated in the Event
and Action Plan of the Updated EM&A Manual, there is no evidence showing
that the sources of impact directly related to the construction works under
this Contract that may have affected the dolphin usage in the NEL region. Detailed investigation findings are presented
in Appendix I.
Cumulative statistics are provided in Appendix I.
The Environmental Complaint Handling Procedure is
provided in Figure 2.3.
No non-compliance event was recorded during the
reporting period.
No environmental complaint was received in the

As informed by the Contractor, Phase I Reclamation
works for the Northern Landfall was substantially completed in December 2014, a
proposal letter was sent to EPD on 21 May 2015 to seek approval for the
temporary suspension of Water Quality Monitoring. Subsequently, a letter from EPD on 5 June
2015 stated that they have no strong objection to the temporary suspension of
the water quality monitoring. Water Quality
Monitoring was suspended from 6 June 2015 effectively and will resume when
Phase II Reclamation commences in the fourth quarter of 2016 tentatively.
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 Ninth Quarterly EM&A Report presents the
findings of the EM&A activities undertaken during the period from 1
December 2015 to 29 February 2016, 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. No Action or Limit Level exceedances for 1-hr
TSP were recorded. No Action or Limit
Level exceedances for 24-hr TSP were record.
A total of 14 groups of 57 Chinese White Dolphin
sightings were recorded during the six sets of surveys
from December 2015 to February 2016.
Whilst one limit level exceedance was recorded for the quarterly dolphin
monitoring data between December 2015 to February 2016,
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. 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.
No environmental complaint was received during the
reporting period.
No summons/ prosecution was received
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.
