Breaches of Action and Limit Levels for Air Quality
No exceedance
of Action and Limit Levels was recorded for construction air monitoring in the
reporting month.
Breaches of Action and Limit Levels for Noise
No exceedance
of Action and Limit Levels was recorded for construction noise monitoring in
the reporting month.
Breaches of Action and Limit Levels for Water Quality
No exceedance
of Action and Limit Levels was recorded for impact water quality monitoring in
the reporting month.
Impact Dolphin Monitoring
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
was noticeable from general observations.
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.
Daily
marine mammal exclusion zone monitoring was undertaken during the period of
marine works under this Contract. Passive
Acoustic Monitoring (PAM) was also implemented for the detection of marine
mammal when marine works were carried out outside the daylight hours under this
Contract. No sighting of the Indo-Pacific
humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) was recorded in October
2014 during the exclusion zone monitoring.
Coral Monitoring
The Fourth
Quarterly Post-translocation Coral Monitoring was conducted on 23 October 2014 and
the results will be detailed in the Fourth
Quarterly Post-Translocation Coral Monitoring Report.
Environmental Complaints, Non-compliance & Summons
No environmental
complaint, notification of summons and successful prosecution was received in
the reporting month.

Future Key Issues
Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of November 2014 are mainly associated with dust, noise,
marine 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 ¡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
(EP-354/2009A) was issued on 8 December 2010.
Under
Contract No. HY/2012/07,
Gammon Construction Limited (GCL) is commissioned by the Highways Department (HyD) to undertake the design and construction of the

The Action and
Limit levels of dolphin impact monitoring are shown in Appendix D. The Event and Action plan is presented
in Appendix L.
A total of ten (10) groups of thirty (30) Chinese
White Dolphins were sighted during the two sets of monitoring surveys in
October 2014. All sightings were
made in NWL during the two sets of surveys in October 2014, while no dolphin
was sighted at all in NEL in this month.
All except two (2) sightings 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 October 2014 are shown in Tables 2.12 and 2.13.

The average group size of
Chinese White Dolphins in October 2014 was 3.0 individuals
per group, which was lower than the ones in previous months of dolphin
monitoring. Six (6) of the ten (10)
dolphin groups were composed of one to three (1-3) animals, while only one
slightly larger dolphin group with six (6) animals was sighted during the
monitoring period. Detailed results
of dolphin monitoring in this reporting month are
presented in Appendix K.
Daily 250 m marine
mammal exclusion zone monitoring was undertaken during the period of marine
works activities being undertaken. Passive Acoustic Monitoring (PAM) was also implemented for the detection
of marine mammal when marine works were carried out outside the daylight hours
under this Contract. No
sighting of Indo-Pacific humpback dolphin Sousa
chinensis (i.e. Chinese White Dolphin) were
recorded in October 2014 during the exclusion zone monitoring.
The Fourth
Quarterly Post-translocation Coral Monitoring was conducted on 23 October 2014 and
the results will be detailed in the Fourth
Quarterly Post- Translocation Coral Monitoring Report.

Potential
environmental impacts arising from the above upcoming construction activities
in the next reporting month of November 2014 are mainly associated with dust, noise,
marine water quality, marine ecology and waste management issues.
This Twelfth Monthly
EM&A Report presents the findings of the EM&A activities undertaken
during the period from 1 to 31 October 2014, in accordance with the Updated
EM&A Manual and the requirements of EP-354/2009/B.
A total of ten
groups of thirty (30) Chinese White Dolphins were sighted during the two sets
of monitoring surveys in October 2014.
All sightings were made in NWL during the two sets of surveys in October
2014, while no dolphin was sighted at all in NEL in this month. All except two (2) sightings 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.
The ET will
keep track on the construction works to confirm compliance of environmental requirements
and the proper implementation of all necessary mitigation measures.
