Introduction
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
(EP-354/2009A) was issued on 8 December 2010.

Monitoring Parameter, Frequencies and Duration
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.

2.4.5
Action
& Limit Levels
The Action and
Limit levels of dolphin impact monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix L.
2.4.6
Monitoring Schedule for the Reporting Month
Dolphin monitoring was carried out on 2, 11,
19 and 22 of September 2014 (Appendix F).
2.4.7
Results and Observations
A total of 298.52 km of survey effort was
collected, with 100% of the total survey effort being conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or
below with good visibility) during the September’s surveys. Among the two areas, 116.40 km and 182.12
km of survey effort were collected from NEL and NWL survey areas
respectively. The total survey
effort conducted on primary and secondary lines were 214.57 km and 83.95 km
respectively. The survey efforts
are summarized in Appendix K.
A total of eight (8) groups of thirty-four (34)
Chinese White Dolphins were sighted during the two sets of monitoring surveys
in September 2014. All sightings
were made in NWL during the two sets in September 2014, while no dolphin was
sighted at all in NEL in this month.
All except one sighting were made on primary lines during on-effort
search, and none of the dolphin groups was associated with operating fishing
vessel. The distribution of dolphin
sightings during the reporting month is shown in Figure 2.5.
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 September 2014 are shown in Tables 2.12 and 2.13.

surveys are conducted in September 2014 on primary lines only as well as both
primary lines and secondary lines in Northeast and Northwest Lantau
The average
group size of Chinese White Dolphins in September 2014 was 4.25 individuals per
group. Three (3) dolphin groups
were composed of one to three (1-3) animals, while five (5) dolphin groups were
composed of five to six (5-6) animals with slightly larger group size. Detailed results of dolphin monitoring in
this reporting month are presented in Appendix K.
Due
to monthly variation in dolphin occurrence within the study area, it would be
more appropriate to draw conclusion on whether any impacts on dolphins have
been detected related to the construction activities of the TM-CLKL Southern
Connection Viaduct Section 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.
2.4.8
Marine Mammal Exclusion Zone Monitoring
Daily 250 m marine
mammal exclusion zone monitoring was undertaken during the period of marine
works activities being undertaken. No sighting of Indo-Pacific
humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) were recorded in
September 2014 during the exclusion zone monitoring.
No
Post-Translocation Coral Monitoring Exercise was conducted in the reporting month.
2.6
EM&A Site inspection
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 4, 10, 19, 25 and 30 September 2014.
Key observations during the site
inspections are summarized in Table 2.14.

Conclusions
and recommendations
This Eleventh Monthly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 to 30 September 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/B.
Air quality (including 1-hour TSP and 24-hour TSP),
noise, water quality, and dolphin monitoring were carried out in the reporting month. Results for water quality monitoring, 1-hr
TSP, 24-hr TSP and noise monitoring complied with the Action and Limit levels
in the reporting period.
A total of eight (8) groups of thirty-four (34) Chinese White Dolphins
were sighted during the two sets of monitoring surveys in September 2014. All sightings were made in NWL during
the two sets of surveys in September 2014, while no dolphin was sighted at all
in NEL in this month. All except
one (1) sighting were made on primary lines during on-effort search, and none of
the dolphin groups was associated with operating fishing vessel. During this month of dolphin monitoring,
no unacceptable impact from the construction activities of the TM-CLKL Southern
Connection Viaduct Section on Chinese White Dolphins were noticeable from
general observations.
Environmental site inspection was carried out five (5)
times in September 2014.
Recommendations on remedial actions were given to the Contractor for the
deficiencies identified during the site audits.
No environmental complaint, notification of summons
or prosecution was received in the reporting month.
The ET will
keep track on the construction works to confirm compliance of environmental
requirements and the proper implementation of all necessary mitigation
measures.
