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 ¡V
Zhuhai ¡V Macao Bridge (HZMB). In
order to cope with the anticipated traffic demand, two new road sections
between NWNT and North Lantau ¡V Tuen Mun ¡V 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.

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
In accordance with the Updated
EM&A Manual and the Enhanced TSP Monitoring Plan, impact 1-hour TSP
monitoring was conducted three (3) times every six (6) days and impact 24-hour
TSP monitoring was carried out once 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 on 2, 5, 8, 11, 14, 17, 20,
23, 26 and 29 June 2015 at the five (5) air quality monitoring stations in

The
Action and Limit levels of water quality impact monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix
K.
The schedule for water quality
monitoring in June 2015 is provided in Appendix F.
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.
During this reporting period, no
marine works was carried out in this Contract. It is useful to note that heavy marine
traffic (not associated with the Project) was commonly observed nearby the
Project site and its vicinity.
Impact water quality monitoring was
conducted at all designated monitoring stations in the reporting month. Results and graphical presentations of
impact water quality monitoring are presented in Appendix I.
In this reporting period, a total of
three monitoring events were undertaken in which no Action Level or Limit
Levels of exceedances for impact water quality monitoring was recorded.
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 2.3.

A total of 301.30 km of survey effort was
collected, with 91.6% of the total survey effort being conducted under
favourable weather conditions (ie Beaufort Sea State 3 or below with good
visibility) in June 2015. Amongst
the two areas, 115.90 km and 185.40 km of survey effort were collected from NEL
and NWL survey areas, respectively.
The total survey effort conducted on primary and secondary lines were
220.07 km and 81.23 km, respectively.
The survey efforts are summarized in Appendix J.
A total of 3 groups of fifteen Chinese White Dolphin sightings were
recorded during the two sets of surveys in June 2015. Two sightings were made in NWL while one
sighting was made in NEL during the survey in June 2015. All three sightings were made on primary
lines during on-effort search, and the sighting was not associated with
operating fishing vessel.
None of the sightings was made in the vicinity of the
TM-CLKL Northern Connection Sub-sea Tunnel Section. The distribution of dolphin sightings
during the reporting month is shown in Figure 2.4.
Encounter rates of Chinese White
Dolphins are deduced from the survey effort and on-effort sighting data made

Note:
Overall dolphin encounter rates (sightings per 100 km of survey effort) from
all four surveys are conducted in June 2015 on primary lines only as well as
both primary lines and secondary lines in Northeast and Northwest Lantau.
Due to monthly variation in dolphin
occurrence within the survey area, it would be more appropriate to draw
conclusion on whether any unacceptable impacts on dolphins have been detected
in relation to the construction activities of this Project in the quarterly
EM&A reports, where comparison on distribution, group size and encounter
rates of dolphins between the quarterly impact monitoring period and baseline
monitoring period will be made.
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. In the reporting month, four (4) site
inspections were carried out on 3, 10, 17 and 24 June 2015.
Key observations and recommendations
during the site inspections in this reporting period are summarized in Table 2.11.

marine ecology and waste management 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.
The tentative schedule for
environmental monitoring in July 2015 is provided in Appendix F.
