are mainly associated with dust, water quality, 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-354/2009/A) 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
December 2018 at the five (5) air quality monitoring stations in accordance

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

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 3, 5, 10 and 12
of December 2018. The dolphin monitoring
schedule for the reporting month is shown in Appendix F.
Two group of 6 Chinese White Dolphins sightings was
recorded during the two sets of surveys in December 2018. All the dolphin sightings were made in NWL,
while none was sighted in NEL. All
dolphin sightings were made during on-effort search and on primary lines. The dolphin groups were not associated with
any operating fishing vessel.
No dolphin sighting 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 December 2018
with the results present in Tables 2.7 and 2.8.

Overall dolphin encounter rates (sightings per 100 km of survey effort) from all
four surveys are conducted in December 2018 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.
Daily
marine mammal exclusion zone was in effect during the period of silt curtain installation
in open waters under this Contract. No
sighting of the Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in December 2018 during the exclusion
zone monitoring.
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 5,
12, 19 and 27 December 2018.
Key observations and recommendations during the site
inspections in this reporting period are summarized in Table 2.9.
