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 (VEPs), 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.

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 3, 6, 9, 12, 15, 18, 21, 24, 27 and 30
March 2016 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 meter was
installed at the rooftop of ASR5 for logging wind speed and wind
direction. Details of the equipment
deployed are provided in Table 2.2. Copies of the calibration certificates for

The weather condition during the monitoring period
varied from sunny to cloudy. The major
dust sources in the reporting period included construction activities under the
Contract as well as nearby traffic emissions.
A total of 10 monitoring events were undertaken in
which no Action or Limit Level exceedances of 1-hr TSP were recorded in this
reporting month. No Action or Limit
Level exceedances for 24-hr TSP were record.
Meteorological information collected at the ASR5,
including wind speed and wind direction, is provided in Appendix H.
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

The Action and Limit levels of impact dolphin
monitoring are shown in Appendix D. The Event and Action plan is presented in Appendix J.
Dolphin monitoring was carried out on 7, 11, 22 and 23
of March 2016. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
A total of two groups of 4 Chinese
White Dolphins sightings were recorded
during the two sets of surveys in March 2016. Both dolphin sightings
were made in NWL, while none was sighted in NEL. One of the two dolphin
sightings was made on
primary lines during on-effort search, and neither dolphin group was associated with any
operating fishing vessel.
None of the dolphin sightings was made in the
proximity of the TM-CLKL alignment. The
distribution of dolphin sightings during the reporting month is shown in Figure 2.3.
Encounter rates of Chinese White Dolphins are deduced
from the survey effort and on-effort sighting data made under favourable conditions (Beaufort 3 or below) in March 2016
with the results present in Tables 2.7 and 2.8.

Note:
Overall dolphin encounter rates (sightings per 100 km of survey effort) from
all four surveys are conducted in March 2016 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, five (5) site inspections were carried out on 2,
9, 16, 23 and 30 March 2016.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.9.

The Contractor has rectified all of the observations
as identified during environmental site inspections in the reporting
month.
The Contractor had submitted application form for
registration as chemical waste producer under the Contract. Sufficient numbers of receptacles were
available for general refuse collection and sorting.
Wastes generated during this reporting period included
mainly construction wastes (inert and non-inert), recyclable materials and chemical
wastes. Reference has been made to the
waste flow table prepared by the Contractor (Appendix L). The quantities of different types of wastes
are summarized in Table 2.10.
