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 waste management issues. Although there are no dredging, reclamation
and marine works in the coming quarter, other potential environmental impacts such
as dust and marine ecology should also be addressed.
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 two action level exceedances were observed for
the quarterly dolphin monitoring data between September 2015 and November 2015,
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 September 2015; 9, 14, 20 and 28 October 2015; 4, 11, 18 and 25 November
2015.
Key observations during the site inspections in this
reporting period are summarized in Table 2.10.

Two action level exceedances of impact dolphin monitoring
were 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
reporting period.
No summons/ prosecution was
received during the reporting period.
Statistics on complaints, notifications of summons and
successful prosecutions are summarized in Appendix I.
As informed by the Contractor, the major works for the
Project in the coming quarter are summarized in Table 3.1.

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 waste management issues. Although there are no dredging, reclamation
and marine works in the coming quarter, other potential environmental impacts
such as dust and marine ecology should also be addressed.
Impact monitoring for air quality and marine ecology
(include dolphin monitoring) are scheduled to continue for the next reporting
period.
This Eighth Quarterly EM&A Report presents the
findings of the EM&A activities undertaken during the period from 1 September
2015 to 30 November 2015, 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 18 groups of 95 Chinese White Dolphin
sightings were recorded during the six sets of surveys
from September 2015 to November 2015. Whilst
two action Level exceedances were recorded for the quarterly dolphin monitoring
data between September 2015 and November 2015, 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.
